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 retractable rail guide device includes a rail member 9 and a sliding member base 8 that is slidably fitted with the rail member 9 and fixedly connected with the sliding member. The rail member 9 includes an upper side The wall 91 and the bottom wall 92 thus define the housing of the guide rail sliding cavity 90 therebetween, the sliding member base 8 has a sliding engagement seat 81 fitted in the guide rail sliding cavity 90 and is integrally connected with the sliding engagement seat 81 And the connecting neck protruding 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. A positioning flange 911 is used to partially overlap the elastic protection band 7 that extends longitudinally in the longitudinal groove of the guide rail and is used to close the sliding cavity 90 ...

Abstract

The invention discloses a retractable rail guide device. The retractable rail guide device comprises a guide rail part (9) and a sliding component base (8), wherein the sliding component base (8) is matched with the guide rail part (9) in a sliding mode and is used for being fixedly connected to a sliding component; the guide rail part (9) comprises a shell with an upper side wall (91), a bottom wall (92) and a guide rail sliding cavity (90) defined between the upper side wall (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 inside the guide rail sliding cavity (90) in a matched mode, and the connecting neck part is integrally connected to the sliding joint base (81), extends upwards through a guide rail longitudinal groove in the upper side wall (91) and is used for being fixedly connected to the sliding component; a protective belt locating flange (911) extends on the upper side wall (91) and towards the guide rail longitudinal groove and is used for partially overlapping with an elastic protective belt (7) extending inside the guide rail longitudinal groove in the longitudinal direction and closing the guide rail sliding cavity (90) for realizing the limiting effect.

Description

technical field [0001] The invention relates to the field of rail guides, in particular to a retractable rail guide. 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 the use and service life of the ...
