This can lead to instability and shaking during display. Furthermore, the advertising machine is not easily disassembled, making it inconvenient for transportation. Therefore, improvements are needed. Utility Model Content

[0022] Please see Figure 1 , Figure 2A combined 3D holographic advertising machine includes a base 1, with multiple evenly distributed support seats 2 fixedly connected to the bottom of the base 1. A motor 3 is fixedly installed inside the base 1, and a rotating seat 4 is fixedly installed at the upper end of the output end of the motor 3. A square rod 5 is fixedly connected to the top of the rotating seat 4, and a turntable 6 is slidably sleeved on the outer side of the square rod 5. A square groove 11 is opened inside the turntable 6, and the square rod 5 is slidably connected inside the square groove 11. By designing the square groove 11, the turntable 6 can slide along the square rod 5, and the square rod 5 can drive the turntable 6 to rotate. The turntable 6 is rotatably connected to the base 1. A bracket 7 is fixedly installed on the top of the turntable 6 by bolts. A holographic display group 10 is set on the top of the bracket 7. A limit mechanism 8 is set on the rotating seat 4, and a combination mechanism 9 is set on the base 1.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The limiting mechanism 8 includes a slot 81. A slot 81 is formed inside the rotating seat 4. A ball 82 is movably fitted inside the slot 81. There are multiple slots 81, which are arranged in a ring and evenly distributed inside the rotating seat 4. By designing multiple slots 81, the ball 82 can roll into different positions within the slots 81. A limiting seat 83 is movably fitted outside the ball 82. The limiting seat 83 is fixedly connected to the base 1 and rotatably connected to the rotating seat 4. A slider 84 is movably sleeved on the outside of the slide 84, and a slide rod 85 is fixedly connected to the outside of the slider 84. Both the slider 84 and the slide rod 85 are slidably connected to the limiting seat 83. A first spring 86 is provided on the outside of the slide rod 85. One end of the first spring 86 is fixedly connected to the slider 84, and the other end of the first spring 86 is fixedly connected to the limiting seat 83. By designing the first spring 86, the force of the first spring 86 can be applied to the slider 84. By designing the limiting mechanism 8, the stationary rotating seat 4 can be limited.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The assembly mechanism 9 includes an annular groove 91. The turntable 6 has an annular groove 91 inside. A connecting block 92 is slidably connected inside the annular groove 91. The connecting block 92 is slidably connected to the base 1. A push rod 93 is fixedly connected to the top of the connecting block 92. The push rod 93 is slidably connected to the base 1. A guide rod 94 is slidably sleeved inside the connecting block 92. The guide rod 94 is fixedly connected to the base 1. A second spring 95 is provided on the outside of the guide rod 94. One end of the second spring 95 is fixedly connected to the connecting block 92, and the other end of the second spring 95 is fixedly connected to the base 1. By designing the second spring 95, the force of the second spring 95 can act on the connecting block 92. A magnetic block 96 is fixedly connected to the bottom of the connecting block 92. The magnetic block 96 is slidably connected to the base 1. A magnet 97 is fixedly connected inside the base 1. By designing the assembly mechanism 9, it is convenient to separate the turntable 6 from the base 1.

[0025] The specific implementation process of this utility model is as follows: In use, the holographic display group 10 can achieve the purpose of 3D holographic advertising. When the motor 3 is working, the output end of the motor 3 can drive the rotating seat 4 to rotate, the rotating seat 4 drives the square rod 5 to rotate, the square rod 5 will drive the turntable 6 to rotate, the turntable 6 will slide along the connecting block 92, and at the same time the turntable 6 will drive the bracket 7 and the holographic display group 10 to rotate, so as to realize the all-round display of 3D holographic advertising.

[0026] When the rotating seat 4 rotates, it also rotates along the limiting seat 83. The arc surface of the slot 81 inside the rotating seat 4 will squeeze and push the ball 82, causing the ball 82 to roll away from the rotating seat 4. The ball 82 will drive the slider 84 and the slide rod 85 to move horizontally. The slider 84 can squeeze and compress the first spring 86, which can separate the ball 82 from the slot 81. When the motor 3 stops working, the rotating seat 4 stops rotating. At this time, under the elastic action of the first spring 86, it will give the slider 84 a reverse thrust, which can push the ball 82 into the slot 81 in another position. At this time, the rotating seat 4 in the stationary state can be limited and locked, thereby limiting the structure of the turntable 6 and the holographic display group 10, which facilitates the fixed-point display of 3D holographic advertising and avoids the problem of instability during fixed-point display.

[0027] When it is necessary to disassemble the turntable 6, push the push rod 93 horizontally. The push rod 93 drives the connecting block 92 to move. The connecting block 92 will slide along the guide rod 94 and squeeze the second spring 95. At the same time, the connecting block 92 will drive the magnetic block 96 to move. When the magnetic block 96 is attracted to the magnet 97, the connecting block 92 will slide out from the inside of the turntable 6. Then the turntable 6 can be directly pulled out from the inside of the base 1. The advertising machine adopts a modular design, which is convenient for transportation and carrying after disassembly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
