Description

Novel hinge structure

Technical Field

The utility model relates to a novel hinge structure.

Background

Hinges are mechanical devices used to connect two solid bodies and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material. The hinges are mainly arranged on doors and windows, and more hinges are arranged on cabinets and are mainly classified into stainless steel hinges and iron hinges according to materials; the hydraulic hinge (also called damping hinge) is also provided for people to enjoy better, and is characterized in that the hydraulic hinge has a buffering function when the cabinet door is closed, and the noise generated by collision between the cabinet door and the cabinet body when the cabinet door is closed is reduced to the greatest extent.

The mechanical hinge in the prior art is most widely applied, the structure is simplest, and the failure rate is lower. However, in practical application, it is found that the assembly difficulty is high, and after the assembly is completed, the hinge shaft is slender, so that after the hinge is heavily used for many times, the position of the hinge shaft is deformed, the rotation resistance of the hinge is increased, and noise is generated.

Based on the above problems, we have designed a new hinge structure with high structural strength and easy assembly.
