Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
In the utility model in the case where not making to illustrate on the contrary, the noun of locality such as " upper and lower, left and right " used is usual
Refer to the upper and lower, left and right shown in refer to the attached drawing；" inside and outside " refers to the inside and outside of the profile relative to each component in itself.
One side according to the present utility model, the utility model provide a kind of spring, as depicted in figs. 1 and 2, the bullet
Spring includes spring body 10 and the first connecting portion 20 that is connected with one end of spring body 10, the first connecting portion 20 with
Spring body 10 is angled to be set and forms avoidance opening 30.Preferably, the first connecting portion 20 and spring body 10 can be with
Using arc transition.Wherein, arc transition here can be understood as the situation of no turning point, that is to say, that similar broken line
Transition is not belonging to the situation of arc transition here.
In the utility model, since first connecting portion 20 and spring body 10 use arc transition, it can reduce
The extra-stress of generation when first connecting portion 20 is connect with spring body 10 using other modes, so as to improve the use of spring
Service life.In addition, in the utility model, by spring apply lock or other lock when, as shown in figure 3, in installation process
In, it can be by avoiding opening 30 as first connecting portion 20 and treating that connecting component (such as lock ring 50 in Fig. 3) offer operation is empty
Between, avoiding the setting of opening 30 in this way can interfere or squeeze to avoid the lock ring 50 in installation process and spring body 10
Pressure, so as to improve the installation effectiveness of spring；Meanwhile the setting for avoiding opening avoids spring and occurs to squeeze damage when mounted
It is bad, extend the service life of spring.
Further, the spring includes the second connecting portion 40 that is connected with the other end of spring body 10, and described the
Two connecting portions 40 and the angled setting of spring body 10, and with 10 arc transition of spring body.It is similar as described above, second
The service life that can improve spring similary with the use of spring body 10 arc transition of connecting portion 40 is (because if second connecting portion
40 do not use arc transition with spring body 10 and use broken line transition, at this moment can occur additional answer at the turning point of broken line
Power, so as to influence the service life of spring).Furthermore it is preferred that the first connecting portion 20, spring body 10 and second connecting portion
40 are integrally formed.
Wherein, the second connecting portion 40 is enclosed by elastic material coiling at least one and is formed, the second connecting portion 40
The central axis of center line and spring body 10, so as to be convenient for the installation of spring, as shown in Figure 1.
Further, each circle of the spring body 10 is mutually parallel and diameter is equal, the second connecting portion 40 it is each
Circle is mutually parallel and diameter is equal, and the diameter of any circle of the second connecting portion 40 is less than the straight of any circle of spring body 10
Diameter.Further, the first connecting portion 20 by elastic material coiling at least one enclose and formed, the first connecting portion 20 it is each
Circle is mutually parallel and diameter is equal, and the diameter of any circle of the first connecting portion 20 is less than the straight of any circle of spring body 10
Diameter.The service life of spring can also be further improved in this way, this is because under normal circumstances, the stress point of spring is in spring
At first connecting portion 20 and second connecting portion 40.
In addition, the size for avoiding opening 30 can be by a circle place of the close spring body 10 of first connecting portion 20
The angle a between plane where 10 any circle of plane and spring body determines, as shown in Figure 1, the first connecting portion 20
Close to spring body 10 one circle where 10 any circle of plane and spring body where plane between angle a for 40 ° extremely
50 °, more preferably, it is contemplated that the convenience of installation and the intensity of structure, the close spring body 10 of first connecting portion 20
The angle a between the plane where 10 any circle of plane and spring body where one circle is 44 ° to 50 °.In order to further carry
The structure of multi-turn may be used in the service life of high spring, first connecting portion 20 and second connecting portion 40.Wherein, the specific number of turns
It can be determined according to actual conditions.
Another aspect according to the present utility model, the utility model also provide a kind of lock, as shown in figure 3, the lock
It is connect including installation ontology 70, lock ring 50 and above-mentioned spring, the first connecting portion 20 of the spring with lock ring 50, the spring
