The protective component 6 can reduce the entry of dust and foreign matter. There is a gap between the accordion protective cover 4 and the slide rail 3, thereby improving the protection effect of the guide rail.

[0025] The protective component 6 includes a plurality of limiting holes 61, and the plurality of limiting holes 61 are opened on the surfaces of both sides of the support plate 1. A limiting block 11 is arranged inside the limiting hole 61. Two folding plates 62 are arranged on both sides of the support plate 1, and are limited by the limiting block 11 on the same side. A connecting block 63 for reinforcement is fixedly arranged in the middle of the folding plate 62, and the connecting block 63 can reinforce the middle of the folding plate 62. A limiting plate 64 is fixedly arranged at the top end of the folding plate 62, and the limiting plate 64 provides guidance for the movement of the accordion protective cover 4, so as to prevent the accordion protective cover 4 from leaving the surface of the slide rail 3. A reset component 7 is arranged outside the limiting block 11, and the folding plate 62 can be easily installed or disassembled through the reset component 7.

[0026] The reset assembly 7 includes a connecting tube 71, a sleeve 72, a guide rod 73 and a reset spring 74. The connecting tube 71 is arranged on the surface of the folding plate 62 and is located above the limiting hole 61. The top end of the inner wall of the connecting tube 71 is fixedly provided with a sleeve 72. The middle part of the sleeve 72 is slidably fitted with a guide rod 73. The surface of the guide rod 73 is sleeved with a reset spring 74. The reset spring 74 is in a contracted state in a natural state. The bottom end of the guide rod 73 is fixedly connected to the surface of the limiting block 11. The reset spring 74 can pull the limiting block 11 to move upward.

[0027] The bottom end of the support plate 1 is provided with a plurality of circular grooves 111 corresponding to the limiting blocks 11 . The limiting blocks 11 can rotate on the inner walls of the circular grooves 111 . The circular grooves 111 and the limiting holes 61 are connected vertically.

[0028] The inner wall of the accordion protective cover 4 is slidably matched with the surface of the slide rail 3 to guide the movement of the accordion protective cover 4 .

[0029] One end of the return spring 74 is fixedly connected to the bottom end of the sleeve 72 , and the other end of the return spring 74 is fixedly connected to the top end of the limit block 11 . The return spring 74 provides an upward pulling force for the limit block 11 .

[0030] A mounting post 8 is disposed at the top of the connecting seat 5 , and a width of the mounting post 8 is smaller than a distance between two limiting plates 64 .

[0031] A mounting seat 81 is fixedly provided in the middle of the top of the mounting column 8, and mounting holes 82 are provided at the four corners of the surface of the mounting seat 81, which are connected to external equipment through the cooperation of bolts.

[0032] When in use, firstly, in order to effectively protect the surface of the slide rail 3, retractable accordion protective covers 4 are provided on both sides of the surface of the slide rail 3. The connecting seat 5 can drive the accordion protective covers 4 on both sides to be retracted during the movement of the slide rail 3, so as to protect the surface of the slide rail 3 without hindering the movement of the connecting seat 5. Since the accordion protective cover 4 is easily damaged during long-term use, in order to facilitate the maintenance and replacement of the accordion protective cover 4, the retractable accordion protective cover 4 is respectively bonded and connected with the first accordion fur surface 51 and the second accordion fur surface 21 through the Velcro hook surfaces 42 at both ends. The accordion protective cover 4 can be conveniently disassembled through the Velcro hook surfaces 42, so that the staff can conveniently perform maintenance and replacement of the accordion protective cover 4.

[0033] Since there is a gap between the accordion protective cover 4 and the slide rail 3, in order to reduce the entry of dust and foreign matter, folding plates 62 for easy installation and disassembly are provided on both sides of the support plate 1. The two folding plates 62 can improve the protection effect of the side of the slide rail 3. The connecting block 63 can reinforce the middle part of the folding plate 62. When the folding plate 62 is installed, the limit block 11 is pressed downward by the guide rod 73. When the limit block 11 passes through the limit hole 61, the limit block 11 is rotated to 90 degrees clockwise by the guide rod 73, and the reset spring 74 pushes the limit block 11 to move forward. The pulling force on the limit block 11 makes the limit block 11 come into contact with the top of the inner wall of the circular groove 111, thereby completing the fixation of the folding plate 62. When disassembling, the limit block 11 is pressed by the guide rod 73, and the limit block 11 is rotated 90 degrees counterclockwise by the guide rod 73. The limit block 11 moves upward under the action of the pulling force of the reset spring 74, so that the limit block 11 is disengaged from the limit hole 61, thereby completing the disassembly of the folding plate 62. The limit plate 64 provides guidance for the movement of the accordion protective cover 4, which can prevent the accordion protective cover 4 from separating from the surface of the slide rail 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
