Description
Technical field
It the utility model is related to parts technical field, and in particular to a kind of hollow spring.
Background technology
Spring is a kind of elastic component of retractable, is usually used in damping, clamping, energy storage and fields of measurement, with us
Production and living it is closely bound up.Such as mattress, sofa, cushion and the soft substantial amounts of spring of protecting wall needs are made, by
It is metal product in spring, there are own wt, increases product weight when largely using, properties of product is influenced, more without method
Play the performance of spring resilient flexible.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned deficiency of the prior art, there is provided a kind of hollow spring, it is light-weight and
And it is more than the radius of spin of middle ware with elasticity well, the spring body both ends radius of spin, spring has soft elasticity.
The purpose of this utility model is achieved through the following technical solutions：
A kind of hollow spring, including spring body, in the shape of a spiral, spring body runs through along the hand of spiral to be equipped with spring body
Cavity, the spring body include central part and are arranged at the end at central part both ends, and the radius of spin of spring body is by end
Tapered into central part.
Wherein, the radical length of the central part and the radical length of end ratio are 1:4-1:6.
Wherein, the cavity includes center cavity and cavity, and cavity is arranged at the both ends of center cavity, and center cavity is penetrated through with cavity
Connection, the internal diameter of the center cavity are less than the internal diameter of cavity.
Wherein, adapter cavity is additionally provided between the center cavity and cavity, between the side wall of adapter cavity and the side wall of center cavity
Angle be 130 ° -145 °.
Wherein, it is arranged with protective case outside the spring body.
Wherein, the spring body is additionally provided with secondary spring, and the end of the both ends of secondary spring respectively with spring body connects
Connect.
Wherein, the end, which is additionally provided with, supports circle.
The beneficial effects of the utility model：A kind of hollow spring of the utility model, it is light-weight and there is good bullet
Property, the spring body both ends radius of spin is more than the middle radius of spin, elasticity of the spring with softness.
Brief description of the drawings
Utility model is described further using attached drawing, but the embodiment in attached drawing does not form and the utility model is appointed
What is limited, without creative efforts, can also be according to the following drawings for those of ordinary skill in the art
Obtain other attached drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the cut-away section structure diagram of the utility model.
Fig. 3 is another structure diagram of the utility model.
Reference numeral includes：Spring body 1, cavity 2, central part 3, end 4, center cavity 5, cavity 6, adapter cavity 7, protection
Set 8, secondary spring 9, support circle 10.
Embodiment
The utility model is further described with the following Examples.
As depicted in figs. 1 and 2, a kind of hollow spring of the utility model, including spring body 1, spring body 1 is helically
Shape, spring body 1 include central part 3 and are arranged at 3 liang of central part along the hand of spiral through cavity 2, the spring body 1 is equipped with
The end 4 at end, the radius of spin of spring body 1 are tapered into from end 4 to central part 3.A kind of hollow projectile cartridge of the utility model
Spring, light-weight and be more than the middle radius of spin with elasticity well, the 1 both ends radius of spin of spring body, spring has
Soft elasticity.
As depicted in figs. 1 and 2, the radical length of the central part 3 of the utility model and the radical length ratio of end 4 are 1:4-
1:6.By setting different radical lengths than making hollow spring that there is different elasticity, it is preferable that the radical length of central part 3
Radical length ratio with end 4 is 2:3.
As depicted in figs. 1 and 2, the cavity 2 of the utility model includes center cavity 5 and cavity 6, and cavity 6 is arranged at center cavity 5
Both ends, center cavity 5 and 6 through connection of cavity, the internal diameter of the center cavity 5 is less than the internal diameter of cavity 6.It is less by setting
Center cavity 5 enables hollow spring to bear the support force of bigger at center, while 2 spring of cavity is had a resilient flexible both
With certain support force, elastic connecting sense of touch is more preferable.
As depicted in figs. 1 and 2, adapter cavity 7 is additionally provided between the center cavity 5 and cavity 6 of the utility model, adapter cavity 7
Angle between the side wall of side wall and center cavity 5 is 130 ° -145 °.
As depicted in figs. 1 and 2, it is arranged with protective case 8 outside the spring body 1 of the utility model.Protective case 8 can protect sky
The abrasion of heart spring, at the same while being placed with metal product can prevent surface from scratching.
As shown in figure 3, the spring body 1 of the utility model is additionally provided with secondary spring 9, the both ends of secondary spring 9 respectively with
The end 4 of spring body 1 connects, and the elasticity modulus of spring body 1 is more than the elasticity modulus of secondary spring 9.Secondary spring 9 can
Avoid the elastic deformation excessive caused by release suddenly after bearing huge pressure of hollow spring.
As shown in figure 3, the end 4 of the utility model is additionally provided with and supports circle 10, it is larger to support the area of circle 10, can bear
The pressure of bigger.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
