In addition, in the embodiment of the present utility model, the limiter of the retainer is designed with a dislocation-arranged limit hole, and the abutting member can be fitted into the limiter and the slider, so that the two circulating sleeves arranged in a cross-displacement are held The device is effectively positioned. The retainer can also prevent impurities or dust from entering the rolling groove through the abutting surface of the guide rail through the dust-proof strip.

In addition, the embodiment of the present invention forms an oil guide path through the dust-proof parts, so that the cover does not need to form an oil passage as known, and thus makes the mold design of the cover of the present invention simpler and easier to open. The dust-proof parts in the end cover module are sandwiched between the cover body and the slider. This structural design makes the linear slide rail have a shock-absorbing effect, and can absorb the cover body and the slider through the soft dust-proof parts. The effect of the collocation error of the two blocks.

The above description is only the preferred feasible embodiment of the utility model, and it is not used to limit the patent scope of the utility model. All equal changes and modifications made according to the claims of the utility model shall be covered by the utility model. scope.
