Description

Technical Field

[0001] This utility model relates to the field of bellows sensor technology, and in particular to a high-precision, high-speed sensor. Background Technology

[0002] A bellows sensor is a device that uses the elastic deformation characteristics of a bellows to measure physical quantities. It is commonly used for detecting parameters such as pressure and displacement. Bellows sensors are characterized by their simple structure, high sensitivity, and adaptability to a certain temperature range. They are widely used in industrial automation, hydraulic systems, and instrumentation. Their core component is the bellows. When subjected to external pressure or displacement, the bellows expands or deforms. This deformation is transmitted to a conversion element through its internal mechanical structure, which then converts the physical quantity into a measurable electrical signal, enabling the quantitative detection of the measured parameter. Figure 4 As shown, existing bellows sensors typically employ a dual-hole parallel beam structure design. This dual-hole parallel beam structure is a traditional static structure and is not suitable for high-speed dynamic applications. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a high-precision high-speed sensor, comprising: a sensor body 1, a parallel groove 2 formed on the surface of the sensor body 1, an H-shaped crossbeam 3 installed on the inner wall of the parallel groove 2, a corrugated pipe body 4 installed on the surface of the sensor body 1, and a connecting wire 5 installed at one end of the sensor body 1.

[0021] Specifically: When the device is first used, the parallel groove 2 opened on the surface of the sensor body 1 makes the sensor body 1 form a parallel beam structure. Then, the H-shaped crossbeam 3 installed on the inner wall of the parallel groove 2 changes the traditional double-hole parallel beam structure of the bellows sensor to an H-beam plus parallel beam structure, so that the sensor can respond more quickly. The bellows body 4 is installed on the surface of the sensor body 1 and is covered by the parallel groove 2 and the H-shaped crossbeam 3 for protection, making the device more complete.

[0022] In one embodiment, a connecting nut 6 is installed at one end of the sensor body 1, a connecting screw 7 is threaded into the inner wall of the connecting nut 6, a connector 8 is installed at one end of the connecting screw 7, a protective spring 9 is installed at the other end of the connector 8, and the surface of the connecting wire 5 is embedded in the inner wall of the connecting screw 7, the connector 8 and the protective spring 9.

[0023] Specifically: When the device is in use, the connecting wire 5 is installed on the inner wall of the connecting screw 7, the connector 8, and the protective spring 9. Then, the connecting screw 7 is installed on the connecting nut 6 installed at one end of the sensor body 1, so that the connecting wire 5 is connected to the sensor body 1. Then, the protective spring 9 installed at the other end of the connector 8 protects the connecting wire 5 from bending and prevents damage caused by bending after the connecting wire 5 is connected to the sensor body 1, making the device more perfect.

[0024] In one embodiment, a limiting groove 10 is installed on the surface of the connecting wire 5, and a limiting piece 11 is provided on the inner wall of the connector 8, with the surface of the limiting groove 10 installed on the inner wall of the limiting piece 11.

[0025] Specifically: The limiting groove 10 installed on the surface of the connecting line 5 is mounted on the inner wall of the limiting plate 11. When the connecting screw 7 installed at one end of the connector 8 is installed into the inner wall of the connecting nut 6, the connecting screw 7 is installed into the inner wall of the connecting nut 6 by rotating the connector 8. When the connector 8 is rotated, the connecting line 5 will not rotate, which prevents the connecting line 5 from being connected to the sensor body 1, thus making the device more perfect.

[0026] Working Principle: During use, the parallel grooves 2 on the surface of the sensor body 1 create a parallel beam structure. Then, the H-shaped crossbeam 3 installed on the inner wall of the parallel grooves 2 changes the traditional double-hole parallel beam structure of the bellows sensor to an H-beam plus parallel beam structure, allowing for faster response and better suitability for high-speed dynamic applications. The bellows body 4, mounted on the surface of the sensor body 1, protects the parallel grooves 2 and H-shaped crossbeam 3, further enhancing the device's functionality. During operation, the connecting wire 5 is installed on the inner wall of the connecting screw 7, connector 8, and protective spring 9. Then, the connecting screw 7 is... The connecting nut 6 is installed on one end of the sensor body 1 to connect the connecting wire 5 to the sensor body 1. Then, the protective spring 9 installed on the other end of the connector 8 protects the connecting wire 5 from bending and damage caused by bending after it is connected to the sensor body 1. The limiting groove 10 installed on the surface of the connecting wire 5 is installed on the inner wall of the limiting plate 11. When the connecting screw 7 installed on one end of the connector 8 is installed into the inner wall of the connecting nut 6, the connecting screw 7 is installed into the inner wall of the connecting nut 6 by rotating the connector 8. The connecting wire 5 will not rotate when the connector 8 is rotated, so as to prevent the connecting wire 5 from being connected to the sensor body 1, thus making the device more perfect.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
