For understanding and approval further can be arranged structure, characteristic and the effect of the utility model, enumerate following preferred embodiment and conjunction with figs. the explanation as after.
See also Fig. 1 to shown in Figure 3, the utility model comprises:
One flower-drum 10 is provided with an axis hole 11 in this flower-drum 10, establish a tapped hole 111 at axis hole 11 inwalls.
One is connected the sleeve 20 of a side with flower-drum 10; These sleeve 20 1 sides are provided with one and have several equidistance arrangement ratchets 21 in ratchet wheel 22 on every side; Ratchet wheel 22 also has one and laterally one first is embedded groove 221 around the ratchet wheel 22; One spacing fin 222 is set in the ratchet wheel 22, and this ratchet 21 can be done the angular deflection of predetermined angle in ratchet wheel 22, and each ratchet 21 is also established one second and is embedded groove 211 relatively being embedded groove 221 positions at first of ratchet wheel 22; Have one first tooth portion 212, and one second tooth portion 213 at the front end of each ratchet 21, these sleeve 20 another opposite sides are made as a croze axle 23 and are sheathed on the gear disk (not drawing among the figure).
One places in the flower-drum 10 and the ratchet collar 30 that engages with ratchet wheel 22; These ratchet collar 30 inwalls are provided with the ratchet 31 that several equidistance are arranged; The ratchet 31 of the ratchet collar 30 can supply ratchet 21 pushing tows, has a limited wall 32 (as shown in Figure 5) in these ratchet collar 30 1 sides, to increase the side pressure of the ratchet collar 30; Can increase ratchet collar integral intensity; These ratchet collar 30 outsides have an outside thread 33, with solid with tapped hole 111 spiral shells of flower-drum 10, flower-drum 10 is engaged with the ratchet collar 30 be one.
One Hookean spring 40; This Hookean spring 40 is sheathed on first of ratchet wheel 22 and is embedded second of groove 221 and ratchet 21 and is embedded in the groove 211, makes ratchet 21 be arranged in ratchet wheel 22, has the position-limiting action that is difficult for dropping out; And these Hookean spring 40 1 ends have spacing section 41 of protrusion; Can be arranged in the spacing fin 222 of ratchet wheel 22 by spacing section 41 of Hookean spring 40, make Hookean spring 40 keep fixedly difficult drop-off, can supply the pushing tow start of ratchet 31 with the ratchet 21 of the ratchet collar 30.
Please continue to consult Fig. 1 to Fig. 3; Reach to cooperate and consult Fig. 4, utilize above-mentioned component groups to become the structure of the utility model, earlier several ratchets 21 are limited on the ratchet wheel 22 by Hookean spring 40 to shown in Figure 5; Make this ratchet 21 can in ratchet wheel 22, do the angular deflection of predetermined angle; And, make Hookean spring 40 keep fixedly difficult drop-off with spacing section 41 spacing fin 222 that is arranged in ratchet wheel 22, can supply the pushing tow start of ratchet 31 with the ratchet 21 of the ratchet collar 30.
Again the ratchet collar 30 is arranged in the flower-drum 10 with the mode of closely cooperating, supplies ratchet wheel 22 to engage again, but form the ratchet 31 of the ratchet 21 pushing tow ratchet collars 30.
When the bicycle pedal forward was trampled, gear disk drove sleeve 20 and rotates, and the ratchet 31 (like Fig. 3, shown in Figure 4) of the pushing tow ratchet collar 30 makes the ratchet collar 30 also drive flower-drum 10 and rotates thereupon ratchet 21 along with sleeve 20 rotations.
And bicycle pedal is oppositely trampled, or bicycle pedal is when motionless, and gear disk and sleeve 20 stop not rotate, and ratchet 21 is instead compressed by the ratchet 31 of the ratchet collar 30, make ratchet 21 toward the axle center bottoms, form the ratchet collar 30 and flower-drum 10 idling conditions.
In addition; The ratchet 21 of the utility model has the first tooth portion 212, and the second tooth portion 213; Like Fig. 3, shown in Figure 4, in the time of can trampling with the bicycle pedal forward, by the first tooth portion 212 of ratchet 21 or the ratchet 31 of the second tooth portion, the 213 promotion ratchet collars 30; Have automatically more orthofunction, and increase ratchet 21 and promote ratchets 31 reaction velocitys.
In addition; Because the ratchet 21 of the utility model has the first tooth portion 212 and the second tooth portion 213, and is as shown in Figure 6, it is more that the second tooth portion 213 of ratchet 21 can apply to the ratchet 31a number of teeth of ratchet collar 30a; The tooth pitch of ratchet 31a is shorter relatively; Can let the first tooth portion 212 and the second tooth portion 213 promote two ratchet 31a of ratchet collar 30a simultaneously, increasing the power that ratchet 21 promotes ratchet collar 30a transmissions, and the sleeve 20 that need not to change different ratchet wheels 22 can cooperate; Can save sleeve 20 costs of preparing different size, with human cost of saving replacing and saving replacing time.
In addition; The utility model also can be provided with an axial positioning hole 223 at the end face of ratchet wheel 22, lets spacing section 41 of Hookean spring 40 to be inserted in this positioning hole 223, also makes Hookean spring 40 keep fixedly difficult drop-off; Spacing in addition to ratchet 21, its advantage and above-mentioned constant.
The above explanation; Be merely the utility model preferred embodiments; Be intended to the characteristic of clear and definite the utility model, non-in order to limit the interest field of application, the equalization that those skilled in the art do according to the utility model changes; And the change known of those skilled in that art, must belong to the scope that the utility model is contained.
