Detailed Description

In order to make the utility model discloses a utility model purpose, technical scheme and technological effect are more clear and are understood, and it is right to combine specific embodiment below the utility model discloses do further explanation. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, a trampoline of current popularity generally includes a bouncing pad 10 and a frame 20, and a plurality of flexible rods 30, the top ends 31 of the flexible rods 30 being mounted at the periphery or bottom of the bouncing pad 10, and the bottom ends of the flexible rods 30 being mounted on the frame 20, thereby erecting the bouncing pad 10 above the frame 20. Under the pressure of the bouncing pad 10, the flexible rod 30 will typically bend through an arc, thereby tensioning the bouncing pad 10. The user can bounce, play and perform on the bouncing pad 10. The flexible rod 30 is preferably an aircraft aluminum rod, a fiberglass rod or a carbon fiber rod.

The bouncing pad 10 is preferably circular, but may be any other shape, such as square, regular pentagon, regular hexagon, oval, etc. The frame 20 is a round shape formed by connecting a plurality of arc steel pipes 21 end to end, and the joints of the adjacent arc steel pipes 21 are respectively provided with a first plug-in barrel and a first plug-in connector which are matched with each other; the first plug connector is inserted into the first plug cylinder and fixedly connected with the first plug cylinder through a pin.

The frame 20 is preferably placed on the support legs 40 and may also be placed on the ground.

The flexible rods 30 are typically required to have some buckling resistance in order to support the bouncer pad and the user. Particularly, when the flexible rod 30 is installed, the bottom of the flexible rod 30 is usually fixed on the frame 20, and then the top of the flexible rod 30 is deflected from the natural straightened state to the center direction of the bouncing pad 10, so that the flexible rod 30 supports and tensions the bouncing pad 10 to satisfy the elasticity required for bouncing.

In the prior art, the bending rigidity of the flexible rods of the trampoline is generally less than 3000N/m, which requires that the upper ends of the flexible rods deflect from the natural straightened state not connected with the edge of the bounce pad to the center of the bounce pad by 300 mm and 450mm, so as to support the bounce pad and enable the elasticity of the bounce pad to meet the requirements of the trampoline. The bending stiffness of the prior art flexible rod 30 is too low, resulting in poor elastic recovery and easy bending. After a period of use of the trampoline, the flexible rods 30 cannot return to their original positions, so that the trampoline 10 is no longer under tension, and the structure is relaxed and the elasticity is reduced. In addition, when the bending rigidity of the flexible rod is less than 3000N/m, the maximum size of the bouncing pad can only be 13FT, and if not, the elasticity of the bouncing pad cannot meet the requirement.

As a result of intensive studies, the applicant has found that the above-mentioned drawbacks can be overcome by increasing the flexural rigidity of the flexible rod. The application the flexible rod be bending stiffness for 3000N/m ~ 10000N/m's straight-bar, install the bottom of flexible rod on the frame, its top deflects 10-200mm to the center of spring pad from the nature state of straightening, thereby makes the flexible rod is crooked, and installs the periphery or the bottom of spring pad, with support and tensioning spring pad. When the bending rigidity of the flexible rod is 3000N/m-10000N/m, the elastic restoring force of the flexible rod is increased, and the flexible rod is not easy to fatigue and deform. In addition, although the bending stiffness of the flexible beam is increased, the distance of deflection toward the center of the trampoline is reduced, making installation easier.

The material of the common flexible rod in the market at present is glass fiber rod or carbon fiber. The glass fiber rod has good corrosion resistance, insulating property, heat insulation, high strength and the like. However, the glass fiber rod has the defects of high hardness, poor bending resistance, poor abrasion resistance, poor flexibility and the like in combination with the inherent brittleness. The glass fiber rod is easy to crack after being repeatedly used for a long time and used in a low-temperature state, loses the original elasticity, and sometimes is also broken to cause the damage of the trampoline, so that the potential safety hazard exists. In addition, according to 2017, 10, 27, glass fiber is listed in a category 3 carcinogen list published by the international cancer research institution of the world health organization, and is unsafe material.

Preferably, the flexible rod 30 is made of aluminum alloy. The aluminum alloy is light in weight, the surface of the aluminum alloy is oxidized, the wind resistance and the pressure resistance of the aluminum alloy are higher than those of a glass fiber rod, and the aluminum alloy has the advantages of good strength, toughness, fatigue resistance, good plasticity, difficulty in fracture and the like. Even if the bearing pressure exceeds the upper limit, the aviation aluminum rod cannot be broken, but the bending degree is increased, the trampoline cannot be damaged, and the safety of the trampoline is improved.

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

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

Or the bottom end of the flexible rod 30 may be directly inserted into the sleeve 26, and then both are inserted into the pair of upper insertion holes 24 and the pair of lower insertion holes 25, so that the installation is simple and convenient.

It should be understood that the lower end of the flexible rod 30 is fixed in the inserted position in the frame 20 after the lower end of the flexible rod 30 and the sleeve 26 are inserted into the lower insertion hole 25. When the top ends of all the flexible rods 30 are installed around the bounce mat 10, the installation positions of the top ends of the flexible rods 30 are unchanged, and the tension and the elasticity of the bounce mat 10 are constant.

Preferably, the upper insertion hole 24 is provided as an elliptical hole having both ends, denoted as a end and B end, located inside and outside the upper side of the frame, respectively. The elastic member 27 is inserted into the a end or the B end of the oval hole, thereby adjusting the position of the flexible rod 30 in the frame 20, and thus the tightness of the bounce mat and the elasticity thereof. Specifically, when the bottom end of the flexible rod 30 and the sleeve 26 pass through the upper insertion hole 24, they are inserted into the lower insertion hole 25. When the elastic member 27 is inserted into the position a, i.e., the position where the upper insertion hole 24 is close to the inside of the upper side of the frame 20, the flexible rod 30 and the sleeve 26 are pressed to be located at the position B. At this time, the tension of the flexible rod 30 on the bounce mat 10 is large, and the elasticity of the bounce mat 30 is high. When the elastic member 27 is inserted into the B position, i.e. the position where the upper insertion hole 24 is close to the outer side of the frame 20, the flexible rod 30 and the first sleeve 26 are pressed to the a position, the tension to the bounce mat 10 is small, and the elasticity of the bounce mat 10 is low.

Referring to fig. 6, the side of the elastic element 27 clinging to the first sleeve 26 is an inner side surface 271, the side clinging to the hole wall is an outer side surface 272, the inner side surface 271 and the outer side surface 272 are both arc surfaces, a clamping block 273 is arranged at the joint of the two arc surfaces, and the clamping block 273 and the limiting groove 28 are matched in shape and can be clamped with each other.

Preferably, an upper protrusion 274 extends from the intersection of the latch 273 and the outer side surface 272. The bottom of the outer side surface 272 of the elastic member 27 extends to form a lower convex portion 275. When the elastic member 27 is inserted into the upper insertion hole 24, the upper protrusion 274 and the lower protrusion 275 respectively hold the periphery of the hole wall of the upper insertion hole 24 from the upper and lower directions of the upper insertion hole 24, thereby preventing the elastic member from falling off from the upper insertion hole 24.
