Description

A kind of power-saving pedal for bicycle mechanism

Technical field

The utility model relates to a kind of bicycle, specifically a kind of power-saving pedal for bicycle mechanism.

Background technique

Transmission mode traditional at present includes: foot-operated crank, flywheel, chain, sprocket wheel and the axis for installing sprocket wheel；By left and right Two foot pedals drive central axis and then rotate with movable sprocket, are advanced by the chain drive bicycle between sprocket wheel and flywheel 's；The distance of axis of two foot pedals of traditional transmission mode to sprocket wheel is fixed, that is to say, that the length of crank is solid Fixed, according to mechanics principle, the laborsaving crank that must be lengthened crank and ride is realized, since Human Height and bicycle size limit System, crank length is too long or too short do not utilize is ridden, too short expense, and the too long foot-operated track that rotates a circle is too long, expends the time Extend, can not normal speed ride.

Someone designs a Telescopic crank track type bicycle, such as notification number are as follows: 202213687 U of CN is disclosed thus A kind of Telescopic crank track type bicycle is fixed including vehicle frame, the front wheels and rear wheels being mounted on the vehicle frame, by axis Sprocket wheel on vehicle frame, the flywheel ridden, be mounted on the rear-wheel positioned at the vehicle frame two sides, the sprocket wheel fly with described Wheel passes through chain drive；Circuit orbit there are two being fixedly mounted in the vehicle frame two sides, the both ends of the axis are located at institute State the eccentric position in circuit orbit；It is respectively fixed with a bearing holder (housing, cover) at the both ends of the axis, in the bearing holder (housing, cover) respectively It is arranged a telescoping crank that can be stretched along the bearing holder (housing, cover), one end of the telescoping crank is rotatably mounted to ipsilateral with it The circuit orbit on；It is described foot-operated to be fixed on the telescoping crank and be located on one end that the circuit orbit connects.

Above-mentioned this structure is cooperated using bearing holder (housing, cover) and telescoping crank, and this structure is not reasonable, telescopic rod when use It is easy the card bottom of s trouser leg, has some potential safety problems when riding, while this structural reliability is also undesirable.

Utility model content

It the purpose of this utility model is to provide a kind of power-saving pedal for bicycle mechanism, is changed to existing structure Into, clamping rings is installed in the two sides of bicycle middle shaft, the slip ring coaxial with fixed ring is set on the inside of clamping rings, slip ring Central axis is located at the front side of axis, is fixed on the outside of slip ring foot-operated, and ring is sliding to pass through telescopic arm connection between axis；This reality Has the characteristics that structurally reasonable, easy for installation, good reliability compared with the existing technology with novel.

Following technical scheme is used to achieve the above object:

A kind of power-saving pedal for bicycle mechanism, including vehicle frame, axis, flywheel, chain, sprocket wheel and foot-operated, it is characterised in that: The left and right sides of the vehicle frame is also fixed with clamping rings, and the axis is in clamping rings, and clamping rings Slip ring is arranged in clamping rings inner edge in biased forward of the center relative to axis, and slip ring and clamping rings are coaxially disposed and can be with Clamping rings is that bracket rotates freely in clamping rings, is connected between the slip ring and the end of axis by telescopic arm, Telescopic arm one end is fixed on the end of axis, the other end and is hinged on slip ring；The foot-operated shaft is connected in slip ring Outside.

Ball or roller are set between the slip ring outer rim and clamping rings inner edge.

The foot-operated shaft and the close hinged place with telescopic arm in slip ring junction.

The pivot that the foot-operated shaft is connect as telescopic arm with slip ring.

Connecting rod is also set up between the clamping rings of the vehicle frame two sides.

Connecting rod is connected at the outer rim of two clamping rings lower parts or bottom.

Connecting rod is arranged in parallel with axis.

The clamping rings, which corresponds to open up at the position of vehicle frame, sets screw hole, and clamping rings is fixed by screws in vehicle frame On.

The utility model is disposed relative to foot-operated on the slip ring of axis biased forward, and is led between slip ring and axis Telescopic arm is crossed to connect, rides when riding and is rotated by axis of the center of clamping rings or slip ring, with common cycling shape State is identical, but since slip ring is relative to axis biased forward, when side it is foot-operated in axis front upper when, ride with axis it Preceding torque increases, with regard to more laborsaving when stepping under in this way；And when the side foot-operated is located at rotation to the axis back lower place, the other side The foot-operated front for just going to axis top, increase the arm of force when firmly to step on down to improve torque, and rotate into It is not necessary that firmly, to realize foot-operated labour-saving function, the utility model has structure more compared with the existing technology when axis rear Rationally, the characteristics of easy for installation, good reliability.

Specific embodiment

As shown in figures 1 to 6, a kind of power-saving pedal for bicycle mechanism, including vehicle frame 1, axis 2, flywheel 3, chain 4, sprocket wheel 5 With foot-operated 6, the left and right sides of the vehicle frame 1 is also fixed with clamping rings 7, the position of the corresponding vehicle frame 1 of the clamping rings 7 Place, which opens up, sets screw hole, and clamping rings 7 is fixed by screws on vehicle frame 1, and the axis 2 is in clamping rings 7, and solid Determine biased forward of the center of annulus 7 relative to axis 2, slip ring 8, slip ring 8 and clamping rings 7 are set in 7 inner edge of clamping rings It is coaxially disposed, ball or roller is set between 7 inner edge of 8 outer rim of slip ring and clamping rings and can be branch with clamping rings 7 Frame rotates freely in clamping rings 7, is connected between the slip ring 8 and the end of axis 2 by telescopic arm 9, telescopic arm 9 one End is fixed on the end of axis 2, the other end and is hinged on slip ring 8；Foot-operated 6 shaft is connected in the outside of slip ring.

Foot-operated shaft is connected in the outside of slip ring by the utility model, while by the rotation center of slip ring relative to axis Biased forward, for the purpose being arranged in this way when stepping on firmly under foot-operated, the arm of force is longer relative to common foot pedal structure, to generate more Big torque, to realize labour-saving purpose；In addition slip ring is arranged at clamping rings inner edge the utility model, by clamping rings The positioning to slip ring is realized while being fixed on vehicle frame, and slip ring is connect with axis by telescopic arm, telescopic arm one end is straight It connects and is connected with axis, the other end is hinged with slip ring, and compared with the existing technology, the telescopic arm and clamping rings of the utility model are in In same plane, the free end that flexible wall does not also stretch out, in this way it is possible to prevente effectively from there is card bottom of s trouser leg event, safety is more It is good, while installation is also more convenient, relative to the fit system of bearing holder (housing, cover) and telescoping crank, structure is more reasonable.

The utility model is in order to easier for installation, by the shaft ridden while the pivot for being used as telescopic arm to connect with slip ring Axis considers without connected position between clamping rings lower part and the vehicle frame of bicycle, under the clamping rings at left and right sides of vehicle frame Connecting rod is also set up between the outer rim of portion or bottom, connecting rod is arranged in parallel with axis, by connecting rod reinforcement slip ring and admittedly Determine the intensity of annulus lower part, is in the long-term use not in deformation, to promote the reliability of product.

In addition customization vehicle frame also can be used in the utility model, is arranged around the axis of vehicle frame and clamping rings cooperation Fixed part, such clamping rings is fixed and integral installation is more convenient.
