[0034] The support curtain 3 of the present invention is provided with a storage body 1, and a storage cavity 11 is provided on the storage body 1, and the support assembly 2 and the curtain 3 are respectively installed in the storage cavity 11. The support assembly 2 and the curtain 3 can be stored together in the storage cavity 11, realizing the integrated storage of the support assembly 2 and the curtain 3, which is convenient for storage or carrying.

[0035] When the support screen 3 of the present invention is actually used, the support assembly 2 and the screen 3 stored in the storage cavity 11 are unfolded from the storage cavity 11, and the support assembly 2 supports the support screen 3 for projection.

[0036] Alternatively, as Figure 2As shown, the storage body 1 is provided with a rotating cover 13, and the rotating cover 13 covers or opens the storage cavity 11. In this embodiment, the opening and closing of the storage cavity 11 is achieved by providing the rotating cover 13. The rotating cover 13 can be installed on the storage body 1 by a rotating shaft, hinge, etc. to achieve rotation, or it can be connected by a flexible material such as silicone to achieve rotation. Specifically, the storage body 1 can be cylindrical. Specifically, the curtain 3 bracket also includes a fixing belt 5, which is sleeved on the storage body 1 to prevent the rotating cover 13 from opening. Specifically, the storage body 1 is provided with a shoulder strap 15 and a handle 16 to facilitate the picking up and carrying of the curtain 3. In other embodiments, a zipper is provided on the storage body 1, and the storage cavity is opened or closed by the zipper. In other embodiments, a cover is provided on the storage body 1, and the cover is closed on the opening of the storage cavity 11 by magnetic attraction.

[0037] Optionally, the support assembly 2 is rotatably mounted in the storage cavity 11. In this solution, the support assembly 2 is rotatably mounted in the storage cavity 11, so as to achieve the purpose of storing the support assembly 2 in the storage cavity 11 and unfolding from the storage cavity 11. Specifically, the support assembly 2 has two groups, and the two groups of support assemblies 2 are respectively mounted at both ends of the storage cavity 11 to achieve stable support of the bracket curtain 3. Specifically, as Figure 3 As shown, each support assembly 2 includes two legs 21, each of which is rotatably mounted in the receiving cavity 11 for storage therein; the two legs 21 can be moved closer together and rotated. In this embodiment, the legs 21 are rotatably mounted in the receiving cavity 11, enabling storage in the receiving cavity 11 and deployment from the receiving cavity 11. The two legs 21 can be moved closer together and rotated, allowing the legs 21 to be spread apart during use and moved closer together before being stored in the receiving cavity 11, making storage convenient.

[0038] Alternatively, as Figures 6 and 7 As shown, mounting portions 12 are provided at both ends of the storage chamber 11, and rotating connectors 17 are rotatably mounted on both sides of the mounting portions 12. Two legs 21 are rotatably mounted on the rotating connectors 17. In this solution, by providing a rotatable rotating connector 17 on the mounting portion 12 and rotatably mounting the two legs 21 on the rotating connectors 17, the legs 21 can be rotated toward each other and rotated to be stored in the storage chamber 11. This has a simple structure and convenient storage of the legs 21.

[0039] Alternatively, as Figures 3 and 4As shown, the support assembly 2 includes a side link 22, which is disposed between the two support legs 21. The two ends of the side link 22 are rotatably connected to the two support legs 21. In this embodiment, by adding a side link 22, the side link 22 is disposed between the two support legs 21, and the two ends are rotatably connected to the two support legs 21. When the support legs 21 are unfolded, the support stability of the support legs 21 can be improved. When folded and stored, the support legs 21 can be folded and stored by rotation. The support legs 21 can be T-shaped or L-shaped.

[0040] Alternatively, as Figure 6 、 Figure 8 、 Figure 9 As shown, the support curtain 3 includes a locking member 4, which includes a locking structure 41. The locking structure 41 is installed on the end of the storage body and is used to lock the support leg 21. The locking structure 41 locks the support leg 21 to prevent the support leg 21 from being folded during use. Specifically, the locking structure 41 can be a bolt, a pull member, a snap member, a magnetic member, etc. For example, when it is a bolt, Figure 8 and Figure 9 As shown, a bolt is threadedly mounted on and passes through the end of the storage body 1. A locking hole 211 is defined in the leg 21, corresponding to the bolt. When the leg 21 is deployed and in a supporting position, the locking member 4 is rotated, and the bolt passes through the end of the storage body 1 and is inserted into the locking hole 211, thereby locking the leg 21 and preventing it from folding during use. Furthermore, due to the provision of the side connecting rod 22, the locking member 4 only locks one of the legs 21, thus preventing both legs 21 from folding.

[0041] Alternatively, as Figure 4 As shown, a bottom bar 31 is provided at the bottom of the curtain 3, and a first connecting member 221 is rotatably mounted on the side connecting rod 22. The ends of the bottom bar 31 are detachably connected to the first connecting member 221. In this embodiment, the bottom bar 31 at the bottom of the curtain 3 is detachably connected to the first connecting member 221. When the curtain 3 is unfolded from the storage chamber 11, it can be fixed to the first connecting member 221, allowing the curtain 3 to remain stably unfolded. When stored, the bottom bar 31 is detached from the first connecting member 221 to store the curtain 3. The connecting rod is rotatably mounted on the side connecting rod 22, which facilitates the connection and adjustment between the connecting rod and the curtain 3 and the folding and storage of the first connecting member 221. Specifically, connectors 311 are provided at both ends of the bottom bar 31, each having a screw hole. The first connecting member 221 is detachably connected to the screw hole via a bolt 221a. Specifically, a handle 312 is provided on the bottom bar 31 to facilitate pulling the curtain 3 out of the storage chamber 11.

[0042] Alternatively, as Figure 5As shown, the support assembly 2 includes a spring 23, one end of which is mounted in the storage cavity 11 and the other end is mounted on the support leg 21. When the support leg 21 is in the unfolded state, the spring 23 is stretched. In this embodiment, by providing the spring 23, the support leg 21 is quickly retracted into the storage cavity 11 due to the elastic force of the spring 23 when folded and stored, making storage quick and convenient.

[0043] Alternatively, as Figure 3 As shown, the support leg 21 has at least two telescopic joints that can be extended and retracted, which can adjust the support height of the support curtain 3. Specifically, each support leg 21 can have two or three telescopic joints.

[0044] Alternatively, as Figures 6 and 7 As shown, a winding rod 14 capable of winding and rotating is installed in the storage chamber 11, and the curtain 3 is mounted on the winding rod 14. In this embodiment, the winding rod 14 is provided to wind and store the curtain 3. Specifically, the winding rod 14 can be provided with a coil spring to automatically rotate and retract the curtain 3.

[0045] The above is a further detailed description of the present invention in conjunction with specific optional embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
