The inner wall of the groove 3532 transmits lubricating oil to the corresponding contact pieces 354, so that each contact piece 354 can obtain lubricating oil with a short transmission path without interruption, thereby providing the rail 100 and the The sliding block 200 has better lubricating effect.

[Technical effect of the embodiment of the present utility model]

To sum up, the beneficial effect of the present invention is that the linear slide rail provided by the present invention can be fixed to the lower metal sheet corresponding to the side wing portion through the dust-proof module, and can be fixed to the lower metal sheet corresponding to the side wing portion without any gap. The lower dust-proof strip formed on the lower metal sheet can effectively prevent dust from entering the gap between the track and the slider, and effectively achieve a certain degree of improvement in the dust-proof effect, so as to maintain the slider on the track. smoothness of sliding. Furthermore, the lower metal sheet can also prevent the balls from rolling out of the lower rolling groove, and at the same time, it can also prevent the balls from directly contacting the lower dust-proof strip, causing particles to affect the sliding smoothness of the track. .

The contents disclosed above are only the preferred feasible embodiments of the present invention, and are not intended to limit the scope of the present invention. Therefore, any equivalent technical changes made by using the contents of the description and drawings of the present invention are included in the present invention. within the scope of the new patent.
