Description

Technical Field

[0001] This utility model relates to the field of roller shutter tube technology, specifically a roller shutter tube splicing structure. Background Technology

[0002] With the increasing demands of modern buildings and industrial equipment, roller shutters, as a highly flexible and adaptable material, are widely used in various fields such as machinery, construction, security, and industry. Especially in situations requiring rapid assembly and disassembly, roller shutters have gained widespread application due to their superior variability and efficiency. However, existing roller shutter splicing structures have certain limitations, mainly manifested in complex assembly processes, cumbersome connection methods, and long construction cycles.

[0003] Traditional roller shutter tube splicing structures typically rely on multiple curved connectors and complex operating steps, resulting in a large workload and low efficiency during the assembly process.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a roller shutter tube splicing structure. Utility Model Content

[0005] The purpose of this invention is to provide a roller shutter tube splicing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A technical solution for a roller shutter tube splicing structure includes a roller shutter tube one and a roller shutter tube two. The roller shutter tube one and the roller shutter tube two are detachably connected by a left arc-shaped connector and a right arc-shaped connector. A connecting cavity is formed between the left arc-shaped connector and the right arc-shaped connector. A roller shutter tube limiting strip is provided in the connecting cavity. The left arc-shaped connector and the right arc-shaped connector are fixed by a V-shaped wedge and locked by screws.

[0008] As a preferred technical solution, the cross-sections of the left and right arc-shaped connectors are symmetrical arc-shaped structures, and the dimensions of the connecting cavity match the outer diameters of the ends of roller shutter tube one and roller shutter tube two.

[0009] As a preferred technical solution, the roller shutter tube limiting strip is distributed along the outer wall of the left arc-shaped connector and the right arc-shaped connector to limit the circumferential displacement of roller shutter tube one and roller shutter tube two.

[0010] As a preferred technical solution, the end of the screw is provided with an anti-loosening washer, and its threaded portion engages with a V-shaped wedge.

[0011] As a preferred technical solution, the inner surfaces of the left and right arc-shaped connectors are provided with reinforcing ribs, which are evenly distributed along the circumference of the connecting cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a roller shutter tube splicing structure. It features left and right arc-shaped connectors, and V-shaped wedges that utilize screws for tightening and expansion to compress and fix the left and right arc-shaped connectors to the roller shutter tube. This significantly simplifies the assembly process, reduces the number of connectors used, lowers the complexity of the operation steps, and thus shortens the construction cycle. Furthermore, the symmetrical arc-shaped cross-sections of the left and right arc-shaped connectors match the outer diameter of the roller shutter tube's end, improving the stability and sealing of the connection. The roller shutter tube limiting strip effectively restricts the circumferential displacement of the roller shutter tube, enhancing the stability of the splicing structure. The anti-loosening washer design at the screw end prevents bolt loosening, improving connection safety. The reinforcing ribs on the inner surfaces of the left and right arc-shaped connectors enhance the strength and rigidity of the arc-shaped connectors, extending the service life of the splicing structure.

[0019] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution for a roller shutter tube splicing structure: it includes a first roller shutter tube 11 and a second roller shutter tube 12, as well as a connecting assembly for connecting the two roller shutter tubes. The connecting assembly includes a left arc-shaped connector 21, a right arc-shaped connector 22, a V-shaped wedge 25, a screw 26, and a roller shutter tube limiting strip 24. The left arc-shaped connector and the right arc-shaped connector are fixed by the V-shaped wedge and locked by the screw, thereby realizing a detachable connection between the first roller shutter tube and the second roller shutter tube.

[0021] In practical implementation, the cross-sections of the left and right arc-shaped connectors are designed as symmetrical arc structures to ensure matching with the outer diameters of the ends of roller shutter tube one and roller shutter tube two, thereby providing good connection stability and sealing. The dimensions of the connecting cavity 23 match the outer diameters of the ends of roller shutter tube one and roller shutter tube two to ensure a good fit between the arc-shaped connectors and the roller shutter tubes.

[0022] Roller shutter tube limiting strips 24 are distributed along the outer walls of the left arc-shaped connector 21 and the right arc-shaped connector 22 to limit the circumferential displacement of roller shutter tube 11 and roller shutter tube 22, ensuring the stability of the spliced ​​structure. The end of the screw 26 is provided with an anti-loosening washer, and its threaded part cooperates with the V-shaped wedge 25 to prevent the bolt from loosening and improve the safety of the connection.

[0023] The inner surfaces of the left arc-shaped connector 21 and the right arc-shaped connector 22 are provided with reinforcing ribs (not shown in the figures). These reinforcing ribs are evenly distributed along the circumference of the connecting cavity to enhance the strength and rigidity of the arc-shaped connectors and extend the service life of the splicing structure.

[0024] During assembly, the ends of roller shutter tube 11 and roller shutter tube 22 are first inserted into the connecting cavities of the left arc-shaped connector 21 and the right arc-shaped connector 22. Then, the left arc-shaped connector 21 and the right arc-shaped connector 22 are fixed together by the V-shaped wedge 25. Afterwards, the V-shaped wedge 25 is tightened and expanded using screws 26, achieving compression and fixation of the left and right arc-shaped connectors to the roller shutter tubes, greatly simplifying the assembly process and ensuring the stability and safety of the entire splicing structure. The roller shutter tube limiting strip plays a positioning role during assembly, preventing circumferential displacement of the roller shutter tube during use.

[0025] Through the above embodiments, the roller shutter tube splicing structure of this utility model not only simplifies the assembly process, reduces the number of connectors used, and reduces the complexity of operation steps, but also improves the stability and safety of the connection and extends the service life of the splicing structure.

[0026] The working principle and usage process of this utility model: After assembling the various components of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
