Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a stainless steel hinge with a buffering function. Background Technique

[0002] A stainless steel hinge is a mechanical device mainly used to connect two solids and allow relative rotation between them. The buffering principle mainly depends on the built-in torsion spring and hydraulic cylinder. When closing the hinge, the pressure generated by the distortion of the built-in torsion spring forces the hydraulic oil in the cylinder to flow through the small holes in the piston. Since the aperture of the oil hole is small, the oil flow rate is slow, which hinders the torsion spring from closing the door quickly, thus realizing the buffering effect of hinge closing.

[0003] At present, when a stainless steel hinge with a buffering structure is used at the closing structure, the built-in buffering structure of the hinge is used for buffering the closing of the closing structure. If the rotational force received by the hinge is too large, the built-in buffering structure of the hinge often cannot effectively buffer the large driving force, so the impact damage caused by the closing of the door body of the closing structure cannot be avoided. Therefore, we propose a stainless steel hinge with a buffering function. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a stainless steel hinge with a buffering function. A buffering mechanism is arranged at the main leaf plate and the auxiliary leaf plate installed at the hinge body. The buffering mechanism forms an external supplementary buffering structure outside the main leaf plate and the auxiliary leaf plate. The rubber blocking strip of the main leaf plate can hit the L-shaped rubber blocking seat below the auxiliary supporting strip. At this time, an elastic metal plate in the L-shaped rubber blocking seat provides resistance support. Then, after the L-shaped rubber blocking seat contacts the rubber blocking strip, elastic deformation occurs to unload the force and buffer. Moreover, the original torsion spring and hydraulic cylinder in the hinge body between the main leaf plate and the auxiliary leaf plate can also buffer the closing force of the main leaf plate and the auxiliary leaf plate. With the cooperation of the buffering mechanism and the original buffering structure of the hinge body, the buffering ability of the stainless steel hinge when subjected to external forces is effectively improved, and the problems in the background technique can be effectively solved.
