Description
Technical field
The present invention relates to stage clip art, refer in particular to the stage clip that a kind of elastic stiffness is adjustable.
Background technique
Stage clip (Compression Spring) is the helical spring bearing axial pressure, because can pressure be born, two ends can be open type or enclosed or around flat or polish, its material section used mostly is circular, also useful rectangle and multiply steel are entangled and are rolled, spring has equal pitch and pitches, the shape of Compress Spring has: cylindrical, conical, the variant of camber and middle concave and a small amount of non-circular and even various tail end, all can design shaping etc. according to product needed, certain gap is had between the circle of stage clip and circle, the spring contraction distortion when being subject to external load, store energy of deformation.
Stage clip is the one be widely used most in all spring kinds, product application range wide and electronics, motor, computer, information, locomotive, bicycle, hardware & tools, furniture, gift, toy and even national defense industry, because its design is easy to grasp with principle, production control is also simple.But current stage clip under normal circumstances length immobilizes not adjustable, thus the length that can not adjust stage clip is according to actual needs to change the rigidity of stage clip, makes troubles to use.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide the adjustable stage clip of a kind of elastic stiffness, and its constant not adjustable of active length that effectively can solve existing stage clip is to using the problem of making troubles.
For achieving the above object, the present invention adopts following technological scheme:
The stage clip that elastic stiffness is adjustable, includes helical compression spring body and integral type spring closing box; This integral type spring closing box has the containing space that can rotate for the helical compression spring body of folding and receive, the upper-end surface of this integral type spring closing box is provided with the through hole being communicated with aforementioned containing space, the material section size of the size and shape of this through hole and the central diameter of helical compression spring body and helical compression spring body matches, and this through hole to the distance of the rotating center of helical compression spring body equals the half of helical compression spring body central diameter; The lower end of this helical compression spring body to be stretched into aforementioned containing space from aforementioned through-hole and is butted on the inner bottom surface of containing space, and rotate relative to integral type spring closing box with helical compression spring body, the compression of this helical compression spring body enters containing space or discharges outside containing space.
As a kind of preferred version, described integral type spring closing box interior shape is rounded.
As a kind of preferred version, described integral type spring closing box is a single piece.
As a kind of preferred version, described integral type spring closing box is an assembly parts.
As a kind of preferred version receive and release helical compression spring body time the lower end of helical compression spring body and the inner bottom surface relative sliding of containing space.
As a kind of preferred version lower end of helical compression spring body and inner bottom surface not relative sliding of containing space when pressurized.
The present invention compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
To stretch into the containing space of integral type spring closing box from through hole by utilizing the lower end of helical compression spring body and be butted on the inner bottom surface of containing space, rotate relative to integral type spring closing box with helical compression spring body, the compression of this helical compression spring body enters containing space or discharges outside containing space, can adjust the active length of helical compression spring body with this, the stage clip active length that instead of tradition immobilizes nonadjustable mode, thus according to the rigidity needing change helical compression spring body of actual conditions, very large convenience can be brought to use.
For more clearly setting forth structure characteristic of the present invention and effect, below in conjunction with accompanying drawing and specific embodiment, the present invention is described in detail.

Embodiment
Please refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of the present invention, include helical compression spring body 10 and integral type spring closing box 20.
This integral type spring closing box 20 interior shape is rounded, this integral type spring closing box 20 has can the containing space 201 of voltage supply superimposition storage helical compression spring body 10, this containing space 201 is rounded, the upper-end surface of this integral type spring closing box 20 is provided with the through hole 202 being communicated with aforementioned containing space 201, this through hole 202 is curved, the radian of this through hole 202 is equal with the radian of helical compression spring body 10, the width of this through hole 202 and the sectional dimension of helical compression spring body 10 suitable, the distance of the rotating center of this through hole 202 to helical compression spring body 10 equals the half of helical compression spring body 10 central diameter, keep original radian indeformable to make helical compression spring body 10.
The lower end of this helical compression spring body 10 to be stretched into aforementioned containing space 201 from aforementioned through-hole 202 and is butted on the inner bottom surface of containing space 201, rotate relative to integral type spring closing box 20 with helical compression spring body 10, the compression of this helical compression spring body 10 enters containing space 201 or discharges outside containing space 201.
The using method that the present embodiment is described in detail in detail is as follows:
Helical compression spring body 10 bottom through the through hole 202 on integral type spring closing box 20, and be screwed into the inner bottom surface of the containing space 201 of integral type spring closing box 20, make the lower end of helical compression spring body 10 press on the inner bottom surface of containing space 201, this is original state; When continuation is equidirectional for helical compression spring body 10 screw-in, the part screwed in will be compressed round and round (determining screw-in amount as required) in containing space 201, and the inner bottom surface generation relative sliding of the lower end of helical compression spring body 10 and containing space 201, at this moment screw-in moment is removed, by the restriction of small space in integral type spring closing box 20, can't be ejected in containing space 201 by the helical compression spring body 10 compressed.This assemblying body is used as a stage clip, and because helical compression spring body 10 active length changes, elastic stiffness changes thereupon.
Design focal point of the present invention is: to stretch into the containing space of integral type spring closing box from through hole by utilizing the lower end of helical compression spring body and be butted on the inner bottom surface of containing space, rotate relative to integral type spring closing box with helical compression spring body, the compression of this helical compression spring body enters containing space or discharges outside containing space, can adjust the active length of helical compression spring body with this, the stage clip active length that instead of tradition immobilizes nonadjustable mode, thus according to the rigidity needing change helical compression spring body of actual conditions, very large convenience can be brought to use.
The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
