DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model, and apparently, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0022] Refer to Figures 1-7The utility model provides a slider type static pressure guide rail combination sealing device, including static pressure slide rail body 1 and slider body 2, and the slider body 2 is movably arranged on static pressure slide rail body 1, and the both sides of slider body 2 are all installed with detachable sealing element 3.

[0023] Wherein, the inside of mounting piece 4 is all set up movable cavity 41, and movable piece 5 is movably arranged in movable cavity 41. A plurality of guide posts 411 are fixedly arranged in movable cavity 41, and movable piece 5 moves by guide post 411. By the setting of guide post 411, the stability of movable piece 5 in the moving process can be improved.

[0024] Wherein, the inner wall of movable cavity 41 is all installed spring 412 towards movable piece 5 outside guide post 411, and the other end of spring 412 is all connected with movable piece 5. By the setting of spring 412, movable piece 5 can be pushed outward, so that limiting piece 52 can be stably clamped in limiting cavity 22.

[0025] Wherein, limiting piece 52 is all fixedly installed on movable piece 5, and corresponding limiting piece 52 is all adaptedly set up through cavity 42 on mounting piece 4.

[0026] Wherein, the one end of mounting piece 4 corresponding movable piece 5 is all outwardly set up push plate cavity 43, and the one end of movable piece 5 is from push plate cavity 43 and is fixedly connected with push plate 51. The size of push plate 51 is greater than push plate cavity 43, which makes push plate 51 can be blocked on the outside of push plate cavity 43 under normal circumstances, to prevent dust from entering into movable cavity 41 through push plate cavity 43.

[0027] In the embodiment, the slider body 2 is adapted to slide on the static pressure slide rail body 1, and the sealing element 3 is installed on both sides of the slider body 2. It is worth noting that the specific working structure and working mode between the static pressure slide rail body 1 and the slider body 2 are prior art, and they do not belong to the technical problem of quick disassembly of the sealing element 3 to be solved in the present technical solution, so they are not described in detail in the present technical solution.

[0028] Further, the sealing element 3 in the embodiment is provided with four mounting pieces 4, two upper and two lower, and the movable pieces 5 in the mounting pieces 4 are all moved outward and clamped. When the user needs to install the sealing element 3 on the slider body 2, only two hands are needed to push the two push plates 51 on the upper and lower sides inward at the same time to drive the movable pieces 5 to move inward, thereby driving the limiting pieces 52 to retract into the movable cavities 41, and the springs 412 are compressed at this time.

[0029] Then the user only needs to insert the mounting piece 4 into the mounting cavity 21, at this time the through cavity 42 on the mounting piece 4 is matched and aligned with the limiting cavity 22. Then the user only needs to loosen the push plate 51, at this time the movable piece 5 can be automatically reset by the elastic force of the spring 412, thereby driving the limiting piece 52 to reset and move into the limiting cavity 22, so as to realize the fixed installation of the sealing piece 3.

[0030] Further, when the user needs to disassemble and replace the sealing piece 3, only need to move the limiting piece 52 into the movable cavity 41 through the push plate 51 to release the clamping between the limiting piece 52 and the limiting cavity 22. Then only need to pull out the sealing piece 3, which can realize the disassembly of the sealing piece 3.

[0031] Further, the mounting piece 4 in the technical solution can be arranged at any position on the sealing piece 3, only need to ensure that the left and right mounting pieces 4 are parallel, the corresponding mounting cavity 21 and limiting cavity 22 are arranged on the sliding block body 2, and the user can conveniently push and adjust all the push plates 51.

[0032] In the utility model, the sealing piece 3 can be fixed and assembled on the sliding block body 2 through the matching and clamping between the mounting piece 4 and the mounting cavity 21, and the locking between the limiting piece 52 and the limiting cavity 22. This assembly method of the sealing piece 3 is simple and convenient, and is convenient for the user to disassemble and replace the aging sealing piece 3 in the later period.

[0033] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
