Abstract
The utility model discloses a rotatable bicycle handlebar vertical pipe assembly which comprises a shaft casing pipe and a handlebar vertical pipe. The shaft casing pipe is installed at the upper end of a headset of a bicycle head pipe, one end of the handlebar vertical pipe is vertically locked to the shaft casing pipe through an eccentric locking mechanism, the other end of the handlebar vertical pipe is used for being horizontally inserted into a handlebar, the upper end of the shaft casing pipe is higher than the handlebar vertical pipe, a gland is arranged at the upper end of the shaft casing pipe to press the shaft casing pipe, and a screw is arranged in the gland and connected with a sunflower nut in a front fork so as to adjust the distance between the front fork and the headset. According to the rotatable bicycle handlebar vertical pipe assembly, the bicycle handlebar vertical pipe can be conveniently rotated, and the handlebar can be rotated to be parallel to a bicycle body, so that the width of the whole bicycle is greatly reduced, and the whole bicycle is conveniently stored and packaged.
Description
Technical field
The utility model relates to cycle arm, specifically, is a kind of rotatable cycle arm assembly.
Background technology
Existing bicycle, the vertical one end of handle and handlebar that bicycle handle bar is installed connect firmly, the other end and vertical tube of front fork screw fastening.There is a gland to push down vertical vertical upper end, in gland, have a screw to be connected with " heronsbill " nut in front fork, for regulating front fork bowls group gap.
Because handlebar is vertical with frame, the width of car load is exactly the length of handlebar, takes up space larger when depositing or packing.
Utility model content
Technical problem to be solved in the utility model is, a kind of simple in structure, easy to operate rotatable cycle arm assembly is provided, and handlebar be can rotate to and vehicle body parallel, thereby greatly reduces the width of car load, is convenient to deposit and pack.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rotatable cycle arm assembly, comprise the pipe spreader of the bowl group upper end that is arranged on bicycle head tube, one end is vertically locked on pipe spreader by eccentric locking mechanism, the handle that the other end inserts handlebar for level is vertical, described pipe spreader upper end exceeds vertical, there is a gland to push down pipe spreader in pipe spreader upper end, in gland, there is a screw to be connected with " heronsbill " nut in front fork, for regulating front fork and bowl group gap.
Described handle stands and pipe spreader cooperatively interacts, and there is anti-skidding straight burr groove at position.
Being provided with the hook with safety tong that prevents that the eccentric handle of eccentric locking mechanism from surprisingly opening on vertical.
Described pipe spreader is divided into two sections that are connected up and down, diameter with the epimere of anti-skidding straight burr groove is less than smooth hypomere diameter, make vertical one end be enclosed within on the epimere with anti-skidding straight burr groove, and the platform being formed by the epimere of pipe spreader, hypomere supports, on the epimere with anti-skidding straight burr groove, be provided with the elongated position-limited trough of level, the position relative with position-limited trough on vertical is being provided with and connecting spacing hole, limited screw one end enters position-limited trough by connecting spacing hole, limits standing in reference position mobile on pipe spreader by the radical length of position-limited trough.
The beneficial effects of the utility model are: can facilitate rotary bicycle vertical, handlebar be can rotate to and vehicle body parallel, thereby greatly reduce the width of car load, be convenient to deposit and pack.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-4, rotatable cycle arm assembly of the present utility model, comprise the pipe spreader 2 of bowl group 4 upper ends that are arranged on bicycle head tube 3, one end is vertically locked on pipe spreader 2 by eccentric locking mechanism 6, the handle that the other end inserts handlebar 14 for level stands 1, and described pipe spreader 2 upper ends exceed standing 1, have a gland 7 to push down pipe spreader 2 in pipe spreader 2 upper ends, in gland 7, there is a screw 8 to be connected with " heronsbill " nut 10 in front fork 9, for regulating front fork 9 and bowl group 4 gaps.
There is anti-skidding straight burr groove 11 at described handle vertical 1 and pipe spreader 2 position that cooperatively interacts.
On handle vertical 1, be provided with the unexpected hook with safety tong 12 of opening of eccentric handle 13 that prevents eccentric locking mechanism 6.
Described pipe spreader 2 is divided into two sections that are connected up and down, diameter with the epimere of anti-skidding straight burr groove 11 is less than smooth hypomere diameter, make vertical 1 one end be enclosed within on the epimere with anti-skidding straight burr groove 11, and by the epimere of pipe spreader, the platform 15 that hypomere forms supports, on the epimere with anti-skidding straight burr groove 11, be provided with the elongated position-limited trough 17 of level, the position relative with position-limited trough 17 on vertical 1 is being provided with and connecting spacing hole 16, limited screw one end enters position-limited trough 17 by connecting spacing hole 16, radical length by position-limited trough 17 limits the reference position moving on pipe spreader 2 vertical 1.
Specifically, handle of the present utility model vertical 1 is arranged on pipe spreader 2, and pipe spreader 2 is arranged on 3 bowls of group 4 upper ends of bicycle head tube.The breach 5 that has perforation on vertical 1, be locked on axle sleeve 2 by eccentric locking mechanism 6.Pipe spreader 2 upper ends slightly exceed standing 1, have a gland 7 to push down pipe spreader 2 in pipe spreader 2 upper ends, have a screw 8 to be connected with " heronsbill " nut 10 in front fork 9, for regulating front fork bowls group 4 gaps in gland.
Above-described embodiment is only for illustrating technological thought of the present utility model and feature, its object is to make those skilled in the art can understand content of the present utility model and implement according to this, can not only limit the scope of the claims of the present utility model with the present embodiment, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the scope of the claims of the present utility model.
