DETAILED DESCRIPTION

[0023] There are many existing methods for fixing and installing pressure sensors. When installing pressure sensors, they are generally fixed or plugged in by bolts. When performing pressure tests on pressure sensors, they need to be quickly disassembled and installed to increase the testing efficiency of the pressure sensors. Therefore, a snap-on, disassembled pressure sensor fixing method is needed.

[0024] like Figure 1-Figure 2 As shown, the device includes a test bench 1, which is composed of a mounting assembly 2 and a limiting assembly 3. A clamping groove 101 is provided on the top of the test bench 1, and the clamping groove 101 can clamp and place the pressure sensor. The pressure sensor is clamped and fixed on the top of the test bench 1 by the mounting assembly 2, and the limiting assembly 3 limits and fixes the side of the pressure sensor. The pressure sensor is clamped inside the clamping groove 101 on the top of the test bench 1 for preliminary installation.

[0025] First, the specific structure of the installation component 2 is disclosed. The installation component 2 includes a mounting groove 201. A spring 202 is installed at the bottom of the inner wall of the mounting groove 201. A connecting plate 203 is installed on the top of the spring 202. A sliding group 204 is arranged outside the connecting plate 203. The connecting plate 203 can be pulled up and down by the sliding group 204 with the help of the spring 202 and then rebound. A damping shaft 205 is rotatably installed on the top of the connecting plate 203. A clamping block 206 is installed on the outer side of the damping shaft 205. The damping shaft 205 can drive the clamping block 206 to rotate at different angles. The sliding group 204 includes a sliding groove 2041. A slider 2042 is installed inside the sliding groove 2041. The sliding groove 2041 is opened on the inner wall of the mounting groove 201. The slider 2042 is fixedly installed on the outer surface of the connecting plate 203. The connecting plate 203 slides up and down through the slider 2042. The spring 202 can generate a pulling force on the upward moving connecting plate 203.

[0026] When the pressure sensor is clamped and fixed, a mounting groove 201 is opened on the top of the test bench 1, and a spring 202 is installed at the bottom of the inner wall of the mounting groove 201. The other end of the spring 202 is installed inside the connecting plate 203. Four sliding grooves 2041 are opened on the side wall of the mounting groove 201. Four sliders 2042 in the four sliding grooves 2041 can be fixedly connected to the side of the connecting plate 203, so that when the connecting plate 203 moves upward with the help of the sliders 2042, the spring 202 can provide downward pressure to the connecting plate 203. Pulling force, when the pressure sensor is snapped into the inside of the snap-in groove 101, the damping shaft 205 on the top of the connecting plate 203 rotates an angle, so that the snap-in block 206 rotates to other angles without affecting the snap-in of the pressure sensor. After the pressure sensor is snapped, the damping shaft 205 is pulled upward and rotated, so that the snap-in block 206 can follow the rebound of the connecting plate 203 to snap-in and fix the top of the pressure sensor, thereby achieving the effect of snap-in and fixing the pressure sensor. The structure is simple and the pressure sensor can be quickly disassembled and installed.

[0027] The improvement of this embodiment is that the pressure sensor is fixed by the spring 202, the connecting plate 203 and the clamping block 206 structure, which solves the problem of the pressure sensor being difficult to disassemble after installation in the prior art.

[0028] Since the mounting assembly 2 in the prior art is used to clamp and fix the top of the pressure sensor, and the side is not limited, Figure 2 A second embodiment of the present utility model is shown.

[0029] The specific structure of the limit assembly 3 is disclosed again. The limit assembly 3 includes a rotating shaft 301. The outer surface of the rotating shaft 301 can be rotatably mounted with a limit plate 302. The limit plate 302 can be rotated by the rotating shaft 301 to limit the pressure sensor in the clamping groove 101. The limit plate 302 can be rotated by the rotating shaft 301. After the pressure sensor is clamped into the clamping groove 101, the limit plate 302 is rotated to block and limit the side of the pressure sensor, so as to achieve the effect of clamping and fixing the side of the pressure sensor. The limit plate 302 can be removed by rotation, which is convenient for installing and removing the pressure sensor.

[0030] The improvement of this embodiment is that the side of the pressure sensor is clamped and fixed by the limiting plate 302 structure, which solves the problem of easy displacement of the side of the pressure sensor in the prior art without limiting.

[0031] Considering how the clamping block 206 and the limiting plate 302 are mounted on the test bench 1 in the first and second embodiments, the pressure sensor is clamped and fixed. Figure 1The embodiment is shown as follows: the installation slot 201 is opened at the top of the test bench 1, the bottom of the clamping block 206 is set at the top of the clamping slot 101, the bottom of the clamping block 206 is attached to the top of the pressure sensor for clamping and fixing, a notch is opened on the side of the test bench 1, and the rotating shaft 301 is rotatably installed inside the notch. Four clamping blocks 206 are provided, and the four clamping blocks 206 are located at the top of the clamping slot 101 and distributed in a rectangular array.

[0032] One end of the clamping block 206 extends to the top of the clamping slot 101. After the four clamping blocks 206 clamp the pressure sensor in the clamping slot 101, the top of the pressure sensor can be clamped and fixed at four places, making the fixation more secure. The rotating shaft 301 is rotatably installed in the groove opened on the side of the clamping slot 101, so that the limiting plate 302 can be rotated to limit and fix the side of the pressure sensor in the clamping slot 101.

[0033] In summary, the working principle of this solution is as follows:

[0034] When the pressure sensor is clamped to the inside of the clamping groove 101, the damping shaft 205 on the top of the connecting plate 203 rotates an angle, so that the clamping block 206 rotates to other angles without affecting the clamping of the pressure sensor. After the pressure sensor is clamped, the damping shaft 205 is pulled upward and rotated, so that the clamping block 206 can follow the rebound of the connecting plate 203 to clamp and fix the top of the pressure sensor, thereby achieving the effect of clamping and fixing the pressure sensor. The structure is simple and the pressure sensor can be quickly disassembled and installed;

[0035] The limit plate 302 can be rotated by the rotation shaft 301. After the pressure sensor is clamped into the clamping groove 101, the limit plate 302 rotates to block and limit the side of the pressure sensor, thereby achieving the effect of clamping and fixing the side of the pressure sensor. The limit plate 302 can be removed by rotating, which is convenient for installing and removing the pressure sensor.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
