Linear guides are mainly used in mechanical structures with relatively high precision requirements. There is no intermediate medium between the moving element and the fixed element of the linear guide, but rolling steel balls.

[0003] Linear guides are usually lubricated to improve smoothness during movement. However, the guide grooves are usually open, and long-term operation may cause more impurities to enter the guide grooves, affecting the smoothness of movement. Utility Model Content

[0007] The support pile is arranged above the guide rail base, a guide groove is provided on the surface of the guide rail base, and a moving block sliding in the guide groove is fixed at the bottom of the support pile;

[0008] The functional column is fixed on the side wall of the guide rail base, and a storage bin is fixed on the top of the functional column;

[0009] The cover plate is inserted into the cavity of the storage bin, and a push block is fixedly arranged at the bottom of the cover plate;

[0010] The transition groove is opened on both sides of the supporting piles;

[0011] The top block is fixed on the surface of the supporting pile, and the top block and the push block are located at the same horizontal height.

[0012] Furthermore, a support block is arranged between the two groups of guide grooves, and a sliding block slidably matched with the support block is arranged at the bottom of the support pile.

[0013] Furthermore, guide holes are arranged at intervals at the bottom of the guide groove, and gathering holes are transversely arranged inside the guide rail base, and the guide holes are connected with the gathering holes.

[0014] Furthermore, a plug hole is provided on the side wall of the support pile, a positioning rod inserted into the plug hole is fixedly provided at the bottom of the guide rail support plate, and a threaded portion is provided at the front end of the positioning rod.

[0015] Furthermore, a spring is arranged in the cavity of the storage bin, and two ends of the spring are respectively fixed to the cover plate and the inner wall of the cavity of the storage bin.

[0016] Furthermore, the groove height of the transition groove matches the overlapping height of the cover plate and the push block.

[0017] Furthermore, the top blocks are symmetrically distributed on both sides of the supporting piles, and both the top blocks and the push blocks adopt a triangular structure.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The present application symmetrically arranges cover plates that can be moved toward the middle above the guide rail base, and arranges springs in the grooves of the storage bin to drive the cover plates forward, so that the two sets of cover plates are closed at the opening above the guide rail base.
