Detailed Description

Example 1: referring to fig. 1-3, a drawer slide rail comprises a support 1, a middle rail 2 and an inner rail 3 which are respectively connected in a matched mode, wherein the middle rail 2 and the inner rail 3 are respectively arranged on the inner side of the support 1, the support 1 is provided with a support web 11 which is longitudinally arranged, the longitudinal support web 11 is provided with support side walls 12 which are arranged along the longitudinal edges of two sides of the support web, and the back surface of the support web 11 is provided with at least one transverse first concave part 13 or at least one second concave part 14 which is arranged at the turning position of the support web 11 and the side walls.

In the specific use process, the locking mechanism can be configured according to the needs.

The arrangement of the first concave part 13 can change the stress condition of the bearing web 11, change the straight line stress in the tail end of the general structure, reduce the deformation of the bearing web 11 in the stress process, reduce the subsequent deformation of the middle rail 2, and further improve the bearing capacity of the bearing web 11.

The second concave part 14 can change the stress condition of the support side wall plane of the support web 11 and the turning position of the support side wall 12 and the support web 11, prevent the support side wall 12 plane of the support web 11 from deforming after multiple uses, and prevent the turning position of the support side wall 12 and the support web 11 from breaking or being fatigued by metal to influence the whole service life of the product.

Compared with the processing mode of thickening the thickness of the support web 11 in the traditional process, the bearing of the support web 11 can be improved by simply punching the slide rail in the punching process without adding any other working procedures and cost, and compared with the mode of thickening the support web 11, the processing mode of thickening the support web 11 has low cost and can achieve the same technical effect.

In a preferred embodiment, the back of the support 1 may be provided with a first concave portion 13 and a second concave portion 14 at positions close to the extraction end, the first concave portion 13 extends from the support web 11 to the support side wall of the first concave portion to be connected with the second concave portion 14, so that the stress condition of the support side wall 12 can be further improved, deformation of the two support side walls 12 can be prevented in practical application, the overall bearing capacity of the sliding rail is improved, particularly in the implementation process, the first concave portions 13 are multiple groups arranged at intervals, and in a preferred structure, the second concave portions 14 symmetrically arranged are respectively arranged at turning positions of the two support side walls 12 and the support web 11.

Preferably, the central portion of the seat web 11 of the first recess 13 extends symmetrically towards both sides thereof, which may be arranged at a plurality of intervals on the seat web 11.

The middle rail 2 of the support 1 is slidably embedded between two support side walls 12 of the support 1, at least one support side wall 12 is provided with a third concave part 14 which is concave relative to the support side wall 12, the two support side walls 12 are respectively provided with a third concave part 14 which is symmetrically arranged, and the third concave part 14 can adopt similar stamping with the first concave part 13 to realize the condition of improving the stress and be used for limiting the middle rail 2 to be separated from the support 1.

In order to further increase the load bearing capacity of the intermediate rail 2, the intermediate rail 2 has a longitudinally disposed intermediate rail web 21, and a fourth internal recess 23 is provided near the transition of the intermediate rail web 21 and the intermediate rail side wall 22, in a manner similar to the second internal recess 14 described above, and may also be used to strengthen the stress condition of the intermediate rail and increase its load bearing capacity.

Specifically, in the implementation process, the first concave portion 13, the second concave portion 14, the third concave portion 15 and the fourth concave portion 23 can be formed by pressing down through a pressing head, the concave size is 0.15mm-2mm, the first concave portion 13, the second concave portion 14, the third concave portion 15 and the fourth concave portion 23 can also be pressed down to a deeper size according to the process requirement, and the effect is better.
