[0029] Please see Figure 1-3 A universal caster bracket includes a mounting plate 1, a bearing 2 fixedly connected to the bottom of the mounting plate 1, a rotating shaft 3 fixedly inserted into the inner ring of the bearing 2, and a wheel frame 5 connected to the bottom of the rotating shaft 3; the outer surface of the rotating shaft 3 is provided with a plurality of locking holes 4 equidistantly arranged in a circle, and a locking component 6 fixedly connected to the bottom of the mounting plate 1, the output end of the locking component 6 being movably inserted into the interior of the locking holes 4.

[0030] The locking assembly 6 includes a support plate 601, the top of which is fixedly connected to the bottom of the mounting plate 1. A rod 602 is movably inserted into the middle of the support plate 601, with one end of the rod 602 movably inserted into the locking hole 4. By providing a rotating shaft 3 with multiple locking holes 4 at the bottom of the mounting plate 1 and equipping it with the locking assembly 6 with the rod 602, when the equipment needs to be fixed, the rod 602 is inserted into the corresponding locking hole 4 on the rotating shaft 3, thereby restricting the rotation of the rotating shaft 3 and preventing the universal casters from rotating. This ensures the stability of the equipment in a static state, effectively solving the problem that existing universal casters lack a reliable locking mechanism and that the equipment is prone to accidental movement due to external forces. This avoids equipment damage and reduces the risk of safety hazards to surrounding personnel.

[0031] In this embodiment, there are two support plates 601, which are symmetrically and fixedly connected to the bottom of the mounting plate 1. A limiting plate 603 is fixedly sleeved on the outer surface of the insertion rod 602, and the limiting plate 603 is located between the two support plates 601. The other end of the insertion rod 602 is bent downward. The limiting plate 603 can prevent the insertion rod 602 from moving excessively or falling off, ensuring the reliability of the locking assembly 6. At the same time, the downward bending of the insertion rod 602 facilitates manual insertion and removal operations by the operator, improving ease of use.

[0032] The bottom of the rotating shaft 3 passes through the through hole on the wheel frame 5 and extends into the interior of the wheel frame 5. A fixing nut 8 is threaded onto the bottom of the rotating shaft 3. This arrangement can fix the wheel frame 5 onto the rotating shaft 3.

[0033] A base 7 is movably fitted on the outer surface of the rotating shaft 3. The base 7 is located between the fixing nut 8 and the wheel frame 5. The base 7 can evenly distribute the pressure applied by the fixing nut 8 to the surface of the wheel frame 5, reducing local stress concentration.

[0034] Both sides of the wheel frame 5 are provided with through wheel axle holes 9. When assembling the swivel casters, simply pass the wheel axle through the wheel axle holes 9 on both sides of the wheel frame 5 and the center hole of the wheel, and then use appropriate parts to fix the two ends of the wheel axle to complete the wheel installation. The operation is simple and quick. When the wheel is worn or damaged and needs to be replaced, the wheel axle can be easily removed, the old wheel can be removed and the new wheel can be installed.

[0035] The mounting plate 1 has through mounting slots 10 at the four corners of its top, which makes it easy to install the caster bracket onto various equipment and improves its versatility.

[0036] Bearing 2 is a deep groove ball bearing. The outer ring of bearing 2 is fixedly connected to the bottom of mounting plate 1, and the inner ring of bearing 2 is fixed with the rotating shaft 3 by interference fit. This allows the caster to rotate freely 360 degrees in the horizontal direction, improving the flexibility of equipment movement.

[0037] The diameter of the locking hole 4 is matched with the diameter of the insertion rod 602. When it is necessary to lock the swivel caster, the insertion rod 602 is inserted into the locking hole 4. The matching hole diameter ensures that the insertion rod 602 and the locking hole 4 fit tightly and there will be no loosening or shaking.
