The penetration setting facilitates manual movement of the plug-in column 408. The top of the protective cover 2 is fixedly connected to a guide plate 406, and the guide plate 406 plays a guiding role. The inner wall of the guide plate 406 is rotatably and slidably connected to a movable plate 405, and the setting of the guide plate 406 makes the movable plate 405 movable. The plate 405 moves horizontally and also rotates to a certain extent during the movement. The outer wall of the movable plate 405 is slidably connected to the rotating plate 403. The inner wall of the right end of the rotating plate 403 is slidably connected to the movable plate 404. The rotating plate 403 can accommodate the movable plate 404 and the movable plate 405. The bottom end of the movable plate 404 is rotatably connected to the connecting cover 3. The connecting cover 3 can provide protection and waterproofing for the angle sensor body 1. The front end of the connecting cover 3 is fixedly connected to the plug-in block 402. The plug-in block 402 plays a connecting and fixing role. The top inner wall of the protective cover 2 is provided with a sealing mechanism 5. The sealing mechanism 5 prevents water vapor from entering the interior of the connecting cover 3.
[0034] Reference Figure 1-Figure 3 One end of the connecting spring 407 is fixedly connected to the outer wall of the plug-in column 408, and the other end of the connecting spring 407 is fixedly connected to the inner wall of the fixed block 401. The outer wall of the plug-in column 408 is slidably connected to the inner wall of the fixed block 401. The elasticity of the connecting spring 407 makes the plug-in column 408 have reset and limit functions. The outer wall of the fixed block 401 is provided with a square groove, and the outer wall of the plug-in block 402 is plugged into the inner wall of the square groove. The two are plugged together to merge the connecting cover 3 and the protective cover 2. The bottom end of the rotating plate 403 is rotatably connected to the top of the angle sensor body 1.

The inclined surface is set to facilitate connection and fixation.
[0035] Reference Figure 1 and Figure 4The sealing mechanism 5 includes a rotating column 504, the inner wall of which is threadedly connected with a bolt 505, which is driven to move by the rotating column 504, and the outer wall of the rotating column 504 is fixedly connected with a baffle 501, and a rubber pad is provided at the bottom of the baffle 501, which has a sealing effect, and a sealing ring 502 is provided on the inner wall of the protective cover 2, and the sealing ring 502 can be inflated so that protective covers 2 of different sizes can be used, and an inflation hole is provided on the top, and a pressure plate 503 is fixedly connected to the left end of the connecting cover 3, and the movement trajectories of the two are the same, and the outer wall of the rotating column 504 is slidably connected to the inner wall of the protective cover 2 The rotating column 504 is T-shaped, and the T-shaped setting prevents it from falling off. The bottom end of the bolt 505 is threadedly connected to the inner wall of the protective cover 2, and the threaded connection between the two fixes the baffle 501. The bottom end of the baffle 501 is plugged into the inner wall of the top end of the protective cover 2. The two are plugged together to block the inflation hole. The left end of the pressure plate 503 is plugged into the inner wall of the protective cover 2, and the outer wall of the pressure plate 503 contacts the right end of the sealing ring 502. When the left end of the pressure plate 503 is plugged into the protective cover 2, the sealing ring 502 will be squeezed, thereby causing the sealing ring 502 to deform to enhance the sealing effect.
[0036] Working principle: When the relevant personnel need to protect the angle sensor body 1, the protective cover 2 and the connecting cover 3 are moved inward, so that the plug-in block 402 is plugged into the fixed block 401. When the two are plugged in, the plug-in column 408 is reset due to the elasticity of the connecting spring 407, and then the plug-in column 408 is plugged into the plug-in block 402 to complete the fixation. When the protective cover 2 and the connecting cover 3 move toward the middle, the rotating plate 403 will rotate to a certain extent, thereby driving the movable plate 404 and the moving plate 405 to move toward the middle. At this time, the movable plate 404 rotates, and the moving plate 405 moves along the guide plate 40 6 moves, when the protective cover 2 and the connecting cover 3 are fully plugged in, the bolt 505 is rotated at this time to release the limit of the bolt 505 on the rotating column 504, and then the rotating column 504 can be moved upward to open the inflation hole, and then the sealing ring 502 can be inflated to make the deflated sealing ring 502 expand. After expansion, the baffle plate 501 and the protective cover 2 can be plugged in, and then the knob bolt 505 can be turned to complete the limit. When the angle sensor body 1 needs to be repaired, the plug-in column 408 is moved to release the limit and then the rotating plate 403 is rotated to move the protective cover 2 and the connecting cover 3 toward both ends, so that maintenance can be carried out.
