Background technology

The patent No. is that (notification number: 2391497) disclose the chair that a kind of seat board is incorporated into steel pipe, as shown in Figure 1, this chair includes: a seat board was set as the plate of reservation shape on August 16th, 2000 for the utility model patent of ZL99244421.7; Four bonding pads are arranged at four arms of angle of this seat board bottom, respectively on this bonding pad and have a conjugate foramen; One chair foot rest, be to constitute by two corresponding identical steel pipes, each steel pipe is to have a cross bar and two chair pin, and the chair foot rest that winding is finished has four chair pin can be located on the ground by bracing frame, and tool also is provided with four to conjugate foramen that should four bonding pads and articulates perforation on this two cross bar; Four locating pieces respectively run through being provided with a cross-drilled hole and an axis hole, can involutoryly pile up collection with two steel pipes that this chair foot rest is provided in view of the above, and minimizing institute takes up space and is beneficial to carrying and storage.

The seat board that provides by technique scheme is incorporated into the chair of steel pipe, and complex structure, assembling are loaded down with trivial details, and all attaching parts all are directly exposed to the outside, influence the product integral aesthetic property., must take off connecting four bonding pads of seat board with the chair foot rest during with involutory the piling up of two steel pipes of this chair foot rest at needs, repeated disassembled and assembled like this extremely bothers and easily causes getting loose of bonding pad, influences the safe in utilization of product.

Summary of the invention

The purpose of this utility model is to provide a kind of combined and instant, safe combined type chair attractive in appearance.

The utility model is achieved in that it comprises seat, backrest and framework, and backrest is connected on the framework by the casing pipe sleeve of both sides, and seat engages with framework by the fixture block of bottom.Framework comprises two front support legs, two rear legs, a front-axle beam, a back rest, two curb girders and two back rest supports pipes, front support leg, rear leg, front-axle beam, the back rest, curb girder and back rest supports Guan Jun are hollow pipe fittings, the joint of front support leg and front-axle beam, curb girder is provided with preceding conjugative component, and the joint of rear leg and back rest supports pipe, the back rest and curb girder is provided with the back conjugative component.

Backrest of the present utility model and seat can be fixed on the framework easily, and frame attachment members all is located at inside, and is firm in structure, make product integral body exquisite more attractive in appearance and safe in utilization.
