Abstract

The utility model relates to a spring, in particular to a novel spring with bent hooks. The novel spring comprises hooks at the two ends and an elastic part in the middle. The hook at one end at least is provided with a transverse extension part. The transverse extension part can effectively fix the spring, the hook of the spring does not slip out of a fixing hole, the structure is simple, the manufacturing cost is low and the spring can be used for kinds of places.

Description

A kind of novel bending hook spring

Technical field

The utility model relates to a kind of spring, more particularly, relates to a kind of novel bending hook spring.

Background technique

At present, trampoline is as a kind of sport and body-building apparatus of popularizing day by day, more and more be subjected to liking of Consumer, the general structure of existing trampoline is made up of trampoline face, trampoline frame and the foot rest that is fixed in trampoline frame lower end, the trampoline face is connected with the trampoline frame by spring, and the quality of spring structure directly affects the stability and the Security of trampoline.

As shown in Figure 1, existing spring comprises spring section 1, spring section 1 two ends are provided with " C " shape drag hook 2, little three square rings in the outside of the trampoline face drag hook 2 of packing into, the trampoline frame external frame on be processed with fixed hole, " C " shape drag hook 2 of the other end inserts in the fixed hole, but trampoline is in use, the spring stretching, extension that is stretched, and " C " shape drag hook 2 skids off from fixed hole easily, if collapsible trampoline, " C " shape drag hook 2 of trampoline spring when folding also skids off from fixed hole easily.

The model utility content

The utility model has overcome shortcoming of the prior art, and a kind of novel bending hook spring is provided, and it can prevent effectively that drag hook from skidding off from fixed hole.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of novel bending hook spring comprises the drag hook at two ends and the spring section of centre, and the drag hook of at least one end has horizontal extension part.

Further, an end drag hook has horizontal extension part, and the other end drag hook has the extension part to the longitudinal medial bending.

Further, the described drag hook that has to the extension part of longitudinal medial bending is " 9 " font structure.

Compared with prior art, the beneficial effects of the utility model are:

Horizontal expansion of the present utility model portion can carry out effectively fixing to spring, and the drag hook of spring can not skid off from fixed hole, and it is simple in structure, and low cost of manufacture can be used for multiple occasion.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the three-dimensional structure diagram of existing spring;

Fig. 2 is a three-dimensional structure diagram of the present utility model;

Fig. 3 is a scheme of installation one of the present utility model;

Fig. 4 is a scheme of installation two of the present utility model.

Embodiment

As shown in Figure 2, novel bending hook spring described in the utility model, the spring section 1 in the middle of comprising and the drag hook at two ends, the drag hook 21 of one end has horizontal extension part 211, the other end drag hook 22 has the extension part 221 to the longitudinal medial bending, is " 9 " font structure, and is fixing more firm.

Shown in Fig. 3,4, little three square rings 31 in trampoline face 3 outsides drag hook 22 of packing into, be processed with fixed hole 41 on the external frame 4 of trampoline frame, the terminal secured in alignment hole 41 of the extension part 211 that the other end drag hook 21 is horizontal, insert fixed hole 41, horizontal extension part 211 is promptly fixed drag hook 21, makes it be not easy to skid off from fixed hole 41.

The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
