Description

[Technical field]

[0001] The utility model relates to the field of sports equipment, in particular to a trampoline frame with handrail tubes. [Background technology]

[0002] Trampolines are usually divided into large trampolines and small trampolines. Large trampolines usually refer to trampolines with a diameter greater than 1.5 meters, and small trampolines usually refer to trampolines with a diameter less than 1.5 meters. Since small trampolines have a smaller diameter, users are prone to bump into the surrounding guardrail pipes when bouncing. In order to solve this problem, the more commonly used method is to add handrail pipes so that users can hold the handrail pipes during the bouncing process to avoid such collisions, thereby greatly improving the safety of trampoline use.

[0003] Please refer to the prior art (patent number 202221457482.X), which discloses a trampoline frame structure with handrails in the prior art.

Since the bolts are exposed to the outside, there is a risk of bumping for the user. If a protective cover is added to the bolt, it affects the appearance and increases the production cost. 2. This structure is cumbersome to install; 3. It is easy to loosen over time.

[0004] Therefore, it is necessary to provide a trampoline frame with handrail pipes that solves the above-mentioned technical problems. [Utility Model Content]

The leg tubes 1 are arranged in an inverted U shape, and the leg tubes 1 include a vertical support portion 10 and a transverse connecting portion 11. The vertical support portions 10 of each two adjacent leg tubes 1 are flattened to include the vertical guardrail tubes 2 therein, and then the three are fixed by a fixing member 4, so that the trampoline frame has a higher structural strength. Each vertical guardrail tube 2 is connected to its two adjacent transverse guardrail tubes 3 by a three-way connector 5, and the three-way connector 5 is a plastic part. A handrail tube 6 is provided above the transverse guardrail tube 3. In this embodiment, the handrail tube 6 is provided in an inverted U shape. A connecting tube 7 is provided between the handrail tube 6 and the three-way connector 5. In this embodiment, the upper end of the connecting tube 7 is sleeved on the outer side of the lower end of the handrail tube 6. A nut 8 is welded to the outer side of the upper end of the connecting tube 7. A handwheel bolt 9 is installed in the nut 8.
