The positioning fixing part is of an L-shaped structure, so that the positioning fixing part is suitable for a side insertion installation mode.
The width of the lower part of the sealing strip is gradually increased from top to bottom, and the two dustproof scraping blades are distributed in a splayed shape. The lower part of the sealing strip is more stable, and the two dustproof scraping sheets are distributed in a splayed shape, so that the dustproof effect is better.
The lower part of the sealing strip is attached to the region opposite to the lower part of the outer side end of the return device, so that the sealing strip is more stably fixed.
Compared with the prior art, the utility model has the advantages of:
1) After the location fixed part of sealing strip was installed in the vice location mounting groove that returns to on the ware of rolling guide, in adverse circumstances, the structure of double-deck dustproof doctor-bar not only can effectively prevent external dust, the bits end gets into the vice inside of rolling guide through the clearance between the linear guide in the rolling guide is vice and the slider, dustproof respond well, the vice inside abnormal wear of rolling guide has effectively been avoided, and in rolling guide is vice in service, dustproof doctor-bar can be with the dust of outside in the place ahead of slider, the bits end strikes off, thereby rolling guide's vice running accuracy and life have been guaranteed.
2) The positioning fixing part is used as a stressed part of the sealing strip when the return device in the rolling guide rail pair runs on the linear guide rail along with the sliding block, and the sealing strip can also keep stable in the state that the sliding block runs at high speed due to large stressed contact area.
3) Because the lower part of the sealing strip is positioned outside the lower part of the outer side end of the returning device, namely the lower part of the sealing strip is positioned in a relatively larger space, the area of the dustproof scraping blade can be properly increased, and the dustproof effect can be enhanced to a certain extent; in addition, the sealing strip is more convenient to replace.
