Support of refrigerator door and door lock device

Abstract

The invention discloses a supporting and a door locking device of a refrigerator door, comprising a refrigerator body and a refrigerator door; a refrigerator door supporting and a door locking integrate structure are arranged at the lower part of the refrigerator door, the door locking integrate structure comprises a framework fixed on a rim of the refrigerator, to sustain the possible sinking ofthe refrigerator door and lighten the force of a door hinge and prolong the service life of the refrigerator door. The interior of the framework is provided with the door locking device to lock the refrigerator door after the refrigerator door is closed and prevent the refrigerator door from being opened by other persons or children. The door locking device comprises a door lock, a door lock fixing board, a connecting rod, a sleeve, an axis pin, a pin fixing board, a pin, and a guide sleeve that are sequentially connected with the door lock. When the door lock is closed, a key can rotate the door lock and lift the pin, when the lock is opened, the key can drop the pin. The integrated structure that combines the supporting and the door lock of the refrigerator door of the invention obviously solves the disadvantages of the prior art that the refrigerator has only a door lock and does not have a supporting door.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a support and a door lock device for the door of the refrigerator. Background technique [0002] The support and door lock device of the freezer door of the present invention refers to a freezer similar to a refrigerator. In household appliances such as refrigerators, in order to prevent children from opening the door, it is necessary to use locks. This type of locks generally has the characteristics of small size and multiple locks can be opened by the same key. There is a kind of refrigerator or freezer door lock on the market now, and it comprises lock end, lock cylinder and dead bolt, and the inner wall of lock end is provided with limit card slot, and lock cylinder is provided with copper bar and spring, and lock cylinder wall is provided with narrow slot. slit, the copper rod is connected with a bolt, the bolt passes through the slit on the lock cylinder, and its end fits with the limit s...

Problems solved by technology

[0008] Although this kind of refrigerator door lock has a simple structure, it only relies on its suction cup to fix the fixing seat on the side where the refrigerator door is opened, and its stability is relatively poor. Due to the limited adsorption force, it is easy to change position, causing inconvenience to use.

[0009] In the above-mentioned prior art, the refrigerator door lock used as a freezer door lock has the disadvantages that the structure is relatively complicated, or the structure is simple, but the stability is relatively poor.

In addition, the existing technology only has the function of locking the door, but has not considered the supporting function of the door. The possible sinking of the refrigerator door or freezer door will increase the force on the door hinge, resulting in a reduction in the service life of the door hinge.
