An adjustable upturning labor-saving mechanism of an upturning device

Abstract

The invention provides an adjustable upturning labor-saving mechanism of an upturning device, which comprises a fixed element, a connecting arm component and a fixed seat, wherein the fixed element is provided with a first spring and a second spring; the connecting arm component at least comprises a first connecting arm, a second connecting arm and a third connecting arm; the second connecting arm is articulated with the third connecting arm, and an included angle A is formed between the second connecting arm and the third connecting arm; one end of the first spring acts on the articulated part of the first connecting arm and the second connecting arm, and the other end of the first spring acts on the fixed element; the fixed seat can be overturned and opened relative to the fixed element and generates opening action force through the first spring at least when the included angle A is an inferior angle so that the fixed seat is automatically opened on the fixed element; the fixed seat can be overturned and closed relative to the fixed element and generates closing action force through the first spring at least when the included angle A is a reflex angle so that the fixed seat is automatically closed on the fixed element; the second spring is at least overturned and moved, relative to the fixed element, on the fixed seat and generates opposite action force to the first spring when the included angle A is a reflex angle; and the fixed element is provided with an adjusting element for adjusting the magnitude of the action force of the second spring, so that the practicability is strong.

Description

technical field [0001] The invention relates to an upturning device, in particular to an adjustable upturning labor-saving mechanism for 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
