Vehicle body of the present utility model can select for use rigid plastic or other hard material to make.Three parts before, during and after vehicle body is made, as Figure 12, Figure 11, shown in Figure 10: anterior (9) all adopt hinging type to be connected with middle part (8), middle part (8) with rear portion (11).Vehicle body middle part (8) bottom surface front edge and middle part, bottom surface are processed with hinged joint hole (1), respectively there are two spring tongues (2) and (3) in two sides, its structure is as shown in Figure 4: have stationary spring (4) on the latch (5) in latch groove (22), be with spring (6) on the latch at its rear portion (5).Latch (5) can be extracted from the jack (7) of body forward structure (9) with external force.Eliminate external force, latch (5) inserts jack (7) by the elastic force of spring (6), makes vehicle body middle part (8) and body forward structure (9) fixing.In like manner, spring tongue (3) is transferred to or is inserted body tail jack (10) and can realize and the separating or fix of body tail (11).

Also respectively there are two shock attenuation units (12) two sides, vehicle body middle part, its structure is as shown in Figure 5: have damper spring (14) in vibration damping groove (13), damper spring (14) bottom is connected with an intubate (15) that can slide up and down along vibration damping groove (13), vibration damping latch (16) is connected on the forward and backward support, can rotate along support when separating with shock attenuation unit (12), the anti-skid stud (23) that prevents its downslide is arranged on the kickstand.The structure of vibration damping latch (16) is identical with (3) with the spring tongue (2) at vehicle body middle part: there is a latch (17) vibration damping latch (16) inside, has stationary spring (18) on it, and the rear portion has spring (19).With external force latch (17) is extracted from intubate (15), spring tongue (16) is separated with vibration damping groove (13).Elimination external force, latch (17) leans in the elastic force tubular stinger (15) of spring (19), and can slide up and down along vibration damping groove 13.

The body forward structure side has and the cooresponding jack of spring tongue (2) (7), as shown in figure 12: can adopt different jack (7) to be connected with spring tongue (8), reach body forward structure (9) and the fixing effect of middle part (8) different angles.Body forward structure (9) edge also has two hanging holes (20).

The side of body tail (11) has and the cooresponding jack of spring tongue (3) (10), as shown in figure 10: can adopt different jack (10) to be connected with spring tongue (3), reach body tail (11) and the fixing effect of middle part (8) different angles.The edge of body tail (11) also has two hanging holes (21).

Have two links (26) on the crossbeam of the handle rack of vehicle frame (25), the lower end has the binding bolt (28) that can slide and can fix with it in the guide groove (27) of front frame (36), its structure is as shown in Figure 8: handle rack (25), after poppet (35) adopts being rotatably connected of rivet type with front frame (36).Also have hook (29) on the front frame (36), have clothes-hook (30) on the after poppet (35).Hook (29) is hung on the clothes-hook (30) the fixedly front and back support of dolly.

Wheel (38) adopts common wheel, have stop motion mechanism (31) on the wheel, its structure such as Fig. 6, shown in Figure 7: stopping gear (32) is coaxial with wheel (38), be installed between support and the wheel and be fixed on the wheel inboard, on the kickstand of its top " fourth " font stop pin (33) is housed, stop pin (33) adopts the axle connection mode with vehicle frame, can rotate up and down along axle (34).

When doing the perambulator use, with three parts before, during and after slotting rod (37) connection of the hinged joint vehicle body, regulating spring latch (2) and (3) and kickstand hang up hook (29), referring to state shown in Figure 1.The shock attenuation unit of vehicle body (12) is fit to dolly exercises on the road surface of injustice, plays the effect that connects vehicle body and vehicle frame and vibration damping.Vehicle body middle part (8) latter half of put article such as clothing, is convenient to go out carry thing.

Regulating spring latch (2) and (3) keep flat vehicle body, referring to shown in Figure 2, can be used as the dolly of transportation, make in transporting thing at ordinary times or travelling away from home.

Regulating handlebar frame (25) makes it be in plumbness, hang up cradle rope (24) by link (26) and hanging hole (20) and (21), regulate the vibration damping latch (16) of shock attenuation unit (12), vibration damping latch (16) is separated with vehicle body, rotate latch (16) and make it towards avris.Anti-skid stud (23) can prevent that vibration damping latch (16) from gliding.Referring to state shown in Figure 3, can be used as children and use with cradle, solved the problem that family is difficult for being provided with the children special-purpose cradle.

Have stop motion mechanism (31) on the wheel, when using at ordinary times, regulate stop motion mechanism (31), state makes stopping gear (32) separate with " fourth " font stop pin (33) as shown in Figure 7, but just normal operation of wheel.The car amount needs when motionless, and as cradle, scalable " fourth " font stop pin (33) makes it block stopping gear (32) and wheel can not be turned round reach the purpose of stop, state as shown in Figure 8.

When not using, the hook on scalable vehicle frame and the kickstand (29) makes its state preservation as shown in Figure 9, saves shelf space, and dolly is detachable when needing, and vehicle body, vehicle frame are placed respectively.
