The outer wall of the rotating shaft 402 is rotatably connected to a driving gear 403, and the driving gear 403 is provided with multiple groups and distributed in an array from top to bottom, and the number of teeth gradually increases. The top inner wall of the shell 1 is rotatably connected to a transmission shaft 406, and the outer wall of the driving gear 403 is rotatably connected to a transmission gear 405. The transmission gear 405 is provided with multiple groups and distributed in an array from top to bottom, and the number of teeth gradually decreases. The inner wall of the bottom end of the transmission shaft 406 is threadedly connected to a threaded rod 404, and the rotation of the threaded rod 404 plays an adjusting role. The top of the rod 404 is rotatably connected to the connecting column 410, and the top of the connecting column 410 is fixedly connected to the moving block 407. The rotation of the threaded rod 404 drives the connecting column 410 and its moving block 407 to move synchronously. The inner wall of the moving block 407 is elastically connected to the plug-in block 408 through the connecting spring 409. There are two groups of plug-in blocks 408, which are respectively located at the left and right ends of the moving block 407. At the same time, an inclined surface is provided at the end of the plug-in block 408. The inclined surface is provided to facilitate the movement of the plug-in block 408. The top of the transmission shaft 406 is fixedly connected to the radar body 3, and the movement trajectories of the two are consistent. A dustproof mechanism 5 is provided at the top of the shell 1, and the radar body 3 is dustproofed by the dustproof mechanism 5.

[0035] Reference Figure 4-Figure 5The bottom end of the motor 401 is fixedly connected to the inner wall of the housing 1, and the housing 1 supports the motor 401. The top end of the rotating shaft 402 is rotatably connected to the inner wall of the top end of the housing 1. The two rotate to avoid motion interference. The outer tooth end of the driving gear 403 is engaged with the outer tooth end of the transmission gear 405. The engagement of the two drives the transmission gear 405 to rotate through the driving gear 403. The inner wall of the transmission gear 405 is rotatably connected to the outer wall of the transmission shaft 406. Through the rotation of the driving gear 403 on the rotating shaft 402, a group of fixed transmission gears 405 on the transmission shaft 406 are driven to rotate. One end of the connecting spring 409 is fixedly connected to the plug-in block 408 The outer wall of the plug-in block 408 is connected to the inner wall of the moving block 407, and the other end of the connecting spring 409 is fixedly connected to the inner wall of the moving block 407.

The outer wall of the plug-in block 408 is plugged into the inner wall of the transmission gear 405. When the two are plugged in, a set of transmission gears 405 and the transmission shaft 406 are fixed and can rotate. A sliding groove is provided on the inner wall of the transmission shaft 406, and the outer wall of the moving block 407 is slidably connected to the inner wall of the sliding groove. The sliding groove is set through and guides the moving block 407, so that the moving block 407 can only move in the vertical direction.

[0036] Reference Figure 1-Figure 3 The dustproof mechanism 5 includes a fixed block 502, the inner wall of the fixed block 502 is elastically connected to the plug post 504 by a return spring 503, and the left end of the plug post 504 is provided with an inclined surface, which is convenient for installation. The top of the shell 1 is rotatably connected to the dust seat 501, and the rotation of the dust seat 501 is closed to prevent dust from entering the interior of the radar body 3. One end of the return spring 503 is fixedly connected to the inner wall of the fixed block 502, and the other end of the return spring 503 is fixedly connected to the outer wall of the plug post 504. The outer wall of the plug post 504 is slidably connected to the inner wall of the fixed block 502. The elasticity of the return spring 503 makes the plug post 504 have a reset and limit function. The bottom end of the fixed block 502 is fixedly connected to the top of the shell 1, and the fixed block 502 is supported by the shell 1. The left end of the plug post 504 is plugged into the right end of the dust seat 501, and the two are plugged together to prevent the dust seat 501 from rotating.

[0037] Working principle: When the radar body 3 needs to be adjusted, first open the door 2, then hold the transmission shaft 406 with one hand, and turn the threaded rod 404 at the bottom with the other hand, so that the threaded rod 404 moves upward, thereby driving the moving block 407 to move upward. When the moving block 407 moves upward, it will drive the plug-in block 408 to move upward, and then the plug-in block 408 moves to the inner wall of the corresponding transmission gear 405, and then start the motor 401 so that the output end of the motor 401 drives the rotating shaft 402 to rotate, so that the driving gear 403 drives the transmission gear 405 to rotate, thereby achieving the adjustment purpose.

[0038] When the radar body 3 is no longer in use, the dust seat 501 is flipped over so that the dust seat 501 rotates clockwise, thereby contacting the inclined surface of the plug-in column 504, causing the plug-in column 504 to move to the right end. When the dust seat 501 is flipped ninety degrees, the plug-in column 504 is reset due to the elasticity of the reset spring 503, and then the plug-in column 504 is plugged and fixed to the dust seat 501, which is simple and convenient to operate.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
