Description

Bicycle buncher

Technical field

The utility model is related to speed changers, and in particular to a kind of bicycle buncher.

Background technology

Currently, ordinary bicycle is with foot-operated floral disc, by chain drive to flywheel, belong to wheel shaft lever motion, but due to Wheel is smaller with axis radii ratio, and labor-saving effect is still not ideal enough；In addition faceplate diameter is larger, and flywheel diameter is smaller, driving chain It is larger with horizontal line angle, the power of transmission has been decomposed, still can have been felt when riding laborious.

Invention content

The purpose of this utility model is：A kind of bicycle buncher is designed, simple in structure, of low cost, lever is former Reason cycles laborsaving, suitable climbing.

The technical solution of the utility model is：The bicycle includes vehicle frame, foot-driven lever and rides, and a pair of of foot-driven lever is logical Shaft is crossed on vehicle frame, rides and is mounted on foot-driven lever, it is characterized in that：Buncher is installed on bicycle, it is described Buncher include long axis, pitman shaft, hand handle runner, latch, steel wire rope, runner, sliding block, rack bar, unidirectional up time Pin gear, unidirectional inverse time pin gear, No.1 gear wheel, No. two gear wheels and central shaft, long axis are mounted on vehicle frame, and the two of long axis End connects foot-driven lever by pitman shaft respectively, and the hand handle runner of locking stops is mounted on the handlebar, and runner, steel are installed in foot-driven lever Cord is wrapped on hand handle runner and runner, and sliding block is fixed on steel wire rope, passes through the unidirectional tooth clockwise of central shaft installation on vehicle frame Wheel and No. two gear wheels, unidirectional inverse time pin gear and No.1 gear wheel are mounted on by axis on vehicle frame, No.1 gear wheel engagement two One end of number gear wheel, rack bar is flexibly connected sliding block, and the other end of rack bar is mounted on vehicle by two runners and link block On frame and the rack of rack bar is made to engage unidirectional up time pin gear and unidirectional inverse time pin gear.

Wherein, protecting tube is set on steel wire rope, one end of protecting tube connects hand handle runner, the other end connecting pin of protecting tube Treadle.

The principles of the present invention are：Ratchet is only rotated to direction, and when own rotation will not drive following Bull gear drive, negative direction is to be locked, and own rotation is not；When negative direction rotation by it is locked when, then can drive following Gear wheel rotate together；Rack bar directly acts on ratchet, and following gear wheel is driven by ratchet.

The utility model has the advantages that：It is simple in structure, it is of low cost, it is easy to operate, it without gear, will not skid, run Stablize.

Specific implementation mode

The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1, 2, which includes vehicle frame, foot-driven lever 1 and foot-operated 2, and a pair of of foot-driven lever 1 is installed by shaft 3 On vehicle frame, rides 2 and be mounted on foot-driven lever 1, it is characterized in that：Buncher, the electrodeless change are installed on bicycle Fast device includes long axis 4, pitman shaft 5, hand handle runner 6, latch 7, steel wire rope 8, runner 9, sliding block 10, rack bar 11, unidirectional suitable Hour hand gear 12, unidirectional inverse time pin gear 13,14, No. two gear wheels 15 of No.1 gear wheel and central shaft 16, long axis 4 are mounted on vehicle On frame, the both ends of long axis 4 connect foot-driven lever 1 by pitman shaft 5 respectively, and the hand handle runner 6 of locking stops 7 is mounted on the handlebar, Runner 9 is installed, steel wire rope 8 is wrapped on hand handle runner 6 and runner 9, fixes sliding block 10 on steel wire rope 8, on vehicle frame in foot-driven lever 1 Unidirectional up time pin gear 12 and No. two gear wheels 15, unidirectional inverse time pin gear 13 and No.1 gear wheel 14 are installed by central shaft 16 It being mounted on vehicle frame by axis, No.1 gear wheel 14 engages No. two gear wheels 15, and one end of rack bar 11 is flexibly connected sliding block 10, The other end of rack bar 11 is mounted on vehicle frame by two runners and link block 17 and keeps the rack engagement of rack bar unidirectional suitable Hour hand gear 12 and unidirectional inverse time pin gear 13.

Wherein, protecting tube 18 is set on steel wire rope 8,18 one end of protecting tube connects hand handle runner 6, and 18 other end of protecting tube connects Pin treadle 1.

When work, when step on side it is foot-operated when, the foot-operated of the other side can rise, at the same foot-driven lever drive rack bar 11 to Preceding movement, rack bar 11 drive unidirectional up time pin gear 12 to rotate counterclockwise, and unidirectional up time pin gear 12 is up time pinwheel, inverse time Needle rotation can lock, and accordingly No. two gear wheels 15 be driven to rotate counterclockwise, and No. two gear wheels 15 drive 14 up time of No.1 gear wheel Needle rotates, and corresponding unidirectional inverse time pin gear 13 rotates clockwise, and unidirectional inverse time pin gear 13 is inverse time pinwheel, is rotated counterclockwise It will not be locked with the No.1 gear wheel 14 rotated clockwise, when No. two gear wheels 15 rotate, central shaft 16 be driven to rotate counterclockwise, Vehicle wheel rotation on central shaft 16；On the contrary, when step on the other side it is foot-operated when, drive rack bar 11 to move backward, rack Bar 11 drives unidirectional inverse time pin gear 13 to rotate clockwise, and unidirectional inverse time pin gear 13 is inverse time pinwheel, and rotating clockwise can lock Extremely, accordingly No.1 gear wheel 14 is driven to rotate clockwise, No.1 gear wheel 14 drives No. two gear wheels 15 to rotate counterclockwise, relatively The unidirectional inverse time pin gear 13 answered is up time pinwheel, and rotating clockwise will not lock with No. two gear wheels 15 turned counterclockwise, together Belt transect moves central shaft 16 and rotates counterclockwise；Hand handle runner 6 rotates, and latch 7 does not lock, when hand handle runner 6 does not turn, latch 7 It is locked motionless；When the hand handle runner 6 in the hand handle that rotates backward, steel wire rope 8, steel wire rope 8 is driven to rise to foot with movable slider 10 Treadle topmost, throw of lever at this moment is big, and suitable bicycle fast moves, when rotating hand handle runner 6 forward, band movable slider 10 drop to foot-driven lever lowest part, and throw of lever at this moment is small, according to lever principle, cycle most laborsaving, suitable climbing, sliding block 10 According to the mobile any position between the top and lower curtate of foot-driven lever of adjusting of hand handle runner 6, the electrodeless change of bicycle is realized Speed.
