The spring body offers through-hole on every circle bung flange, and each through-hole is respectively positioned on same straight line, institute
Straight line parallel is stated in the axis of spring body, the straight pin, which prolongs, axially sequentially passes through each through-hole.
In an alternative embodiment, the through-hole is evenly arranged on every circle bung flange, often encloses the number of the through-hole on bung flange
Amount is two.
In an alternative embodiment, the spring body is made of oil hardening steel spiral.
In an alternative embodiment, the surface of the spring body is coated with antirust paint.
In an alternative embodiment, the surface of the spring body is provided with wearing layer.
The beneficial effects of the utility model are：A kind of torsion spring is provided, the often circle bung flange in spring body is passed through
Upper surface opens up boss, opens up groove compatible with boss in the lower surface of the often circle bung flange of spring body, and in spring master
Body often enclose bung flange on corresponding position open up through-hole, enable straight pin sequentially pass through each through-hole, avoid spring stretch and
Twist deviation in compression process, reduces the performance of machine.The utility model is simple in structure, is easily achieved, and improves spring
Torsional property.
Description of the drawings

2- straight pins.
Specific implementation mode
For technology contents, the objects and the effects of the utility model are described in detail, below in conjunction with embodiment and match
Attached drawing is closed to be explained.
The design of the utility model most critical is：Boss is opened up in the upper surface of the often circle bung flange of spring body, in bullet
The lower surface of the often circle bung flange of spring main body opens up groove compatible with boss.
It please refers to shown in Fig. 1 to Fig. 2, a kind of torsion spring of the utility model, including spring body and straight pin；
The spring body is equipped with spiral shape boss in the upper surface along spring rotating path, and the spring body exists
It is equipped with spiral groove compatible with the spiral shape boss along the lower face of spring rotating path, the spiral shape is convex
The cross sectional shape of platform is trapezoidal；
The spring body offers through-hole on every circle bung flange, and each through-hole is respectively positioned on same straight line, institute
Straight line parallel is stated in the axis of spring body, the straight pin, which prolongs, axially sequentially passes through each through-hole.
As can be seen from the above description, the beneficial effects of the utility model are：In the upper surface for often enclosing bung flange of spring body
Boss is opened up, opens up groove compatible with boss in the lower surface of the often circle bung flange of spring body, and in the every of spring body
Corresponding position on circle bung flange opens up through-hole, and straight pin is enabled to sequentially pass through each through-hole.In use, when spring body is oppressed
When, spiral shape boss is embedded in spiral groove, it is therefore prevented that spring radial deflection misplaces；When spring body is stretched, cylinder
Pin can prevent spring body from twisting.
Further, the through-hole is evenly arranged on every circle bung flange, and the quantity of the through-hole often enclosed on bung flange is two
It is a.
As can be seen from the above description, the stability that ensure that spring body structure is designed in this way.
Further, the spring body is made of oil hardening steel spiral.
As can be seen from the above description, spring body is made of oil hardening steel, and intensity is high, good toughness.
Further, the surface of the spring body is coated with antirust paint.
As can be seen from the above description, antirust paint can prevent the surface oxidisation of spring body, extend the service life of spring.
Further, the surface of the spring body is provided with wearing layer.
As can be seen from the above description, wearing layer further extends the service life of spring.
