How to make a rat cage?

The traditional squirrel cage is hand-woven with iron wire, which is a typical bait-pulling structure. Although this "classic" streamlined structure has gone through thousands of years, it has not changed much. From the appearance, the mouse cage has only two actions: "open" and "close", that is, the cage door is opened (waiting for the mouse to enter); Close the cage door, ie the mouse is caught and trapped. In fact, from the mechanical point of view, the working principle of the squirrel cage is the mutual transformation process of two kinds of balance. From the unstable balance of cage door opening after supporting mechanism to the stable balance of cage door closing. The latter is a stable balance in a natural state that is not controlled by the mechanism, while the former is an unstable balance controlled by the mechanism after the mechanism is set, which is easily destroyed by other external forces-as long as the mouse is gently pulled, it can restore its stable balance and close the cage door. Many families, in order to be safe and avoid the pollution of rat carcasses, choose traditional rat cages to catch rats. But they often worry that their rat catching rate is not ideal: rats don't want to go into cages; The bait was finished, but the mouse was not caught; Or grab it and run away. After analysis and anatomy, there are four actions in the process of catching rats in traditional rat cages: ① the rats enter the cage; 2 eat bait; ③ Pull the bait hook forward and start the mechanism; (4) Close the cage door and trap the mouse. That is to say, after the mouse enters the cage, it is necessary to pull the bait hook to the door of the cage and start the mechanism according to the designer's wishes when eating the bait-only after all four actions are completed in the process of catching the mouse can the mouse be caught. It was not easy to lure the mouse into the cage, but it was even harder to pull the hook forward after entering the cage. If the mouse eats the bait carefully and doesn't pull the bait hook, or the mouse pulls the bait hook to the left, right or back by mistake instead of pulling forward, it can't trigger and start the mechanism of closing the cage door and catching the mouse. This is an important reason for the low rate of catching rats in traditional rat cages. It seems that in order to catch mice in traditional rat cages, we must first let the mice dare to enter the cage and be willing to enter it; Secondly, mice are required to complete the above specific procedures according to people's wishes, and they are required to pull the bait hook forward "correctly" when eating bait. If the program executed by the mouse is not up to standard, "error"-if you don't pull forward, you can't catch the mouse. Obviously, there are too many procedures and actions in the traditional mouse cage to catch mice, and it is easy to "make mistakes". In order to improve the rat catching rate, we should reduce the movements and establish a new program that mice are not easy to make mistakes. Catching rats with traditional rat cages also requires that the rat cages reach a certain production level and eliminate the factors that affect the entry of rats into the cages; Only by eliminating all the factors that lead the mouse to escape can we catch the mouse. The traditional manufacturing method of squirrel cage is primitive and the precision of parts is not enough; Eye holes are hand-woven, with large errors; The bottom of the cage is uneven, so it is not easy to lay flat on the horizontal plane; Some cages will shake when the mouse enters, which will make the mouse feel scared; Or the cage entry channel is not flat enough, unobstructed enough, and there are obstacles. It will make mice afraid to enter easily. That is to say, the traditional manufacturing process of rat cages is extensive, the closing parts are not accurate enough, the performance is not stable enough, they are easy to break, the holes are different in size, and individual meshes are too large, which are easy to cause the bait to be eaten up without catching rats or to escape after catching rats. The house mouse is an animal with high IQ. After being captured, it tried every means to escape. The stout mouse even bit the wire and squeezed the cage to escape. Therefore, the mouse cage should be small and trouble-free, the parts should have enough accuracy, and the size of the holes should be quite uniform, so as to catch mice. Without reform, it is impossible to change the wrong view of "it is difficult to catch rats with equipment" in consumers' minds. All kinds of house mice and farm rodents are necessary and scarce experimental animals, and researchers and rodent control workers hope that mousetraps that can easily catch live mice will be born as soon as possible. Rat cages are the first choice for killing rats in families, hotels, food factories and other places. In order to meet the needs of people at different levels, the task of designing easy-to-catch live rats has historically fallen on the shoulders of modern ratter. In view of the shortcomings of traditional rat cages, people have been designing new ones for a long time. In 1980s, some people designed and made a perfect mousetrap on the basis of studying and analyzing various folk mousetraps in past dynasties. In recent years, they also searched hundreds of inventions of mousetraps that have been patented since 1985. However, researchers found that most inventors didn't understand the behavior, life rules and habits of mice, and only designed them behind closed doors according to subjective wishes, which made many inventions impractical. Although the idea is clever, it doesn't work in practice: some inventions make it difficult