ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a double-directional rotary water ball structure in which a specific transmission mechanism is disposed in a base seat of the water ball, whereby an internal view of the water ball and an external view disposed on outer side of the base seat are rotated in reverse directions so as to create a double-directional rotation visual effect.
A watching water ball is designed with internal dynamic view which is rotatable with a music bell so as to create a visual entertaining effect. However, the existing commercially available water ball products are varied from each other only in the internal view design and rotational direction. The water balls are rarely entirely changed.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a double-directional rotary water ball which has simple and compact structure and can be easily and quickly assembled and disassembled. The water ball is manufactured at low cost without easy damage.
In order to achieve the above object, the water ball structure of the present invention includes a base seat and a music bell disposed in the base seat. A transmission shaft extends from the music bell for outputting rotational power. A driving gear is fitted with the transmission shaft for transmitting the power respectively to a central driven gear and an inner gear disposed on inner circumference of a rotary tray. Accordingly, the rotary tray and a transmission claw connected to the driven gear are respectively driven to rotate in reverse directions, whereby the internal view of the water ball and the external view disposed on the rotary tray are rotated in reverse directions so as to create a double-directional rotation visual effect.
The present invention can be best understood through the following description and accompanying drawings, wherein:
