Description

Technical Field

[0001] This utility model belongs to the field of door curtain rod technology, and specifically relates to a door curtain rod. Background Technology

[0002] As an important supporting component of door curtains, the performance of the curtain rod directly affects the curtain's usability and user experience.

[0003] Currently, traditional curtain rods have many shortcomings. On the one hand, regarding the closing effect of the curtain, existing curtain rods fail to consider the full sealing requirements of the curtain in their design. Many curtain rods cannot ensure that the curtain can be tightly sealed when closed, causing outside light and dust to easily enter the room through the gaps between the curtain and the door frame and the wall during use, affecting the curtain's intended functions of blocking light, protecting privacy, and preventing dust.

[0004] On the other hand, when a user wants to fully close the curtain and pulls it to the end of the curtain rod, their hand can easily accidentally hit the door frame, wall, or other objects, causing hand injury. Furthermore, existing methods of securing the curtain rod are often not secure or reliable enough. Over time, due to frequent pulling, daily vibrations, or environmental factors, the curtain rod can easily loosen or fall off. This not only affects the normal use of the curtain but may also pose a potential safety threat to surrounding people and property, such as a falling curtain rod injuring someone or damaging property.

[0005] In summary, existing curtain rods have significant shortcomings in terms of curtain sealing, security, and secure fixing. There is an urgent need for a new type of curtain rod to solve these problems and improve the overall performance and user experience of curtain rods. Utility Model Content

[0006] The purpose of this utility model is to provide a door curtain rod that solves the technical problems of existing door curtain rods, such as door curtains not closing tightly, the risk of hand injury from collision when pulling the door curtain to the end, and the door curtain rods being prone to loosening and falling off due to vibration or frequent pulling.

[0007] To achieve the above objectives, this utility model provides a door curtain rod, characterized in that: it includes a main rod, which is a tubular structure with connecting rods at both ends. A limiting component and a magnet are provided on the main rod. The limiting component is used to limit the position of the magnet inside the main rod and includes a limiting hole, a baffle, and a limiting block.

[0008] One end of the connecting rod is inserted into the main rod and movably connected to the main rod. The outer surface of the connecting rod is in contact with the inner surface of the main rod. The other end is provided with a threaded structure and connected to a bending rod. The overall length of the curtain rod can be adjusted by adjusting the connection depth between the connecting rod and the bending rod.

[0009] The bending rod is U-shaped, with one end connected to the connecting rod having a thread that matches the thread of the connecting rod, and the thread length being longer than the thread length on the connecting rod; the other end has an end cap, and a fixing mechanism is provided at the end connected to the main rod.

[0010] A fixing mechanism is provided for contacting and securing the curtain rod with the mounting surface, and also has a length adjustment function.

[0011] A connecting ring is fitted onto the main rod.

[0012] Preferably, the main rod has limiting holes at both ends, two baffles between the two limiting holes, two magnets between the baffles and the limiting holes, and limiting blocks installed in the limiting holes; the magnets are limited between the baffles and the limiting blocks.

[0013] Preferably, the magnet is a neodymium iron boron magnet, and the two magnets are arranged adjacent to each other with the same pole.

[0014] Preferably, the two ends of the main rod are chamfered, the diameter of the main rod is larger than the diameter of the connecting rod, and the end of the connecting rod inserted into the main rod has a notch that matches the limiting block.

[0015] Preferably, the end of the bending rod connected to the connecting rod is chamfered; the bending rod is rotated downward at a certain angle relative to the main rod, so that the central axis of the bending rod is lower than the central axis of the main rod, so that the curtain can be well maintained at the end of the bending rod after being pulled to the end, ensuring that the curtain is always in a sealed state.