for mice to "execute" a specific mouse catching program according to the designer's wishful thinking; Some have poor sensitivity and it is difficult to catch mice; Some inventions can fully show the wisdom of the inventors and gild the lily. Although rats can be caught, the structure is too complicated and the cost is too high. If these unrealistic inventions are used reluctantly, rats can't be caught or the price is too high, and people will fall into a predicament of no interest or little interest. Catching mice is a business that needs the participation of millions of people. The mousetrap must be exquisite in structure, durable, reliable in performance, cheap and affordable, and everyone can use it. In fact, it has been people's wish for many years to design a mousetrap with high mousetrap rate, simple use, safety for people and animals, suitability for different environments, no need of energy and no harm to mice. Every mouse has weight. Changing the mousetrap from pulling bait to pedaling reduces the program of mousetrap from 4 actions to 3 actions, which is a great progress in design: ① the mouse enters the cage; ② When a mouse tries to eat bait, it must first touch the pedal and start the mechanism; ③ The cage door was closed and the mouse was trapped. Reducing the traditional mouse-catching program from four actions that are easy to make mistakes to three actions that are not easy to make mistakes, although only one action is reduced, it has brought a qualitative leap and greatly improved the rat-catching rate-achieving the goal of catching rats in cages. In fact, in the face of various design schemes of pedal mousetrap, the high-sensitivity pedal mousetrap improved from the traditional mouse cage should be given priority. Because the traditional squirrel cage has a wide mass base and a high penetration rate. The improved high-sensitivity pedal mousetrap is very similar to the traditional mousetrap. When promoting products, customers can easily master the use method, which reduces the tedious explanation work after new products are put on the market. Comparatively speaking, it is the product with the simplest structure, the most advantages and the lowest cost among all kinds of pedal mousetraps. In order to make a better mousetrap, the production department should make great efforts to overcome the shortcomings of the traditional mousetrap, and make the new mousetrap become an excellent product with beautiful appearance, superior performance, elite and practical, neat mesh, flat bottom and mice willing to enter. Set strict quality requirements for products: First, in order to make rats willing to enter, put them on a horizontal plane, and overcome the shortcomings that the bottom of the cage is quadrangular, it is difficult to put fat, and the rats will retreat because of the shaking of the cage after entering. The gauze at the bottom of the cage should be smooth, and there should be no obstacles in front of the cage, at the mouth of the cage and at the bottom of the cage that affect the entry of mice. The height between the front part of the cage bottom and the mouse entrance is less than 4.5 mm; ; Secondly, in order to make the smallest mouse unable to escape, the requirements for cage holes must be strict, and galvanized welded mesh with uniform mesh size less than 8mm should be selected; Third, improve the accuracy of parts, and the surface and corners of products should be smooth and burr-free. For parts with movable parts, the joints are required to be firm and flexible. The elasticity of the door closing spring is small, which makes the product a very safe and environmentally friendly product; The four pedals should be sensitive enough, and the cage door will be closed and locked as long as the mouse, big or small, touches it after entering. The door lock should be sensitive and firm, so that the caught mouse can never escape; 5. Improve productivity, apply modern technology as much as possible, and make products cheap and durable. In order to meet the needs of different levels of people, we should also design rat cages with different performances: First, in order to facilitate researchers to do experiments and trick more mice, after the cage door is opened, we should add new products that can change the performance of rat cages at any time. Therefore, the mouse cage can be used as a mouse trap at any time; You can also turn it into a mousetrap at will. Namely: ① When the cage door is opened, bait is put in, and there is no supporting mechanism, the rat cage is in a trapping state where rats can freely enter and exit at any time, eat bait safely and leave the trap cage safely; (2) Open the cage door, put the bait and set up the mechanism, and the rat cage will be in a state of high alert-as long as the mouse enters the cage, immediately close the cage door and lock it. The second is to develop a product that rats can't escape even if the cage is overturned or inverted, so as to meet the needs of catching rats in the wild or in pet families. Third, develop a double-door mousetrap that is more deceptive and makes the "mouse king" who has a strong reaction to "new things" easy to be deceived. Fourthly, in order to facilitate researchers to use live mice, a mousetrap is added, which can transfer or concentrate mice at any time according to people's will. Making a mouse trap with superior performance is the core of developing an instrument mouse trap, and it is also a technical preparation for exploring the secrets of the mouse kingdom. At present, because there is no new breakthrough in mousetrap technology, pedal mousetrap is an ideal product to catch live mice. It seems that it is time for the pedal squirrel cage to replace the traditional squirrel cage.
