DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0026] See Figure 1 and Figure 2 As shown, a quick-install rectangular tube trampoline frame includes a frame 2 composed of several rectangular tubes 1 and a support sleeve structure 3 disposed on the outer wall of the frame. In actual use, one end of the rectangular tube is integrally formed with an insertion protrusion 4, and the other end is provided with an insertion cavity 5. In actual use, the cross-sectional shape and area of ​​the insertion protrusion match the internal shape and area of ​​the insertion cavity. This prevents shaking or shifting after installation. During assembly, adjacent rectangular tubes are connected, and the insertion protrusion of one rectangular tube is inserted into the insertion cavity of another rectangular tube for retention. Furthermore, in this embodiment, the support sleeve structure 3 includes a support tube body 31, a U-shaped notch clamp 32, and mounting bolts 33. During assembly, the U-shaped notch clamp is fixed to the top of the support tube body. The connection between adjacent rectangular tubes is inserted into the U-shaped notch clamp and secured by mounting bolts passing through the U-shaped notch clamp, the insertion cavity, and the insertion protrusion. The width and height of the U-shaped notch clamp match the rectangular tubes. The above structure makes the overall structure have good versatility and compatibility. The U-shaped notch clamp is used in conjunction with the mounting bolts for connection and positioning, which can also improve the convenience and stability of installation and prevent it from swinging or shaking.

[0027] In this embodiment, a bottom plate 6 is fixed to the bottom surface of the support tube. This can meet the installation requirements of a low-support trampoline, and the assembly process is simple and efficient, improving the convenience and stability of installation. In addition, the support tube can be replaced with the inverted M-shaped structure in Example 2 to meet the installation requirements of a high-support trampoline, improving its versatility.

[0028] In actual use, a protective net support tube 7, an arc-shaped clamp 8, and a positioning bolt 9 are also provided. During installation, the arc-shaped clamp is attached to the outer side of the U-shaped notch clamp and fixed with the mounting bolts. The lower portion of the protective net support tube is inserted into the arc-shaped clamp and is clamped and positioned by the arc-shaped clamp and the outer wall of the U-shaped notch clamp. The bottom end of the protective net support tube is attached to the outer wall of the support tube body and fixed with the positioning bolts. This structure ensures the smooth and reliable installation of the protective net support tube, while also improving the convenience of installation.

[0029] The utility model has positive effects: the structure of the utility model is reasonable, the adjacent rectangular tubes are connected and limited by the insertion protrusions and the insertion cavity, and are clamped into the U-shaped notch clamp and fixed by the installation bolts, which is not only convenient for disassembly and assembly, but also can ensure the stability and reliability of installation, and the support sleeve structure is also conducive to improving its versatility, which can meet the installation requirements of support tube bodies of different heights, and at the same time can also improve the stability of installation, and has strong practicality;

[0030] At the same time, it can also quickly realize the installation and positioning connection operations of the protective net support pipe, thereby improving practicality. Example 2

[0031] See Figure 3 and Figure 4 As shown, this embodiment is essentially the same as Example 1, except that the support tube is an inverted M-shaped structure, and the U-shaped notch clamps are fixed to the top ends of the vertical rods at both ends of the inverted M-shaped structure. In this embodiment, the inverted M-shaped structure is used to achieve a high-support trampoline, which is conducive to improving installation convenience. Example 3

[0032] See Figure 5 and Figure 6 As shown, this embodiment is basically the same as the first embodiment, except that it is installed in a pit and used as a flat trampoline. When in use, this embodiment needs to dig and shape the ground according to the corresponding shape to ensure the flatness of the bed surface. When dug, it can form two steps, one above the other. The bottom edge of the frame is located on the upper step, as shown in point A in the figure, and the support tube is located on the lower step, as shown in point B in the figure. This can prevent the soil on the upper step from loosening and falling. The gap between the two support tubes can also prevent soil from flowing into the pit, thereby improving the versatility of the trampoline.

[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
