Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Next, the present invention will be described in detail with reference to the drawings, wherein for convenience of illustration, the cross-sectional view of the device structure is not enlarged partially according to the general scale, and the drawings are only examples, which should not limit the scope of the present invention. In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a wear-resistant drawer slide rail which can effectively strengthen the elastic interaction force between slide rail components, reduce the hard friction coefficient between the slide rail components and greatly prolong the service life of the drawer slide rail.

Referring to fig. 1-3, the wear-resistant drawer slide according to the present embodiment includes a main body including a drawer 100, a slide 200, a load-bearing housing 300, and a U-shaped rail 400.

The drawer 100, the sliding rail 200, it is set up in the bottom edge both sides of the drawer 100, there are arcuate rails 210 at the inboard bottom of the sliding rail 200, the first buffer cushion 220 of the joint of arcuate rail 210 and sliding rail 200, the arcuate rail 210 forms the elastic structure through first buffer cushion 220 and sliding rail 200, arcuate rail 210 and first buffer cushion 220 and bottom of the sliding rail 200 are flush, the bottom inboard of arcuate rail 210 and top outside of the running roller 420 are the upper and lower gomphosis-like to distribute, the sliding rail 200 locates at the straight top of the U-shaped rail frame 400 at the same time, the first buffer cushion 220 can form certain elastic support between arcuate rail 210 and sliding rail 200, because the running roller 420 will form the abrasion to the inboard wall of sliding rail 200 in the long-term operation, therefore arcuate rail 210 not only can form the protection to the inboard wall of sliding rail 200, can reduce the abrasion that the running roller 420 causes to the arcuate rail 210 effectively under the elastic support of the first buffer cushion 220 at the same time, thereby playing the role of double protection.

The bearing housing 300 is disposed at the outer surrounding position of the drawer 100, the bearing housing 300 is disposed at the U-shaped groove 310 corresponding to the upper and lower parts of the sliding rail 200, the U-shaped rail frame 400 is disposed at the inner side of the U-shaped groove 310, the second buffer 410 is disposed at the joint of the bottom of the U-shaped rail frame 400 and the U-shaped groove 310, the roller 420 is disposed at the inner side of the upper part of the U-shaped rail frame 400, the limit shaft 430 is disposed at the joint of the U-shaped rail frame and the roller 420, the U-shaped rail frame 400 forms an up-and-down elastic structure with the U-shaped groove 310 through the second buffer 410, the U-shaped rail frame 400 and the limit shaft 430 are fixed into a whole, although the roller 420 can form a joint sliding to the arc-shaped rail frame 210 through a self-induced rotation and reduce a friction coefficient therebetween, the roller 420 also plays a role of vertical bearing, and wears the arc-shaped rail frame 210 when used for a long time, so that the second buffer 410 can form an elastic support between the U-shaped rail frame 400 supporting the roller 420 and the U-shaped groove 310, thereby make running roller 420 can also form perpendicular elasticity when laminating the contact, and effectively reduced the mutual wearing and tearing between arc rail 210 and the running roller 420, running roller 420 forms swivelling joint through between spacing axle 430 and the U type rail frame 400, do not contact each other between the outer wall bottom of running roller 420 and the inner wall bottom of U type rail frame 400, running roller 420 evenly arranges along the inboard equidistance of U type rail frame 400, arc rail 210 passes through to constitute horizontal sliding structure between running roller 420 and the U type rail frame 400, running roller 420 can form the sliding support laminating to slide rail 200 and arc rail 210 under spacing axle 430's articulated effect, and make slide rail 200 more smooth when the pull, also effectively reduced the coefficient of friction between the two.

In summary, in the wear-resistant drawer slide of the present embodiment, firstly, when the drawer 100 is pulled and pulled, the slide 200 and the arc-shaped rail 210 are driven to move simultaneously, and at this time, the upper portion of the roller 420 forms a close sliding with the arc-shaped rail 210, and herein, the first buffer pad 220 forms a certain elastic support between the arc-shaped rail 210 and the slide 200, and the arc-shaped rail 210 can not only protect the inner wall of the slide 200, but also effectively reduce the wear of the roller 420 on the arc-shaped rail 210 under the elastic support of the first buffer pad 220, although the roller 420 forms a close sliding with the arc-shaped rail 210 through the self-passive rotation, the roller 420 also plays a vertical bearing role, and wears the arc-shaped rail 210 during long-term use, so that the second buffer pad 410 forms an elastic support between the U-shaped rail frame 400 for supporting the roller 420 and the U-shaped groove 310, thereby, the roller 420 can form vertical elasticity while being attached and contacted, and mutual abrasion between the arc rail 210 and the roller 420 is effectively reduced.
