Description

Water cycle

The utility model relates to a kind of riding utensil waterborne, particularly a kind of water cycle.

Current non-maneuverable traffic waterborne and entertainment and sports device are exactly various types of ships that the people shakes.The common ground of these ships is exactly the upper limbs force of personnel selection, shakes slurry or scull ship is advanced.Because the strength of the relative lower limb of strength of people's upper limbs is little, so the speed that ship is advanced in water is unhappy, and the fatigue of people's susceptible.

The purpose of this utility model drives the waterborne riding device that it advances with regard to the lower limbs strength that provides a kind of personnel selection.

The technical solution of the utility model is that it has vehicle frame, handlebar, vehicle seat and is loaded on the axis of central frame beam bottom, be equipped with at the two ends of axis and have foot-operated crank, it is characterized in that in the endoporus of vehicle frame front portion handlebar axis being housed, handlebar is contained in the upper end of handlebar axis, and rudder is equipped with in the lower end of handlebar axis; Floating drum is equipped with in both sides in the vehicle frame bottom; Below the vehicle frame afterbody rear axle is housed, the rear end of rear axle is equipped with and is advanced the blade wheel, and rear axle is driven through speed-changing mechanism by rotating crank.

Simple in structure in order to make, reliability and durability, the speed-changing mechanism of this water cycle can be by being contained in the bevel gear on axis one side and constituting with bevel gear that its ingear is contained in the rear axle front end.

Because this water cycle all is equipped with a floating drum in the both sides of vehicle frame bottom, thus when the people drives, can be floating in water surface balance, can be not banking.When the people rode, with foot-operated moving foot-operated, crank drove axis and rotates, and by the bevel gear pair, drives rear axle and rotates, and the propelling blade wheel that is contained in the back shaft rear end like this rotates, and has just promoted water cycle and has advanced.And change the ratio of number of teeth of bevel gear pair, can change gait of march and people's firmly degree.Rotate handlebar with hand, the rudder that is contained in the handlebar axis lower end is rotated, so just can change the direction of advancing.So this bicycle safety very easy to use.Because it is the strength of personnel selection lower limb,, wants fast so its gait of march is rowed the boat with upper limbs, and be difficult for feeling tired as land bicycle.This water cycle can be used as traffic waterborne or amusement utensil.

Accompanying drawing 1 is an External view of the present utility model;

Accompanying drawing 2 is front axle part assembling drawings of the present utility model

Accompanying drawing 3 is axis of the present utility model and rear axle part assembly drowing.

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

As can be seen from Figure 1, the vehicle frame of the vehicle frame 1 similar bicycle of this water cycle has vehicle seat 2 in the upper back of vehicle frame 1, and different is that front cross rail 3 and after cross member 4 are arranged in the bottom of vehicle frame 1.In the both sides of vehicle frame 1 bottom two floating drums 5 and 6 are arranged, floating drum 5 and 6 is fastened on crossbeam 3 and 4.Find out from Fig. 1 and Fig. 2, handlebar axis 7 is housed in the endoporus of vehicle frame 1 front portion, the back-up ring 9 and 10 that is contained on the handlebar axis 7 is arranged at the upper and lower side of vehicle frame 1 endoporus.Handlebar 8 is equipped with in handlebar axis 7 upper ends.Crossbeam 3 is passed in handlebar axis 7 bottoms, and rudder 11 is fixed by bolts to its lower end.As long as rotate handlebar 8 with hand, just can drive rudder 11 and rotate, change its angle, thereby make water cycle change the direction of advancing.As it is laborsaving flexibly to think that handlebar rotates, and can adopt the structural shape of bicycle handle bar's axle.Find out from Fig. 1 and Fig. 3, axis 12 is housed in the endoporus of vehicle frame 1 middle lower portion, the back-up ring that is contained on the axis 12 is arranged at the two ends of endoporus.The axis structural shape here also can adopt the axis structural shape of bicycle.Also as bicycle, the angle that is equipped with respectively between a crank 13 and 14, two cranks 13 and 14 is 180, and respectively is equipped with one foot-operated 15 and 16 on it at the two ends of axis 12.On the right side of vehicle frame 1, installing bevel gear 17 on the axis 12, it is meshed with bevel gear 18 on being contained in rear axle 19.Rear axle 19 is contained in the endoporus of vehicle frame 1 afterbody lower crossbeam 4 and strut bar 20, and strut bar 20 is welded on two floating drums 5 and 6.Back-up ring 21 and 22 are housed on the rear axle, and rear axle 19 rear ends are equipped with key and are advanced blade wheel 23.High back is low before the rear axle 19, presents the shape that has a down dip, and advances blade wheel 23 to be in water.When riding 15 and 16 with foot-operated moving, crank 13 and 14 is rotated, make the rear axle band propelling blade wheel 23 by bevel gear 17 and 18 and rotate, water cycle just can advance like this.

Claims (2)

1. water cycle, it has vehicle frame, handlebar, vehicle seat and is loaded on the axis of central frame beam bottom, is equipped with at the two ends of axis to have foot-operated crank, it is characterized in that in the endoporus of vehicle frame front portion handlebar axis being housed, handlebar is contained in the upper end of handlebar axis, and rudder is equipped with in the lower end of handlebar axis; Floating drum is equipped with in both sides in the vehicle frame bottom; Below the vehicle frame afterbody rear axle is housed, the rear end of rear axle is equipped with and is advanced the blade wheel, and rear axle is driven through speed-changing mechanism by rotating crank.

2. water cycle according to claim 1, the speed-changing mechanism that it is characterized in that it are by being contained in the bevel gear on axis one side and constituting with bevel gear that its ingear is contained in the rear axle front end.
