Pressing type door lock

Abstract

The invention provides a pressing type door lock. The pressing type door lock comprises a shell, wherein the shell is arranged on an electric appliance door cover, an inserting groove allowing a doorhook to be inserted is formed in the shell, and a locking body which is provided with a locking body spring in a matched mode, an operation plate provided with a tension spring in a matched mode and aswing rod are arranged in the shell. The locking body is rotationally arranged in the shell, one end of the operation plate is rotationally arranged on the shell, and the other end of the operation plate is installed to the locking body in a matched mode; the swing rod is rotationally arranged below the locking body, a boss installed on the operation plate in a matched mode is arranged on the upper portion of the swing rod, and a swing hammer is arranged on the lower portion of the swing rod. When the door hook is inserted into the locking body and the swing hammer moves in the insertion direction of the door hook due to inertia, the boss moves towards one end close to the operation plate to interfere with the operation plate, and a positioning needle on the operation plate is prevented from acting. When a main door is closed, a middle door can be prevented from being opened suddenly, and the user experience degree can be improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of door locks for household appliances, in particular to a push-type door lock. [0003] 【Background technique】 [0004] Nowadays, push-type switches are used on many doors, such as filing cabinets, copiers and other office furniture, as well as bar doors on large-volume refrigerators. The existing push switches are generally divided into two types, one is the spring buckle type with simple structure, and the other is the touch switch with complex and delicate structure. The opening and closing of the door body. [0005] In order to solve the above problems, the application number is 201120164093.3, which proposes a door lock switch using a ratchet structure, which uses the intermittent motion characteristics of the ratchet to control the movement of the buckle in the card body. Compared with the traditional spring lock body structure, it is stronger, flexible and durable, but it still has some def...

[0005] In order to solve the above problems, the application number is 201120164093.3, which proposes a door lock switch using a ratchet structure, which uses the intermittent motion characteristics of the ratchet to control the action of the buckle in the card body. The buckle can flex freely and can well control the opening of the door body. Compared with the traditional spring lock body structure, it is stronger, flexible and durable, but it still has some defects in the process of use: when using the push-type door lock switch to lock the main door and the door in the door, when the door is closed For the main door, after the main door is closed in place, due to inertia, the door-in-door still has kinetic energy to move it inward, which triggers the unlocking of the push-type door lock switch, causing the door-in-door to suddenly open, affecting user experience
