The second U-typed portion is connected with extending part.
Preferably, the joint portion points to the axle center of spring body and parallel to foundation ring, the first U-typed portion opening
Upwards, Open Side Down in the second U-typed portion, and the first U-typed portion is perpendicular to the second U-typed portion.
Preferably, the length of the extending part is twice of spring body free height.
Preferably, the internal diameter of the collar of the spring body is 5mm-10mm.
Beneficial effect：Compared with prior art, the utility model has advantages below：
Oval section volute spring of the present utility model adds an afterbody, volute spring on the basis of plain taper spring
Stability itself is preferable, when bearing pressure, will not double swerve, directly compress vertically downward, in electronic goods or toy
Inner space is smaller, and spring preferably can be fixed and installed by increased afterbody, more convenient during production, improves production effect
Rate, and it is easy to follow-up maintenance.
Brief description of the drawings
Fig. 1 is oval section volute spring structural representation.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, embodiment is with the utility model skill
Implemented under premised on art scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this practicality
New scope.
As shown in figure 1, a kind of oval section volute spring, including spring body 1 and afterbody 2, spring body 1 are helical form taper
Spring, spring body 1 are formed by a spring wire spiral winding, the internal diameter of the collar 3 of spring body 1 and the internal diameter ratio of foundation ring 4
It is worth for 1:7-1：10, afterbody 2 is connected with the end of foundation ring 4, and afterbody 2 is along the axially vertical down-set of spring body 1.
