[0002] With social development and the improvement of people's living standards, people's demands for entertainment experiences are also increasing. Projectors, as an important large-screen display device, are widely used in e-sports, home theaters, business meetings, education and training, and other fields. However, most existing projectors and their accompanying projection screens are fixed in place, making it difficult to change their location once installed. This means that projectors cannot be easily moved to adapt to different viewing environments or venues. This fixed installation method not only limits user flexibility but also necessitates rearranging the equipment in different situations to meet viewing needs, thus reducing the user experience. For example, during outdoor activities or impromptu gatherings, a quick and convenient viewing environment needs to be set up, but existing projectors and screens cannot meet this requirement. While some portable projector products have emerged, these products typically only address the issues of small size and portability, while still falling short in terms of projection effect, stability, and compatibility with different screens.

[0003] Therefore, designing a solution that is both easy to move and has a good projection effect has become a pressing technical challenge. Utility Model Content

[0035] With social development and the improvement of people's living standards, people's demands for entertainment experiences are also increasing. Projectors, as an important large-screen display device, are widely used in e-sports, home theaters, business meetings, education and training, and other fields. However, most existing projectors and their accompanying projection screens are fixed in place, making it difficult to change their location once installed. This means that projectors cannot be easily moved to adapt to different viewing environments or venues. This fixed installation method not only limits user flexibility but also necessitates rearranging the equipment in different situations to meet viewing needs, thus reducing the user experience. For example, during outdoor activities or impromptu gatherings, a quick and convenient viewing environment needs to be set up, but existing projectors and screens cannot meet this requirement. While some portable projector products have emerged, these products typically only address the issues of small size and portability, while still falling short in terms of projection effect, stability, and compatibility with different screens.

[0036] Therefore, designing a solution that is both easy to move and has a good projection effect has become a pressing technical challenge.

[0037] The following detailed description of the overall structure, working principle, and technical effects of the curtain support structure provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0038] Please refer to Figures 1-5 The curtain support structure provided in this embodiment includes a mounting rod 10, a curtain support rod 20, and a curtain 30. The mounting rod 10 has a receiving cavity 101 inside, and the receiving cavity 101 is connected to one end of the mounting rod 10. The surface of the mounting rod 10 has a groove 102. The curtain support rod 20 is rotatably disposed in the groove 102. The curtain 30 and the curtain support rod 20 are detachably connected. The curtain 30 is used to be stored in the receiving cavity 101 when separated from the curtain support rod 20.

[0039] Specifically, the mounting rod 10 is a straight rod structure. A receiving cavity 101 is located inside the mounting rod 10 along its length and extends through one end of the mounting rod 10. The other end of the mounting rod 10 is used to mount the projector. The screen 30 can be inserted into the receiving cavity 101 for storage after being rolled up. Directly storing the screen 30 within the mounting rod 10 facilitates subsequent installation, use, and storage, making it more convenient to use. Furthermore, the surface of the mounting rod 10 has a groove 102, which is located along its length. The screen support rod 20 is rotatably mounted within the groove 102. When the screen 30 is needed, the screen support rod 20 is rotated out of the groove 102, making it perpendicular to the mounting rod 10. Then, the screen 30 is removed from the receiving cavity 101 of the mounting rod 10 and installed on the screen support rod 20. Finally, the screen 30 is unfolded for projection. Overall, it is more convenient to use.

[0040] In this embodiment, the curtain 30 includes a storage box 31 and a fabric body 32. The top ends of the storage box 31 and the fabric body 32 are connected. The fabric body 32 is a flexible structure and can be rolled up inside the storage box 31. Specifically, the storage box 31 includes a box body 311, a driver 312, and a shaft 313. The driver 312 and the shaft 313 are both installed inside the box body 311. The driver 312 and the shaft 313 are connected, and the shaft 313 is connected to the fabric body 32. The shaft 313 is used to drive the fabric body 32 to rotate under the drive of the driver 312, so that the fabric body 32 is wrapped around the shaft 313 and thus stored inside the box body 311.

[0041] Furthermore, to prevent the fabric 32 from being unable to be recycled in the event of a power outage, the storage box 31 in this embodiment also includes a manual pulley and a rope. The manual pulley is installed inside the box 311 and is connected to the end of the shaft 313. The rope is set in a vertical direction and is connected to the manual pulley. Pulling the rope rotates the manual pulley, which in turn drives the shaft 313 to rotate, thereby achieving the purpose of retracting the fabric 32.

