A spring for a door hinge and a hinge

Abstract

The utility model relates to hinge technical field, specifically disclose a kind of elastic member and hinge for door hinge, wherein, elastic member includes hollow axle joint part, first pressure arm is inclined and extended from one end of axle joint part, second pressure arm is inclined and extended from the other end of axle joint part, the V-shaped structure is formed between first pressure arm, axle joint part and second pressure arm, first pressure arm end is equipped with arc bending part, and the arc surface of the arc bending part is projected to V-shaped outside and forms pressure curve, and the outer convex arc surface of arc bending part is configured to pressure curve.In addition, the hinge applies the elastic member of the above scheme.Compared with prior art, the elastic member of the utility model can change the stress curve of spring under different opening and closing angle states by increasing the arc bending part, ensure the weak balance between spring elasticity and door panel gravity, and at the same time, after changing to bending shape, it helps to reduce the angle of spring compression work each time, reduce spring working load.
