Folding-type rotary aluminum-plastic chair

Abstract

The invention discloses a folding-type rotary aluminum-plastic chair, which can be fully folded conveniently and rapidly and is convenient to store, transport and carry due to small packaging volume. The folding-type rotary aluminum-plastic chair consists of a pedestal assembly, a seat assembly and a back assembly, wherein slide block spacing rings are mounted on the inner sides the two slide blocks on each guide rail and on the outer guide rail of one of the slide blocks respectively; a seat-positioning lock is mounted on the fixing plate of a swivel bearing; the other horizontal rod on the upper part of a bracket is clamped in the clamping slot of the seat-positioning lock; a handrail and a seat board fixing ring are moveably connected and locked by a handrail-positioning lock; the lower end part of a back extension tube is hinged with the upper part of a back-positioning lock; the lower part of the back-positioning lock is fixedly connected with the corresponding seat board fixing ring; a pedal assembly can also be mounted between the seat board fixing ring and the pedestal fixing ring; and a baffle plate is hinged on the upper end part of the back extension tube.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic chairs, in particular to a foldable rotating aluminum-plastic chair. Background technique [0002] Now a rotatable aluminum-plastic chair is composed of a base, a seat plate, a back pipe, a back plate, a seat plate fixing ring, a bracket, an armrest, a pressing block, a guide rail, a slider, and the like. The guide rail is fixed in the fixed ring of the base, and the slider is set on the guide rail; the lower end of the bracket is hingedly connected with the slider, and the upper end of the bracket is fixed on the rotating bearing fixed plate through a pressure block, and the slider can only move in the same direction; the seat is easy to be eccentric, The seat can only be kept in the center position by manually adjusting the slider; the folding of the bracket can only be realized by manually loosening the screws of the pressing block. The handrail is welded on the fixed ring of the seat...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned rotating aluminum-plastic chair has the following disadvantages: ①The slider can only slide to one side, and the center of the seat can easily deviate from the center of the base, so the center of the seat can only be controlled by manually adjusting the slider to keep it at the center of the base

Moreover, when the bracket needs to be folded, it is necessary to manually unscrew the screw of the pressing block to fold it. There is no mechanism to limit the stroke of the slider. After folding, it is difficult to ensure that the bracket is located in the center of the base.

②Because there is no foot pedal, leisure people sitting on the aluminum-plastic chair can only put their feet on the ground or hang in the air. Although the aluminum-plastic chair can rotate, the user still feels uncomfortable

Because when rotating, the feet will rotate with the aluminum-plastic chair, and the rotation of the feet in the air will make the user feel very tired

③The armrest is fixed on the seat plate fixing ring, and cannot be adjusted in height or folded; the back assembly is fixed on the seat plate fixing ring, and cannot be folded; it takes up a lot of space when packing, and is extremely inconvenient to carry
