[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] It should also be noted that the azimuth terms such as left, right, up and down in the embodiments of the present application are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0026] Please refer to Figure 2-7 , the projection curtain 100 disclosed in the present application includes a curtain main body 10, a curtain hanging strap 11, and a curtain hanging buckle 12; the curtain hanging strap 11 is disposed on the non-display side of the curtain main body 10, and the curtain hanging buckle 12 includes a first side wall 121, a second side wall 122, and a bottom wall 123, and the first side wall 121, the second side wall 122, and the bottom wall 123 enclose to form a cavity; the curtain hanging strap 11 is hung into the cavity of the curtain hanging buckle 12 from the entrance of the cavity, the first side wall 121 of the curtain hanging buckle 12 abuts against the curtain main body 10, and the second side wall 122 of the curtain hanging buckle 12 is fixedly connected to the wall body 01 on which the projection curtain is hung. It should be noted that the non-display side of the curtain main body 10 refers to the back of the curtain, the side away from the audience, and the side close to the cavity.

[0027] The projection curtain in the present application adopts the combination of the curtain hanging strap 11 disposed on the back of the curtain main body and the curtain hanging buckle 12 fixed on the wall body 01 to hang the projection curtain, avoiding the technical problem that the edge of the curtain is prone to wrinkle caused by the hanging hole scheme in the prior art, and the projection curtain provided in the present application does not have any other components except the black edge 101 on the display side, improving the user's viewing experience and bringing a better product experience to the user.

[0028] In addition, it should be noted that multiple curtain hanging straps 11 can be provided on one side of the projection curtain 100 in the present application, or only one can be provided on each side of the projection curtain 100. In a specific embodiment, such as Figure 5As shown, there are 5 curtain straps 11 provided on each long side of the projection screen 100, and 3 curtain straps 11 are provided on each short side. Additionally, Figure 5 In the embodiment shown in, each curtain strap 11 corresponds to a curtain buckle 12. At this time, the length of the curtain buckle 12 is equivalent to that of the curtain strap 11 ( Figure 5 What is actually shown in is the state where the curtain strap is hung into the curtain buckle 12). Of course, in other embodiments, multiple curtain straps 11 can also correspond to one curtain buckle 12. For example, 2 curtain straps 11 as shown in Figure 5 correspond to 1 longer curtain buckle 12, or 3 curtain straps 11 as shown in the figure correspond to 1 longer curtain buckle, etc. For example, in one embodiment, there are 6 curtain straps 11 provided on the long side of the screen 100, and 4 curtain straps 11 are provided on the short side. Every 2 curtain straps are correspondingly configured with 1 curtain buckle 12. Then, 3 curtain buckles 12 are correspondingly configured on the long side of the screen, and 2 curtain buckles 12 are correspondingly configured on the short side. A total of 10 curtain buckles 12 are required for the entire screen 100. The solution of multiple curtain straps 11 corresponding to 1 curtain buckle 12 can reduce the steps for users to install the screen and further improve the user experience.

[0029] In another embodiment, one curtain strap 11 is provided on each side of the projection screen 100. Considering that the curtain buckle 12 is usually made of a rigid and non-foldable material, if only one curtain buckle 12 is provided in cooperation with the curtain strap 11, it is not easy to transport. At this time, 2 or more curtain buckles 12 can be correspondingly configured according to the size of the screen 100, which can not only meet the requirement of the flatness of the screen suspension but also facilitate transportation and user installation. It should be noted that when one curtain strap 11 is provided in this embodiment to take into account the flatness of the screen, multiple nodes can be selected in the middle of the curtain strap 11 to be stitched to the curtain body 10, thereby avoiding problems such as wrinkles and collapses in the middle of the projection screen 100 due to its too large size.

[0030] Additionally, as Figure 7 shown, the curtain strap 11 can be stitched at both ends along the side of the screen, that is, the left and right ends are stitched on the long side, and the upper and lower ends are stitched on the short side. It can also be stitched at both ends perpendicular to the side of the screen, that is, the upper and lower ends are stitched on the long side, and the left and right ends are stitched on the short side. The cavity entrance of the curtain buckle 12 just needs to match the curtain strap 11.

[0031] Additionally, preferably, in order to further improve the user experience of the product and prevent the user from seeing the stitching line of the curtain strap 11 on the black edge on the front of the screen, the stitching line can be hidden on the back of the screen by means of internal stitching.

[0032] Preferably, in order to ensure a better fit between the projection screen 100 and the wall 01, the thickness of the curtain hook 12 can be reduced, that is, the distance from the first side wall 121 to the second side wall 122 can be decreased. At this time, in one embodiment, in order to ensure the stiffness of the curtain hook 12, a reinforcing rib 124 can be added. Specifically, the reinforcing rib 124 extends from the first side wall 121 to the front of the second side wall 122 or from the second side wall 122 to the front of the first side wall 121, leaving a space for the curtain hanging strap 11 to be inserted. In addition, the reinforcing rib 124 can be connected to the bottom wall 123 or not connected to the bottom wall 123. In other embodiments, the reinforcing rib 124 can also be not provided, and a material with better stiffness can be used when reducing the thickness of the curtain hook 12.

[0033] It should be noted that the curtain hook 12 can be connected to the wall 01 through a colloid, such as applying nail-free glue on the back of the curtain hook 12 or pasting a double-sided adhesive back glue on the back of the curtain hook 12, or it can also be connected to the wall 01 through a screw. A screw hole 1221 for the screw to pass through is provided on the second side wall 122 of the curtain hook 12.

[0034] In one embodiment, the cross-section of the curtain hook 12 is U-shaped, and the bottom wall 123 is an arc-shaped wall.

[0035] In one embodiment, the first side wall 121 of the curtain hook 12 is composed of a plurality of discontinuous walls, which can further reduce the weight of the curtain hook 12.

[0036] In addition, it should be noted that the ratio of the total length of the curtain hanging strap 11 and / or the curtain hook 12 to the length of the curtain body 10 is between 0.4 and 1. Specifically, the ratio of the length of the curtain hanging strap 11 and / or the curtain hook 12 on each side to the length of that side is between 0.4 and 1, so as to ensure that the projection screen 100 is hung on the wall 01 relatively flatly.

[0037] The projection screen provided by the present application creatively adopts the curtain hanging strap 11 arranged on the back of the projection screen and the curtain hook 12 cooperating with the curtain hanging strap 11, thereby avoiding the problems in the prior art that the curtain is not easy to be flat due to the hanging holes arranged on the curtain and affecting the user product experience.

[0038] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
