Description

Technical Field

[0001] The present application relates to the technical field of torque testing, and in particular to a torque testing device. Background Art

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. Hinges can be made of movable components or foldable materials. Hinges are often installed on cabinets and are classified by material into stainless steel hinges and iron hinges. To provide better comfort, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is that they provide a buffering function when the cabinet door closes, minimizing the noise caused by the door colliding with the cabinet body when closing. Camera viewfinder hinges are a type of hinge and require torque testing before leaving the factory.

[0003] The existing hinge fixing method is relatively complicated when performing torque testing, which leads to low efficiency of hinge torque testing. This is mainly because the existing hinge fixing method mostly uses multiple bolts for locking, which takes a certain amount of time to install or remove the hinge. Utility Model Content
