[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figure 1-8This embodiment provides the following technical solution: a dustproof double-leaf door curtain for a large steel structure workshop, including a door frame 1 and a door curtain body 2. A guide rail 3 is provided on the front side of the top of the door frame 1. The guide rail 3 is fixedly connected to the door frame 1 by a pad. A sliding cavity 12 is provided in the guide rail 3. A movable groove 13 penetrating the guide rail 3 is provided at the bottom of the sliding cavity 12.

[0028] like Figure 2 As shown, a rope 4 is rotatably connected to the guide rail 3. The rope 4 is set along the length of the guide rail 3 and is located between the guide rail 3 and the gantry 1. A tensioner 7 is set at one end of the top of the gantry 1. A drive wheel 8 is rotatably connected to the tensioner 7 and driven by a drive device 9. A guide wheel 10 is rotatably connected to the other end of the top of the gantry 1. The guide wheel 10 and the drive wheel 8 are connected by the rope 4. Through the drive device 9, the drive wheel 8 and the guide wheel 10, the rope 4 can move cyclically along a loop path.

[0029] In some embodiments, the tensioner 7 is connected to the gantry 1 by bolts. By rotating the bolts, the tensioner 7 drives the drive wheel 8 and the drive device 9 to move closer to or away from the guide wheel 10, thereby adjusting the tension of the tensioner 7.

[0030] like Figure 8 As shown, in some embodiments, a limiting frame 11 is rotatably connected to the guide wheel 10. The limiting frame 11 is fixedly connected to the gantry 1. An anti-detachment cavity for the rope 4 is formed between the limiting frame 11 and the guide wheel 10. Through the limiting frame 11, the guide wheel 10 can be driven to rotate during the cyclical movement of the rope 4. Furthermore, during the rotation of the guide wheel 10 by the rope 4, the rope 4 can be prevented from detaching from the guide wheel 10, thereby preventing the equipment from operating normally.

[0031] like Figure 1 , Figure 2 As shown, a first curtain hanger 5 is fixedly connected to the upper edge of the rope 4, and a second curtain hanger 6, which intersects with the first curtain hanger 5, is fixedly connected to the lower edge of the rope 4. A curtain body 2 is fixedly connected to both the first curtain hanger 5 and the second curtain hanger 6. The first curtain hanger 5 and the second curtain hanger 6 move closer to each other or further away from each other as the rope 4 moves back and forth, thus opening or closing the double curtain. During the cyclical movement of the rope lock along the circular path, the first curtain hanger 5 and the second curtain hanger 6 pull the curtain body 2 to change as the rope 4 moves. When the first curtain hanger 5 and the second curtain hanger 6 move closer to each other or further away from each other, the double curtain can be opened or closed. This design features a simple structure, low maintenance cost, and high safety performance.

[0032] like Figure 2As shown, several auxiliary pulleys 14 are slidably connected to the sliding cavity 12, located on the right side of the first curtain hanger 5 and on the left side of the sliding cavity 12, respectively. An auxiliary curtain plate 15 extending to the outside of the movable groove 13 is rotatably connected to the auxiliary pulleys 14. The auxiliary curtain plate 15 is fixedly connected to the curtain body 2. Through the auxiliary pulleys 14 and the auxiliary curtain plate 15, the curtain body 2 fixed on the first curtain hanger 5 and the curtain body 2 fixed on the second curtain hanger 6 can be limited, thereby enabling the curtain body 2 to be unfolded or retracted.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the first curtain hanger 5 includes a first movable plate 51, a first active pulley 52, an outer plate 53, a first main curtain panel 54, and a first locking plate 55. The first movable plate 51 is slidably connected inside the movable groove 13. The first active pulley 52 is slidably connected to the first movable cavity on the first movable plate 51. The outer plate 53 is located on one side of the guide rail 3 and is fixedly connected to the first movable plate 51. The bottom of the outer plate 53 is fixedly connected to the first curtain panel, and the top of the outer plate 53 is fixedly connected to the first locking plate 55. The first locking plate 55 is fixedly connected to the rope 4 by a buckle. With the first movable plate 51, the first active pulley 52, the outer plate 53, the first main curtain panel 54, and the first locking plate 55, the first curtain hanger 5 can be stably slidably connected to the guide rail 3, and the first curtain hanger 5 can also be fixed to the upper edge of the rope 4. Thus, as the rope 4 moves along the loop path, it drives the first curtain hanger 5 and the curtain body 2 on the right side to move.

[0034] like Figure 2 , Figure 6 and Figure 7 As shown, the second curtain hanger 6 includes a second movable plate 61, a second main curtain panel 62, a second active pulley 63, and a second locking plate 64. The second movable plate 61 is slidably connected inside the movable groove 13. The second main curtain panel 62 is fixedly connected to the bottom of the second movable plate 61. The second active pulley 63, which slides in the sliding cavity 12, is provided on the top of the second movable plate 61. The second locking plate 64 is fixedly connected to one side of the second movable plate 61. The second locking plate 64 is fixedly connected to the rope 4 by a buckle. With the second movable plate 61, the second main curtain panel 62, the second active pulley 63, and the second locking plate 64, the second curtain hanger 6 can be stably slidably connected to the guide rail 3, and at the same time, the second curtain hanger 6 can be fixed to the lower edge of the rope 4. Thus, as the rope 4 moves along the loop path, it drives the second curtain hanger 6 and the curtain body 2 on the left side to move.

[0035] The working principle of this utility model is as follows: When the double-leaf curtain needs to be opened, the drive device 9 is started by remote control, which makes the drive wheel 8 rotate. Under the action of the rope 4, the guide wheel 10 also rotates. The rope 4 moves along the loop path on the door frame 1. While the rope 4 is moving, the first curtain hanger 5 drives the right curtain body 2 to slide to the right. The curtain body 2 also drives several auxiliary pulleys 14 on the right to slide to the right, so that the right curtain body 2 gradually retracts. At the same time, the second curtain hanger 6 drives the left curtain body 2 to slide to the left. The curtain body 2 also drives several auxiliary pulleys 14 on the left to slide to the left, so that the left curtain body 2 gradually retracts. In this way, with the cooperation of the first curtain hanger 5 and the second curtain hanger 6, the double-leaf curtain is in the open state.

[0036] Conversely, when the remote control is activated, the drive device 9 moves the rope 4 in the opposite direction. At this time, the first curtain hanger 5 and the second curtain hanger 6 move simultaneously along the guide rail 3 towards the center of the guide rail 3, thereby causing the right curtain body 2 and the left curtain body 2 to move towards the center at the same time. Since the first curtain hanger 5 and the second curtain hanger 6 are staggered, an overlapping area will be formed on the side of the left curtain body 2 and the right curtain body 2 facing each other, thus realizing that the double curtain is in the closed state.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be...

[0038] It is included within the protection scope of this utility model.
