Abstract

The utility model relates to a hardware fitting, name are compound spring of stranded, including the spring body, the spring body be that the coil of wire winds and forms, the steel wire be the stranded, the stranded for the steel wire bonding material bond together, bonding material be plastics, plastics form glossy circular structure in the outside of stranded steel wire, the core wire of stranded steel wire in the middle of having is steel wire on every side around the core wire, and core wire's diameter is greater than gauge of wire on every side. Such spring has the reduction to be fallen the emergence of phenomenon absolutely, uses more insurable advantage, bonding material be plastics, plastics form glossy circular structure in the outside of stranded steel wire, have advantages such as the steel wire outside is cleaner and tidier, the core wire of stranded steel wire in the middle of having is steel wire on every side around the core wire, and core wire's diameter is greater than gauge of wire on every side, has the advantage that intensity is higher.

Description

Multiply complex spring

Technical field

This utility model relates to Hardware fitting, particularly relates to spring.

Background technology

Spring be steel wire wound cylindrical structural；In prior art, spring is coiled to form with a reinforcing bar, and such spring has easy drop, adds the risk of use.

Summary of the invention

The purpose of this utility model is aiming at disadvantages mentioned above, it is provided that a kind of reduce drop phenomenon generation, use the spring multiply complex spring more insured.

The technical solution of the utility model is achieved in that: multiply complex spring, and including spring body, described spring body is that steel wire is coiled to form, and it is characterized in that: described steel wire is multiply, and steel wire strand adhesives bonds together.

Saying further, described adhesives is plastics, and plastics form smooth circular configuration in the outside of steel wire strand.

Saying further, described steel wire strand has the core wire of centre, is around steel wire around core wire, and the diameter of core wire is more than surrounding gauge of wire.

The beneficial effects of the utility model are: such spring has the generation of minimizing drop phenomenon, uses the advantage more insured；Described adhesives is plastics, and plastics form smooth circular configuration in the outside of steel wire strand, has the advantage such as cleaner and tidier outside steel wire；Described steel wire strand has the core wire of centre, is around steel wire around core wire, and the diameter of core wire is more than surrounding gauge of wire, has the higher advantage of intensity.

Accompanying drawing explanation

Fig. 1 is vertical section structure schematic diagram of the present utility model.

Fig. 2 is the part B structure for amplifying schematic diagram in Fig. 1.

Wherein: 1, spring body 2, plastics 3, core wire 4, around steel wire.

Detailed description of the invention

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, 2, multiply complex spring, including spring body 1, described spring body is that steel wire is coiled to form, and it is characterized in that: described steel wire is multiply, and steel wire strand adhesives bonds together.

Saying further, described adhesives is plastics 2, and plastics form smooth circular configuration in the outside of steel wire strand.

Saying further, described steel wire strand has the core wire 3 of centre, is around steel wire 4 around core wire, and the diameter of core wire is more than surrounding gauge of wire.

The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and change or the modification made all are contained in the scope of the claims of the present utility model.
