Abstract

The invention discloses a gear and rack driving type automatic locking mechanism, relating to a locking mechanism used for a file cabinet. The invention resolves the problems that the prior lock on the file cabinet can not realize the functions of automatic closing and locking, the prior locking mechanism is dumb when unlocked and locked. One end of a lock (6) is connected with the lower end of an upper connecting rod (5), the upper end of the upper connecting rod (5) penetrates a casing (9), the other end of the lock (6) is connected with a mechanism support (4), gears (2) and racks on a rack lever (3) are meshed, the gears (2) are meshed with hand pulling racks (1), an energy storage elastic part is connected with an energy storage elastic part connecting rod (4-3), and the lower end of the energy storage elastic part (8) is fixed on the casing (9). The gear and rack driving type automatic locking mechanism realizes that the door of the file cabinet can be closed and locked at the same time, and solves the problem of the rebounding of the cabinet door. The gear and rack driving type automatic locking mechanism has the advantages of flexible unlocking and locking, excellent stability, low cost and convenient unlocking and locking.

Description

technical field [0001] The invention relates to a locking mechanism for filing cabinets. Background technique [0002] Existing steel filing cabinets (iron cabinets) generally adopt manual methods such as picking hands or keys to open and close the cabinet door, and the lockset on the filing cabinet itself cannot realize the automatic door closing and locking function. If you want to automatically lock the cabinet door, it is generally realized by using an external force closing structure such as a closer (locking mechanism), but this increases the cost of the lock on the one hand, and the opening and closing of the cabinet door is not flexible enough; The general steel filing cabinet products are often not very firm in structure. If an external force closer is used, the stability of the cabinet will be affected. Contents of the invention [0003] In order to solve the problem that the lock on the existing file cabinet cannot realize the automatic door closing and locking...
