In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
The utility model is further described in face.
Embodiment 1
Referring to Figure 1 to shown in 7, the first embodiment that chain leads back to structure automatically is fallen for the utility model bicycle, in Fig. 1
Show that the bicycle of the present embodiment falls chain and leads back to structure automatically to being in 5, including a crank 10, a fluted disc 20, a block 30 and
One guiding block 40.Wherein:
The lateral surface of one end of crank 10 is combined with a pedal 11.
Fluted disc 20 is incorporated on the medial surface for being fixed on 10 other end of crank using several fluted disc bolts 21, makes fluted disc 20
It can be driven and rotate by crank 10, on fluted disc 20 and being arranged with a chain 22.
Its screw lock is fixed on the other end of crank 10 using several block bolts 31 by block 30, makes block 30 and fluted disc
The groove 32 on the circumferential surface that one is located at 10 other end of crank is formed between 20, groove 32 is available in when falling chain and keeps off chain 22 in song
On the other end of handle 10, to prevent chain 22 from dropping to the lateral surface of crank 10.The circumferential surface of block 30 be formed with an ecto-entad by
Progressively lower oblique guiding incline 33 can further promote the effect for stopping the chain 22.In the present invention, groove 32 also can directly be set
In on the circumferential surface of block 30, this is the simple change of above structure, this is no longer separately repeated here.
Its screw lock is fixed on the medial surface of 10 centre of crank by guiding block 40 using several guiding block bolts 41, guiding
The gap for maintaining the side chain piece for chain 22 to pass through between the lower part and fluted disc 20 of block 40, top are then higher than the outer of fluted disc 20
Circumferential surface, and there is a guiding cambered surface 42, the cambered surface of guiding cambered surface 42 is to be gradually reduced from the front to the back, when guiding block 40 is by crank 10
When bringing up to a height, chain 22 then can be slid downwards along guiding cambered surface 42 by the upside of lifting to fluted disc 20 and
It is arranged on the sprocket of fluted disc 20 and is formed the state of cochain.
As shown in Fig. 4,5, when bicycle falls chain, chain 22 can be blocked between block 30 and fluted disc 20 and be formed
Groove 32 among.
As shown in Fig. 6,7, when the pedal 11 for continuing to step on other side crank 10 when falling chain makes 10 up time of crank
When needle rotates, then the guiding block 40 for being incorporated into the inside of crank 10 will be shifted up with the rotation of crank 10, and then by chain
Lifting makes chain 22 slide and be arranged in the sprocket of fluted disc 20 downwards along guiding cambered surface 42 to item 22 to the top of fluted disc 20 upwards
State that is upper and forming auomatic fixing chain.
Bicycle provided by the utility model falls chain and leads back to structure automatically, be in the situation for falling chain, can first benefit
Block chain 22 with block 30, then using continue to step on pedal 11 make guiding block 40 by chain 22 upwards lifting to fluted disc 20
Top, make chain 22 along guiding cambered surface 42 downwards slide and auomatic fixing chain, subtract suddenly when so can avoid falling chain
Speed stops the danger such as caused overtaking collision, and is even more to be not necessarily to manual cochain of getting off, and can greatly improve the convenience ridden,
It is especially even more that can therefore save a large amount of cochain time, and games results can be promoted in match.
