Secondly, in order to ensure the performance effect, the lifting part of the lifting stage does not have protective equipment. An automatic lifting stage for preventing people from falling with application number CN2021214590993 includes a workbench, a base and a lifting mechanism. When the workbench is in a lifted state, the baffle flips onto the workbench to protect and warn the performers on the workbench.
[0003] Although the device has the above advantages, it still has the following defects when used:
[0004] 1) When the device is in use, there is no trigger device and it is kept in a real-time open state, which causes a certain amount of obstruction to the surroundings of the actors during the performance, thus affecting the performance effect;
[0005] 2) Although the device can play a protective role, the protective flaps are set around the outside of the workbench, and the protective effect is average. In addition, when an actor falls, the contact with the flaps will cause the center of the device to shift, thus affecting the final stability.

One end of the telescopic rod 7 is fixedly connected to the inside of the slide groove 3, and the other side of the outer surface of the slide plate 4 is fixedly connected to an elastic net 8, and the elastic net 8 is made of existing anti-fatigue materials. One side of the outer surface of the elastic net 8 is fixedly connected to the inside of the slide groove 3.

The touch frame 10 is made of existing pressure-sensitive materials and is electrically connected to the external control circuit. By being set into a frame shape, large-area triggering without dead angles can be performed.
[0026] By setting up an anti-fall mechanism, the touch frame 10 is used to determine the range of the actors on the stage 2. When the safe range is exceeded, the actor steps on the touch frame 10 to generate a trigger signal, and the telescopic rod 7 drives the slide plate 4 and the elastic net 8 to extend and rise, thereby performing anti-fall protection, which will neither block the performance nor cause the overall center deviation.
[0027] Embodiment 2:
[0028] An anchoring assembly 5 is provided on the outside of the skateboard 4, and the anchoring assembly 5 includes a groove 51. The groove 51 is opened on the outer surface of the table plate 2, and the interior of the groove 51 is connected with the interior of the slide groove 3. A traction rope 52 is provided inside the groove 51. The traction rope 52 is made of pressure-resistant and wear-resistant material, and one end of the traction rope 52 is fixedly connected to the outer surface of the skateboard 4.
[0029] The other end of the traction rope 52 is wound and connected with a reel 53, which can collect the traction rope 52 in an orderly manner to prevent the traction rope 52 from being entangled and knotted. The outer surface of the reel 53 is rotatably connected to the inside of the groove 51, and the body of the reel 53 is fixedly connected with a rotating rod 54, which is made of pressure-resistant and wear-resistant material.
[0030] The end of the rotating rod 54 is embedded in the interior of the groove 51 and is rotatably connected. The outer surface of the rotating rod 54 is sleeved with a torsion spring 55. The torsion spring 55 is made of a compression-resistant, wear-resistant and fatigue-resistant material, which can enable the reel 53 to reverse and wind and collect the traction rope 52. The two ends of the torsion spring 55 are fixedly connected to the interior of the groove 51 and the outer surface of the reel 53 respectively.
[0031] Connecting plates 56 are rotatably connected to both sides of the outer surface of the rotating rod 54. The connecting plates 56 can be connected to the rotating rod 54 through bearings. The outer surface of the connecting plate 56 is fixedly connected to a baffle 57. There is a certain gap between the baffle 57 and both sides of the inside of the groove 51 to facilitate rotation. The outer surface of the baffle 57 is movably connected to the inside of the groove 51.
[0032] The outer surface of the baffle 57 is fixedly connected with a protective tube 58, which can provide certain protection for the traction rope 52 and is connected to the baffle 57 to form a linkage. The outer surface of the protective tube 58 is movably connected to the inside of the groove 51, and the protective tube 58 is sleeved on the outer surface of the traction rope 52.
[0033] By providing the anchoring assembly 5, the rising slide plate 4 can be anchored by utilizing the traction rope 52, and the stability of the slide plate 4 can be improved by utilizing the triangular stabilization principle. Meanwhile, the obliquely straightened traction rope 52 can also provide preliminary cushioning and support for the falling actor.
[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0035] During operation; when an actor performs on the stage 2, if he steps on the touch frame 10, the resistance and current of the circuit will change, forming a pressure-sensitive trigger signal. Then, when the actor's limbs are directly above the skateboard 4, the rangefinder 6 measures the distance from the actor's limbs and the set value (the set value is specifically set according to the actor's rise, and the measured value is less than or equal to the set value, which is considered to be in compliance. At the same time, it serves as the final judgment of the movement of the skateboard 4 to avoid some dance movements with a large range, which may lead to misjudgment of the touch frame 10, or when a fall occurs, the actor does not step on the touch frame 10). The output end of the telescopic rod 7 is extended and retracted, so that the skateboard 4 pulls the elastic net 8 The slide plate 4 rises to protect the edges of the platform 2 to prevent the actors from falling and to avoid the problem of center of gravity shifting. At the same time, when the slide plate 4 rises, it pulls one end of the traction rope 52 to follow the movement. Then, on the one hand, the traction rope 52 drives the rotating rod 54 to rotate through the reel 53, and compresses the torsion spring 55, so that after the slide plate 4 is reset, the reel 53 winds and collects the traction rope 52. On the other hand, the traction rope 52 tilts during movement and, through the action of the protective tube 58, drives the baffle 57 to follow the synchronous movement, so that the baffle 57 keeps protecting the other end of the traction rope 52 and the reel 53 in real time.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
