Abstract
The utility model discloses a tension spring, include helicoidal, linking arm, one side of helicoidal is connected with the connection galianconism, passes through the connection of two connection long arms between two helicoidals, and two connection long arms one -tenth V -arrangements are continuous, are connected with the bended -arc section on the connection galianconism, all are provided with symmetrical magnetite in interior every of helicoidal is enclosed, and interior every of helicoidal is enclosed interior symmetrical magnetite and be two or four, the utility model relates to a rationally, simple structure, it is convenient to use, increases the magnetite in every circle in the helicoidal, can prolong tension spring's life, practices thrift the cost.
Description
Technical field
This utility model relates to a kind of extension spring.
Background technology
Extension spring, i.e. stretch spring, also being tension spring, be subject to the helical spring of axial tension, stretching spring the most all uses circular section material to manufacture, when being not subject to load, be typically all and tight very close to each other between the circle of stretching spring and circle, when extension spring uses one section after, the gap between the circle of extension spring and circle can become larger, when gap reaches certain numerical value, extension spring is eliminated.
Utility model content
The purpose of this utility model is to provide a kind of extension spring.
The technical solution adopted in the utility model is:
A kind of extension spring, including bung flange, linking arm, the side of described bung flange connects connection galianconism, long-armed connection is connected by two between said two bung flange, said two connects long-armed forming V-shape and is connected, connect on described connection galianconism and have curved arc section, in each circle in described bung flange, be both provided with the Magnetitum of symmetry.
The symmetrical Magnetitum in each circle in described bung flange is two or four.
Advantage of the present utility model: reasonable in design, simple in construction, easy to use, increase Magnetitum in each circle in bung flange, it is possible to extend the service life of extension spring, cost-effective.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, bung flange；2, curved arc section；3, galianconism is connected；4, connect long-armed；5, Magnetitum.
Detailed description of the invention
As shown in Figure 1, a kind of extension spring, including bung flange 1, linking arm, the side of bung flange 1 connects connection galianconism 3, connecting long-armed 4 by two between two bung flanges 1 to connect, two connect long-armed 4 forming V-shapes and are connected, and connecting to connect on galianconism 3 has curved arc section 2, being both provided with the Magnetitum 5 of symmetry in each circle in bung flange 1, the symmetrical Magnetitum 5 in each circle in bung flange 1 is two or four.
This utility model is reasonable in design, simple in construction, easy to use, increases Magnetitum in each circle in bung flange, it is possible to extend the service life of extension spring, cost-effective.
