Abstract

The utility model relates to a bamboo raft bicycle on water, which comprises a floating body, a bicycle frame, a rudder and a pedal power device. The floating body is composed of a left raft and a right raft; the pedal power device is composed of a pedal with in-line gears, a chain, an impeller with in-line gears; the gears can be driven by the pedal; the impeller can rotate by the transmission of the chain. The utility model has the advantages of simple structure, convenient operation, good steady performance, flexible turning and free advance and retreat. The utility model can be used as the vehicle of the area (such as reservoirs) of wide water surface, and can be used as the tool of parks for amusement or match.

Description

Bamboo raft bicycle waterborne

This practicality relates to a kind of water cycle, particularly a kind of bamboo raft bicycle waterborne.

Existing bamboo raft all is to tie up with row's bamboo raft to form, drive or go downstream by the manpower strut, big, the flexible poor-performing of this raft volume, generally be suitable for the anxious river course of the shallow and current of water such as brook, river and use, the relatively slow and darker waters to current (as reservoir etc.) uses very inconvenient.

The purpose of this utility model is that the shortcoming that overcomes above-mentioned raft provides less, rational in infrastructure, the flexible performance of a kind of volume good bamboo raft bicycle waterborne.

This bamboo raft bicycle waterborne comprises buoyancy aid, vehicle frame, yaw rudder and pedal power device, described buoyancy aid by about two bamboo rafts form, the pedal power device is made up of foot-operated, chain that has in-line gears and the impeller that has in-line gears, by foot-operated driven gear, make wheel rotation by chain gear, finish its driving process.

Yaw rudder of the present utility model is made up of handrail, steering wheel, small sheave, driving band and rudder, handrail and steering wheel link rotation, steering wheel and two small sheaves are equicrural triangle and arrange, be wound with driving band between the three, driving band mid point between the front end of rudder and two small sheaves links, and middle part and vehicle frame have a fulcrum.By rotating handrail, driving band is moved, thereby the direction of rudder is changed like this.

The utlity model has simple in structure, easy to operate, balance quality is good, turn to advantage flexible, free to advance or retreat.Both can be used as the vehicle in the wide area of a kind of water surface, can make the instrument of park amusement on water or contest again.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model yaw rudder;

Below in conjunction with description of drawings structure of the present utility model, as shown in Figure 1, connect to car body by vehicle frame 3 by two bamboo rafts 1, car body is provided with yaw rudder and pedal power device.The impeller 7 that the pedal power device comprises foot-operated 5, the chain 6 that has in-line gears 4 and has in-line gears is formed.Firmly pedal foot-operatedly 5 the time as the people, gear 4 is rotated, the gear of chain 6 impeller 7 by interlock with it rotates, and strikes thereby impeller 7 is rotated, and car body is advanced.Impeller 7 tops are provided with water cover 8, and anti-sealing turns over and spatters up.

The structure of yaw rudder as shown in Figure 2, it is made up of handrail 2, steering wheel 9, pulley 10, driving band 11 and rudder 12.Steering wheel 9 is provided in a side of the runner under the handrail 2, links with handrail 2 and rotates.Steering wheel 9 and two small sheaves 10 that are equicrural triangle with it are around with driving band 11.Rudder body 12 is located under water, and driving band 11 mid points between its front end and two small sheaves link, and there is a fulcrum at its middle part with vehicle frame.By rotating handrail 2, driving band 11 is moved like this, thereby the direction of rudder is rotated.

Claims

1, a kind of bamboo raft bicycle waterborne, comprise buoyancy aid, vehicle frame, yaw rudder and pedal power device, it is characterized in that described buoyancy aid by about two bamboo rafts form, the pedal power device is made up of foot-operated, chain that has in-line gears and the impeller that has in-line gears, by foot-operated driven gear, make wheel rotation by chain gear.

2, bamboo raft bicycle waterborne according to claim 1, it is characterized in that described yaw rudder is made up of handrail, steering wheel, small sheave, driving band and rudder, handrail and steering wheel link rotation, direction is changeed and two small sheaves are the equicrural triangle arrangement, be wound with driving band between the three, driving band mid point between the front end of rudder and two small sheaves links, and middle part and vehicle frame have a fulcrum.
