Abstract
The utility model discloses a bicycle chain wheel which comprises a chain wheel body, chain teeth on the chain wheel body and a hub in the chain wheel body. A cylindrical through groove is formed in the hub, and a pocking bar is arranged in the through groove through a rotor. The poking bar is detachably connected with the rotor, and the rotor is detachably connected with the chain wheel body. The poking bar is identical with the through groove in terms of length, and the poking bar is cylindrical and identical with the through groove in terms of shape. A stretchy type design structure is adopted in the poking bar, a small LED lamp is arranged in one end of the poking bar, and an oil filling pen stored with lubricating oil is arranged on the other end of the poking bar. According to the bicycle chain wheel, when a user rides at night, if the user encounter the situation that the chain falls off, the poking bar can be taken off, the poking bar and the LED lamp and a hook portion on the poking bar are used for facilitating installing of the chain on the chain wheel body at night, and the bicycle chain wheel can be filled with oil in traveling. The bicycle chain wheel is simple in structure and convenient and fast to use.
Description
Technical field
The utility model relates to a kind of bicycle chainwheel, belongs to bicycle accessories field.
Background technology
Bicycle, as a kind of economy, environmental protection, the vehicle easily, occupies sizable proportion in daily life, especially in middle school student, occupies larger ratio.But bicycle tends to run into the situation of chain-taking when riding, particularly at night, if fallen chain, due to light difference with there is no the condition of instrument, be difficult to chain playback, often allow the user be very headache, therefore,, for existing technology, also need further improvement.
Summary of the invention
Technical problem to be solved in the utility model is easily to come off for solving cycle chain of the prior art, the defect that cannot easily chain be assembled up when de-chain, and then provide a kind of utilization to stir bar and LED lamp and the hook portion of stirring on bar can install to chain on sprocket wheel easily at night, also can be bicycle chainwheel oiling on the road, simple in structure, bicycle chainwheel conveniently.
The utility model is achieved through the following technical solutions: a kind of bicycle chainwheel, comprise sprocket on sprocket wheel and sprocket wheel and the wheel hub in sprocket wheel, described wheel hub is provided with a cylindrical groove, in described groove, by a rotor, be provided with and stir bar, described stirring between bar and rotor, rotor and sprocket wheel is detachable connection, describedly stir bar and groove is equal in length, described in to stir bar be the cylindrical shape that shape is identical with groove, described in stir the telescopic project organization of strip adoption.
As preferred technical scheme, described in stir bar one end and be built-in with compact LED lamp, the other end is the oiling pen of depositing lubricating oil.
As preferred technical scheme, described in stir bar one end oiling nib portion be provided with a hook portion, chain can be triggered in use, facilitate the installation of chain.
The beneficial effects of the utility model are: sprocket wheel of the present utility model, when riding night, user is as run into the situation of chain-taking, can take off stirring bar, bar is stirred in utilization and LED lamp and the hook portion of stirring on bar can install to chain on sprocket wheel easily at night, also can be bicycle chainwheel oiling on the road, simple in structure, convenient and swift.
