[0029] As attached Figure 1 To Attachment Figure 6 As shown, a swing mechanism capable of realizing reciprocating motion is suitable as a driving device of a pendulum-type amusement device, which comprises a fixed shaft 1, a boom 2 movably arranged on the fixed shaft 1, and a telescopic device 3 capable of driving the boom 2 to swing or rotate relative to the fixed shaft 1, and the lower end of the boom 2 is used to install a cabin assembly. The telescopic device 3 is arranged on the boom 2, a fixed pulley assembly 41 is arranged on the fixed shaft 1, and a guide pulley 42 is arranged at the lower end of the boom 2. One end of the telescopic device 3 is fixedly connected to the fixed shaft 1 after passing through the fixed pulley assembly 41 through a first rope 43, and the other end of the telescopic device 3 is fixedly connected to the fixed shaft 1 after passing through the guide pulley 42 and the fixed pulley assembly 41 in turn through a second rope 44. Only one set of driving structure is needed to realize the reciprocating swinging motion of the pendulum-type amusement device, which has the advantages of simple structure, smooth motion without abnormal sound, and simple installation process.

[0030] In this embodiment, as shown in the attached Figure 2 As shown, the fixed shaft 1 includes a fixed rod 11, at least one rotating head 12 mounted on the fixed rod 11, and a slewing bearing 13, the slewing bearing 13 includes an inner ring and an outer ring, the inner ring of the slewing bearing 13 is fixedly connected to the fixed rod 11, the outer ring of the slewing bearing 13 is fixedly connected to the rotating head 12, and the lower end of the rotating head 12 is fixedly connected to the boom 2. The relative movement between the fixed shaft 1 and the boom 2 is achieved through the connection of the slewing bearing 13. In this embodiment, in order to make the movement smoother and the force more uniform, there are two rotating heads 12, and the two rotating heads 12 are respectively located at the two ends of the fixed rod 11, and the two rotating heads 12 are respectively connected to the fixed rod 11 through the slewing bearing 13.

[0031] In this embodiment, the telescopic device 3 includes a fixed component 31 fixedly connected to the boom 2 and a movable component 32 that can reciprocate relative to the fixed component 31, one end of the movable component 32 is connected to a first rope 43, and the other end of the movable component 32 is connected to a second rope 44; when the movable component 32 moves downward relative to the fixed component 31, the length of the first rope 43 wrapped around the fixed pulley assembly 41 becomes shorter and the length of the second rope 44 wrapped around the fixed pulley assembly 41 becomes longer, thereby causing the boom 2 to swing toward the side of the telescopic device 3; when the movable component 32 moves upward relative to the fixed component 31, the length of the first rope 43 wrapped around the fixed pulley assembly 41 becomes longer and the length of the second rope 44 wrapped around the fixed pulley assembly 41 becomes shorter, thereby causing the boom 2 to swing toward the side away from the telescopic device 3; the transmission of the swinging motion is achieved by traction of the first rope 43 and the second rope 44.

[0032] In this embodiment, there are two implementations of the fixed pulley assembly 41 . The first embodiment is: the fixed pulley assembly 41 includes a first fixed pulley and a second fixed pulley arranged on a fixed shaft, the upper end of the movable component 32 is connected to one end of a first rope 43, the other end of the first rope 43 is fixedly connected to the fixed shaft after passing around the first fixed pulley, the lower end of the movable component 32 is connected to one end of a second rope 44, the other end of the second rope 44 is fixedly connected to the fixed shaft after passing around the guide pulley 42 and the second fixed pulley in sequence, and the winding direction of the first rope 43 is opposite to the winding direction of the second rope 44; when the movable component 32 moves downward relative to the fixed component 31, the length of the first rope 43 wound around the first fixed pulley decreases and the length of the second rope 44 wound around the second fixed pulley increases, thereby causing the boom 2 to swing toward the side facing the telescopic device 3; when the movable component 32 moves upward relative to the fixed component 31, the length of the first rope 43 wound around the first fixed pulley increases and the length of the second rope 44 wound around the second fixed pulley decreases, thereby causing the boom 2 to swing toward the side away from the telescopic device 3.

[0033] The second embodiment is: the fixed pulley assembly 41 includes a third fixed pulley arranged on the fixed shaft, the third fixed pulley is provided with a first fixed slide groove and a second fixed slide groove, the upper end of the movable component 32 is connected to one end of the first rope 43, the other end of the first rope 43 is fixedly connected to the fixed shaft after passing through the first fixed slide groove, the lower end of the movable component 32 is connected to one end of the second rope 44, the other end of the second rope 44 is fixedly connected to the fixed shaft after passing through the guide pulley 42 and the second fixed slide groove in turn, the winding direction of the first rope 43 is consistent with the winding direction of the second rope 44 has an opposite winding direction; when the movable part 32 moves downward relative to the fixed part 31, the length of the first rope 43 wrapped around the first fixed slide groove becomes shorter and the length of the second rope 44 wrapped around the second fixed slide groove becomes longer, thereby causing the boom 2 to swing toward the side of the telescopic device 3; when the movable part 32 moves upward relative to the fixed part 31, the length of the first rope 43 wrapped around the first fixed slide groove becomes longer and the length of the second rope 44 wrapped around the second fixed slide groove becomes shorter, thereby causing the boom 2 to swing toward the side away from the telescopic device 3.

[0035] In this embodiment, if Figure 6 As shown, the telescopic device 3 is an oil cylinder or a gas cylinder. Specifically, the fixed component 31 is a cylinder barrel, and the movable component 32 is a cylinder rod that is inserted into the cylinder barrel and can reciprocate up and down relative to the cylinder barrel; the cylinder barrel is fixedly connected to the boom 2, the upper end of the cylinder rod is connected to one end of the first rope 43, and the upper and lower ends of the cylinder rod are connected to one end of the second rope 44. A pushing chamber 310 is provided in the cylinder barrel, and a pushing block 321 that can reciprocate in the pushing chamber 310 is provided in the middle of the cylinder rod. The pushing block 321 divides the pushing chamber 310 into a first chamber 311 and a second chamber 312. The pushing block 321 is sealed and connected to the wall of the pushing chamber 310.

In this embodiment, the telescopic device 3 is preferably an oil cylinder or a gas cylinder, which has a simpler structure.

[0036] In this embodiment, the cabin assembly can rotate relative to the boom 2 along the axis A, and the axis A is the center line of the boom 2, so that the cabin assembly of the pendulum-type amusement equipment can swing and rotate at the same time, thereby enhancing the tourists' play experience and making it more exciting and fun.
