Description
Technical field
The utility model relates to the elastic component syndeton of a kind of hinge for furniture, particularly a kind of hinge.
Background technology
Existing furniture hinge spring connecting structure comprises fixed arm 21 ', interior swing arm 22 ', outer swing arm 24 ' and movable cup 25 ' referring to Figure 25-Figure 27.Outer swing arm 24 ' rear and front end is hinged with movable cup and fixed arm respectively through bearing pin; Interior swing arm 22 ' is positioned at outer swing arm below, and front end and middle part are hinged with movable cup and fixed arm respectively through bearing pin.Be with the torsion spring 23 ' that movable cup is produced closing function power on the hinged bearing pin of outer swing arm and fixed arm.Outer swing arm 24 ' is the channel-section steel type, and the rear end end face extends the cover plate 24.1 ' that is used to hide torsion spring, forms step 24.2 ' between cover plate both sides and the outer swing arm both sides; Torsion spring 23 ' upper end is resisted against on the step.When movable cup 25 ' was closed, the torsion spring upper end was 75 °-90 ° with the contact that outer swing arm is joined to the line of torsion spring central point and the angle β of movable cup mounting plane.The active force of the hinge of this structure in switching process is mainly derived from this torsion spring; And, from above-mentioned angle β can judge hinge in open mode to the closed condition process, the power when torsion spring recovers deformation only is used to drive outer swing arm rotation less than 60%; Therefore; The utilization rate very low (it is little to act on the active force that outer swing arm is closed, and other component is big) of the power when torsion spring discharges, the steel wire diameter of torsion spring must be in rated range (more than diameter 1.5mm); Just can make hinge when opening to certain angle, pass through torsion spring active force automatic fully-open, perhaps when being closed to certain angle, close fully automatically through the torsion spring active force.
In addition, since life-span of torsion spring depend primarily on the ratio of torsion spring external diameter and the external diameter of the steel wire that is used for the winding torsion spring.Continuously hinge being carried out in the fatigue test process of folding, when said this ratio reached requirement, torsion spring can be resisted lasting folding test; When said this ratio can not reach requirement, torsion spring will cause dynamics to weaken even ruptures because of metal fatigue.Hinge in the said structure, because torsion spring receives the restriction of installation site, its external diameter can not increase, if increase the torsion spring external diameter by force, then raises the cost greatly; In addition, the utilization rate of the power when discharging owing to torsion spring is low, so the gauge of wire of torsion spring must be in rated range; The factor of comprehensive two aspects has finally caused torsion spring in the fatigue test of folding continuously, causes product function to lose efficacy, and brings potential safety hazard.
