Technical Field

The invention relates to the field of folding chairs, in particular to a multi-person folding chair.

Background

The folding chair can be folded and conveniently taken, but the existing folding chair has limited seats, can not increase the positions of the seats, can not simultaneously sit down a plurality of people, has limitation, and greatly reduces the working quality.

Thus, further improvements are needed in the existing folding chairs.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a multi-person folding chair.

In order to achieve the purpose, the invention adopts the following scheme:

a multi-person folding chair is characterized in that: the turnover support device comprises a first plate, a turnover backup plate is connected and arranged on the first plate, second turnover plates are respectively connected and arranged on two sides of the first plate, and turnover support legs are connected and arranged on the surfaces of the second turnover plates.

The multi-person folding chair is characterized in that the turnover backup plate comprises a second plate arranged at the edge of a first plate, the first plate and the second plate are hinged through a first rotating shaft, a second groove is formed in the side wall of the second plate, a first groove is formed in the side wall of the first plate, a second transverse shaft is arranged on the second groove, a first transverse shaft is arranged on the first groove, a first connecting rod is movably arranged on the second transverse shaft, a second connecting rod is connected onto the first transverse shaft, and the first connecting rod and the second connecting rod are hinged with each other

The multi-person folding chair is characterized in that the second turnover plate comprises an L-shaped turnover plate arranged on one side of the first plate, the end part of the L-shaped turnover plate is hinged with the side edge of the first plate through a second rotating shaft, a limiting block is arranged at the hinged position of the L-shaped turnover plate and the first plate, and connecting grooves connected with the other L-shaped turnover plate are uniformly distributed on the surface of the L-shaped turnover plate.

The multi-person folding chair is characterized in that the overturning supporting legs comprise overturning legs arranged below the second overturning plate, the overturning legs are hinged to the second overturning plate through a third rotating shaft, and second limiting blocks are arranged at the end parts of the overturning legs.

In summary, compared with the prior art, the invention has the beneficial effects that:

the folding chair has the advantages that the number of seats is greatly increased, the positions of the seats can be increased, a plurality of people can sit down at the same time, the limitation is reduced, the working quality is greatly increased, the structure is simple, and the use is convenient.
