Summary of the invention

The purpose of this utility model is to provide a kind of convenient type folding seat at above-mentioned weak point, have base frame tube, backing tube, rear foot tube, forward and backward cross pipe, the chair lining is sleeved on base frame tube and the backing tube, the people is sitting on the lining, owing to the self-weight press support of human body makes the lining stretching, can not cause lining to become soft because of the increase of access times.Owing to be provided with forward and backward cross pipe, rear foot tube, base frame tube, backing tube, chair shelf structure intensity is increased, form triangular structure at chair frame both sides pipe fitting, back pole-bracket good stability on people's seating, weight capacity is big, can guarantee the folding seat safe handling.

The convenient type folding seat takes following scheme to realize: the convenient type folding chair structure comprises base frame tube, backing tube, rear foot tube, front cross pipe, rear cross pipe, stay pipe, lining.Backing tube and base frame tube interconnection, the rear foot tube upper end is connected with backing tube by rotating connector, the base frame tube rear end is sleeved on the rear foot tube by the rear foot tube sliding part, the rear cross pipe upper end is connected with backing tube top with connector by the U-shaped hinge, the rear cross pipe bottom links to each other with rear foot tube by the U-shaped hinge, front cross pipe top is connected with base frame tube with connector by the U-shaped hinge, and the front cross pipe bottom is connected with the backing tube lower end by the U-shaped hinge.The stay pipe upper end is connected with base frame tube by connector, and the stay pipe lower end is sleeved on the backing tube lower end by the stay pipe sliding part.Lining is sleeved on backing tube and the base frame tube.

In the chair frame both sides of folding seat, backing tube, rear foot tube, base frame tube constitute the triangle structure that is located by connecting by rotating connector, rear foot tube sliding part.

Front cross pipe top can be provided with handrail tube, is used for the soft handrail of suit.Soft handrail one end is sleeved on the handrail tube, and the other end is sleeved on the backing tube, forms the folding seat of Armrest.

When the convenient type folding seat is used, catch backing tube, handrail tube or base frame tube outwards to push open, the rear foot tube sliding part upwards slides along rear foot tube, and the stay pipe sliding part, can be decontroled folding seat easily and use to lower slider along backing tube.Catch the inside folding of backing tube, handrail tube or base frame tube when folding, to lower slider, the stay pipe sliding part upwards slides along backing tube the rear foot tube sliding part along rear foot tube, can easily the folding seat folding be integral to put into bag and carry.

The convenient type folding seat is reasonable in design, compact conformation, use, convenient folding, because having base frame tube, backing tube, rear foot tube, forward and backward cross pipe, chair lining is sleeved on base frame tube and the backing tube, the people is sitting on the lining, owing to the self-weight press support of human body makes the lining stretching, can not make lining become soft because of access times increase.The utility model folding seat chair shelf structure intensity is good, constitute the triangle structure that is located by connecting at chair frame both sides backing tube, rear foot tube, base frame tube by rotating connector, rear foot tube sliding part, structural stability is good, and weight capacity is big, can guarantee the folding seat safe handling, long service life.
