Problems solved by technology

However, due to the influence of the slider embedded in the recessed guide rail groove, the width of the guard strip is narrower than the width of the guide rail groove, so there is still a gap and it is difficult to prevent the entry of pollutants at all

Abstract

The invention relates to a track guiding device capable of avoiding pollutant accumulation. The device comprises a guide rail piece and a sliding part pedestal which is slidably matched with the guide rail piece and is fixedly connected to a slide part, wherein the guide rail piece comprises a housing provided with an upper side wall and a bottom wall so as to define a guide rail sliding cavity therebetween; the sliding part pedestal is provided with a sliding joining seat which is matched in the guide rail sliding cavity and a connecting neck which is integrally connected to the sliding joining seat and extends upward through a longitudinal groove of a guide rail in the upper side wall for being fixedly connected to the sliding part; a roller is mounted in the bottom of the sliding joining seat and the roller is propped against the bottom wall, and a positioning flange of a protective belt extends in the direction, facing the longitudinal groove of the guide rail, of the upper side wall for being partially overlapped with the elastic protective belt which longitudinally extends into the longitudinal groove of the guide rail and closes the guide rail sliding cavity for limitation.

Description

technical field [0001] The invention relates to the field of rail guides, in particular to a rail guide that can avoid accumulation of pollutants. Background technique [0002] In the prior art, rail-type guiding is a commonly used guiding method, which is used to guide the movement of sliding components. The specific structure of the guide rail has a protruding type and a concave type. For the upward protruding guide rail, due to its structural shape, it is difficult to adapt to some occasions that require no protrusion. Inner concave guide rails are widely used in some occasions that require the compactness of the equipment and the flatness of the shape. However, due to its concave structure, this kind of concave guide rail is susceptible to the entry of external pollutants to cause the accumulation of pollutants, which especially has an impact on the precision of the guide device for precision motion. Moreover, it is inconvenient to maintain, which adversely affects th...
