[0027] The mounting assembly 3 includes a connecting groove 301, the inner wall of the connecting groove 301 is snap-connected with a connecting block 302, one side of the connecting block 302 is provided with a positioning groove 303, and the inner wall of the positioning groove 303 is snap-connected with a positioning rod 304, a screw rod 305 is installed inside the mounting plate 1, and the outer surface of the screw rod 305 is threadedly connected with a moving plate 306, and the inner wall of the moving plate 306 is slidably connected with a sliding rod 307;

[0028] The adjustment component 6 includes a motor 601, the output end of the motor 601 is detachably connected to a screw rod 602 via a coupling, and the outer surface of the screw rod 602 is threadedly connected to a moving block 603, a first rotating shaft 604 is installed at the bottom of the moving block 603, and a movable rod 605 is rotatably connected to the bottom of the first rotating shaft 604, and a second rotating shaft 606 is installed at the bottom of the movable rod 605.

[0029] Through the above technical solution, the connecting block 302 on the back of the sensor body 2 is extended into the connecting groove 301 to be connected to the mounting plate 1. By rotating the screw 305, the positioning rod 304 on one side of the movable plate 306 can be moved. Moving the positioning rod 304 into the positioning groove 303 can limit and fix the position of the connecting block 302, so that the connecting block 302 cannot be separated from the connecting groove 301, thereby achieving the effect of installing and fixing the sensor body 2 on the mounting plate 1. The movement of the positioning rod 304 can be controlled by simply rotating the screw 305 by hand, which is also convenient for disassembling the sensor body 2, thereby improving the convenience of sensor installation and disassembly.

[0030] Specifically, a fixing member 5 is fixedly connected to the top of the fixing plate 4 .

[0031] Through the above technical solution, the number of the fixing members 5 is conveniently two, and the two fixing members 5 are symmetrically arranged on the fixing plate 4. The fixing members 5 are provided with holes to facilitate the installation of the fixing members 5 on the inner wall of the switch cabinet.

[0032] Specifically, the mounting plate 1 forms a snap-fit ​​structure with the connecting block 302 through the connecting groove 301 , and the shape and size of the connecting groove 301 match the shape and size of the connecting block 302 , and one side of the connecting block 302 is connected to one side of the sensor body 2 .

[0033] Through the above technical solution, it is convenient to clamp the connecting block 302 on the inner wall of the connecting groove 301 opened on the mounting plate 1, so that the sensor body 2 on one side of the connecting block 302 is clamped on one side of the mounting plate 1, achieving the effect of preliminary installation of the mounting plate 1 and the sensor body 2.

[0034] Specifically, the connection block 302 forms a fixed structure with the positioning groove 303 and the positioning rod 304 , and the shape and size of the positioning groove 303 match the shape and size of the positioning rod 304 .

[0035] Through the above technical solution, it is convenient to limit and fix the connecting block 302 in the connecting groove 301 by extending the positioning rod 304 into the positioning groove 303, so that the connecting block 302 on one side of the sensor body 2 cannot be separated from the connecting groove 301, thereby achieving the effect of limiting and fixing the connecting block 302.

[0036] Specifically, the screw rod 305 forms a sliding structure with the sliding rod 307 through the moving plate 306 , and one side of the positioning rod 304 is connected to one side of the moving plate 306 .

[0037] Through the above technical solution, it is convenient to manually rotate the screw rod 305 to drive the movable plate 306 to move. During the movement of the movable plate 306, it will slide synchronously through the slide rod 307 to maintain the stability of the movement of the movable plate 306. During the movement of the movable plate 306, it will drive the positioning rod 304 to move, thereby achieving the effect of controlling the movement of the positioning rod 304, and facilitating the positioning rod 304 to be extended into the positioning groove 303 for limiting or to be detached from the positioning groove 303 to release the limit.

[0038] Specifically, the motor 601 forms a moving structure through the screw rod 602 and the moving block 603, and the threads on both sides of the screw rod 602 have opposite rotation directions, and the number of the moving blocks 603 is two.

[0039] Through the above technical solution, it is convenient for the starting motor 601 to drive the screw rod 602 to rotate and drive the moving block 603 to move at the same time, because the threads on both sides of the screw rod 602 have opposite rotation directions, and the two moving blocks 603 are symmetrically arranged on both sides of the screw rod 602, thereby making the two moving blocks 603 move relative to each other.

[0040] Specifically, the moving block 603 forms a rotating structure through the first rotating shaft 604 and the movable rod 605 , and the movable rod 605 is arranged between the first rotating shaft 604 and the second rotating shaft 606 , and the bottom of the second rotating shaft 606 is connected to the top of the mounting plate 1 .

[0041] Through the above technical solution, it is convenient for the moving block 603 to drive the movable rod 605 to rotate through the first rotating shaft 604 during the relative movement. The rotation of the movable rod 605 will push the second rotating shaft 606 at the bottom to rise and fall, and then the mounting plate 1 at the bottom of the second rotating shaft 606 will rise and fall, achieving the effect of adjusting the height of the sensor body 2.

[0042] Working principle: When using this fixed structure for switch cabinet sensors, first, when installing the sensor body 2, first insert the connecting block 302 on the back of the sensor body 2 into the connecting groove 301 on the mounting plate 1 for connection. Then, manually rotate the screws 305 on both sides. The rotation of the screws 305 drives the moving plate 306 to move. The moving plate 306 maintains stability by sliding synchronously on the sliding rod 307 during the movement. Then, the positioning rod 304 on one side of the moving plate 306 moves inward, and the positioning rod 304 extends into the positioning grooves 303 on both sides of the connecting block 302 for connection, so that the connecting block 302 is limited and fixed, and the installation is quickly completed. When it is necessary to adjust the height of the installed sensor body 2, just start the motor 601. The motor 601 drives the lead screw 602 to rotate, and the lead screw 602 drives the moving block 603 to move. During the movement of the moving block 603, the movable rod 605 on the first rotating shaft 604 will rotate. Due to the relative movement of the moving block 603, the movable rod 605 rotates in the opposite direction, and then drives the mounting plate 1 at the bottom of the second rotating shaft 606 to rise and fall, completing the adjustment of the height of the fixed sensor body 2. This completes all the work. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit. The scope is defined by the appended claims and their equivalents.
