[0030] like Figures 1-8 As shown in the figure, as an embodiment of the present invention, a support device for a trampoline is provided, including a trampoline 1 for supporting a user's jumps and a mounting frame 3 for mounting the trampoline 1. Several elastic connectors 2 are connected around the trampoline 1. The mounting frame 3 has a hollow area 30 in the middle for placing the trampoline 4 and allowing the trampoline 4 to move up and down. Several mounting holes 5 for the elastic connectors 2 to pass through are arranged around the hollow area 30 on the mounting frame 3. Several support portions 6 are arranged on the top of the mounting frame 3 corresponding to the elastic connectors 2, and several filling portions 7 are arranged along the periphery of the hollow area 30. The mounting holes 5 penetrate the support portions 6. A first connecting mechanism 4 is provided below the support portions 6 for locking the end of the elastic connector 2 away from the trampoline 1 onto the mounting frame 3. Each filling portion 7 is located between the opposite sides of two adjacent elastic connectors 2 and arranged along the outer end of the trampoline 1. When the elastic connector 2 switches from its initial state to its deformed state, the surface of the support portion 6 abuts against the lower surface of the elastic connector 2 to support the elastic connector 2. In this embodiment, the supporting device has one end of its elastic connector 2 connected to the jump cloth 1, and the other end passing through the mounting hole 5 and connected to the first connecting mechanism 4, which locks it onto the mounting frame 3. Since a filling part 7 is arranged between the opposite sides of two adjacent elastic connectors 2 and along the outer end of the jump cloth 1, there is no need for an additional jump cloth cover. The filling part 7 can directly fill the gaps between the mounting frame 3, the jump cloth 1, and the adjacent elastic connectors 2, preventing accidental injury to children's hands, feet, or other body parts from falling into these gaps during jumping, thus improving the safety of the trampoline. Furthermore, the elimination of the jump cloth cover reduces the cumbersome steps of assembling it, enabling rapid assembly. In addition, when the elastic connector 2 switches from its initial state to its deformed state, the surface of the support part 6 abuts against the lower surface of the elastic connector 2 to support it. This allows the mounting frame 3 and the first connecting mechanism 4 to jointly provide support for the elastic connector 2 and the jump cloth 1, enhancing the stability and load-bearing capacity of the mounting frame 3 in supporting the elastic connector 2 and the jump cloth 1.

[0031] like Figure 2As shown in the drawings, in some embodiments, the hollow region 30 is shaped to match the shape of the jump cloth 1, and the two filling parts 7 are respectively connected to the opposite sides of the two adjacent support parts 6, and the jump cloth 1 side of each filling part 7 and the jump cloth 1 side of each support part 7 are arranged around the hollow region 30, that is, the shape of the hollow region 30 is set to a shape that matches the jump cloth 1 more closely, so that the filling part 7 can more completely fill the gap between the mounting rack 3, the jump cloth 1, and the two adjacent elastic connecting pieces 2. In this embodiment, when the elastic connecting piece 2 is in the initial state, the jump cloth 1 side of the filling part 7 is in contact with the outer side end of the jump cloth 1, thereby further reducing the gap range and improving the safety during use. In other embodiments, the gap between the jump cloth 1 side of the filling part 7 and the outer side end of the jump cloth 1 can be set to be less than or equal to 2 cm, especially less than 0.5 cm, when the elastic connecting piece 2 is in the initial state, which can also better prevent children's legs, feet, and other body parts from falling into the gap.

[0032] As shown in the drawings, Figure 3 In some embodiments, the filling part 7 extends from the inner end of the mounting rack 3 to a position close to the outer end of the mounting rack 3, and the top surface of the filling part 7 is arranged along the top surface of the mounting rack 3 and is flush or substantially flush with the top surface of the mounting rack 3, so that the top surface of the mounting rack 3 is relatively flat, which can avoid injury caused by knocking against the filling part 7 when falling, and improve the safety of use.

[0033] As shown in the drawings, Figure 7 In some embodiments, the mounting hole 5 is connected between the top of the side wall close to the hollow region 30 and the surface of the support part 6 through a beveled circular arc surface 51 inclined to the hollow region 30, and the circular arc surface 51 is in contact with the elastic connecting piece 2, which can avoid scratching the lower surface of the elastic connecting piece 2, thereby prolonging the service life of the elastic connecting piece 2. In other embodiments, the circular arc surface 51 can also be set as a beveled surface inclined to the hollow region 30, which can also reduce the scratching of the lower surface of the elastic connecting piece 2 compared to setting it as a right-angled surface.

