Fig. 1 is the tricycle block diagram; Fig. 2 is three ski bob block diagrams; Fig. 3 is the two-wheel bicycle block diagram; Fig. 4 is two ski bob block diagrams; Fig. 5 is single the feet step on the ground three-wheel vehicle block diagram; Fig. 6 is single the feet step on the ground three ski bob block diagrams; Fig. 7 is single the feet step on the ground two-wheel car block diagram; Fig. 8 is single the feet step on the ground two ski bob block diagrams.

For achieving the above object, the utility model contains by four kinds of pipe fittings 16,17,19 and 23 and the car body that is assembled into of axle 9 at least by one, by the handlebar that pipe fitting 18 and handle 31 form, seat cushion 5(is as shown in Figure 1) or pedal 36(is as shown in Figure 5) consist of with at least a following front wheel driving device that links to each other with front fork 19 and the moving device of rear company that is connected on the bend pipe 23.

Embodiment in conjunction with the accompanying drawings further specifies as follows:

Two kinds of pipe fittings 16,17 each two, by connecting clamp 8, and bolted connection, be assembled into crossbeam, the rear end of pipe fitting 23 and pipe fitting 16 is with being connected clamp 8 and bolted connection, constitute car body, two pairs of holes of clamp 3 and two pipes of front fork tube 19 are respectively bolted connection, cambered axle 9 and clamp 3 are for being threaded, by connecting clamp 8 and bolt crossbeam 16,17, the handlebar that bend pipe 18 and handle 31 are formed links together, in the hole of the attaching parts 8 on the threaded shaft tubular stinger 17 below the seat cushion 5 (as shown in Figure 1), or the stretcher 36(that fixes on pipe fitting 16 is as shown in Figure 5) and at least a following front driving device and back linkage composition, as:

The axle that is connected on clamp 8 and bolt and the wheel 1 by front fork pipe fitting 19 usefulness is connected, crank on the axle is connected with pedal 11, front fork 19 and pedal 11, wheel 1 are formed front driving device, bend pipe 23 is connected with axle 26 with threaded sleeve with connecting clamp, axle 26 is running-fit with the hole of sleeve pipe, and form the back linkages with two wheels 2, constitute tricycle shown in Figure 1;

Connect clamp 8 by front fork 19 usefulness and link to each other with axle 13 with bolt, the threaded shaft of axle 13 lower ends is connected with the screw of ski 12 upper ends, constitutes front driving device.Ski 12 is drawn with rope in both sides at axle 13, promptly travel forward, pipe fitting 23 is connected with axle 29 with bolt with connecting clamp 8, the two ends of axle 29 are connected ski 14 with bolt with connecting clamp 8 with axle 29, form the back linkage, constitute three ski bobs shown in Figure 2;

By the front driving device identical and by axle 25 with tricycle, connect clamp 8 and wheel of bolted connection 2 composition back linkages, constitute two-wheel bicycle shown in Figure 3;

By front fork 19, preceding ski 12, adapter shaft 13 connects into front driving device, and the back is mounted to the back linkage by axle 25 and sled 14; Constitute two ski bobs shown in Figure 4.During use, children can pushed away in the back by the adult on cushion and advance, and the rope that also can help pull a cart in front on axle 13 or axle 9 advances;

Connect clamp 8 and bolt and wheel 1 by front fork 19 usefulness and be assembled into front driving device, the back connects clamp 8 and bolt by axle 37, is assembled into the back linkage with two wheels 2, constitutes single the feet step on the ground three-wheel vehicle shown in Figure 5.Be applicable to the less and relatively poor children of balanced capacity of age.During use, both hands walker handle, single the feet step on the ground, another pin one advances with pedaling;

By front fork 19, connecting clamp 8 is connected with adapter shaft 13 with bolt, the threaded shaft of axle 13 lower ends and the screw of preceding ski 12 are assembled into front driving device, the back is by major axis 29, ski 14 after two, connect clamp 8 and bolt and be assembled into the back linkage, constitute single the feet step on the ground three ski bobs shown in Figure 6;

Connect clamp 8 and bolt and wheel 1 by front fork 19 and be assembled into front driving device, the back is by axle 25, and connection clamp 8 and bolt and a wheel 2 are assembled into the back linkage, constitute single the feet step on the ground two-wheel car shown in Figure 7;

By front fork 19, connect clamp 8 and bolt, adapter shaft 13, preceding ski 12 is assembled into front driving device, and the back is assembled into the back linkage by ski 14 behind 25, one on the axle, constitutes single the feet step on the ground two ski bobs shown in Figure 8.

The utility model has the advantages that: 1. can by the assembling of being done it yourself by children with the exploitation children's intelligence, be again the building block system bicycle of motion amusement; 2. single the feet step on the ground sled car is children's one the feet step on the ground, and a pin stands on the car, is a kind of motion, can enjoy again the enjoyment of slide plate, and more safe and reliable than traditional slide plate.
