Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to a frame for a trampoline and a trampoline. Background Art

[0002] The frame of a trampoline and the trampoline itself are usually composed of various materials and are carefully designed and manufactured to ensure the structural stability and safety of use. First of all, the frame of a trampoline mainly adopts a rigid structure, such as a steel frame structure, a composite alloy structure or other metal frameworks. These structures have a certain load-bearing capacity and can withstand various forces generated during the use of the trampoline. Among them, the steel structure is a common choice for the trampoline frame because it is not only strong and durable but also relatively low in cost. In addition, the connection parts of the frame are usually fixed with rivets or other fasteners to ensure its structural stability. The elastic net surface of the trampoline is the core part of the trampoline and is usually made of materials such as high-strength fibers, nylon or PVC. These materials not only have good elasticity and extensibility but also can bear a large weight. To ensure the safety of users, the load-bearing capacity of the trampoline is required to reach at least more than 200 kilograms. In addition, some high-end trampolines also use special springs or elastic systems to provide a more uniform and stable bouncing effect;

[0003] The design of the trampoline frame may be relatively complex, and the installation process requires certain skills and patience. If the installation is improper, it may affect the stability and service life of the trampoline. Without shock absorption, the oscillation of the trampoline may cause damage to the user's body, especially to the internal organs of children who have not yet developed fully, such as the brain, which may have an adverse impact. Secondly, without shock absorption, during the bouncing process of the trampoline, due to the change in the direction and amplitude of the upward jump, the user may fall, thereby damaging the spine, joints, ligaments, etc. Summary of the Utility Model

[0019] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present utility model as follows.

[0020] Please refer to Figures 1 - 5 As shown, the purpose of this embodiment is to provide a frame for a trampoline, including a ring 1. Five disassembly and assembly devices 7 are arranged above the outer surface of the ring 1. A support rod 3 is fixedly connected to the outer surface of the disassembly and assembly device 7. Five support legs 6 are fixedly connected to the lower surface of the ring 1;

[0021] It also provides a trampoline, including a frame. A trampoline 2 is fixedly connected to the inner ring of the ring 1. A protective net 4 is fixedly connected to the arc surface of the support rod 3. An entrance and exit door 5 is arranged on the outer surface of the protective net 4. A shock absorption device 8 is arranged on the inner wall of the support leg 6;

[0022] The disassembly and assembly device 7 includes a thread adjusting rod 71. The upper end of the arc surface of the thread adjusting rod 71 is rotatably connected to a first limit block 73. The upper end of the outer surface of the thread adjusting rod 71 is fixedly connected to a second limit block 74. Through the cooperative action of the thread adjusting rod 71, the first limit block 73, and the second limit block 74, when the thread adjusting rod 71 rotates, the disassembly and assembly device 7 can be quickly fixed and installed and disassembled;

[0023] The outer surface of the threaded adjusting rod 71 is rotatably connected to a base 72. A fixing ring 75 is sleeved on the outer surface of the base 72. The inner surface area size and shape of the fixing ring 75 are adapted to the outer surface area size and shape of the base 72. Through the cooperation of the base 72 and the fixing ring 75, the base 72 and the ring 1 are fixed, so that the base 72 is fixedly installed on the ring 1;

[0024] The inner wall of the fixing ring 75 is inserted and connected with a fixing cover 76. The fixing cover 76 includes a rotating hole for inserting the threaded adjusting rod 71. The outer surface area size and shape of the fixing cover 76 are adapted to the inner surface area size and shape of the fixing ring 75. A disassembly hole 77 is opened on the upper surface of the fixing cover 76. The inner surface area size and shape of the disassembly hole 77 are adapted to the outer surface area size and shape of the second limiting block 74. A fixing groove 78 is opened on the upper surface of the fixing cover 76. Through the cooperation of the disassembly hole 77 and the fixing groove 78, the threaded adjusting rod 71 can fix the support rod 3 on the ring 1. When not in use, the support rod 3 is removed, which mainly plays the role of fixing and disassembling the support rod 3;

[0025] A positioning block 79 is fixedly installed on the lower surface of the base 72. A bolt 710 is threadedly connected to the inner walls of the positioning block 79, the base 72 and the ring 1. A jack 711 is opened on the outer surface of the ring 1. The inner surface area size and shape of the jack 711 are adapted to the outer surface area size and shape of the base 72. Through the cooperation of the positioning block 79 and the bolt 710, when the threaded adjusting rod 71 rotates, the base 72 will not rotate together with the threaded adjusting rod 71;

[0026] It should be noted that the fixing cover 76 is fixed to the bottom end of the support rod 3. At the same time, the inside of the support rod 3 is hollow, and the threaded adjusting rod 71 can be inserted into it.

[0027] The shock absorption device 8 includes a connection hole 81 opened on the inner wall of the support leg 6. A damper 82 is inserted and connected to the inner wall of the connection hole 81. Through the action of the damper 82, the oscillation of the trampoline is reduced, and damage to the child's body is avoided;

[0028] One side of the outer surface of the damper 82 is fixedly connected to a support plate 83. Fixing components 84 are arranged on both sides of the outer surface of the support plate 83. The fixing components include a fixing plate, a fixing hole, a threaded groove and a bolt. When the damper 82 is placed in the connection hole 81, the support plate 83 is fixed to the support leg 6. Through the action of the support plate 83, the trampoline 2 is placed more stably.

[0029] When the utility model is specifically used, the damper 82 with the support plate 83 is inserted into the connection hole 81 below the support leg 6, and then the damper 82 is fixed on the support leg 6 by the fixing component 84. Then, the frame is installed. The base 72 with the threaded adjusting rod 71 is inserted upward through the jack 711 from below the ring 1. Then, the fixing ring 75 is sleeved on the base 72, and then the fixing cover 76 is inserted into the fixing ring 75, so that the disassembly hole 77 on the fixing cover 76 is aligned with the second limiting block 74 and passes through the second limiting block 74. The bolt 710 passes through the positioning block 79 and the base 72 and is inserted into the ring 1. By using the threaded connection between the bolt 710 and the positioning block 79, the base 72 and the ring 1, the three can be fixed together. Then, the threaded adjusting rod 71 is rotated to rotate the second limiting block 74 into the fixing groove 78 to limit the base 72, so that the fixing cover 76 with the support rod 3 can be fixed on the base 72, and further the protective net 4 can be fixed directly above the trampoline 2. Finally, the trampoline is placed firmly. When in use, open the access door 5 to enter the trampoline 2 to play. The protective net 4 prevents children from falling out of the trampoline 2 and causing injuries during play.
