[0002] Stage curtains are curtain structures used to cover the stage and are also one of the main components of today's stage. The function of stage curtains is to block the audience's line of sight and facilitate the replacement of personnel and props on the stage. They are generally used in scene transitions of stage plays. Under normal circumstances, the stage curtains are retracted on both sides or above the stage, and the stage curtains on both sides are generally in a wavy folded state.
[0003] The folded stage curtain is achieved by the mechanical tradition of the storage device when controlling the movement of the stage curtain. However, the current folding structure cannot be fully stretched when stretched because it needs to ensure the folding effect when stored, and there is a problem of jamming. If the folding structure is jammed, the stage curtain cannot be fully folded, which affects the folding effect. For this reason, a stage curtain folding chain structure is proposed.

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] Please refer to Figure 1-3 The utility model relates to a folding chain structure for a stage curtain, comprising a fixed top plate 1, a connecting horizontal plate 4 being set up just below the fixed top plate 1, a curtain 10 being detachably connected to the bottom side wall of the connecting horizontal plate 4, one end of the connecting horizontal plate 4 being fixedly connected to a turntable 5, an end of the connecting horizontal plate 4 away from the turntable 5 being fixedly connected to a swivel 6, the turntable 5 being rotatably connected in the swivel 6, an auxiliary horizontal plate 8 being set up on one side of the connecting horizontal plate 4, a fixed column 9 being connected in the auxiliary horizontal plate 8, a pull rod 15 being connected in one end of the fixed column 9, and one end of the pull rod 15 being rotatably connected in the turntable 5 It is dynamically connected to one side wall of the swivel 6, and a suspension rod 7 is fixedly connected to the middle of the top side wall of the turntable 5. The swivel 6 and the turntable 5 are staggered. A movable groove is opened in the middle of the side wall opposite to the fixed top plate 1 and the connecting cross plate 4, and the slider 2 is evenly slidably connected in the movable groove. The bottom side wall of the slider 2 is rotatably connected to the connecting column 3. The connecting column 3 is fixedly connected to the top side wall of one end of the connecting cross plate 4 through its end away from the slider 2, and the suspension rod 7 is rotatably connected to the bottom side wall of the slider 2 in the movable groove through its top end;
[0017] A sliding groove 11 is provided in the middle of the side walls opposite to the auxiliary cross plate 8 and the connecting cross plate 4. The opposite connecting side walls in the sliding groove 11 are fixedly connected to a limiting rod 13, and a moving block 12 is slidably sleeved on the limiting rod 13. The fixed column 9 is detachably connected to one side wall of the moving block 12 through one end thereof. An inner groove is provided in the middle of the fixed column 9, and a spring 14 is fixedly connected to the side wall at one end of the inner groove. One end of the pull rod 15 extends into the inner groove and is fixedly connected to one end of the spring 14.
[0018] The technical effect of this solution is as follows: the control slider 2 slides along the moving groove, driving the connecting transverse plate 4 to move, and at the same time, the spring 14 drives the pull rod 15 to pull the corresponding swivel 6, so that the corresponding two connecting transverse plates 4 are adjusted to an inclined state. As the slider 2 continues to move, the connecting transverse plate 4 in the inclined state will be suppressed to continue to rotate, and the turntable 5 between the two pull rods 15 will be connected to the suspension rod 7, and the corresponding turntable 5 is limited by the suspension rod 7 to rotate in place, so that the connecting transverse plate 4 in the inclined state can be smoothly folded to ensure that the curtain 10 is smoothly stored. In order to ensure smooth folding, sufficient space is reserved between the auxiliary transverse plate 8 and the connecting transverse plate 4 for the connecting transverse plate 4 to move, avoiding space interference and movement interference. At the same time, the fixed column 9 is set to a movable state, so that the fixed column 9 can move with the movement of the connecting transverse plate 4. At the same time, because the pull rod 15 is set to pull the swivel 6, there is no need to preset the connecting transverse plate 4 to a tilted state, but it can be unfolded horizontally to ensure the shielding range of the curtain 10.
[0019] The center point of the swivel 6 is rotatably connected to a docking plate 19, and the docking plate 19 is detachably connected to the middle of the bottom side wall of the turntable 5. The swivel 6 is a semicircular structure, and a rotation groove 16 is provided on the inner wall of the swivel 6. The turntable 5 is rotatably connected in the rotation groove 16. The top edge of the turntable 5 in the rotation groove 16 is fixedly connected to a positioning plate 18, and the top side wall in the rotation groove 16 and near one end is fixedly connected to a baffle 17, and the baffle 17 corresponds to the rotation groove 16.
[0020] The technical effect of this solution is: the docking plate 19 is established to ensure that the turntable 5 is stably connected to the rotating ring 6, and the positioning plate 18 and the baffle 17 connected to the turntable 5 and the rotating groove 16 can limit the rotation to avoid excessive extension or reverse rotation and folding.
[0021] Specifically, when the present invention is used, the front-end auxiliary cross plate 8 is connected to the driver, which drives it to slide along the moving groove through the driver, and drives the corresponding connecting cross plate 4 to move backward through the connecting column 3. During this process, the pulling force on the swivel 6 will be relaxed, so that the spring 14 can pull the pull rod 15 into the inner groove and pull the swivel 6 to move, thereby adjusting the two corresponding connecting cross plates 4 to an inclined state. At this time, the slider 2 continues to move, so that the connecting cross plates 4 can be pushed to continue to fold and store along the inclined state, and finally the curtain 10 is adjusted to a folding structure of a wave-shaped body. Because of the auxiliary pulling of the pull rod 15, the connecting cross plate 4 can be smoothly adjusted to a horizontal state when unfolding, ensuring that the shielding range of the curtain 10 is maximized, and the pull rod 15 can also avoid the anti-stuck effect, ensuring smooth folding.
[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
