Abstract
The invention discloses an anti-separation bicycle transmission, which comprises a fixed bracket, wherein a detachable chain wheel is arranged at the bottom of the fixed bracket; a detachable antiskid device is arranged on each of the two sides of the chain wheel. According to the anti-separation bicycle transmission, wedge-shaped protective frames are arranged on the antiskid devices manufactured from nylon, so that the position of a chain can be effectively limited, the chain can be completely prevented from being separated from a rear small gear, and the reliability and the stability of the bicycle transmission are improved; the bicycle transmission is simple in structure, convenient to mount and high in practicability.
Description
Technical Field
The invention relates to a bicycle part, in particular to an anti-falling bicycle speed changing device.
Background
The bicycle speed variator is a common bicycle part and has the function of changing the speed of a bicycle by changing the matching of a chain and gear discs with different front and rear sizes. The rear pinion of the existing transmission is usually directly hung on a support, when the road condition is bumpy, and a user changes the speed, the chain can be loosened momentarily, and the chain can fall off from the rear pinion, so that the riding safety is affected.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides an anti-falling bicycle speed changing device.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides an anti-drop's bicycle speed change gear, anti-drop's bicycle speed change gear contain a fixed bolster, the bottom of fixed bolster be equipped with a detachable sprocket, the both sides of sprocket be equipped with a detachable antiskid unit respectively.
As a preferred embodiment of the present invention, the lower end of the fixing bracket is provided with a pair of mounting long holes, the anti-skid device is provided with a pair of fixing through holes and a wedge-shaped protection frame, and a pair of fixing screws respectively penetrate through the fixing through holes and the mounting long holes and are connected with a pair of fixing nuts.
As a preferred embodiment of the invention, the antiskid device is made of nylon.
The anti-falling bicycle speed changing device utilizes the anti-slipping device made of nylon, and the wedge-shaped protective frame is arranged on the anti-slipping device, so that the position of a chain can be effectively limited, the chain is thoroughly prevented from falling off from a rear pinion, the reliability and the stability of a bicycle speed changer are improved, the structure is simple, the installation is convenient, and the practicability is high.
