Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and in particular relates to a hardware hinge with an anti-deformation function. Background Art

[0002] Hinges are primarily used to connect cabinet doors and cabinet bodies. Common materials include stainless steel and iron. They are mechanical devices used to connect two solid objects and allow relative rotation between them. Hinges can be categorized by material, such as stainless steel hinges or iron hinges. Stainless steel hinges are more common in many applications due to their corrosion resistance. Iron hinges, on the other hand, are also used in less demanding applications due to their lower cost. Hydraulic hinges, a special type of hinge, use an internal hydraulic mechanism to provide a cushioning effect when the door closes.

[0003] From the perspective of existing technology, existing hinges only use a rotating shaft support, and two sets of shaft sleeves drive the hinge plates to rotate with each other to achieve the purpose of allowing the installed objects to rotate with each other. After long-term use, due to the weight of the object and the torque of the external object, friction and deformation between the shaft sleeves, as well as deformation between the shaft sleeves and the rotating shaft are often caused. If they are not replaced in time, the use will be seriously affected. Therefore, a hardware hinge with anti-deformation function is needed.
