Description

Technical Field

[0001] This application relates to the field of lifting curtain frames, and more specifically, to a beaded lifting curtain frame. Background Technology

[0002] A beaded curtain rail is a curtain track system that uses a beaded chain or beaded wheel mechanism to control the raising and lowering of curtains.

[0003] Patent document CN216797282U discloses a height-adjustable curtain rod, including a frame base, a top rod, and a lifting rod. The frame base has a drive mechanism in the middle for rotating the top rod. A winch is sleeved at each end of the top rod. The lifting rod is connected to the top rod at both ends via ropes wound around the winches. The drive mechanism includes a drive seat on the frame base, a drive motor on the drive seat, a connecting foot on the drive seat that is sleeved with the top rod via a bearing, and a gear fixed to the top rod that meshes with the drive motor. This structure enables electric lifting, greatly reducing the labor intensity of changing curtains and making it more convenient. The drive motor rotates the top rod, which in turn rotates the winches, thus raising and lowering the lifting rod. The lifting rod can be equipped with a hook track and hooks for hanging bed curtains.

[0004] The aforementioned application document uses a motor to raise and lower the lifting rod, which is costly; at the same time, since the lifting rod is in a raiseable state, there is a risk of it falling after the curtains are hung.

[0005] Therefore, a beaded lifting curtain rack is provided. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a beaded curtain rod lifter, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A beaded curtain rod lifter includes a mounting frame. A transmission assembly is installed inside the mounting frame. A mounting bracket is mounted at the bottom of the transmission assembly. An anti-fall assembly is installed inside the mounting frame and at the top of the mounting bracket. The anti-fall assembly includes a fixed cylinder. A circular block is fixedly connected to the upper end of the fixed cylinder. A receiving groove is formed inside the circular block. A through hole is formed in the inner wall of the receiving groove, and a movable rod is slidably connected inside the through hole. A triangular block is fixedly connected to the inner end of the movable rod. An mounting block is fixedly connected to the inner wall of the mounting frame. An mounting shaft is fixedly connected to the bottom of the mounting block. Conical blocks A and B are fixedly connected to the bottom and outer wall of the mounting shaft.

[0007] Preferably, the fall arrestor assembly further includes spring A and spring B, with both ends of spring A fixedly connected to the receiving groove and the triangular block, respectively.

[0008] Preferably, the transmission assembly includes a transmission box, which is disposed inside the mounting frame. The transmission box contains plastic beads. A rotating rod is rotatably connected to the inner wall of the mounting frame, and the other end of the rotating rod is fixedly connected to the inner head of the transmission box. A drum is fixedly sleeved on the outer wall of the rotating rod. A tape is wound around the outer wall of the drum, and one end of the tape is fixedly connected to the outer wall of the drum. The bottom of the tape is fixedly connected to the mounting frame.

[0009] Preferably, the bottom of the mounting bracket is provided with a sliding groove, and a hook is slidably connected inside the sliding groove, and a lubrication component is provided inside the mounting frame.

[0010] Preferably, the lubrication assembly includes an oil reservoir, which is fixedly connected to the inner side of the mounting frame.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] See Figures 1-5 This embodiment provides a beaded lifting curtain frame, including a mounting frame 1. A transmission component 2 is provided inside the mounting frame 1. A mounting bracket 3 is mounted at the bottom of the transmission component 2. An anti-fall component 4 is provided inside the mounting frame 1 and at the top of the mounting bracket 3. The anti-fall component 4 includes a fixed cylinder 41. A circular block 42 is fixedly connected to the upper end of the fixed cylinder 41. A receiving groove 43 is opened inside the circular block 42. A through hole is opened in the inner wall of the receiving groove 43, and a movable rod 44 is slidably connected inside the through hole. A triangular block 45 is fixedly connected to the inner end of the movable rod 44. An mounting block 47 is fixedly connected to the inner wall of the mounting frame 1. An mounting shaft 48 is fixedly connected to the bottom of the mounting block 47. A conical block A49 and a conical block B410 are fixedly connected to the bottom and outer wall of the mounting shaft 48.

[0028] The fall arrestor assembly 4 also includes spring A46 and spring B411, with the two ends of spring A46 being fixedly connected to the receiving groove 43 and the triangular block 45, respectively.

