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

A rail guide device capable of improving sealing performance comprises a guide rail piece (9) and a sliding component base (8).The sliding component base (8) is in sliding fit with the guide rail piece (9) and is used for being fixedly connected with a sliding component.The guide rail piece (9) comprises a shell which is provided with an upper sidewall (91) and a bottom wall (92) to define a guide rail sliding cavity (90) between the upper sidewall (91) and the bottom wall (92).The sliding component base (8) is provided with a sliding joint base (81) and a connecting neck part, wherein the sliding joint base (81) is arranged in the guide rail sliding cavity (90) in a matched mode, the connecting neck part and the sliding joint base (81) are integrally connected, and the connecting neck part extends out upwards through a guide rail longitudinal groove in the upper sidewall (91) and is used for being fixedly connected with the sliding component.The upper sidewall (91) extends towards the guide rail longitudinal groove to form a protective belt locating flange (911) used for partially overlapping with an elastic protective belt (7) for limiting, and the elastic protective belt (7) extends longitudinally in the guide rail longitudinal groove and is used for sealing the guide rail sliding cavity (90).

Description

technical field [0001] The invention relates to the field of track guides, in particular to a track guide capable of improving sealing performance. 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 t...
