Double-wheel waterborne recreation car

Abstract

The invention provides a double-wheel waterborne recreation car which comprises a pair of wheel shells connected through a center connecting shaft, wherein, the wheel shells are internally equipped with semicircle brackets; seats are arranged on the semicircle brackets, supporting rollers are arranged on two ends of the rear surfaces of the semicircle brackets, and the middle parts of the semicircle brackets are connected with friction rollers which are driven by a transmission mechanism to rotate and are connected with guide rails on the internal surfaces of the wheel shells; the semicircle brackets are formed by integrating first semicircle bracket sections with second semicircle bracket sections through movable connecting pieces; and the seats are arranged on one of the semicircle bracket sections, and tension springs are arranged between seat bases and the other semicircle bracket section. The double-wheel waterborne recreation car can automatically compensate matching errors between the wheel shells and the semicircle brackets, thus effectively solving the problem that the shells are easily stuck in case of relative rotational motion between the inner rings of the wheel shells and semicircle seat rings, achieving smooth and flexible operation of the waterborne recreation car, and being beneficial to realizing a strong movement entertainment function; and in addition, the wheel shells are hollow and sealed, thus further enhancing the buoyancy and improving the safety performance.

Description

technical field [0001] The invention relates to a buoyancy amusement device on water. Background technique [0002] The applicant once designed a kind of " twin-body wheeled rudderless pedal boat ", and the patent No. is ZL200610052572.X. It includes a hull, a seat and a main drive wheel driven by a pedal mechanism, and its hull is composed of a pair of wheel shells connected through a central connecting shaft. There are entrances and exits, paddle blades are evenly distributed on both sides of the wheel circumference, and an inner bracket composed of a central pole and a semicircular seat is arranged in the wheel shell. The friction roller connected to the guide rail on the inner surface of the shell, the middle and lower part of the central pole is equipped with a sprocket driven by a pedal, the friction roller at the lower end of the central pole is the main transmission wheel, and a sprocket is installed on the central shaft at the same time. The sprocket is connect...

Problems solved by technology

However, it has been found through practice that since the roundness processing of the inner ring of the wheel housing and the semicircular seat ring is difficult to be very precise, during its relative rotational movement, a jamming failure often occurs, affecting normal operation and use.
