Abstract

The invention discloses a damping hinge. The damping hinge comprises an outer cylinder; a rotating shaft is arranged in the outer cylinder; the rotating shaft is provided with damping blades, a control hole and a placing tank; the tails of the damping blades are arranged in the placing tank; a through hole is formed in the bottom of the placing tank; each damping blade is provided with a connecting rod penetrating through the through hole; the connecting rod and the through hole are slidingly arranged; an annular groove is formed in the part, extending into the control hole, of the front partof the connecting rod; a clamping ring sleeves the annular groove; the connecting rod is provided with a return spring between the clamping ring and the inner wall of the control hole; a control rod with a control groove is arranged in the control hole; the front end of the connecting rod is ejected in the control groove; and the depth of the control groove is gradually changed from deep to shallow. The damping hinge has the following advantages that the control rod is adjusted to enable the head of the connecting rod to slide in the control groove, so that the distances from the top ends of the blades to the rotating shaft are controlled, the contact areas of the damping blades and damping oil are adjusted, and adjustment of the damping force is realized; and through the return spring, recovery of the damping blades is realized.

Description

technical field [0001] The invention relates to a damping hinge. Background technique [0002] The damping hinge is a commonly used hardware used for the connection of two objects, such as doors and cabinets. It is generally composed of an outer cylinder and a rotating shaft. The outer cylinder is filled with damping oil. The oil interacts to achieve the damping effect, but the existing damping hinges often cannot adjust the damping force. Contents of the invention [0003] The purpose of the present invention is to provide a damping hinge, which can effectively solve the problem that the existing damping hinge cannot adjust the damping force. [0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a damping hinge, including an outer cylinder, the two ends of the outer cylinder are closed, a cavity is provided in the outer cylinder, and damping oil is provided in the cavity, so The volume of th...
