Description

Technical Field

[0001] This utility model relates to the technical field of curtain rods, and in particular to a curtain rod. Background Technology

[0002] A curtain rod is a decorative rod used to hang curtains. A curtain rod consists of a main rod and a secondary rod. The curtain fabric that fits the curtain rod is bent and sewn to form a fitting hole. The size of the fitting hole is adapted to the secondary rod. The main rod is bent inward to form a mounting hole for the secondary rod to fit into. The end face of the curtain fabric away from the secondary rod is fitted against the inner wall of the mounting hole, so that the curtain fabric can be rolled up on the curtain rod by rotating the curtain rod.

[0003] In the existing technology, when the curtain rod is long, the main rod is usually transported in sections, and adjacent sections are connected by a connector. However, in actual application, it has been found that the connector used to connect adjacent sections is mostly fixed to the main rod with bolts. After long-term use, the curtain fabric at the bolts will rub and deform, affecting the service life and appearance of the curtain fabric. Utility Model Content

[0004] In order to extend the service life of the curtain fabric that is used with the curtain rod, this application provides a curtain rod.

[0005] This application provides a curtain rod that adopts the following technical solution:

[0006] A curtain rod includes a main rod, a fixed base, and a rotating base. The fixed base and the rotating base are respectively disposed at both ends of the main rod. The main rod includes multiple rod body sections and connectors for connecting adjacent rod body sections. The connectors include limiting portions and connecting portions symmetrically disposed on both sides of the limiting portions. Each rod body section has a corresponding connecting cavity for the connecting portions to fit into. The shape of the limiting portion is consistent with the cross-section of the rod body section. The connecting portion has a fixing member for fixing the rod body section. The sidewall of the rod body section is recessed in the direction of the rod body section axis to form a fitting portion and a clearance portion. The fitting portion cooperates with a secondary rod disposed on the curtain fabric, and the clearance portion is used to accommodate the fixing member.

[0007] By adopting the above technical solution, the fixing parts used to fix the connectors and the rod body are housed in the clearance part. In actual application, the curtain fabric can only contact the outer wall of the main rod, which reduces the friction and deformation of the curtain fabric caused by the fixing parts and can extend the service life of the curtain fabric to a certain extent.

[0008] Preferably, the fixing member includes a fixing bolt, the rod body has a through hole for the fixing bolt to pass through, the connecting part has a fixing hole that mates with the fixing bolt, and when the rod body moves to fit against the limiting part, the through hole and the fixing hole communicate with each other.

[0009] By adopting the above technical solution, the rod body is fixed to the connecting parts by fixing bolts, which facilitates operation.

[0010] Preferably, the fastener further includes a fixing rivet disposed on the connecting portion on any side of the limiting portion, the rod body is provided with a mounting through hole for the fixing rivet to pass through, and the connecting portion is provided with a mounting hole that is interference-fitted with the fixing rivet.

[0011] By adopting the above technical solution, the fixing rivets and mounting holes are interference-fitted, so that the connector and the corresponding rod body form an unremovable connection, which improves the reliability of fixing the connector and the rod body. Before the curtain rod is transported, the connector located on either side of the limiting part needs to be fixed to the rod body by fixing rivets. Then, at the curtain rod installation site, the operator only needs to fix the other end of the rod body to the rod body by fixing bolts, which facilitates the assembly of the curtain rod.

[0012] Preferably, the fixed seat is rotatably connected to a fixing part that mates with the connecting cavity, the rotating seat is rotatably connected to a ball wheel, the rotating seat is slidably connected to a pull bead for controlling the rotation of the ball wheel, the ball wheel is coaxially provided with a stop head that mates with the connecting cavity, and the outer peripheral walls of the fixing part and the stop head are both provided with fixing strips that fit against the inner wall of the connecting cavity.

[0013] Preferably, both the fixed seat and the rotating seat are rotatably connected to a positioning part that mates with the connecting cavity. The positioning part is provided with a clearance groove for the fitting part and the clearance part to engage. The positioning part that mates with the fixed seat is coaxially provided with a rotating column. The fixed seat is provided with a rotating through hole for the rotating column to engage.

[0014] The rotating seat is coaxially provided with an irregularly shaped rotating pin, the positioning part is provided with a pin through hole that cooperates with the rotating pin, and the rotating seat is provided with a rotating component for driving the rotating pin to rotate.

[0015] Preferably, the rotating component includes a meshing worm gear and a worm, and the rotating seat is provided with a cover for accommodating the worm gear and the worm. The worm gear and the worm are both rotatably disposed in the cover, the rotating pin is coaxially disposed on the worm gear, and the end of the worm facing the ground is provided with a rotating pull ring.

