Yet the chain cover 11 of this kind form can only be applicable to the installation combination on the vehicle frame of same wheelbase, and can't be applicable to the bicycle installation of various different wheelbases, for this reason, as China Taiwan application No. 92201221 " chain cover Telescopic adjustment structure improvement" new patent, which mainly guides and combines a telescopic section with a joint hole in the rear section of a chain cover, and the chain cover can be slid to adjust the length of the telescopic section embedded by the rear section sliding group to adapt to each When installed on a frame of different sizes and specifications, the telescopic section can be extended arbitrarily against the rear fork rod of the frame and locked with a combination piece
[0004] However, although this type of chain cover can be applied to vehicle frames with different wheelbases, it is not suitable for chain plates of different sizes, which highlights the defect of poor applicability. For example, the chain plate of road vehicles and mountain climbing off-road vehicles The sizes are different, in order to cope with the different sizes of the two chain discs, it is necessary to purchase different sizes of chain covers

The invention discloses a chain cover structure of a bicycle, aiming to solve the problem that the chain plates with different dimensions cannot be fit since the radian of the existing chain cover cannot be adjusted. The chain cover structure provided by the invention is suitable for being assembled in a bicycle rack to cover a chain and a chain plate, and consists of a fixing unit, a transfer unit, a chain cover element and a chain cover unit, wherein the chain cover element is used for covering the chain plate and the chain in the chain plate. The chain cover element is designed into a structure shape of which the radian dimension is capable of being adjusted, thus, the chain cover structure provided by the invention is suitable for the chain plates with different dimensions, and the applicability of the chain cover is improved.
Description
technical field [0001] The invention relates to the bicycle field, in particular to a bicycle chain cover structure. Background technique [0002] For safety considerations, the bicycle will be equipped with a chain cover above the corresponding chain. The chain cover can prevent the rider from accidentally touching it while riding the bicycle, avoiding the danger of trousers getting involved, and preventing the trousers from being dirty. [0003] Such as figure 1 As shown, the combination of the chain cover 11 and the bicycle 12 is generally to combine one end of the chain cover 11 on the crank main shaft 121, and at the same time form a protrusion 123 at the rear fork 122 of the bicycle 12, so that the other end of the chain cover 11 is combined on the crank shaft 121. bump 123 . Yet the chain cover 11 of this kind form can only be applicable to the installation combination on the vehicle frame of same wheelbase, and can't be applicable to the bicycle installation of var...
