TECHNICAL FIELD

The present disclosure relates to the technical field of storage devices, and in particular to a detachable support rail for a rack and a rack.

BACKGROUND

Independent storage units of the rack serve as movable storage devices to classify and store items. The common storage units are usually used with the rack through multi-section slide rails, support plates or support rails. The support rail for the rack is configured to support a bottom of the storage unit, such that the storage unit is placed in the rack movably. The support rail is often designed as a bar component with an L-shaped cross-section. This design provides the bottom support for the storage unit, while ensuring the movement along a fixed direction toward the user. However, the support rail for the storage unit of the rack in existing markets is usually fixed to a rack body by welding or screw fastening. For the welding, the product takes up a large space in the sales package, which is not convenient for transportation and handling, and is prone to damage in the transportation. For the screw fastening, the product is mounted by the user with a tool cumbersomely.

In view of this, to provide an easy-to-mount support rail with a sufficient structural strength and an assorted rack has become a problem to be solved urgently at present.
