The purpose of this utility model is to provide a kind of light and handy water cycle.

The technical solution of the utility model is achieved in that water cycle, it mainly comprises car body, be contained in cushion rack, handlebar and transmission device on the car body, on cushion rack, be provided with seat cushion, it is characterized in that: car body is ship shape, is provided with the yaw rudder that is connected with handlebar at the lower end near car body, also establishes a screw propeller at the lower end near car body, one end of rotating shaft is captiveed joint with screw propeller, and the other end of rotating shaft is equipped with gear 19; At the two ends of transmission shaft gear 8 and gear 18 are housed respectively, gear 8 and the engagement of step bonded assembly flywheel, gear 18 and gear 19 engagements.

The utility model is owing to be designed to be ship shape with car body, be provided with the yaw rudder that is connected with handlebar at lower end near car body, also establish a screw propeller at lower end near car body, the place ahead of having adopted bicycle is to principle, and transmission device improved, volume is little, in light weight, total weight is no more than 50 kilograms, and maximum the heavy burden is 140 kilograms, and speed is fast, the time 18 kilometers of scooters, easy to operate, can be used as a kind of energy that do not need, free of contamination marine communication means is walked out park and recreation ground, also is a kind of comparatively desirable aquatic sports equipment and recreation articles for use simultaneously.

Fig. 1 is the scheme drawing of the utility model one embodiment

Fig. 2 is the transmission device scheme drawing among Fig. 1

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises car body 1, be contained in cushion rack 12, handlebar 3 and transmission device on the car body 1, on cushion rack 12, be provided with seat cushion 13, it is different from prior art and is: car body 1 is ship shape, car body is designed to the front end point obtains stream line pattern for reducing the resistance present embodiment, handlebar 3 is contained in the front of car body 1, be provided with the yaw rudder 4 that is connected with handlebar 3 at lower end near car body 1, the front-wheel of this yaw rudder and bicycle is the same to have played controlling party to, the vital function of adjustment; For the ease of stop putting, in car body, be provided with ball float support 9 in force, on ball float support 9, strut bar 15 is housed near the both sides of car body 1, ball float 6 and spring 14 are housed on strut bar 15; The utility model improves the transmission device of bicycle, also establishes a screw propeller 2 at the lower end near car body 1, and an end of rotating shaft 10 is captiveed joint with screw propeller 2, and the other end of rotating shaft 10 is equipped with gear 19; At the two ends of transmission shaft 17 gear 8 and gear 18 are housed respectively, gear 8 and 7 engagements of step 5 bonded assembly flywheels, this flywheel 7 is different with general flywheel, also is a crowngear, gear 18 and gear 19 engagements; Gear 8, gear 18 and gear 19 are crowngear, they all are contained on the gear stand 11, mark 16 in the accompanying drawing is foot-operated bent axle, consider the speed of travelling, flywheel 7 in the present embodiment adopts 100 yards crowngear, gear 8, gear 18 and gear 19 are 20 yards crowngear, differential ratio between them is 1: 5, be that pin is stepped on a circle, by flywheel 7 and gear 8, gear 18, cooperation between the gear 19, the rotation of screw propeller 2 is five circles, two ball floats 6 of car body 1 both sides have played the effect same with the bicycle spike, when riding, can rise ball float, strut bar can be put down when stopping, need only when braking and step on several circles as needs, in distance obstacle 1-2 rice, can stop, in order to prevent to intake in the car body, rotating shaft 10 and screw propeller 2 carry out bonded assembly and stretch out the car body place and will seal, handlebar 3 stretches out the car body place with yaw rudder 4 bonded assemblys and also will seal, and the car body length overall of present embodiment is 200 centimetres, and width is 54 centimetres, the diameter of screw propeller is 36 centimetres, Revolution Per Minute can reach 320 circles, and the car body thickness is 46 centimetres, and total weight is 48 kilograms.

Use the utility model will possess several conditions, one is able to swim; Two can be by bike; The 3rd, healthy, no hypertension, disease such as cardiovascular; The 4th, the best uses object to be the young and the middle aged, will put on life jacket in addition, does a little warming-up exercises; Dynamic process of the present utility model is, step on step 5, drive flywheel 7 by foot-operated bent axle 16 and rotate, because flywheel 7 and gear 8 engagements, driven gear 8 rotates again, because gear 8, gear 18 are packed in the two ends of turning cylinder 17, and therefore gear 18 and gear 19 engagements rotate gear 18 by transmission shaft 17, rotate by gear 18 driven gears 19 again, by rotating shaft 10 screw propeller 2 is rotated again, travel thereby drive this water cycle.
