Abstract
The utility model discloses a kind of sofa serpentine spring hook, the inner piece that the outer suspension member and plastic material being made including metal material are made, the outer suspension member includes fixing end and barb-like extension spring end, the fixing end is provided with multiple fixing holes, the inner piece includes that the liner main body hung in spring end, the hook hole being arranged in the middle part of liner main body can be pushed, and the hook hole inclines gradually downward along fixing end to spring extreme direction is hung.The inner piece that the outer suspension member and plastic material that the utility model is made of metal material are made is made, while with enough tensile strength, there is certain cushioning effect again, the inner piece is directly snapped in outer suspension member, simple structure, assembling are quick, 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 whole hook can bear bigger pulling force, and improve the service life of hook.
Description
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.
Brief description of the drawings
The utility model is further illustrated with implementation method below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of outer suspension member;
Fig. 2 is the structural representation of inner piece;
Fig. 3 is the structural representation of the present embodiment;
Fig. 4 is the top view of Fig. 3.
Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of sofa serpentine spring hook that the present embodiment is provided, including metal material is made
The inner piece 2 that outer suspension member 1 and plastic material are made, the outer suspension member 1 includes fixing end 3 and barb-like extension spring end 4, described solid
, by one piece of iron plate brake forming, the fixing end is provided with multiple fixing holes 5, and the inner piece 2 includes for fixed end 3 and extension spring end 4
The liner main body 6 hung in spring end 4, the hook hole 7 for being arranged on the middle part of liner main body 6 can be pushed, the hook hole 7 is along fixing end
3 incline gradually downward to the direction of spring end 4 is hung.
Used as preferred embodiment, the top of the liner main body 6 is provided with the sheet metal for being available for hanging the top of spring end 4 and inserts
Slot 8, when the push-in of liner main body 6 is hung in spring end 4, the sheet metal on top is just inserted in slot 8, can effectively be prevented
The sheet metal in portion is upturned and deforms.
For ease of fixed and positioned, the both sides of the liner main body 6 are provided with the rib 9 for being close to outer suspension member edge 1, the gear
Side 9 is integrally formed with liner main body 6.In the present embodiment, the inwall in the hook hole 7 is provided with rough lines.
Preferred embodiments of the present utility model are the foregoing is only, as long as realizing the utility model with essentially identical means
