Abstract
The utility model relates to the technical field of the food processing equipment, in particular to a bicycle chain wheel. The bicycle chain wheel comprises a chain wheel body, wherein two end surfaces of the chain wheel body are both provided with oval auxiliary chain wheel blocks; an anti-falling groove is arranged between each auxiliary chain wheel block and the chain wheel body; the outer end of each auxiliary chain wheel block is provided with a chain installation spacing baffle. According to the bicycle chain wheel disclosed by the utility model, two end surfaces of the chain wheel body are both provided with detachable auxiliary chain wheel blocks, the anti-falling groove is arranged between each auxiliary chain wheel block and the chain wheel body, the outer end of each auxiliary chain wheel block is provided with the chain installation spacing baffle, so that the chain is arranged on the auxiliary chain wheel blocks by the chain installation spacing baffle when the chain is arranged, and the chain is moved onto the chain wheel body by the anti-falling groove. The device has a simple structure, and the chain can be effectively prevented from falling.
Description
Technical field
The utility model relates to bicycle equipment technical field, particularly a kind of bicycle chainwheel.
Background technology
At present, the no-float of bicycle chainwheel of the prior art and chain, although have anti-fall-off device for the driving chain, but complex structure, installs difficulty, and still there will be to fall the phenomenon of chain, pawn after chain, owing to there is no suitable instrument, therefore can cause the installation trouble of chain.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides one can effectively prevent chain, bicycle chainwheel simple in structure.
For achieving the above object, the utility model is by the following technical solutions: a kind of bicycle chainwheel, comprise sprocket body, the both ends of the surface of described sprocket body are equipped with the auxiliary sprocket block of ovalize, between auxiliary sprocket block and sprocket body, be provided with anticreep groove, auxiliary sprocket block outer end is provided with dress chain postive stop baffle.
Wherein, the front end face middle part of described sprocket body is connected with auxiliary sprocket block to bottom detouchable, and the aft end face middle part of sprocket body is connected with auxiliary sprocket block to top detouchable.
The utility model beneficial effect is: the utility model comprises sprocket body, and the both ends of the surface of described sprocket body are equipped with the auxiliary sprocket block of ovalize, between auxiliary sprocket block and sprocket body, is provided with anticreep groove, and auxiliary sprocket block outer end is provided with dress chain postive stop baffle; The utility model is by arranging the auxiliary sprocket block of detouchable in sprocket body both ends of the surface, and between auxiliary sprocket block and sprocket body, be provided with anticreep groove, auxiliary sprocket block outer end is provided with dress chain postive stop baffle, in the time of device chain, by dress chain postive stop baffle by chain device on auxiliary sprocket block, and by anticreep groove, chain is moved in sprocket body, this is simple in structure, can effectively prevent chain.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
reference numeral1---sprocket body 2---assisted sprocket block
3---anticreep groove 4---dress chain postive stop baffle.
The specific embodiment
With embodiment, the utility model is described in further detail below, is not practical range of the present utility model is limited to this.
As shown in Figure 1, a kind of bicycle chainwheel, comprises sprocket body 1, and the both ends of the surface of described sprocket body 1 are equipped with the auxiliary sprocket block 2 of ovalize, between auxiliary sprocket block 2 and sprocket body 1, be provided with anticreep groove 3, auxiliary sprocket block 2 outer ends are provided with dress chain postive stop baffle 4, the utility model is by arranging the auxiliary sprocket block 2 of detouchable in sprocket body 1 both ends of the surface, and be provided with anticreep groove 3 between auxiliary sprocket block 2 and sprocket body 1, auxiliary sprocket block 2 outer ends are provided with dress chain postive stop baffle 4, in the time of device chain, by dress chain postive stop baffle 4 by chain device on auxiliary sprocket block 2, and by anticreep groove 3, chain is moved in sprocket body 1, this is simple in structure, can effectively prevent chain, described dress chain postive stop baffle 4 both can be convenient to the installation of chain, can prevent that again chain from dropping out, the front end face middle part of described sprocket body 1 is connected with auxiliary sprocket block 2 to bottom detouchable, the aft end face middle part of sprocket body 1 is connected with auxiliary sprocket block 2 to top detouchable, the utility model separates 2 one-tenth first halves of described auxiliary sprocket block and lower part, sprocket body 1 is in the time rotating like this, the auxiliary sprocket block 2 of the first half and lower part influences each other, can play and prevent that chain from dropping.
