[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0029] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0030] Embodiment 1

[0031] A lifting stage with an ejection function, as Figures 1-4 shown, includes a box body 1. Specifically, the position where the box body 1 is set is the opening position reserved in the stage. The height of the top surface of the opening reserved on the stage is the same as the height of the top surface of the box body 1. A plurality of vertically upward lifting columns 2 are arranged in the box body 1. Specifically, the lifting columns 2 are pneumatic lifting columns and are all externally connected with a high-pressure gas storage tank and can instantly extend to a set length. The top ends of the lifting columns 2 are connected with a support frame 3. The top of the support frame 3 is fixedly connected with a lifting plate 4. A vertical guiding track 5 is arranged on the inner wall of the box body 1. A counterweight 6 is slidably connected along the vertical direction in the guiding track 5. Pulleys 7 are arranged above the counterweight 6 at the top end of the inner wall of the box body 1. Specifically, the pulleys 7 are fixed pulleys. A cable 8 is connected to the edge of the support frame 3. The cable 8 bypasses the pulley 7 and is connected to the counterweight 6.

[0032] Please refer to Figures 2-4, a boss 9 is fixedly connected to the edge of the support frame 3, and a connecting ring 10 capable of being connected to the cable 8 is fixedly connected to the boss 9. The boss 9 at the edge of the support frame 3 serves to limit the further upward movement of the support frame 3, enabling the lifting plate 4 to stop instantly when it rises to an appropriate height, preventing the lifting plate 4 from rising above the top surface of the box body 1. When the top surface of the boss 9 contacts the box body 1, the top surface of the lifting plate 4 is flush with the top surface of the box body 1, avoiding uneven protrusions on the stage, effectively enhancing the aesthetic degree of the stage, and at the same time being able to further ensure the safety of the actors and prevent the actors' feet from getting stuck in the gap between the lifting plate 4 and the box body 1.

[0033] Please refer to Figures 2-4 , the lifting columns 2 are pneumatic telescopic columns, and one is provided at each of the four corners inside the box body 1. The number of counterweight blocks 6 is the same as the number of lifting columns 2. The lifting columns 2 provided at the four corners inside the box body 1 can make the lifting of the lifting plate 4 more stable, effectively increasing the stability during the lifting process of the lifting plate 4. Guide blocks 11 are fixedly connected to the four corners of the support frame 3, and the guide blocks 11 are slidably connected to the vertical frames inside the box body 1. The guide blocks 11 at the four corners of the support frame 3 play a role in further guiding the lifting and lowering of the lifting plate 4, stabilizing the four corners of the lifting plate 4, and enabling the lifting plate 4 to lift and lower more smoothly and smoothly under the drive of the lifting columns 2.

[0034] Embodiment 2

[0035] A lifting stage with an ejection function, as Figures 1-4 shown. Based on Embodiment 1, the difference from Embodiment 1 is that after the door 12 of the box is opened, the actor can smoothly enter the inside of the box body 1 without entering the box body 1 from above the box body 1, enabling the actor to enter the box body 1 more smoothly during the performance. And the external staff can conveniently observe the gestures of the actors inside the box body 1 through the observation window 13, and then cooperate with the actors inside the box body 1 to eject and lift the actors at the appropriate time. Observation windows 13 are also provided on the side of the box body 1. The observation window 13 on the side of the box body 1 and the observation window 13 on the door 12 are at the same height. The observation window 13 provided on the side of the box body 1 can also observe the situation of the actors inside the box body 1, enabling the staff in multiple directions outside the box body 1 to observe the situation inside the box body 1 and communicate with the actors inside the box body 1 through gestures.

[0036] The working principle of the present utility model is as follows: when the lifting column 2 contracts, the lifting plate 4 descends. After the actor opens the box door 12 and enters the interior of the box body 1, and closes the box door 12, the actor inside the box body 1 communicates with the external staff through gestures via the observation window 13 to confirm the ejection. The high-pressure gas storage tank releases high-pressure gas to multiple lifting columns 2, and the lifting columns 2 quickly extend. Multiple counterweights 6 fall along the guiding track 5 under their own gravity. The gravity of the counterweights 6 is transmitted to the support frame 3 through the cable 8 and the pulley 7, applying an upward force to the support frame 3, further causing the lifting plate 4 to quickly rise, achieving the performing effect of quickly making the actor appear from below the stage. The lifting column 2 is self-locked after the lifting plate 4 rises to an appropriate height. After the actor rises, the lifting plate 4 locks in height, enabling the actor to move freely on the stage without worrying about stepping on the lifting plate 4. When it is not necessary to eject and lift the actor, the slow rise of the lifting column 2 can also cause the lifting plate 4 to slowly rise and slowly lift the actor.

[0037] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed. However, as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
