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

Embodiment Construction

[0010] Combine below Figure 1-3 The present invention will be described in detail.

[0011] According to an embodiment, a self-sealing track-type guide structure includes a guide rail 9 and a slide base 8 that is slidably fitted with the guide rail 9 and fixedly connected with the slide member. The guide rail 9 includes a The upper side wall 91 and the bottom wall 92 thus define the housing of the guide rail sliding cavity 90 therebetween, and the sliding component base 8 has a sliding engagement seat 81 fitted in the guide rail sliding cavity 90 and a sliding engagement seat 81 with the sliding engagement seat 81. The connecting neck that is integrally connected and protrudes upwards through the longitudinal groove of the guide rail in the upper side wall 91 is used to be fixedly connected with the sliding part, and the upper side wall 91 extends toward the longitudinal groove of the guide rail There is a protective band positioning flange 911, which is used to partially ov...

Abstract

A rail type guiding structure with an automatic sealing function comprises a guide rail (9) and a sliding part base (8) which is in sliding fit with the guide rail (9) and used for being fixedly connected with a sliding part. The guide rail (9) comprises a shell which is provided with an upper side wall (91) and a bottom wall (92), so that a guide rail sliding cavity (90) is defined in the shell. The sliding part base (8) is provided with a sliding joint seat (81) and a connecting neck, wherein the sliding joint seat (81) is arranged in the guide rail sliding cavity (90) in a matched mode, and the connecting neck is integrally connected with the sliding joint seat (81), extends upwards from a guide rail longitudinal groove in the upper side wall (91) and is used for being fixedly connected with the sliding part. Protective band positioning flanges (911) extend from the upper side wall (91) towards the guide rail longitudinal groove and are used for partially overlapping an elastic protective band (7) for limiting, and the elastic protective band (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 rail-type guides, in particular to an automatically-closed rail-type guide structure. 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...
