It is dynamic, it takes and is placed in installation base body 101 after the disengaging clip plate 501 of seat board 201, user can be sitting on seat board 201 at this time, when need
It when wanting function of leaning, can be respectively inserted in groove 702 by thumb and index finger, hiding pin ontology 701 is pinched out, rotation conversion base
Playscript with stage directions body 301 makes desktop 403 upward, pulls up desktop 403, and hiding pin ontology 701 is turned back to first behind hole 205
It is then passed through the fixation that third completes 403 height of desktop across hole 402, the present invention is changed to Fig. 2 from Fig. 1 and completes dilatation shape at this time
State to comfort conditions transformation.
Dilatation seat in a kind of subway carriage of the invention, its working principle is that:
As shown in Figures 1 and 3, multiple installation base bodies 101 of the invention are fixedly connected sequentially together from left to right, it will
The front end of multiple installation base bodies 101 is fixedly connected on compartment inner wall, completes the installation of side seat, completion seat similarly
Two sides installation；Under Fig. 1 state, the present invention is dilatation state, and the seat board 201 as seat is that vertical state reclines compartment inner wall,
Each funtion part installed thereon as provide safety with convenient flexible handle 6 and play support dependence conversion base station 3 with it is hidden
Hiding desktop 4 is in " hidden state ", workable space in compartment is increased, in addition to standing before an installation base body 101
Outside two people, knapsack etc. can be placed on to the upper end of installation base body 101, provide convenience for passenger, prevent from putting it on the ground knapsack change
It is dirty, it can also be held by being produced the flexible handle 6 in handle holding tank 206 with hand, when preventing subway from starting or stopping
The inertia force for generating left and right directions makes vehicle passenger's astasia, can hang up polybag in the lower end of flexible handle ontology 601, fold
The small articles such as umbrella can liberate the hand of passenger, and the small articles such as 602 folded umbrella of protrusion slip, and recess portion 603 is convenient for small articles such as folded umbrellas
Be stuck in it using self gravity, flexible handle ontology 601 be rotatably connected on by axis on seat board 201, but the axis with
Seat board 201 is fixedly connected, and has certain frictional force both while being rotatablely connected flexible handle ontology 601 and the axis, should
Frictional force can using the usual technological means of those skilled in the art such as rubber ring so that make flexible handle ontology 601 or else by
Any angle is capable of fixing in the case where external force, clip plate 501 guarantees flexible handle ontology using the elastic force that compressed spring 504 provides
601 is in a vertical state；Seat board 201 can be withheld when fewer in number in compartment backward, make its rotation, when seat board 201 rotates
Clip plate 501 moves backward, and takes and is placed in installation base body 101 after the disengaging clip plate 501 of seat board 201, user can sit at this time
It on seat board 201, when needing function of leaning, can be respectively inserted in groove 702 by thumb and index finger, by hiding pin ontology
701 pinch out, and rotation conversion base station ontology 301 makes desktop 403 upward, desktop 403 are pulled up, by hiding pin ontology 701
It turns back to first and is then passed through the fixation that third completes 403 height of desktop across hole 402 behind hole 205, it is of the invention from Fig. 1 at this time
It is changed to Fig. 2 and completes the transformation of dilatation state to comfort conditions；The present invention is in the way of automatic 5 fixed base plate 201 of fastener device
Suitable for the variation tendency of subway flow of the people, such as when flow of the people peak, fixed base plate 201 is rotated up, the fixation of rotation
Seat board 201 is got between clip plate 501 and compartment inner wall using the card of bending section 502 and completes vertical state, and compartment dilatation is completed, when
Flow of the people peak period is later low flow of the people state, and user directly rotates into fixed base plate 201 after seat state leaves, Gu
Reservation plate 201 will not be sprung back, and make next user that can directly sit down, and when reaching next peak period, this state is almost tieed up
It has held one day, it is practical without adjusting repeatedly.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
