Description
Technical field
The utility model relates to a kind of spring, and more particularly, it relates to a kind of travel switch torsion spring.
Background technology
Current travel switch adopts twisting axle to rotate, and drives pushrod movement, thus drives switch press plate to rotate, and then changes the on off state of wherein sensitive switch.In the torsional pole fixed journey system switch pedestal of one end, other end torsional pole is fixed on switch press plate, and when switch press plate does not also arrive the restriction site in forward or direction, the deformation of torsion spring is little by little increasing, and restoring force also little by little strengthens.But this torsion spring, in deformation energy process, easily banking, after external force is cancelled, torsion spring can not return to initial condition rapidly to torsion spring, affects the flexibility of travel switch, and meanwhile, this torsion spring structure is comparatively large, assembling difficulty.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of compact conformation, the travel switch torsion spring of the flexibility that do not affect travel switch.
For achieving the above object, the utility model provides following technical scheme: a kind of travel switch torsion spring, comprise the torsion spring body with a steel wire wound, torsional pole, described torsion spring body comprises torsion spring body outer ring, torsion spring body inner ring, described torsion spring body inner ring is placed in torsion spring body outer ring, described torsion spring body outer ring, the longitudinal center line of torsion spring body inner ring overlaps, described torsion spring body outer ring, the rotation direction of torsion spring body inner ring is contrary, described torsional pole comprises the first torsional pole, second torsional pole, described first torsional pole is connected with torsion spring body outer ring, second torsional pole is connected with torsion spring body inner ring, described first torsional pole and the second torsional pole are all positioned at torsion spring body outer ring, on the same side of torsion spring body inner ring, described first torsional pole is mutually adjacent to the second torsional pole and intersects and is "X" shape, and the angle that the first torsional pole and the second torsional pole are formed is acute angle.
By adopting technique scheme, torsion spring body outer ring, torsion spring body inner ring can be cancelled out each other the radial load that torsion can produce, make travel switch torsion spring can not be banking, especially compare in the market, that two poles lay respectively at torsion spring circle both sides, and the Double-layer torsion spring diverged to dorsad, the structure of this torsion spring is compacter, required taking up room is less, simultaneously, concentrate stressed, easy to assembly, under the prerequisite not changing material and specification, larger stiffness factor can be provided, long service life, and, torsion spring recovers rapid after elastic deformation, operate more flexible.
The utility model is set to further: described first torsional pole becomes 15 ~ 25 degree to place with the second torsional pole, in guarantee torsion spring performance prerequisite, only need open the first torsional pole and the second torsional pole a little, just can assemble by low-force amount, be convenient to assembling.
The utility model is set to further: torsion spring body outer ring circle more not a half than the number of active coils of torsion spring body inner ring, makes the first torsional pole and the second torsional pole easily be adjacent to, make torsion spring structure more reasonable.
By adopt technique scheme, described torsion spring body inner ring is placed in torsion spring body outer ring, make torsion spring structure compacter, take up room little, be convenient to assembling; Described first torsional pole and the second torsional pole are mutually adjacent to and are crossed as acute angle, can cancel out each other the radial load that torsion can produce in torsion spring body outer ring, torsion spring body inner ring, make travel switch torsion spring banking, can not can not affect the flexibility of travel switch.
Accompanying drawing explanation

Fig. 2 is the left view of a kind of travel switch torsion spring of the utility model.
In figure 1, torsion spring body; 2, torsional pole; 11, torsion spring body outer ring; 12, torsion spring body inner ring; 21, the first torsional pole; 22, the second torsional pole.
Embodiment
Referring to figs. 1 through Fig. 2, a kind of travel switch torsion spring of the utility model is described further.
A kind of travel switch torsion spring, comprise the torsion spring body 1 with a steel wire wound, torsional pole 2, described torsion spring body comprises torsion spring body outer ring 11, torsion spring body inner ring 12, described torsion spring body inner ring 12 is placed in torsion spring body outer ring 11, described torsion spring body outer ring 11, the longitudinal center line of torsion spring body inner ring 12 overlaps, described torsion spring body outer ring 11, the rotation direction of torsion spring body inner ring 12 is contrary, described torsional pole 2 comprises the first torsional pole 21, second torsional pole 22, described first torsional pole 21 is connected with torsion spring body outer ring 11, second torsional pole 22 is connected with torsion spring body inner ring 12, described first torsional pole 21 and the second torsional pole 22 are all positioned at torsion spring body outer ring 11, on the same side of torsion spring body inner ring 12, described first torsional pole 21 is mutually adjacent to the second torsional pole 22 and intersects and is "X" shape, and the angle that the first torsional pole 21 and the second torsional pole 22 are formed is acute angle, torsion spring body outer ring, torsion spring body inner ring can be cancelled out each other the radial load that torsion can produce, make travel switch torsion spring can not be banking.
Described first torsional pole 21 is placed with the second torsional pole 22 one-tenth 15 ~ 25 degree, and this angle is the most suitable, in guarantee torsion spring performance prerequisite, only need open the first torsional pole and the second torsional pole a little, just can assemble by low-force amount, be convenient to assembling; Certainly, also other angle can be placed as.
Described torsion spring body outer ring 11 circle more not a half than the number of active coils of torsion spring body inner ring 12, the first torsional pole and second is twisted and is easily adjacent to, structure is compacter.
