Refrigerator

Abstract

The invention discloses a refrigerator, and relates to the technical field of refrigerators. The refrigerator is used for solving the problem that opening of a refrigerator door is relatively laborious on the basis of realizing automatic closing of the refrigerator door of a refrigerator in the prior art. According to the refrigerator, a box body and a box door are hinged through a hinge, a shaftsleeve is fixedly connected with the box door, and an installation through hole is formed in the shaft sleeve; a transmission device is installed in the installation through hole; the transmission device comprises a hinge shaft fixed on the box body; a lower support is fixed on the hinge shaft, and wedge-shaped teeth are arranged on the upper end surface of the lower support; the hinge shaft is sleeved with an upper support, the lower end surface of the upper support is provided with a wedge-shaped groove corresponding to the wedge-shaped teeth, the wedge-shaped teeth consist of a top surfaceand two side surfaces, at least one of the two side surfaces of the wedge-shaped teeth is a spiral surface, and the spiral surface is used for guiding the upper support to spirally ascend or spirallydescend along the axis of the hinge shaft; the upper support is in sliding connection with the shaft sleeve through the guide part; a limiting block is fixedly arranged on the shaft sleeve; and an elastic part is abutted between the upper support seat and the limiting block.

Description

technical field [0001] The invention relates to the technical field related to refrigerators, in particular to a refrigerator. Background technique [0002] In the prior art, the door of the refrigerator is connected with the box body by a hinge. After placing or taking items, if people close the door of the refrigerator with less force, it is easy to cause the door of the refrigerator to not close properly. , will cause the cold air in the refrigerator box to be lost, causing the compressor of the refrigerator to work for a long time, consuming extra electric energy, and resulting in waste of electric energy. [0003] For this reason, the refrigerator in the prior art is provided with such as figure 1 As shown in the hinge, the hinge includes a shaft sleeve 01, an elastic part 02 is arranged inside the shaft sleeve 01, an end cover 03 is provided at the upper end of the elastic part 02, a screw 04 is provided at the upper end of the end cover 03, and a screw 04 is provided...
