Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a curtain rod. Background Art

[0002] Curtains are installed on the wall, window frame or ceiling through curtain rods. After the curtains are stretched along the curtain rods, the fabric can be completely hung on the window frame to prevent sunlight from entering the window, decorate the home, or serve as a stop.

[0003] To reduce transportation costs, curtain rods are typically constructed in sections and assembled at the construction site. These sectioned curtain rods are typically assembled using either threaded connections or expansion joints. Threaded connections, whether using connectors or directly connecting two rod sections by using different pipe diameters, require threads on the rod sections, which can affect the sliding of the curtains. Expansion joints, however, can reduce the strength of the connection due to their plastic material. Utility Model Content

[0004] In view of this, the utility model provides a curtain rod to solve the problem of unsmooth sliding of curtains.

[0005] The utility model provides a curtain rod, comprising a first curtain rod section, a second curtain rod section, a connecting pipe and a connecting piece.

[0006] A through hole is provided on a side wall of at least one of the first curtain rod section and the second curtain rod section.

[0007] A threaded hole is provided on the side wall of the connecting tube, and the two ends of the connecting tube are respectively connected to the first curtain rod section and the second curtain rod section. An opening is provided on the side wall of the connecting tube, and the opening is suitable for disconnecting the side wall of the connecting tube. The threaded hole corresponds to the position of the through hole.

[0008] The connecting piece is suitable for passing through the through hole and being connected to the threaded hole by threads. One end of the connecting piece located in the connecting pipe abuts against the inner wall of the connecting pipe, so that the connecting pipe can expand along the axial direction of the connecting piece.

[0009] Advantages: By plugging the ends of the connecting tube into the first and second curtain rod sections, respectively, and threading the connecting piece into the through-holes and threaded holes, the curtain rod sections can be quickly assembled and disassembled. Installation requires no complex tools or procedures, making it easy for users to adjust the curtain rod length or perform maintenance as needed. The connecting piece is threaded into the threaded hole of the connecting tube and engages with the through-holes of the curtain rod sections, effectively preventing loosening or falling off the connection and enhancing the stability and safety of the entire curtain rod. The expansion and fixation of the connecting tube by the connecting piece reduces friction and vibration between the rod sections caused by the curtain being pulled, thereby reducing noise and improving the user experience. If a component of the curtain rod is damaged, the modular design allows users to easily remove and replace the damaged component without having to replace the entire curtain rod, reducing maintenance costs and time. The connecting tube can be hidden inside the curtain rod, giving the entire curtain rod a more unified and aesthetically pleasing appearance without disrupting the overall interior decor. The smooth surface of the curtain rod also ensures smoother curtain movement.

[0010] In an optional embodiment, a plurality of the first curtain rod segments and the second curtain rod segments are provided, the plurality of the first curtain rod segments and the second curtain rod segments are alternately arranged, and adjacent first curtain rod segments and the second curtain rod segments are connected by the connecting pipe.

[0011] Benefits: By alternately arranging and connecting multiple rod sections, users can freely customize curtain rod lengths based on window dimensions and personal needs, achieving customized installation solutions. If a section or connecting tube within the curtain rod becomes damaged, the user can easily remove and replace the faulty component without affecting the functioning of other components. This modular design reduces maintenance costs and complexity, improving the system's maintainability.

[0012] In an optional embodiment, a connecting portion is provided on the side wall of the connecting pipe where the threaded hole is provided, and the threaded hole is provided on the connecting portion.

[0013] Beneficial effects: The provision of the connection portion provides additional support and fixing points, making the position of the threaded hole on the connecting pipe more stable, which can increase the strength of the threaded connection between the connector and the connecting pipe, and prevent loosening or falling off due to excessive force, thereby improving the stability and safety of the entire curtain rod. By specially providing a connection portion on the connecting pipe to carry the threaded hole, the overall structure of the connecting pipe can be made more reasonable and compact, avoiding structural weaknesses that may be caused by directly opening the threaded hole on the side wall of the connecting pipe, which is beneficial to improving the durability and service life of the connecting pipe. At the same time, the provision of the connection portion simplifies the processing process, making the processing and positioning of the threaded hole more accurate and convenient. At the same time, during the installation process, the user can more easily align and tighten the connector with the threaded hole on the connection portion, reducing the difficulty and time cost of installation.

