DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) Embodiments of the Christmas tree with a rotatable decorative lamp of the present disclosure are described below in further detail by reference to FIG. 1 to FIG. 4.

(7) To ease illustration, relative spatial terms such as above, below, left, right, etc. are employed in the embodiments to illustrate the relationship of one element or feature shown on the drawings relative to another element or feature. It should be understood that besides the orientation shown on the drawings, the spatial terms are intended to cover different orientations of a device in usage or operation. For example, if a device on the drawings is inverted, the element which is described as positioned below other elements or features will be positioned above the other elements or features. As a result, the exemplary term below may include both orientations of above and below.

The drive motor 4 is provided thereon with a transmission shaft 6 connected thereto in a transmission manner. The transmission shaft 6 has an upper end fixedly connected to a lower gear 7. The lower gear 7 is provided on one side with the transmission gear component 5 connected thereto in a transmission manner. The lower gear 7 has an upper end sleeved with a dedicated inner sheath 8. A cylindrical sleeve member 9 runs through a middle part of the dedicated inner sheath 8. A shaft sleeve 10 with a through hole is fixedly connected inside the cylindrical sleeve member 9. A first magnetic connector 11 is mounted inside the through hole of the shaft sleeve 10 through a bearing. The cylindrical sleeve member 9 is formed with a through hole at a bottom thereof, for electrical connection between a storage power supply and the first magnetic connector 11. The cylindrical sleeve member 9 is further fixedly connected to an upper gear 12 that has the same diameter as the cylindrical sleeve member 9 and is connected to the transmission gear component 5 in a transmission manner. The rotatable lamp includes a column body 13 that can be fixed to the shaft sleeve 10 through clamping. The column body 13 has a bottom surface fixedly connected to a second magnetic connector 14 and an upper end fixedly connected to a decorative lamp 15. The first magnetic connector 11 and the second magnetic connector 14 are magnetic male and female connectors mated with one another.

The first gear 51 and the second gear 53 are concentrically and fixedly connected to upper and lower ends of the connecting shaft 52. The first gear 51 is engaged with the upper gear 12 in a transmission manner; and the second gear 53 is engaged with the lower gear 7 in a transmission manner. The dedicated inner sheath 8 is provided thereon with a support column 16 that is integrally formed and coaxial with the connecting shaft 52. The support column 16 has a bottom end fixedly connected to a support bearing 17 that is sleeved on a top of the connecting shaft 52 and positioned above the first gear 51. Below the rotatable lighting unit are provided an optical charging panel 2 and a storage power supply that are connected to one another, and the storage power supply is electrically connected to the first magnetic connector 11 and the drive motor 4. A connecting wire for connecting to the decorative lamp 15 is provided inside the second magnetic connector 14. The decorative lamp 15 is of a five-pointed star structure having an internal lighting source.

(10) Compared to the existing technology, the present disclosure drives the rotation of the transmission gear component 5 and the rotatable lamp through the drive motor 4, thereby causing the rotation of the decorative lamp 15, so that the decorative lamp 15 on the upper end of the Christmas tree can be lighted and rotated without rotating the entire Christmas tree, enhancing the fun of the product.

(11) The operating principle is as follows. The transmission shaft 6 is driven to rotate by the drive motor 4, and the transmission shaft 6 drives the upper gear 12 to rotate through the transmission gear component 5. Then, the rotation of the upper gear 12 drives the cylindrical sleeve member 9 to rotate, the rotation of the cylindrical sleeve member 9 drives the shaft sleeve 10 to rotate, the rotation of the shaft sleeve 10 drives the column body 13 to rotate, and the rotation of the column body 13 drives the decorative lamp 15 to rotate, whereby achieving the rotation of the decorative lamp 15 on the upper end of the Christmas tree.

(12) The above are preferred embodiments of the present disclosure merely and the present disclosure is not limited thereto. General changes and substitutions made within the scope of the technical solution of the present disclosure by those skills in the art are all intended to be included within the scope of protection of the present disclosure.
