Abstract

The utility model relates to a bicycle-tricycle dual-purpose vehicle which not only can be used as a bicycle but also can be transformed into a small tricycle. The bicycle-tricycle dual-purpose vehicle is characterized in that a support frame, a three-wheeled shelf, a third wheel and a hook are additionally arranged at the right side of a rear wheel of a common bicycle, wherein a round bar on the three-wheeled shelf is sleeved in a shaft sleeve on the lower end of the support frame and can rotate around the shaft sleeve; the third wheel supported by a mandrel is arranged below the middle part of an outer shelf side of the three-wheeled shelf and is in parallel with the rear wheel of the bicycle; and the hook is arranged above the outer shelf side. When not used for loading, the three-wheeled shelf is rotated upwards around the shaft sleeve and is hung on a triangular frame by using the hook, and then the bicycle-tricycle dual-purpose vehicle is used as the bicycle; when used for loading, the three-wheeled shelf is put down, the third wheel touches the ground and rolls forwards with the vehicle, and then the bicycle-tricycle dual-purpose vehicle is used as the small tricycle; and goods can be put on the three-wheeled shelf and can be safely carried to achieve the purpose of transformational uses of the bicycle and the small tricycle.

Description

Three-wheeled mopeds voluntarily,

Affiliated technical field

The utility model relates to a kind of vehicle that can manned loading, especially can use as bicycle, can be transformed into again that kiddie car uses voluntarily, three-wheeled mopeds.

Background technology

At present, known bicycle mainly is made of mechanisms such as front and back wheel, headstock, vehicle frame, seat board, back shelf, chain gearing and brake gears, and people travel by bike, have not only brought convenience to traffic, simultaneously, can also utilize car after shelf deliver a small amount of goods.But bicycle now is because the back shelf location is higher, and area is less, and more when heavier when goods, back shelf fail to lay down, but also may be higher because of the goods center of gravity, and the driving shakiness is fallen down easily, causes safety traffic hidden danger.

Summary of the invention

Higher less in order to overcome existing bicycle because of the back shelf, when delivering more heavier goods, crank causes the deficiency of safety traffic hidden danger easily, the utility model provide a kind of voluntarily, three-wheeled mopeds, this motor moped can not only be made bicycle and use, and brings traffic convenience to the people, and when goods more when heavier, car can be transformed into kiddie car and use, easily carry cargo, for the user has brought convenience.

The technical scheme that its technical matters that solves the utility model adopts is: on bicycle rear right side commonly used, set up bracing frame, three-wheel shelf, third round and hook totally four part bodies.Bracing frame is made of two poles and an axle sleeve, and two poles are separated certain distance and vertically installed, and its upper end is fixedly mounted on respectively on the axis of bicycle rear and on the vehicle frame cross bar, and the axle sleeve down hand welding is in the lower end of two poles; The three-wheel shelf are formed rectangle structure by a round bar and three frame limits, and round bar is sleeved within the axle sleeve, can rotate around axle sleeve, so that the three-wheel shelf are hung up or put down; Third round motive axle bearing is installed in the below at middle part, three-wheel shelf outrigger limit, and parallel with bicycle rear; Hook is installed in the top on three-wheel shelf outrigger limit.When not loading, the three-wheel shelf are upwards changeed around axle sleeve, on the spider that hangs over car, then car is done the bicycle use; When the needs loading, the three-wheel shelf are put down, the sub-kiss the earth of third round rolls forward with car, and this car is just made little three-wheel and is used, and goods is placed on above the three-wheel shelf, but just safe carriage has reached the purpose that bicycle, kiddie car conversion are used.

The beneficial effects of the utility model are, the three-wheel shelf are hung up, and can make bicycle and use, and the three-wheel shelf are put down, and can be transformed into kiddie car and use, and only make the three-wheel shelf and third round that can rotate around axle sleeve on the bicycle rear right side, and are simple in structure.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structure principle chart after the utility model three-wheel shelf put down.

Fig. 2 is the structure principle chart after the three-wheel shelf are hung up.

1. bicycle rears among the figure, 2. vehicle frame cross bar, 3. trailing wheel axis, 4. chain drum rotating shaft, 5. two poles, 6. axle sleeve, 7. round bar, 8. three frame limits, 9. third round, 10. hook.

The specific embodiment

In Fig. 1, bicycle rear (1) is installed on the trailing wheel axis (3), the two ends of vehicle frame cross bar (2) connect with trailing wheel axis (3) and chain drum rotating shaft (4) respectively, the upper end of two poles (5) be fixedly mounted on respectively that trailing wheel axis (3) is gone up and vehicle frame cross bar (2) on, axle sleeve (6) is welded on the lower end of two poles (5), round bar (7) is sleeved within the axle sleeve (6), article three, frame limit (8) form rectangle structure with round bar (7), be installed in the below at middle part, three-wheel shelf outrigger limit behind third round (9) the motive axle bearing, parallel with bicycle rear (1), hook (10) is installed in the top on three-wheel shelf outrigger limit.

The utility model most preferred embodiment: the long 40cm of three-wheel shelf, wide 30cm, liftoff high 15cm, the sub-diameter 13cm of third round.

Claims
