The utility model relates to the technical field of scales, in particular to a scale foot structure and a scale with the scale foot structure.

Background art:

Weighing scale is generally composed of three parts: bearing system, force transmission system and display system.

The working principle of electronic scale is: when an object is placed on the scale, pressure is applied to the sensor, and the sensor is elastically deformed, so that the impedance changes, and at the same time, the excitation voltage changes, and the changed analog signal is output; The signal is amplified by the amplifier circuit and output to the analog-to-digital converter; Converted into a digital signal which is convenient for processing and output to the cpu for operation control, and the CPU outputs the result to the display according to the received digital signal.

The existing scale foot structure of weighing scale mostly fixes the sensor through the buckle structure, that is, a plurality of buckle structures are arranged around the installation groove of the shell. In the installation process, the sensor can only be installed in the installation groove after each buckle is extruded and deformed, so that each buckle is easy to deform and fail, resulting in the sensor being not firmly fixed and falling off.

Technical realization elements:

The utility model aims to provide a scale foot structure to solve the problem that the existing scale sensor is not firmly installed and is easy to fall off.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a scale foot structure comprises a sensor and a shell for fixing the sensor, wherein the shell comprises a fixed cavity and a waiting cavity communicated with the fixed cavity; the side wall of the fixed cavity protrudes horizontally outward to form a plurality of gusset plates arranged at intervals, and the horizontal height of each gusset plate is the same; the bottom of the waiting cavity is provided with a retaining arm, and one end of the retaining arm is connected with the bottom of the waiting cavity. The other end of the retaining arm extends to the fixed cavity and warps outward away from the bottom of the waiting cavity; When the sensor slides into the fixed cavity from the waiting cavity, each buckling plate is buckled with the top end surface of the sensor; When the sensor slides into the fixed cavity from the waiting cavity, the blocking arm abuts against the side end face of the sensor.

Specifically, the blocking arm comprises a body, and one end of the body far from the bottom of the waiting cavity is flush with the height of the sensor in the vertical direction.

Preferably, the end of the main body far from the bottom of the waiting chamber protrudes downward in the vertical direction to form a baffle.

Further, the scale foot structure also comprises a support foot assembly, and the support foot assembly covers the sensor and is connected to the shell.

Specifically, the supporting foot assembly comprises an elastic foot, which comprises a main body for contacting the ground, a fixing ring surrounding the main body and a plurality of connecting arms connecting the main body and the fixing ring, wherein the fixing ring has a plurality of mounting holes, and the shell has a plurality of mounting posts, each mounting hole is mounted on a corresponding mounting post, and the main body abuts against the sensor.

Specifically, the supporting foot assembly further comprises a cushion block, wherein the main body is provided with an installation groove, and the cushion block is placed in the installation groove and abuts against the sensor.

Specifically, the supporting foot assembly further comprises a foot protection shell, and the foot protection shell covers the main body.

The utility model has the beneficial effects that the use process of the scale foot structure of the utility model is as follows: firstly, the sensor is placed in the waiting cavity, and the retaining arm is squeezed to keep the retaining arm straight in the deformed state; Secondly, the sensor slides into the fixed cavity from the waiting cavity. At this time, the blocking arm that has lost the pressing force returns to the initial state and abuts against the side end face of the sensor to prevent the sensor from sliding into the waiting cavity again. At the same time, each buckle plate in the fixed cavity is buckled on the top end surface of the sensor to prevent it from coming out of the fixed cavity, that is, the installation action is completed. Finally, the user presses the retaining arm to the horizontal state again, and the sensor that has lost its abutting function can retreat from the fixed cavity to the waiting cavity in the horizontal direction, that is, the disassembly action is completed. The sensor in the scale foot structure is simple to assemble and disassemble, easy to operate, and the freedom of movement of the sensor is limited from the horizontal and vertical directions, so the fixation is more firm and not easy to loosen.

The embodiment of the utility model also provides a scale, which comprises the scale foot structure.

