Compared with prior art, the utlity model has following advantage:
1, because foreleg of the present utility model, first connecting rod, third connecting rod and carriage have formed folding quadric chain, foreleg and seat are folded up, be convenient for carrying storage, and when it opens use, foreleg just in time vertical support in the seat front portion, the back leg vertical support is at the seat rear portion, back leg also is connected with foreleg with second connecting rod by first connecting rod and plays the role of fastening, seat is closely linked by pintle hook lock mechanism and chair leg, thus the utlity model has sound construction, stressed evenly, the advantage of folding convenient.
2, because the utility model is provided with pintle hook lock mechanism at the lower surface of seat, when opening use, the dop of pintle hook lock is stuck under the effect of spiral compression spring in the spacing card, and seat and chair leg are closely linked; When needing to fold, touching the button inwards just to make pintle hook lock mobile backward, and the dop of pintle hook lock will be separated from spacing card, thereby seat separates with the chair leg.So the utility model is not fragile opening when using seat and chair leg in conjunction with firmly.
3, because the utility model being provided with can be with the spring reset mechanism of seat jack-up, and when opening use, seat and chair leg are combined closely, piston rod presses spiral compression spring; Need when folding, seat separates with the chair leg, piston rod jack-up seat automatically just under the effect of spiral compression spring, and seat can not fall automatically under the effect that does not have external force, thus the chair under the folded state can vertically be placed under the situation of having no backing.So the utility model can fold placement whenever and wherever possible, it is convenient to carry storage.
4, because the utility model chair leg lower end is provided with return pulley, so the utility model conveniently moving in use.
