Abstract

The utility model discloses a firm tension spring, including spring main part and connector link, still be equipped with the joint portion that is used for cooperating the connector link in the spring main part, be equipped with the network structure who is used for strengthening spring stress in the joint portion. The utility model discloses be equipped with the stress of network structure in order to strengthen spring joint portion between the ring of spring joint portion and ring, effectively prevent that spring joint portion deformation leads to tension spring to scrap when tensile repeatedly, improved the economic benefits and the life of product.

Description

Firm tension spring

Technical Field

The utility model relates to a spring technical field, concretely relates to firm tension spring.

Background

The spring is a mechanical part which works by utilizing elasticity, the tension spring is also a spring which is often used in sports equipment, and when the tension spring works, two ends of the tension spring are connected with a sheet metal part through connecting buckles and then connected with an object to perform stretching movement. After the connecting buckle of the existing tension spring is clamped with the spring, the spring can be deformed by repeatedly stretching the spring, so that the connecting buckle falls out to enable the tension spring to be scrapped.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to solve the problem, the utility model provides a simple structure, firm and long service life's tension spring.

(II) technical scheme

The utility model discloses a firm tension spring, including spring main part and connector link, still be equipped with the joint portion that is used for cooperating the connector link in the spring main part, be equipped with the network structure who is used for strengthening spring stress in the joint portion.

In some embodiments, the spring body includes a first ring and a second ring, and the mesh structure is connected between the first ring and the second ring to reinforce the spring stress so that the spring is not deformed by repeated stretching.

In some embodiments, the connecting buckle comprises a limiting part and a bending part which are used for being matched with the spring clamping part.

(III) advantageous effects

Compared with the prior art, the utility model, it has following beneficial effect: be equipped with network structure with the stress of reinforcing spring joint portion between the ring of spring joint portion and ring, effectively prevent when tensile spring joint portion deformation from leading to tension spring to scrap, improved the economic benefits and the life of product.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic view of a partial connection structure of a spring and a connection buckle according to a preferred embodiment of the present invention.

Fig. 2 is a schematic structural diagram of a preferred embodiment of the mesh structure of the present invention.

1. The spring comprises a spring main body 11, a clamping part 12, a first ring 13 and a second ring;

2. a connecting buckle 21, a limiting part 22 and a bending part;

3. a net structure.

Detailed Description

As shown in fig. 1-2, a firm tension spring comprises a spring main body 1 and a connecting buckle 2, wherein a clamping portion 11 used for matching with the connecting buckle 2 is further arranged on the spring main body 1, and a net-shaped structure 3 used for enhancing the stress of the spring is arranged on the clamping portion 11.

Further, the spring body 1 comprises a first ring 12 and a second ring 13, and the mesh structure 3 is connected between the first ring 12 and the second ring 13 to reinforce the spring stress.

Further, the connecting buckle 2 includes a limiting portion 21 and a bending portion 22 for cooperating with the spring clamping portion 11.

Further, the radius of the joint portion 11 of spring is less than the radius of spring main part 1, and spring main part 1 extends the spring axial and extends the formation to the center gradually promptly, and spacing portion 21 of connector link 2 will be wider than the diameter of joint portion 11, so that connector link 2 can the joint at spring main part 1 internal, through the stress of the network structure 3 of welding between 11 rings of spring joint portion and ring strengthened spring joint portion, so as to prevent that the spring from scrapping because of tensile joint portion deformation messenger spring repeatedly.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
