Abstract
The utility model relates to a cover chain driving device guide plate for speed-change bicycles, which solves the problems that a plurality of the existing bicycles can not be provided with chain covers and the assembled chain covers are unstable or uncoordinated. The structure is characterized in that both sides of the improved guide plate are provided with the chain cover 1 of a chain and a dental basin cover 2 which is directly used as a chain cover to reduce the machinery abrasion of the chain because of dust attachment and to avoid troubles of oil stain of the chain and a dental basin for bicyclists, on the basis of the front chain driving device guide plate 3 for the speed-change bicycle. The utility model has simple structure design and easy use and assembly, and is suitable for the existing various speed-change bicycles to assemble and use.
Description
The utility model relates to a kind of variable speed bicycle cover chain driving device guide plate.
Traditional variable speed bicycle does not have chain guard, makes chain adhere to dust easily, has quickened chain mechanical wear.Simultaneously because the greasy dirt on chain and the large toothed disk because of lacking protective device, often brings many worries to the rider.In recent years, though also there is the variable speed bicycle chain guard to come out, owing to the continuous remodeling of variable speed bicycle vehicle frame, chain occurred and covered on the not enough coordination of variable speed bicycle assembling, the part variable speed bicycle can not assemble problems such as chain guard and installation chain guard instability.The existence of the problems referred to above has brought inconvenience for the variable speed bicycle user.
The purpose of this utility model is to provide a kind of variable speed bicycle cover chain driving device guide plate simple in structure, easy to install, can be used as the chain chain guard.
The utility model is on existing variable speed bicycle front chain shifter guide plate (dotted portion in referring to accompanying drawing) architecture basics, improve dialling chain device guide plate, the characteristics of dialling the connected device guide plate after the improvement are to be provided with chain chain guard 1 and chain wheel cover 3 in variable speed bicycle front chain shifter guide plate 3 both sides.Above-mentioned chain guard and chain wheel cover and front chain shifter guide plate can weld makes one, also can adopt the direct punching press of pressure forming mode to make one.
The utility model structure design is simple, easy to install, is suitable for existing all kinds of variable speed bicycles and uses.This guide plate had both alleviated the chain dust and had adhered to and mechanical wear because of its both sides are provided with chain chain guard and chain wheel cover, can prevent again that simultaneously the greasy dirt on chain and the large toothed disk from making troubles to the rider.
Introduce the utility model specific embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model perspective view.
In the present embodiment, variable speed bicycle cover chain driving device guide plate centering guide 3 extends to both sides, and wherein a side is a chain chain guard 1, and opposite side is a chain wheel cover 2, and guide plate 3, chain guard 1 and chain wheel cover 2 adopt impact style to make one, assemble with group chain device.
