Abstract
The invention discloses 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, have a screw to be connected with " heronsbill " nut in front fork, for regulating front fork and bowl group gap. The present invention can facilitate rotary bicycle vertical, handlebar be can rotate to and vehicle body parallel, thereby greatly reduces the width of car load, is convenient to deposit and pack.
Description
Technical field
The present invention 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 front fork standEffective screw fastening. There is a gland to push down vertical vertical upper end, in gland, have a screw and front fork interior " tooSun flower " nut connection, for regulating front fork bowls group gap.
Because handlebar is vertical with frame, the width of car load is exactly the length of handlebar, when depositing or packingTake up space larger.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of simple in structure, easy to operate rotatableCycle arm assembly, handlebar be can rotate to and vehicle body parallel, thereby greatly reduces the width of car load,Be convenient to deposit and pack.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of voluntarily rotatableHandlebar founds assembly, comprises the pipe spreader of the bowl group upper end that is arranged on bicycle head tube, and eccentric lock is passed through in one endTight mechanism is vertically locked on pipe spreader, and the handle that the other end inserts handlebar for level is vertical, described pipe spreaderUpper end exceeds vertical, has a gland to push down pipe spreader in pipe spreader upper end, has a screw and front fork in glandInterior " heronsbill " nut connects, for regulating front fork and a 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 safety door hook that prevents that the eccentric handle of eccentric locking mechanism from surprisingly opening on vertical.
Described pipe spreader is divided into up and down two sections that are connected, with the diameter of the epimere of anti-skidding straight burr groove than smoothHypomere diameter little, make vertical one end be enclosed within on the epimere with anti-skidding straight burr groove, and upper by pipe spreaderThe platform that section, hypomere form supports, and is provided with the elongated limit of level on the epimere with anti-skidding straight burr groovePosition groove, is being provided with perforation spacing hole the position relative with stopper slot on vertical, and limited screw one end is passed throughConnect spacing hole and enter stopper slot, the radical length by stopper slot limits standing on pipe spreader mobileOriginal position.
The invention has the beneficial effects as follows: can facilitate rotary bicycle vertical, handlebar be can rotate to and vehicle bodyParallel, thus greatly reduce the width of car load, be convenient to deposit and pack.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As Figure 1-4, rotatable cycle arm assembly of the present invention, comprises and is arranged on bicycleThe pipe spreader 2 of bowl group 4 upper ends of head tube 3, one end is vertically locked at axle sleeve by eccentric locking mechanism 6On pipe 2, the handle that the other end inserts handlebar 14 for level stands 1, and described pipe spreader 2 upper ends exceed vertical1, there is a gland 7 to push down pipe spreader 2 in pipe spreader 2 upper ends, in gland 7, there is a screw 8 and front fork 9Interior " heronsbill " nut 10 connects, 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 safety door hook of opening of eccentric handle 13 that prevents eccentric locking mechanism 612。
Described pipe spreader 2 is divided into up and down two sections that are connected, with the diameter ratio of the epimere of anti-skidding straight burr groove 11Smooth hypomere diameter is little, makes vertical 1 one end be enclosed within on the epimere with anti-skidding straight burr groove 11, and by axleThe epimere of sleeve pipe, the platform 15 that hypomere forms support, and on the epimere with anti-skidding straight burr groove 11, are provided withThe elongated stopper slot 17 of level, is being provided with the position relative with stopper slot 17 on vertical 1 to connect limitHole 16, position, limited screw one end enters stopper slot 17 by connecting spacing hole 16, by stopper slot 17Radical length limit vertical 1 on pipe spreader 2 a mobile original position.
Specifically, handle of the present invention vertical 1 is arranged on pipe spreader 2, and pipe spreader 2 is arranged on bicycle3 bowls of group 4 upper ends of head tube. The breach 5 that has perforation on vertical 1, lock by eccentric locking mechanism 6On axle sleeve 2. Pipe spreader 2 upper ends slightly exceed standing 1, have a gland 7 to push down in pipe spreader 2 upper endsPipe spreader 2, has a screw 8 to be connected with " heronsbill " nut 10 in front fork 9, for regulating in glandFront fork bowls group 4 gaps.
Above-described embodiment is only for illustrating technological thought of the present invention and feature, and its object is to makeThose skilled in the art can understand content of the present invention and implement according to this, can not be only with the present embodimentLimit the scope of the claims of the present invention, equal variation or modification that all disclosed spirit is done,Still drop in the scope of the claims of the present invention.
