Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a quick-release universal wheel, including a bag 1. The bottom of the bag 1 has four mounting slots 16, and each of the four mounting slots 16 is equipped with a caster assembly. The caster assembly includes a mounting block 2. The outer surface of the mounting block 2 is slidably connected to the inner wall of the mounting slot 16. A universal wheel 3 is rotatably mounted on the bottom of the mounting block 2. The inside of the mounting block 2 has a groove 13. Two movable plates 14 are slidably connected inside the groove 13. A pressure spring 15 is fixedly connected between the two movable plates 14. Limit blocks 12 are fixedly connected to both sides of the two movable plates 14. Both sides of the mounting block 2 have through slots 4 and circular slots 7. The inner walls of the two through slots 4 are slidably connected with fixed rods 8. The opposite ends of the two fixed rods 8 are fixedly connected to the opposite ends of the two movable plates 14. The inner walls of the two circular slots 7 are slidably connected with pressure plates 5. The opposite ends of the two pressure plates 5 are fixedly connected to the opposite ends of the two movable plates 14.

[0026] Furthermore, a first limiting groove 11 is provided on both sides of the inner wall of the groove 13, and the inner walls of the two first limiting grooves 11 are slidably connected to the outer surfaces of the four limiting blocks 12.

[0027] Furthermore, both sides of the mounting block 2 are fixedly connected to limit plates 9, and multiple rollers 10 are rotatably installed on the opposite ends of the two limit plates 9.

[0028] Furthermore, a second limiting groove 17 is provided on both sides of the inner wall of the mounting groove 16, and the inner walls of the two second limiting grooves 17 are slidably connected to the inner walls of the two limiting plates 9.

[0029] Furthermore, circular slots 18 are provided on both sides of the inner wall of the mounting groove 16, and the inner walls of the two circular slots 18 are slidably connected to the outer surface of the corresponding fixing rod 8.

[0030] Furthermore, the top of the mounting block 2 is semi-circular, and a rubber pad 6 is fixedly connected to the top of the mounting block 2. The top of the rubber pad 6 contacts the bottom surface of the inner wall of the mounting groove 16.

[0031] Furthermore, there are four caster assemblies, and the four caster assemblies have the same structure. The internal structure of the four mounting slots 16 is the same, and the four caster assemblies are respectively set inside the four mounting slots 16.

[0032] Furthermore, when the user needs to replace or remove the caster wheel 3, the worker presses down on the two pressure plates 5. The two pressure plates 5 then move the two moving plates 14 relative to each other, causing the two moving plates 14 to compress the pressure spring 15. The two moving plates 14 then move the two fixed rods 8 relative to each other, causing the two fixed rods 8 to disengage from the interior of the two corresponding circular slots 18. This releases the fixing force on the mounting block 2 inside the mounting groove 16. The mounting block 2 is then slid down out of the mounting groove 16, allowing the mounting block 2 to drive the caster wheel 3 for replacement.

[0033] Furthermore, by setting the limiting block 12, when the moving plate 14 is moving, the movement of the moving plate 14 can be limited, thereby making the movement of the two moving plates 14 very stable.

[0034] Furthermore, by setting multiple rollers 10, the multiple rollers 10 are in contact with the inner wall of the second limiting groove 17. When the mounting block 2 slides down, the two limiting plates 9 will drive the multiple rollers 10 to rotate, so that the mounting block 2 can slide down and be disassembled more smoothly and conveniently, thus facilitating the disassembly and use of the mounting block 2.

[0035] Furthermore, when the mounting block 2 drives the caster 3 for assembly, the two pressure plates 5 are pressed against each other, and then the two pressure plates 5 drive the two moving plates 14 to move the two fixed rods 8 relative to each other. Then the two fixed rods 8 will temporarily retract into the two circular slots 18. Then the limiting plates 9 on both sides of the mounting block 2 are aligned with the two second limiting grooves 17. Then the two limiting plates 9 will slide into the two second limiting grooves 17. At the same time, multiple rollers 10 will contact the inner wall of the corresponding second limiting groove 17. At the same time, the mounting block 2 will also slide into the mounting groove 16. Then, when the two fixed rods 8 contact the corresponding circular slots 18 respectively, the two fixed rods 8 will enter the two circular slots 18 respectively, thereby fixing the mounting block 2 and thus completing the installation of the caster 3.

[0036] Furthermore, the two fixing rods 8 and the circular slot 18 enable the mounting block 2 to be quickly fixed inside the mounting slot 16, thereby allowing the caster wheel 3 to be quickly installed and removed. In conjunction with the roller 10, the sliding speed of the mounting block 2 during installation and removal is increased, making the installation and removal process of the caster wheel 3 simple and quick, thus facilitating the workers to install and remove it.

[0037] Furthermore, by setting the rubber pad 6, when the mounting block 2 slides up and is installed inside the mounting groove 16, the top of the mounting block 2 can be prevented from directly contacting the top surface of the inner wall of the mounting groove 16, thereby preventing contact and noise.
