Detailed ways

In order to make the purpose of the utility model, the technical solution and the technical effect of the utility model clearer and clearer, the utility model will be further explained below in conjunction with the specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present utility model and are not used to limit the present utility model.

1, the current popular trampoline usually includes a bounce mat 10 and a frame 20, and multiple flexible rods 30, the top end 31 of the flexible rod 30 is installed on the periphery or bottom of the bounce mat 10, the bottom of the flexible rod 30 The end is installed on the frame 20 so that the bounce mat 10 is erected above the frame 20. Under the pressure of the bounce mat 10, the flexible rod 30 usually bends in a certain arc, thereby tensioning the bounce mat 10. The user can bounce, play and perform on the bounce mat 10. The flexible rod 30 is preferably an aviation aluminum rod, a glass fiber rod or a carbon fiber rod.

The bounce pad 10 is preferably circular, but can also be any other shape, such as a square, a regular pentagon, a regular hexagon, an ellipse, and the like. The frame 20 is a circular shape formed by connecting several sections of arc-shaped steel pipes 21 end to end, and the joints of adjacent arc-shaped steel pipes 21 are respectively provided with a first plug barrel and a first plug connector; The plug connector is inserted into the first plug barrel, and the two are fixedly connected by a pin.

The frame 20 is preferably placed on the supporting legs 40, and can also be placed on the ground.

In order to support the bounce pad and the user, the flexible rod 30 generally needs to have a certain bending resistance. Especially when the flexible rod 30 is installed, the bottom of the flexible rod 30 is usually fixed on the frame 20 first, and then the top of the flexible rod 30 is deflected from the natural straight state toward the center of the bounce pad 10, The flexible rod 30 is made to support and tension the bounce pad 10 to meet the elasticity required for bounce.

In the prior art, the bending stiffness of the flexible rod of the trampoline is generally less than 3000N/m, which requires the upper end of the flexible rod to be deflected 300-450mm from the natural straight state not connected to the edge of the bounce mat to the center of the bounce mat. Support the bounce mat and make the elasticity of the bounce mat meet the requirements of a trampoline. The flexural rigidity of the flexible rod 30 in the prior art is too low, resulting in poor elastic recovery ability and easy bending. After using the trampoline for a period of time, the flexible rod 30 cannot return to the original position, so that the bounce mat 10 no longer maintains a tensioned state, the structure is loosened, and the elasticity decreases. In addition, when the bending stiffness of the flexible rod is less than 3000N/m, the maximum size of the bounce mat can only be 13FT, otherwise, the elasticity of the bounce mat cannot meet the requirements.

For this reason, after in-depth research, the applicant found that increasing the bending stiffness of the flexible rod can overcome the above-mentioned defects. The flexible rod described in this application is a straight rod with a bending rigidity of 3000N/m～10000N/m. The bottom end of the flexible rod is installed on the frame, and the top end of the flexible rod is deflected from the natural straight state to the center of the bounce pad 10-200mm, so that the flexible rod is bent and installed on the periphery or bottom of the bounce pad to support and tension the bounce pad. When the flexible rod has a bending stiffness of 3000 N/m to 10000 N/m, the elastic restoring force of the flexible rod is increased, and it is not easy to be fatigued and deformed. In addition, although the bending stiffness of the flexible rod is increased, the distance to deflect to the center of the bounce pad is reduced, making the installation easier.

Common flexible rods on the market are made of glass fiber rods or carbon fiber. The glass fiber rod has good corrosion resistance, insulation performance, heat insulation and high strength. However, the glass fiber rod has high hardness, combined with its inherent brittleness, the material has defects such as intolerance to bending, poor wear resistance, and poor flexibility. Fiberglass rods are prone to cracking after long-term repeated use and use at low temperatures, lose their original elasticity, and sometimes break because of this, causing damage to the trampoline and posing safety risks. In addition, according to the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization on October 27, 2017, glass fiber is listed in the list of three carcinogens, which is an unsafe material.

Preferably, the material of the flexible rod 30 in the present application is an aluminum alloy rod. The aluminum alloy material is light, the surface is oxidized, and the wind resistance and compression resistance are stronger than the glass fiber rod. At the same time, it has good strength, toughness, fatigue resistance and plasticity, and it is not easy to break. Even if the bearing pressure exceeds the upper limit, the aviation aluminum pole will not break, but will increase the curvature, will not cause damage to the trampoline, and improve the safety of the trampoline.

Preferably, the diameter of the flexible rod is 0.5-3.0 cm.

Preferably, the length of the flexible rod is 0.3-1.5m.
