[0021] The terms "up," "down," "left," "right," "front," "back," "front," "back," "top," and "bottom" mentioned or potentially mentioned in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may vary depending on their location or usage. Therefore, these or other directional terms should not be interpreted as restrictive. In addition, the terms "first," "second," "third," and similar expressions are used only for descriptive and distinguishing purposes and should not be understood to indicate or imply the relative importance of the corresponding components.

[0022] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0023] The embodiment of the present application discloses an adjustable lampshade.

[0024] An adjustable lampshade includes a base 1 and a light bulb. The base 1 is rotatably provided with a cover body 2. A convex tooth ring 21 is provided at the bottom of the cover body 2. The convex tooth ring 21 is fixedly connected to the cover body 2 by bolts. The convex tooth ring 21 has a first convex tooth 22. The base 1 is also rotatably provided with a drive shaft 12. The base 1 has a motor connected to the drive shaft 12. The upper end of the drive shaft 12 has a transmission gear 11. The transmission gear 11 meshes with the first convex tooth 22. The motor can drive the transmission gear 11 to rotate, and the transmission gear 11 can drive the cover body 2 to rotate. The cover body 2 has various hollow patterns. This figure is only a simple schematic. The light bulb can be projected onto the wall through the cover body 2. When the cover body 2 rotates, the pattern projected onto the wall will also rotate. This has a smart effect and a better sense of atmosphere.

[0025] The upper surface of the base 1 is defined by an annular groove 13, and the bottom of the cover 2 is provided with an annular protrusion 23 that fits within the groove 13. A ball bearing 14 is positioned at the bottom of the groove 13, against which the annular protrusion 23 abuts. This facilitates the rotation of the cover 2 on the base 1. The cover 2 is detachable, allowing replacement with different hollow shapes. The convex tooth ring 21 is detachable from the cover 2, and the modular design facilitates easy assembly of the cover 2.

[0026] The base 1 is also rotatably mounted with a light-blocking seat 3, which is fixed with a plurality of light-blocking bars 31. A second protruding tooth 32 is also fixed to the light-blocking seat 3, which meshes with the transmission gear 11. Rotation of the rotating gear also drives the light-blocking seat 3. The rotation of the light-blocking seat 3 also regularly blocks light, creating a rhythmic pattern and creating a sense of atmosphere. The light-blocking seat 3 is detachable from the base 1 and can be removed when not needed.

[0027] The base 1 is fixed with a socket 41, to which a color cover 4 is pluggably connected. The base 1 and color cover 4 are removable. The color cover 4 is made of a translucent plastic material and coated with a translucent color film, such as red, yellow, green, etc. The color of the color cover 4 can be projected by the bulb to match the color of the color cover 4.

[0028] A hand rope 5 is also fixed to the base 1 , one end of which passes through the cover 2 and is located above the cover 2 .

[0029] Generally, the base 1 is placed on a table. When a different cover 2 is needed, the cover 2 can be removed. When the lamp needs to be moved, the lamp can be lifted by the hand rope 5.

[0030] An iron sheet 6 is fixed to the bottom of the base 1 .

[0031] The present application can also be hung upside down on the ceiling, in which case the pattern can be projected onto the wall or floor. The specific installation method is to install a magnetic sheet on the roof, and the iron sheet 6 at the bottom of the base 1 is adsorbed to the magnetic sheet, so that the lampshade is inverted.

[0032] To prevent the inverted cover 2 from falling, a receiving slot 15 is provided in the base 1, and an anti-slip groove 16 is provided in the upper cover 2. An anti-slip column 17 is slidably mounted in the receiving slot 15, with one end of the anti-slip column 17 positioned within the anti-slip groove 16. A tension spring 18 is fixedly mounted on the wall of the receiving slot 15, one end of which is fixedly connected to the anti-slip column 17. The anti-slip column 17 prevents the cover 2 from separating from the base 1. To replace the cover 2 with a different hollowed-out pattern, simply remove one end of the anti-slip column 17 from the anti-slip groove 16.

[0033] The implementation principle of the embodiment is: the gear is rotated to drive the cover 2 to rotate, thereby rotating the pattern projected onto the wall, thereby creating a more atmospheric feeling.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation methods. Therefore, the above specific implementation methods and drawings are only illustrative descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction on the technical solution of the present invention. Therefore: All equivalent changes made in accordance with the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
