Description

Bicycle

Technical field

The utility model relates to a kind of bicycle.

Background technology

At present, the mode that standard bicycle pedal when driving is travelled adopts around the axle circular movement, when pedal during in the axis dead ahead, power arm moment maximum, when pedal during at top dead point and bottom dead point, power arm moment is zero, what this moment, manpower was done is idle work.The standard bicycle saddle is done upper and lower adjustment for the people who adapts to different statures, center of gravity height, poor stability.

Summary of the invention

The purpose of this utility model is to provide a kind of laborsaving and safe bicycle.

The purpose of this utility model is achieved through the following channels: bicycle, it comprises main car frame, steering hardware, the rear portion of main car frame is equipped with rear wheel frame, rear wheel frame is equipped with road wheel by rear drum, the termination at main car frame rear portion is equipped with saddle, the front end of main car frame is fixed with pedals the bar axle, and the two ends of pedaling the bar axle are separately installed with that bar is pedaled on a left side and bar is pedaled on the right side, and bar is pedaled on a left side and the right other end termination of pedaling bar is separately installed with left-hand tread plate and right-hand tread plate; Rear drum two ends on the rear wheel frame are installed left flywheel and right flywheel respectively, and the rear wheel frame front bottom end is horizontally installed with pulley; Left lever, right pull bar one end connect respectively that bar is pedaled on a left side and bar is pedaled on the right side, and the other end is connected with left chain and right chain respectively, and left chain, right chain walk around left flywheel respectively and right flywheel is connected with the steel rope of walking around pulley.The saddle rear end is equipped with backrest, and adjusting can be moved in the position of saddle on the saddle regulating plate of its lower end.Bar is pedaled on a left side and the right bar of pedaling is provided with some in order to connect the gear hole of left lever and right pull bar.Position-limited lever is fixed on a left side and pedals bar and right pedaling on the main car frame in bar the place ahead.

The utility model bicycle has changed the mode of pedal around circular movement, and pedal is pedaled toward the front lower place, and back and forth movement before and after doing has not had upper and lower stop, has reduced the idle work of manpower, so the utility model bicycle is more laborsaving than standard bicycle.The utility model bicycle is to do the motion of pedaling forward, and saddle needn't be done very highly, also needn't do upper and lower adjustment, can do fore-and-aft adjustment according to people's stature, so rod-pulling type bicycle center of gravity is lower than standard bicycle, and safety is better.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model partial enlarged drawing.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model bicycle, it comprises main car frame 16, steering hardware 23, the rear portion of main car frame 16 is equipped with rear wheel frame 20, rear wheel frame 20 is equipped with road wheel 22 by rear drum 12, the termination at main car frame 16 rear portions is equipped with saddle 17, the distinctive points of this bicycle and standard bicycle is: the front end of main car frame 16 is fixed with pedals bar axle 1, the two ends of pedaling bar axle 1 are separately installed with that bar 4 is pedaled on a left side and bar 3 is pedaled on the right side, and bar 4 is pedaled on a left side and the right other end termination of pedaling bar 3 is separately installed with left-hand tread plate 5 and right-hand tread plate 2; Rear drum 12 two ends on the rear wheel frame 20 are installed left flywheel 15 and right flywheel 13 respectively, and rear wheel frame 20 front bottom end are horizontally installed with pulley 9; Left lever 8, right pull bar 7 one ends connect respectively that bar 4 is pedaled on a left side and bar 3 is pedaled on the right side, and the other end is connected with left chain 14 and right chain 11 respectively, and left chain 14, right chain 11 walk around left flywheel 15 respectively and right flywheel 13 is connected with the steel rope 10 of walking around pulley 9.

Saddle 17 is connected with main car frame 16 by saddle regulating plate 18, and a plurality of screws are arranged on the saddle regulating plate 18, can be used for the front and back adjusting of saddle 17 and is adapted to the people of different statures.Backrest 19 has been installed at saddle 17 rear portions, in the time of can making Pedalling the back reliable and better firmly, take advantage of seat also more comfortable, safer simultaneously.

Bar 4 is pedaled on a left side and the right bar 3 of pedaling is provided with in order to connect the gear hole 21 of left lever 8 and right pull bar 7, can be according to the size adjustment left lever 8 of manpower and the position in hole, 7 engage a gear positions of right pull bar 21.

Position-limited lever 6 is fixed on a left side and pedals bar 4 and right pedaling on the main car frame 16 in bar 3 the place aheads, when being used to prevent to pedal a left side is pedaled the bar 4 and the right side and pedals bar 3 and pedal to wheel position, avoids a left side to pedal bar 4 and the right side and pedals bar 3 and stretch longly and disturb the bicycle normal direction of rotation.

The principle of work of the utility model bicycle is as follows:

When with pedal right-hand tread plate 2, right-hand tread plate 2 is fixed on the right side and pedals on the bar 3, and the right side is pedaled bar 3 and is the summit swing according to pedaling bar axle 1, and right pull bar 7 connects the right side and pedals bar 3 and right chain 11, and right chain 11 drives road wheel 22 by right flywheel 13 and advances.Right chain 11 is walked around pulley 9 by steel rope 10 and is connected with left chain 14, left chain 14 walks around that left flywheel 15 is pedaled bar 4 with left lever 8, a left side, left-hand tread plate 5 is connected, when pedaling right-hand tread plate 2 on earth forward, because right chain 11 is walked around pulley 9 by steel rope 10 and is connected with left chain 14 grades, when advancing, ground-engaging wheel 22 just left-hand tread plate 5 is withdrawn into the back stop, when left-hand tread plate 5 is pedaled forward, same when ground-engaging wheel 22 advances right-hand tread plate 2 toward post-tensionings, so the back and forth movement of left-hand tread plate 5, right-hand tread plate 2 just can drive bicycle and advance.
