The shaft sleeve 13 is sleeved on the rotating shaft 12. The upper end of the hanging plate 14 is fixedly connected to the shaft sleeve 13. The lower end of the hanging plate 14 is fixedly connected to the curtain main body 3. The telescopic assembly 11 comprises two first support plates 111, a first connecting shaft 1111, two second support plates 112, a second connecting shaft 1121, a first connecting rod one 113, a first connecting rod two 114, a second connecting rod one 115, a second connecting rod two 116, a third connecting rod one 117 and a third connecting rod two 118. The two first support plates 111 are arranged in parallel. The first connecting shaft 1111 is installed on the upper part and the lower part of the first support plate 111 and fixedly connects the two first support plates 111. The two second support plates 112 are arranged in parallel. The second connecting shaft 1121 is installed on the upper part and the lower part of the second support plate 112 and fixedly connects the two second support plates 112. The upper end of the first connecting rod one 113 is rotatably connected to the first connecting shaft 1111 on the upper side. The other end is rotatably connected to the lower end of the second connecting rod two 116 and the third connecting rod two 118. The upper end of the second connecting rod two 116 is rotatably connected to the second connecting shaft 1121 on the upper side.

The lower end of the third connecting rod one 117 is rotatably connected to the middle part of the first connecting rod one 113. The first support plate 111 and the second support plate 112 in the telescopic mechanism 1 play a supporting role. The first connecting rod one 113, the first connecting rod two 114, the second connecting rod one 115, the second connecting rod two 116, the third connecting rod one 117 and the third connecting rod two 118 realize the telescopic function. The structures that need to bear weight such as the rotating shaft 12 and the pulley 15 can be installed on the first support plate 111 and the second support plate 112, so that the structural strength is higher. The design of the pulley 15 can make the telescopic mechanism 1 more smooth and play a supporting role.

[0042] Further, two adjacent telescopic assemblies 11 in left-right direction are connected through a rotating shaft 12, the rotating shaft 12 is connected with the middle part of the first support plate 111 and the second support plate 112, or the rotating shaft 12 passes through the upper part and the lower part of the first support plate 111 and the second support plate 112, the first connecting shaft 1111 and the second connecting shaft 1121 are the end parts of the rotating shaft 12.

[0043] As shown in Figure 5 and Figure 6 , the pulley 15 is rotatably installed on the outer side wall of the first support plate 111 and the second support plate 112; the inner side of the pulley 15 has an outwardly protruding limiting part 151, the diameter of the limiting part 151 is larger than the diameter of the main body of the pulley 15, and the limiting part 151 is located on the inner side of the lower cross beam 23; the width direction of the hanging plate 14 is parallel to the length direction of the shaft sleeve 13, and the lower end of the hanging plate 14 is formed with a connecting groove 141 for connecting the curtain body 3. Since the first support plate 111 and the second support plate 112 have high structural strength, the pulley 15 installed on them is not easy to be separated from the lower cross beam 23 due to the deformation of the two, which is beneficial to improve the service life and safety; the design of the inner limiting part 151 of the pulley 15 can avoid the pulley 15 from being too left or right, which can cause one side of the pulley 15 to be separated from the lower cross beam 23, which is beneficial to improve the stability of the stage curtain during work; the design of the hanging plate 14 direction can make the stage curtain in the retracted state in a natural S shape; when the telescopic assembly 11 is stretched, the curtain body 3 will have a tendency to be straightened, which will exert a horizontal forward or backward offset force on the hanging plate 14 and the shaft sleeve 13, at this time, the design of the limiting part 151 on the pulley 15 can abut against the inner side wall of the upper cross beam 24 after the rotating shaft 12 is slightly offset, thereby limiting the offset of the rotating shaft 12, further improving the stability and safety of the stage curtain during work.

[0044] As shown in Figure 1 and Figure 10As shown, the driving motor 4 is connected with a winding drum 42 through a speed reducer 41, and the winding drum 42 is provided with a spiral groove 421, so that one end of the telescopic mechanism 1 is fixedly connected with the end of the first guide rail 21 or the second guide rail 22, and the other end is a free end. The steel wire rope 5 passes through the first guide rail 21, the transmission mechanism 6 and the second guide rail 22 in sequence and is fixedly connected with the free ends of the two telescopic mechanisms 1. The two ends of the steel wire rope 5 are fixedly connected with the front end and the rear end of the winding drum 42, and the front part of the winding drum 42 is wound with part of the steel wire rope 5. When the curtain main body 3 is closed, the driving motor 4 drives the winding drum 42 to rotate forward, the steel wire rope 5 drives the telescopic mechanism 1 in the first guide rail 21 to move forward, and simultaneously drives the telescopic mechanism 1 in the second guide rail 22 to move backward, until the stage curtain is staggered and closed. At this time, the steel wire rope 5 wound on the front part of the winding drum 42 gradually decreases with the rotation of the winding drum 42, and the steel wire rope 5 is gradually wound on the rear part of the winding drum 42. When the curtain main body 3 is opened, the driving motor 4 drives the winding drum 42 to rotate reversely, the steel wire rope 5 drives the telescopic mechanism 1 in the first guide rail 21 to contract backward, and simultaneously drives the telescopic mechanism 1 in the second guide rail 22 to contract forward. At this time, the steel wire rope 5 on the front part of the winding drum 42 gradually increases with the reverse rotation of the winding drum 42, and the steel wire rope 5 wound on the rear part of the winding drum 42 gradually decreases.

A group of steel wire limiting pieces 63 is also arranged between the adjacent two transmission wheels 61. The central axes of all the limiting rollers 62 are parallel to the horizontal plane. The outer circumferential surfaces of the transmission wheel 61 and the driven wheel 28 are both formed with an annular groove 611. The above-mentioned transmission mechanism 6 can realize the steering of the steel wire rope 5, so that the steel wire rope 5 can move more smoothly. The design of the steel wire limiting piece 63 can make the steel wire rope 5 smoothly enter the annular groove 611 of the transmission wheel 61, avoid the steel wire rope 5 from being separated from the transmission wheel 61, and be beneficial to improving the stability of the stage curtain.

[0046] Further, the first guide rail 21 and the second guide rail 22 are suspended from the grid top through a plurality of suspension ropes, and are fixedly connected with the wall through a plurality of mounting plates. The design of the suspension ropes and the mounting plates can make the first guide rail 21 and the second guide rail 22 more fixedly, and improve the stability of the stage curtain during working.
