Embodiment
The technical solution of the utility model is done below in conjunction with Figure of description and specific embodiment and further explained in detail
State.
As shown in Fig. 3, Fig. 4 and Fig. 5, the present embodiment provides a kind of upset folding seat, including：Supporting 110, axle center 120 and seat
Plate 130；
The supporting 110, positioned at the outside of the seat board 130；
The axle center 120, both ends are fixedly connected with the supporting 110, and appearance is fixedly connected with the first locating part 121；
Wherein, described be fixedly connected can be welding；
The seat board 130, both sides are provided with opening, and the opening is penetrated inside the seat board 130 for the axle center 110；
The seat board 130 includes：The locating part 132 of skeleton 131 and second, second locating part 132 are located at the skeleton
It is fixedly connected in 131 and with the skeleton 131；Wherein, the skeleton 131 and second locating part 132 are all the seat board
130 inside composition structure, described be fixedly connected can be welding；
When the seat board 130 rotates around the axle center 120, first locating part 121 and second locating part 132
Interaction so that the seat board 130 is predetermined angle relative to the anglec of rotation in the axle center 110.
In the present embodiment in order to avoid the seat board is during upset, by user's hand caused by flip angle is excessive
It is clipped between compartment wall and seat board 130, introduces the first locating part 121 in the outer surface in axle center 120 in the present embodiment, and
The second locating part 132 is introduced in skeleton 131.Second locating part 132 is fixedly connected with the skeleton 131, if described
Skeleton 131 rotates around the axle center 120, then second locating part 132 can rotate with the rotation of the skeleton 131.
It can be interacted between the locating part 121 of the second locating part 132 and first in the present embodiment, when the seat board
After 130 rotate to certain angle relative to axle center 120, first locating part 121 can prevent second locating part 132
Continue to move, so as to prevent the seat board 130 from continuing to move, have the function that to make spacing so that the seat board 130 relative to
The axle center 120 is only capable of in predetermined angle range of motion.
