[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0038] Example 1

[0039] See also Figures 1 to 4The present embodiment provides a trampoline elastic rod mounting structure 100a, which is arranged on a trampoline 200. The trampoline has a mat 210 and a plurality of elastic rods 220, and the elastic rods 220 have a first top end 221. The trampoline elastic rod mounting structure 100a includes an extension 110 and a split buckle structure 120a. The extension 110 is fixedly connected to the periphery of the mat 210 or the bottom near the periphery. The extension 110 is detachably mounted on the first top end 221 through the split buckle structure 120a. The split buckle structure 120a and the extension 110 are connected to form a straight structure 150, and the straight structure 150 extends radially outwardly of the mat 210. The straight structure 150 has the function of preventing feet from bumping.

[0040] When the installation structure 100a of the trampoline elastic rod is installed, the extension piece 110 is detachably installed on the first top end 221 through the split buckle structure 120a, and the installation is completed by buckling, which has the advantages of convenient installation and easy operation.

[0041] The split buckle structure 120a of the trampoline elastic rod and the extension 110 are connected to form a straight structure 150. The elastic force between the mat and the elastic rod straightens and tightens the straight structure 150. The split buckle structure 120a is not easy to separate during use, and has a high safety factor.

[0042] The extension piece 110 is detachably mounted on the first top end 221 of the elastic rod 220 through the split buckle structure 120a, so that the first top end 221 of the elastic rod 220 is mounted at the periphery of the mat 210 or at the bottom close to the periphery. Since the split buckle structure 120a and the extension piece 110 are connected to form a straight structure 150, when the user bounces to the edge of the mat 210, it plays a role in preventing the user from bumping his feet, and the user experience is better and the safety factor is higher. In summary, the trampoline elastic rod 220 is detachably mounted from the mat 210 through the split buckle structure 120a, and has the advantages of convenient assembly and disassembly, simple operation, and effortless installation.

[0043] See also Figure 2 The split buckle structure 120a includes a hook member 130a and a hook hole member 140a, and the hook member 130a can be detachably hooked on the hook hole member 140a. The hook member 130a and the hook hole member 140a have the advantages of simple structure, easy processing, convenient installation and firm connection.

[0044] See also Figure 3The hook member 130a includes a flat plate portion 131 and a first U-shaped hook portion 132. The flat plate portion 131 serves to prevent foot bumping. The flat plate portion 131 has a connecting end 1311, a hooking end 1312, and a first bottom surface 1313. The hooking end 1312 is bent toward the first bottom surface 1313 to form the first U-shaped hook portion 132. The above design has the advantages of simple structure and easy processing. The first U-shaped hook portion 132 has a hook opening, and the hook opening faces the mat 210.

[0045] See also Figure 3 The connecting end 1311 is provided with a first connecting hole 1314, and the extension piece 110 is connected to the first connecting hole 1314. The extension piece 110 is a flexible belt, one end of which is fixedly connected to the mat 210, and the other end of which can movably pass through the hook 130a and be fixedly connected to the periphery of the mat 210 or the bottom near the periphery. Specifically, the other end of the flexible belt can movably pass through the first connecting hole 1314. The flexible belt can be a belt, a rubber belt or a soft plastic belt, preferably a woven belt made of the same material as the mat 210.

[0046] See also Figure 3 and Figure 4 The hook hole member 140a includes a tube body 141, a mounting head 142 and a first hook 143. The tube body 141 has an insertion hole 1411 and a second top end 1412, the mounting head 142 is arranged at the second top end 1412, the first hook 143 is arranged at the bottom of the mounting head 142, and the first hook 143 is used to hook the mesh of the trampoline protective net. A groove 145 is provided at the top of the mounting head 142, and the groove 145 has a bottom wall 1451 and two opposite side walls 1452a, 1452b. Specifically, a slope reinforcement part 1454a, 1454b is respectively provided at the connection between the two opposite side walls 1452a, 1452b and the bottom wall 1451. The slope reinforcement parts 1454a, 1454b are used to strengthen the strength of the structure. A column 1453 is fixedly disposed between two opposite side walls 1452 a and 1452 b of the groove 145 , and the bottom of the column 1453 and the bottom wall 1451 of the groove 145 form a first hook hole 147 a .

