A second plug-in hole 44 is provided in the center of both end surfaces of the protective tube 36, and a limiting card slot 45 is provided at the bottom of both end surfaces of the limiting cross bar 35. Positioning plug rods 46 are slidably inserted into the two ends of the limiting cross bar 35, and a tension spring 47 is sleeved on the outer surface of one end of the positioning plug rod 46. A right-angle frame 39 is slidably connected to the two ends of the protective tube 36. A protective sleeve 38 is sleeved on the outer surface of the right-angle frame 39, and a hinge 42 is rotatably connected to one end of the right-angle frame 39.

[0031] The first maintenance device 1 is aligned and plugged with the plug-in plate 5 and the plug-in column 4 at the bottom and the plug-in groove 13 and the connecting hole 15 on the side of the second maintenance device 2 respectively, which can enhance the stability of the bottom connection between the first maintenance device 1 and the second maintenance device 2. The top two end surfaces of the internal limiting arc wall 12 of the second maintenance device 2 are provided with arc-shaped plug holes, and one end of the arc-shaped connecting rod 7 is slidably plugged with the top side of the internal limiting arc wall 12 of the second maintenance device 2 through the arc-shaped plug hole, so as to connect the top of the limiting arc wall 12 inside the first maintenance device 1 and the second maintenance device 2.

[0032] The inner diameter of the limiting arc wall 12 is five centimeters larger than the operating size of the turntable 18, which can prevent 230 from contacting the inner surface of the limiting arc wall 12 when rotating and deflecting. The bottom surface of the counterweight base 16 is fixedly connected to the inner bottom surface of the limiting arc wall 12 through the clamping groove 6, which can ensure the bottom stability of the disco rotating device 3. The supporting device 27 is slidably clamped with the annular slide 25 through the first clamping block 29 and the second clamping block 30 at both ends, thereby facilitating the adjustment of the position of the protective seat 19 inside the rotating base 23.

[0033] A positioning hole is provided on the side of the backrest 32. Before the tourist sits in the protective seat 19, a fastening screw can be used to penetrate the positioning hole and fasten it to the inner surface of the rotating base 23, so that the protective seat 19 is positioned inside the rotating base 23. The limiting cross bar 35 is connected to the outer surface of the limiting frame 31 through the limiting card grooves 45 at the bottom of both ends. One end of the positioning plug rod 46 penetrates and is plugged into the inside of the limiting card groove 45, so that the limiting cross bar 35 can be limited to the outer surface of the limiting frame 31. The right-angle frame 39 is slidably plugged into the first plug-in hole 33 and the second plug-in hole 44 respectively through the plug-in rods 40 at both ends, so as to facilitate the adjustment of the spacing between the two sets of right-angle frames 39. The positioning tooth block 43 is slidably connected to the top of the backrest 32 and the protective tube 36 through the limit frame 34. The top of the backrest 32 and the protective tube 36 is provided with tooth grooves, which can facilitate the engagement of the positioning tooth block 43 with the tooth grooves, thereby positioning the plug-in rod 40 in the first plug-in hole 33 and the second plug-in hole 44.

[0034] Working principle: When experiencing the disco turntable, tourists first enter the interior of the first maintenance device 1 through the entrance and exit ladder 10, then enter the interior of the rotating base 23 by opening the gate 21, and then sit on the upper surface of the cushion 26. When the rotating base 23 rotates, they can grab the inner surface of the rotating base 23. At the same time, some tourists can sit inside the protective seat 19 to prevent themselves from losing a firm grip, so that the protective seat 19 can protect the tourists and prevent them from flying out as the rotating base 23 rotates. When using the protective seat 19, the protective seat 19 can be adjusted so that the protective seat 19 can be adapted to protect tourists of different body shapes. When using the protective seat 19, first pull the ends of the limit cross bar 35 The positioning rods 46 of the tourist are slid close to each other until one end of the positioning rod 46 is disengaged from the inside of the limiting slot 45, and at the same time, the limiting cross bar 35 is pulled as a whole to drive the right-angle frame 39 to synchronously turn upward with the hinge 42 as the axis. At the same time, the limiting slots 45 at both ends of the limiting cross bar 35 will be separated from the outer surface of the limiting frame 31. Then the tourist sits on the inner center of the supporting device 27, and at the same time, the upper body passes through the inner center of the protective frame 28, so that the two sets of protective sleeves 38 are connected to the tourist's shoulders. Then, the distance between the two sets of right-angle frames 39 is adjusted according to the tourist's body shape. First, the second positioning screws 41 at both ends of the right-angle frames 39 are turned forward. Since the positioning tooth block 43 is restricted from rotating by the limiting frame 34, the positioning tooth block 43 will rise, and then the two sets of right-angle frames 39 are pulled together. The second positioning screw 41 is then rotated in the opposite direction to allow the positioning tooth block 43 to drop and engage with the tooth grooves on the top of the backrest 32 and the protective tube 36, thereby positioning the two sets of right-angle frames 39 after sliding. The protective frame 28 is pulled to rotate, drop and flip until the limiting slot 45 engages with the limiting frame 31, and the external force on the outer surface of the positioning rod 46 is removed. The positioning rod 46 will reset and slide under the elastic force of the tension spring 47, thereby locking the limiting frame 31 inside the limiting slot 45, and completing the adaptation and protection adjustment of the protective seat 19. Then the disco rotating device 3 can be started to operate. At the same time, the rotating base 23 will rotate and bump. When the tourist cannot hold on firmly, he can grab the grip ring 22 or the handle 24 at the center of the upper surface of the rotating base 23 to position himself and avoid rolling back and forth inside the rotating base 23. When the tourist leaves the rotating base 23 in time, the convex pads 9 on the inner surfaces of the first maintenance device 1 and the second maintenance device 2 can play a buffering and protective role for the tourist to avoid the tourist from colliding with metal and getting injured. By arranging a protective seat 19 on the disco turntable, some tourists can be prevented from leaving the turntable. At the same time, the protective seat 19 can be adapted and adjusted according to the body shape of the tourist. In addition, the convex pads 9 are arranged inside the first maintenance device 1 and the second maintenance device 2 to protect the tourist.Avoid causing harm to tourists.
