Acting force regulating mechanism of furniture upturning device

Abstract

The invention discloses an acting force regulating mechanism of a furniture upturning device. The acting force regulating mechanism comprises a fixed element, a connecting arm assembly and a fixed seat, wherein the fixed seat is overturned and opened/closed on the fixed element through the connecting arm assembly; the fixed element is provided with a first spring and second spring; one end of the first spring and one end of the second spring are respectively connected with the fixed element, and the other end of the first spring and the other end of the second spring are respectively connected with the connecting arm assembly; the fixed element is also provided with a regulating assembly for regulating an acting force of the second spring, and the regulating assembly at least comprises a fixed frame, a sliding element, a pushing element and a regulating screw; and a regulating action part of the regulating screw is acted through a tool or manually, the regulating screw is located and rotates relative to the fixed frame, drives the sliding element and the pushing element to displace on the fixed frame and releases or compresses the second spring so as to regulate the acting force of the second spring. The acting force regulating mechanism has the characteristics of simple and reasonable structure, safety and reliability, simplicity in production and realization, high regulation speed, convenience in operation as well as labor saving, smoothness, little collision, low noise and the like during starting/stopping.

Description

technical field [0001] The invention relates to a furniture upturning device, in particular to an active force adjustment mechanism of the furniture upturning device. 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, ...

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 hinge only realizes buffering and damping through the elastic device, 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, and the upper flap opens at a certain angle Afterwards, it will automatically close due to its own weight, without adjustment function, which cannot meet the needs of users
