[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment: As Figure 1-6 shown, the present utility model provides a novel trailer axle structure, which includes a first vehicle axle body 1. One end of the first vehicle axle body 1 is provided with a second vehicle axle body 11. A first rotating member 2 is fixedly provided at one end of the first vehicle axle body 1 close to the second vehicle axle body 11. A second rotating member 21 is provided at one end of the first rotating member 2. A rotating rod 22 is rotatably inserted through the first rotating member 2 and the second rotating member 21. A first adjusting member 3 is fixedly provided at one end of the second vehicle axle body 11 close to the first vehicle axle body 1. A second adjusting member 31 is provided at one end of the first adjusting member 3. An adjusting rod 32 is rotatably inserted through the first adjusting member 3 and the second adjusting member 31.

[0020] On the outer wall of one side of the second adjusting member 31 close to the second rotating member 21, a mounting block 51 is fixedly provided. A mounting groove 5 is formed at one end of the second rotating member 21 close to the second adjusting member 31. The mounting groove 5 and the mounting block 51 are used in cooperation. A clamping groove 52 is formed in the mounting block 51. A spring 53 is provided in the second rotating member 21. One end of the spring 53 close to the mounting groove 5 is fixedly provided with a moving plate 54. The other end of the spring 53 away from the moving plate 54 is fixedly installed on the inner wall of the second rotating member 21. A clamping block 55 is fixedly provided at one end of the moving plate 54 away from the spring 53. The clamping groove 52 and the clamping block 55 are used in cooperation.

[0021] Fixing grooves 41 are formed at the four corners of one end of the second rotating member 21 close to the second adjusting member 31. Fixing blocks 4 are fixedly provided at the four corners of the outer wall of one side of the second adjusting member 31 close to the second rotating member 21. First threaded grooves 42 are formed in the fixing blocks 4. Second threaded grooves 43 are symmetrically distributed on the two outer walls of the second rotating member 21. The second threaded grooves 43 communicate with the corresponding fixing grooves 41 respectively. Bolts 44 are provided in the second threaded grooves 43.

[0022] A driving rod 56 is fixedly provided at one end of the moving plate 54 away from the clamping block 55. One end of the driving rod 56 away from the moving plate 54 slidably penetrates through one side wall of the second rotating member 21 and is located outside.

[0023] Symmetrically distributed first bearings 210 are sleeved on the outside of the rotating rod 22. The first bearings 210 are fixedly arranged inside the first rotating member 2; by providing the first bearings 210, it is achieved that the rotating rod 22 can stably rotate with the first rotating member 2, avoiding the situation of jamming between the rotating rod 22 and the first rotating member 2.

[0024] A symmetrically distributed second bearing 220 is sleeved outside the rotating rod 22, and the second bearing 220 is fixedly arranged inside the second rotating member 21; by providing the second bearing 220, it is possible to achieve stable rotation between the rotating rod 22 and the second rotating member 21, and prevent the situation of jamming between the rotating rod 22 and the second rotating member 21.

[0025] A symmetrically distributed third bearing 310 is sleeved outside the adjusting rod 32, and the third bearing 310 is fixedly arranged inside the first adjusting member 3; by providing the third bearing 310, it is possible to achieve stable rotation between the adjusting rod 32 and the first adjusting member 3, and prevent the situation of jamming between the adjusting rod 32 and the first adjusting member 3.

[0026] A symmetrically distributed fourth bearing 320 is sleeved outside the adjusting rod 32, and the fourth bearing 320 is fixedly arranged inside the second adjusting member 31; by providing the fourth bearing 320, it is possible to achieve stable rotation between the adjusting rod 32 and the second adjusting member 31, and prevent the situation of jamming between the adjusting rod 32 and the second adjusting member 31.

[0027] Working principle: First, when the trailer travels on a low-lying road surface, at this time, under the action of the first vehicle axis body 1 and the second vehicle axis body 11, the first rotating member 2 and the second rotating member 21 rotate around the rotating rod 22, preventing the wheels at the mutually remote ends of the first vehicle axis body 1 and the second vehicle axis body 11 from being suspended. When the trailer needs to turn, under the action of the first vehicle axis body 1 and the second vehicle axis body 11, the first adjusting member 3 and the second adjusting member 31 rotate around the adjusting rod 32, so that the first vehicle axis body 1 and the second vehicle axis body 11 can easily pass through a narrow turning area;

[0028] Subsequently, when it is necessary to fix between the first vehicle axis body 1 and the second vehicle axis body 11, the driving rod 56 is moved to drive the moving plate 54 to move. During the movement of the moving plate 54, the spring 53 is compressed and deformed. The moving plate 54 drives the block 55 to move. When the block 55 completely leaves the installation groove 5, the installation block 51 is inserted into the installation groove 5, and the fixing block 4 is inserted into the fixing groove 41. When the installation block 51 completely enters the installation groove 5, the fixing block 4 completely enters the fixing groove 41. At this time, the moving force on the driving rod 56 is removed, and then the spring 53 resets. Under the action of the restoring elastic force of the spring 53, the moving plate 54 drives the block 55 to move. When the block 55 completely enters the card slot 52, the pre-installation between the first vehicle axis body 1 and the second vehicle axis body 11 is completed. Subsequently, the bolt 44 is screwed into the first thread groove 42 and the second thread groove 43 to complete the installation and fixation between the first vehicle axis body 1 and the second vehicle axis body 11.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