[0014] In an optional embodiment, an abutment portion is provided on the side wall of the connecting pipe on the opposite side to the threaded hole, and the connecting member abuts against the abutment portion.

[0015] Beneficial Effects: The abutment provides an additional support point for the connector. When the connector is screwed into the threaded hole and tightened, it simultaneously abuts against the sidewall of the threaded hole and the abutment. This dual abutment effectively prevents the connector from loosening or slipping under load, thereby enhancing the connection stability between the connecting tube and the curtain rod section. The connector expands the connecting tube by abutting against the abutment, so the abutment helps distribute the tightening force applied by the connector more evenly across the connecting tube. This helps reduce localized stress concentration and improves the load-bearing capacity and service life of the connecting tube.

[0016] In an optional embodiment, the connecting pipe, the connecting portion and the abutting portion are constructed as an integrated structure.

[0017] Beneficial Effects: The integrated structure eliminates seams and connection points between different components, reducing potential weaknesses. This strengthens the connection between the connecting pipe, connecting portion, and abutting portion, resulting in higher overall strength and better resistance to external impact and stress. The integrated structure also simplifies the manufacturing process, reducing production costs and improving efficiency.

[0018] In an optional embodiment, the thickness of the connecting portion and the abutting portion is greater than the wall thickness of the connecting pipe.

[0019] Beneficial Effects: This enhances the structural strength of the connecting and abutting parts, making them more resistant to the tightening force applied by the connectors and preventing deformation or damage caused by stress concentration. It also helps improve the stability and durability of the connection, extending the service life of the curtain rod.

[0020] In an optional embodiment, the opening is arranged along the busbar direction of the connecting pipe.

[0021] Benefits: The busbar-directed opening allows the connecting tube to expand more smoothly along the axial direction when subjected to the connector, creating a closer contact with the curtain rod segment. This improves the sealing and stability of the connection while reducing stress concentration caused by uneven expansion.

[0022] In an optional embodiment, the opening is configured as a long strip structure.

[0023] Benefits: The opening of the long strip structure provides greater space and flexibility for the expansion of the connecting tube, making it better able to adapt to curtain rod sections of different diameters. This enhances the compatibility and adaptability of the connection, while also helping to improve the stability and durability of the connection.

[0024] In an optional embodiment, the connecting member is configured as a screw.

[0025] Benefits: Screws, as connectors, are simple, easily accessible, and offer strong fastening force. Through threaded connection, the screws fit tightly into the threaded holes in the connecting pipe and the through-holes in the curtain rod segments, achieving a secure connection. Furthermore, the screw's fastening force can be adjusted by rotating it to suit different installation requirements.

[0026] In an optional embodiment, the first curtain rod section abuts against the second curtain rod section.

[0027] Beneficial effect: There is no gap between the first curtain rod section and the second curtain rod section, thereby ensuring smoothness when the curtain slides. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 2 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, a curtain rod is provided, comprising: a first curtain rod section 1, a second curtain rod section 2, a connecting pipe 4 and a connecting piece.

[0036] A through hole 3 is provided on the side wall of at least one of the first curtain rod section 1 and the second curtain rod section 2. When connecting the first curtain rod section 1 and the second curtain rod section 2, it is necessary to ensure that there is at least one through hole 3 at the connecting position of the two to achieve the connecting function of the connector.

[0037] A threaded hole 5 is provided on the side wall of the connecting tube 4, and the two ends of the connecting tube 4 are respectively connected to the first curtain rod section 1 and the second curtain rod section 2. An opening 6 is provided on the side wall of the connecting tube 4, and the opening 6 is suitable for disconnecting the side wall of the connecting tube 4. The threaded hole 5 corresponds to the position of the through hole 3.

[0038] The connector is adapted to penetrate the through hole 3 and be connected to the threaded hole 5 by threads. One end of the connector located in the connecting tube 4 abuts against the inner wall of the connecting tube 4 so that the connecting tube 4 can expand along the axial direction of the connector.

