Description

A kind of sofa serpentine spring hook

Technical field

The utility model is related to a kind of sofa accessory, and in particular to a kind of sofa serpentine spring applied on sofa is hooked Button.

Background technology

Recently as the continuous improvement of people's living standard, sofa has not been any live on the fat of the land product, and it is gradually popularized Cushion and back cushion to huge numbers of families, but Most current sofa are made by polyester form, although manufacturing cost compared with It is low, but the sensation that people sits on, compared with spring pad, not only gas permeability is bad, and also comfort level is also evidently poor.Therefore, Spring pad, for a long time using deformation is not easy to, has become the first-selection of user due to the perfect adaptation of its flexibility and supportive. In process of production, serpentine spring two ends therein hang on snak link spring pad, and spring hook is fixed on spring pad again On framework, the spring hook for being used in industry now is two kinds of integrally formed plastic material or metal material, plastic material Snak link in long-term use insufficient strength, particularly spring pad export American-European in the people of long-time bearing heavier-weight, such as Country uses, and during the westerner of sitting heavier-weight, is easily damaged at the extension spring of snak link, so as to cause collapsing for spring Collapse, cause scrapping for sofa, cause unnecessary waste；To solve the above problems, the bullet of metal material is just occurred in that in industry Spring hook, but the spring hook of metal material not only damping property is bad, and long-term use to the hook of spring can serious wear, Even damage, therefore, it is also slightly inadequate during practical application.

Thus, a kind of spring hook being combined by metal material and plastic material is also occurred in that on the market, and its structure is such as Shown in the Chinese utility model patent of Patent No. 201520627548.9, although the structure solves the problems, such as intensity and damping, But complex structure, production cost is high, it is unfavorable for large-scale promotion.

The content of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple structure, intensity the snakelike bullet of sofa high Spring hook.

The utility model solves the technical scheme that its technical problem used：

A kind of sofa serpentine spring hook, including the inner piece that the outer suspension member that is made of metal material and plastic material are made, The outer suspension member includes fixing end and barb-like extension spring end, and the fixing end is provided with multiple fixing holes, the inner piece bag Including can push the liner main body hung in spring end, the hook hole being arranged in the middle part of liner main body, the hook hole along fixing end extremely Spring extreme direction is hung to incline gradually downward.

In the utility model, be provided with the top of the liner main body be available for hang spring end top sheet metal insertion insert Groove.

In the utility model, the both sides of the liner main body are provided with the rib for being close to outer suspension member edge.

In the utility model, the inwall in the hook hole is provided with rough lines.

The beneficial effects of the utility model are：Outer suspension member and plastic material system that the utility model is made of metal material Into inner piece be made, while with enough tensile strength, and with certain cushioning effect, the inner piece is directly snapped in In outer suspension member, simple structure, assembling are quick, and further, the hook hole inclines gradually downward along fixing end to spring extreme direction is hung, So that the pulling force effect that outer suspension member is subject to hangs the bottom at spring end, reduce the torque hung between spring end and fixing end, not only entirely Hook can bear bigger pulling force, and improve the service life of hook.