[0047] The mounting head 142 has the advantage of enhancing the structural strength, so that the mounting structure 100a of the trampoline elastic rod 220 meets the requirements of a large trampoline. During installation, the first U-shaped hook 132 and the mounting head 142 are pulled close together, the first U-shaped hook 132 extends into the first hook hole 147a and hooks the column 1453, and the elastic force generated by the elastic rod 220 makes the first U-shaped hook 132 tightly hooked on the column 1453, and the extension 110 is tightened and straightened. During disassembly, the mounting head 142 is further offset toward the mat 210 to separate the first U-shaped hook 132 from the column 1453, thereby disassembling the first U-shaped hook 132 and the mounting head 142.

[0049] The difference between this embodiment and embodiment 1 is: Figure 5 and Figure 6 The first U-shaped hook portion 132 has an outer side surface 1321, and a reinforcing rib 1322a, 1322b is respectively provided on both sides of the outer side surface 1321. The reinforcing ribs 1322a, 1322b play a role in enhancing strength. A thickened portion 1317 is provided at the connecting end 1311. Similarly, the thickened portion 1317 is used to strengthen the structural strength of the connecting end 1311. The connecting end 1311 is subjected to greater force, and the thickened portion 1317 prevents the connecting end 1311 from deformation or breakage.

[0050] See also Fig. 9 The first connection hole 1314 has a side edge 1315, the side edge 1315 is adjacent to the first U-shaped hook portion 132, and the side edge 1315 is provided with a clearance gap 1316. Since the first U-shaped hook portion 132 is difficult to pull during installation, an installation rope 300 is required for assistance, and the installation rope 300 is provided with a buckle portion 310. The clearance gap 1316 is used to cooperate with the buckle portion 310. When in use, the buckle portion 310 is buckled into the clearance gap 1316, and then the installation rope 300 is pulled, so as to achieve the purpose of convenient installation.

[0051] See also Figures 5 to 7, the diameter of the column 1453 gradually increases from the middle to both ends. Specifically, the column 1453 has an arc-shaped concave surface 1455. A fitting portion 1323 is provided on the first U-shaped hook portion 132, and the fitting portion 1323 matches the column 1453. Specifically, the thickness of the fitting portion 1323 decreases from the middle to both sides, and the fitting portion 1323 has an arc-shaped convex surface 1324. When the first U-shaped hook portion 132 and the column 1453 are connected, the fitting portion 1323 can fit the column 1453 in a matching manner. When the first U-shaped hook portion 132 is hooked on the column 1453, the first U-shaped hook portion 132 can swing up and down and left and right.

[0052] The rest of this embodiment is the same as that of Embodiment 1. The features not explained in this embodiment are all based on the explanations in Embodiment 1 and will not be described in detail here.

[0053] Example 3

[0054] The difference between this embodiment and embodiment 1 is: Figures 10-12 The hook member 130 b is a horizontal second U-shaped hook portion 134 , and the second U-shaped hook portion 134 is integrally formed with the first top end 221 .

[0055] See also Fig.11 The hook member 140b has a second bottom surface 148, a protrusion 149 is formed on the second bottom surface 148, a second hook hole 1491 is formed on the protrusion 149, and the second hook hole 1491 passes through the protrusion 149. A second connecting hole 146 is formed at one end of the hook member 140b, and a second hook 147b is formed at the other end.

[0056] One end of the flexible belt is fixedly connected to the cushion 210, and the other end thereof can movably pass through the hook hole member 140b and be fixedly connected to the cushion 210. Specifically, the other end of the flexible belt can movably pass through the second connection hole 146.

[0057] During installation, the elastic rod 220b is pressed close to the hook hole member 140b, and the second U-shaped hook portion 134 passes through the second hook hole 1491. The elastic rod 220b is released to reset, and the elastic force of the elastic rod 220b acts on the extension member 110 through the hook hole member 140b, so that the extension member 110 is straightened and tightened, and the second U-shaped hook portion 134 is tightly stuck in the second hook hole 1491. During disassembly, the elastic rod 220b is pressed, and the second U-shaped hook portion 134 is disengaged from the second hook hole 1491, thereby separating the second U-shaped hook portion 134 and the hook hole member 140b.
