Specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in figure 1, the present invention include becoming columned spring body 4 by strip shape body 2 helical buckling it is characterised in that
Also include：
- adjustable plate 6,, at least provided with two pieces, described adjustable plate 6 is set on described spring body 4 and can be along described bar for it
Circumference slip is done in the partial contour face of shape body 2, and the opposite face of two described adjustable plates 6 is also equipped with described spring body 4 together
The annular groove 8 of axis；
- adjusting rod 10, its at least provided with one and can be axially retractable, the two ends of described adjusting rod 10 respectively spacing in institute
State in annular groove 8 and can be additionally provided with described adjusting rod 10 and can limit it axially along the circumference slip of described annular groove
The fixing device of size.
As a further improvement on the present invention spring it is characterised in that described adjusting rod 10 include two can be axially opposed
Point body of rod 12 sliding, described in two, one end of point body of rod 12 is separately positioned in described annular groove 8.
Spring is it is characterised in that described fixing device is to be fixed on adjacent described point as a further improvement on the present invention
On the body of rod 12 and the clamping device that the described point of body of rod 12 can be clamped.
Spring is it is characterised in that described point of body of rod 12 is provided with the bar-shaped trough 14 of insertion as a further improvement on the present invention,
At least partly connect between adjacent described bar-shaped trough 14.
As a further improvement on the present invention spring it is characterised in that described clamping device include can be in described bar-shaped trough 14
The bolt 16 of interior slip and the nut 18 with the cooperation of described bolt 16 screw thread, described bolt 16 one end is provided with the head radially widened
Portion 20, the radial direction full-size of the those widened sections of described nut 18 and head 20 is more than the width of described bar-shaped trough 14.
The operation principle of the present invention is as follows：
The present invention can be adjusted to the elastic force of spring according to demand：
(1) when the elastic force needing to reduce spring, can be along the contoured surface rotation adjustable plate 6 of spring so that two pieces are adjusted
Spacing between section plate 6 is sufficiently large, then tightens the nut 18 on bolt 16, and two pieces points of bodies of rod 12 of clamping are so that divide between the body of rod 12
Produce larger frictional force, prevent from mutually moving between point body of rod 12, play fixing effect, the bullet now contacting with adjustable plate 6
Spring contoured surface is fixed cannot provide spring force, thus playing the effect reducing spring force.
(2) when the elastic force needing to improve spring, the contoured surface along spring rotates adjustable plate 6, reduces between adjustable plate 6
Spacing, then tightens the nut 18 on bolt 16, clamps two pieces points of bodies of rod 12, and the spring section that now adjustable plate 6 limits is shorter, limit
The elastic force of system is less, and comparatively elastic force is larger.
(3) when the elastic force without limited spring, bolt 16 and nut 18 can be unclamped so that a point body of rod 12 is in freedom
State, now, spring can be with Free Compression.
Above example is only a kind of present invention embodiment therein, and its description is more concrete and detailed, but can not
Therefore it is interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
