Abstract

The utility model relates to a stationary type folding chair. The stationary type folding chair comprises a main supporting frame and a backrest connected with the upper part of the main supporting frame, wherein a seat surface is connected with the middle part of the main supporting frame, and slides up and down at the lower part of the main supporting frame by virtue of a lantern ring, so as to be unfolded and folded. When the stationary type folding chair is used, people only need to pull down the seat surface, a supporting rod drives the lantern ring to slide to a lantern ring limited slip ring at the lower part of the main supporting frame, the seat surface is just in an unfolded state, and the lantern ring limited slip ring stops the lantern ring from sliding, so that people can sit down and rest securely; after rest, the seat surface can be lifted up conveniently, and a rotation axis is pressed by an elastic pressing strip, so that the seat surface can not be automatically unfolded under the condition of no external force. By applying the stationary type folding chair, congestion in public places can be alleviated, people can be rapidly evacuated in emergency, and labour intensity and difficulty in a clean-keeping process are also reduced for clean-keeping workers.

Description

Stationary type folding chair

Technical field

The utility model relates to the seat field of establishing for convenience of interim rest of the public in the occasions such as the corridor, station, bus-stop, theater of public arena Zhong Ru hospital, relates in particular to a kind of stationary type folding chair.

Background technology

The seat of establishing for convenience of interim rest of the public is in public a kind of requisite communal facility, the seat of establishing for interim rest of the public in these occasions in prior art is mostly foldable chair not, these not the shortcoming of foldable chair for easily cause jam in flow of personnel peak period, if meet the rapid evacuation that emergency case is unfavorable for personnel, moreover because it is not collapsible, its chair top and backrest can be always in opening shape, when idle, cannot avoid adhering to of fine dust, this has increased the labour intensity of cleaning worker virtually, the dead angle because keep a public place clean difficulty and omission that its not folding characteristic causes cleaning worker can increase floor under seat when to cleaning floor are kept a public place clean.

Summary of the invention

The purpose of this utility model is to provide and is a kind ofly fixed on outside corridor on body of wall or the stationary type folding chair on floor, be intended to solve the seat of establishing for convenience of interim rest of the public in public arena in prior art and do not possess foldability, once arrive in emergency case, it is unfavorable for virtually having increased the labour intensity of cleaning worker, the problem of difficulty in personnel's rapid evacuation and the process of keeping a public place clean.

In order to realize above object, the technical scheme the utility model proposes is as follows.

Stationary type folding chair, comprise main backstop and be connected to the backrest on main backstop top, chair top inner side is by rotatably linking the middle part that is connected on main backstop, chair top outside is connected with post upper by rotatable button, support bar lower end is connected with the collar by rotatable button, the collar is arranged on the body of rod of main backstop bottom, the upper and lower slip by the collar on the body of rod of bracing frame bottom, thereby drive, support bar is accomplished to open, foldable base seat.

Described main backstop is that top is fixed with backrest, middle part link chair top, the bottom body of rod can make the collar slide up and down, and at the collar, slides into chair top in opened condition time, on the body of rod of main backstop bottom, have a circle to be greater than the collar on-slip ring of collar internal diameter, there is fixed bolt hole the lower end of main backstop.

Described backrest is the same with backrest structure of the prior art.

Described chair top is chair top general in prior art.

The rotatable button of described chair top is for installing elastic layering additional in the inner both sides of the rotatable turning cylinder of detaining, the part of the turning cylinder that elastic layering contacts is square, when chair top and backrest are rugosity, the planar section of the turning cylinder that the elastic layering of establishing in turning cylinder is just in time pressed, so can guarantee that chair top can not open voluntarily in the situation that there is no external force.

Described support bar is that upper and lower end respectively has a rotatable button, upper end rotatably link the avris front end that is connected on chair top, the rotatable button of lower end is connected with the collar.

The described collar is hollow form hollow cylinder, and it is enclosed within main backstop bottom, and its outside is connected with the rotatable button of support bar lower end.
