For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of spring not easily broken off relations.
For achieving the above object, the utility model provides following technological scheme: a kind of spring, comprises spring body, drag hook, and described drag hook is provided with the extending portion for anti-locking hook in their extension direction.
As preferably, described drag hook is divided into joint and curved part, and one end of described joint is connected with spring body, and the other end is connected with curved part, described curved part is connected with extending portion, and described curved part and extending portion form annulus and internal radius equals the length of joint.
As preferably, the portion end surface of the free end of described extending portion is in the endoporus of spring body.
As preferably, the distance that the free end of described extending portion arrives spring bores axis is in the horizontal direction 0.2cm.
As preferably, described spring body comprises the first spring body, the second spring body and link arm, and described first spring body is connected with link arm respectively with the second spring body, and the first spring body is parallel with the second spring body.
As preferably, described first spring body and the second spring body are positioned at the same side of link arm.
As preferably, the rotation direction of the first spring body and the second spring body is respectively left-handed and dextrorotation.
As preferably, described drag hook is respectively perpendicular to the first spring body and the second spring body.
As preferably, the shape of the joint of described link arm and spring body is circular arc.
As preferably, described link arm shape is U-shaped, and two ends connect the first spring body and the second spring body respectively.
For achieving the above object, the utility model provides following technological scheme: a kind of spring, comprise spring body, drag hook, spring body comprises the first spring body, second spring body and U-shaped link arm, the two ends of U-shaped link arm connect the first spring body and the second spring body respectively, drag hook is provided with the extension part for anti-locking hook in their extension direction, drag hook is divided into joint and curved part, one end of joint is connected with spring body, the other end is connected with curved part, curved part is connected with extending portion, and shape is identical, the annulus inner ring radius that curved part and extending portion are formed equals the length of joint, because the portion end surface of the free end of extending portion is in the endoporus of spring body, under the condition of rocking, be enclosed within the structure also difficult drop-off on spring, first spring body is parallel with the second spring body, and in the same side of link arm, two spring bodies on average share pulling force, serve structural strength so large, on-deformable effect, the rotation direction of the first spring body and the second spring body is respectively left-handed and dextrorotation, left-right rotary disjunctor, make the balance conformity of this spring better, the shape of the joint of link arm and spring body is circular arc, when being connected with equipment or element, the frayed frictional force of link arm is less, frayed degree is lighter, and long service life.

Fig. 1 is the plan view of the specific embodiment of the utility model spring;
Fig. 2 is the left view of the specific embodiment of the utility model spring;
Fig. 3 is the plan view of the specific embodiment of the utility model spring.
In figure: 1, the first spring body; 2, the second spring body; 3, link arm; 4, curved part; 5, extending portion; 6, free end; 7, joint; 8, drag hook.
Embodiment
Referring to figs. 1 through Fig. 3, the specific embodiment of the utility model spring is described further.
As shown in Figure 1, a kind of spring, comprise spring body, drag hook 8, spring body comprises the first spring body 1, second spring body 2 and link arm 3, first spring body 1 is connected with link arm 3 respectively with the second spring body 2, and the first spring body 1 is parallel with the second spring body 2, under the service condition of long-time high strength, the first spring body 1 and the second spring body 2 can be caused to be out of shape, first spring body 1 be arranged in parallel with the second spring body 2 and makes spring body stressed parallel, avoid the first spring body 1 and the second spring body 2 to be out of shape rear generation to interlock, friction is avoided to cause wearing and tearing to spring body surface, drag hook 8 is divided into joint 7 and curved part 4, one end of joint 7 is welded with spring body, the other end welds with curved part 4, drag hook 8 is provided with the extending portion 5 for anti-locking hook in their extension direction, extending portion 5 welds with curved part 4, the annulus that curved part 4 and extending portion 5 are formed, this internal radius equals the length of joint 7, the portion end surface of the free end 6 of extending portion 5 is in the endoporus of spring body, free end 6 on extending portion 5 is positioned at the endoporus of spring body, when object being hung on drag hook 8, the free end 6 of extending portion 5 has extended in the endoporus of spring body, less gap is there is between free end 6 end points of elongatedness 5 and spring body, when rocking, object can be avoided to break off relations from drag hook 8, free end 6 end points of extending portion 5 is positioned at the top of spring bores axis in the horizontal direction, and the distance to spring bores axis is 0.2cm, the distance of 0.2cm can make extending portion 5 object on drag hook 8 that prevents in a big way break off relations, simultaneously, it also avoid because extending portion 5 is long, cause the object on drag hook 8 hang and take in process more difficult, extending portion 5 free end 6 portion end surface of drag hook 8 has extended in spring bores, ensure that extending portion is enough long, be enclosed within object on drag hook 8 not easily from the edge landing of spring body.
As shown in Figure 1, drag hook 8 is respectively perpendicular to the first spring body 1 and the second spring body 2, first spring body 1 and the second spring body 2 are positioned at the same side of link arm 3, first spring body and the second spring body rotation direction are respectively left-handed and dextrorotation, left-right rotary disjunctor, in the tension masterpiece used time, balance conformity is better, link arm 3 is circular arc with the shape of the joint of spring body, when being connected with equipment or element, when link arm 3 and device contacts, arcuate surface makes link arm 3 friction less, frayed degree is comparatively light, and long service life.
In the present embodiment, the shape of link arm 3 is preferably U-shaped, the two ends of U-shaped link arm 3 are connected with the first spring body 1 and the second spring body 2 respectively, certainly, the shape of link arm 3 also can select W shape or V-arrangement, compared with W shape or V-arrangement, more smooth bottom U-shaped link arm 3, frayed impact is less, and be connected stress surface with device comparatively large, and working life is longer.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
