Abstract
The utility model discloses a chain ware is led to bicycle, include connecting portion, buffering portion and lead chain portion, the buckle spare of connecting portion for having the U -shaped groove, buffering portion includes universal joint and spring, leading chain portion and including sprocket and U -shaped support, universal joint connects between buckle spare and U -shaped support, the sprocket setting on the U -shaped support, spring coupling between buckle spare and U -shaped support, and be located universal joint's both sides, the utility model has the advantages of being simple in structure and convenient in operation, can effectively reduce to lead the chain ware at the resistance of leading the chain in -process, avoids the chain shake.
Description
Technical field
This utility model belongs to technical field of bicycles, is specifically related to a kind of bicycle fairleader.
Background technology
Fairleader is used on mountain bike, and it dials the chain shake that guide arm causes after can limiting under severe jolt, thus reducing that chain beats car and frame causes the abrasion of vehicle frame and chain and falls the occurrence probability of chain；Although and existing fairleader simple structure but price is high, guide chain portion is owing to adopting plastic material, easy to wear and resistance is big；What the buffer part of some fairleaders adopted is material is softer plastics, when this softer plastics deform upon, has a kind of to the elastic force returned, and when carrying out the most high-grade or deep low gear speed change, chain can become staggered X-shaped；At this moment, make fairleader sidepiece lean against on chain, chain can be caused certain abrasion；Then need when the degree of wear is excessive to change chain.
Utility model content
The purpose of this utility model is for problems of the prior art, it is provided that a kind of simple and practical, safe and reliable bicycle fairleader；The problems such as existing fairleader is easy to wear, resistance is big can be overcome.
The technical solution adopted in the utility model is for achieving the above object:
A kind of bicycle fairleader, including connecting portion, buffer part and guide chain portion, described connecting portion is the fastener with U-lag, described buffer part includes universal joint and spring, described guide chain portion includes sprocket wheel and U-bracket, universal joint is connected between fastener and U-bracket, and sprocket wheel is arranged on U-bracket, and spring is connected between fastener and U-bracket and is positioned at the both sides of universal joint；
Further, the sidewall of described fastener and bottom are provided with draw-in groove；
Further, the material of described fastener is aluminium alloy；
Further, described universal joint is single-unit formula universal joint.
The beneficial effects of the utility model are:
This utility model is by the effect of single-unit formula universal joint and spring, the necessary deformation of buffer chain；Adopt the fit system of sprocket wheel tension chain to restrain chain shake, the fairleader resistance to chain can be effectively reduced simultaneously, also can avoid producing between chain and miscellaneous part friction；Fastener aluminium alloy, light weight, fastener arranges draw-in groove and is easy to the fixing of fairleader；Adopting single-unit formula universal joint, it is easy to assembly, structure is simplified.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model together with embodiment of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the schematic side view of Fig. 1.
In conjunction with accompanying drawing, in this utility model embodiment, accompanying drawing labelling is as follows:
1-fastener；2-universal joint；3-spring；4-sprocket wheel；5-U shape support；6-draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of utility model is illustrated:
As illustrated in fig. 1 and 2, a kind of bicycle fairleader, including connecting portion, buffer part and guide chain portion, described connecting portion is the fastener 1 with U-lag, described buffer part includes universal joint 2 and spring 3, and described guide chain portion includes sprocket wheel 4 and U-bracket 5, and universal joint 2 is connected between fastener 1 and U-bracket 5, sprocket wheel 4 is arranged on U-bracket 5, and spring 3 is connected between fastener 1 and U-bracket 5 and is positioned at the both sides of universal joint 2；Sidewall and the bottom of described fastener 1 are provided with draw-in groove 6；The material of described fastener 1 is aluminium alloy；Described universal joint 2 is single-unit formula universal joint.
In this utility model, the back vent of fastener 1 with bicycle is fixed by available bandage, and the draw-in groove 6 that fastener 1 is arranged is beneficial to the fixing of fastener 1；Sprocket wheel 4 is installed on U-bracket 5 by chain after U-bracket 5 again；Sprocket wheel 4 can by chain strain, so can prevent the shake of chain, the spring in universal joint 2 both sides is in extended state, when with the compound action of chain under can ensure that the balance of U-bracket 5 and universal joint 2 and have cushioning effect concurrently.
Last it is noted that the foregoing is only the preferred embodiment of utility model, it is not limited to utility model, although utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.Within all spirit in utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within the protection domain of utility model.
