[0021] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0022] Embodiment 1

[0023] Refer to Figures 1 to 7As shown, a luggage caster convenient for assembly and disassembly according to the present embodiment comprises a wheel support 1 and a wheel frame 2, a wheel 3 is arranged on the wheel frame 2, a plug hole 4 is provided on the wheel support 1, a plug shaft 5 is inserted in the plug hole 4 and rotates therein, one end of the plug shaft 5 is connected to the wheel frame 2, a side of the plug shaft 5 is provided with an annular groove 6, a mounting groove 7 extending along the radial direction of the plug hole is provided on the wheel support 1, and a groove bottom of the mounting groove 7 is provided with a groove extending along its length direction and penetrating the wheel The first shift hole 8 of the support, the inner shift block 9 is slidably connected in the mounting groove 7, the outer shift block 10 connected to the inner shift block is slidably connected in the first shift hole 8, the mounting groove 7 is provided with an elastic member (not shown) with one end against the inner shift block and the other end against the mounting groove wall, the elastic member is a compression spring, the inner shift block 9 is provided with a limit plate 12 for follow-up, the limit plate 12 is provided with a limit hole 13 for the plug-in shaft 5 to penetrate, and the limit plate 12 in a natural state is stuck in the annular groove 6.

[0024] In this embodiment, when the wheel frame 2 and the wheel support 1 are in the connected state, the plug-in shaft 5 is inserted into the plug-in hole 4. Due to the elastic force generated by the elastic member, the limit plate 12 is away from the plug-in shaft 5. At this time, the limit hole 13 is not concentric with the plug-in hole 4, and the limit plate 12 is stuck in the annular groove 6, and the plug-in shaft 5 cannot be pulled out from the plug-in hole 4. If the wheel frame 2 and the wheel support 1 need to be separated, the outer shifting block 10 can be pushed toward the plug-in shaft 5, driving the inner shifting block 9 connected thereto to squeeze the elastic member until the limit plate 12 moves with it, gradually disengaging the limit plate 12 stuck in the annular groove 6, until the limit hole 13 is concentric with the plug-in hole 4, and the plug-in shaft 5 can be pulled out from the plug-in hole 4.

[0025] Example 2

[0026] See also Figures 1 to 7 As shown, the present embodiment involves a luggage caster that is easy to disassemble and assemble. On the basis of Embodiment 1, it is further configured that a locking groove 14 is provided on the wheel support 1 and is perpendicular to the length direction of the mounting groove 7. The locking groove 14 is communicated with the mounting groove 7. A second shifting hole 15 extending along the length direction and passing through the wheel support is provided at the bottom of the locking groove 14. An inner locking block 16 is slidably connected in the locking groove 14 and a part of the locking block can also be slid into the mounting groove. An outer locking block 17 connected to the inner locking block is slidably connected in the second shifting hole 15. A limiting groove 18 is provided on the side of the inner shift block 9 for inserting the inner locking block 16.

[0027] Furthermore, a shift protrusion 19 is provided on the side surface of the inner locking block 16, and a first shift groove 20 and a second shift groove 21 matching the shift protrusion are provided on the groove wall of the locking groove 14.

[0028] In this embodiment, when the plug-in shaft 5 cannot be pulled out from the plug-in hole 4, the side sliding outer locking block 17 can drive the inner locking block 16 connected to it to be inserted into the limit groove 18, until the inner shift block 9 cannot be moved in the installation groove 7, causing the limit plate 12 to be "locked".

[0029] The gear protrusion 19 cooperates with the first gear groove 20 and the second gear groove 21 to lock the position of the inner locking block 16 after the position adjustment is completed.
