[0021] The present application embodiment discloses Figure 1-5A soundproof curtain 1 shown in the figure specifically includes two curtains 1, the tops of the two curtains 1 are each provided with a sliding rod 2, both ends of the sliding rod 2 are threadedly connected with a threaded cap 3, a limiting mechanism is provided on the surface of the sliding rod 2, the limiting mechanism includes a plurality of limiting holes 4 opened on the surface of the sliding rod 2, wherein two of the limiting holes 4 are opened on one side of the threaded cap 3, a plurality of the limiting holes 4 are internally provided with a spring 5, one end of the spring 5 is provided with a limiting column 6, the top of the limiting column 6 is in an arc shape, a plurality of connecting rings 7 are slidably provided on the sliding rod 2, one side of two of the connecting rings 7 are connected to the limiting column 6, one side of the two connecting rings 7 are provided with a card slot, a magnet 8 is provided inside the card slot, and the two connecting rings 7 are magnetically connected by the magnet 8, the threaded caps 3 on both sides of the sliding rod 2 are removed, a plurality of connecting rings 7 are sleeved on the surface of the sliding rod 2, and then the threaded cap 3 is threadedly connected to the sliding rod 2, the two sides of the sliding rod 2 are blocked, and the connecting rings 7 are prevented from entering from both sides of the sliding rod 2 When the curtain 1 slides and falls, and the curtain 1 is pulled to be closed, the connecting ring 7 at the top of the curtain 1 slides on the slide bar 2, wherein the two connecting rings 7 are first magnetically connected by a magnet 8, and then the two curtains 1 are connected by the mother magic layer 10 and the sub-magic layer 11, so that the two curtains 1 will not be easily blown open, and then the connecting ring 7 is limited by the limiting columns 6 on both sides of the connecting ring 7 to prevent the connecting ring 7 from driving the curtain 1 to open due to the action of the airflow, thereby affecting the sound insulation effect of the curtain 1. After separating the two curtains 1, the user needs to use a force greater than the magnet 8 to pull the curtain 1 to separate the two connecting rings 7 at the top that are connected by magnetic attraction. When the connecting ring 7 moves on the slide bar 2, the user needs to use a force greater than the airflow to drive the connecting ring 7 at the top of the curtain 1 to move, so that the connecting ring 7 can squeeze the limiting column 6, and the spring 5 at the bottom of the limiting column 6 drives the limiting column 6 to move downward, so as to slide the connecting ring 7 to one side and open the curtain 1.

[0022] Reference Figure 3 and Figure 4 As shown, the connecting ring 7 is made of plastic material, one side of the connecting ring 7 is movably connected with a fixing column, a plurality of fixing holes 9 are provided on the surface of the curtain 1, the fixing column is connected with the fixing hole 9, one side of the two curtains 1 is respectively provided with a mother magic layer 10 and a sub-magic layer 11, the plastic connecting ring 7 is opened, so that the connecting ring 7 can be connected to the fixing hole 9 on the surface of the curtain 1 through the fixing column, and a plurality of connecting rings 7 are connected to the curtain 1. When the curtain 1 is opened, the mother magic layer 10 and the sub-magic layer 11 between the two curtains 1 are first separated, and the mother magic layer 10 and the sub-magic layer 11 are similar to the existing Velcro technology, and the two curtains 1 are separated.

[0023] Reference Figure 5As shown, the curtain 1 is provided with a front sound insulation layer 12 inside, a reinforcement layer 13 is provided on one side of the front sound insulation layer 12, and a rear sound insulation layer 14 is provided on one side of the reinforcement layer 13. The reinforcement layer 13 inside the curtain 1 is to reinforce the curtain 1 to prevent the curtain 1 from being damaged when being dragged for a long time. The front sound insulation layer 12 and the rear sound insulation layer 14 are both made of flame-retardant polyester cloth, so that the sound insulation effect of the curtain 1 can be improved. The material of the flame-retardant polyester cloth is made of polyester wire, and the polyester material has a certain sound absorption ability. After the sound wave enters the material, due to the presence of many pores and capillaries inside the material, when the sound wave passes through these pores, multiple reflections, scattering and absorption will occur, thereby playing a certain degree of sound insulation role. This structure has a double-layer sound insulation effect, so that the sound insulation effect of the curtain 1 is better.

[0024] The working principle of the utility model is as follows: when installing the curtain 1, the plastic connecting ring 7 is first opened, so that the connecting ring 7 can be connected to the fixing hole 9 on the surface of the curtain 1 through the fixing column, and multiple connecting rings 7 are connected to the curtain 1, and then the threaded caps 3 on both sides of the slide bar 2 are removed, and multiple connecting rings 7 are sleeved on the surface of the slide bar 2, and then the threaded caps 3 are threadedly connected to the slide bar 2 to block the two sides of the slide bar 2 to prevent the connecting rings 7 from sliding and falling from the two sides of the slide bar 2;

[0025] When the curtain 1 is pulled to close, the connecting ring 7 at the top of the curtain 1 slides on the slide bar 2, wherein the two connecting rings 7 are first connected by magnetic attraction through the magnet 8, and then the two curtains 1 are connected through the mother magic layer 10 and the child magic layer 11, so that the two curtains 1 will not be easily blown open, and then the connecting ring 7 is limited by the limiting columns 6 on both sides of the connecting ring 7 to prevent the connecting ring 7 from driving the curtain 1 to open due to the action of airflow, thereby affecting the sound insulation effect of the curtain 1;

[0026] When the curtain 1 needs to be opened, the mother magic layer 10 and the sub-magic layer 11 between the two curtains 1 are first separated. The mother magic layer 10 and the sub-magic layer 11 are similar to the existing Velcro technology. After the two curtains 1 are separated, the user needs to use a force greater than the magnet 8 to pull the curtain 1 to separate the two connecting rings 7 at the top that are connected by magnetic attraction. When the connecting ring 7 moves on the slide bar 2, the user needs to use a force greater than the airflow to drive the connecting ring 7 at the top of the curtain 1 to move, so that the connecting ring 7 can squeeze the limiting column 6, and the limiting column 6 is driven to move downward by the spring 5 at the bottom of the limiting column 6, so as to slide the connecting ring 7 to one side and open the curtain 1.

[0027] The reinforcement layer 13 inside the curtain 1 is used to reinforce the curtain 1 to prevent the curtain 1 from being damaged when being dragged for a long time. The front sound insulation layer 12 and the rear sound insulation layer 14 are both made of flame-retardant polyester cloth, so that the sound insulation effect of the curtain 1 can be improved. The material of the flame-retardant polyester cloth is made of polyester wire. The polyester material has a certain sound absorption ability. After the sound wave enters the material, due to the many pores and capillaries inside the material, when the sound wave passes through these pores, multiple reflections, scattering and absorption will occur, thereby playing a certain degree of sound insulation role. This structure uses double-layer sound insulation to make the sound insulation effect of this type of curtain 1 better.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
