Abstract
The utility model relates to a dismountable chain hood for the bicycle with a variable speed gear, comprising a curved type head part of the hood, matched with the radial periphery of a chain wheel, and a tail part of the hood, extending backward; the upper part is provided with a connection structure which can clamp the root part of the shift arm of the chain of the variable speed gear, and the tail part of the hood is provided with a connection machine which can be connected with the taper part of the shift arm.
Description
The utility model relates to a kind of bicycle chain.
Variable speed bicycle, the bicycle that particularly has sprocket speed changing device, portion is provided with change-speed box because of sprocket wheel, and the speed change moving arm will be stirred the oscillating type motion of chain during its speed change in the certain amplitude scope, and common bicycle chain is to be fixedly linked on the vehicle frame, can't adapt to this sprocket speed changing device that has sports type, therefore derailleur nearly all is not equipped with chain guard at present.Consequently often make troubles, as trousers, skirt are made dirty, even trousers angle or shirt rim are winched into sprocket wheel, damage trousers, skirt, also can therefore have an accident to the bicyclist.
The purpose of this utility model is to provide a kind of at the problems referred to above to adapt to the sports type chain puller, and can be with the movable chain guard of the synchronization-moving variable speed bicycle of its group chain movement.
The utility model activity chain is covered with curved face type capouch portion that an energy and sprocket wheel outer radial periphery adapt and the cover afterbody that extends back thereof, its top is provided with the draw bail that can be held on change-speed box chain moving arm root, and the cover afterbody is provided with the connection holes that can connect with this moving arm taper.Because the whole chain wheel cover only connects with movable parts chain moving arm in the change-speed box, therefore just can realize making same moved further, thereby reach the effect that can be all the time the top of chain and sprocket wheel be sheltered from the motion of group chain arm.Can solve derailleur thus the problem that is suitable for chain guard is installed.When chain guard has last aspect and two block surfaces of vertical side simultaneously, more smooth for the ease of making chain guard with dialling the motion of chain device, the block surface width of its vertical side with the block surface width that is narrower than the aspect for well.
Below structure of the present utility model is described, but scope of the present utility model is not limited only to this example with example shown in the drawings.
Fig. 1 constructional drawing of the present utility model
As shown in the figure, this derailleur activity chain is covered with band radian curved face type capouch portion 1 that an energy and sprocket wheel outer radial periphery adapt and the cover afterbody 3 that extends back thereof, its top is provided with a clamping plate type draw bail 2 that can be held on change-speed box chain moving arm root, and cover afterbody 3 is provided with the connection holes 4 that can connect with this moving arm taper.Chain guard has top and two block surfaces of vertical side, and wherein the width of the side block surface 5 of capouch is significantly smaller than the width of aspect 6 block surfaces on it.
Claims (2)
1, the movable chain guard of a kind of variable speed bicycle, it is characterized in that having curved face type capouch portion (1) that an energy and sprocket wheel outer radial periphery adapt and the cover afterbody (3) that extends back thereof, its top is provided with the draw bail (2) that can be held on change-speed box chain moving arm root, and the cover afterbody is provided with the connection holes (4) that can connect with this moving arm taper.
2, chain guard as claimed in claim 1 is characterized in that the block surface width of said curved face type capouch portion (1) vertical side (5) is narrower than the block surface width of aspect (6).