[0016] Preferably, the fixing mechanism includes a connecting plate, a fixing plate, a mating plate, a rubber pad, and a screw; the connecting plate is fixed to one end of the bending rod and the connecting rod, and to the side opposite to the bending direction; one side of the fixing plate is fixedly connected to the connecting plate, and the other side is provided with a mating plate, and the other side of the mating plate is fixedly provided with a rubber pad, which is in contact with the door frame or wall.

[0017] Preferably, the fixing plate is provided with a through threaded hole; the mating plate is provided with a non-through circular hole at a position corresponding to the threaded hole on the fixing plate; the screw is connected to the fixing plate by threads and extends into the circular hole of the mating plate and contacts the bottom of the circular hole.

[0018] Preferably, the side of the rubber pad that contacts the door frame protrudes beyond the apex of the bend of the curved rod, creating a space between the curved rod and the wall for the curtain connector to move.

[0019] Preferably, a transparent observation hole is provided at an adjacent position of the two magnets on the main rod to observe the change in the gap between the two magnets so as to adjust the fixing mechanism in a timely manner.

[0020] Preferably, the connecting ring has an opening, which serves to connect the curtain to the curtain rod and to allow the connecting ring to pass through the fixing mechanism.

[0021] The above-mentioned technical solutions of one or more of the door curtain rods provided in this embodiment of the utility model have at least one of the following technical effects:

[0022] This utility model discloses a door curtain rod. By incorporating a curved rod, when a user wishes to close the door curtain tightly, they pull the curtain left and right. When the curtain is pulled close to the end of the rod, the user changes the direction of pulling the curtain forward. The curtain then moves in the opposite direction along the curved rod after approaching the door frame. This allows the curtain to better close to the door frame or wall when closed, thereby optimizing the tightness of the curtain closure, reducing gaps, and enhancing the effects of light blocking, dust prevention, and privacy protection. It also prevents hands from directly hitting the door frame or wall, reducing the risk of accidental collisions.

[0023] This utility model discloses a door curtain rod. With the cooperation of a main rod, connecting rod, and fixing mechanism, the length of the door curtain rod can be flexibly adjusted and firmly fixed. By adjusting the overlap length of the connecting rod and the main rod, it can meet the needs of door openings of different widths. The fixing mechanism, under the action of the fixing plate and the mating plate, makes fine adjustments by adjusting the depth of the screw into the fixing plate, ensuring a tighter fit between the door curtain rod and the installation surface. This effectively prevents loosening or detachment due to frequent pulling or vibration, improving the firmness of the door curtain rod. Simultaneously, the magnets inside the door curtain rod interact to generate a repulsive force, which in turn generates a repulsive force between the main rod and the connecting rod, preventing the door curtain rod from loosening or detaching after prolonged use due to frequent pulling, daily vibration, or environmental factors.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] In one embodiment of this utility model, such as Figure 1-4 As shown, a curtain rod is provided, including a main rod 10, a connecting rod 20, a bending rod 30, a fixing mechanism 40, and a connecting ring 50.

[0039] The main rod 10 is a tubular structure with connecting rods 20 at both ends. The diameter of the main rod 10 is larger than the diameter of the connecting rod 20, so that the connecting rod 20 can be inserted into the main rod 10. The two ends of the main rod 10 are chamfered, so that the curtain can slide more smoothly along the main rod 10 and the connecting rod 20.

[0040] One end of the connecting rod 20 is directly inserted into the main rod 10 and is movably connected to the main rod 10. The other end has a threaded structure and is connected to a bent rod 30.

[0041] The end of the bending rod 30 connected to the connecting rod 20 is provided with a thread that matches the thread on the connecting rod 20, and the length of the thread structure in the bending rod 30 is longer than the length of the thread on the connecting rod 20, so that the connecting rod 20 can be flexibly set at different depths in the bending rod 30, thereby achieving the purpose of controlling the distance between the main rod 10 and the bending rod 30.

[0042] To ensure that the curtain can slide more smoothly along the connecting rod 20 and the bending rod 30, the outer surface of the connecting rod 20 is in contact with the inner surface of the main rod 10, and the end of the bending rod 30 connected to the connecting rod 20 is also chamfered.

