Abstract
The utility model relates to a guard for chains of the variable speed bicycle. The technique is characterized in that a chain cover which is covered above the chain of the bicycle and is fixedly connected with the guide plate of the speed variator of a chain wheel to form an adjustable chain cover; or a gap is arranged at the control shaft position of the guide plate which is corresponding to the chain cover; the chain cover is fixed to the frame to form a fixed chain cover. The utility model uses a small cover shell to protect the variable speed chain, which prevents trouser legs from being dirtied by oil.
Description
The variable speed bicycle that the utility model relates to protects chain apparatus, belongs to bicycle accessories.
Existing variable speed bicycle divides internal speed-changing and outer speed change, and in the variable speed bicycle, its constituent elements major part is exposed at appearance outside, because there is not chain guard, the lubricating oil in the time of by bike on the chain is easy to be stained with on the trousers angle, brings some troubles and worry to the rider.
The purpose of this utility model is: design a kind of chain guard to variable speed bicycle, it can protect the chain of sway with less case, and oiled trouser not.
The technical solution of the utility model is: a kind of variable speed bicycle protects chain apparatus, has chain, this chain passes through between the guide plate of sprocket transmission, be sleeved on the hinge wheel, it is characterized in that: chain guard is equipped with in this chain top, and the connecting bore of chain guard is fastened on the actuating spindle of sprocket transmission with guide plate.
The chain guard of present technique and guide plate can be one, are fastened on the sprocket transmission actuating spindle.
The chain guard of present technique can be at corresponding guide plate and actuating spindle junction gap to be arranged, and this chain guard is fixed on the vehicle frame.
The transformation chain wheel speed shifts one's position guide plate, when moving right, chain in the middle of the guide plate puts the many hinge wheels of the number of teeth, and when moving to left, this chain puts the few hinge wheel of the number of teeth, chain cooperates with the hinge wheel of the different numbers of teeth, the conversion transmission speed ratio, and realize bicycle shift.The chain guard of present technique is fixed together with guide plate or is coaxial with guide plate, and during speed change, chain and chain guard move in the same way with guide plate.This its advantage of portable chain guard is: volume is little, in light weight, aesthetic in appearance, again can effective isolation trousers angle and chain contact site, and make the trousers angle not be subjected to oil pollution.When the present technique chain guard is fixed on the vehicle frame, because guide plate and actuating spindle junction are positioned at the gap of chain guard, so fixedly chain guard does not influence the displacement of guide plate and chain.Therefore the less case of volume still can protect speed-changing chain and oiled trouser not effectively.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 protects the portable chain guard structural representation of chain apparatus for the utility model variable speed bicycle.
Fig. 2 protects the fixed type chain guard structural representation of chain apparatus for the utility model variable speed bicycle.
Fig. 3 protects the integral type chain guard structural representation of chain apparatus for the utility model variable speed bicycle.
