Door lock device capable of saving labor during door closing

Abstract

The door lock device comprises an upper shell, a lower shell and a locking body, a mounting cavity is formed in a shell formed by the upper shell and the lower shell, the locking body is arranged in the mounting cavity, a lock hole allowing a door hook to be inserted is formed in the upper shell, and the door lock device further comprises a driving plate and a spring. A driving plate is arranged on one side of the locking body, a spring is arranged on the side, back on to the locking body, of the driving plate in a matched mode, the spring exerts acting force abutting against the locking body on the driving plate, the locking body is provided with an equidistant upper arc face and a variable-pitch lower arc face, and when the driving plate makes contact with different positions of the equidistant upper arc face, the variable-pitch lower arc face abuts against the variable-pitch upper arc face. The distance between the driving plate and the locking body shaft of the locking body is kept unchanged, and when the driving plate makes contact with the variable-pitch lower arc face, under the action of the spring, acting force for assisting in closing the door is applied to the locking body. The door lock device is small in door closing force, convenient to operate and capable of resetting after door closing after false triggering, and maintenance is not needed.

Description

【Technical field】 [0001] The invention relates to the technical field of door locks, in particular to a door lock device with energy-saving door closing. 【Background technique】 [0002] At present, the door cover of household appliances is generally equipped with a door lock device, and the locking force provided by the door lock device keeps the door cover closed after the door is closed. When opening the door, the user can forcibly open it. However, the door lock devices currently on the market have the following problems: [0003] 1. The closing force is relatively large, and the user's closing experience is not good. [0004] 2. After the door lock is accidentally triggered (especially when children are playing with other tools), the door will not close when it is closed again, and it needs to be solved by after-sales maintenance. 【Content of invention】 [0005] The purpose of the present invention is to solve the problems in the prior art, and propose a door lock d...
