DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] As Figures 1 to 3 shown, a connecting device for a tourist sightseeing small train in this embodiment includes a main body 1. A partition 2 is connected inside the main body 1. A threaded rod 3 is threadedly connected to the top end of the main body 1 on one side of the partition 2. The bottom end of the threaded rod 3 penetrates through the top end of the main body 1 and extends into the main body 1. The extended end of the threaded rod 3 is rotatably connected to a push block 4. A first insertion rod 6 is arranged inside the main body 1 on one side of the push block 4. A connecting block 8 is detachably installed on one side of the main body 1. One end of the first insertion rod 6 penetrates through the main body 1 and extends into the side wall of the connecting block 8 and into the connecting block 8. Slots 7 are provided on both the upper and lower surfaces of the extended end of the first insertion rod 6. Second springs 11 are connected to both the upper and lower ends inside the connecting block 8. One end of each second spring 11 is connected to a second insertion rod 12. One side of the second insertion rod 12 forms a sliding connection with the inner side wall of the connecting block 8 through a slider and a chute, and one side of the lower part of the second insertion rod 12 is set as an inclined surface. The inclined surface of the second insertion rod 12 extends into the slot 7. By rotating the threaded rod 3, the threaded rod 3 drives the push block 4 to move downward. During the downward movement of the push block 4, the push block 4 pushes the first insertion rod 6 to move into the connecting block 8, and the first insertion rod 6 continues to move through between the two second insertion rods 12. At this time, both second springs 11 are in a compressed state. When the second insertion rods 12 are located above the slots 7, during the rebound process of the two second springs 11, the inclined ends of the two second insertion rods 12 are respectively driven to move into the two slots 7, so that the first insertion rod 6 is fixedly inserted into the connecting block 8.

[0020] Specifically, a through hole 5 is provided on one side of the main body 1. The upper and lower surfaces of the first insertion rod 6 are in sliding connection with the inner wall of the through hole 5, which plays a role in supporting the first insertion rod 6 and makes the movement of the first insertion rod 6 more stable.

[0021] Further, one side wall of the inner cavity of the connecting block 8 is connected with a first connecting rod 9. One end of the first connecting rod 9 extends into the first inserting rod 6. A first spring 10 is sleeved outside the first connecting rod 9. One end of the first spring 10 is connected with the inner wall of the connecting block 8, and the other end of the first spring 10 is connected with the first inserting rod 6. When the thrust on the pushing block 4 disappears, the pushing block 4 moves into the main body 1 under the action of the resilience of the first spring 10, facilitating the disassembly of the locomotive head and the carriage. A kit 13 is sleeved on the side of the main body 1 away from the threaded rod 3. The kit 13 is connected with the front end of the carriage. Both the upper and lower parts inside the kit 13 are connected with fixing rods 14. One end of the fixing rod 14 penetrates through the main body 1 and extends into the main body 1 on the other side of the partition plate 2. The extended end of the fixing rod 14 is connected with a pressing block 15. When the kit 13 is impacted, the kit 13 drives the fixing rod 14 to move inside the main body 1, and the fixing rod 14 drives the pressing block 15 and the first permanent magnet 19 to move towards the second permanent magnet 20. Inside the main body 1 on the other side of the partition plate 2, there are two pressing plates 16. A third spring 21 is connected between the two pressing plates 16. A hydraulic damper is connected between the two pressing plates 16, and the third spring 21 is sleeved on the outer surface of the hydraulic damper. Rotating seats 17 are installed on the opposite surfaces of the pressing plate 16 and the pressing block 15. A second connecting rod 18 is rotatably connected between the two rotating seats 17. By squeezing the third spring 21 with the two pressing plates 16, the third spring 21 contracts to absorb the impact force.

[0022] Furthermore, a first permanent magnet 19 is connected to one side surface of the pressing block 15. A second permanent magnet 20 is connected to the other side surface of the partition plate 2 on the side of the first permanent magnet 19. There is a positive and negative pole difference. The first permanent magnet 19 and the second permanent magnet 20 repel each other with the same pole to absorb the impact force, and the repulsive force between the first permanent magnet 19 and the second permanent magnet 20 is not large, only applicable to the tourist sightseeing small train.

[0023] The usage method of this embodiment is as follows: When it is necessary to install the locomotive head and the carriage, align the main body 1 at the front end of the carriage with the connecting block 8 at the rear end of the locomotive head, and then rotate the threaded rod 3. The threaded rod 3 drives the push block 4 to move downward. During the downward movement of the push block 4, the first insertion rod 6 is pushed to move into the connecting block 8, and the first insertion rod 6 continues to move through between the two second insertion rods 12. At this time, the second springs 11 are all in a compressed state. When the second insertion rods 12 are located above the slots 7, during the rebound process of the two second springs 11, the inclined ends of the two second insertion rods 12 are respectively driven to move into the two slots 7, so that the inclined ends of the two second insertion rods 12 are inserted into the two slots 7 of the first insertion rod 6, making the first insertion rod 6 fixedly inserted into the connecting block 8, improving the connection stability between the locomotive head and the carriage. When the small train brakes, the rear carriage has a forward driving force, thus pushing the kit 13 forward, and further driving the fixing rod 14 to move inside the main body 1. The fixing rod 14 drives the pressing block 15 together with the first permanent magnet 19 to move towards the second permanent magnet 20. The impact force is absorbed by the mutual repulsion of the first permanent magnet 19 and the second permanent magnet 20. And the two pressing blocks 15 drive the two pressing plates 16 to move towards the third spring 21 respectively through the two second connecting rods 18. The two pressing plates 16 squeeze the third spring 21, and the third spring 21 contracts to absorb the impact force, playing a role in buffering and shock absorption for the carriage.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
