The solidus end cavity at two ends up and down all forms conical bottom in the solidus end.

The cavity sidewalls of solidus end lower end is provided with through hole.

The utility model is to the further improvement of existing hyperbola line spring, has improved its switching performance and reliability in all its bearings, and is specific as follows:

1) become twisted pair wire from solid wire, connect contact area and increase, contact resistance is reduced, electric property improves, and has also improved anti-seismic performance simultaneously;

2) increased mode of texturing, from original having only radial deformation and around the axle wrench deformation, change into radial deformation, the little distortion of the twisting between axle wrench deformation and twisted pair wire, thereby the life-span of having improved jack has increased its anti-seismic performance;

3) jack is adjustable, thereby has changed the diameter of jack, after contact a period of time, can increase the reliability that connects through adjustment, has also improved being electrically connected property, and in addition, the jack scalable makes the corresponding multiple contact pin of a kind of jack become possibility, has strengthened application;

4) jack diameter scalable has changed the mounting technology of original hyperbola line spring, makes that assembling is simpler, is more conducive to practical application;

5) because little distortion of twisted pair wire is a strain, so increased the self-cleaning function of jack itself.

Description of drawings

To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:

Fig. 1 is the overall structure exploded view of the utility model;

Fig. 2 is the overall structure cutaway view of the utility model;

Fig. 3 is the upward view of the utility model.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Like Fig. 1～shown in Figure 3 is the adjustable torsion spring jack devices of a kind of pair twist hyperbola of the utility model, comprises solidus end 6, and the two ends up and down of solidus end 6 are equipped with cavity.

Wherein, be with down fixed support 4 in the cavity of solidus end 6 upper ends, the lower ends of the upper end of following fixed support 4 and last fixed support 2.

Following fixed support 4 is provided with taper reed 3 with last fixed support 2 connecting places.

Last fixed support 2 exposes with following fixed support 4 and is with enclosing cover 1 on the part outside the solidus end 6.

In addition, the bottom of solidus end 6 upper end cavitys, down fixed support 4, on be provided with twisted-pair feeder 5 in the space that surrounded of fixed support 2 and enclosing cover 1.Wherein, the pitch of twisted-pair feeder 5 is adjusted according to concrete application demand difference and is changed.

$P=\frac{360*(\sqrt{H^2+{(D*\sin (\mathrm{\θ}/2))}^2}-H)}{\mathrm{\θ}}$

Definition P is the pitch of following fixed support 4 with last fixed support 2 last laps; θ is the anglec of rotation (0 °＜θ＜360 °) of twisted-pair feeder 5 around axis; H is the height of twisted-pair feeder 5; D is the diameter of twisted-pair feeder 5.Wherein, the coca of twisted-pair feeder 5 changes according to the variation of the combined altitudes of following fixed support 4 and last fixed support 2.In addition, the internal diameter varies of fixed support 4 under the diameter of twisted-pair feeder 5 basis.
