[0002] In the existing rolling curtain system, the support rod plays a crucial role. It not only provides the necessary structural support for the rolling curtain but also ensures the smooth lifting and correct positioning of the rolling curtain fabric.

[0003] However, the conventional rolling curtain support rods are of standard sizes. Due to the diversity of building sizes and design requirements, the standard-sized support rods often cannot directly meet the requirements of all installation scenarios. Therefore, on-site workers need to cut and adjust the support rods according to the actual sizes of windows or doors. This process is not only time-consuming and laborious but also may affect the appearance and performance of the rolling curtain system due to inaccurate measurement or cutting.

Specific embodiments[[ID=2^]]

[0028] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] Please refer to Figures 1 to 8 , for the spliced rolling curtain support rod of an embodiment of the present invention, including at least two support rods 10 arranged in a coaxial and co-directional array, and a connection component 20 that is connected to match between adjacent support rods 10.

[0032] A first through hole 11 is provided at one end of the support rod 10, and a second through hole 12 is provided at the other end of the support rod 10. The axial direction of the second through hole 12 is perpendicular to the axial direction of the first through hole 11; the first through hole 11 and the second through hole 12 are both used to match and connect the docking assembly 20.

[0033] Furthermore, one end of the support rod 10 has an embedded portion 13, and the other end of the support rod 10 is provided with a slot 14 along its length, which runs from one side of the support rod 10 to the other side of the support rod 10. Among them, the first through hole 11 passes through the embedded portion 13, and the second through hole 12 passes through the slot 14.

[0034] Specifically, the embedded portion 13 is non-circular, for example, in the present embodiment, the embedded portion 13 is rectangular; understandably, in other embodiments, the embedded portion 13 can also be triangular, pentagonal or hexagonal or other non-circular shapes, as long as it can prevent slipping.

[0035] The connecting assembly 20 includes an inner sleeve 21, a first fixing pin 22 and a second fixing pin 23 extending through opposite ends of the inner sleeve 21, and an outer sleeve 24 coaxially extending outside the inner sleeve 21. One end of the inner sleeve 21 is fitted with a support rod 10, while the other end of the inner sleeve 21 is fitted with another support rod 10. The first fixing pin 22 and the second fixing pin 23 are inserted through the inner sleeve 21 and then into the first through-hole 11 and the second through-hole 12, respectively, to achieve a fixed connection between the inner sleeve 21 and the two support rods 10.

[0036] Specifically, a first embedding hole 25 is defined within one end of the inner sleeve 21, and a second embedding hole 26 is defined within the other end of the inner sleeve 21. The first embedding hole 25 is used to insert one support rod 10, and the second embedding hole 26 is used to insert another support rod 10. Furthermore, a first through hole 27 is defined at one end of the inner sleeve 21, and a second through hole 28 is defined at the other end of the inner sleeve 21. The first through hole 27 extends through the first embedding hole 25, and the second through hole 28 extends through the second embedding hole 26.

[0037] During actual assembly, the first embedding hole 25 is used to accommodate the embedding part 13 of a support rod 10. The first through hole 27 corresponds to the first through hole 11. The first fixing pin 22 is passed through the first through hole 27 and the first through hole 11 to realize the fixed connection between the inner shaft sleeve 21 and a support rod 10. At the same time, the second embedding hole 26 is used to accommodate another support rod 10. The second through hole 28 corresponds to the second through hole 12. The second fixing pin 23 is passed through the second through hole 28 and the second through hole 12 to realize the fixed connection between the inner shaft sleeve 21 and another support rod 10. Thus, the coaxial connection between the inner shaft sleeve 21 and the two support rods 10 is realized. Finally, the outer shaft sleeve 24 is sleeved outside the inner shaft sleeve 21 to prevent the first fixing pin 22 and the second fixing pin 23 from loosening, ensuring the completion of the splicing between two adjacent support rods 10. At the installation site, multiple different support rods 10 can be quickly and accurately spliced according to different installation requirements, thereby reducing the time for on-site measurement and cutting and improving the overall installation efficiency.

[0038] Specifically, in this embodiment, the shape of the first embedding hole 25 completely matches the shape of the embedding part 13. The second embedding hole 26 is generally arranged in a butterfly shape. Wedge-shaped protrusions 260 are respectively provided on the opposite inner walls of the inner shaft sleeve 21 corresponding to the second embedding hole 26, and the wedge-shaped protrusions 260 are fitted and clamped on the opposite sides of the slotted groove 14.

[0039] In this embodiment, notches 241 are respectively provided on the opposite sides of one end of the outer shaft sleeve 24, and clamping feet 242 are respectively connected to the opposite sides of the other end of the outer shaft sleeve 24. Among them, the notches 241 and the clamping feet 242 are used to connect the spring box structure 29, and the spring box structure 29 is connected in series to the support rod 10.

[0040] The above-mentioned spliced rolling shutter support rod has a simple structure and is convenient to use. The inner shaft sleeve 21 and the outer shaft sleeve 24 cooperate, and the inner shaft sleeve 21 and the support rod 10 are connected by the first fixing pin 22 and the second fixing pin 23. Multiple support rods 10 can be quickly and accurately spliced according to different installation requirements, thereby reducing the time for on-site measurement and cutting and improving the overall installation efficiency.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
