Embodiment Construction

[0009] The specific structure and working conditions of the present invention will be described in detail below with reference to the drawings.

[0010] The front wheel (1) of the pedal tricycle driven by the seesaw is about 10cm in diameter, the rear two wheels (2) are about 25cm in diameter, and the front wheel (1) is between the steering shaft sleeve and the rear wheel shaft (15) as the beam (3) , The car beam (3) has a car plate (4), the front wheel (1) and the handlebar (5) above the upright lock on the steering shaft sleeve can be folded forward. When the traction handle is used, it can be folded backward for easy carrying , The upright lock is the direction of the tricycle; the rear wheel (2) is two bicycles with flywheels (7). The rear wheels are installed on the same rear axle (15), and both flywheels are installed on the rear wheels (2) The two flywheels (7) both have the function of driving the wheels forward in one direction. The teeth of the two flywheels a...

Abstract

The invention relates to a teeterboard-driven trishaw. The teeterboard-driven trishaw is that a front wheel is about 10cm in length, and two rear wheels are about 25cm in diameter; a beam is arranged between a steering axle sleeve of the front wheel and rear wheel axles; a board is arranged on the beam; a handle above a vertical lock on the upper surface of the front wheel steering axle shaft can be folded and turned back; when a traction handle is backwards overlapped, the carrying is convenient; a steering handle head of the trishaw can be vertically locked; the rear wheels are two bicycle rear wheels provided with fly wheels and mounted on the same rear axle; the two fly wheels are mounted at the inner sides of the rear wheels and both have the function of driving the wheels to move forwards in one direction; teeth of the two fly wheels are tapered rather than quadrangular; arc-shaped racks of which the top and bottom are provided with the tapered teeth engage with the tapered teeth of the fly wheels, wherein the arc-shaped racks are arranged at two ends of a teeterboard which rotates around the beam; the teeterboard can rotate up and down within 15 degrees; when the trishaw is used as a luggage barrow, the rear wheel axles and the teeterboard are provided with tilting stopping type horizontal inserting pins. The teeterboard-driven trishaw needs a small space, and is small in size and light in weight.

Description

Technical field [0001] The invention belongs to the technical field of manpowered vehicles and relates to a manpowered pedal tricycle. Background technique [0002] The existing human-powered pedal tricycles generally have saddles, pedal wheels and chains. Such tricycles occupy a large space, are bulky, have a heavy body, cannot be folded, are not easy to carry, and are not suitable for use in luggage carts. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a seesaw-driven pedal tricycle without a saddle, pedal wheels and chains, which occupies a small space, is small in size, has a light body, can be folded forward and folded back, and is easy to carry. It can be used as a walking tool and as a luggage cart when going out. [0004] The technical solution adopted by the present invention is: the front wheel diameter of the pedal tricycle is about 10cm, and the diameter of the rear two wheels is about 25cm. Between the front ...
