Description

Technical Field

[0001] The utility model relates to the technical field of force measuring sensor groups, and specifically relates to a force measuring sensor group. Background Art

[0002] A force measuring sensor group is composed of three major parts: one or more elastic bodies that can generate deformation after being stressed, a bridge circuit composed of resistance strain gauges that can sense this amount of deformation, and an adhesive that can fix and paste the resistance strain gauges on the elastic body and a sealant that can conduct the amount of strain to protect the electronic circuit.

[0003] For example, a flat force measuring sensor group with the authorization announcement number of "CN218724922U". The force measuring sensor group is short in height and can be used in sensor applications with small space height requirements. There are many force measuring sensor groups, which can meet the force measuring requirements of multiple workstations at the same time. The strain gauges of a single force measuring sensor are pasted on one side, reducing the overall height of the sensor group and facilitating the adjustment of angular difference. The sensors are integrally designed, saving installation space and being convenient to use. However, during the use of the force measuring sensor group, the position of the detection end cannot be adjusted, while the specifications of the detection parts change at any time. This easily causes the detection end on the side to be blocked by the detection part, reducing the detection positions of the force measuring sensor group and affecting the normal use of the force measuring sensor group, thus reducing the working efficiency of the force measuring sensor group. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of affecting the normal use of the force measuring sensor group and reducing the working efficiency of the force measuring sensor group, and to propose a force measuring sensor group.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design a force measuring sensor group, including a bracket and a chute. Chutes are respectively processed on the front and rear sides of the bracket. An adjustment structure is connected to the inner wall of the bracket. A force measuring sensor is connected to the inner wall of the adjustment structure. Bases are respectively fixedly connected to the four corners of the bottom of the bracket. Square plates are respectively fixedly connected to the bottoms of the left and right sides of the bracket. An installation structure is connected to the inner wall of the square plate.

[0007] Preferably, the adjustment structure includes a square block and a first screw. The outer wall of the square block is slidably connected to the inner wall of the bracket. The front and rear sides of the square block are respectively fixedly connected to the inner sides of the first screw. A ring is threadedly connected to the outer wall of the first screw.

[0008] Preferably, the inner side of the outer wall of the first screw is slidably connected to the inner wall of the chute.

[0009] Preferably, the inner wall of the square block is fixedly connected to the outer wall of the force measuring sensor.

[0010] Preferably, the installation structure includes a second screw and a handle. The outer wall of the second screw is threadedly connected to the inner wall of the square plate. The top of the second screw is fixedly connected to the bottom of the handle. The bottom of the outer wall of the second screw is rotatably connected to a chassis.

[0011] Preferably, the top notch of the chassis is inserted into the outer wall of the base.

[0012] A force measuring sensor group proposed by the present utility model has the beneficial effects that: by adjusting the structure, the ring rotates outward on the outer wall of the first screw. At this time, the ring disengages from the outer wall of the bracket. Then, the first screw slides left and right on the inner wall of the chute. The first screw will drive the square block to slide left and right on the inner wall of the bracket. The square block drives the force measuring sensor to move in position, realizing position adjustment. Then, the ring rotates inward on the outer wall of the first screw, making the inner side of the ring abut against the outer wall of the bracket. The positions of the first screw, the square block, and the force measuring sensor are fixed by the friction between the ring and the bracket, ensuring the normal use of the force measuring sensor group and improving the working efficiency of the force measuring sensor group.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below with reference to the accompanying drawings:

[0020] Embodiment 1:

[0021] Please refer to Figures 1-5: In this embodiment, a force measuring sensor group includes a bracket 1 and a chute 4. Chutes 4 are processed on the front and rear sides of the bracket 1 respectively. An adjustment structure 2 is connected to the inner wall of the bracket 1, and a force measuring sensor 9 is connected to the inner wall of the adjustment structure 2. How to operate and use the force measuring sensor 9 is already prior art and will not be elaborated. The model is selected according to the usage requirements. The four corners of the bottom of the bracket 1 are fixedly connected with bases 5 respectively, and square plates 6 are fixedly connected to the bottom parts on the left and right sides of the bracket 1 respectively. An installation structure 3 is connected to the inner wall of the square plate 6.

