Abstract
The utility model discloses a kind of double-helix spring, including back-shaped double-helix spring body, described double-helix spring body is by the internal coiling spring of multi-turn, the external spiral spring of multi-turn, vortex-like spring composition under the upper vortex-like spring of multi-turn and multi-turn, described internal coiling spring and external spiral spring are distributed and the most equal with one heart, coupled by upper vortex-like spring between upper starting point and the upper starting point of external spiral spring of described internal coiling spring, between lower terminal and the lower terminal of external spiral spring of described internal coiling spring by under vortex-like spring couple, this utility model simple in construction, manufacture easy to use, cost-effective, so that internal coiling spring and external spiral spring concentric all the time and stress equalization, ensure the performance of spring, improve service life, practical, it is worthy to be popularized.
Description
Technical field:
This utility model relates to spring technical field, a kind of double-helix spring.
Background technology:
Spring is a kind of machine components utilizing elasticity to carry out work, in order to control parts motion, relax impact or vibrations,
Storage or saving energy, the size etc. of measurement power, be widely used in machine, instrument, through conventional two equal height different inner diameters in reality
Spring concentric locking collar use together, but between two springs easily with respect to mobile cause concentric, so that spring is subject to
Unbalanced being easy for of power produces tilt phenomenon, the most not only affects the service behaviour of spring, is more easy to make spring breaking down, reduces spring
Service life.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, concentric all the time and stress
The double-helix spring of equilibrium.
This utility model solves the scheme of described technical problem: a kind of double-helix spring, including back-shaped Double helix bullet
Spring body, described double-helix spring body is by the internal coiling spring of multi-turn, the external spiral spring of multi-turn, the upper vortex-like spring of multi-turn
Vortex-like spring forms with under multi-turn, and described internal coiling spring and external spiral spring are distributed and the most equal with one heart, described interior spiral shell
Coupled by upper vortex-like spring between upper starting point and the upper starting point of external spiral spring of rotation spring, the lower end of described internal coiling spring
Point with the lower terminal of external spiral spring between by under vortex-like spring couple.
The hand of spiral of described internal coiling spring and external spiral spring is contrary.
Prominent effect of the present utility model is: the internal coiling spring being arranged concentrically and external spiral spring are by upper vortex-like spring
Under with, vortex-like spring couples becomes an entirety so that stabilized structure, it is ensured that during use, internal coiling spring and external spiral spring begin
It is in concentric eventually, vortex-like spring under the upper vortex-like spring being respectively multi-turn up and down of double-helix spring and multi-turn, it is ensured that
Spring stress equalizes and firm without tilting, and the hand of spiral of internal coiling spring and external spiral spring is contrary, improves entirety
Rigidity, this utility model simple in construction, manufacture and easy to use, cost-effective, improve the performance and used life of spring, economical
Practicality, has the highest economic and social benefit, is worthy to be popularized.
Accompanying drawing illustrates:
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the perspective view at another visual angle of this utility model.
Detailed description of the invention:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, this utility model provides a kind of technical scheme: a kind of double-helix spring, including back-shaped double
Helical spring body, described double-helix spring body by the internal coiling spring 1 of multi-turn, the external spiral spring 2 of multi-turn, multi-turn upper
Under vortex-like spring 3 and multi-turn, vortex-like spring 4 forms, and described internal coiling spring 1 and external spiral spring 2 are distributed and height phase with one heart
Deng, coupled by upper vortex-like spring 3 between upper starting point and the upper starting point of external spiral spring 2 of described internal coiling spring 1, described interior
Between lower terminal and the lower terminal of external spiral spring 2 of helical spring 1 by under vortex-like spring 4 couple.
The hand of spiral of described internal coiling spring 1 and external spiral spring 2 is contrary.
When in use, the internal coiling spring 1 being arranged concentrically and external spiral spring 2 are by upper vortex-like bullet for this utility model
Spring 3 and under vortex-like spring 4 couple and become an entirety so that stabilized structure, it is ensured that internal coiling spring 1 and external spiral bullet during use
Spring 2 is in concentric all the time, vortex-like spring under the upper vortex-like spring 3 being respectively multi-turn up and down of double-helix spring and multi-turn
4, it is ensured that spring stress equalizes and firm without tilting, and the hand of spiral of internal coiling spring 1 and external spiral spring 2 is contrary, carries
High overall rigidity, this utility model simple in construction, manufacture and easy to use, cost-effective, improve performance and the use of spring
Life-span, economical and practical, there is the highest economic and social benefit, be worthy to be popularized.
Finally, embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant skill
The those of ordinary skill in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Changing and modification, the technical scheme of the most all equivalents falls within category of the present utility model, patent protection model of the present utility model
Enclose and should be defined by the claims.
