The cross-section of the first slide groove 4 is rectangular, and the cross-section of the second slide groove 5 is circular. The first slide groove 4 and the second slide groove 5 are respectively adapted to the rectangular slider 9 and the ball 8. The rectangular slider 9 is slidably connected to the equipment body 1 through the first slide groove 4, and the ball 8 is slidably connected to the equipment body 1 through the second slide groove 5. The bolt 3 is rotated to drive the lifting plate 2 to move downward, and the movement of the lifting plate 2 drives the first plug rod 7 to move downward at the same time and engage with the groove 13. Four sets of caster seat bodies 6 can be installed at the same time. The bolt 3 is rotated in the opposite direction to drive the first plug rod 7 to move upward at the same time and disengage from the groove 13, pushing the caster seat body 6 to move along the front side or rear side close to the direction of another caster seat body 6 on the same side until the caster seat body 6 is separated from the equipment body 1. Two sets of caster seat bodies 6 can be disassembled at the same time, and the disassembly and assembly efficiency is high.

[0027] like Figure 1-Figure 4 As shown, a position adjustment component is arranged inside the device body 1, and the position adjustment component consists of a vertical slot 10, a connecting rod 11, a second plug rod 12 and a hole slot 14. Two vertical slots 10 are arranged inside the device body 1 close to the first plug rod 7. A connecting rod 11 is hinged on the outside of the first plug rod 7. The connecting rod 11 is arranged inside the vertical slot 10. The other end of the connecting rod 11 is hinged on the second plug rod 12. A hole slot 14 adapted to the second plug rod 12 is connected between the second slide groove 5 and the vertical slot 10. The second plug rod 12 is slidably connected to the device body 1 through the hole slot 14. The second plug rod 12 is connected to the groove 13. Correspondingly, the second plug rod 12 is slidably connected to the ball 8 through the groove 13, and the position adjustment component can install the caster seat body 6 on the left or right side of the equipment body 1, which is convenient for the equipment body 1 to be flipped ninety degrees for movement or transportation, thereby improving the applicability of the device. A T-shaped slider 15 is fixedly provided on the bottom surface of the second plug rod 12, and a T-shaped groove 16 adapted to the T-shaped slider 15 is provided on the bottom surface of the vertical groove 10. The T-shaped slider 15 is slidably connected to the equipment body 1 through the T-shaped groove 16. The T-shaped slider 15 cooperates with the T-shaped groove 16 to guide the second plug rod 12 of the position adjustment component.

[0028] Specifically, rotating the bolt 3 drives the first plug rod 7 to move upward at the same time, so that the first plug rod 7 disengages from the groove 13. The first plug rod 7 moves upward and drives the connecting rod 11 to rotate at the same time. The rotation of the connecting rod 11 drives the second plug rod 12 to move in the direction close to the first plug rod 7 until the second plug rod 12 completely disengages from the second slide groove 5. The ball 8 and the rectangular slider 9 are moved along the first slide groove 4 and the second slide groove 5. The movement of the ball 8 and the rectangular slider 9 drives the caster seat body 6 to move, and all four groups of caster seat bodies 6 are moved to the left or right side of the equipment body 1, and the groove 13 of the ball 8 is aligned with the second plug rod 12, and then the bolt 3 is rotated in the opposite direction to drive the second plug rod 12 to engage with the groove 13, so that the caster seat body 6 is installed on the left or right side of the equipment body 1.

[0029] Specific working principle:

[0030] When the device needs to disassemble or install the caster seat body 6, the caster seat body 6 is installed along the top of the equipment body 1 and the lifting plate 2 and moved to the bottom of the equipment body 1, the groove 13 of the spherical body 8 is aligned with the first plug rod 7, and the bolt 3 is rotated to drive the lifting plate 2 to move downward. The movement of the lifting plate 2 drives the first plug rod 7 to move downward at the same time and engage with the groove 13. Four groups of caster seat bodies 6 can be installed at the same time, and the bolt 3 is rotated in the opposite direction to drive the first plug rod 7 to move upward at the same time and disengage from the groove 13, pushing the caster seat body 6 to move along the front or rear side in the direction close to another caster seat body 6 on the same side until the caster seat body 6 is separated from the equipment body 1. Two groups of caster seat bodies 6 can be disassembled at the same time, and the disassembly and assembly efficiency is high.

[0031] Rotating the bolt 3 drives the first plug rod 7 to move upward at the same time, so that the first plug rod 7 disengages from the groove 13. The first plug rod 7 moves upward and drives the connecting rod 11 to rotate at the same time. The rotation of the connecting rod 11 drives the second plug rod 12 to move in the direction close to the first plug rod 7 until the second plug rod 12 completely disengages from the second slide groove 5, and moves the ball 8 and the rectangular slider 9 along the first slide groove 4 and the second slide groove 5. The movement of the ball 8 and the rectangular slider 9 drives the caster seat body 6 to move, and all four sets of caster seat bodies 6 are moved to the left or right side of the equipment body 1, and the groove 13 of the ball 8 is aligned with the second plug rod 12, and then the bolt 3 is rotated in the opposite direction to drive the second plug rod 12 to engage with the groove 13. The caster seat body 6 can be installed on the left or right side of the equipment body 1, which is convenient for the equipment body 1 to be flipped ninety degrees for movement or transportation, thereby improving the applicability of the device.
