[0023] See also Figure 2 In order to stably fix the protective cover body 3, the stabilizing mechanism 1 in this embodiment includes two fixed boxes 106 fixed on the upper surface of the fixed strip 2. The fixed box 106 is in the shape of a rectangular parallelepiped with a hollow interior and a missing lower surface. The interiors of the two fixed boxes 106 are both threadedly connected with threaded rods 109. Two limiting rods 107 are fixed between the opposite sides of the left and right side walls of the inner cavity of the fixed box 106. The two adjacent limiting rods 107 are respectively located at the front and rear sides of the threaded rod 109. A rotating plate 110 is fixed on the opposite sides of the two threaded rods 109. The outer sides of the two threaded rods 109 are both threadedly connected with movable plates 108. The upper surface of the fixed strip 2 is provided with a movable groove for the movable plate 108 to be slidably connected.

[0024] A fixing hole for the card plate 101 to pass through is opened on the left side of the positioning plate 102, and the card plate 101 is slidably connected to the inside of the positioning plate 102 through the fixing hole. A limiting hole for the limiting rod 107 to pass through is opened on the left side of the movable plate 108, and the limiting rod 107 is clearance-matched with the movable plate 108 through the limiting hole. Installation grooves are opened on both sides of the inner cavity of the fixed box 106, and a first bearing is fixed inside the installation groove, and the threaded rod 109 is fixed inside the first bearing.

[0025] The stabilizing mechanism 1 also includes two movable sleeves 104 which are rotatably connected to the outer sides of the two rotating plates 110 respectively, a second bearing is fixed to the outer side of the rotating plate 110, and the second bearing is fixed to the inside of the movable sleeve 104, and two sliders 112 are slidably connected to the inside of the two movable sleeves 104, and a sliding groove for sliding connection of the sliders 112 is provided inside the movable sleeve 104, and a pressing block 103 which is slidably connected to the inside of the movable sleeve 104 is fixed between the opposite sides of the two adjacent sliders 112, and the pressing block 103 is restricted by the cooperation of the slider 112 and the sliding groove to prevent it from detaching from the movable sleeve 104, and two insertion rods 105 are fixed to the opposite sides of the two pressing blocks 103, and a through hole for the insertion rod 105 to pass through is provided on the left side of the rotating plate 110, and the insertion rod 105 is slidably connected to the inside of the rotating plate 110 through the through hole, and a return spring 111 is fixed between the opposite sides of the two insertion rods 105.

[0026] It can be seen that the stabilizing mechanism 1 fixes the protective cover body 3 on the fixed strip 2 through the cooperation of the clamping plate 101, the positioning plate 102, the fixing box 106, the limiting rod 107, the movable plate 108, the threaded rod 109 and the rotating plate 110. The clamping plate 101 and the positioning plate 102 are buried inside the fixed strip 2 to avoid damage caused by collision with other objects, thereby reducing the wear efficiency of the fixing parts, so that the protective cover body 3 can be fixed on the fixed strip 2 for a long time and stably.

[0027] See also Figure 3 In order to facilitate the cleaning of the dustproof net 404, the splitting mechanism 4 in this embodiment includes a connecting frame 401 slidably connected to the inside of the protective cover body 3, a dustproof net 404 is fixed inside the connecting frame 401, a positioning block 403 is fixed on the upper surface of the connecting frame 401, and no less than two limit springs 405 are fixed inside the protective cover body 3, and the opposite sides of the limit springs 405 on the left and right sides are fixed with limit blocks 402 inserted into the connecting frame 401.

[0028] The upper surface of the protective cover body 3 is provided with a storage groove for the sliding connection of the connecting frame 401, and a sealing gasket is fixed on the lower surface of the positioning block 403. The left and right sides of the connecting frame 401 are provided with limit grooves for the limit blocks 402 to be inserted, and the shapes of the opposite sides of the limit blocks 402 on the left and right sides are both semicircular.

[0029] Therefore, the splitting mechanism 4 facilitates the staff to take out the dustproof net 404 for cleaning at any time, or replace the damaged dustproof net 404 through the cooperation of the connecting frame 401, the limit block 402, the positioning block 403 and the limit spring 405, in case the dustproof net 404 accumulates a large amount of dust during the long-term use of the protective cover body 3 and is difficult to be removed separately for cleaning.

[0030] The working principle of the above embodiment is:

[0031] (1) When installing the protective cover body 3, insert the two positioning plates 102 on the lower side of the protective cover body 3 into the positioning grooves on the fixed strip plate 2, and then press the pressing block 103 in the direction close to the fixed box 106. The pressing block 103 drives the insertion rod 105 to move while compressing the return spring 111. When the return spring 111 is compressed to the shortest, the insertion rod 105 passes through the rotating plate 110. Then rotate the movable sleeve 104. The movable sleeve 104 drives the pressing block 103 to rotate through the slider 112. The pressing block 103 drives the rotating plate 110 to rotate through the insertion rod 105. The threaded rod 109 rotates together with the rotating plate 110 and drives the movable plate 108 to approach the protective cover body 3. When After the movable plate 108 is fitted with the inner cavity wall of the fixed box 106 close to the protective cover body 3, the clamping plate 101 penetrates the positioning plate 102 to fix it. At this time, the protective cover body 3 cannot be separated from the fixed strip 2 to complete the fixation. The stabilizing mechanism 1 fixes the protective cover body 3 on the fixed strip 2 through the cooperation of the clamping plate 101, the positioning plate 102, the fixed box 106, the limit rod 107, the movable plate 108, the threaded rod 109 and the rotating plate 110. The clamping plate 101 and the positioning plate 102 are buried inside the fixed strip 2 to avoid damage caused by impact from other objects, thereby reducing the wear efficiency of the fixing parts, so that the protective cover body 3 can be permanently and stably fixed on the fixed strip 2.

[0032] The dust screen 404 can be removed from the protective cover body 3 by the positioning block 403. The positioning block 403 can drive the connection frame 401 and the dust screen 404 to move upward together and gradually separate from the interior of the protective cover body 3. At the same time, the connection frame 401 is pushed into the interior of the protective cover body 3 along the arc of the limit block 402 during the upward movement, and the limit spring 405 is compressed by the limit block 402 until the connection frame 401 and the limit block 402 are completely separated. The limit spring 405 pushes the limit block 402 out of the interior of the protective cover body 3 through the rebound force. At this time, the dust screen 404 can be taken out for cleaning. The disassembly mechanism 4 facilitates the staff to take out the dust screen 404 for cleaning at any time or replace the damaged dust screen 404 through the cooperation of the connection frame 401, the limit block 402, the positioning block 403 and the limit spring 405. In this way, the dust screen 404 accumulates a lot of dust during the long-term use of the protective cover body 3 and is difficult to be removed alone for cleaning.
