Abstract
A kind of Double helix compression spring of the present utility model, including cylindrical spring body, the spring body includes external spiral spring body and the internal coiling spring body being arranged in the external spiral spring body；The external spiral spring body is consistent with the spiral density of the internal coiling spring body and the external spiral spring body body diameter more than the internal coiling spring body body diameter.Double-helix spring body of the present utility model is nested to be arranged, it is ensured that be not susceptible to misplace in compression spring deformation process, it is ensured that deformation is uniform, stable work in work.
Description
Technical field
A kind of a kind of the present invention relates to spring, more particularly to Double helix compression spring.
Background technology
Compression spring is subject to the helical spring to pressure, has certain gap between the circle and circle of compression spring, when receiving
To spring contraction deformation during external applied load, deformation energy is stored, produce reverse expansionary force.But existing cylinder hollow compression spring is deposited
Problem be in compression process, easily occur that deformation is uneven to produce non axial dislocation.
Content of the invention
In order to solve the above problems, the present invention provides a kind of stable performance and is not susceptible to dislocation and the uniform Double helix of deformation
Compression spring.
A kind of Double helix compression spring of the present invention, including cylindrical spring body, the spring body includes external spiral bullet
Spring body and the internal coiling spring body being arranged in the external spiral spring body；The external spiral spring body and the internal coiling bullet
The spiral density of spring body is consistent and the external spiral spring body body diameter more than the internal coiling spring body body diameter.
The double-helix spring body of the present invention is nested to be arranged, it is ensured that be not susceptible to misplace in compression spring deformation process,
Ensure that deformation is uniform, stable work in work.
Description of the drawings
Fig. 1 is the Double helix compression spring structural representation of the present invention；
Fig. 2 is schematic top plan view in Fig. 1.
Specific embodiment
In order to be better understood from the present invention, the present invention is described below in conjunction with the accompanying drawings in detail.
As shown in figure 1, a kind of Double helix compression spring of the present invention, including cylindrical spring body 1, the spring body 1
Including external spiral spring body 2 and the internal coiling spring body 3 being arranged in the external spiral spring body 2；The external spiral spring
Body 2 is consistent with the spiral density of the internal coiling spring body 3；As shown in Fig. 22 body diameter of external spiral spring body is big
Body diameter in the internal coiling spring body 3.
Under optimal way, the diameter of the internal coiling spring body 3 is the 0.6-0.95 of the diameter of the external spiral spring body 2
Times.
The double-helix spring body of the present invention is nested to be arranged, it is ensured that be not susceptible to misplace in compression spring deformation process,
Ensure that deformation is uniform, stable work in work.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, should all be included within the scope of the present invention.
