Abstract
The invention relates to a furniture hinge spring connecting structure and a method for prolonging service life thereof. The furniture hinge spring connecting structure comprises a fixed arm and a movable cup seat, wherein the movable cup seat is connected with the fixed arm at least by an outer swinging arm and an inner swinging arm; the front end of the outer swinging arm is articulated with the movable cup seat, and the rear end is articulated with the fixed arm in a direct way or by more than one connecting arm; a torsion spring which applies closed acting force on the movable cup seat is also arranged below the rear end of the outer swinging arm; the upper end of the torsion spring is connected with the outer swinging arm, and the lower end is connected with parts except for the outer swinging arm; and when the movable cup seat is closed, an included angle alpha of the installation plane of the movable cup seat and a connecting line between a connecting contact point of the upper end of the torsion spring as well as the outer swinging arm and a central point of the torsion spring is between negative 200 degrees and 70 degrees. The invention achieves the aim of improving the service life of the torsion spring by reducing the diameter of a steel wire of the torsion spring and the position of the contact point of the torsion spring and the outer swinging arm without changing the outer diameter of the torsion spring and ensures that a hinge is automatically completely opened or completely closed by the acting force of the torsion spring when opened or closed to a certain angle.
Description
Technical field
The present invention relates to a kind of hinge for furniture, the method that particularly a kind of furniture hinge spring connecting structure and application life thereof prolong.
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 Fig. 1-Fig. 3.Outer swing arm 24 rear and front ends are hinged with movable cup and fixed arm respectively by 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 by 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 ends are 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, power when torsion spring recovers deformation only is used to drive outer swing arm less than 60% and rotates, therefore, the utilization rate of the power when torsion spring discharges is very low, and (it is little to act on the active force that outer swing arm is closed, other component is big), the steel wire maximum gauge of torsion spring must be more than 1mm, 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 by 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 is being carried out in the life test process of folding, when ratio greater than 4 the time, torsion spring can be resisted the folding test more than 50,000 times, can meet index; When ratio less than 4 the time, torsion spring will disconnect because of metal fatigue, thereby causes product rejection.Hinge in the said structure, because torsion spring is subjected to the restriction of installation site, its external diameter can not increase; In addition, the utilization rate of the power when discharging owing to spring is low, so the gauge of wire of torsion spring must be more than 1mm; The factor of comprehensive two aspects has finally caused torsion spring in the continuous operation life test, generally then can scrap with interior at 50,000 times.
