Detailed Description

Please refer to fig. 1 to 3:

the utility model provides a stage curtain folding and unfolding mechanism which comprises a cross beam 1, wherein a sliding groove 101 with an open upper surface and an open lower surface is formed in the cross beam 1, a lead screw 2 is rotatably connected between the left side surface and the right side surface in the sliding groove 101, a sliding block 13 capable of sliding left and right is arranged in the sliding groove 101, a push-pull rod 14 is welded at the bottom of the sliding block 13, a linear motor 3 is installed on the left end surface of the cross beam 1 through a screw, supporting rods 4 are welded at the left end and the right end of the bottom of the cross beam 1, a sliding rod 5 is welded between the supporting rods 4 at the left end and the right end, a plurality of sliding rings 6 capable of sliding left and right are sleeved outside the sliding rod 5, connecting rods 7 are welded at the bottoms of the sliding rings 6, a curtain 9 is hung at the bottoms between the connecting rods 7, a movable pull rod 10 vertically arranged is embedded at the rightmost end in the curtain 9, and a fixed pull rod 11 is welded at the leftmost end at the bottom of the cross beam 1.

Specifically, a plurality of slip rings 6 are uniformly distributed from left to right, the left side surface of the leftmost slip ring 6 is fixedly connected with the right side surface of the support rod 4 at the left end, a spring 8 is fixedly connected between two adjacent left and right connecting rods 7, the bottom of the rightmost connecting rod 7 penetrates through the inside of a curtain 9 and is fixedly connected with the top of a movable pull rod 10, the support rods 4 at the left and right ends are respectively positioned at the left and right sides below the sliding groove 101, the bottom of a push-pull rod 14 is welded with the top of the rightmost slip ring 6, a lead screw 2 penetrates through a sliding block 13 and is in threaded connection with the sliding block 13, the left end of the lead screw 2 penetrates through the left end surface of the cross beam 1 and is in transmission connection with a power output shaft of the linear motor 3, and the fixed pull rod 11 is positioned at the left side of the support rod 4 at the left end, the lower end of the fixed pull rod 11 is positioned at the left side of the curtain 9, and a plurality of pull ropes 12 are pulled between the fixed pull rod 11 and the curtain 9.

According to the above, the linear motor 3 can drive the lead screw 2 to rotate, the rotating lead screw 2 can push the sliding block 13 to slide left and right in the sliding groove 101, the sliding block 13 sliding left and right synchronously drives the rightmost sliding ring 6 to move through the push-pull rod 14, the rightmost sliding ring 6 drives the movable pull rod 10 to move through the connecting rod 7, when the movable pull rod 10 moves right, the movable pull rod 10 can drive the right side of the contracted curtain 9 to move right, when the curtain 9 moves right, the curtain 9 drives the sliding rings 6 in the middle to slide right through the connecting rod 7, because the leftmost sliding ring 6 is fixedly connected with the supporting rod 4, the leftmost sliding ring 6 is fixed, the fixed pull rod 11 pulls the leftmost side of the curtain 9 through the pull rope 12, when the right side of the curtain 9 moves right, the contracted curtain 9 can be unfolded, and when the curtain 9 is unfolded, the spring 8 is elongated and generates a contracted elastic force;

when the sliding block 13 slides to the left, the movable pull rod 10 moves to the left synchronously, and at this time, the spring 8 loses the right pulling force, so that the spring 8 can utilize the elastic force of the contraction to pull the connecting rod 7 to move to the left, and the connecting rod 7 drives the sliding ring 6 and the curtain 9 to move to the left, so that the curtain 9 moving to the left can be contracted.

In summary, by arranging the movable pull rod 10 inside the curtain 9, when the slide block 13 slides to the right, the slide block 13 can synchronously drive the movable pull rod 10 to move to the right through the push-pull rod 14, the rightmost slide ring 6 and the connecting rod 7, so that the curtain 9 which is contracted can be unfolded by the movable pull rod 10 moving to the right, and when the curtain 9 is pulled by the movable pull rod 10, the movable pull rod 10 is vertically arranged, so that all positions of the curtain 9 which moves are uniformly stressed, and the curtain 9 can be unfolded more smoothly and is not easy to be blocked;

through set up spring 8 between each connecting rod 7, spring 8 can be elongated and produce the elasticity of shrink when curtain 9 expandes the back, so when curtain 9 shrink, spring 8 just can utilize the slip ring 6 of a plurality of in the middle of the elasticity pulling to slide towards left in step to avoid between the slip ring 6 too close to and lead to curtain 9 to pile up the winding, and spring 8 utilizes the elasticity of shrink can accelerate the shrink speed of curtain 9, makes the recovery of curtain 9 more smooth.
