Abstract

The invention provides a door lock device. The door lock device comprises a shell and a base body; and the shell is installed outside the base body. The door lock device is characterized in that a driving plate, a locking plate and a connection rod are arranged in the shell; the driving plate and the locking plate are movably connected through the connection rod; under the effect of the connectionrod, the driving plate can control the locking plate to move; the locking plate is provided with a heart-shaped structure and a spring bolt; the heart-shaped structure is arranged on one side of thelocking plate, and matched with a positioning needle; and the spring bolt is arranged on the other side of the locking plate, and is matched with a door hook. The height of a door lock is effectivelylowered, the problem that an electric appliance door cover is too thick and heavy is solved, and the overall appearance is attractive; the driving plate is controlled to move through the door hook; and under the effects of the connection rod, the locking plate is driven for linkage, the locking plate can be used for locking the door hook, and door locking control is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of door locks for electrical equipment, in particular to a door lock device. 【Background technique】 [0002] When household appliances are working, the door cover should be locked for safety to prevent accidental opening. figure 1 As shown, the current upper cover type door cover lock structure has a door hook 104 on the door cover, and the door hook 104 cooperates with the existing door lock 103 to realize locking and unlocking actions; there are the following problems: [0003] The height L of this type of door lock is relatively large, resulting in a relatively thick door cover, which affects the overall appearance and cost of the home appliance. [0004] In order to solve the above technical problems, a door lock device with a more optimized structure is needed. 【Content of invention】 [0005] The purpose of the present invention is to solve the problems in the prior art, and propose a door lock de...
