The Elastic Manipulation Structure of the Upturn Door of Furniture

Abstract

The invention discloses an elastic force manipulating structure of a tilt-up door of furniture, which comprises an upturning device, wherein the upturning device comprises a fixed seat, a hinge arm, a spring, a connecting arm assembly and an adjusting assembly which is used for adjusting the magnitude of opening and close force of the upturning device; the connecting arm assembly at least comprises a first connecting arm and a second connecting arm; one end of the first connecting arm is hinged to the fixed seat; the other end of the first connecting arm is hinged to one end of the second connecting arm; the other end of the second connecting arm is hinged to the fixed seat and / or the hinge arm; the first connecting arm and the second connecting arm are hinged by a first pin shaft; a groove is formed in the first pin shaft; one end of the spring acts on the groove; the other end of the spring acts on the second pin shaft of the adjusting assembly; the spring generates displacement relative to the fixed seat by the adjusting assembly under the effect of a tool, and finally, the magnitude adjustment of opening and closing force of the upturning device can be realized. The elastic force manipulating structure of the tilt-up door of furniture has the characteristics that the structure is simple and reasonable, the performance is reliable, the production is easy, the implementation is easy, the adjustment is rapid, the operation is convenient, the use range is wide, the opening and closing are smooth, the collision is small, the noise is low and the like.

Description

technical field [0001] The invention relates to a furniture upward flap, in particular to an elastic force control structure for a furniture upward flap. 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...

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 the elastic device to achieve buffering and damping, and the force during the closing movement or opening movement cannot achieve a uniform effect, and the elastic device 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.
