Description

Technical Field

[0001] This utility model relates to the field of folding door curtain technology, specifically to a magnetically foldable door curtain with a Velcro connection structure. Background Technology

[0002] Folding door curtains are a functional door product that combines space division, convenient opening and closing, and environmental adaptability. With their foldable and storage-friendly structural design and diverse material selection, they are widely used in commercial venues, industrial workshops, residential spaces, and public areas, playing an important role in optimizing space utilization efficiency and improving ease of use.

[0003] In practical applications of magnetic folding curtains, the smoothness and stability of the curtain's opening and closing are key factors affecting the user experience. The sliding frame, as the core load-bearing component for the curtain's sliding motion, directly determines its performance. Currently, most traditional magnetic folding curtains on the market use a double-pulley configuration with one pulley on each side of the sliding frame. While this design meets basic sliding requirements, it has significant limitations in actual use: Firstly, the double pulleys only support the weight of the sliding frame and the overall weight of the curtain through two fulcrums, resulting in concentrated and uneven stress. Excessive force on one side can easily cause the frame to tilt, deviate, or even rub against the inner wall of the track, potentially leading to pulley wear or track deformation and shortening the curtain's overall lifespan. Secondly, the small contact area between the double pulleys and the track provides insufficient stability during sliding, especially when the curtain is long or subjected to slight external impacts. The sliding trajectory can easily deviate from the preset path, affecting the smoothness of opening and closing and making it unsuitable for applications requiring high sliding precision and stability. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically foldable door curtain with a Velcro connection structure, in order to solve the problem that the sliding structure at the top of the existing folding door curtain uses a double pulley system, which only supports the weight of the moving frame and the overall weight of the door curtain through two support points. This can easily lead to a concentration and uneven distribution of force points, resulting in unstable sliding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetically foldable door curtain with a Velcro connection structure, including a slide rail, a door curtain 1 and a door curtain 2 at the bottom of the slide rail, both door curtain 1 and door curtain 2 having creases in the middle, magnetic strips fixedly installed on both sides of door curtain 1 and door curtain 2, an iron plate at the top of both door curtain 1 and door curtain 2, a hanging hole in the middle of the iron plate, a hook inside the hanging hole, a pulley slidably installed inside the slide rail, a movable frame inside the slide rail, and shafts rotatably installed at both ends of the movable frame, a Velcro closure 1 at the top of door curtain 1, and a Velcro closure 2 at the top of door curtain 2.

[0006] Furthermore, bolts are fixedly installed at both ends of the iron plate, and bearings are fixedly installed at both ends of the shaft.

[0007] Furthermore, both the first and second curtains have through holes at their tops, and the through holes are aligned with the hanging holes. The iron plates are fixed to the first and second curtains respectively with bolts.

[0008] Furthermore, the top of the hook is threaded, and the top of the hook is fixedly installed to the movable frame by the thread, and the bearing is fixedly installed on one side of the pulley.

[0009] Furthermore, the first type of Velcro fastener is disposed between the iron plate and the first type of curtain, and the second type of Velcro fastener is disposed between the iron plate and the second type of curtain.

[0010] Compared with existing technologies, this utility model provides a magnetically foldable door curtain with a Velcro connection structure. It has the following advantages:

[0011] (1) This utility model sets pulleys on both sides of the movable frame, and the total number of pulleys is four. Compared with the traditional movable frame which is only equipped with two pulleys, this movable frame with four pulleys can evenly distribute the weight of the movable frame itself and the load through multiple support points when sliding inside the slide rail. This effectively reduces the tilting or jamming problem caused by excessive force on one side, and at the same time increases the contact stability between the movable frame and the slide rail, making the door curtain more stable and smooth during the sliding process.

