Abstract
The utility model discloses a spring, include that its characterized in that still includes two that set up at least adjacent by crooked spring body (6) that form a plurality of circle (4) of the strip body (2) spiral the buckle device of block (8) are each other gone up just to circle (4), be provided with on buckle device (8) and hold through -hole (14) that the strip body (2) passed, the strip body (2) with through -hole (14) are clearance fit, and can rotate each other. The utility model discloses can not change spring, not change the elasticity that changes spring under the condition of spring length.
Description
Technical field
The utility model relates to a kind of spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work.There is deformation under external force with the part that elastic material is made, restore to the original state again after removing external force.Also " spring " is made.General spring steel is made.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring, heterotypic spring etc.
F=kx, F are elastic force, and k is [coefficient of, and x is the length of spring elongation, and generally, the length of spring is if fixing, and elastic force is exactly fixing, when needing the elasticity changing spring, need to change spring.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of spring that can regulate elastic force
For solving the problem, the utility model provides a kind of spring, comprise the spring body being formed several circles by strip shape body helical buckling, it is characterized in that, also comprise and being at least arranged on two adjacent described circles and the bayonet unit that can mutually engage, described bayonet unit is provided with the through hole that can hold described strip shape body and pass, described strip shape body and described through hole are Spielpassung, and can rotate each other.
As further improvement of the utility model, described bayonet unit comprises the projection and groove that are separately positioned on its two ends, is provided with the holding space that can hold described projection and snap in described groove.
As further improvement of the utility model, the cross section of described strip shape body and described through hole is circle.
As further improvement of the utility model, described projection is spherical, and the holding space in described groove is the spherical or hemispherical space that diameter is equal with described projection, the surface area of described holding space be greater than described lug surface long-pending 1/2.
As further improvement of the utility model, described circle is equipped with described bayonet unit.
The beneficial effects of the utility model are, the utility model can not change spring, changes the elastic force of spring when not changing its length.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 2-strip shape body; 4-encloses; 6-spring body; 8-bayonet unit; 10-projection; 12-groove; 14-through hole.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises the spring body 6 being formed several circles 4 by strip shape body 2 helical buckling, it is characterized in that, also comprise and being at least arranged on two adjacent described circles 4 and the bayonet unit 8 that can mutually engage, described bayonet unit 8 is provided with the through hole 14 that can hold described strip shape body 2 and pass, described strip shape body 2 is Spielpassung with described through hole 14, and can rotate each other.
As further improvement of the utility model, described bayonet unit 8 comprises the projection 10 and groove 12 that are separately positioned on its two ends, is provided with the holding space that can hold described projection 10 and snap in described groove 12.
As further improvement of the utility model, the cross section of described strip shape body 2 and described through hole 14 is circle.
As further improvement of the utility model, described projection 10 is spherical, and the holding space in described groove 12 is the spherical or hemispherical space that diameter is equal with described projection 10, and the surface area of described holding space is greater than 1/2 of described projection 10 surface area.
As further improvement of the utility model, described circle 4 is equipped with described bayonet unit 8.
Concrete principle of the present utility model is as follows:
(1) when spring does not regulate and directly uses, around spring body 6 rotary buckle device 8, make not to be connected between adjacent bayonet unit 8, now, the elastic force of spring is the initial value of elastic of spring.
(2) when needing the elastic force of Regulation spring, around spring body 6 rotary buckle device 8, the projection 10 making part adjacent snaps onto in groove 12, two now adjacent spring rings 4 cannot move, therefore the spring force of this section is limited, when the spring ring more than 4 of restriction, spring force is less, can regulate voluntarily.
Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
