The utility model relates to a frame which can be used in a bicycle and a tricycle, comprising a main frame, a rear vertical fork and a rear flat fork; the rear vertical fork and the rear flat fork are movably connected with the main frame. The utility model which is suitable for various bicycles and tricycles can stretch the cycle frame conveniently, and then, the bicycle frame is changed to the tricycle frame.
Description
The utility model relates to a kind of vehicle frame that can be used as bicycle and three-wheel vehicle.
Existing cycle frame generally all is fixedly to be welded by main car frame and rear stays, back chain stay.Its function singleness only can be used as bicycle.
The purpose of this utility model provides a kind of extensible cycle frame of tricycle frame that is, makes bicycle can become three-wheel vehicle easily, thereby expands the function of bicycle, reaches the effect of one-object-many-purposes.
The utility model is made up of main car frame, rear stays, back chain stay, its rear stays or back chain stay have at least one to be to flexibly connect with main car frame, be that the utility model can be formed by main car frame, the back chain stay of captiveing joint with main car frame with the rear stays that main car frame flexibly connects, also can form by main car frame, the rear stays of captiveing joint with the back chain stay that main car frame flexibly connects with main car frame, can also be by main car frame, be the rear stays of flexible connection with main car frame, back chain stay is formed, its flexible connection can be hinge type in succession, bolt-type connection etc.By rotate the rear stays that flexibly connects with main car frame or (with) the back chain stay, make movable rear stays or (with) the back chain stay stretches to the axial both sides of axletree, can reach the purpose that cycle frame is stretched to tricycle frame.
The utility model is simple in structure, only need with the back chain stay of captiveing joint of existing various cycle frame with main car frame or (with) rear stays changes flexible connection into and can realize.Be applicable to various bicycle.Be particularly suitable for children and take turns car--children hour vehicle frame is stretched and do tricycle frame, make three-wheel vehicle, increase stability, when children grow up by bike, original tricycle frame can be drawn in, be adapted as bicycle easily, adapt to the needs of the different times of child growth.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 is the structural representation of embodiment 1
Fig. 2 is that the A of the attaching parts 4 among Fig. 1 is to partial view
Fig. 3 is the structural representation of embodiment 2