[0016] By adopting the above technical solution, the main rod in this application can be used for two rotation methods. When the rotation of the main rod is achieved by pulling the bead, the production cost of the fixed seat and the rotating seat is effectively reduced, and it is also easy to operate in actual use, with a high cost performance. When the rotation of the main rod is achieved by rotating the pull ring to drive the worm gear, the safety of children during the use of the curtain rod is effectively improved, and the simplicity of the room can be improved to a certain extent.

[0017] Preferably, the fitting portion and the avoidance portion are symmetrically arranged on both sides of the radial direction of the rod body.

[0018] The above technical solution facilitates the processing of the main body and reduces manufacturing difficulty.

[0019] Preferably, the end of the connecting portion away from the limiting portion is provided with a guide slope.

[0020] By adopting the above technical solution and setting the guide slope, the connecting part is easily embedded in the connecting cavity, which facilitates the assembly of the curtain rod and improves the assembly efficiency of the curtain rod to a certain extent.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. If the fasteners used to fix the connectors and the rod body are housed in the clearance part, then in actual application, the curtain fabric can only contact the outer wall of the main rod, which reduces the friction and deformation of the curtain fabric caused by the fasteners and can extend the service life of the curtain fabric to a certain extent.

[0023] 2. Before transporting the curtain rod, the connecting part on either side of the limiting part must be fixed to the rod body using fixing rivets and fixing bolts. Then, at the installation site, the operator only needs to fix the other end of the rod body to the rod body using fixing bolts, which reduces the assembly difficulty of the curtain rod and facilitates the assembly of the curtain rod.

[0024] 3. The main rod in this application can be used for two rotation methods. When the rotation of the main rod is achieved by pulling the bead, the production cost of the fixed seat and the rotating seat is effectively reduced. It is also easy to operate in actual use and has a high cost performance. When the rotation of the main rod is achieved by rotating the pull ring to drive the worm gear, the safety of children during the use of the curtain rod is effectively improved, and the simplicity of the room can be improved to a certain extent.

[0033] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0034] Example 1:

[0035] This application discloses a curtain rod, as shown in the embodiments below. Figure 1 and Figure 2 The curtain rod includes a main rod 1, which comprises multiple rod sections 11 and connectors 12 for fixing adjacent rod sections 11. The actual number of rod sections 11 depends on the actual length of the curtain rod, facilitating the transportation of longer curtain rods. In this embodiment, two rod sections 11 are selected as an example. The rod sections 11 are made of stainless steel, thus possessing good strength, durability, and corrosion resistance, and can withstand significant weight. They are less prone to damage when used to hang heavy curtains, thereby extending the service life of the curtain rod to a certain extent.

[0036] Reference Figure 2 The connector 12 includes a limiting part 121 and connecting parts 122 symmetrically arranged on both sides of the limiting part 121. The connecting parts 122 and the limiting part 121 are integrally formed. The rod body 11 is provided with a corresponding connecting cavity 111 for the connecting parts 122 to fit into. The connecting parts 122 can move along the connecting cavity 111 until the limiting part 121 fits into the rod body 11, so that the shape of the limiting part 121 is consistent with the cross-section of the rod body 11, ensuring the integrity and aesthetics of the curtain rod after assembly.

[0037] Reference Figure 2The sidewall of the rod body 11 is recessed towards the axis of the rod body 11 to form a fitting part 112 and a clearance part 113. The fitting part 112 cooperates with the auxiliary rod provided on the curtain fabric, so that the curtain fabric can be stored on the main rod 1 when the main rod 1 rotates, realizing the raising and lowering of the curtain fabric. The connecting part 122 is provided with a fixing member for fixing the rod body 11, and the clearance part 113 is used to store the fixing member. When the curtain fabric is stored by the main rod 1, the curtain fabric is less likely to come into contact with the fixing member, effectively reducing the wear and tear of the curtain fabric during actual use and extending the service life of the curtain fabric. The fitting part 112 and the clearance part 113 are symmetrically arranged on both sides of the radial direction of the rod body 11, which facilitates the processing of the main rod 1 body in actual operation and reduces the manufacturing difficulty.

[0038] The transition between the rod body 11, the fitting part 112 and the avoidance part 113 are all arc-shaped. The arc shape makes it less likely for the curtain rod to wear down the curtain fabric during actual use, effectively extending the service life of the curtain fabric. In addition, the assembler is less likely to be injured during the actual assembly process, making it safer.

[0039] Reference Figure 2 The fastener includes a fixing bolt 13. A through hole 114 for the fixing bolt 13 is provided on the rod body 11. A fixing hole 123 mates with the fixing bolt 13 on the connecting part 122. When the rod body 11 moves to fit against the limiting part 121, the through hole 114 communicates with the fixing hole 123. It should be noted that the connecting part 12 in this application is made of plastic, effectively reducing the cost of using the curtain rod. The connecting part 12 can be injection molded separately or directly injection molded at one end of the rod body 11. In this embodiment, the connecting part 12 is injection molded separately. The fixing bolt 13 in this application can be a regular bolt or an expansion bolt. When the fixing bolt 13 is a regular bolt, a pre-embedded part that mates with the thread of the fixing bolt 13 needs to be reserved during the injection molding process of the connecting part 12 to facilitate the fixing of the connecting part 12 to the rod body 11. In this embodiment, the fixing bolt 13 is an expansion bolt.

