Description

Technical Field

[0001] The utility model relates to the technical field of bracket slide rails, and specifically relates to a bracket slide rail. Background Art

[0002] After a vertical cabinet is assembled, it is necessary to set corresponding bracket slide rails for the equipment arranged in the height direction of the vertical cabinet. The bracket slide rails play a role in supporting the equipment and facilitating the pulling out of the equipment from the inner cavity of the cabinet. For the existing bracket slide rails, they are generally adapted and manufactured according to the depth of the vertical cabinet, which leads to the need for different lengths of bracket slide rails for each vertical cabinet with different depths, easily resulting in high assembly costs. Moreover, the convex mechanisms for locking with the positioning holes of the vertical cabinet on the existing bracket slide rails are all cylinders. In actual use, when the positioning holes of the vertical cabinet are square holes, there will still be a gap between the cylinder and the square hole, which leads to a risk of shaking of the bracket slide rail. Therefore, there is an urgent need to develop a bracket slide rail with good versatility and capable of adapting to different-shaped positioning holes. Summary of the Invention

[0003] Aiming at the above problems, the utility model provides a bracket slide rail, which has a simple structure, can be assembled with vertical cabinets of various depths, and can be stably positioned with square holes or round holes to ensure the reliable placement of the bracket slide rail.
