Description

Full-shading roller shutter Technical Field The invention relates to the technical field of manufacturing of electric curtains, in particular to a full-shading roller shutter. Background The curtain is a common ornament, has the functions of shading sun, insulating heat and regulating indoor light, has various types, is increasingly applied to outdoor sunlight rooms along with the continuous improvement of the requirements of people on the standard of household life, is built by glass and metal frames, and can irradiate sunlight no matter a roof or four walls, so that the roof and the four walls of the sunlight rooms are also provided with the shading curtain, and when a user wants to let a brightness dark spot indoors, the shading curtain can be pulled to meet the requirements of people on different intensities of the light, and the requirements of different application scenes of the user are met. Such as the chinese patent application number CN202421728117.7, patent title is an electric honeycomb sunshade. It is provided with an adjusting structure, when all the two-shaft motors are required to be opened, the two-shaft motors are started, the rotary rod is rotated, so that the second fixing rod is driven to move upwards, and the technical effect of complete opening is achieved. However, only one honeycomb sunshade curtain body is put down to shade sun, and part of light irradiates in, so that the whole indoor shading can not be realized. For example, the patent title of the retractable electric sunshade curtain is CN202420080834.7, and the retractable electric sunshade curtain comprises a window frame and a sunshade curtain body. The technical effect of the invention that the invention has the advantage of being adjustable according to the size of the window is achieved. However, the sunshade curtain body is also only one, namely, the sunshade curtain body is completely put down to shade sun, and partial light irradiates into the sunshade curtain body, so that the whole indoor shading can not be realized. Therefore, the existing electric curtains are basically single-piece sun shades, and realize limited shading by moving up and down. With the development of personalization of users, in some application scenarios (such as private cinema or sleeping), there is a high requirement for indoor brightness, and no residual light can be taken in, so there is a need in the market for a curtain capable of blocking external light. Disclosure of Invention The present invention is directed to a roller blind for solving the above-mentioned problems. In order to solve the technical problems, the invention provides a full-shading roller shutter, which comprises a first curtain assembly capable of moving a first shading curtain from top to bottom, and is characterized in that a second curtain assembly capable of moving a second shading curtain from bottom to top is arranged on the full-shading roller shutter, the second curtain assembly and the first curtain assembly can independently shade sun, the second curtain assembly comprises a curtain rotating module serving as a main body, side rail assemblies are arranged on two sides of the curtain rotating module, and the other end of the side rail assembly is fixedly connected with the first curtain assembly. Compared with the prior art, the novel structure has the advantages that on the basis of the existing first curtain assembly, the independent second curtain assembly is additionally arranged, the first sunshade curtain of the first curtain assembly runs from top to bottom, the second sunshade curtain of the second curtain assembly runs from bottom to top, double shading is realized, external light is prevented from being irradiated into a room, and the indoor full shading effect is realized. As an improvement of the invention, the side rail assembly comprises a side rail, a pull rope assembly is arranged on the side rail, the pull rope assembly comprises a first pull rope upper fixing module, a tension spring is connected to the first pull rope upper fixing module, the other end of the tension spring is connected with a pull rope tensioner module, the pull rope tensioner module is connected with a second pull rope upper fixing module through one end of a roller shutter pull rope, the pull rope tensioner module is connected with a pull rope lower fixing module through the other end of the roller shutter pull rope, the pull rope lower fixing module is connected with a lifting curtain fixing module through the roller shutter pull rope, and the lifting curtain fixing module is fixedly connected with a lifting beam rod (the lifting beam rod is connected with a second sunshade curtain). The roller shutter curtain is characterized in that the roller shutter curtain comprises a first pull rope upper fixing module, a second pull rope upper fixing module, a pull rope tensioner module and a pull rope lower fixing module, wherein the first pull rope upper fixing module is used for f
