A damper opening and closing angle changing mechanism of a hinge

Abstract

A damper opening and closing angle varying mechanism of a hinge comprises a blocking element, a connection element and a lever element which are in hinge fit with one another. A damper is arranged between the blocking element and the connection element. One end of the damper is rotationally arranged on the blocking element, and the other end of the damper abuts against the connection element. The connection element, the lever element and the damper are linked with one other relative to the blocking element when the hinge is opened or closed. When the hinge is closed by at least one certain angle, the lever element acts on the damper and drives the damper to slide on the connection element in a limited mode, the damper is compressed and generates damping force, and thus, damped closing of the hinge is achieved. Through the structure improvement, the damper opening and closing angle varying mechanism of the hinge has the characteristics that the structure is simple and reasonable, safety and reliability are achieved, production and implementation are easy, adjustment is fast, operation is convenient, the service life is long, practicability is high, and the opening and closing process is labor-saving, smooth, small in collision and low in noise.

Description

technical field [0001] The invention relates to a hinge damper opening and closing angle changing mechanism. Background technique [0002] The Chinese patent document number is CN202039710U, which discloses a hinge on November 16, 2011. The curved end of the first rotating arm of this structure is rotatably connected to the base plate, and the curved end of the second rotating arm is rotatably connected to the base plate. The two ends of the above-mentioned connecting arms that can overlap with the respective straight ends of the first rotating arm and the second rotating arm at the same time are rotatably connected with the respective straight ends of the first rotating arm and the second rotating arm respectively, and the connecting arms are located at the first Between the rotating arm and the second rotating arm, the bent end of the first rotating arm is hinged with the free end of the movable rod of the gas rod, and the fixed rod of the gas rod can be movably connected ...

Problems solved by technology

It is said that this structure can reduce noise, and the closing or opening movement of the cabinet door is more flexible. During the movement of the cabinet door, the overall translational movement can avoid the situation that ordinary cabinet doors may hit the head; however, the upper The flap hinges only use elastic components to achieve buffering and damping, and the force during the closing or opening movement cannot achieve a uniform effect, and the elastic component has a large friction force and high noise when the upper flap is hinged to open and close, which cannot meet the needs of users.