[0034] As shown in the drawings, Figure 3 , 7As shown, in some embodiments, the support part 6 is a sunken groove arranged on the top surface of the mounting frame 3 and extending from the inner side end to the outer side end of the mounting frame 3, that is, extending from the side end close to the hollow area 30 to the side end away from the hollow area 30 of the mounting frame 3. The mounting hole 5 is arranged at the groove bottom area of the sunken groove, and the groove opening 60 close to the bottom of the hollow area 30 is lower than the top surface of the mounting frame 3. The elastic connecting member 2 is arranged along the sunken groove through the groove opening 60 to the corresponding mounting hole 5 and connected with the first connecting mechanism 4 through the mounting hole 5. When the elastic connecting member 2 switches from the initial state to the deformed state, the groove bottom surface of the sunken groove abuts against the lower surface of the elastic connecting member 2 to support the elastic connecting member 2. In this embodiment, the structure of the sunken groove is arranged so that all or part of the structure of the elastic connecting member 2 is arranged to be sunken relative to the top surface of the mounting frame 3, thereby reducing the height of the elastic connecting member 2 protruding from the top surface of the mounting frame 3, so that the top surface structure formed by the top surface of the mounting frame 3 and the top surface of the elastic connecting member 2 is relatively flat, which can avoid the risk of falling caused by the elastic connecting member 2 scratching the body parts such as legs and feet during the user's jumping use, thereby improving the safety of use. In this embodiment, the elastic connecting member 2 is arranged as an elastic band, both ends of which are sewn and connected to the jumping cloth 1, and a sleeve connecting channel is formed in the middle. The elastic band is arranged in a flat structure, which is simple in structure and convenient for stable storage in the sunken groove, and can be curled and deformed to facilitate the connection with the first connecting mechanism 4 by being inserted into the mounting hole 5, and can be tensioned and deformed along the surface of the support part 6 with the deformation of the jumping cloth 1. In other embodiments, the elastic connecting member 2 can also be arranged in other shapes, or arranged as an elastic rope or other structure that can provide elastic driving force for the jumping cloth 1.

[0035] As shown, Figure 3 In some embodiments, the mounting hole 5 is arranged as a strip-shaped through hole matched with the elastic band and arranged close to the outer end of the mounting frame 3, that is, the distance between the mounting hole 5 and the inner end of the mounting frame 3 is greater than the distance between the mounting hole 5 and the outer end of the mounting frame 3, thereby increasing the surface length of the support part 6, so that the contact surface between the surface of the support part 6 and the elastic connecting member 2 is larger, which is more conducive to improving the stability and load-bearing capacity of the mounting frame 3 supporting the elastic connecting member 2.

[0036] In some embodiments, the sinking groove has a first side wall 61 and a second side wall 62 arranged opposite to each other, and a strip-shaped through hole is arranged between the first side wall 61 and the second side wall 62 in a bottom region of the groove, so that the part of the elastic connecting piece 2 arranged above the strip-shaped through hole can be accommodated in the sinking groove, the flatness of the connecting region between the elastic connecting piece 2 and the top surface of the mounting frame 3 is improved, and the safety during use is further improved. The sinking groove also has a third side wall 63 arranged close to the outer end of the mounting frame 3 and connected to the first side wall 61 and the second side wall 62 at both ends, respectively. The inner side of the leading end of the strip-shaped through hole extends upward and is connected to and flush with the first side wall 61. The inner side of the trailing end of the strip-shaped through hole extends upward and is connected to and flush with the second side wall 62. The side of the strip-shaped through hole away from the hollowed-out region 30 is connected to and flush with the third side wall 63. The structure is compact. The inner side of the leading end of the strip-shaped through hole is arranged as a corresponding arc surface with the first side wall 61, and the trailing end of the strip-shaped through hole is arranged as a corresponding arc surface with the second side wall 62, which can avoid scratching the two side edges of the elastic connecting piece 12 and prolong the service life of the elastic connecting piece 12.

[0037] As shown in Figures 4-8 In some embodiments, the first connecting mechanism 4 includes a first fixing piece 41 arranged on the mounting frame 3, and a connecting rod 42 arranged transversely corresponding to the first fixing piece 41. The first fixing piece 41 has a first positioning region 43 formed therein to communicate with the corresponding mounting hole 5, and the first positioning region 43 is used to arrange the elastic connecting piece 2. The first connecting mechanism 4 also includes a second fixing piece 44 arranged on the mounting frame 3, and a connecting rod 42 arranged transversely corresponding to the second fixing piece 44. The second fixing piece 44 has a second positioning region 45 formed therein to communicate with the corresponding mounting hole 5, and the second positioning region 45 is used to arrange the elastic connecting piece 2. During assembly, each elastic connecting piece 2 is inserted into the corresponding mounting hole 5, and the end of the elastic connecting piece 2 away from the mat 1 is sleeved on the middle of the connecting rod 42. The two ends of the connecting rod 42 protrude from the two sides of the elastic connecting piece 2, respectively, and are detachably connected to the corresponding first fixing piece 41 or second fixing piece 44. The surface of the connecting rod 42 abuts against the inner surface of the elastic connecting piece 2 to support the elastic connecting piece 2. Thus, each elastic connecting piece 2 can be installed or detached from each first fixing piece 41 or second fixing piece 44 through the corresponding connecting rod 42. Compared with connecting multiple elastic connecting pieces 2 and the mounting frame 3 through one connecting rod at the same time, the support device of the present embodiment is easier to assemble, more labor-saving, and convenient for individually adjusting each elastic connecting piece 2.
