[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a controlled stage mechanical lifting platform that is easy to adjust, comprising a support plate 1 and a platform 11, the top of the support plate 1 is fixedly connected to a mounting shell 2, the outside of the mounting shell 2 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly connected to a worm 4, the front and rear ends of the top of the support plate 1 are fixedly connected to fixed blocks 5, the adjacent ends of the two fixed blocks 5 are rotatably connected to two connecting rods 6, the outside of the connecting rods 6 is fixedly connected to a worm gear 8, and the two ends of the connecting rods 6 are fixedly connected to rotating rods 7, the four corners of the bottom of the platform 11 are fixedly connected to support columns 10, and the left and right sides of the top of the support plate 1 are fixedly connected to buffer components 12.

[0024] Specifically, by fixing the mounting shell 2 at the top middle position of the support plate 1, and then fixing the motor 3 at the outside of the mounting shell 2, the motor 3 will not shake during operation, and the overall operation of the structure will be more stable. Then, the motor 3 drives the worm 4 to rotate, so that the worm wheels 8 on both sides start to rotate, and then the connecting rod 6 rotates, and the two ends of the two connecting rods 6 are rotated inside the fixed block 5, so that the connecting rod 6 can drive one end of the rotating rod 7 connected to the two ends to rotate when rotating, so that the other end of the rotating rod 7 moves upward, and then a thrust is generated on the support column 10 to make it slide inside the sleeve rod 9, and connected to the table 11 through the support column 10, so that the table 11 starts to rise and fall, so that the actors can slowly rise and fall during the performance, meet different performance requirements, enrich the stage performance form, and enhance the visual effect of the performance. The buffer component 12 can play a certain buffering role in the lifting and lowering of the table 11, making the lifting and lowering more stable and ensuring safety in use.

[0025] Reference Figure 3 The buffer assembly 12 includes a guide sleeve 1201, which is fixedly connected to the top of the support plate 1. A guide groove 1202 is provided inside the guide sleeve 1201. Two hydraulic rods 1203 are fixedly connected inside the guide groove 1202. A spring 1204 is provided on the outer side of the hydraulic rod 1203. The output ends of the two hydraulic rods 1203 are fixedly connected to a limit plate 1205. The top of the limit plate 1205 is fixedly connected to a support rod 1206. A buffer plate 1207 is fixedly connected to the top, and a rubber pad 1208 is fixedly connected to the top of the buffer plate 1207; one end of the spring 1204 is fixedly connected to the inner bottom of the guide groove 1202, and the other end of the spring 1204 is fixedly connected to the bottom of the limit plate 1205; the outside of the limit plate 1205 is slidably connected to the inner wall of the guide groove 1202, and the outside of the support rod 1206 is slidably connected to the inside of the guide sleeve 1201; the top of the rubber pad 1208 is fixedly connected to the bottom of the table plate 11.

[0026] Specifically, when the table 11 is raised or lowered, the hydraulic rod 1203 is extended or retracted, so that the limit plate 1205 slides inside the guide groove 1202, and then the support rod 1206 slides inside the guide sleeve 1201, so that the spring 1204 produces an extension and retraction effect, and at the same time, the buffer plate 1207 and the rubber pad 1208 connected to the top of the support rod 1206 also begin to move, wherein the rubber pad 1208 is connected to the bottom of the table 11, thereby playing a certain buffering role during the lifting process, making the table 11 more stable when raised or lowered, without violent shaking, thereby ensuring the safety of the performers, and the symmetrically arranged buffer assembly 12 can also play a certain supporting role for the table 11, reduce the load of the motor 3 during operation, and extend the service life of the entire device, and connect the two ends of the spring 1204 to the inner bottom of the guide groove 1202 and the bottom of the limit plate 1205 respectively, so that the spring 1204 will not be offset when extended or retracted, thereby affecting the buffering effect.

[0027] Reference Figure 1 The outer side of the worm 4 is meshingly connected with the outer sides of the two worm wheels 8, and the other end of the worm 4 is rotatably connected to the inside of the support plate 1; the four corners of the top of the support plate 1 are fixedly connected with a sleeve rod 9, and the inside of the sleeve rod 9 is slidably connected to the outside of the support column 10; the outside of the rotating rod 7 is slidably connected to the bottom of the support column 10, and the outside of the rotating rod 7 is slidably connected to the inside of the sleeve rod 9.

[0028] Specifically, the outer side of the worm 4 is meshed with the outer sides of the two worm wheels 8, and the two worm wheels 8 are set to be symmetrical on the left and right, so that the worm 4 can drive the worm wheel 8 to rotate when it rotates, thereby producing a lifting result. The other end of the worm 4 is rotatably connected to the inside of the support plate 1, which can make it more stable when rotating and less prone to shaking. The up and down movement direction of the support column 10 can be limited by the sleeve rod 9, and then the support column 10 is pushed to move by the rotation of the rotating rod 7, so that the platform 11 is raised and lowered to meet different performance needs.

[0029] Working principle: When using this device, first start the motor 3, and the motor 3 drives the worm 4 to rotate, and then drives the worm wheels 8 on both sides to rotate, so that the connecting rod 6 rotates. At this time, the two ends of the two connecting rods 6 rotate inside the fixed block 5, and then drive the rotating rod 7 connected at both ends to rotate, and the other end of the rotating rod 7 moves upward, thereby generating a thrust on the support column 10 to make it slide inside the sleeve rod 9, so that the platform 11 starts to rise and fall, so that the actors can slowly rise and fall during the performance, enriching the stage performance form and enhancing the visual effect of the performance. When the table 11 is lifted or lowered, the two hydraulic rods 1203 in the guide groove 1202 inside the guide sleeve 1201 also begin to extend and retract, thereby pushing the limit plate 1205 to move, thereby driving the spring 1204 to contract or extend, and the limit plate 1205 drives the support rod 1206 to move, so that the buffer plate 1207 and the rubber pad 1208 also move together. At the same time, the rubber pad 1208 is connected to the bottom of the table 11, so that the buffer assembly 12 plays a buffering effect when the table 11 is lifted or lowered, making the lifting more stable without violent shaking, thereby having a better safety effect, and can play a certain supporting role for the table 11, reduce the load of the motor 3 during operation, and extend the overall service life of the device.
