For the improving and replenishing of technique scheme, can increase following technical characterictic or its combination:
Described transmission device comprises one group of parallel connecting rod, crank, and connecting rod one end is connected the rod assembly lower end by the pull bar connected nail, and the connecting rod other end is connected with the crank upper end by the crank connecting link nail, and described wheel is connected the crank lower end by the wheel shaft correspondence; Described connecting rod is provided with and main body chair back reverse side recess bonded assembly connecting rod fix shaft; Have bar hole on the described crank, be provided with in the bar hole and main body chair back reverse side recess bonded assembly crank fix shaft.Pulling rod assembly during use, make rod assembly move up, drivening rod around connecting rod fix shaft rotation (be cylinder lever connecting rod an end upwards, an end of connecting crank is downward), thereby the relative crank fix shaft of drive crank slides downwards until the bar hole upper limb and contacts with the crank fix shaft, the wheel that promotion is connected the crank lower end stretches out the recess of seat support bottom surface, is convenient to roll.
Two ends of described wheel shaft are arranged in the sliding eye on the limiting stopper that is fixed in recess sidewalls.When the relative crank fix shaft of crank slides downwards when the bar hole upper limb contacts with the crank fix shaft, the wheel shaft that is connected the crank lower end is the lower edge of movement therewith sliding eye to the limiting stopper also, wheel pushed away and extended appointed positions this moment, rotated the smooth and easy obstacle that do not have.
Described rod assembly comprises one group by fixed support secured in parallel big sleeve pipe in main body reverse side recess, in the big sleeve pipe from outside to inside successively movable sleeve be connected to middle sleeve and small casing, the small casing upper end is provided with handle, handle is provided with the handle button.Pulling handle during use, in the drive, small casing and handle button move up, when wheel reaches assigned address, the middle sleeve bottom is stuck in big sleeve pipe lower end with the junction of pull bar connected nail, pull on fixed handle, small casing continues to rise, and small casing rises from from middle sleeve, reach the push-and-pull height, be suitable for the adult and push away, draw child safety seat.
Be provided with the shift locations between described middle sleeve and the small casing.Be convenient to adjust height, to be fit to adult's push-and-pull child safety seat of differing heights.
The utility model is provided with the recess space at the reverse side of seat own, thereby hold rod assembly and wheel, after it is pulled down in the car, lift moving rod assembly, by transmission device wheel is pushed away from recess and stretch, push-and-pull two is suitable, both be convenient to moving of child safety seat self, can have made its function that realizes children trolley again, one-object-many-purposes, save vehicle-mounted space, particularly be applicable to economical vehicle.

[specific embodiment]
Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present utility model is further described.
Shown in Fig. 1,3,4, child's safety seat for vehicle in the present embodiment, comprise the main body 1 that the chair back and seat support one constitute, the chair back and seat support front are coated with flexible material layer, chair back reverse side is provided with the recess that extends to the seat support bottom surface, be provided with in the recess one group by fixed support 7 secured in parallel in the big sleeve pipe 6 of main body 1 chair back reverse side recess, in the big sleeve pipe 6 from outside to inside successively movable sleeve be connected to middle sleeve 4 and small casing 5, small casing 5 upper ends are provided with handle 2, and handle 2 is provided with handle button 3.One group of parallel connecting rod 10 1 end is connected middle sleeve 4 lower ends by pull bar connected nail 8, and connecting rod 10 other ends are connected with crank 13 upper ends by crank connecting link nail 9, and wheel 14 is connected crank 13 lower ends by wheel shaft 141 correspondences; Connecting rod 10 is provided with and main body 1 reverse side recess bonded assembly connecting rod fix shaft 11; Have bar hole on the crank 13, be provided with in the bar hole by embracing piece 121 and main body 1 reverse side recess bonded assembly crank fix shaft 12.141 two ends of wheel shaft are arranged in the sliding eye on the limiting stopper 15 that is fixed in recess sidewalls.Be provided with the shift locations between middle sleeve 4 and the small casing 5.
As shown in Figure 2, during use, child's safety seat for vehicle is disassembled in car, press lower handle button 3 and carrying handle 2, middle sleeve 4 and small casing 5 rise together, when middle sleeve 4 lower ends and pull bar connected nail 8 junctions are stuck in big sleeve pipe 6 lower ends, drivening rod 10 rotates around connecting rod fix shaft 11, rise in its upper end, the lower end promotes connected crank 13 and descends, make the relative crank fix shafts 12 of crank 13 descend and contact with bar hole upper limb on the crank 13, move to the lower edge that sliding eye on the limiting stopper 15 is arrived at the wheel shaft two ends thereby drive is connected the wheel shaft 141 and the wheel 14 of crank 13 lower ends until crank fix shaft 12.At this moment, wheel 14 stretches out the seat support bottom surface, is convenient to push-and-pull.Continue to press lower handle button 3 then, promote small casing 5, select suitable positioning according to user's height, release handle button 3 is by the fixing height of selecting of shift locations.The third gear height is set usually, to be applicable to the adult of different heights.
