Description

Technical Field

[0001] The utility model relates to the technical field of sensor pressure heads, in particular to a sensor pressure head with stable connection. Background Technique

[0002] A sensor is a detection device that can sense the information to be measured and transform the sensed information into an electrical signal or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control, etc. It is widely used, and there are also many types of sensors, including infrared sensors, position sensors, pressure sensors, temperature sensors, tensile sensors, etc. Among them, when pressure sensors and tensile sensors are used, pressure heads are required for cooperation.

[0003] For example, patent number CN202322804015.0 discloses a pressure sensor structure, including a snap-fitting upper cover body and a lower housing. Among them: the top of the lower housing is open and a chamber is formed inside, and an air vent joint protrudes outward on the outer wall of the lower housing, and the air vent joint communicates with the chamber inside the lower housing; a flexible diaphragm is installed in the chamber of the lower housing, and the flexible diaphragm divides the chamber into upper and lower two-layer structures, and a protruding upper edge is arranged along the outer periphery of the upper surface of the flexible diaphragm; two symmetrical pressure bodies are also arranged between the upper cover body and the lower housing, and both of the two pressure bodies are arranged in contact with the upper edge on the flexible diaphragm. A first contact piece and a second contact piece are arranged on one of the pressure bodies in a vertically spaced manner in the direction of the other pressure body, and a third contact piece is arranged on the other pressure body. A downward bending part is formed at the front part of the third contact piece, and the bending part is fixedly connected to the flexible diaphragm through a pin body, and the head end of the third contact piece is located between the first contact piece and the second contact piece; connection conductors are also fixed outside the two pressure bodies, and the two connection conductors extend outward from both sides of the lower housing respectively. The pressure sensor structure of the utility model is compact. Different from the traditional pressure sensor structure composed of a magnetoresistive element and a Hall element, this pressure sensor drives the third contact piece to contact the first contact piece or the second contact piece by setting a flexible diaphragm that can sense the change of air pressure in the chamber and deform, and the external data acquisition device collects the pressure change on the first contact piece or the second contact piece, so as to complete the work of pressure measurement; this pressure sensor has the characteristics of small size, light weight, low cost, low power consumption, and high reliability;

[0004] The sensor indenter with stable connection in this patent lacks a positioning mechanism before installation, resulting in the wrong connection position between the sensor indenter and the sensor after the sensor is installed, and it is not convenient to disassemble and replace in time and quickly after use. When the indenter and the sensor are connected, a threaded screw is directly used for connection, and in the process of pulling, it is easy to get stuck or have a stripped thread, which not only affects the stability of detection, but also affects subsequent use, bringing inconvenience to users.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a sensor indenter with stable connection, including a sensor body 1. A sensor connector 4 is provided at the top end of the sensor body 1. Three connecting blocks 3 are evenly provided on the inner wall of the sensor body 1 at the bottom end of the sensor connector 4. A positioning groove 7 is provided at the bottom end of the sensor connector 4. The width of the bottom surface of the positioning groove 7 is the same as the width of the connecting block 3. The connecting block 3 is an L-shaped connecting block. A limiting block 11 is provided on the inner wall of the connecting block 3. One end of the limiting block 11 is provided with a limiting hole 6 inside the sensor connector 4. The shapes and sizes of the limiting block 11 and the limiting hole 6 are the same. The limiting block 11 passes through the limiting hole 6 and fits with the inner wall of the sensor body 1. Thus, when the sensor connector 4 is inserted into the inside of the sensor body 1, the three connecting blocks 3 are snapped into the positioning groove 7 at the bottom end of the sensor connector 4, so that the three ends of the bottom surface of the sensor connector 4 are fixed through the three connecting blocks 3, improving the stability between the sensor connector 4 and the sensor body 1;

[0026] The bottom end of the connecting block 3 penetrates through the sensor body 1 and extends to the outside of the sensor body 1. An activity groove 5 is provided on the inner side of the sensor body 1 at the bottom end of the connecting block 3. The connecting block 3 passes through the activity groove 5 and extends to the outside of the sensor body 1.

The transmission gear 9 is in transmission connection with the connecting block 3 and the transmission ring 8 through the gears respectively. Thus, by rotating the rotating ring 2 outside the sensor body 1, the three transmission gears 9 are driven to rotate together during the rotation of the rotating ring 2, so that the connecting block 3 displaces inside the sensor body 1, facilitating the fixation of the sensor connector through the connecting block 3;

[0027] A rotating ring 2 is provided on the outer side of the sensor body 1 at the bottom end of the connecting block 3. An insertion block is provided at the bottom end of the transmission ring 8.

One end of the insertion block penetrates through the rotating groove and extends to the rear end of the rotating ring 2. The transmission ring 8 and the rotating ring 2 are of an integral structure. Therefore, due to the integral structure of the transmission ring 8 and the rotating ring 2, it is convenient that when the rotating ring 2 rotates, the rotating ring 2 drives the transmission ring 8 to rotate.

[0028] During operation, first rotate the rotating ring 2. The rotating ring 2 drives the three connecting blocks 3 to retract into the interior of the sensor body 1 through the transmission ring 8. When the sensor connector 4 is inserted into the inner side of the sensor body 1, the three connecting blocks 3 on the inner side of the sensor body 1 are snapped into the positioning grooves 7 at the bottom end of the sensor connector 4, so as to perform positioning connection through the positioning grooves 7 at the bottom end of the sensor connector 4 and the three connecting blocks 3. Then, rotate the rotating ring 2 in the reverse direction. By rotating the rotating ring 2, the three connecting blocks 3 are driven to extend outward from the sensor body 1 through the transmission ring 8. A limiting block 11 is provided on the inner wall of the connecting block 3. One end of the limiting block 11 is provided with a limiting hole 6 on the inner side of the sensor connector 4. The limiting block 11 penetrates through the limiting hole 6 and fits against the inner wall of the sensor body 1. The three connecting blocks 3 fix the three ends of the bottom surface of the sensor connector 4, improving the stability of the sensor connector 4 and the sensor body 1.
