Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, and in particular to a pressure sensor with a guide wheel. Background Technology

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable electrical signals according to certain rules. Pressure sensors are one of the most commonly used sensors in industrial practice and are widely used in various industries.

[0003] Existing pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. When pressure sensors are used in the wire winding process, they are required to sense the tension of the wire. However, existing pressure sensors are standalone devices, requiring the addition of guide wheels on the winding equipment so that the wire tension can act on the pressure-sensitive element of the pressure sensor. The additional guide wheels not only affect the tension of the wound wire but also easily affect the accuracy of the pressure sensor in sensing the wire tension. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-4 The pressure sensor with guide wheel shown includes:

[0033] The pressure sensor body 1 includes an annular sensitive element 3, which is used to sense external pressure. The annular sensitive element 3 has an annular structure and is a sensitive element whose electrical parameters change with the change of external pressure. A metal sensing diaphragm is provided on the outer wall of the annular sensitive element 3. Under external pressure, it can complete the information conversion function by changing the resistance value, thereby realizing pressure sensing.

[0034] The annular sensitive element 3 is provided with a guide mechanism 4. The guide mechanism 4 includes a guide wheel body 41, a bearing 42 and multiple adjustment components 43. The guide wheel body 41 is sleeved on one end of the pressure sensor body 1 and on the outside of the annular sensitive element 3. The bearing 42 is fixed between the guide wheel body 41 and the pressure sensor body 1. By setting the bearing 42, the guide wheel body 41 can be stably rotated at one end of the pressure sensor body 1, so that the guide wheel body 41 can be used as a line guide.

[0035] Multiple adjustment components 43 are arranged in a ring array on the inner wall of the guide wheel body 41. The adjustment components 43 are used for the elastic support of the line. The multiple adjustment components 43 are arranged in a ring array and are attached to the outer wall diaphragm of the ring sensitive element 3.

[0036] The adjustment assembly 43 includes: a bearing structure 431, a compression spring 432, a positioning groove 433, a pressure rod 434, and multiple limiting blocks 435. The positioning groove 433 is composed of two circular grooves with different diameters. The multiple bearing structures 431 are arranged in a ring array in the middle of the guide wheel body 41. The bearing structure 431 is used to guide the line to fit against the guide wheel body 41. The bearing structure 431 includes a bearing block 4311 and an elastic block 4312. The bearing block 4311 is fixed to one end of the pressure rod 434 and is slidably connected to the inner wall of the guide wheel body 41. The elastic block 4312 is fixed to the outer wall of the bearing block 4311. The elastic block 4312 is made of rubber and its outer wall fits against the inner wall of the guide wheel body 41. The elastic block 4312 prevents the wound line from getting stuck in the inner cavity of the guide wheel body 41, so that the line can move stably between the multiple bearing blocks 4311 and the inner cavity of the guide wheel body 41.

[0037] A compression spring 432 is disposed on the outer wall of the bearing structure 431. One end of the compression spring 432 is fixedly connected to the outer wall of the bearing block 4311, and the other end of the compression spring 432 is fixedly connected to the inner wall of the positioning groove 433. The elasticity of the compression spring 432 facilitates elastic pushing of the bearing block 4311, resulting in a circle with different diameters formed by multiple bearing blocks 4311. This allows for a certain degree of tension adjustment of the guide line, preventing it from becoming too taut and breaking. Multiple positioning grooves 433 are arranged in a ring array in the middle of the guide wheel body 41. A pressure rod 434 is sleeved in the inner cavity of the compression spring 432 and is used to press the annular sensitive element 3. Multiple pressure rods... The rods 434 are arranged in a ring array and are slidably inserted into the inner wall of the guide wheel body 41. When the lines are guided in the inner cavity of the guide wheel body 41, the lines are pressed against the inner wall of the bearing block 4311. When lines with different tensions are pressed against the inner wall of the bearing block 4311, one end of the pressure rod 434 applies different degrees of pressure to the outer wall of the ring sensitive element 3, which facilitates the tension sensing of lines with different tensions. Two adjacent limit blocks 435 are fixedly connected to one end of the inner wall of the positioning groove 433. Multiple limit blocks 435 are slidably inserted into the outer sides of the pressure rod 434 respectively. The stability of the position of the pressure rod 434 is improved by the limit blocks 435.

[0038] The annular sensitive element 3 is fixedly inserted into one end of the pressure sensor body 1. A fixing nail 2 is fixedly connected to one end of the pressure sensor body 1. The top cap of the fixing nail 2 is snapped into one end of the guide wheel body 41, which facilitates the reinforcement of the position of the guide wheel body 41.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
