[0037] The fixing mechanism 1 includes a lifting ring 1 7 arranged on the upper side of the fixed shell 3, and a lifting ring 2 14 is arranged on the lower side of the fixed shell 3.

[0040] As some operators have unstable business locations, outdoor entertainment equipment needs to be frequently transported, and thus frequently assembled and disassembled.

[0042] The second fixing mechanism is arranged inside the first fixing mechanism and is in transmission connection with the first fixing mechanism. When the first fixing mechanism completes the preliminary fixation of the motor body 9, the second fixing mechanism is driven to operate, thereby strengthening the fixing effect of the motor body 9.

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 both rotatably connected to top block 25, thereby driving top block 25 to advance toward motor body 9, and making splint 27 close to motor body 9 through transmission rod 26, thereby reinforcing motor body 9 for the second time, and fixing mechanism 1 and fixing mechanism 2 are provided with multiple groups, which are dispersedly arranged in a ring around motor body 9, and cooperate with each other to fix motor body 9 in all directions.

[0046] The buffer mechanism is provided 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;

[0047] The buffer mechanism includes a spring 19 arranged inside the sleeve 18, an insert 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, a transmission rod 26 extends into the interior of the inner cavity 29, a transmission ring 28 is slidably connected to the interior of the inner cavity 29, and a spring 2 30 is fixedly installed between the transmission ring 28 and the inner wall of the inner cavity 29.

[0048] There are multiple sets of fixing mechanism 1 and fixing mechanism 2, which are distributed in a ring shape. Multiple sets of connecting rods 13 are rotatably connected to lifting ring 1 7, and multiple sets of connecting rods 2 are rotatably connected to lifting ring 2 14.

[0049] A spring 19 is provided between the insertion rod 20 and the sleeve 18, and a spring 2 30 is provided in the inner cavity 29, which can offset the shaking of the motor body 9 during the operation of the driving entertainment equipment, thereby preventing the motor body 9 from being damaged by long-term shaking.

[0050] The heat dissipation mechanism is arranged at the bottom of the fixed shell 3, and uses the swing 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;

[0051] The heat dissipation mechanism includes multiple groups of heat dissipation grooves 31 opened on the outer surface of the fixed shell 3, and a heat dissipation fin plate 33 is provided on the lower side of the fixed shell 3. Multiple groups 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.

[0052] A second slide rail 34 is fixedly installed on the lower end surface of the heat dissipating fin plate 33, and a slide plate 35 is slidably connected to the inside of the second slide rail 34.

[0053] 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 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 36. When the counterweight 36 moves toward the center, it drives 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.

[0054] 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, and 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 with spiral transmission on the outer surface will move toward each other, so the lifting ring 1 7 and the lifting ring 2 14 will move toward each other synchronously, and the lifting ring 1 7 will carry the connecting rod 13 to move downward, and the lifting ring 2 14 will carry the connecting rod 2 15 to move upward. The connecting rod 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 to preliminarily fix the motor body 9;

[0055] Second connecting rod 13 is carried by support 21 to displace connecting rod 22, connecting rod 15 is carried by support 23 to displace connecting rod 24, connecting rod 13 and connecting rod 15 gradually close, the other end of connecting rod 22 and connecting rod 24 are rotatably connected with the top block 25, so as to drive the top block 25 to advance to the motor body 9, and make the clamping plate 27 close to the motor body 9 through the transmission rod 26, and the motor body 9 is secondly reinforced, and the fixing mechanism one and the fixing mechanism two are provided with multiple groups, which are annularly and dispersedly arranged around the motor body 9, and the motor body 9 is fixed in all directions under the cooperation of the fixing mechanism one and the fixing mechanism two;

[0056] And the spring 19 is arranged between the inserting rod 20 and the sleeve 18, and the spring 30 arranged in the inner cavity 29 can offset the shaking of the motor body 9 during the driving of the entertainment device, so as to avoid damage to the motor body 9 caused by long-time shaking of the motor body 9;

[0057] A large amount of heat energy is generated in the motor body 9 during operation, which can be dissipated through the heat dissipation groove 31, or conducted to the heat dissipation fin 33 through the heat conduction copper pipe 32 to accelerate the heat dissipation efficiency, and the motor body 9 installed on the entertainment device shakes synchronously with the shaking of the entertainment device, so that the sliding plate 35 in the sliding rail 34 reciprocates with the counterweight 36, and when the counterweight 36 displaces to the center, the sliding plate 35 is driven to extrude the gas in the air bag 39, so that the gas is discharged into the dispersion pipe 41 through the communication pipe 40, and is sprayed to the heat conduction copper pipe 32 through the through hole 42, thereby accelerating the flow rate between the heat conduction copper pipes 32, and then air cooling is carried out to accelerate the heat dissipation efficiency, and when the sliding plate 35 displaces to the edge of the device, the gas outside is sucked into the air bag 39 through the air inlet hole 38, so as to complete the gas supplement, so as to continuously air cool and dissipate heat for the motor body 9 during operation.

[0058] The above is only the preferred specific embodiment of the present application; however, the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
