[0046] The pool 1 includes a pool bottom 11 and a pool wall 12 sealed to the outer periphery of the pool bottom 11. Both the pool bottom 11 and the pool wall 12 are made of flexible, impermeable material. Depending on the needs, the sealing connection can be made by first processing the pool bottom and the pool wall and then sealing them together, or by integral molding, thereby defining a water storage cavity in the pool 1. The top of the pool wall 12 is provided with several circumferentially spaced through sleeves 13. For example, the top of the pool wall 12 is provided with several upwardly extending portions arranged at intervals. These upwardly extending portions are then folded back and fixed to the pool wall to form through sleeves 13 with horizontally arranged inner holes. The bottom surface of the pool bottom 11 is fixed with several circumferentially spaced pull straps 14. The fixing is done by welding, bonding, or fusion. The pull straps 14 extend outside the pool 1 and are located below the position formed by the interval between two adjacent through sleeves 13.

[0047] The ring frame 2 includes several side tubes 21, which pass horizontally through the inner hole of the sleeve 13. A connector 22 is installed between each pair of adjacent side tubes 21, and the several side tubes 21 are connected into a ring structure through the connector 22. The several sleeves 13 and the several side tubes 21 correspond one-to-one, and the two ends of each side tube 21 extend out of the two ends of the sleeve 13 respectively. The connector 22 is located in the gap formed by two adjacent sleeves 13 and directly above the pull strap 14 for easy assembly. The connector 22 has two horizontal insertion holes with the opening facing outward and one vertical insertion hole with the opening facing downward. The two horizontal insertion holes are arranged back to back, and the ends of two adjacent side tubes 21 are respectively inserted into the two horizontal insertion holes for easy assembly and disassembly and high support strength. In this embodiment, a connector 22 is installed between each pair of adjacent side tubes 21. However, if necessary, the connector 22 may not be provided. Instead, the first end of each side tube 21 forms a horizontal insertion end, and the second end forms a horizontal insertion hole. The horizontal insertion end of one side tube of two adjacent side tubes is inserted into the horizontal insertion hole of the other side tube to connect several side tubes 21 into a ring structure. The second end also has a vertical insertion hole with the opening facing downward for the upper end of the foot tube to be inserted. The specific structure is as follows: the second end of the side tube 21 is bent downward at 90 degrees, and the port after the second end is bent forms a vertical insertion hole. The opening at the bend forms a horizontal insertion hole.
