Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model.

[0026] Example 1

[0027] Refer to Figures 1-5, A stage curtain lifting device, comprising a stage floor 2. An inner side at the upper end of the stage floor 2 is provided with a stage curtain retracting and releasing mechanism 3. An inner side of the stage curtain retracting and releasing mechanism 3 is provided with a stage curtain body 6. The other end of the stage curtain body 6 is provided with a lifting and pulling frame 1. Both ends of the lifting and pulling frame 1 are provided with curtain lifting adjustable arm rods 4 on the stage floor 2. An inner end of the curtain lifting adjustable arm rod 4 is provided with a curtain lifting driving mechanism 5 on the stage floor 2. The stage curtain retracting and releasing mechanism 3 and the curtain lifting driving mechanism 5 are electrically connected to an external controller through connecting wires. When in use, the curtain lifting driving mechanism 5 on the stage floor 2 drives the curtain lifting adjustable arm rod 4 to rotate. The curtain lifting adjustable arm rod 4 then drives the lifting and pulling frame 1 to rotate and turn over. The lifting and pulling frame 1 then pulls the stage curtain body 6 in the stage curtain retracting and releasing mechanism 3 to lift, so that the stage curtain body 6 is completely lifted and unfolded. When the stage curtain body 6 has a longer length, the curtain lifting adjustable arm rod 4 can automatically extend to change the overall flipping height, so as to meet the requirement of lifting and using stage curtain bodies 6 of different lengths.

[0028] In the present utility model, the lifting and pulling frame 1 includes a hollow sleeve frame 11, a curtain mounting screw 12, a curtain mounting groove 13 and a curtain pulling rod 14. The inner side at the lower end of the hollow sleeve frame 11 is sleeved with the curtain pulling rod 14. The inner side of the curtain pulling rod 14 is provided with the curtain mounting groove 13. The inner side of the curtain mounting groove 13 is provided with the curtain mounting screw 12 on the curtain pulling rod 14. The hollow sleeve frame 11 is connected to the curtain lifting adjustable arm rod 4. The curtain pulling rod 14 is connected to one end of the stage curtain body 6 through the curtain mounting screw 12. The hollow sleeve frame 11 of the lifting and pulling frame 1 is installed and connected to the curtain lifting adjustable arm rod 4 through screws. Thus, when the curtain lifting adjustable arm rod 4 flips, it can drive the hollow sleeve frame 11 to flip. Due to the curtain mounting groove 13 inside the curtain pulling rod 14 of the hollow sleeve frame 11, one end of the stage curtain body 6 can be correspondingly sleeved and placed. After placement, the stage curtain body 6 can be effectively fixed through the curtain mounting screw 12 in the curtain mounting groove 13, so as to prevent the lifted stage curtain body 6 from falling off.

[0029] In the present utility model, the curtain flipping adjustable arm rod 4 includes a rotating shaft rod 41, a flipping arm plate housing 42, and an electric telescopic cylinder 43. Rotating shaft rods 41 are arranged on both sides of the rotating end of the flipping arm plate housing 42, and an electric telescopic cylinder 43 is arranged inside the lifting end of the flipping arm plate housing 42. The electric telescopic cylinder 43 is connected to the flipping pulling frame 1. The flipping arm plate housing 42 is connected to the stage floor 2 through the rotating shaft rod 41, and the rotating shaft rod 41 is connected to the curtain flipping driving mechanism 5. The flipping arm plate housing 42 of the curtain flipping adjustable arm rod 4 is movably connected to the stage floor 2 through the rotating shaft rod 41, so that the flipping arm plate housing 42 can rotate with limited position. The rotating shaft rod 41 is connected to the curtain flipping driving mechanism 5. In this way, when the curtain flipping driving mechanism 5 drives the rotating shaft rod 41 to rotate, the rotating shaft rod 41 can drive the flipping arm plate housing 42 to rotate, and the flipping arm plate housing 42 can drive the flipping pulling frame 1 installed through the electric telescopic cylinder 43 to flip. When the electric telescopic cylinder 43 extends, the height position of the flipping pulling frame 1 can be changed, thereby effectively changing the overall flipping height and meeting the flipping requirements of the stage curtain body 6 with different lengths.

[0030] In the present utility model, mounting grooves for the stage curtain retracting and deploying mechanism 3, the curtain flipping adjustable arm rod 4, and the curtain flipping driving mechanism 5 are correspondingly arranged inside the upper end of the stage floor 2, so that they can be correspondingly installed and used.

[0031] Working principle: During use, the curtain flipping driving mechanism 5 on the stage floor 2 drives the curtain flipping adjustable arm rod 4 to rotate. The curtain flipping adjustable arm rod 4 drives the flipping pulling frame 1 to rotate and flip. The flipping pulling frame 1 pulls the stage curtain body 6 in the stage curtain retracting and deploying mechanism 3 to flip, so that the stage curtain body 6 is completely flipped and unfolded. When the stage curtain body 6 has a longer tablecloth, the curtain flipping adjustable arm rod 4 can automatically extend to change the overall flipping height, so as to meet the flipping use of the stage curtain body 6 with different lengths.
