[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] The pressure sensor uses a detection device, such as Figure 1 and Figure 2 As shown, it includes a support platform 1, which is used to achieve stable support and limitation of various parts with the help of the support platform 1. A fixed limiting part is provided on the support platform 1, and a fixed detection cavity 2 is provided on the fixed limiting part, which can be against the side wall of one side of the pressure sensor. A driving limiting part is provided on the support platform 1, and a sliding detection cavity 3 is provided on the driving limiting part for placing the pressure sensor and against the side wall of the other side of the pressure sensor. The driving limiting part can slide vertically to pass into or out of the fixed detection cavity 2. With the help of the fixed detection cavity 2 and the sliding detection cavity 3, the stable limitation of the pressure sensor detection process can be achieved. At the same time, the sliding detection cavity 3 will also drive the pressure during the sliding process. The sensor is loaded, and at the same time, when the pressure sensor slides upward with the sliding detection cavity 3, it will gradually come out of the sliding detection cavity 3, making the process of users removing the pressure sensor more convenient. After the sliding detection slides away from the fixed detection cavity 2, the opening of the sliding detection cavity 3 is opened, so that the user can more conveniently place the pressure sensor into the sliding detection cavity 3, making the loading process during the pressure sensor detection process more convenient. The driving limit part is provided with a tightening member 5 which gradually presses against the pressure sensor as it slides downward. Under the action of the tightening member 5, pressure is applied to the pressure sensor, thereby achieving stable detection of the pressure sensor.

[0022] like Figure 1 and Figure 2 As shown, the drive limiting portion includes a support frame 6 fixedly connected to the top surface of the support platform 1 by welding, and a telescopic drive member 7 is fixedly connected to the support frame 6 by bolt locking, which is vertically arranged and used to drive the sliding detection cavity 3 to slide. The telescopic drive member 7 is arranged as an electric telescopic rod. The telescopic drive member 7 is used to ensure that the position of the sliding detection cavity 3 can be adjusted, thereby ensuring that the position of the pressure sensor placed in the sliding detection cavity 3 can be adjusted.

[0023] like Figure 2-Figure 4As shown, the driving end of the telescopic driving member 7 is fixedly connected to the vertically arranged sliding arc piece 8 by welding, the sliding detection cavity 3 is located at the concave surface of the sliding arc piece 8, and the support platform 1 is provided with a first makeshift groove 9 for the sliding arc piece 8 to penetrate and slide. The fixed limiting portion includes a fixed arc piece 10 fixedly connected to the top surface of the support platform 1 by welding and arranged vertically, the fixed detection cavity 2 is located at the concave surface of the fixed arc piece 10, and the concave surface of the fixed arc piece 10 is opposite to the concave surface of the sliding arc piece 8. An observation groove 11 is opened horizontally on the fixed arc piece 10, and the observation groove 11 is filled with a transparent sheet 12. The transparent sheet 12 is set to glass material. The operator can use the transparent sheet 12 and the observation groove 11 to observe the pressure sensors placed in the fixed detection cavity 2 and the sliding inspection cavity, so that the detection process of the pressure sensor is more convenient.

[0024] like Figure 2-Figure 4 As shown, a second give way groove 13 arranged vertically is provided on the fixed arc piece 10, and a sliding plate 14 that slides vertically is provided in the second give way groove 13, and the groove wall of the second give way groove 13 is abutted against the side walls on both sides of the width direction of the sliding plate 14. The second give way groove 13 is used on the one hand to provide a give way effect for the sliding process of the sliding plate 14, ensuring that the sliding plate 14 can slide in the second give way groove 13, and on the other hand, the second give way groove 13 is abutted against the side walls of the sliding plate 14 to achieve stable guidance and limitation of the sliding process of the sliding plate 14, ensuring that the sliding process of the sliding plate 14 is more stable. A fixed plate 15 facing the sliding plate 14 is fixedly connected to the inner top surface of the second give way groove 13 near the top by welding, and the sliding plate 14 is fixedly connected to the inner top surface of the second give way groove 13 by welding. The sliding rod 16 is fixedly connected with the fixed plate 15 in a vertical direction and slidably connected to the fixed plate 15. The sliding between the sliding rod 16 and the fixed plate 15 realizes the stable guidance and limiting effect on the sliding process of the sliding plate 14, ensuring that the sliding process of the sliding plate 14 is smoother. The sliding rod 16 is provided with a spring 17 at both ends of which are respectively against the fixed plate 15 and the sliding plate 14. The top of the sliding rod 16 is fixedly connected with a limiting block 18 by welding. The limit block 18 is provided to achieve stable limiting of the position of the sliding rod 16. The spring 17 is squeezed to perform elastic deformation when the sliding plate 14 slides upward. When the force applied to the sliding plate 14 is withdrawn, the sliding plate 14 is pushed to reset under the action of the elastic force generated by the elastically deformed spring 17.

[0025] like Figure 2-Figure 4 As shown, a circular plate 19 is fixedly connected to the sliding plate 14 on the side close to the fixed arc piece 10 by welding, and the concave surface of the fixed arc piece 10 and the concave surface of the sliding arc piece 8 are covered on the peripheral wall of the circular plate 19. With the help of the circular plate 19, the pressure sensor can be stably placed and limited, and then with the help of the joint action of the fixed arc piece 10 and the sliding arc piece 8, the pressure sensor can be stably limited, and then the stable detection of the pressure sensor can be achieved.

[0026] like Figure 2-Figure 4 As shown, the top of the sliding arc piece 8 is fixedly connected to the connecting rod 20 by welding, the fastening member 5 is vertically arranged and threadedly connected to the connecting rod 20, the fastening member 5 is arranged as a screw, the central axis of the fastening member 5 coincides with the central axis of the circular plate 19, and the top of the fastening member 5 is fixedly connected to the knob by adhesive. The setting of the knob allows the user to better apply force to the fastening member 5 with the help of the knob, and then with the help of the threaded connection between the fastening member 5 and the connecting rod 20, the position of the fastening member 5 can be stably adjusted, so that the overall structure can better adapt to the detection of the pressure sensor.

[0027] Working principle: Place the pressure sensor in the sliding detection chamber 3, start the telescopic drive member 7, and the driving end of the telescopic drive member 7 moves to drive the driving limit part to move downward. During this process, the circular plate 19 will be against the table surface of the support platform 1, and the peripheral wall of the pressure sensor will be against the concave surfaces of the fixed arc plate 10 and the sliding arc plate 8. The sliding arc plate 8 will penetrate into the first give way groove 9 for sliding. At the same time, the sliding plate 14 will gradually approach the fixed plate 15 and squeeze the spring 17 for elastic deformation. During this process, the clamping member 5 will gradually approach the pressure sensor and pressurize the pressure sensor to realize the detection of the pressure sensor. When the pressure sensor is detected, the telescopic drive member 7 is started to drive the sliding arc plate 8 to reset. During this process, the spring 17 will gradually reset and push the circular plate 19 away from the clamping member 5, so that the opening of the sliding detection chamber 3 gradually opens, which is convenient for the operator to remove the pressure sensor from the sliding detection chamber 3 and replace it with a new pressure sensor.
