Description

Sofa

Technical field

A kind of furniture is the utility model is related to, more specifically, it relates to a kind of sofa.

Background technology

For sofa as a kind of household goods, it includes seat frame, sets back frame in the side of seat frame, together When be additionally provided with four legs pair and be fixedly connected with seat frame, sponge is then filled with seat frame and back frame Deng filler, sofa is then wrapped to form by cloth, in the prior art in order to increase the service life of sofa and elasticity, S springs and ribbon would generally be installed on seat frame, increase the support force of seat frame by S springs and ribbon, so as to increase Its service life and elastic restoring force.

But in the actual production process, in order to reduce production cost, if seat frame would generally be spelled by dried layer glued board Dress forms, and so when S springs are fixedly mounted, the seat frame both sides parallel with S springs can be subject to the pulling force effect of S springs and easily send out Raw flexural deformation, particularly in use, when human body is acted on S springs, then the tension force of S springs is larger, then is easy to cause glue Plywood cracks and bending, so that the service life of sofa is limited, it is therefore desirable to propose a kind of scheme to solve the technical problem.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of sofa, by glued board Increase supporting part so that the overall structure of glued board gets a promotion, thus will not occur when being subject to S spring pulling force effects cracking or Flexural deformation, ensures the service life of sofa.

To achieve the above object, the utility model provides following technical solution：A kind of sofa, including seat frame, institute If stating seat frame to be made of dried layer plywood knot, the seat frame is laterally installed with some S springs, the seat Frame is vertically installed with some ribbons, and the both sides parallel with S springs are installed with supporting block on the seat frame, props up Bracer, which is located on the inside of seat frame and runs through with seat frame, is fixed with connector.

By using above-mentioned technical proposal, if because seat frame is made of dried layer plywood knot, so cause seat The structural strength of chair frame is substantially reduced relative to than wooden materials, and cost is greatly reduced, therefore in order to improve seat frame Structural strength, supporting block is installed with installation S springs parallel both sides on seat frame, supporting block is fixed on seat by connector On the inside of chair frame, the glued board being so mutually linked can be supported block and fix, play the role of preferably being fixedly connected, at the same time Supporting block can increase the supporting force of seat frame, so that when seat frame is subject to active force flexural deformation, supporting block The bearing capacity of seat frame can be increased, so that seat frame is unlikely to deform, service life increase.

Preferably, the seat frame is also arranged with chair cover, chair cover coats seat frame.

By using above-mentioned technical proposal, seat frame is arranged chair cover, and chair cover at the same time coats seat frame, such side Attractive, decorative is played the role of in face, on the other hand can play a protective role to seat frame.

Preferably, the chair cover is fixedly connected on seat frame by rivet.

By using above-mentioned technical proposal, chair cover is fixed on seat frame by rivet, is so on the one hand to play admittedly Dingan County fills the function of chair cover, on the other hand can also play reinforcement effect to seat frame.

Preferably, rivet reinforcing is also had additional at the position of supporting block on seat frame.

By using above-mentioned technical proposal, rivet, such rivet are also added in the position that supporting block is corresponded on seat frame The connective stability of chair cover can not only be improved, while the connective stability of supporting block can also be increased, so as to preferably increase The bending strength of seat frame.

Preferably, the chair cover has edge, the edge is set in crimping.

By using above-mentioned technical proposal, chair cover is usually that cloth is made, the edge easily scared damage of cloth, therefore The edge of chair cover is sewed after being arranged to crimping, is so allowed for chair cover and is not easy to be damaged, so as to add making for sofa Use the service life.

The utility model tool has the advantage that compared with prior art：Branch is increased by the seat frame synthesized to glued board Bracer, so as to add the bend resistance ability to S springs, avoids seat frame and pulls the situation so that flexural deformation by S springs, prolong The service life of sofa to be stretched, and chair cover is coated in seat frame outer ring, chair cover also sets up rivet in seat frame perimeter and reinforces, So as to further increase the structural strength of seat frame.

Embodiment

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but As long as all protected in the right of the utility model be subject to Patent Law.

Sofa, as depicted in figs. 1 and 2, including seat frame 1, the rectangular frame structure of seat frame 1, and be by The assembled bonding composition of some pieces of glued boards, is installed with the chair back in the upside of seat frame 1, consolidates in the downside of seat frame 1 Dingan County is equipped with four chair legs so as to be made the moulding of sofa, while also some S springs 2 and some knit on seat frame 1 Band 3, the horizontal equidistant arrangement of some S springs 2, the longitudinal equidistant arrangement of some ribbons 3, the both ends of its S spring 2 are fixed on seat frame 1 both sides, the both ends of ribbon 3 are fixed on 1 remaining both sides of seat frame, branch are also installed with the inner side of seat frame 1 Bracer 4, supporting block 4 is located on the seat frame 1 at the both ends of ribbon, and supporting block 4 is made of wood, and supporting block 4 passes through company Fitting 8 is installed on seat frame 1, and connector 8 can use screw, and connector 8 is disposed through supporting block 4 and seat frame Between frame 1, supporting block 4 and seat frame 1 are completely fixed, so when human body is sitting on sofa, S springs 2 can bear compared with Big bearing capacity, makes the seat frame 1 of both sides be drawn close towards centre so as to act on both sides, thus remaining both sides can be subject to compared with Big flecition power, is at this time then supported the seat frame 1 of the both sides by supporting block 4, so that improving it carries energy Power so that Bending Deformation is less likely to occur for the both sides, this makes it possible to the structural strength for increasing seat frame 1 well, so that Improve the service life of sofa.

The flexible materials such as sponge are also filled with seat frame 1 at the same time, are then arranged with chair cover 5 again, chair cover 5 is by cloth It is made, the chair back and seat frame 1 is coated completely, and chair cover 5 is to be fixed on seat frame 1 and chair by rivet 6 Back, chair cover 5 is fixed on the outer ring of seat frame 1 by rivet 6 in the outside of seat frame 1, and also increase has Rivet 6 is used for the connective stability for reinforcing chair cover 5 and seat frame 1, and chair cover 5 is located at the end of 1 edge of seat frame It is in crimping to also set up, and it is in web-like that crimping, which can be set the edge of chair cover 5 by sewing, and the edge 7 of such chair cover 5 is just not easy It is damaged, so as to play more preferable protective effect, ensures the service life of sofa.