Please refer to Figure 1 to Figure 3. The scale foot structure 100 provided by the embodiment of the utility model comprises a sensor 10 and a shell 20 for fixing the sensor 10. The housing 20 includes a fixed chamber 20a and a waiting chamber 20b communicating with the fixed chamber 20a, and the side wall of the fixed chamber 20a protrudes horizontally outward to form a plurality of gusset plates arranged at intervals. The bottom of the waiting chamber 20b is provided with a blocking arm 22, one end of which is connected to the bottom of the waiting chamber 20b, and the other end of which extends toward the fixed chamber 20a and bends outward in a direction away from the bottom of the waiting chamber 20b. When the sensor 10 slides into the fixing cavity 20a from the waiting cavity 20b, each pinch plate 2 1 0 is buckled on the top end face of the sensor 10, and when the sensor 10 slides into the fixing cavity 20a from the waiting cavity 20b, the blocking arm 22 abuts against one end face of the sensor 10. Here, it can be understood that the sensor 10 is a block having a top end face, a bottom end face and a side end face. When the sensor 10 is placed in the fixed cavity 20a, its top end faces outward and its bottom end faces inward, and the side end face of the sensor 10 corresponds to the side wall of the fixed cavity 20a. At this time, each pinch plate 2 1 is buckled on the top end surface of the sensor 10, and the sensor 10 falls off from the fixing cavity 20a. At the same time, the blocking arm 22 abuts against the side end face of the sensor 10, thereby preventing the sensor 10 from sliding back into the waiting cavity 20b, that is, the sensor 10 is confined in the fixed cavity 20a by the pinch plate 2 1 and the blocking plate.

The use process of the scale foot structure 100 provided by the embodiment of the utility model is as follows: firstly, the sensor 10 is placed in the waiting cavity 20b, and the retaining arm 22 is squeezed to keep it straight in the deformed state; Secondly, the sensor 10 slides into the fixed cavity 20a from the waiting cavity 20b. At this time, the blocking arm 22, which has lost the pressing force, returns to the initial state and abuts against the side end face of the sensor 10 to prevent the sensor 10 from sliding into the waiting chamber 20b again. At the same time, each pinch plate 2 1 in the fixed chamber 20a is buckled on the sensor 65438+. Finally, the user presses the barrier arm 22 to the horizontal state again, and the sensor 10 that has lost its abutting function can be withdrawn from the fixed cavity 20a to the waiting cavity 20b in the horizontal direction, that is, the disassembly action is completed. The sensor 10 in the scale foot structure 100 is easy to assemble and disassemble and easy to operate. The freedom of movement of the sensor 10 is limited in both horizontal and vertical directions, so the fixation is more firm and not easy to loosen.

Preferably, in this embodiment, the sensor 10 is square, that is, it has a top end face, a bottom end face and four side end faces. Meanwhile, the matching fixing cavity 20a is also square with three side walls. At this time, the number of pinch plates 2 1 is three, and each side wall is provided with a pinch plate 2 1 respectively, so that in the vertical direction, of course, the sensor 10 can also be circular, and the matching fixing cavity 20a can also be circular. Then, three pinch plates 2 1 are respectively arranged in the 0-degree direction, 90-degree direction and 180-degree direction of the fixed cavity 20a. It can also prevent the sensor 10 from falling off. Here, the number of gusset plates 2 1 can be increased or decreased according to actual needs.

Please refer to Figure 1 to Figure 3 for details. In this embodiment, the blocking arm 22 includes a main body 22 1, and the end of the main body 22 1 far from the bottom of the waiting room 20b is vertically flush with the height of the sensor 10. Preferably, the main body 22 1 includes a first connecting section 22a, a second connecting section 22b and a transition connecting section 22c for connecting the first connecting section 22a and the second connecting section 22b. The end face of the first connecting section 22a is parallel to the housing 20, and the end face of the second connecting section 22a is flush with the end face of the sensor 10, so that the sensor 10 can be better shielded.

Preferably, please refer to Figure 1 to Figure 3. In this embodiment, an end of the main body 22 1 far from the bottom of the waiting room 20b protrudes downward in the vertical direction to form a spacer 222. It can be understood that the function of the cushion block 222 is to increase the contact area between the body 22 1 and the sensor 10, that is, in the vertical direction, the sum of the thickness of the body 22 1 and the cushion block 222 is greater than or equal to the thickness of the sensor 10, so that the sensor 10 is not easy to be detached from the fixation in a large vibration environment.

Please refer to Figure 1 and Figure 3 for details. In this embodiment, the scale foot structure 100 further includes a support foot assembly 30, which covers the sensor 10 and is connected to the housing 20. Here, the function of the supporting foot assembly 30 is to realize the indirect contact between the sensor 10 and the supporting ground, that is, when in use, the supporting foot assembly 30 first deforms and then acts on the sensor 10, so that the sensor 10 generates data and transmits it to the processor.
