Hinge device and refrigerator

Abstract

The invention provides a hinge device and a refrigerator. The refrigerator comprises a refrigerator body and a door body rotationally connected with the refrigerator body. The hinge device for the refrigerator comprises an upper chain base, a lower hinge base, a pull rod, a spring base and a spring, wherein the upper chain base and the lower chain base are fixedly connected with the door body andthe refrigerator body separately; the pull rod comprises a matching part in sliding connection with the upper chain base; the spring base is fixedly arranged at the end, away from the upper chain base, of the pull rod; the two ends of the spring abut against the lower hinge base and the spring base separately; and when the door body of the refrigerator is closed, the upper hinge base rotates alongwith the door body, the upper hinge base drives the pull rod to move due to sliding connection with the matching part, and the spring base moves towards the upper hinge base along with the pull rod so that the spring can be compressed. By means of the technical scheme, the end, abutting against with the spring base, of the spring has a high degree of freedom, the spring can be automatically amended when the spring base offsets, the possibility of occurrence of spring twisting is reduced while the door closing speed is controlled, and the service life of the spring can be prolonged conveniently.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a hinge device and a refrigerator. Background technique [0002] Due to the effect of the gravity of the door itself when the freezer door is closed, the door often closes faster, the impact force of the door on the freezer cabinet is greater, and the noise of closing the door is louder. To solve the problem of fast door closing speed and high noise, existing freezer hinges generally adopt traditional methods such as adding damping components and selecting high-quality springs, which lead to complicated hinge structure and high cost, and have not fundamentally solved the problem. At the same time, the spring tends to twist during the process of closing the door of the refrigerator, which reduces the life of the spring. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. ...

Problems solved by technology

[0002] When the freezer door is closed, due to the effect of the door's own gravity, the door often closes faster, the impact force of the door on the freezer body is greater, and the noise is louder when closing the door

In order to solve the problems of fast door closing speed and high noise, existing refrigerator hinges generally adopt traditional methods such as adding damping components and selecting high-quality springs, which lead to complicated hinge structure and high cost, and have not fundamentally solved the problem

At the same time, the spring tends to be distorted during the closing process of the refrigerator, reducing the life of the spring
