Abstract:
A double-directional rotary water ball structure comprising a water ball and a base seat disposed under the water ball, an internal rotary view being disposed in the water ball and an external view being disposed on an outer side of the base seat, wherein: the base seat is composed of a disc-shaped base board, a music bell, a table-type support, a rotary tray, a pressing cover and a transmission claw, the table-type support being disposed with support legs thereunder for riding and fixed on the base board by screws, the music bell being positioned between the support legs and secured on the base board by screws, a music roller being disposed on one side of the music bell, having a transmission shaft extending through the table-type support, a driving gear being disposed at an upper end of the transmission shaft above the table-type support; a power shaft protrudes beyond the music bell and is fitted with a center gear which cooperates with the power shaft, a lower side of the center gear being disposed with a driven gear, a central shaft projecting upward from the driven gear, a top end of the central shaft being formed with a rectangular post which is engaged with the transmission claw, the driven gear meshing with the driving gear so as to transmit rotational power to the transmission claw; the rotary tray is fitted around the table-type support, the pressing cover being secured on the support by screws, a fitting ring being fitted around a projecting boss of the rotary tray, the rotary tray being a hollow body, the external view design being fixed on outer circumference of the rotary tray and rotatable along therewith, an inner gear being disposed on inner circumference of the rotary tray, whereby when the rotary tray is fitted around the support, the inner gear is right engaged with the driving gear so as to transmit the rotational power to the external view; and by means of the cooperation between the inner and outer gears, the rotary tray and the transmission claw connected to the driven gear are respectively driven to rotate in opposite directions, whereby the internal view of the water ball driven by the transmission claw and the external view disposed on the base of the rotary tray are rotated in opposite directions so as to create a double-directional rotation visual effect.
