Brief description of the drawings

Fig. 1 is the preferred embodiment structural representation of the utility model olive shape spring.

Fig. 2 is Fig. 1 another visual angle figure.

Embodiment

To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings The utility model is further described example.It should be appreciated that specific embodiment described herein is only to explain this reality With new, it is not used to limit the utility model.

Please refer to Fig. 1 and Fig. 2, as shown in Figure 1, 2, olive shape spring described in the utility model includes spring body 1, divided Be not arranged on the end lead-out wire 2 at the spring body two ends and be arranged on the tail end of end lead-out wire 2 buckle 3, the bullet Spring main body 1 is in olive shape.General spring body is set to the cylinder of standard, when stress extends outward, two partial deformation It is larger, and center section deformation is smaller, when in actual applications, two part of spring body is easily elastically-deformable beyond its Scope reaches certain distance of stretch out and draw back, and now often there be certain elastic space, this reality in the center section of spring body With the new olive shape structure by the way that spring body 1 to be set to be small at both ends and big in the middle, each portion of spring body 1 is balanced well Divide deformation difficulty so that spring is when stretching, and spring body 1 can be stretched uniformly, and stress is more uniformly distributed, so that Extend the service life of spring.

It is preferred that the pars intermedia of the spring body 1 is in cylinder, it is straight that the pars intermedia of spring body 1, which for example can be set, Footpath 8mm cylindrical structural, the both ends of the spring body 1 are in cone, more preferably, the two ends of the spring body 1 Portion is in a diameter of 6mm in smaller bottom surface conical structure.

It is preferred that the angle of the inclined-plane of the conical end and spring body central axis is 45 °, now spring stress It is more uniform during stretching.

It is preferred that the inclined-plane length of the conical end is identical with the length of cylindrical midsection, and more preferably, the spring The overall length of main body 1 is 12.9mm.

It is preferred that described end lead-out wire 2 is outwards drawn by the ring of spring body 1 and is buckled 3 with described and be connected.More preferably Ground, described end lead-out wire 2 includes the first line department 21 and the second line department 22, ring of first line department 21 from conical end Enclose ring diameter of the edge along conical end to bend to the ring center of conical end, the second line department 22 is by cone The ring of end is bent outward centrally along axis, and the angle of the line department 22 of the first line department 21 and second formation is 90 degree, So cause spring in stretching, the stress point and stress straight line of stretching are along spring center axially direction, it is ensured that In stretching, the assembling point dislocation at two ends can still be located at central shaft center, and uniform force when spring elongation is not susceptible to Deformation.

It is preferred that the length of the end lead-out wire 2 of the spring body 1 wherein one end is more than the end lead-out wire 2 of the other end Length, the length of the end lead-out wire 2 of the other end is identical with the length of spring body 1.

Buckle 3 it is preferred that described and be bent to form by the tail end of end lead-out wire, it is described buckle it is integrated with end lead-out wire 2 Structure so that the olive shape spring is overall more solid, firm.

Buckle 3 it is preferred that described and buckled for triangle, including the third fold line portion connected with the tail end of end lead-out wire 2 31st, the fourth fold line portion 32 connected with the third fold line portion 31, the fourth fold line portion 32 abuts against the end lead-out wire 2 On, more preferably, the fourth fold line portion 32, which is additionally provided with one, to be used to open the extension 33 that the triangle is buckled.

It is preferred that the drift angle that the triangle is buckled（Angle i.e. between the line department 21 of third fold line portion 31 and second）For 35 ° ~ 45 °, more preferably, the drift angle of the triangular hook is 40 °, the third fold line portion 31 and the fourth fold line portion 32 Angle is 71 °, and the fourth fold line portion 32 and the angle of end lead-out wire 2 are 69 °.

In summary, the olive shape spring that the utility model is provided, by the way that spring body is set into olive shape, and end is drawn Outlet is bent to ring center again along axis outward bending from the loop edge of olive shape end along ring diameter, solves existing skill Spring body can not be stretched uniformly in art, easily occur non-reversible deformation, cause spring service life to shorten, and online Using easily causing pulling-on piece problem on deformation in electric field.

It should be appreciated that application of the present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model The protection domain that profit is required.
