Refrigerator hinge

Abstract

The invention relates to the technical field of refrigerator hinges, and in particular to a novel refrigerator hinge. The refrigerator hinge comprises a hinge head, a hinge base, a movable shaft, a movable shaft sleeve, a fixed shaft, a rocker, a spring, an upper spring base, a lower spring base and a supporting base. An interference fit assembly is composed of the rocker, the lower spring base and the supporting base, and in other words, when hinge assembling is finished, prefabricated damping force is formed between the rocker and the lower spring base; and when a door body is opened or closed, sliding friction force is produced on the contact face of the rocker and the lower spring base, the sliding friction force can effectively balance elasticity of the spring, reduce the door body sudden accelerated rotation caused by the sudden change of the elasticity of the spring and reduce the door body impact force, and the service life of the hinge and the door body is prolonged. When the door body is stopped in a suspended manner, the static friction force is generated on the contact face of the rocker and the lower spring base, and due to the fact that the static friction force can be changed along with the pressure of the door body and the like, the suspended stopping angle range of the door body can be effectively enlarged, and therefore the refrigerator hinge can be suitable for various door body structures.

Description

technical field [0001] The invention relates to the technical field of refrigerator hinges, in particular to a novel refrigerator hinge. Background technique [0002] The hinge is usually arranged at the junction of the cabinet body and the door body, and provides the strength to support the door body through the compression of the spring in the hinge. [0003] The existing freezer hinge has the following disadvantages: [0004] 1. When the door body opens beyond a certain angle, such as when the door body opening angle is in the range of 35°-75°, the elastic force generated by the spring can easily accelerate the door body to rotate, and when the door body rotates to the stop point, it will stop suddenly. A large impact force is generated, causing damage to the door body, box body and hinges, and reducing the service life; [0005] 2. The hovering angle of the existing door body is small, which is inconvenient for users to use; [0006] 3. There are many types of existin...

Problems solved by technology

[0004] 1. When the door body opens beyond a certain angle, such as when the door body opening angle is in the range of 35°-75°, the elastic force generated by the spring can easily accelerate the door body to rotate, and when the door body rotates to the stop point, it will stop suddenly. A large impact force is generated, causing damage to the door body, box body and hinges, and reducing the service life;

[0005] 2. The hovering angle of the existing door body is small, which is inconvenient for users to use;

[0006] 3. There are many types of existing doors, and the specifications and weights are inconsistent. It needs to be equipped with a variety of hinge structures with different elastic forces to support the door body, and the hinges have poor versatility.

During the up-and-down movement of the guide plate of the above-mentioned balance hinge, it is necessary to ensure that there is friction between the guide plate and the axial through groove, and there must be relative motion between the conical circular platform and the conical hole, resulting in the friction between the spring lower seat and the hinge lower shell. It is easy to loosen, and over time, it will affect the service life of hinges and doors

Moreover, the frictional force generated between the axial through groove of the balance hinge and the guide plate is unstable, and the frictional force is heavily dependent on the elastic force of the spring, so the balancing effect will be affected.
