Door body self-lock device and refrigerator

Abstract

The invention provides a door body self-lock device and a refrigerator. The door body self-lock device is used for the refrigerator, and a door body and a case body of the refrigerator are connected with each other through a hinge; the door body self-lock device comprises the hinge and a lock catch, wherein a locking pin and a spring which is always in a tensional state are installed on the hinge, the first end of the locking pin is rotatably connected with the hinge, the second end of the locking pin is provided with a first connecting portion, the first end of the spring is connected with the hinge, the second end of the spring is connected with the position, except the first end of the locking pin, of the locking pin, the spring can drive the locking pin to rotate, the hinge is provided with a limiting block used for limiting rotation angles of the locking pin, the lock catch is fixedly installed on the door body and provided with a second connecting portion, and the second connecting portion can be matched with the first connecting portion. The connection position of the first end of the spring and the hinge is located beyond the area through which the orthographic projection of the locking pin passes on the hinge along with rotation of the locking pin. Accordingly, by means of the technical scheme, it can be guaranteed that the refrigerator has a good thermal insulating property, and assisting force can be provided for a user when the door body is opened and closed.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a door body self-locking device and a refrigerator provided with the door body self-locking device. Background technique [0002] The refrigerator door and the refrigerator box are connected by hinges to realize free opening and closing. At present, there are two self-locking methods for refrigerators with self-locking function. One is to install magnetic strips in the door seal of the refrigerator. Attraction realizes self-locking, but the magnet will reduce the insulation performance of the door seal. The other is to install a door body self-locking mechanism on the refrigerator. Although this method can ensure the insulation performance of the refrigerator, it is affected by the locking pin and the lock of the self-locking mechanism (such as figure 1 As shown), the self-locking mechanism of the door body will only provide assistance to the user when closing the do...

The other is to install a door body self-locking mechanism on the refrigerator. Although this method can ensure the insulation performance of the refrigerator, it is affected by the locking pin and the lock of the self-locking mechanism (such as figure 1 As shown), the self-locking mechanism of the door body will only provide assistance to the user when closing the door, but will not provide assistance when opening the door, so that the user will feel that the whole process of opening the door is more laborious, which reduces the user's experience
