Description

Torsion-adjustable hinge and cabinet body assembly Technical Field The utility model relates to the technical field of hinges, in particular to a torsion-adjustable hinge and a cabinet body assembly. Background This section provides only background information related to the present application so as to enable those skilled in the art to more thoroughly and accurately understand the present application, and is not necessarily prior art. In modern daily life, hinges are widely used in connection and opening and closing mechanisms of various container furniture and electronic equipment. For traditional hinges, the torsion of the hinge cannot be adjusted, and the weight of a door body used by the hinge is different, so that the opening and closing efficiencies of the hinge are different, and the application range of the hinge is limited. Therefore, a merchant wears an adjusting screw on the top wall of the hinge arm, the bottom of the adjusting screw is abutted against the torsion arm of the hinge torsion spring, and when the adjusting screw is driven to move up and down, the adjusting screw can compress or release the torsion arm of the torsion spring to adjust the torsion. However, when the arrangement mode is adopted, as the adjusting screw is of an elongated strip-shaped structure, the contact area between the adjusting screw and the torsion arm of the torsion spring is small, in the process of driving the adjusting screw to lift, the adjusting screw and the torsion arm can be separated, so that torsion adjustment of the torsion spring is invalid, and secondly, the adjusting screw is penetrated at the top of the hinge arm to influence the overall appearance of the hinge, particularly, under the condition of poor surface treatment of the adjusting screw, the metal texture of the screw is abrupt, so that the overall attractiveness is greatly reduced.
