[0021] In order to enable the personnel in the technical field to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in conjunction with the embodiments.

[0023] Embodiment 1

[0024] See Figures 1 - 4 , this embodiment provides an adjustable anti-offset wheel mechanism, including a disc body 1, which serves as the main part of the entire anti-offset wheel mechanism, providing structural support and a fixed foundation. A connecting plate 2 is fixedly connected to the lower end of the disc body 1. An inner side of the connecting plate 2 is fixedly connected with a mounting plate 3. Mounting holes 4 are formed on the surface of the mounting plate 3. A rectangular frame 5 is fixed between the connecting plates 2. An anti-offset slider 6 is arranged on a side surface of the rectangular frame 5, and its main function is to prevent the wheel or related components from offsetting during operation. A translation and flipping mechanism is arranged inside the rectangular frame 5. An activity port 9 is formed at the bottom of the rectangular frame 5;

[0025] The translation and flipping mechanism includes a moving block 71 arranged inside the rectangular frame 5. Two fixed blocks 72 are fixedly connected to the lower end of the moving block 71. A rotating shaft 73 is rotatably connected between the two fixed blocks 72. One end of the rotating shaft 73 penetrates through one of the fixed blocks 72 and is fixedly connected with a connecting block 74. A sliding shaft 75 is fixedly connected to the other side of the connecting block 74. A guide groove 76 is formed on an inner wall of the rectangular frame 5, and the guide groove 76 provides a guiding path for the sliding shaft 75. A C-shaped block 711 is fixedly sleeved on an outer wall of the rotating shaft 73.

[0026] The translation and flipping mechanism further includes two through holes 77, which are opened on the sides of the rectangular frame 5 and the connecting plate 2. A positioning hole is opened on the side of the moving block 71. A positioning pin 78 is slidably connected inside the through hole 77, and a limiting sleeve 79 is movably sleeved on the outer wall of the positioning pin 78.

[0027] A slide rail 710 is fixedly connected to the upper end inside the rectangular frame 5, and the moving block 71 is slidably connected to the outer wall of the slide rail 710.

[0028] When the device is in specific use, when it is necessary to change the position of the anti-deviation slider 6, first remove the limiting sleeve 79 from the outside of the positioning pin 78, then make the positioning pin 78 leave the inside of the positioning hole on the side of the moving block 71, and then push the moving block 71 to slide on the outer wall of the slide rail 710. Then the fixing block 72 and the rotating shaft 73 on its surface will move accordingly. Then the connecting block 74 at one end of the rotating shaft 73 will drive the sliding shaft 75 to move together. At the same time, one end of the sliding shaft 75 will be inside the guiding groove 76. When the sliding shaft 75 moves to the inclined part of the guiding groove 76, it will drive the rotating shaft 73 to rotate through the connecting block 74. Then the U-shaped block 711 on the outer wall of the rotating shaft 73 will rotate downward. Then when the sliding shaft 75 moves to the horizontal section in the middle of the guiding groove 76, it will make the U-shaped block 711 move parallel for a certain distance. When the sliding shaft 75 moves to the inclined end on the other side of the guiding groove 76, it will make the U-shaped block 711 rotate inward and finally move to be parallel to the moving block 71. During this process, the U-shaped block 711 will drive the anti-deviation slider 6 to move through the fixing mechanism, thereby realizing the external installation and internal installation of the anti-deviation slider 6.

[0029] Embodiment 2

[0030] See Figures 1 - 4 , on the basis of Embodiment 1, a fixing mechanism is arranged inside the U-shaped block 711. The fixing mechanism includes an installation block 81, which is located inside the U-shaped block 711. A threaded rod 82 is rotatably connected to the inner wall of the U-shaped block 711. A moving block 83 is threadedly connected to the outer wall of the threaded rod 82. A positioning rod 84 is fixedly connected to the outer wall of the moving block 83. A positioning hole is opened on the side of the installation block 81. One end of the threaded rod 82 penetrates through the U-shaped block 711 and is fixedly connected to a rotating block 85. The outer wall of the installation block 81 is fixedly connected to the anti-deviation slider 6.

[0031] A limiting rod 86 is fixedly connected to the inner wall of the U-shaped block 711, and the moving block 83 is slidably connected to the outer wall of the limiting rod 86. The limiting rod 86 limits the moving range of the moving block 83.

[0032] A guiding block 87 is fixedly connected to the inner wall of the U-shaped block 711. A limiting groove 88 is opened in the middle of the installation block 81. The guiding block 87 and the limiting groove 88 ensure that the installation block 81 can be smoothly guided during replacement or adjustment, avoiding jamming phenomena.

[0033] When the above-mentioned device is in specific use and it is necessary to replace the anti-deviation slider 6, first, turn the rotating block 85 to drive the threaded rod 82 to rotate. Then, the movable block 83 threadedly connected to its outer wall will move along with the restriction of the limiting rod 86, thereby driving the positioning rod 84 to move. When the positioning rod 84 leaves the positioning hole inside the side of the mounting block 81, the mounting block 81 can be taken out from the inside of the U-shaped block 711, so that the anti-deviation slider 6 can be replaced. Conversely, a new anti-deviation slider 6 can be installed. In addition, the mounting block 81 can be guided by the limiting groove 88 in the middle of the mounting block 81 and the guiding block 87 on the inner wall of the U-shaped block 711.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
