Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7 , the present utility model discloses a stage curtain conducive to assembly, including a column 1, a transmission belt 2 and a main curtain body 3. The number of the columns 1 is two and the two columns 1 are symmetrically arranged. An internally movable lifting seat 14 is arranged inside the column 1. A turntable 15 is rotatably arranged at the top of the lifting seat 14. A motor for driving the turntable 15 is arranged inside the lifting seat 14.

[0027] The transmission belt 2 is sleeved on the two turntables 15. Two guide wheels 16 are movably arranged at the top of the lifting seat 14 and are respectively located on both sides of the transmission belt 2. An adjusting roller 17 located on one side of the turntable 15 is movably arranged at the top of the lifting seat 14. The main curtain body 3 is movably arranged on both sides of the transmission belt 2. The turntable 15 is a pulley and has a slot inside, which can prevent the transmission belt 2 from shaking up and down, making the transmission process of the transmission belt 2 more stable. Please refer to Figure 1 and Figure 3, the interior of the column 1 is U-shaped. During use, by controlling the forward and reverse rotation of the first lead screw 12, the lifting seat 14 can be driven to move up and down. By controlling the first lead screw 12 to lower the lifting seat 14, this design method facilitates the user to install or separate the transmission belt 2 from the turntable 15. After the transmission belt 2 and the turntable 15 are installed, rotate the transmission belt 2 to align the positions of the sliding grooves 21 at the tops of both sides of the transmission belt 2 in the middle part. Then, connect the two curtain bodies 3 to the sliding grooves 21, positioning grooves 22, and positioning posts 19 through the hooks 31. After the curtain bodies 3 are installed, rotate the first lead screw 12 to raise the lifting seat 14 to the proper position and then it can be used. Conversely, the transmission belt 2 and the curtain bodies 3 can be disassembled, and finally, the bolts inside the mounting plate 11 are disassembled, and then the column 1 can be moved.

[0028] Specifically, the two curtain bodies 3 are staggered from each other. A plurality of hooks 31 are equidistantly arranged at the top of the curtain body 3. A ball 32 is movably embedded at one end of the hook 31 away from the curtain body 3. The setting of the ball 32 can reduce the friction between the hook 31 and the sliding groove 21, avoid the situation where the hook 31 gets stuck, and make the unfolding and storage processes of the curtain body 3 more stable and flexible.

[0029] Specifically, sliding grooves 21 and positioning grooves 22 located on one side of the sliding grooves 21 are formed at the tops of both sides of the transmission belt 2. The length of the sliding groove 21 is greater than the length of the curtain body 3. A positioning post 19 is fixedly arranged at the top of the lifting seat 14 on one side of one of the guide wheels 16. The hooks 31 at both ends of the top of the curtain body 3 are respectively hung inside the positioning post 19 and the positioning groove 22, and the hooks 31 in the middle part of the top of the curtain body 3 are all hung inside the sliding groove 21. The positioning groove 22 and the positioning post 19 are respectively used to limit the hooks 31 at both ends of the top of the curtain body 3, so as to drive the curtain body 3 to unfold and store when the transmission belt 2 rotates. The two curtain bodies 3 are staggered from each other. When the turntable 15 rotates, according to the rotation direction of the turntable 15, the transmission belt 2 drives the two curtain bodies 3 to move relatively to unfold or move away from each other to store. With the setting of the two lifting seats 14, only a motor needs to be installed on one of the lifting seats 14, and the manufacturing cost is lower.

[0030] Specifically, a first lead screw 12 that is rotationally arranged inside the column 1 and is threadedly sleeved inside the lifting seat 14 is provided. A rotating cylinder 13 is arranged at the bottom of the first lead screw 12. A through hole for exposing the rotating cylinder 13 is formed at the bottom of one side of the column 1. Refer to Figure 2, a plurality of levers are provided on the rotating drum 13, which facilitate the rotation of the screw rod 12 by the lever, and by controlling the number of the levers, the angle of each rotation of the screw rod 12 can be controlled, which facilitates the user to control the rotation speed of the two screw rods 12 and realize the synchronous rotation of the two screw rods 12, and the two turntables 15 are connected by a transmission belt 2. When there is a small difference in the rotation speed of the two screw rods 12, the transmission belt 2 can withstand a small misalignment of the height levels of the two turntables 15 without affecting the use. The rotation accuracy of the two screw rods 12 can be maximized by the lever, and manual rotation of the screw rod 12 is more convenient and energy-saving, and the manufacturing cost is greatly reduced.

[0031] Specifically, a waist-shaped hole 141 is provided on the top of the lifting seat 14, and a nut roller 171 is provided at the bottom of the adjusting roller 17, the bottom of which passes through the waist-shaped hole 141 and extends to the inside of the lifting seat 14. A second screw rod 142 is rotatably provided inside the lifting seat 14, and the surface of the second screw rod 142 is threadedly sleeved with the internal thread of the nut roller 171. An adjusting shaft 18 is also rotatably provided inside the lifting seat 14, and one end of the adjusting shaft 18 and the second screw rod 142 are respectively provided with bevel gears that mesh with each other. The mother roller 171 is also waist-shaped, but the length of the nut roller 171 is smaller than the waist-shaped hole 141. Using a longer transmission belt 2 can facilitate the connection with the two turntables 15. When the transmission belt 2 is installed, it is too long and the fit with the turntable 15 is poor. By rotating the adjusting shaft 18 to drive the screw rod 2 142 to rotate, the nut roller 171 is moved inside the waist-shaped hole 141 by the rotation of the screw rod 2 142. At the same time, the nut roller 171 drives the adjusting roller 17 to contact the transmission belt 2, tightening the transmission belt 2, so that the transmission belt 2 is more tightly connected to the turntable 15.

[0032] Specifically, at least one mounting plate 11 is provided at the bottom of one side of the column 1 , and the column 1 can be fixed to the stage with bolts via the mounting plate 11 .

[0033] In summary, the stage curtain that is easy to assemble, the lifting seat 14 that can be raised and lowered cooperates with the adjusting roller 17 for tensioning the transmission belt 2, which facilitates the installation and disassembly of the transmission belt 2. The curtain body 3 is hung on the transmission belt 2, which makes assembly and disassembly more convenient, and on-site construction is more convenient and quicker, and transportation is also more convenient and the space occupied is greatly reduced. The two sides of the transmission belt 2 are limited by two guide wheels 16 to be close to each other, so that the two curtain bodies 3 are more closely fitted after being unfolded, and the shielding effect is better, which meets the needs of stage use, has a simple and compact structure, is conducive to processing and production, meets economic benefits, and has broad application prospects.
