Abstract

The utility model provides a blow molding chair, which consists of a chair support frame, a seat pad and a backrest. The seat pad and the backrest are the hollow components made by injection molding. Both sides of the seat pad are sleeved by a U-shaped frame; the gravity section of the bottom is arranged with a support component as a crossing positioning frame; the turning sections extending from both sides of the support component correspondingly lean against the position with the proper height on the front horse of the chair frame and is positioned by a rivet fixed element; the U-shaped frame on both sides of the seat pad of the device is close the rear end and leans against the position with the proper height on the back horse of the chair frame correspondingly and is positioned by a rivet fixed element; a positioning rod section extends downward from the position of both sides of the backrest near the top part, the positioning rod section is properly embedded in the corresponding pipe diameter of the front horse of the chair frame; a propping section extends from the bottom side of the backrest corresponding to the front horse to keep the backrest stable and position the backrest. Therefore, the utility model achieves the effects of light and convenient integrity, enough strength to bear the outer force, and more convenient carrying for ordinary people after the utility model is folded.

Description

A kind of Blow molding chair

The utility model relates to a kind of commodity folding chair tool, refers to a kind of Blow molding chair especially.

[background technology]

Distinguish very variously with the folding chair tool both deposited on the market forming form and purposes classification, and each type is formed chair tool and is all respectively had its unique locating of differing in the use; A kind of known folding seat, its seat cushion bottom is provided with a circle metal system fixture, the chair tool supporting frame of forming with metal tube combines, can support and mount the back for using, can deposit after folding the folding with not taking too much space, there is defective in this folding seat aspect portability, being provided with of the metal system fixture of seat cushion bottom can increase whole weight, so still remain to be improved.

[summary of the invention]

The utility model is intended to provide a kind of Blow molding chair, and it has whole lighter setting, and it can keep its default intensity of bearing the external force roof pressure under normal operating condition, and it is more convenient in carrying to be beneficial to manufacturer or common people after folding enforcement.

Technical solution adopted in the utility model is: a kind of Blow molding chair, and it includes the chair tool supporting frame that metal matter pipe fitting is articulated, and locatees respectively at the suitable paragraph of chair tool supporting frame and to assemble stamping forming seat cushion of metal matter and backrest; It is characterized in that: this seat cushion and backrest are the hollow form members that adopts plastic rubber ejaculate molding; This seat cushion both sides is respectively with three-sides-square shape frame spare fit, and its bottom side center of gravity paragraph is done to set up across the location with support component, and bestows the location with bolting element; The location is suitably highly located and bestow to the corresponding conflict of turn section that extend this support component both sides at the preceding foot rest of chair tool support body; This be nested with three-sides-square shape frame spare in the seat cushion both sides face by the rear end then correspondence be resisted against suitably height and bestow the location of rear leg; This backrest both sides leans on the top side for extending one section backstay section down partially, this backstay section is incorporated between the preceding foot rest respective tube footpath of chair tool support body with suitable packing degree cover, and the extension of place, corresponding backrest bottom side is provided with one section to sincere section on preceding foot rest, supports sincere section with this and steadily holds the location backrest.

Further feature of the present utility model also is: this hollow seat cushion both sides periphery is arranged with paragraph for being formed with one section, and three-sides-square shape frame spare is nested with in this section is arranged with paragraph.

Three-sides-square shape frame spare can be metal material and makes.

As seen, the utility model is to set up shape according to cutting off with metal matter pipe fitting to become to preset specification length and articulated into movable extension of work, or the corresponding chair tool supporting frame that folds form, be to locate seat cushion and the backrest of assembling plastic rubber ejaculate molding respectively to be assembled into a folding Blow molding chair by the suitable paragraph of chair tool supporting frame again, can be in response to the required and motor-driven use in different places, or conveniently be folded together and stack, owing to be the metal matter fixture that has replaced known seat cushion bottom surface to install with lamelliform three-sides-square shape frame spare, thereby reached and had whole lighter setting, under normal operating condition, can keep its default intensity of bearing the external force roof pressure, after folding, can be beneficial to manufacturer or common people more convenient effect in carrying.

Further specify the utility model below in conjunction with drawings and Examples.
