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] A rail guiding device with a stable structure according to an embodiment, comprising 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, and 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 th...

Abstract

A rail guide device stable in structure comprises a guide rail piece (9) and a sliding part base (8) which is in sliding fit with the guide rail piece (9) and used for being fixedly connected with a sliding part. The guide rail piece (9) comprises a shell, wherein the shell comprises an upper side wall (91) and a bottom wall (92) so that a guide rail sliding cavity (90) can be defined between the upper side wall (91) and the bottom wall (92). The sliding part base (8) comprises a sliding connection base (81) matched in the guide rail sliding cavity (90), and a connection neck part which is integrally connected with the sliding connection base (81), extends upwards through a guide rail longitudinal groove in the upper side wall (91) and is used for being fixedly connected with the sliding part. A protection belt positioning flange (911) extends on the upper side wall (91) in the direction towards the guide rail longitudinal groove and is used for being partly overlapped with an elastic protection belt (7) longitudinally extending in the guide rail longitudinal groove and used for closing the guide rail sliding cavity (90) so that limiting can be conducted.

Description

technical field [0001] The invention relates to the field of rail guides, in particular to a rail guide device with a stable 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 the use and s...