[0012] (2) This utility model sets Velcro at the top of the door curtain. The Velcro is fixed to the top of the door curtain by the cooperation of iron plate and bolt. In actual use, the Velcro at the top of the adjacent door curtains can be quickly fixed by sticking them together. The two sides of the door curtain are attracted by magnetic strips to close the door. If the door curtain needs to be separated, the Velcro can be peeled off to easily separate the door curtains. This connection design with Velcro as the core does not require complicated tools, which greatly simplifies the installation and disassembly of the door curtain. Finally, it achieves the practical effect of convenient connection and flexible disassembly between door curtains, which significantly improves the convenience and flexibility of the door curtain during use.

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] Example 1:

[0024] This utility model provides a magnetically foldable door curtain with a Velcro connection structure, including a slide rail 1, a door curtain 2 and a door curtain 4 at the bottom of the slide rail 1, a crease 3 in the middle of both door curtain 2 and door curtain 4, magnetic strips 5 fixedly installed on both sides of door curtain 2 and door curtain 4, an iron plate 6 at the top of both door curtain 2 and door curtain 4, a hanging hole 8 in the middle of the iron plate 6, a hook 9 inside the hanging hole 8, a pulley 10 slidably installed inside the slide rail 1, a movable frame 11 inside the slide rail 1, and shafts 12 rotatably installed at both ends of the movable frame 11, a Velcro 14 at the top of door curtain 2, and a Velcro 25 at the top of door curtain 4.

[0025] Working principle: The door curtain 1 2 and door curtain 2 4 are connected by magnetic strips 5 on both sides of the door curtain. The iron plate 6 is set on the front and back of the top of the door curtain and is fixed by bolts 7. The bottom of the hook 9 passes through the hanging hole 8 to hang the door curtain. The top of the hook 9 is fixed to the moving frame 11 by threads. The pulleys 10 on both sides of the moving frame 11 are slidably installed inside the slide rail 1. The door curtain is finally installed. The bearings 13 at both ends of the shaft 12 make the rotation between the pulleys 10 and the shaft 12 smoother.

[0026] When one side of the curtain is pushed, either curtain 1 (2) or curtain 2 (4) rolls inside the slide rail 1 with pulley 10. The curtains fold together under the action of crease 3. The periphery of the moving frame 11 is equipped with four pulleys 10, which makes the top of the curtain more stable when moving and prevents the hook 9 from tilting.

[0027] Example 2:

[0028] Based on Embodiment 1, bolts 7 are fixedly installed at both ends of the iron plate 6, and bearings 13 are fixedly installed at both ends of the shaft 12.

[0029] Both the top of the curtain 1 (2) and the curtain 2 (4) have through holes, which are aligned with the hanging holes (8). The iron plate (6) is fixedly installed to the curtain 1 (2) and the curtain 2 (4) respectively by bolts (7). The top of the hook (9) is threaded, and the top of the hook (9) is fixedly installed to the movable frame (11) by threads. The bearing (13) is fixedly installed on one side of the pulley (10). The Velcro 1 (14) is set between the iron plate (6) and the curtain 1 (2), and the Velcro 2 (15) is set between the iron plate (6) and the curtain 2 (4).

[0030] Working principle: Hook and loop fastener 14 is placed between curtain 2 and iron plate 6. One end of bolt 7 passes through iron plate 6, hook and loop fastener 14 and curtain 2 in sequence, and finally passes through iron plate 6 on the back of curtain 2. It is then fixed with nut and bolt 7. Hook and loop fastener 14 is installed. The installation method of hook and loop fastener 2 is similar to that of hook and loop fastener 14. The top of curtain 2 and curtain 2 can be connected by the adhesion of hook and loop fastener 14 and hook and loop fastener 2 15. In this way, even if the magnetic strips 5 are separated, curtain 2 and curtain 2 will not be completely separated. After the curtains are separated, the magnetic strips 5 can be quickly attracted together because the top of the curtains are connected, and curtain 2 and curtain 2 are re-adheded.

[0031] Simply separate the Velcro 14 and Velcro 25 to detach the curtain; the operation is very convenient.

[0032] Since the top of the hook 9 is fixedly installed to the movable frame 11 by a thread, the hook 9 can be rotated and raised and lowered inside the movable frame 11, thus changing the hanging height of the curtain for easy adjustment.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
