Abstract
The utility model relates to a spring connection structure for a furniture hinge, which comprises a fixed arm and a movable cup holder, wherein the movable cup holder is hinged with the fixed arm at least through an outer swinging arm and an inner swinging arm; the front end of the outer swinging arm is hinged with the movable cup holder, and the rear end of the outer swinging arm is hinged with the fixed arm directly or is hinged with the fixed arm through more than one linking arm; a torsion spring that can generate an acting force to close the movable cup holder is arranged at the lower part of 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 of the torsion spring is connected with other parts except the outer swinging arm; the top surface of the inner end of the outer swinging arm also extends out of a cover board; and the upper end of the torsion spring of the outer swinging arm is connected with the end part of the cover board. When the movable cup holder is closed, the included angle Alpha formed by a mounting plane of the movable cup holder and a line that is determined by a contact point and a central point of the torsion spring ranges from 200 to 70 degrees, wherein the upper end of the torsion spring and the cover board of the outer swinging arm are connected through the contact point. By decreasing 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, the spring connection structure can prolong the service life of the torsion spring, and can ensure that the hinge can be opened completely or closed completely through the acting force of the torsion spring when the hinge is opened or closed to a certain angle under the circumstances of not changing the external diameter of the torsion spring.
Description
Technical field
The utility model relates to a kind of hinge for furniture, particularly a kind of furniture hinge spring connecting structure.
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 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 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 1.5mm; 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.

Described outer swing arm is the channel-section steel type, and the side, front and back end is provided with pin-and-hole, and hinged by bearing pin and movable cup and fixed arm respectively; Cover plate is tabular or arc; Torsion spring set is located on the bearing pin that is positioned at outer swing arm rear end, and the upper end joins with patch ends bottom surface or end edge.
Swing arm is positioned at below the outer swing arm in described, and interior swing arm front end and middle part are hinged by bearing pin and movable cup and fixed arm respectively; Also be provided with damper in the fixed arm, the piston rod of damper is connected transmission with interior swing arm the inner by centering block, and piston rod afterbody and fixed arm are hinged; The centering block middle part is hinged by bearing pin and fixed arm; The bearing pin at torsion spring lower end and fixed arm, inner rocker arm or inner rocker arm middle part joins.
When described movable cup was closed, the torsion spring upper end was-200 °～70 ° with the contact that outer swing arm cover plate joins to the line of torsion spring central point and the angle α of movable cup mounting plane.
Described angle α is 0～65 °; Perhaps, angle α is 0～45 °; Perhaps, angle α is 0～20 °.
Rounded, trapezoidal, the square or hexagon of the section of steel wire of described torsion spring, the steel wire maximum outside diameter is than below the conventional little 0.1mm.
The utility model is under the situation that does not change the torsion spring external diameter, by dwindling the torsion spring gauge of wire, and the position of torsion spring and outer swing arm contact point, improve torsion spring in the time of the life-span thereby reach, improved the effective rate of utilization (being more than 1.5 times of prior art) of the power when torsion spring recovers deformation, guarantee that hinge passes through torsion spring active force automatic fully-open when opening to certain angle, perhaps close by the torsion spring active force automatically fully when being closed to certain angle.It is simple and reasonable,, long service life, easy for installation, cost is low, applicable to multiple hinge (especially being provided with the hinge of damper).
