Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: a drawer structural member comprises a lower drawer 1 and an upper drawer 2, wherein a guide rail 3 is arranged on the side surface of the upper drawer 2, and a stop block 5 is arranged on the side surface of the lower drawer 1;

the shell 7 is positioned on the side surface of the lower drawer 1, the lock tongue 6 is slidably connected in the shell 7, the lock tongue 6 is positioned on the side surface of the stop block 5, when the lower drawer 1 and the upper drawer 2 are closed, the lock tongue 6 is blocked on the side surface of the stop block 5, a control column 8 positioned on the upper surface of the guide rail 3 is arranged on the surface of the lock tongue 6, the control column 8 is circular, the friction between the control column 8 and the guide rail 3 is reduced, and the control column 8 can be replaced by a roller;
