Anti-loosening buffer guide rail structure

Technical Field

The utility model relates to the technical field of guide rails, in particular to a locking buffering guide rail structure.

Background

Buffer guide rails are usually installed on furniture such as desks and wardrobes to enable furniture components such as drawers on desks and cabinet doors on wardrobes to slide. A buffer rail is a groove or ridge made of metal or other material that can bear against, secure, guide, and reduce friction with a moving device or equipment. Longitudinal grooves or ridges on the surface of the buffer rail for guiding and securing the drawer. A cushioning slide rail refers to a practical manifestation of a slide rail, generally referred to as a slide rail having a cushioning effect.

However, in the existing buffer guide rail, a guide rail buffer is generally arranged at the tail end of an outer rail to realize buffer pushing of the guide rail, but in the final pushing process, the inner rail naturally collides with the middle rail under the action of inertia, so that the impact buffer of the middle rail is easily damaged, and the buffer guide rail is easily fixed to be loose; therefore, the existing requirements are not met, and a locking buffer guide rail structure is provided for the locking buffer guide rail structure.
