Description
Technical field
This utility model relates to bicycle art, is specially a kind of bicycle scalable connected crank.
Background technology
Connected crank fixed by existing bicycle mainly two kinds of forms, and the first is that the stage casing of Z-shaped configuration is just arranged
The polygon such as hexagon or square is convex stupefied, utilizes convex stupefied corner angle fixed gear plate so that fluted disc does not offsets, but long
Time use friction the corner angle of regular hexagon or square can be made to become the most smooth, thus cannot fixed gear plate, the second
It is that the stage casing of Z-shaped configuration arranges cylindrical protrusions, fix stopper is set in cylindrical protrusions adjacent crank section, rely on fixing gear
Pin fixes fluted disc, uses middle fix stopper can bear the biggest torsion, so fix stopper is easy to fracture or comes off.
The crank arranged in pairs or groups in the market is all regular length, and some buyers require to take usually in accordance with external driver
Join and use same size, and so-called external driver, the most all based on western countries, on human geometry, west and east
The size difference of ethnic group is the biggest, therefore generally automobile friend is after purchasing car, the sport injury on health or discomfort all can occur, want to look for
State to the most comfortable is the most repeatedly reequiped, and represents when need not bicycle to others' OK range the most very
Little, obtain falling below the range of bicycle.
Utility model content
The purpose of this utility model is to provide a kind of bicycle scalable connected crank, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, this utility model following technical scheme of offer: a kind of bicycle scalable connected crank, bag
Including epimere, stage casing and hypomere, described epimere, stage casing and hypomere are welded into an entirety, and it is convex that side, described stage casing is provided with polygon
Platform, described epimere outer lower portion be provided with described stage casing be provided with polygon boss with the use of fix stopper, described polygon
Shape boss is adjacent with fix stopper, and one side adjacent with being provided with fix stopper outside described epimere is provided with fixed knob, described under
Duan Yu epimere is provided with the identical face of fixed knob and also is provided with fixed knob, is designed with adjustable stretching in described hypomere and epimere
Contracting bar.
Preferably, described polygon boss is positive six limit boss or positive four limit boss.
Preferably, described epimere, stage casing and hypomere are welded into a Z-shaped entirety.
Preferably, described expansion link head end is provided with the adjustment hole for regulation, and described expansion link end is provided with pedal and installs
Hole.
Preferably, head and the tail two ends in described stage casing are provided with screw thread.
Preferably, described epimere, stage casing, hypomere and expansion link are all stainless steel.
Compared with prior art, the beneficial effects of the utility model are: this utility model reasonable in design, user
Just, it is simple to promote, the structure design of expansion link, it is achieved that connected crank can regulate disjunctor bent according to the difference of people's height
The length of handle, and the consubstantiality design of polygon boss and fix stopper, reach dual fixed effect, substantially prolongs disjunctor bent
The service life of handle, and improve the safety coefficient of user.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of bicycle scalable connected crank, including
Epimere 1, stage casing 2 and hypomere 3, described epimere 1, stage casing 2 and hypomere 3 be welded into an entirety, and side, described stage casing 2 is provided with polygon
Shape boss 4, described epimere 1 outer lower portion be provided with described stage casing 2 be provided with polygon boss 4 with the use of fix stopper 5,
Described polygon boss 4 is adjacent with fix stopper 5, and one side adjacent with being provided with fix stopper 5 outside described epimere 1 is provided with fixing
Knob 6, described hypomere 3 also is provided with fixed knob 6 being provided with the identical face of fixed knob 6 with epimere 1, described hypomere 3 and epimere 1
Inside it is designed with adjustable expansion link 7.
Described polygon boss 4 is positive six limit boss or positive four limit boss, it is possible to make the effect of fixed gear plate more preferable, described
Epimere 1, stage casing 2 and hypomere 3 are welded into a Z-shaped entirety, and described expansion link 7 head end is provided with the adjustment hole 8 for regulation, institute
Stating expansion link 7 end and be provided with pedal installing hole 9, it is simple to the even regulation to connected crank length, head and the tail two ends, described stage casing 2 set
Having screw thread, described epimere 1, stage casing 2, hypomere 3 and expansion link 7 is all stainless steel, it is ensured that the service life of connected crank.
This utility model in use, when needing the length changing connected crank, can be by rotating epimere 1 and hypomere
