Description

But the forward and backward all devices of cruising of pedaling of a kind of bicycle

Technical field the utility model belongs to bicycle accessories, but relates to the forward and backward all devices of cruising of pedaling of a kind of bicycle.

The background technology bicycle is the most frequently used a kind of vehicle of people, uses more convenient.Traditional bicycle can only be pedaled forward under steam, easily produces sense of fatigue when riding for a long time.The utility model is but that the forward and backward all devices of cruising of pedaling of bicycle are installed on bicycle rear, makes the people that rides increase the amusement sense, when shank for a long time can be done the reversing sense motion doing same direction kinaesthesis,

But the summary of the invention the purpose of this utility model provides the forward and backward all devices of cruising of pedaling of a kind of bicycle, the difficult sensation that produces fatigue of Shi Renhui of riding for a long time like this.

Pedal all device context summaries of cruising but the utility model bicycle is forward and backward:

But the forward and backward all devices of cruising of pedaling of the utility model bicycle, be to constitute by helical wheel, center shaft, change wheel, bearing, ball, baffle plate, helical wheel, pin, main shaft, sprocket wheel, slide block, pin, spring, baffle plate, support, nut, axle, it is characterized in that: a helical wheel is fixed on the main shaft, helical wheel and the engagement of change wheel, become wheel and rotate around center shaft, center shaft is fixed by bearing and support; The helical wheel and the slide block that become the wheel right side place within the sprocket wheel, and helical wheel rotates under the cooperation of ball, baffle plate, and slide block rotates under the cooperation of ball, baffle plate; Slide block and main shaft are fixed together, at the right side of baffle plate fixed support, be fastened on the axle that places in the main shaft by nut, axle is connected and fixed with support and bicycle body's support, on the inwall of sprocket wheel, have 4～6 with helical wheel, the opposed sulculus of slide block, a pin and spring are respectively arranged in the groove.

But the forward and backward all devices of cruising of pedaling of the utility model bicycle, for bicycle provide a kind of forward and backward pedal can cruising device, will be not easy to produce tired sensation people people when riding for a long time like this, increase amusement sense by bike.The back-pedal bicycle with normally by bike custom disagree, so both tempered the different muscle of shank, strengthened people's coordination of body ability again, promotion human thinking ability.

But description of drawings Fig. 1 is the forward and backward apparatus structure scheme drawings of cruising of pedaling of bicycle

Among Fig. 1: 1 be bicycle rear, 2 for helical wheel, 3 for center shaft, 4 for become wheel, 5 for bearing, 6 for ball, 7 for baffle plate, 8 for helical wheel, 9 for pin, 10 for main shaft, 11 for sprocket wheel, 12 for slide block, 13 for pin, 14 for spring, 15 for baffle plate, 16 for support, 17 for nut, 18 for spool

Specific embodiment the utility model is to realize like this, see Fig. 1, but pedal the right side that devices of cruising all is installed in the center shaft of bicycle rear with bicycle is forward and backward, one helical wheel 2 is fixed on the main shaft 10, helical wheel 2 and 4 engagements of change wheel, becoming wheel 4 rotates around center shaft 3, center shaft 3 is fixing by bearing 5 and support 16, the helical wheel 8 that becomes wheel 4 right sides places within the sprocket wheel 11 with slide block 12, helical wheel 8 rotates under the cooperation of ball 6, baffle plate 7, and slide block 12 rotates under the cooperation of ball 6, baffle plate 15; Slide block 12 is fixed together with main shaft 10, at the right side of baffle plate 15 fixed support 16, be fastened on the axle 18 that places in the main shaft 10 by nut 17, axle 18 is connected and fixed with support 16 and bicycle body's frame, on the inwall of sprocket wheel 11, have 4～6 with helical wheel 8, slide block 12 opposed sulculuses, a pin 9 is respectively arranged in the groove and sells 13, at forward to pedal the time, chain is meshed with tooth on the sprocket wheel 11, drives sprocket wheel 11 and does equidirectional rotation; One end of pin 13 is upspring in the sulculus by slide block 12 under the effect of spring 14, blocks the sulculus on the corresponding with it sprocket wheel 11, makes slide block 12 connect equidirectional rotation with sprocket wheel 11; Slide block 12 is fixed together with main shaft 10, equidirectional rotation, and bicycle rear 1 is captiveed joint with main shaft 10, and equidirectional rotation has realized the cruising when the bicycle forward is to pedal.Oppositely to pedal the time, chain is meshed with tooth on the sprocket wheel 11, drives sprocket wheel 11 and does equidirectional rotation; One end of pin 9 is upspring in the sulculus by helical wheel 8 under the effect of spring 14, blocks the sulculus on the corresponding with it sprocket wheel 11, makes helical wheel 8 connect equidirectional rotation with sprocket wheel 11; Helical wheel 8 is meshed with change wheel 4, making change wheel 4 is being that rotate in the axle center with center shaft 3, and 4 whiles of change wheel are meshed with helical wheel 2, make helical wheel 2 counter-rotation, helical wheel 2 is captiveed joint equidirectional rotation with main shaft 10, bicycle rear 1, realized the oppositely cruising to pedal time of bicycle.
