Description

Technical Field

[0001] The present application relates to the technical field of curtains, and in particular to roller blinds. Background Art

[0002] Roller curtains, also known as roll-up curtains, are named after the fact that they are driven by a roller tube to roll up and down, compared to traditional fabric curtains that open and close left and right. They are widely used in formal occasions such as offices, office buildings, banks, and schools. At present, they can be divided into bead-type roller curtains, spring-type roller curtains, and electric roller curtains according to different operating methods. In order to increase the shading and stability of roller curtains, existing roller curtains are usually equipped with side rails. For example, the patent "A Windproof Roller Curtain Window" with publication number CN214787112U has a shading slot assembly as a side rail.

[0003] However, existing roller blinds with rails generally have problems such as complex structure, inconvenient assembly, high cost, short service life, etc. In addition, with the continuous development of the e-commerce economy, the transportation convenience and assembly simplicity of roller blinds are becoming more and more important.

[0004] Therefore, how to improve the existing rolling curtains to overcome the above problems is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] One purpose of the present application is to provide a modular and universal roller blind with a track which has a simple structure, is easy to assemble, has a long service life and has a good shading effect.

[0006] To achieve the above purpose, the technical solution adopted in the present application is as follows: a roller shutter with rails comprises: a full-cover shell assembly, a side rail assembly, a lower rail assembly, a connecting bracket assembly, a spring roller shutter assembly and a driving assembly; the side rail assembly has two groups, the full-cover shell assembly, the side rail assembly and the lower rail assembly are fixedly connected by the connecting bracket assembly to form a rectangular frame, the spring roller shutter assembly comprises a roller shutter assembly and a roller shutter, the roller shutter assembly is installed on the connecting bracket assembly and is located in the full-cover shell assembly, the roller shutter is wound on the roller shutter assembly and is suitable for passing through the full-cover shell assembly, and the driving assembly is suitable for driving the spring roller shutter assembly to move so that the roller shutter moves up and down to open or cover the rectangular frame;

[0007] The fully enclosed cover shell assembly includes a face cover shell and a back cover shell, wherein the face cover shell and the back cover shell are L-shaped profiles, and the face cover shell and the back cover shell are butted together to form a fully enclosed installation cavity, and a curtain outlet for the roller blind to pass through is provided below the installation cavity;

[0071] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0072] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0073] like Figures 1 to 21 As shown, the preferred embodiment 1 of the present application includes a full-enclosed housing assembly 1, a side rail assembly 2, a lower rail assembly 3, a connecting bracket assembly 4, a spring roller shutter assembly 5, a manual drive assembly 6 and an installation fixing buckle 7; the side rail assembly 2 has two groups, the full-enclosed housing assembly 1, the side rail assembly 2 and the lower rail assembly 3 are fixedly connected by the connecting bracket assembly 4 to form a rectangular frame, the spring roller shutter assembly 5 includes a roller shutter assembly 51 and a roller shutter 52, the roller shutter assembly 51 is installed on the connecting bracket assembly 4 and is located in the full-enclosed housing assembly 1, the roller shutter 52 is wound on the roller shutter assembly 51 and is suitable for passing through the full-enclosed housing assembly 1, and the manual drive assembly 6 is suitable for driving the spring roller shutter assembly 5 to move, so that the roller shutter 52 moves up and down, which is used to open or cover the rectangular frame. The above seven parts are described in detail below:

[0074] Full enclosure assembly 1:

[0075] like Figures 5 to 9 As shown, the full-enclosed cover shell assembly 1 includes a face cover shell 11 and a back cover shell 12. The face cover shell 11 and the back cover shell 12 are profiles with an L-shaped cross-section. The face cover shell 11 and the back cover shell 12 are connected to form a full-enclosed installation cavity 1a, and a curtain outlet 1b is opened below the installation cavity 1a for the roller blind 52 to pass through.

[0076] like Figure 5As shown, the mask shell 11 and the back shell 12 are docked through a male buckle 13 and a female buckle 14. The male buckle 13 includes a first vertical plate 131 and a first buckling plate 132. The female buckle 14 includes a second vertical plate 141 and a second buckling plate 142. Both the first vertical plate 131 and the second vertical plate 141 extend in the up and down direction. The first buckling plate 132 is in an "L" - shaped structure and is arranged at the head end of the first vertical plate 131. The second buckling plate 142 is in a "C" - shaped structure and is arranged at the tail end of the second vertical plate 141. The second buckling plate 142 and the second vertical plate 141 surround to form a clamping groove 14a. As Figure 6 and Figure 7 shown, the first buckling plate 132 is adapted to be obliquely inserted into the clamping groove 14a. By rotating and moving the male buckle 13 downward, the second buckling plate 142 is elastically deformed, so that the first buckling plate 132 falls into the clamping groove 14a in the up and down direction. The above structure enables the mask shell 11 and the back shell 12 to form a fully enclosed structure through clamping, which has the advantages of convenient processing, simple assembly, reliable structure and low cost. In this embodiment, the mask shell 11 and the male buckle 13 are integrally extruded and formed, and the back shell 12 and the female buckle 14 are integrally extruded and formed.

[0077] Further, as Figure 8 and Fig. 9 shown, the outer sides of the first vertical plate 131 and the first buckling plate 132 are smoothly connected. The thickness of the first vertical plate 131 is H1, the thickness of the horizontal part of the first buckling plate 132 is J1, and the length of the horizontal part of the first buckling plate 132 is K1; the thickness of the second vertical plate 141 is H2, the vertical interval between the second vertical plate 141 and the second buckling plate 142 is J2, and the horizontal interval between the second vertical plate 141 and the second buckling plate 142 is K2; H1 = H2 = K1 = K2, J1 = J2, and J1 = a·H1, 1.1 ≤ a ≤ 1.4. The above parameter settings make the clamping of the male buckle 13 and the female buckle 14 more fitting, eliminate the gap when they are clamped, and make the overall structure of the fully enclosed shell assembly 1 more stable and reliable.
