[0016] like Figures 1-5 The diagram shows a quick-release flexible wheel for rail transit, comprising a cover plate 1, a mounting plate 5, and a quick-release assembly installed between the cover plate 1 and the mounting plate 5. The mounting plate 5 is annular and fixedly installed on the outer wall of the wheel axle. The quick-release assembly includes a rotating rod 6, a fixing plate 9, and a fitting block 10. Multiple quick-release assemblies are arranged in a circular array on the outer wall of the cover plate 1. The cover plate 1 is annular and fitted to one side of the mounting plate 5. The outer wall of the cover plate 1 has multiple through grooves, and the outer wall of the mounting plate 5 has multiple threaded holes. The threaded holes and through grooves... The slots are connected, and the number of multiple through slots and threaded holes corresponds to the number of quick-release components. The outer wall of the fitting block 10 is threaded and the thread is installed inside the threaded hole of the mounting plate 5. The fixing plate 9 is installed at the opening of the threaded hole and is fixedly connected to the top of the fitting block 10. The top of the fitting block 10 is provided with a groove. The outer wall of the fixing plate 9 is provided with a through slot 13. The bottom outer wall of the rotating rod 6 is fixedly installed with a fixing rod 14. The rotating rod 6 passes through the through slot and the slot 13 of the fixing plate 9. The fixing rod 14 is engaged inside the groove of the fitting block 10.

[0017] The slot 13 consists of a circular slot and a long slot connected together. The shape of the long slot corresponds to that of the fixed rod 14. A fitting tube 11 is fitted into the opening of the through slot of the cover plate 1. A spring 8 is installed inside the fitting tube 11. A pressure block 7 is fitted into the opening of the fitting tube 11. One end of the rotating rod 6 is fixedly connected to the pressure block 7. A handle 4 is fixedly installed on the outer wall of the pressure block 7 away from the rotating rod 6. The handle 4 abuts against the outer wall of the opening of the fitting tube 11. The spring 8 is sleeved on the outside of the rotating rod 6. A rubber ring 12 is fitted onto the outer wall of the rotating rod 6. The rubber ring 12 is embedded in the inner wall of the through slot. An arc-shaped groove is opened at the top of the handle 4. A pressure ring 2 is provided on the outer wall of the handle 4. The outer wall of the pressure ring 2 is embedded in the arc-shaped groove of the handle 4. Multiple bolts 3 are installed on the outer wall of the pressure ring 2. The multiple bolts 3 pass through the pressure ring 2 to fix the cover plate 1 and the mounting plate 5 together.

[0018] When the cover plate 1 needs to be disassembled, the bolt 3 can be rotated, the bolt 3 is taken out, the pressing ring 2 is taken out from the arc-shaped groove of the handle 4, the pressing ring 2 is used for pressing the handle 4, then the handle 4 is rotated, the fixing rod 14 at the bottom of the rotating rod 6 is rotated out of the groove of the embedded block 10, the spring 8 lifts the pressing block 7 upwards, so that the fixing rod 14 passes through the slot 13 of the fixing plate 9, the operator can take out the pressing block 7, the rotating rod 6 and the rubber ring 12 together with the embedded pipe 11 through the handle 4, the outer diameter of the rubber ring 12 is the same as that of the embedded pipe 11, and the rubber ring 12 and the embedded pipe 11 are embedded in the through groove of the cover plate 1, so that the rubber ring 12 can be taken out together with the embedded pipe 11, at this time, the cover plate 1 can be separated from the mounting plate 5. The rubber ring 12 is used for increasing the friction force with the inner wall of the through groove and increasing the stability of the rotating rod 6 installed in the through groove.
