[0002] The stage is the space provided for actors to perform in a theater. It can focus the audience's attention on the actors' performance and achieve an ideal viewing effect. The stage is usually composed of one or more platforms. The types of stages include proscenium stage, extended stage and circular stage. Stage art refers to the art performed on the stage, which mainly includes drama, folk art, music, dance, acrobatics, magic, martial arts and other art forms.

[0003] In order to achieve better performance effects, existing stages are all equipped with lifting functions. However, when actors perform on stage, they do not have better rotation functions, which cannot well meet the diverse performance requirements and thus fail to achieve ideal performance effects. In addition, most stage lifts use hydraulic cylinders to drive the scissor frame to fold for height adjustment, but the bottom of the lifting platform is usually unevenly stressed, making the platform easy to shake during the lifting process, which can cause people to stand unstable and fall, posing certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the above-mentioned platform does not have a better rotation function and cannot well meet the requirements of diverse performing arts, thus failing to achieve the ideal performance effect. In addition, the bottom of the lifting platform is usually unevenly stressed, which makes the platform easy to shake during the lifting process, causing people to stand unstable and fall, posing certain safety hazards. Therefore, an adjustable lifting stage equipment is proposed.

The guardrail 21 installed on the top of the lifting platform 2 can protect the performers. When the height of the lifting platform 2 needs to be adjusted, the second motor 5 is started to drive the mounting rod 151 to rotate, and the worm 53 on the surface of the mounting rod 15 engages with the worm wheel 16 on the surface of the movable rod 15, so that it drives the screw 17 to rotate. The rotation of the screw 17 causes the threaded sleeve 22 to move on its surface, so that the height of the lifting platform 2 is adjusted. At the same time, since the four corners of the lifting platform 2 are subjected to force at the same time, the lifting platform 2 can be made more stable during the lifting process.