[0022] The adjustment structure 2 includes a square block 201 and a first screw 202. The outer wall of the square block 201 is slidably connected to the inner wall of the bracket 1. The square block 201 slides left and right through the inner wall of the bracket 1 under force. The front and rear sides of the square block 201 are fixedly connected to the inner sides of the first screw 202 respectively. A ring 203 is threadedly connected to the outer wall of the first screw 202. The ring 203 rotates back and forth through the outer wall of the first screw 202 under force. The inner side of the outer wall of the first screw 202 is slidably connected to the inner wall of the chute 4. The first screw 302 slides left and right through the inner wall of the chute 4 under force. The inner wall of the square block 201 is fixedly connected to the outer wall of the force measuring sensor 9.

[0023] By rotating the ring 203 outward on the outer wall of the first screw 202 in the adjustment structure 2, at this time the ring 203 disengages from the outer wall of the bracket 1, and then the first screw 202 slides left and right through the inner wall of the chute 4. The first screw 202 will drive the square block 201 to slide left and right through the inner wall of the bracket 1, and the square block 201 drives the force measuring sensor 9 to move in position, realizing position adjustment. Then the ring 203 rotates inward on the outer wall of the first screw 202 to make the inner side of the ring 203 abut against the outer wall of the bracket 1. The positions of the first screw 202, the square block 201 and the force measuring sensor 9 are fixed by the friction between the ring 203 and the bracket 1, ensuring the normal use of the force measuring sensor group and improving the working efficiency of the force measuring sensor group.

[0024] The installation structure 3 includes a second screw 301 and a handle 302. The outer wall of the second screw 301 is threadedly connected to the inner wall of the square plate 6. The second screw 301 rotates up and down through the inner wall of the square plate 6 under force. The top of the second screw 301 is fixedly connected to the bottom of the handle 302. The handle 302 facilitates driving the second screw 301 to rotate. The bottom of the outer wall of the second screw 301 is rotatably connected to a chassis 303. The bottom of the outer wall of the second screw 301 rotates through the bearing on the top of the chassis 303 under force. The top notch of the chassis 303 is inserted into the outer wall of the base 5.

[0025] Working principle:

[0026] Fixing of the force measuring sensor group:

[0027] Make the bottom of the chassis 303 fit with the connecting surface, and then the bolt is threaded through the chassis 303 from top to bottom and fixed to the connecting surface by threading. When the installation position is a beam frame, make the handle 302 drive the second screw 301 to rotate downward through the square plate 6. The rotating second screw 301 drives the chassis 303 to move downward on the outer wall of the base 5, and then insert the chassis 303 into the outer wall of the beam frame. Then, the bolt passes through the chassis 303 and the beam frame for fixation.

[0028] Use of the force measurement sensor group:

[0029] Make the ring 203 rotate outward on the outer wall of the first screw 202. At this time, the ring 203 disengages from the outer wall of the bracket 1. Then, the first screw 202 slides left and right on the inner wall of the chute 4. The first screw 202 drives the square block 201 to slide left and right on the inner wall of the bracket 1. The square block 201 drives the force measurement sensor 9 to move in position to achieve position adjustment. Then, the ring 203 rotates inward on the outer wall of the first screw 202 to make the inner side of the ring 203 press tightly against the outer wall of the bracket 1. The friction between the ring 203 and the bracket 1 fixes the positions of the first screw 202, the square block 201, and the force measurement sensor 9. Subsequently, connect the wire at the bottom of the force measurement sensor 9 to an external display device, place the object on the top of the force measurement sensor 9, and the measurement data of the object is transmitted to the display device through the wire.

[0030] Embodiment 2:

[0031] Please refer to Figures 1-5 : In this embodiment, a force measurement sensor group further includes a vertical rod 7 and a circular plate 8. The top of the vertical rod 7 is fixedly connected to the bottom right side of the force measurement sensor 9, and the bottom of the vertical rod 7 is fixedly connected to the top of the circular plate 8.

[0032] Working principle:

[0033] The wire at the bottom of the force measurement sensor 9 can be wound around the outer wall of the vertical rod 7 for storage. At the same time, the circular plate 8 restricts the wire to prevent the wound wire from slipping and disengaging from the vertical rod 7.
