Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of linear guide rails, in particular to a linear guide rail with a waterproof and anti-chip structure. Background Art
[0002] The dual-axis guide rail is a high-speed guide rail developed in Germany. The slider and roller are integrally formed. The dual-axis guide rail is divided into internal clamping type and external clamping type. The external clamping type has the slider on the outside of the guide rail, while the internal clamping type has the slider on the inside of the guide rail.
[0003] When using the current linear guide rails, since the slider is directly installed inside the groove of the guide rail, the opening of the groove is exposed to the outside when it is open. External waste will enter the interior through the gap between the opening of the groove and the slider, resulting in blockage of the interior of the groove, making the movement of the slider not smooth and affecting subsequent use. When a single sealing strip is used at the opening of the groove, there will still be a gap in the sealing strip due to the sliding movement. Utility Model Content

The use of an adjustable extrusion sealing structure allows it to meet the installation and sealing needs of multiple specifications during use.
