Abstract

The utility model relates to a frame of a bicycle, which is easy to be moved and comprises a knee pipe (1), a vertical pipe (6), a middle joint (3), a vertical fork (5), a horizontal fork (4) and a front pipe (7), wherein, the lower end of the knee pipe is connected with the middle joint, and the lower end of the vertical pipe is also connected with the middle joint. The utility model also comprises a connection pipe (2), both ends of the connection pipe are connected with the lower parts of the knee pipe (1) and the vertical pipe (6) to form a triangle, so the structure is comparatively firm. The position of the connection pipe is near the center of gravity of a bicycle, the height of the connection pipe is just enough for the bicycle to be lifted after held by hand, so the utility model is comparatively convenient when the bicycle is moved upstairs.

Description

Frame of bicycle easily moving

The utility model relates to a kind of structure of bicycle rack.

The vehicle frame oldfashioned of bicycle is a triangular structure, though firmly, because there is a crossbeam front, inconvenience during preceding getting on the bus, and heavy.Have a kind of vehicle frame of woman style car to adopt an extra heavy pipe to bend to U-shaped, as vehicle frame, style is novel, but can not grip part during carrying, thereby very not convenient.

The purpose of this utility model is the structure that proposes a kind of vehicle frame, sound construction and bicycle convenient in carrying.

This bicycle rack of being convenient to move comprises bend pipe, standpipe, center tap, upright fork, chain stay, preceding pipe and a connection pipe, the lower end of bend pipe links to each other with center tap, the lower end of standpipe also links to each other with center tap, and an end of upright fork and chain stay is connected to each other, and the other end is connected on standpipe and the center tap.The two ends of connection pipe link to each other with the bottom of bend pipe and standpipe respectively.

This bicycle rack, because bend pipe, standpipe and connection pipe are formed a triangle, thereby texture ratio is more firm, and the position at connection pipe place is near the center of gravity place of bicycle, bicycle can be mentioned after the just handy hand of its height grips, thereby carry, more convenient when particularly going upstairs.

Accompanying drawing 1 is the constructional drawing of this vehicle frame;

Accompanying drawing 2 is the constitution diagram after this vehicle frame is assembled into bicycle.

(1) is bend pipe as shown in Figure 1, and the part of a bending is arranged at its bottom, and (6) are standpipe, and the lower end of bend pipe and standpipe all links to each other with center tap (3).The bottom of the two ends of connection pipe (2) and bend pipe (1) and standpipe (6) fixes, and constitutes a firm triangular structure.Because some is crooked for a bend pipe, thereby the moulding of whole vehicle frame is relatively more novel.The position of connection pipe is lower, is suitable for having carried bicycle with the hand gripping, gets on or off the bus when being convenient to ride again.Bend pipe (1) can be made of thicker pipe, and for example diameter is the pipe of 30～40mm, connection pipe (2) can with thinner pipe for example diameter be the pipe of 16～22mm, it can be straight, also can be some bending.Standpipe then can adopt pipe or with the bend pipe identical pipe thinner than bend pipe to make, and for example diameter is 22～35mm.(5) are chain stay for upright fork, (4) among the figure, and an end of upright fork and chain stay is connected to each other, and the other end is connected respectively on standpipe (6) and the center tap (3).(7) be preceding pipe, link to each other with the upper end of bend pipe (1).

As shown in Figure 2, this vehicle frame relatively is suitable for using on small-wheel bicycle, 24～20 cun small-wheel bicycle for example, and not only sound construction, novelty, and move conveniently.