[0042] It should be noted that the screen 30 also includes a baffle 33. Both ends of the storage box 31 are connected to the baffle 33. The baffle 33 is a square plate structure. The shape of the baffle 33 is adapted to the shape of the receiving cavity 101, so that after the screen 30 is stored in the receiving cavity 101, the baffle 33 can completely cover the opening of the receiving cavity 101, so that the screen 30 can be better stored in the receiving cavity 101.

[0043] In this embodiment, in order to facilitate the taking and putting away of the screen 30, the side of the baffle 33 away from the storage box 31 is provided with a first pull strap 40; when it is necessary to take out the screen 30, the screen 30 can be taken out smoothly by simply pulling the first pull strap 40.

[0044] In other embodiments, the baffle 33 may also be elastically disposed within the receiving cavity 101. For example, by providing an elastic element, the curtain 30 can be ejected from or stored in the receiving cavity 101 when the baffle 33 is pressed. No specific limitation is made here.

[0045] It should also be noted that, to further ensure the stability of the screen 30 during projection, the screen support structure also includes a first buckle 50 and a second buckle 60. The first buckle 50 is located on the screen support rod 20, and the second buckle 60 is located on the bottom edge of the fabric 32. The second buckle 60 is used to engage with the first buckle 50 when the fabric 32 is unfolded. Specifically, the first buckle 50 is installed at the end of the screen support rod 20 near the mounting rod 10. The first buckle 50 engages with the second buckle 60 when the fabric 32 is open, thereby temporarily fixing the fabric 32 during projection, preventing the fabric 32 from shaking during projection, ensuring normal use of the projector, and improving the viewing experience.

[0046] In this embodiment, both the first latch 50 and the second latch 60 are V-shaped structures, and their installation directions are opposite, allowing them to snap together. In other embodiments, the shapes of the first latch 50 and the second latch 60 can be adjusted according to actual usage, and are not specifically limited here.

[0047] Understandably, in order to facilitate the taking and putting away of the curtain support rod 20, the curtain support rod 20 is provided with a second pull strap 70.

[0048] In an optional embodiment, the screen support structure further includes a clamp 80, which is rotatably connected to the end of the mounting rod 10, and the clamp 80 is used to clamp the projector.

[0049] The clamp 80 includes a clamp ring and a connecting part. The two ends of the connecting part are connected to the clamp ring and the mounting rod 10, respectively. The clamp ring is used to engage with the projector. The connecting part and the mounting rod 10 are rotatably connected by a rotating shaft.

[0050] In this embodiment, the curtain support structure also includes a rotating component 90 and a bottom support 100. The bottom support 100 is arranged in a vertical direction, the rotating component 90 is disposed at the top of the bottom support 100, and the mounting rod 10 is rotatably connected to the top of the bottom support 100 through the rotating component 90.

[0051] Furthermore, to ensure the stability of the bottom support 100, the bottom support 100 includes a telescopic rod 110 and a tripod 120. The top end of the telescopic rod 110 is connected to the mounting rod 10, and the bottom end of the telescopic rod 110 is connected to the tripod 120. The bottom of the tripod 120 is equipped with pulleys, which can slide the bottom support 100 when it is moved, making the overall movement more effortless and convenient.

[0052] Specifically, the rotating component 90 is a rotating shaft. The top of the bottom bracket 100 is provided with a rotating groove, the middle part of the mounting rod 10 is located in the rotating groove, and the rotating shaft passes through the rotating groove and the mounting rod 10. Rotating the rotating shaft can lock or loosen the mounting rod 10 and the bottom bracket 100. Of course, the end of the rotating shaft can also be provided with a knob to facilitate rotating the rotating shaft.

[0053] When angle adjustment is required, turn the knob to drive the shaft to rotate, loosening the connection between the mounting rod 10 and the bottom bracket 100. Then adjust the mounting angle of the mounting rod 10. After adjustment, turn the knob in the opposite direction to drive the shaft to rotate in the opposite direction, thereby locking the mounting rod 10 and the bottom bracket 100.

[0054] This embodiment also provides a projection device, including a projector and a screen support structure, wherein the projector and the clamp are connected at an angle.

[0055] In summary, this embodiment provides a screen support structure and a projection device. The screen support structure includes a mounting rod 10, a screen support rod 20, and a screen 30. The mounting rod 10 has a receiving cavity 101 inside, and the receiving cavity 101 is connected to one end of the mounting rod 10. The surface of the mounting rod 10 has a groove 102. The screen support rod 20 is rotatably disposed in the groove 102. The screen 30 and the screen support rod 20 are detachably connected.