[0040] Reference Figure 2The fastener includes a fixing rivet 14 disposed on the connecting part 122 on either side of the limiting part 121. The rod part 11 is provided with a mounting through hole 142 for the fixing rivet 14 to pass through. The connecting part 122 is provided with a mounting hole 141 that is interference-fitted with the fixing rivet 14, so that the connecting part 12 and the corresponding rod part 11 form a non-detachable connection, which improves the reliability of the fixing of the connecting part 12 and the rod part 11. Before the curtain rod is transported, the connecting part 122 located on either side of the limiting part 121 and the rod part 11 need to be fixed by the fixing rivet 14 and the fixing bolt 13. Then, at the installation site of the curtain rod, the operator only needs to fix the other end of the rod part 11 to the rod part 11 by the fixing bolt 13, which facilitates the assembly of the curtain rod.

[0041] Reference Figure 2 The end of the connecting part 122 away from the limiting part 121 is provided with a guide slope 124. The guide slope 124 facilitates the insertion of the connecting part 122 into the connecting cavity 111, thereby facilitating the assembly of the curtain rod and improving the assembly efficiency of the curtain rod to a certain extent.

[0042] Reference Figure 1 , Figure 3 and Figure 4 The curtain rod also includes a fixed seat 2 and a rotating seat 3 respectively disposed at both ends of the main rod 1. Both the fixed seat 2 and the rotating seat 3 are fixed to the wall structure by bolts. The cross-section of the main rod 1 in this application can be adapted to two types of curtain fabric lifting methods. In this embodiment, a fixed part 4 that cooperates with the connecting cavity 111 is rotatably connected to the fixed seat 2, a ball wheel 5 is rotatably connected to the rotating seat 3, and a pull bead 51 for controlling the rotation of the ball wheel 5 is slidably connected to the rotating seat 3. A control head 52 that cooperates with the connecting cavity 111 is coaxially disposed on the ball wheel 5. Fixing strips 53 that fit against the inner wall of the connecting cavity 111 are disposed on the outer peripheral walls of the fixed part 4 and the control head 52. There are multiple fixing strips 53, and the fixing strips 53 are arranged in a circular array with the axis of the fixed part 4 or the control head 52 as the center. The fitting part 112 and the avoidance part 113 are engaged between two adjacent fixing strips 53. When the pull bead 51 is pulled, it drives the bead wheel 5 to rotate, which in turn drives the main rod 1 to rotate via the control head 52. Since the fixing part 4 is embedded in the connecting cavity 111, the rotation of the main rod 1 drives the fixing part 4 to rotate relative to the fixing seat 2, improving the stability of raising and lowering the curtain fabric by rotating the main rod 1. This method of rolling up the curtain fabric is simple to operate and has a low cost, offering high cost-effectiveness.

[0043] Example 2:

[0044] The difference from Embodiment 1 is that, referring to Figure 5 , Figure 6 and Figure 7Both the fixed base 2 and the rotating base 3 are rotatably connected to a positioning part 6 that mates with the connecting cavity 111. The positioning part 6 has a clearance groove 61 for engaging the fitting part 112 and the clearance part 113. The rotating base 3 is coaxially provided with an irregularly shaped rotating pin 62, and the corresponding positioning part 6 has a pin through hole 621 that mates with the rotating pin 62. The rotating base 3 is provided with a rotating component for driving the rotating pin 62 to rotate. The positioning part 6 that mates with the fixed base 2 is coaxially provided with a rotating column 63, and the fixed base 2 has a rotating through hole 631 for engaging the rotating column 63. When the main rod 1 rotates, it can drive the rotating column 63 to rotate in the rotating through hole 631, thereby improving the stability of the main rod 1's rotation.

[0045] Reference Figure 7 The rotating components include a meshing worm gear 64 and a worm 641. A housing 65 is provided on the rotating base 3 to accommodate the worm gear 64 and worm 641. Both the worm gear 64 and worm 641 are rotatably mounted within the housing 65. A rotating pin 62 is coaxially fixed to the worm gear 64. A rotating pull ring 642 is provided at the ground-facing end of the worm 641. In practical applications, the rotating pull ring 642 can be driven to rotate using an operating tool, thereby rotating the main rod 1. The operating tool must be equipped with a hook that engages with the rotating pull ring 642. Driving the curtains in this way, compared to the method using a beaded cord 51, is less likely to cause injury to children, is safer, and results in a simpler overall design for the room.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
