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 hinge of the flap door 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 door is hinged to open and close, and the upper flap door opens at a certain angle Then it will automatically close due to its own weight, which cannot meet the needs of users

Embodiment Construction

[0018] The present invention will be further described below with reference to the drawings and embodiments.

[0019] See Figure 1-Figure 5 , The upturning effort-saving mechanism of the upturning device includes a fixing element 1, a connecting arm assembly, and a fixing seat 2. The fixing seat 2 can be turned and opened and closed on the fixing element 1 through the connecting arm assembly, and the fixing element 1 is provided with a first spring 3 and the second spring 4, the connecting arm assembly includes at least a first connecting arm 11, a second connecting arm 12, and a third connecting arm 13. One end of the first connecting arm 11 is connected to the second spring 4, and the middle part is hinged to the fixing element 1. , The other end is hinged with one end of the second connecting arm 12, the other end of the second connecting arm 12 is hinged with the middle of the third connecting arm 13, and an angle A is formed between the two, and one end of the third connecti...

Abstract

An upturning labor-saving mechanism of an upturning device, comprising a fixing element, a connecting arm assembly and a fixing seat, the fixing element is provided with first and second springs, and the connecting arm assembly includes at least first, second, and third connecting arms, Wherein the second connecting arm and the third connecting arm are hinged, and an angle A is formed between the two, one end of the first spring acts on the hinge of the first and second connecting arms, and the other end acts on the fixing element; the fixing seat is opposite The fixing element is flipped open, and at least when the included angle A is in the inferior angle, the opening force generated by the first spring is automatically opened on the fixing element, and the fixing seat is flipped and closed relative to the fixing element, and at least when the included angle A is in the superior angle, it passes through the first The spring generates a closing force and automatically closes on the fixed element; the second spring generates an opposite force to the first spring at least when the fixed seat is flipped relative to the fixed element and the included angle A is at a reflex angle, so as to partially offset the force produced by the first spring. Strong closing force, strong practicability.

Description

Technical field [0001] The invention relates to an upturning device, in particular to an upturning effort-saving mechanism for a furniture upturning device. Background technique [0002] Chinese Patent Document No. CN202039710U discloses an upturn door hinge on November 16, 2011. The curved end of the first rotating arm is rotatably connected with the base plate, and the curved end of the second rotating arm is rotatably connected with the base plate. Both ends of the above-mentioned connecting arm, which can coincide with the straight ends of the first and second rotating arms at the same time, are respectively rotatably connected with the straight ends of the first and second rotating arms, and the connecting arm is 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 air rod. The fixed rod of the air rod can be movably connected to the base plate. The base plate i...
