[0023] As some operators have unstable business locations, outdoor entertainment equipment needs to be frequently transported, and thus frequently assembled and disassembled. At the same time, servo motors, as the most important power supply equipment in related entertainment equipment, need to be inspected and maintained before daily operations.

[0024] When it is necessary to quickly install the motor body 9 on the entertainment equipment, first insert the motor body 9 into the interior of the fixed shell 3, and then start the drive motor 4 so that the output shaft of the drive motor 4 drives the threaded rod 5 to rotate.

Therefore, the slide 12 will be driven to move toward the motor body 9, and the insertion rod 20 on the push plate 16 will be driven to insert into the slot 17 to preliminarily fix the motor body 9.

[0025] The fixing mechanism 2 is arranged inside the fixing mechanism 1 and is in transmission connection with the fixing mechanism 1.

Connecting rod 1 13 and connecting rod 2 15 gradually approach each other, and the other ends of connecting rod 3 22 and connecting rod 4 24 are rotatably connected to top block 25, thereby driving top block 25 to be pushed toward motor body 9, and making clamping plate 27 close to motor body 9 through transmission rod 26, so as to reinforce motor body 9 for the second time. Fixing mechanism 1 and fixing mechanism 2 are provided with multiple groups, which are dispersedly arranged in a ring shape around motor body 9, and cooperate with each other to fix motor body 9 in all directions.

[0028] The buffer mechanism is arranged between the fixing mechanism 1, the fixing mechanism 2 and the motor body 9 to provide buffer protection for the motor body 9 to prevent the motor body 9 from shaking during the operation of the entertainment device and causing damage to the device; The buffer mechanism includes a spring 19 arranged inside the sleeve 18, the insertion rod 20 is fixedly connected to the spring 19, the other end of the spring 19 is fixedly connected to the inner wall of the sleeve 18, an inner cavity 29 is opened inside the slide 12, the transmission rod 26 extends into the inner cavity 29, the inner cavity 29 is slidably connected with a transmission ring 28, and a spring 30 is fixedly installed between the transmission ring 28 and the inner wall of the inner cavity 29.

[0029] There are multiple groups of fixing mechanism 1 and fixing mechanism 2 respectively, and they are dispersedly arranged in a ring shape. Multiple groups of connecting rods 13 are rotatably connected to lifting ring 1 7, and multiple groups of connecting rods 2 are rotatably connected to lifting ring 2 14.

[0030] A spring 19 is arranged between the insertion rod 20 and the sleeve 18, and a spring 2 30 is arranged in the inner cavity 29, which can offset the shaking of the motor body 9 during the operation of the driving entertainment device, thereby preventing the motor body 9 from being damaged by long-term shaking.

[0031] The heat dissipation mechanism is arranged at the bottom of the fixed shell 3, and utilizes the swinging of the entertainment device to drive the heat dissipation device to dissipate the heat energy generated by the motor body 9 through air cooling, thereby accelerating the cooling of the device; The heat dissipation mechanism includes a plurality of heat dissipation grooves 31 opened on the outer surface of the fixed shell 3, a heat dissipation fin plate 33 is arranged on the lower side of the fixed shell 3, and a plurality of heat-conducting copper tubes 32 are fixedly installed between the heat dissipation fin plate 33 and the fixed shell 3. One end of the heat-conducting copper tube 32 extends to the interior of the fixed shell 3 and is tightly attached to the motor body 9.

Secondly, the motor body 9 installed on the entertainment equipment shakes synchronously with the shaking of the entertainment equipment, so that the slide plate 35 in the slide rail 2 34 reciprocates with the counterweight block 36. When the counterweight block 36 moves toward the center, it will drive the slide plate 35 to squeeze the gas inside the air bag 39, so that the gas is discharged into the dispersion pipe 41 through the connecting pipe 40, and sprayed to the heat-conducting copper tube 32 through the through hole 42, thereby accelerating the flow rate between the heat-conducting copper tube 32, and then performing air cooling and heat dissipation to accelerate the heat dissipation efficiency. When the slide plate 35 moves toward the outer edge of the equipment, the external gas will be sucked into the interior of the air bag 39 through the air inlet 38, thereby completing the gas replenishment, and so on. As the motor body 9 runs, it can be continuously cooled and dissipated by air.

[0034] Instructions for use: When it is necessary to quickly install the motor body 9 on the entertainment equipment, first insert the motor body 9 into the interior of the fixed shell 3, then start the drive motor 4, so that the output shaft of the drive motor 4 drives the threaded rod 5 to rotate. The thread groove on the outer surface of the threaded rod 5 is a bidirectional thread groove. Therefore, when the threaded rod 5 rotates, the two sets of slide rods 6 of the outer surface spiral transmission will move toward each other, so the lifting ring 1 7 and the lifting ring 2 14 will move toward each other synchronously, the lifting ring 1 7 will carry the connecting rod 1 13 to move downward, and the lifting ring 2 14 will carry the connecting rod 2 15 to move upward. The connecting rod 1 13 and the connecting rod 2 15 are both rotatably connected to the slide 12, so the slide 12 will be driven to move toward the motor body 9, and the insertion rod 20 on the push plate 16 will be driven to insert into the slot 17, so as to preliminarily fix the motor body 9; Secondly, the connecting rod 1 13 carries the connecting rod 3 22 to move through the support member 1 21, and the connecting rod 2 15 carries the connecting rod 4 24 to move through the support member 23. The connecting rod 1 13 and the connecting rod 2 15 gradually approach each other, and the other ends of the connecting rod 3 22 and the connecting rod 4 24 are both rotatably connected to the top block 25, so that the top block 25 is driven to advance toward the motor body 9, and the clamping plate 27 is closely attached to the motor body 9 through the transmission rod 26, so that the motor body 9 is reinforced for the second time, and the fixing mechanism 1 and the fixing mechanism 2 are provided with multiple groups, which are dispersedly arranged in a ring shape around the motor body 9, and the motor body 9 is fixed in all directions under mutual cooperation; A spring 19 is arranged between the plug rod 20 and the sleeve 18, and a spring 2 30 is arranged in the inner cavity 29, which can offset the shaking of the motor body 9 during the operation of the driving entertainment device, so as to prevent the motor body 9 from being damaged by the long-term shaking of the motor body 9; The motor body 9 generates a large amount of heat energy during operation. This heat energy can be dissipated through the heat dissipation groove 31, or it can be conducted to the heat dissipation fin plate 33 through the heat-conducting copper tube 32 to accelerate its heat dissipation efficiency. Secondly, the motor body 9 installed on the entertainment equipment shakes synchronously with the shaking of the entertainment equipment, so that the slide plate 35 in the slide rail 2 34 reciprocates with the counterweight block 36. When the counterweight block 36 moves toward the center, it will drive the slide plate 35 to squeeze the gas inside the air bag 39, so that the gas is discharged into the dispersion pipe 41 through the connecting pipe 40, and sprayed to the heat-conducting copper tube 32 through the through hole 42, thereby accelerating the flow rate between the heat-conducting copper tube 32, and then performing air cooling and heat dissipation to accelerate the heat dissipation efficiency. When the slide plate 35 moves toward the outer edge of the equipment, the external gas will be sucked into the interior of the air bag 39 through the air inlet 38, thereby completing the gas replenishment, and so on. As the motor body 9 runs, it can be continuously cooled and dissipated by air.
