[0017] In order to make the utility model purposes, technical solutions and advantages more clearly, the following will be further described in detail with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0018] With reference to Figures 1-2 The utility model provides a special machine tool protective cover convenient for maintaining machine tool, including shell 1 and two side doors 2, shell 1 is fixedly arranged around machine tool, and the upper portion and the lower portion are installed with upper slide rail 3 and lower slide rail 6 respectively, and the sliding of side door 2 is provided with track, and the upper end and the lower end of two side doors 2 are slidably connected with upper slide rail 3 and lower slide rail 6 respectively, so that side door 2 can stably slide along the track, the outer side of side door 2 is provided with handle 4, and the door body is opened and closed conveniently for operating personnel, and the inner side is provided with pressing strip 5 for locking side door 2.

[0019] With reference to Figure 3 Lower slide rail 6 is provided with gear rack 7 and rack hanging frame 601, gear 701 is installed on gear rack 7, and two racks 702 are slidably arranged on rack hanging frame 601, the two racks 702 are mirror image arranged with gear 701 as the center and are engaged with gear 701, and one end of rack 702 is provided with clamping groove 703 matched with the lower end of pressing strip 5.

[0020] With reference to Figure 4 Handle 4 includes support pipe 402, supporting leg 410 and semicircular arc cover pipe 401 and bottom pipe 408, both ends of support pipe 402 are connected with bottom pipe 408 and supporting leg 410 respectively, the axis of support pipe 402 and bottom pipe 408 is perpendicular, telescopic rod 405 and compression spring 411 are installed in the inside, both ends of compression spring 411 are connected with telescopic rod 405 and support pipe 402 respectively and are always in compression state to provide elastic force of telescopic rod 405 to bottom pipe 408, pressing block 403 and warping rod 407 are arranged between cover pipe 401 and bottom pipe 408, opposite bolt seats 406 are arranged on the inner wall of bottom pipe 408 and cover pipe 401, bolt 409 passes through the middle part of warping rod 407 and is connected with bolt seat 406, so that warping rod 407 is limited between two bolt seats 406, and both ends can move up and down with bolt seat 406 as fulcrum.

[0021] One end of the telescopic rod 405 is connected with the pressing strip 5, the other end is connected with one end of the lever 407, and the pressing block 403 penetrates the pipe wall of the handle pipe and is connected with the other end of the lever 407; another feasible solution is that the pressing block 403 is arranged in the bottom pipe 408, a spring 404 is arranged in the bottom pipe 408, one end of the spring 404 is in abutment with the inner wall of the cover pipe 401, and the other end of the lever 407 is away from the pressing block 403 and the cover pipe 401, the pressing block 403 is kept in abutment with the bottom pipe 408 in a natural state through the spring 404, and the restoring force of the compression spring 411 is only used to keep the pressing strip 5 in the clamping groove 703, so that the stability is improved.

[0022] When two side sliding doors 2 need to be opened simultaneously, the handle 4 on any one side sliding door 2 is pulled, the pressing strip 5 and the rack 702 are driven to rotate the gear 701, and then the rack 702 on the other side is driven to move, so that the other side sliding door 2 is driven to slide in the opposite direction, and the linkage opening is realized.

[0023] When only one side sliding door needs to be opened, the operator only needs to hold the handle 4, so that the pressing block 403 moves into the bottom pipe 408 and drives the lever 407 to rotate, the rotation of the lever 407 drives the telescopic rod 405 to extend outward, so that the pressing strip 5 is pushed out of the clamping groove 703, the unlocking is realized, and the single side sliding door 2 can slide freely along the sliding rail; in order to reduce the influence of the single side sliding door 2 on the other side sliding door 2 when the single side sliding door 2 moves, a damping wheel can be arranged on the gear frame 7, and the gear 701 is installed on the damping wheel, so that the other side sliding door 2 is prevented from being opened accidentally.

[0024] The specific embodiments of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any various other corresponding changes and deformations made according to the technical concept of the utility model should be included in the protection scope of the utility model claim.