[0043] The bending rod 30 is U-shaped. By adjusting the length of the connecting rod 20 within the bending rod 30, the bottom of the bending rod 30 can be brought close to the door frame, with the distance between it and the door frame sufficient for the curtain to move. Preferably, the bending rod 30 can be rotated downwards at a certain angle relative to the main rod 10, so that the central axis of the bending rod 30 is lower than the central axis of the main rod 10. This allows the curtain to be well maintained at the end of the bending rod 30 after being pulled to the end, ensuring that the curtain is always sealed.

[0044] A fixing mechanism 40 is fixed at one end of the bending rod 30 connected to the connecting rod 20 and on the side opposite to the bending direction of the bending rod 30. The overall length of the curtain rod is adjusted by the connecting rod 20 so that the length of the curtain rod matches the width of the door. The fixing mechanism 40 contacts the door frame or wall and thus engages with the door frame. By adjusting the length of the fixing mechanism 40, the curtain rod can be more firmly fixed in the door frame.

[0045] A connecting ring 50 is fitted onto the main rod 10. The connecting ring 50 has an opening and a door curtain is fixedly connected to it. The connecting ring connects the door curtain to the door curtain rod. The opening on the connecting ring 50 allows the connecting ring 50 to pass through the fixing mechanism 40.

[0046] The main rod 10 has limiting holes 11 at both ends, and a position for inserting a connecting rod 20 is reserved between the limiting holes 11 and the end of the main rod 10. Two baffles 12 are provided between the two limiting holes 11 in the main rod 10. Two magnets 13 are provided between the baffles 12 and the limiting holes 11. A limiting block 14 is installed in the limiting hole 13. The limiting block 14 cooperates with the baffles 12 to restrict the two magnets 13 to a fixed position in the main rod 10. The limiting holes 11, baffles 12 and limiting blocks 14 constitute a limiting component.

[0047] The magnet 13 is a neodymium iron boron (NdFeB) magnet, which is an alloy composed of elements such as neodymium, iron, and boron. It possesses excellent magnetic properties, is small in size, and has strong magnetic force. Its crystal structure exhibits high symmetry and stability, enabling the formation of very strong magnetic domains. This structure gives NdFeB magnets high coercivity, meaning they have a strong ability to resist changes in magnetic fields and will not demagnetize even under prolonged contact with the same poles.

[0048] Two magnets 13 are arranged adjacent to each other with the same poles. According to the principle that like poles of a magnetic field repel each other, the two magnets 13 generate a repulsive force. The other ends of the two magnets 13 are in contact with the baffle 13 and the limiting block 14, respectively, and the two magnets 13 apply pressure to the baffle 13 and the limiting block 14. When the connecting rod 20 is inserted into the main rod 10, the magnet 13 in contact with the limiting block 14 also comes into contact with the connecting rod 20. At this time, after the limiting block 14 is removed, the pressure originally applied to the limiting block 14 by the magnet 13 is applied to the connecting rod 20. The connecting rod 20 and the bending rod 30 are fixedly connected by threads. Under the action of the fixing mechanism 40, the bending rod 30 is locked between the door frame or the wall. Under the long-term use of the curtain rod, frequent pulling, daily vibration or environmental factors, when the connection between the curtain rod and the door frame becomes loose, a gap is generated between the two magnets 13, but there is still a strong repulsive force to ensure that the curtain rod will not fall off.

[0049] As a preferred option, a transparent observation hole can be provided at the position where the two magnets 13 are adjacent on the main rod 10. When a large gap occurs between the two magnets 13, the length of the fixing mechanism 40 can be adjusted in time to strengthen the firmness of the curtain rod between the door frame or the wall.