[0039] In this embodiment, the connecting tube 4's two ends are plugged into the first and second curtain rod sections 1 and 2, respectively, and the connecting piece is threadedly connected to the through-hole 3 and threaded hole 5, enabling quick assembly and disassembly of the curtain rod sections. Installation requires no complex tools or procedures, making it easy for users to adjust the curtain rod length or perform maintenance as needed. The connecting piece is threadedly secured into the threaded hole 5 of the connecting tube 4 and engages with the through-hole 3 of the curtain rod section, effectively preventing loosening or falling off the connection and enhancing the stability and safety of the entire curtain rod. The expansion and fixation of the connecting tube 4 by the connecting piece reduces friction and vibration between the rod components caused by the curtain being pulled, thereby reducing noise and improving the user experience. If a component of the curtain rod becomes damaged, the modular design allows users to easily remove and replace the damaged component without having to replace the entire curtain rod, reducing maintenance costs and time. The connecting tube 4 can be concealed within the curtain rod, giving the entire curtain rod a more unified and aesthetically pleasing appearance without disrupting the overall interior decor. The smooth surface of the curtain rod also ensures smoother curtain movement.

[0040] In some embodiments, the connecting pipe 4 can be configured as a metal pipe to enhance the connection strength.

[0041] In some embodiments, the connecting pipe 4 can also be formed by extrusion of aluminum alloy. During production, a long pipe section is extruded at one time and then cut into small sections, which can greatly reduce production costs.

[0042] In some embodiments, multiple first curtain rod sections 1 and second curtain rod sections 2 are provided, multiple first curtain rod sections 1 and second curtain rod sections 2 are alternately arranged, and adjacent first curtain rod sections 1 and second curtain rod sections 2 are connected by connecting pipes 4.

[0043] In this embodiment, by alternately arranging and connecting multiple rod segments, users can freely customize the curtain rod length based on the actual window size and personal needs, achieving a customized installation solution. If a rod segment or connecting tube 4 in the curtain rod becomes damaged, the user can easily remove and replace the faulty component without affecting the normal operation of other parts. This modular design reduces maintenance costs and difficulty, and improves the maintainability of the system.

[0044] In some embodiments, the first curtain rod segment 1 and the second curtain rod segment 2 can be set to have the same structure, and a through hole 3 can be set on the rod segment. When connecting multiple curtain rod segments, the multiple curtain rod segments need to be connected end to end in sequence to allow the connecting piece to penetrate and act on the connecting tube 4.

[0045] In some embodiments, the first curtain rod segment 1 and the second curtain rod segment 2 can be set to have the same structure, and two through holes 3 can be set on the rod segment, and the two through holes 3 are respectively located at the two ends of the rod segment. When the through holes 3 are used to connect multiple curtain rod segments, the multiple curtain rod segments need to be connected end to end in sequence, and the through holes 3 are provided for the connecting parts to penetrate and act on the connecting tube 4.

[0046] In some embodiments, a connecting portion 7 is provided on the side wall of the connecting pipe 4 where the threaded hole 5 is provided, and the threaded hole 5 is provided on the connecting portion 7 .

[0047] In some embodiments, the number of threaded holes 5 on the connecting pipe 4 can be one or two. When two threaded holes 5 are provided on the connecting pipe 4 , the threaded holes 5 need to be provided at both ends of the connecting pipe 4 , respectively.

[0048] In this embodiment, the provision of the connection portion 7 provides additional support and fixing points, making the position of the threaded hole 5 on the connecting tube 4 more stable, increasing the strength of the threaded connection between the connector and the connecting tube 4, and preventing loosening or falling off due to excessive force, thereby improving the stability and safety of the entire curtain rod. By specifically providing a connection portion 7 on the connecting tube 4 to carry the threaded hole 5, the overall structure of the connecting tube 4 can be made more reasonable and compact, avoiding structural weaknesses that may be caused by directly opening the threaded hole 5 on the side wall of the connecting tube 4, which is conducive to improving the durability and service life of the connecting tube 4. At the same time, the provision of the connection portion 7 simplifies the processing process, making the processing and positioning of the threaded hole 5 more accurate and convenient. At the same time, during the installation process, the user can more easily align and tighten the connector with the threaded hole 5 on the connection portion 7, reducing the difficulty and time cost of installation.

