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 closed rail guiding device, comprising a rail member (9) and a sliding member base (8) that is slidably matched with the rail member (9) and fixedly connected with the sliding member, the rail member (9) includes A housing having an upper side wall (91) and a bottom wall (92) thereby defining a guide rail slide chamber (90) therebetween, the slide member base (8) having a sliding member fitted in the guide rail slide chamber (90) The joint seat (81) and the joint neck integrally connected with the sliding joint seat (81) and protruding upward through the longitudinal groove of the guide rail in the upper side wall (91) are used to be fixedly connected with the sliding part, The upper side wall (91) is extended with a protective belt positioning flange (911) in the direction towards the longitudinal groove of the guide rail, used to extend longitudinally in the longitudinal groove of the guide rail and used for aligning the sliding cavity of the guide rail ( 90) The elastic protective belts (7) for closing are partially overlapped to limit the position.

Description

technical field [0001] The invention relates to the field of rail guides, in particular to a closed 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 equip...
