[0002] Greenhouse, also known as warm house, is a facility that can let in light and keep warm, used to grow plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, appearance and heating conditions.

[0003] When a greenhouse is in use, two layers of covering film are often provided for the color change and adjustment of sunlight. However, the distance between the two layers of existing covering film is fixed and cannot be adjusted in time according to the sunlight height. A color change and scattering double film structure for greenhouses is now proposed. Utility Model Content

[0024] In the embodiment of the utility model, the arc frame 32 can move up and down through the cooperation of the positioning rod 35 and the positioning hole 34, and further drives the entire inner bracket 3 to move up and down.

[0025] Specifically, a motor 51 is fixedly mounted on the surface of the bottom plate 5 , a transmission rod 52 is fixedly connected to the output end of the motor 51 , and a film-collecting roller 53 is fixedly mounted on the surface of the transmission rod 52 .

[0026] In the embodiment of the utility model, the motor 51 is arranged to rotate the transmission rod 52 so that the film collection roller 53 can retract the inner film 4 .

[0027] Specifically, a first bevel gear 54 is fixedly mounted on the surface of the transmission rod 52, a fixed block 55 is fixedly mounted on the surface of the base plate 5, a rotating bracket 56 is rotatably connected inside the fixed block 55, a second bevel gear 57 is fixedly mounted on one end of the rotating bracket 56, the first bevel gear 54 is meshed with the second bevel gear 57, a screw sleeve 36 is threadedly connected to the surface of the rotating bracket 56, and the other end of the screw sleeve 36 is fixedly connected to the surface of the positioning rod 35.
