Description

Technical Field

[0001] The utility model relates to the technical field of safe boxes, in particular to a safe box cabinet, and specifically to an integrated locking mechanism for a drawer and a door of a safe box cabinet. Background Art

[0002] With the continuous improvement of people's living standards, safe boxes or safe cabinets have widely entered the lives of the general public. People can put precious jewelry, cash, and important bills and materials in the safe box. However, traditional safe boxes or cabinets generally have a single-door structure and use a bolt mechanism to lock the door of the box cabinet. The bolt is generally arranged on one side of the lower cabinet door and is inserted and connected to the door frame of the box cabinet. Inside the box cabinet, there are often layers or drawer structures to classify and place the items for easy access. In this way, when operating, it is necessary to first open the door of the box and then open the drawer to take the items, and the operation is not convenient enough. For this reason, there are also safe boxes with an upper drawer and a lower door on the market. Such safe boxes generally adopt two sets of mechanisms to separately control the opening and closing of the drawer and the door. These two sets of mechanisms have the following characteristics:

[0003] First, the structural designs are inconsistent. The locking mechanism of the drawer is generally a one-way design, and the opening and closing of the lock are realized by cooperating with the lock hook and spring at the tail of the drawer. That is, when the motor rotates, it drives the structural member to release the lock hook, and the drawer pops out under the action of the spring; after the motor returns to its original position, the user pushes the drawer to close it in place, and the lock hook at the tail inserts into the buckle to achieve automatic locking. The locking mechanism of the door is basically the same as that of an ordinary single-door safe box.

[0004] Second, the working positions are different. The locking mechanism of the drawer is generally located at the tail of the drawer and is fixed to the box body; the locking mechanism of the door is located on the door panel.

[0005] Third, their mechanical parts are completely independent of each other and are separately controlled by the same electronic control module. However, due to the long distance between them, they need to be installed and wired separately.

[0006] Therefore, the existing method of two sets of locking mechanisms has a relatively complex structure. Not only are there many parts, which is not conducive to production and processing, but also the two sets of locking mechanisms are independent of each other, which is not conducive to installation and internal wiring. Content of the Utility Model

[0007] The primary technical problem to be solved by the utility model is to provide an integrated locking mechanism for a drawer and a door of a safe box cabinet that is simple and reasonable in structure and convenient for assembly. The locking mechanisms of the drawer and the lower cabinet door are combined in a fixed box, which is convenient for installation, and at the same time, part of the wiring is saved, reducing the cost.

[0008] Another technical problem to be solved by the present utility model is to provide an integrated locking mechanism for the drawer and the cabinet door of a safe cabinet, which has a simple and reasonable structure and is convenient for assembly.
