Rail type guide structure capable of running smoothly

Abstract

A rail type guide structure capable of running smoothly comprises a guide rail piece and a sliding component base which is in sliding fit with the guide rail piece and is used for being fixedly connected with a sliding component. The guide rail piece comprises a shell, and the shell is provided with an upper wall and a bottom wall, so that a guide rail sliding cavity is defined in the shell. The sliding component base is provided with a sliding joint seat matched in the guide rail sliding cavity and a connecting neck part and is used for being fixedly connected with the sliding component, and the connecting neck part is integrally connected with the sliding joint seat and stretches upwards through a guide rail longitudinal groove in the upper wall. Ball grooves in the extending direction of the guide rail piece are formed in the bottom wall. Balls are mounted in the ball grooves and abut against the lower end face of the sliding joint seat. Protection belt locating flanges are arranged on the upper wall in the direction of the guide rail longitudinal groove in an extending manner and used for being partially overlapped with an elastic protection belt so that limiting can be achieved, wherein the elastic protection belt longitudinally extends in the guide rail longitudinal groove and is used for sealing the guide rail sliding cavity.

Description

Technical field [0001] The invention relates to the field of track-type guides, in particular to a track-type guide structure that can run smoothly. Background technique [0002] In the prior art, rail-based guidance is a commonly used guidance method for guiding the movement of sliding components. The specific structure of the guide rail has a protruding type and a concave type. For the up-protruding guide rail, due to its structural shape, it is difficult to adapt to some occasions that require no protrusions. Recessed guide rails are widely used in some occasions that require the compactness and flatness of the equipment. However, due to its recessed structure, this kind of concave guide rail is susceptible to the ingress of external pollutants and the accumulation of pollutants, which particularly affects the precision of the precision movement guide device. Moreover, its maintenance is inconvenient, which will adversely affect the use and the life of the equipment. [0003...

AI Technical Summary

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
