Description

A kind of sofa snak link

Technical field

The utility model relates to sofa field, is specifically related to a kind of sofa snak link.

Background technology

Improving constantly in recent years along with people's living standard, sofa has not been any live on the fat of the land product, it spreads to huge numbers of families gradually, but cushion and the back cushion of Most current sofa are made by polyester form, although manufacturing cost is lower, but people sits superincumbent sensation compared with spring pad, and not only gas permeability is bad, and comfort level is obviously not good yet.Therefore, spring pad, due to the perfect adaptation of its flexibility and supportive, uses also not yielding for a long time, has become the first-selection of user.

Spring pad in process of production, both ends of the spring wherein hangs on snak link, snak link is fixed on spring pad framework again, the snak link adopted in industry is now integrated plastic material or metal material two kinds, snak link insufficient strength when Long-Time Service of plastic material, particularly spring pad is when the people that long-time bearing body weight is heavier, use as exported American-European countries, during the heavier westerner of sitting body weight, the extension spring place of snak link is easily damaged, thus cause caving in of spring, cause scrapping of sofa, cause unnecessary waste; For solving the problem, in industry, just there is the snak link of metal material, but the snak link of metal material not only damping property is bad, and Long-Time Service can serious wear to the hook of spring, and even damage, therefore, the actual effect used neither be fine.

Thus, have developed the snak link in conjunction with metal and plastics two kinds of materials at present on the market, but the outer suspension member of metal material is by bending and molding, limit, upper strata and the lower floor limit of its stiff end directly fit together, there is no extra fixing means, cause in use, after stressed, easily loosen, and then cause the rivet fixed or air nail to lose efficacy.

Therefore, improve this snak link, rivet or air nail being fixed reliable, is this area technical issues that need to address.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of sofa snak link, adding the fixed form on limit, upper strata and lower floor limit, ensure that rivet or air nail are fixed reliable.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of sofa snak link, is made up of the outer suspension member of metal material and the inner piece of plastic material; Described outer suspension member comprises stiff end and square tubular hangs spring end, described stiff end has at least two fixing holes, and described stiff end inner side edge is connected with described extension spring end side surface; Described inner piece is also square tubular structure, and its profile is consistent with described extension spring end cavity shape, and described inner piece is closely buckled in described extension spring end; Described stiff end comprises the limit, upper strata and lower floor limit that are superimposed together, and limit, described upper strata is provided with the butt strip with described lower floor limit riveted, and described lower floor limit is provided with the groove coordinated with the butt strip on limit, described upper strata.

Preferably, the both sides of described butt strip are respectively provided with a U-lag.

Preferably, described inner piece two sides are equipped with wedge shape hangnail hook, and are provided with two projections at the lower edges place that described hangnail hook extends rearward to inner piece.

Preferably, described extension spring end two sides have bayonet socket, and described inner piece push be installed to hang in spring end time, described hangnail hook is buckled in described bayonet socket, and described convex barrier is in described extension spring end outer side edges.

Preferably, described fixing hole is four.

Pass through technique scheme, sofa snak link of the present utility model is provided with the butt strip with described lower floor limit riveted on the limit, upper strata of stiff end, described lower floor limit is provided with the groove coordinated with the butt strip on limit, described upper strata, riveted together two-layer up and down by butt strip like this, thus reach and make rivet or air nail fix reliable object.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment.

As Figure 1-5, a kind of sofa snak link, is made up of the outer suspension member 1 of metal material and the inner piece 2 of plastic material; Outer suspension member comprises stiff end 11 and square tubular hangs spring end 12, stiff end has at least two fixing holes 110, and stiff end 11 inner side edge is connected with extension spring end 12 side; Inner piece 2 is also square tubular structure, and its profile is consistent with extension spring end cavity shape, and inner piece 2 is closely buckled in be hung in spring end 12; Stiff end 11 comprises the limit, upper strata 3 and lower floor limit 4 that are superimposed together, and limit, upper strata 3 is provided with the butt strip 31 with lower floor's limit 4 riveted, and lower floor limit 4 is provided with the groove 41 coordinated with the butt strip on limit, upper strata 3.

Wherein, inner piece 2 two sides are equipped with wedge shape hangnail hook 21, and are provided with two projections 22 at the lower edges place that hangnail hook 21 extends rearward to inner piece 2; Hang spring end 12 two sides and have bayonet socket 121, and inner piece 2 push be installed to hang in spring end 12 time, hangnail hook 21 is buckled in bayonet socket 121, protruding 22 are blocked in extension spring end 12 outer side edges, like this, when by inner piece 2 driven forward, just be positioned at the projection 22 of hanging outside spring end 12 on inner piece 2 edge to stop, cannot move forward, and when inner piece 2 is promoted backward, the hangnail hook 21 be buckled in again in bayonet socket 121 stops, cannot retreat, thus inner piece 2 is fixed in the extension spring end 12 of outer suspension member 1.

Wherein, the both sides of butt strip 31 are respectively provided with a U-lag 32.The easier riveted of such butt strip.

Wherein, fixing hole 110 is four.Fixing so more firm.

In the above-described embodiments, sofa snak link of the present utility model is provided with the butt strip with described lower floor limit riveted on the limit, upper strata of stiff end, described lower floor limit is provided with the groove coordinated with the butt strip on limit, described upper strata, riveted together two-layer up and down by butt strip like this, thus reach and make rivet or air nail fix reliable object.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
