[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-Figure 4 The utility model provides an embodiment: a caster that is easy to disassemble, including a shell 1, the shell 1 is fixedly connected to a fixed shaft 2, the fixed shaft 2 is rotatably connected to a ratchet 3, the ratchet 3 is fixedly connected to a gear 4, the gear 4 is fixedly connected to a fixed ring 5, a volute spring 6 is provided between the fixed ring 5 and the fixed shaft 2, the shell 1 is hinged with a pawl 7, the pawl 7 is meshed with the ratchet 3, a spring 8 is provided between the pawl 7 and the shell 1, the gear 4 is meshed with a rack 9, and the rack 9 is fixedly connected to a clamping seat 10.

[0029] The pawl 7 is fixedly connected with a pull rope 11, and the pull rope 11 is fixedly connected with a pull ring 12. The clamping seat 10 is fixedly connected with a spring 2 13, and the spring 2 13 is fixedly connected with a connecting seat 15. A damper 14 is provided between the clamping seat 10 and the connecting seat 15. The connecting seat 15 is rotatably connected with a rotating frame 16, and the rotating frame 16 is rotatably connected with a wheel body 17. The shell 1 is provided with an insertion groove 18, and the insertion groove 18 is slidably connected with the rack 9. The shell 1 is fixedly connected with a mounting plate 19, and the mounting plate 19 is provided with a mounting hole 20. The pawl 7 of the ratchet wheel 3 can be unlocked by pulling the pull ring 12, thereby driving the gear 4 to rotate under the action of the spiral spring 6, and pushing out the rack 9, thereby realizing the rapid disassembly of the caster, so as to facilitate daily maintenance and replacement, and bring greater convenience to the user. The spring 2 13 and the damper 14 arranged between the clamping seat 10 and the connecting seat 15 can realize shock absorption during the travel of the caster, thereby improving the operating stability of the equipment and reducing noise.

[0030] Working principle: when disassembly is required, the user only needs to pull the pull ring 12, and the pull ring 12 drives the pawl 7 to rotate through the pull rope 11, and the pawl 7 is disengaged from the ratchet 3 and is no longer locked, so that under the elastic force of the spiral spring 6, the fixed ring 5 drives the gear 4 to rotate around the fixed axis 2, and the rotation of the gear 4 drives the rack 9 to move, thereby ejecting the rack 9 from the insertion slot 18, and the quick disassembly of the caster is completed. When installing a new caster, it is only necessary to insert the rack 9 from the insertion slot 18, the rack 9 drives the gear 4 to rotate, and the gear 4 drives the ratchet 3 to rotate. The ratchet 3 cannot be reversed under the restriction of the pawl 7, thereby completing the stable installation of the rack 9. The housing 1 can be installed on the equipment through the mounting hole 20 on the mounting plate 19. During the travel of the caster, the spring 2 13 and the damper 14 isolate the vibration of the wheel body 17, thereby avoiding the influence of the vibration on the upper equipment.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
