Abstract
The utility model relates to a torsional spring device comprising a torsional spring and a torsional spring stretching part. The torsional spring stretching part comprises supporting ends embedded in two end portions of the torsional spring in an inserted mode and a supporting rod connected between the two supporting ends in an inserted mode. The length of the torsional spring stretching part is larger than the natural length of the torsional spring. According to the torsional spring device, a certain interval is produced between each circle of the torsional spring, so that friction force can not be produced any more when the torsional spring is twisted and torsional force of the torsional spring can be exerted to the maximum degree. Usage of the tortional spring is more reliable.
Description
Technical field
The utility model relates to a kind of spring, is a kind of torsion spring device specifically.
Background technique
Torsion spring is to produce warping force with the spring of transferring power or motion by torsional elasticity.Each circle of some torsion springs closely centers on, and such torsion spring can produce frictional force between each circle when work, thereby influences the warping force of torsion spring, makes the reliability variation of its work.
The model utility content
The purpose of this utility model just provides a kind of torsion spring device, and in use each encloses the problem that frictional force influences its using effect that produces to solve torsion spring.
The utility model is achieved in that a kind of torsion spring device, comprises torsion spring and torsion spring tensioning member; Described torsion spring tensioning member comprises respectively inserting and is embedded in the support termination at torsion spring two end part and is plugged in two struts that support between the terminations; The length of described torsion spring tensioning member is longer than the natural length of torsion spring.
The set torsion spring tensioning member of the utility model makes torsion spring be in extended state, make and arranged the certain clearance of spring coil generation closely originally, thus, torsion spring is when reversing, just can not produce friction between each spring coil, thereby avoid making because of frictional force the elastic force generation loss of torsion spring.
Described support termination is cylindric, and its external diameter is greater than the internal diameter of described torsion spring.
Have the spliced eye for the grafting strut on the described support termination.
Described support termination comprises the cutting graftage part that is positioned at torsion spring inside and is positioned at the joint of torsion spring outside.
The diameter of described joint is greater than the diameter of described cutting graftage part.
The utility model makes the torsion of torsion spring obtain maximum performance by above setting, makes torsion spring work more reliable.

Fig. 4 supports the structural representation of the another kind of mode of execution in termination for the utility model.
1, strut, 2, torsion spring, 3, support the termination, 31, the cutting graftage part, 32, joint, 33, spliced eye.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further
As shown in Figure 1 and Figure 2, the torsion spring device comprises torsion spring 2 and torsion spring tensioning member.The torsion spring tensioning member comprises respectively inserting and is embedded in the support termination 3 at torsion spring 2 two end part and is plugged in two struts 1 that support between the terminations 3.The length of torsion spring tensioning member is longer than the natural length of torsion spring 2.
Fig. 3 is the structural representation of cylindrical support termination, and supporting termination 3 among Fig. 3 is cylindrical body, and the diameter of cutting graftage part 31 is greater than the internal diameter of torsion spring 2 spring coils, and the diameter of joint 32 is greater than the diameter of cutting graftage part 31.
Fig. 4 supports the cutting graftage part 31 of termination 3 for being positioned at the circle of one on joint 32 end faces hook for supporting the another kind of implementation structural representation of termination among Fig. 4, the number of hook is used for being hooked on and realizes on the spring coil connecting more than or equal to two.Joint 32 can be cylindrical shape or rectangular-shaped.
Above-described embodiment is conceived different implementations on the basis in the present invention in order to explanation but do not limit the utility model, all belongs to protection domain of the present utility model.
