Embodiment Construction
[0010] Combine below Figure 1-3 The present invention will be described in detail.
[0011] According to an embodiment, a track guiding device that can reduce the entry of pollutants 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. The guide rail 9 includes There is an upper side wall 91 and a bottom wall 92 so as to define a housing of a 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 a sliding engagement seat 81 with the sliding engagement seat 81 is integrally connected and protrudes upward through the longitudinal groove of the guide rail in the upper side wall 91. The connecting neck is used to be fixedly connected with the sliding part. A ball groove 95, and a ball 96 is installed in the ball groove 95, and the ball 96 abuts against the lower end surface of the sliding joint seat 81, and the b...

The invention discloses a rail guide device capable of reducing contaminant entrance. The rail guide device comprises a guide rail part and a sliding component base in sliding fit with the guide rail part for being fixedly connected to a sliding component; the guide rail part comprises a shell with an upper side wall, a bottom wall and a guide rail sliding cavity defined between the upper side wall and the bottom wall; the sliding component base is provided with a sliding joint base and a connecting neck part, wherein the sliding joint base is arranged inside the guide rail sliding cavity in a matched mode, and the connecting neck part is integrally connected to the sliding joint base and extends out upwards through a guide rail longitudinal groove in the upper side wall for being fixedly connected to the sliding component; ball grooves are formed in the bottom wall in the extension direction of the guide rail part, and balls are installed in the ball grooves and abut against the lower end face of the sliding joint base; a protective belt locating flange extends in the direction towards the guide rail longitudinal groove of the upper side wall and is used for partially overlapping with an elastic protective belt longitudinally extending inside the guide rail longitudinal groove and sealing the guide rail sliding cavity for realizing the limiting effect.
Description
technical field [0001] The invention relates to the field of rail guides, in particular to a rail guide that can reduce the entry of pollutants. 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 ...