[0050] The end of the connecting rod 20 that is inserted into the main rod 10 has a notch 21 that matches the limiting block 14, so that when the limiting block 14 is installed in the limiting hole 11, the connecting rod 20 can also be inserted into the main rod 10 and come into contact with the magnet 13.

[0051] The end of the bending rod 30 is provided with a head 31, which serves to prevent the curtain from being pulled too much and falling off the curtain rod.

[0052] The fixing mechanism 40 consists of a connecting plate 41, a fixing plate 42, a mating plate 43, a rubber pad 44, and a screw 45.

[0053] The connecting plate 41 is fixedly disposed at the end where the bending rod 30 is connected to the connecting rod 20 and on the side opposite to the bending direction of the bending rod 30. The connecting plate 41 serves to connect the fixing plate 42 to the bending rod 30 while allowing the connecting ring 50 to pass through.

[0054] The fixing plate 42 is provided with multiple through threaded holes. One side of the fixing plate 42 is fixedly connected to the connecting plate 41, and the other side is provided with a mating plate 43. The mating plate 43 is provided with a non-through round hole at the position corresponding to the threaded hole on the fixing plate 42. A rubber pad 44 is fixedly provided on the other side of the mating plate 43. The rubber pad 44 contacts the door frame or wall. The side of the rubber pad 44 that contacts the door frame protrudes from the apex of the curved part of the bent rod 30, so that a space is formed between the bent rod 30 and the wall for the connecting ring 50 to move.

[0055] The screw 45 is connected to the fixing plate 42 via a threaded connection, and extends through the fixing plate 42 into the round hole of the mating plate 43, contacting the bottom of the round hole. As the screw 45 continues to extend towards the mating plate 43, the mating plate 43 gradually moves away from the fixing plate 42, thereby lengthening the fixing mechanism 40 and increasing the firmness of the curtain rod fixed to the door frame or wall.

[0056] The working principle of this utility model is as follows: Before installation, a limit block 14 is installed in the limit hole 11 of the main rod 10. Two magnets 13 are provided between the limit block 14 and the baffle 12. The magnets 13 are arranged with the same pole in contact and are restricted in the main rod 10 by the baffle 12 and the limit block 14. The connecting ring 50 is put on the main rod 10. Then, the unthreaded end of the connecting rod 20 is inserted into the main rod 10 and contacts the magnet 13. Next, the bending rod 30 is connected to the threaded end of the connecting rod 20. In the next step, the fixing plate 42 and the mating plate 43 are connected by a screw 45, so that the screw 45 passes through the fixing plate 42 and contacts the bottom of the round hole in the mating plate 43, and at the same time, the fixing plate 42 and the mating plate 43 are in contact. By rotating the connecting rod 20, the depth of the connecting rod 20 inserted into the bending rod 30 is adjusted, thereby matching the total length of the main rod 10, connecting rod 20, bending rod 30, and fixing mechanism 40 with the spacing between the door frames, thus securing the curtain rod between the door frames. Further tightening of the screw 45 allows it to continue extending into the round hole of the mating plate 43, separating the fixing plate 42 from the mating plate 43. Under the pressure of the screw 45, the mating plate 43 ensures that the rubber pad 44 is in tight contact with the door frame or wall, achieving a stable fixation of the curtain rod. Finally, the limiting block 14 is removed and connected to the connecting rod 20. The magnet 13 in contact with the connecting rod 20 applies pressure, and the magnet 13 in contact with the baffle 12 applies pressure to the main rod 10. When the curtain rod becomes loose due to frequent pulling, daily vibration, or environmental factors after long-term use, a gap will be generated between the two magnets 13, but there will still be a strong repulsive force to ensure that the curtain rod will not fall off. The user can use the transparent observation hole set at the position of the two magnets 13 on the main rod 10 to find that the gap between the two magnets 13 is large, and adjust the length of the fixing mechanism 40 in time to strengthen the firmness of the curtain rod between the door frame or wall.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