[0029] The transmission assembly 2 includes a transmission box 21, which is located inside the mounting frame 1. A plastic pull bead 22 is installed inside the transmission box 21. A rotating rod 23 is rotatably connected to the inner wall of the mounting frame 1, and the other end of the rotating rod 23 is fixedly connected to the inner head of the transmission box 21. A drum 24 is fixedly sleeved on the outer wall of the rotating rod 23. A winding strip 25 is wound around the outer wall of the drum 24, and one end of the winding strip 25 is fixedly connected to the outer wall of the drum 24. The bottom of the winding strip 25 is fixedly connected to the mounting frame 3.

[0030] The bottom of the mounting bracket 3 is provided with a sliding groove, and a hook 6 is slidably connected inside the sliding groove. A lubrication component 5 is provided inside the mounting frame 1.

[0031] In practical use, when it is necessary to hang the curtains, the plastic pull bead 22 is pulled to make the transmission components inside the transmission box 21 rotate, which in turn drives the rotating rod 23 to rotate through the control head. The roller 24 fixed on the outside will then rotate, and the roller 25 wound on the outside will gradually unwind. The mounting bracket 3 located at the bottom of the roller 25 will then descend. When it descends to a suitable height, the curtains can be hung on the top of the hook 6, thus avoiding climbing and making it suitable for the elderly and pregnant women. After hanging, the mounting bracket 3 is pulled up. When the mounting bracket 3 rises to the bottom of the mounting frame 1, the conical block A49 will enter the receiving groove 43 inside the circular block 42, and then the conical block A49 will contact the triangular block 45. At this time, the mounting bracket 3 continues to rise. Since the outside of the conical block A49 is inclined, the triangular block 45 will move outward in the same direction as the movable rod 44 during the rise. When the triangular block 45 moves to the top of the conical block A49... Under the action of spring A46, triangular block 45 will return to its original position, and the bottom of triangular block 45 will rest on the top of cone block A49, thus achieving the effect of preventing fall. When the mounting bracket 3 needs to be moved downward, the mounting bracket 3 is pulled up first, and triangular block 45 will continue to rise and contact cone block B410. Since the contact surface is inclined, triangular block 45 will also move to the side. When it moves to the side of cone block B410, the mounting bracket 3 is pulled down, and triangular block 45 will descend. Since the bottom of triangular block 45 is flat, it will drive cone block B410 down until it is in contact with cone block A49. At this time, since cone block B410 cannot descend, triangular block 45 will descend with it, and then slide from the side of cone block B410 to the side of cone block A49, and then move to the bottom of cone block A49, thereby pulling down the mounting bracket 3.

[0032] Example 2

[0033] See Figures 1-5 Based on Embodiment 1, the lubrication assembly 5 includes an oil reservoir 55, which is fixedly connected to the inner side of the mounting frame 1. A hydraulic chamber 51 is fixedly connected to the inner side of the mounting frame 1. Hydraulic rods A52 and B53 are slidably connected inside the two side ports of the hydraulic chamber 51. A movable block 54 is fixedly connected to the other end of the hydraulic rod B53. A connecting pipe 56 is installed at the bottom oil outlet of the oil reservoir 55. An inlet is opened on the outer wall of the transmission box 21, and a transport pipe 57 is installed inside the inlet. The connecting pipe 56 is connected to the transport pipe 57. The end of the hydraulic rod A52 away from the hydraulic chamber 51 is slidably connected to the inside of the transport pipe 57. A stop block 58 is fixedly connected to the outer end of the movable rod 44.

[0034] One-way valves are installed at the connection between transport pipe 57 and transmission box 21, and at the connection between connecting pipe 56 and transport pipe 57.

[0035] In practical use, when the movable rod 44 moves outward, the abutment 58 on its side moves outward, which in turn squeezes the movable block 54. The movable block 54 then drives the hydraulic rod B53 to slide into the hydraulic chamber 51. The hydraulic rod A52 at the other end of the hydraulic chamber 51 then slides into the transport pipe 57, thus acting as a piston. This squeezes the lubricating oil inside the transport pipe 57 onto the gears inside the transmission box 21, ensuring the smooth operation of the transmission box 21. When resetting, the oil tank 55 replenishes the lubricating fluid into the transport pipe 57 through the bottom connecting pipe 56. The one-way valve inside the connecting pipe 56 prevents the lubricating fluid inside the transport pipe 57 from flowing back into the oil tank 55 when the hydraulic rod A52 is pushed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
