Description
Technical field
The present invention relates to a kind of cranks, and in particular to fast folding integral type crank.
Background technology
It needs to use crank when the installation of bicycle, but what the enterprise of many exportation abroads assembled in crank
When need to be assembled again, the mode of such crank assembling needs the expense of the payment assembling of enterprise again so that song
The manufacturing cost of handle manufacturing enterprise rises, and the assembling again of crank needs to spend a large amount of money of enterprise, leads to crank production enterprise
The cost of the production and transportation of industry increases.
Invention content
The object of the present invention is to provide a kind of reasonable for structure, fast folding integral type cranks of fast folding.
The technical scheme is that：Fast folding integral type crank, is provided with crank, Quick Release is provided on crank
Set is provided with circular hole on Quick Release set, is connected with Quick Release crank in the inside thread of Quick Release set, is provided on Quick Release crank fast
It tears hole open, Quick Release spring is embedded in Quick Release hole, fast bomb disposal pin is connected in the upper end of Quick Release spring.
The crank both ends are connected with Pedal connection department part, and Pedal connection department part is borehole structure and is arranged in circular hole
There is connection screw thread.
Boss is provided in the middle part of the crank, the boss is hexagonal structure.
The Quick Release set is rotated by inside thread, rotates to fast bomb disposal pin at fast bomb disposal pin and Quick Release is passed through to cover circular hole.
The inner wall of the Quick Release set is provided with wearing layer, and the wearing layer is made of wear-resistant material, wear-resistant material packet
It includes：La：0.0024~0.0065%, Cu：1.50~4.50%, Cr：5.0~6.5%, Mo：0.0020~0.007%, Ti：6.5~
8.5%。
Wear-resistant material further comprises：La：0.003~0.0055%, Cu：2.50~3.50%, Cr：5.0~6.2%, Mo：
0.003~0.007%, Ti：6.7~8.3%.
Wear-resistant material further comprises：La：0.004~0.0045%, Cu：2.9~3.50%, Cr：5.5~6.2%, Mo：
0.0047~0.007%, Ti：7.1~8.3%.
It is an advantage of the invention that：The rotation covered by Quick Release, when the upper end in rotating knife Quick Release hole, in Quick Release hole
Fast bomb disposal pin pops up, and fast bomb disposal pin enters in the circular hole on Quick Release set when pop-up, plays and fixes crank
Effect, be capable of the effect of the fast folding of lift crank in this way, need not carry out crank into assembling, reduce crank assembling
Expense, make the assembling of crank more efficient, increase wear-resistant coating can allow Quick Release set inside wear-resisting property optimization.
