Technical Field

[0001] The utility model relates to the field of lampshades, in particular to a lampshade with an adjustable irradiation range. Background Art

[0002] A lampshade is a cover placed around the flame of a lamp or on the bulb to focus light or protect against wind and rain. The lampshade is not only placed on the lamp to gather light, but also prevents electric shock and protects the eyes. The lampshade is not only placed on the lamp to gather light, but also prevents electric shock and protects the eyes, so most lamps have lampshades.

[0003] When the lampshade is used, due to the requirements of the use occasion, for example, when studying or working at night, in order to avoid disturbing others, a smaller illumination range is usually required, while a larger illumination range is often required for normal use. Existing lampshades usually do not have the function of adjusting the illumination range. Therefore, a lampshade with an adjustable illumination range that solves the above problem is needed. Utility Model Content

The reflective cavity is installed on the inner side of the lower part of the lampshade body, and the lens sheet is installed on the lampshade body at the lower end of the reflective cavity. A threaded tube is slidably inserted into the upper part of the reflective cavity, and a guide groove is opened on the threaded tube. An internally threaded gear is rotatably embedded in the reflective cavity, and the internally threaded gear and the threaded tube are engaged, and a power gear is engaged on the internally threaded gear. A No. 1 motor is connected to the power gear, and the body of the No. 1 motor is connected to the reflective cavity. A diffusive plastic sheet is attached to the bottom of the lens sheet, and a transverse rotation structure is connected to the diffusive plastic sheet, and the transverse rotation structure is installed on the lampshade body.

[0006] Furthermore, the lateral rotation structure includes a No. 2 motor, a small gear, a large gear, and a rotating shaft. The No. 2 motor is fixedly installed inside the lampshade body, the small gear is fixedly installed on the output end of the No. 2 motor, the small gear is engaged with the large gear, the large gear is connected to the rotating shaft, the rotating shaft is rotatably installed outside the lampshade body and the lower end is fixedly connected to the diffusing plastic sheet.

[0009] Furthermore, the reflective cavity is a bowl-shaped structure with an inner wall coated with a diffuse reflection coating. Beneficial Effects

[0010] The utility model provides a lampshade with adjustable irradiation range, which has the following beneficial effects. Through its structural design, when the irradiation range needs to be adjusted, the No. 1 motor drives the power gear to rotate, and the rotation of the power gear drives the internal threaded gear to rotate. The rotation of the internal threaded gear drives the threaded tube restricted by the guide groove to move upward or downward, thereby driving the lamp connected to the lower end of the threaded tube to move upward or downward, thereby changing the distance between the lamp and the lens sheet, and realizing the change of the irradiation range. The reflective cavity reflects the lamp tubes irradiated on the four sides. When the irradiation range still needs to be increased, the astigmatism plastic sheet is driven to move to the bottom of the lens sheet through the lateral rotation structure, so that the light passing through the lens sheet is scattered, thereby further increasing the irradiation range, thereby solving the problem that the prior art is not convenient for adjusting the irradiation range of the light.
