[0028] The outside of each rotatory bearing plate 3 is provided with a connecting mechanism for installing roller 6, the connecting mechanism includes mounting groove 7, connecting guide hole 8 and fixed insertion rod 9, mounting groove 7 is set in the outside of rotatory bearing plate 3, connecting guide hole 8 is set in the outside of rotatory bearing plate 3, connecting guide hole 8 extends to the inside of mounting groove 7, fixed insertion rod 9 is slidably connected in the inside of connecting guide hole 8, the outside of each roller 6 is provided with positioning hole 10, and the roller 6 is rotatably connected in the inside of mounting groove 7, and the fixed insertion rod 9 is slidably connected in the inside of the positioning hole 10.
[0029] The outer part of each rotating bearing plate 3 is provided with a limiting spring 11 for limiting the movement of the fixed insertion rod 9. The outer part of each rotating bearing plate 3 is provided with two limiting springs 11. The limiting spring 11 is fixedly installed on the outer part of the fixed insertion rod 9. The outer part of each rotating bearing plate 3 is provided with a spring accommodating groove 12 for placing the limiting spring 11. The limiting spring 11 is fixedly connected in the inner part of the spring accommodating groove 12. The inner part of each spring accommodating groove 12 is fixedly installed with a limiting guide shaft 13. The limiting spring 11 is movably connected to the outer part of the limiting guide shaft 13. The outer part of each fixed insertion rod 9 is provided with a guide hole 14 for the movement of the fixed insertion rod 9. The fixed insertion rod 9 is slidably connected to the outer part of the limiting guide shaft 13 through the guide hole 14.
[0030] The outer part of each rotating bearing plate 3 is provided with an active hole 15 for the movement of the threaded rod 4. The threaded rod 4 is movably connected in the inner part of the active hole 15. The outer part of each threaded rod 4 is fixedly installed with a limiting ring 16 for limiting. The limiting ring 16 is movably connected in the inner part of the active hole 15.
[0031] The bearing shaft 2 provides a rotating fulcrum for the rotating bearing plate 3, so that the rotating bearing plate 3 can rotate flexibly relative to the body 1, thereby adjusting the position of the roller 6 to adapt to different working scenes and ground conditions.
[0032] The threaded rod 4 cooperates with the positioning threaded hole 5 on the body 1 to lock the position of the rotating bearing plate 3. When the threaded rod 4 is screwed into the positioning threaded hole 5, the rotation of the rotating bearing plate 3 can be limited to ensure the stability of the roller 6 during work. When it is necessary to adjust the position of the roller 6, the threaded rod 4 is loosened, and the rotating bearing plate 3 can rotate freely.
[0033] The roller 6 is used for moving on the ground.
[0034] The mounting groove 7 provides a mounting space for the roller 6, so that the roller 6 can be stably placed on the rotating bearing plate 3. The connecting guide hole 8 provides a sliding channel for the fixed insertion rod 9, so that the fixed insertion rod 9 can move therein to cooperate with the positioning hole 10 on the roller 6, thereby realizing the quick installation and fixation of the roller 6 and preventing the roller 6 from accidentally falling off during work.
[0035] The limiting spring 11 is installed on the outer part of the fixed insertion rod 9. The elastic force of the limiting spring 11 is to push the fixed insertion rod 9 to insert into the positioning hole 10 of the roller 6, thereby realizing the automatic locking of the roller 6.
[0036] The spring accommodating groove 12 is used for accommodating the limiting spring 11 to provide an installation position for the limiting spring 11.
[0037] The limiting guide shaft 13 is installed inside the spring accommodating groove 12 and cooperates with the guide hole 14 on the fixed insertion rod 9 to further guide and limit the movement of the fixed insertion rod 9, prevent the fixed insertion rod 9 from deviating or disengaging from the connecting guide hole 8 during the movement, and ensure that the fixed insertion rod 9 is accurately connected with the positioning hole 10 of the roller 6. The guide hole 14 is formed on the fixed insertion rod 9, so that the fixed insertion rod 9 can slide on the limiting guide shaft 13 through the guide hole 14, which ensures the stable movement of the fixed insertion rod 9 and reduces the friction between the fixed insertion rod 9 and the limiting guide shaft 13;
[0038] The movable hole 15 is formed on the rotating bearing plate 3 to provide a movable space for the threaded rod 4, so that the threaded rod 4 can rotate freely in the rotating bearing plate 3. The limiting ring 16 is fixed outside the threaded rod 4 and located in the movable hole 15. The limiting ring 16 limits the axial movement range of the threaded rod 4 and prevents the threaded rod 4 from being disengaged from the movable hole 15 during the rotation, thereby preventing the threaded rod 4 from being lost.
[0039] Working principle:
[0040] Firstly, the fixed insertion rod 9 is pulled to move away from the spring accommodating groove 12, at this time the limiting spring 11 is stretched, and the roller 6 is placed into the installation groove 7 at this time. Then the fixed insertion rod 9 is released and moved into the positioning hole 10 under the action of the limiting spring 11, and the roller 6 is installed.
[0041] Secondly, when the roller 6 is used, the threaded rod 4 is disengaged from the positioning threaded hole 5, the rotating bearing plate 3 is rotated to make the roller 6 contact with the ground, the threaded rod 4 is rotated to connect with another positioning threaded hole 5, thereby fixing the position of the roller 6, so that the roller 6 can stably support the device and roll on the ground to realize the movement of the device. When the roller 6 is not needed, the threaded rod 4 is disengaged from the positioning threaded hole 5 again, the roller 6 is rotated to reset, the threaded rod 4 is rotated to connect with the positioning threaded hole 5 to fix the roller 6, so as to perform other work or avoid unnecessary damage to the roller 6.
[0042] Finally, it should be pointed out that: obviously, the above embodiments are only examples for clearly illustrating the utility model and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
