[0025] See also Figure 1-4 A quickly detachable bottom shell wheel comprises a bottom shell 1 and two quick-release wheels 2, the two quick-release wheels 2 are respectively arranged on the symmetrical sides of the bottom shell 1, and the bottom shell 1 is detachably connected to two connecting plates 3, and the ends of the two connecting plates 3 that are away from each other can be detachably connected to connecting tubes 4, and the two connecting tubes 4 respectively pass through the symmetrical sides of the bottom shell 1, and the two quick-release wheels 2 are rotatably connected to the insert tubes 5, and the two insert tubes 5 are respectively inserted into the two connecting tubes 4, and the two insert tubes 5 are slidably connected to the telescopic rods 6, and the two insert tubes 5 are fixedly connected to the limited A positioning piece 7 is provided, and the two telescopic rods 6 are respectively slidably connected to the two limiting pieces 7. The two telescopic rods 6 are both sleeved with springs 8, and the two springs 8 correspond to the two limiting pieces 7 respectively. A bead groove group 9 is provided on the two telescopic rods 6, and a limiting bead group 10 is provided in the two bead groove groups 9. A bead hole group 11 is provided on the two insert tubes 5, and the two limiting bead groups 10 correspond to the two bead hole groups 11 respectively. The circumferential inner walls of the two insert tubes 5 are both provided with limiting grooves 12, and the two limiting bead groups 10 match the two limiting grooves 12 respectively.

[0026] In this embodiment, the two connecting plates 3 are fixedly installed in the bottom shell 1, and the two connecting tubes 4 are fixedly installed on both sides of the bottom shell 1 through the two connecting plates 3. When assembling the two quick-release wheels 2 and the bottom shell 1 of the lifting mechanical equipment, by pressing the two telescopic rods 6, the two telescopic rods 6 slide in the two limiting plates 7 of the two inserting tubes 5 respectively, and the two springs 8 are squeezed, and then the two inserting tubes 5 are respectively inserted into the two connecting tubes 4, so that the two limiting bead groups 10 are retracted into the two bead groove groups 9 through the two bead hole groups 11. When the two inserting tubes 5 are inserted into the two connecting tubes 4, the two bead hole groups 11 correspond to the two limiting grooves 12 respectively. At this time, the two telescopic rods 6 are released, and under the elastic force of the two springs 8 Use the two telescopic rods 6 to move and reset. The two telescopic rods 6 move to push the two limiting bead groups 10 outward from the two bead hole groups 11, so that the two limiting bead groups 10 are respectively clamped into the two limiting grooves 12. The two limiting bead groups 10 are located between the two bead hole groups 11 and the two limiting grooves 12, thereby realizing the restriction of the two inserting tubes 5 and completing the assembly of the two quick-release wheels 2 and the bottom shell 1 of the lifting mechanical equipment. When the two quick-release wheels 2 need to be removed, by pressing the telescopic rods 6, the two bead groove groups 9 correspond to the two limiting bead groups 10, and the two limiting bead groups 10 can be retracted into the two inserting tubes 5, so that the two inserting tubes 5 and the two connecting tubes 4 can be disassembled, thereby realizing the removal of the two quick-release wheels 2 from the lifting mechanical equipment.

[0027] Specifically, each telescopic rod 6 includes a sleeve rod portion 61, a pressing rod portion 62, and a limiting rod portion 63. The sleeve rod portion 61 is slidably connected to a limiting plate 7, and a spring 8 is sleeved on the circumferential surface of the sleeve rod portion 61. The pressing rod portion 62 is fixedly connected to one end of the sleeve rod portion 61, and the pressing rod portion 62 passes through one side of a quick-release wheel 2. The limiting rod portion 63 is fixedly connected to the other end of the sleeve rod portion 61, and a bead groove group 9 is opened on the circumferential surface of the limiting rod portion 63.

[0028] In this embodiment, by pressing the pressing rod 62, the sleeve rod 61 and the limiting rod 63 slide, and the pressing rod 62 cooperates with the limiting piece 7 to squeeze the spring 8, so that the limiting bead group 10 enters the bead groove group 9 and retracts. When the limiting bead group 10 corresponds to the limiting groove 12, the pressing rod 62 is released. Under the action of the elastic force of the spring 8, the pressing rod 62 drives the sleeve rod 61 and the limiting rod 63 to reset. The limiting rod 63 pushes the limiting bead group 10 out of the bead hole group 11 through the bead groove group 9. The circumferential surface of the limiting rod 63 supports the limiting bead group 10, limiting the retraction of the limiting bead group 10, so that the limiting bead group 10 is stuck between the bead hole group 11 and the limiting groove 12, completing the connection between the insert tube 5 and the connecting tube 4. By pressing the pressing rod 62 again, the bead groove group 9 is made to correspond to the limiting bead group 10, and the retraction restriction of the limiting bead group 10 is cancelled. When the insert tube 5 is pulled out to disassemble the quick release wheel 2, the limiting bead group 10 retracts into the bead groove group 9 through the bead hole group 11, completing the disassembly of the quick release wheel 2.

[0029] Specifically, bearings 13 are fixedly connected inside the two quick-release wheels 2 , and the two bearings 13 are fixedly connected to the circumferential surfaces of the two insertion tubes 5 .

[0030] In this embodiment, the two bearings 13 reduce the friction between the two quick-release wheels 2 and the two insertion tubes 5 , so that the quick-release wheels 2 can rotate smoothly on the insertion tubes 5 .

[0031] Specifically, bolts 14 are provided at the adjacent ends of the two connecting plates 3 , and the two bolts 14 respectively penetrate the two connecting plates 3 and are threadedly connected to the two connecting pipes 4 .

[0032] In this embodiment, the two connecting pipes 4 are mounted on the two connecting plates 3 by means of bolts 14 and are kept fixed, so as to facilitate the connection of the two inserting pipes 5 .

[0033] Working principle: When assembling the quick-release wheel 2 and the bottom shell 1 of the lifting mechanical equipment, the pressing rod 62 is pressed to make the sleeve rod 61 and the limiting rod 63 slide, and the pressing rod 62 cooperates with the limiting piece 7 to squeeze the spring 8, so that the limiting bead group 10 enters the bead groove group 9 and retracts. When the limiting bead group 10 corresponds to the limiting groove 12, the pressing rod 62 is released. Under the action of the elastic force of the spring 8, the pressing rod 62 drives the sleeve rod 61 and the limiting rod 63 to reset. The limiting rod 63 pushes the limiting bead group 10 out of the bead hole group 11 through the bead groove group 9, and the circumferential surface of the limiting rod 63 presses the limiting bead group 10 The limiting bead group 10 is supported and restricted to retract, so that the limiting bead group 10 is stuck between the bead hole group 11 and the limiting groove 12, completing the assembly between the quick-release wheel 2 and the bottom shell 1 of the lifting mechanical equipment. The two quick-release wheels 2 are assembled in the same way. When the quick-release wheel 2 needs to be removed, the pressing rod 62 is pressed again to make the bead groove group 9 correspond to the limiting bead group 10, and the retraction restriction of the limiting bead group 10 is cancelled. When the cannula 5 is pulled out to remove the quick-release wheel 2, the limiting bead group 10 retracts into the bead groove group 9 through the bead hole group 11, thereby realizing the removal of the quick-release wheel 2 from the lifting mechanical equipment. The two quick-release wheels 2 are removed in the same way.
