Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

In this embodiment 1, as shown in fig. 1, fig. 2 and fig. 3, a lampshade capable of adjusting light intensity includes a lampshade 1, the exterior of the lampshade 1 is in a horn-shaped structure, and the diameter of the upper end of the lampshade 1 is smaller than that of the lower end, so as to have a good aesthetic effect, an annular frame 4 is disposed inside the lampshade 1, an annular groove 3 corresponding to the annular frame 4 is disposed on the inner wall of the lampshade 1, an annular rack 2 is slidably connected in the annular groove 3, the annular rack 2 is fixedly connected to the outer side wall of the annular frame 4, a plurality of support rods 6 are fixedly connected to the inner wall of the lampshade 1, the other end of each support rod 6 is fixedly connected to a vertically disposed stop rod 5, a shielding mechanism is disposed on the inner wall of the annular frame 4, a driving cavity 8 is disposed on one side of the annular groove 3, the number of the stop rods 5 and the number, the driving mechanism is arranged in the rotating groove 9, the annular frame 4 can rotate through the driving mechanism, and therefore the light passing range of the light shading mechanism to the light is reduced, and the illumination intensity is reduced.

The specific arrangement and operation of the drive mechanism will be described in detail below.

As shown in fig. 1, the driving mechanism includes a driving rod 10 located inside the rotating groove 9, the upper end of the driving rod 10 extends to the outside of the rotating groove 9 and is fixedly connected with a turntable 12, an outlet fixedly connected with rotating part 11 is arranged on the rotating groove 9, the driving rod 10 is rotatably connected inside the rotating part 11, the lower end of the driving rod 10 extends to the inside of the driving cavity 8 and is fixedly connected with a gear 7, and the gear 7 is meshed with the annular rack 2.

The motion principle and the achieved effect of the whole driving mechanism are as follows: the rotating disc 12 is rotated, so that the driving rod 10 rotates, the driving rod 10 drives the gear 7, the rotating gear 7 drives the annular rack 2 to rotate, and the annular frame 4 rotates.

As shown in fig. 1, the shielding mechanism includes a plurality of rotating rods 14 rotatably connected inside the annular frame 4, the rotating rods 14 are in contact with the blocking rod 5, a shielding cloth 13 is fixedly connected between the rotating rods 14 and the inner wall of the annular frame 4, and a spring 15 is fixedly connected between the rotating rods 14 and the annular frame 4.