[0049] In some embodiments, an abutment portion 8 is provided on the side wall of the connecting pipe 4 opposite to the side where the threaded hole 5 is provided, and the connecting piece abuts against the abutment portion 8 .

[0050] In this embodiment, the abutment 8 provides an additional support point for the connector. When the connector is screwed into the threaded hole 5 and tightened, it simultaneously abuts against the sidewall of the threaded hole 5 and the abutment 8. This dual abutment effectively prevents the connector from loosening or slipping when subjected to force, thereby enhancing the connection stability between the connecting tube 4 and the curtain rod section. The connector expands the connecting tube 4 by abutting against the abutment 8. Therefore, the provision of the abutment 8 helps to more evenly distribute the tightening force applied by the connector to the connecting tube 4. This helps to reduce local stress concentration and improve the load-bearing capacity and service life of the connecting tube 4.

[0051] In some embodiments, the connecting pipe 4 , the connecting portion 7 and the abutting portion 8 are constructed as an integral structure.

[0052] In this embodiment, the integrated structure eliminates seams and connection points between different components, thereby reducing potential weaknesses. This strengthens the connection between the connecting tube 4, the connecting portion 7, and the abutting portion 8, resulting in higher overall strength and better resistance to external impacts and stresses. The integrated structure also simplifies the manufacturing process, reducing production costs and improving production efficiency.

[0053] In some embodiments, the connecting portion 7 and the abutting portion 8 may be symmetrically arranged with respect to the length direction of the opening 6 , so that the connecting tube 4 can be expanded more smoothly.

[0054] In some embodiments, the axial direction of the threaded hole 5 may coincide with the diameter direction of the connecting tube 4 , so that the connecting tube 4 can be expanded more smoothly.

[0055] In some embodiments, the thickness of the connecting portion 7 and the abutting portion 8 is greater than the wall thickness of the connecting tube 4 .

[0056] In this embodiment, the structural strength of the connecting portion 7 and the abutting portion 8 is enhanced to better withstand the tightening force applied by the connector, preventing deformation or damage caused by stress concentration. This also helps to improve the stability and durability of the connection, extending the service life of the curtain rod.

[0057] In some embodiments, the connecting portion 7 and the abutting portion 8 may be spaced apart in the connecting tube 4 .

[0058] In some embodiments, the opening 6 is arranged along the generatrix direction of the connecting pipe 4 .

[0059] In this embodiment, the busbar-oriented openings 6 allow the connecting tube 4 to expand more smoothly along the axial direction when subjected to the connector, forming a closer contact with the curtain rod segment. This improves the sealing and stability of the connection while reducing stress concentration caused by uneven expansion.

[0060] In some embodiments, the direction of the opening 6 can be set to a corrugated structure or a zigzag structure.

[0061] In some embodiments, the opening 6 is configured as a long strip structure.

[0062] In this embodiment, the elongated opening 6 provides greater space and flexibility for the expansion of the connecting tube 4, enabling it to better adapt to curtain rod sections of different diameters, thereby enhancing the compatibility and adaptability of the connection and also helping to improve the stability and durability of the connection.

[0063] In some embodiments, the connecting member is configured as a screw.

[0064] In this embodiment, screws are used as connecting members, featuring a simple structure, easy accessibility, and strong fastening force. Through the threaded connection, the screws tightly engage the threaded holes 5 on the connecting tube 4 and the through-holes 3 on the curtain rod section, achieving a secure connection. Furthermore, the screw's fastening force can be adjusted by rotating it to suit different installation requirements.

[0065] In some embodiments, the first curtain rod section 1 abuts against the second curtain rod section 2 .

[0066] In this embodiment, there is no gap between the first curtain rod section 1 and the second curtain rod section 2 , thereby ensuring smoothness when the curtain slides.

[0067] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
