Abstract
The utility model discloses a hinge torsion spring for a washing machine. The hinge torsion spring comprises a spiral spring body, wherein mounting parts extending outwards are arranged at the two ends of the spiral spring body; the inside diameter of spiral coils at the two end parts of the spiral spring body is larger than that of the spiral coil in the middle. According to the utility model, the shape of the end part of the torsion spring is changed, and the inside diameter of the spiral coils at the end parts of the torsion spring is increased, so that the problem that the hinge torsion spring is fractured during a fatigue test due to the excessively high abrasion between the hinge torsion spring and a hinge shaft can be effectively solved, further, the durability of the hinge torsion spring is improved, and the use quality of the complete machine is guaranteed.
Description
Technical field
The utility model relates to the hinge mounting structure of barrel washing machine door body, specifically a kind of washing machine hinge torsion spring.
Background technology
At present, washing machine hinge torsion spring 1 is through hinge axis 4, and its one end installation portion is assemblied on hinge 2, and other end installation portion is assemblied in (see figure 2) on hinge stiffening plate 3.Hinge 2, hinge stiffening plate 3, hinge torsion spring 1 and hinge axis 4 are by assemblying hinge component.Door of washing machine body is fixed by screws on hinge stiffening plate, and hinge stiffening plate can be rotated around hinge axis, thereby realizes the folding of door of washing machine body.In the process of door body folding, door body drives hinge stiffening plate to rotate around hinge axis, and makes hinge torsion spring produce compression because curling up.In this motion process, the spring body two ends of hinge torsion spring easily contact with hinge axis, produce friction.In fatigue test, tens thousand of times of folding repeatedly of door body, the wearing and tearing of hinge torsion spring and hinge axis are excessive and rupture.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of washing machine hinge torsion spring, change the shape of the two ends torsion spring the most easily contacting with hinge axis at the volley, strengthen its inner end diameter, avoid producing friction with hinge axis, thereby improved the durability of hinge torsion spring.
The technical solution of the utility model is:
Washing machine hinge torsion spring, includes spiral spring body, and the two ends of described spiral spring body are provided with outward extending installation portion, and the spiral coil internal diameter at described spiral spring body both ends is greater than the spiral coil internal diameter at middle part.
The spiral coil at described spiral spring body both ends is the two circle spiral coils that are positioned at spiral spring body both ends and are connected respectively with two installation portions, and the spiral coil internal diameter at described middle part is the spiral coil between two circle spiral coils.
Advantage of the present utility model:
The utility model changes the shape of torsion spring end, strengthens the internal diameter of its end convolution circle, can effectively solve hinge torsion spring in fatigue test because of with excessive fracture of hinge axis wearing and tearing, thereby improve the durability of hinge torsion spring, guarantee the using character of complete machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is mounting structure schematic diagram of the present utility model.
The specific embodiment
See Fig. 1, washing machine hinge torsion spring, includes spiral spring body, and the two ends of spiral spring body are provided with outward extending installation portion 12, and the spiral coil internal diameter at spiral spring body both ends is greater than the spiral coil internal diameter at middle part; Wherein, the spiral coil at spiral spring body both ends is the two circle spiral coils 13 that are positioned at spiral spring body both ends and are connected respectively with two installation portions 12, and the spiral coil internal diameter at middle part is the spiral coil 11 between two circle spiral coils 13.
See Fig. 2, owing to adding the internal diameter of king bolt spring body both ends spiral coil 13, in the process of door body folding, torsion spring 1 end can not produce friction with hinge axis 4, thereby has improved the durability of hinge torsion spring.
Claims (2)
