Description
Technical field
The utility model belongs to bicycle assembly parts technical field, particularly relates to a kind of cycle chain tensioner.
Background technology
In the ride of bicycle, change due to the spacing of trailing wheel and axis can produce the lax phenomenon of chain, especially more obvious for the bicycle above-mentioned chain relaxation that this kind of usage frequency of public bicycles is large, finally causing frequently dropping of cycle chain, bringing great inconvenience for riding.Fully take into account the lax situation of above-mentioned chain in the design of bicycle structure and provided a solution for it, bicycle rear wheel shaft is arranged in the chute of a transverse direction in the end of after cross member, by laterally regulating the tensioning of position realization to chain of rear axle gradually laterally.The very loaded down with trivial details effort of its operation of above-mentioned tension structure, and cannot tackle the problem at its root.Be developed tensioner apparatus thus, existing tensioner structurally generally comprises the track adjusting wheel of gear as chain of one or two and chain interoperation, tensioner arranges the screw rod and the nut that track adjusting wheel are carried out to position adjustments, above-mentioned chain tensioning device complex structure, install loaded down with trivial details, fault rate is high and maintenance maintenance inconvenient.
Utility model content
The utility model for solve in known technology the technical matters that exists and provide a kind of structure simple, be easy to installations, long service life, be easy to the cycle chain tensioner of maintenance.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: cycle chain tensioner comprises adapter plate, being provided with the anchor fitting for clamping bicycle after cross member, bottom it, being provided with tightening device cycle chain being carried out to tensioning at its top; Anchor fitting comprises the ambulatory splint of strap that fix with adapter plate, arc and arc, and a lateral edges of ambulatory splint is articulated and connected with the corresponding edge of strap, opposite side edge adopts bolt to be fixedly connected with the corresponding edge of strap; Tightening device comprise one end adopt tensioner axle install on a mounting board, the chain tray of strip shape, the front-end and back-end of chain tray all have curved profile, be equipped with integrated wing plate at the edge of chain tray madial wall and lateral wall, between wing plates on two sides, form the slideway of cycle chain; The lateral wall of adapter plate and chain tray is equipped with jack, between two jacks, is provided with torsion spring.
Advantage of the present utility model and good effect are: the utility model provides a kind of cycle chain tensioner of structure design advantages of simple, the anchor fitting that adapter plate top is made up of strap and ambulatory splint makes whole tensioner apparatus be installed to easily on bicycle after cross member, and dismounting is convenient.Compared with the tensioner of existing structure, adopt in the technical program and there is cambered way and the chain tray of flexible rotating replaces the track adjusting wheel of gear structure centered by tensioner axle, structure is more succinct, longer service life, not easily et out of order in long-term use procedure.Torsion spring provides chain tray to the elastic force of tensioned, without the need to carrying out adjustment in Long-Time Service process, stable and be easy to safeguard.Cycle chain operates in chute that chain tray is limited by wing plates on two sides and not easily deviates from, and reduce further fault rate, promotes the convenience of riding.This tensioner can increase the cornerite of flywheel and wheel disc, increases the reliability of cycle chain transmission.
Preferably: strap adopts multiple bolt to be fixedly connected with adapter plate.
Preferably: ambulatory splint is articulated and connected with the top of strap, bottom margin adopts bolt to be fixedly connected with.
Preferably: the width of chain tray lateral wall edge wing plate is greater than the width of madial wall edge wing plate.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 and Fig. 2, the utility model comprises adapter plate 4, being provided with the anchor fitting for clamping bicycle after cross member, bottom it, being provided with tightening device cycle chain being carried out to tensioning at its top.
Anchor fitting comprises, the strap 2 of arc fixing with adapter plate 4 and the ambulatory splint 1 of arc, and a lateral edges of ambulatory splint 1 is articulated and connected with the corresponding edge of strap 2, opposite side edge adopts bolt to be fixedly connected with the corresponding edge of strap 2.By carrying out dismounting to above-mentioned bolt, realize the open and close between ambulatory splint 1 and strap 2, bicycle after cross member is clamped between the two, complete this chain tensioning device in vehicle installation with it.
As shown in the drawing, in the present embodiment, strap 2 adopts multiple bolt to be fixedly connected with adapter plate 4; In order to promote the convenience that this tensioner apparatus is installed at vehicle with it, ambulatory splint 1 and the hinge connection of both straps 2 being arranged on top, the position be fixedly connected with being arranged on bottom.Like this, after unclamping the bolt of bottom, ambulatory splint 1 upwards rotating opening, can avoid the operation inconvenience brought with the component contact of below.But it is envisioned that above-mentioned hinge connection and the portion of being fixedly connected with are not confined to above-mentioned position.
Tightening device comprises one end and adopts tensioner axle 5 to be arranged on chain tray 6 on adapter plate 4, strip shape, and the front-end and back-end of chain tray 6 all have curved profile, avoid causing resistance to the operation of cycle chain.Be equipped with integrated wing plate at the edge of chain tray 6 madial wall and lateral wall, between wing plates on two sides, form the slideway of cycle chain.Cycle chain runs and can effectively avoid in the slideway of said structure, improves the stability of operation, reduces fault rate.In the present embodiment, the width that the width arranging chain tray 6 lateral wall edge wing plate is greater than madial wall edge wing plate chain can be avoided so further to deviate from laterally and chain to the wearing and tearing of adapter plate 4.
The lateral wall of adapter plate 4 and chain tray 6 is equipped with jack, and between two jacks, be provided with torsion spring 3, torsion spring 3 provides the tensile force of chain tray 6 pairs of cycle chains.Can ensure that under the effect of torsion spring 3 chain under any circumstance remains tensioning state, avoid because chain-loose falls the situation of chain.This tensioner can increase the cornerite of flywheel and wheel disc, increases the reliability of chain gear.
The experiment proved that, after this chain tensioning device is installed, effectively can reduce the loosening generation of chain, guarantee that cycle chain is non-maintaining in 3 years, reduce the maintenance load because chain-loose produces, substantially increase coefficient of avalability of vehicle, improve the convenience that user uses, be especially applicable to being applied to the higher bicycle of this kind of frequency of utilization of public lease bicycle.
