Description
Technical field
The utility model relates to a kind of crank groups, and in particular to seperated Quick Release crank group.
Background technique
Crank group can be largely used during the manufacture and use of bicycle, crank is attached shape with foot-operated
At the power device that a driving bicycle moves ahead, when bicycle sale is gone abroad, many bicycles need separately to pacify
Crank group, needs to carry out assembling again in external factory, causes the expense of the assembling of bicycle manufacturing enterprise, very much
Crank group on bicycle can not be dismantled quickly, and the effect of the group installation and dismantling disassembly of the crank group on bicycle is affected
Rate, also have part crank group structure be it is foot-operated be threaded with crank, in order to case facilitate do not fill when leaving the factory it is foot-operated
It is sold after being assembled again by professional factory after abroad, especially very inconvenient to online shopping and costly in this way, crank group is assembled not
Conveniently and structure is complicated, so that crank group safety is inadequate.
Summary of the invention
It can be realized fast quick-detach crank and foot-operated seperated Quick Release crank group the purpose of the utility model is to provide a kind of.
The technical solution of the utility model are as follows: seperated Quick Release crank group, including crank (1) and foot-operated (2), in crank (1)
On be provided with Quick Release hole, foot-operated (2) extend into Quick Release hole, are internally provided with spring (3) in song (1) handle, the upper end of spring (3)
It squeezes into bullet pin (4), bullet pin (4) is moved up and down in the drive of spring (3), is penetrated screw (5) in bullet pin (4), bullet pin (4) is in bullet
Spring (3) moves up under driving and blocks foot-operated (2) by protruding block, and the gap between foot-operated (2) and crank (1) is embedded in increasing
Strong set (6).
In described foot-operated (2) the laterally inserted crank (1), rides (2) and crank (1) is mutually flexibly connected.
The enhancing set (6) is the heat treatment set through Overheating Treatment and enhancing set (6) is set on the outside of crank (1)
It sets.
The screw (5), which moves inward or outward, is fixed or dismantles foot-operated (2).
The utility model has the advantages that: moved the upper and lower floating of pin by spring band, can allow crank and it is foot-operated between
It realizes disassembly and assembly, by the mutual cooperation of screw and bullet pin, realizes crank and foot-operated locking and disassembly, allow crank group
Disassembly and assembly is more efficient, reduces the cost of the assembling of enterprise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of the utility model.
In figure: 1 is crank, 2 be it is foot-operated, 3 be spring, and 4 be bullet pin, and 5 be screw, and 6 be enhancing set.
Specific embodiment
Seperated Quick Release crank group, including crank (1) and foot-operated (2), are provided with Quick Release hole on crank (1), foot-operated (2) prolong
It protrudes into Quick Release hole, is internally provided with spring (3) in song (1) handle, the upper end of spring (3) is squeezed into bullet pin (4), and bullet pin (4) is in bullet
The drive of spring (3) moves up and down, and penetrates screw (5) in bullet pin (4), and bullet pin (4) moves up dependence in the case where spring (3) drive
Protruding block blocks foot-operated (2), and the gap between foot-operated (2) and crank (1) is embedded in enhancing set (6).
In described foot-operated (2) the laterally inserted crank (1), rides (2) and crank (1) is mutually flexibly connected.
The enhancing set (6) is the heat treatment set through Overheating Treatment and enhancing set (6) is set on the outside of crank (1)
It sets.
The screw (5), which moves inward or outward, is fixed or dismantles foot-operated (2).
It is embedded into the cavity in crank (1) in the spring that crank (1) does not have, is configured along the cavity in crank (1),
Spring (3) carries out upper and lower stretch in crank (1) cavity.
In spring (3) upper end the bullet pin (4) of setting with screw (5) is mutual is engaged, screw (5) is engaged and extends into bullet pin
It is capable of fixing and rides, can be unclamped with elasticity when screw (5) extends outwardly, so that foot-operated (2) can be detached from crank.
Claims (4)
1. seperated Quick Release crank group, including crank (1) and ride (2), it is characterised in that: it is provided with Quick Release hole on crank (1),
Foot-operated (2) extend into Quick Release hole, and in crank (1), handle is internally provided with spring (3), and bullet pin (4) are squeezed into the upper end of spring (3),
