Description

Technical Field

[0001] This utility model relates to the field of trampoline frames, and more particularly to a novel trampoline frame. Background Technology

[0002] A trampoline support frame is a structure used to support a trampoline. It is usually made of metal or other sturdy materials and is designed to provide stable support to ensure the safety of the trampoline during use. Trampoline support frames can come in various forms, including round, square, and polygonal, to accommodate different types and sizes of trampolines.

[0003] Square trampoline frames with four legs are usually fixed to the top of the trampoline by welding. Because stress concentration may occur at the weld, cracks may easily form due to the trampoline's shaking after long-term use, resulting in relatively weak stability of the trampoline.

[0004] Therefore, in view of the above-mentioned situation where stress concentration may occur at the welding points, and the square trampoline frame supported by four legs is usually fixed to the upper end of the trampoline by welding, so that the trampoline is prone to cracking due to shaking after long-term use, a new type of trampoline frame can be designed to increase the stability of the trampoline frame by means other than welding, and to increase the convenience of trampoline frame assembly. Utility Model Content

[0005] To overcome the problem that trampolines are prone to cracking due to shaking after long-term use, since the square trampoline frame with four legs is usually fixed to the top of the trampoline by welding, and stress concentration may occur at the weld, the trampoline is prone to cracking due to shaking.

[0006] The technical solution of this utility model is as follows: a novel trampoline frame, comprising four interconnected outer support walls; and a central rod. Each end of the outer support wall has a clamping groove. The central rod is inserted into the clamping grooves on two adjacent outer support walls. A cover block is fixed to the upper end of the central rod, and two locking strips are fixed to the cover block. Slots are provided on both sides of the upper end of each outer support wall. A support ring is provided at the lower end between the four outer support walls. Four inner support arms are fixed to the support ring, and the inner support arms are in contact with the side ends of the outer support walls. Foot buckles are slidably connected to the lower ends of two adjacent outer support walls, the central rod, and the inner support arms.

[0007] Preferably, when assembling the trampoline, the four inner support arms are inserted into the four foot buckles respectively, then the two interlocking outer support walls are inserted into the inner support arms, and the center rod is inserted into the slots opened on the two adjacent outer support walls. At the same time, the locking strip is also inserted into the slots to assist in positioning the outer support walls through the center rod, cover block and locking strip. Finally, the first bolt is tightened to fix the outer support walls and the slots together, and then the inner support arms are tightened to fix the inner support arms, center rod and outer support walls together, so as to realize the quick assembly of the trampoline frame. When the trampoline frame is shaken, the outer support walls at different positions will transmit the force to each other through the center rod to disperse the force and suppress the amplitude of the shaking. The force on the center rod will also be transmitted to the support ring through the inner support arms to further increase the structural strength and further disperse the force.

[0008] Preferably, the two adjacent outer support walls are threaded together with two first bolts, and the first bolts pass through the central rod. The foot buckle is threaded with a second bolt, and the second bolt passes through the inner support arm, the central rod and the outer support wall.

[0009] Preferably, the card strip and the card slot are configured to slide together, and multiple first slots are fixed to the outer end of the outer support wall.

[0010] Preferably, the upper end of the cover block is fixedly connected to a second slot, and both the first and second slots are equipped with inserts.

[0011] Preferably, baffles are fixedly connected to the inserts on the same side, and a trampoline surface is provided at the upper end of the support ring.

[0012] Preferably, the lower end face of the trampoline surface is fixed with multiple connecting seats.

[0013] Preferably, each connecting seat is fixed with a tether rope, and the tether rope is looped around the outer support wall.

[0014] The beneficial effects of this utility model are:

[0015] By setting up outer support walls, a central rod, and support rings, the four inner support arms are inserted into the four foot buckles respectively during trampoline assembly. Then, two interlocking outer support walls are inserted into the inner support arms, and the central rod is inserted into the slots opened on the two adjacent outer support walls. At the same time, the locking strips are also inserted into the slots to assist in positioning the outer support walls through the central rod, cover blocks, and locking strips. Finally, the first bolt is tightened to fix the outer support walls and the slots together. Then, the inner support arms are tightened to fix the inner support arms, the central rod, and the outer support walls together, thus achieving rapid assembly of the trampoline frame. When the trampoline frame is shaken, the outer support walls at different positions will transfer the force to each other through the central rod to disperse the force and suppress the amplitude of the shaking. The force on the central rod will also be transferred to the support ring through the inner support arms to further increase the structural strength and further disperse the force. This adds extra stability to the trampoline frame in a way other than welding and increases the convenience of trampoline frame assembly. Attached Figure Description

Four inner support arms 8 are fixed to the support ring 9, and the inner support arms 8 are attached to the side ends of the outer support walls 1. Adjacent outer support walls 1, the central rod 3, and the lower ends of the inner support arms 8 are slidably connected by foot buckles 10. When assembling the trampoline, the four inner support arms 8 are inserted into the four foot buckles 10 respectively, and then the two adjacent outer support walls 1 are connected together. The outer support wall 1 is inserted into the inner support arm 8, and then the center rod 3 is inserted into the slots 2 opened on the two adjacent outer support walls 1. At the same time, the locking strip 5 is also inserted into the slot 6 to assist in positioning the outer support wall 1 through the center rod 3, the cover block 4 and the locking strip 5. Finally, the first bolt 7 is tightened to fix the outer support wall 1 and the slot 2 together. Then, the inner support arm 8 is tightened to fix the inner support arm 8, the center rod 3 and the outer support wall 1 together to realize the quick assembly of the trampoline frame. When the trampoline frame is shaken, the outer support walls 1 at different positions will transmit the force to each other through the center rod 3 to disperse the force and suppress the amplitude of the shaking. The force at the center rod 3 will also be transmitted to the support ring 9 through the inner support arm 8 to further increase the structural strength and further disperse the force.

[0025] Please see Figures 3-6 In this embodiment, two first bolts 7 are threaded together on the side ends of two adjacent outer support walls 1, and the first bolts 7 pass through the central rod 3. The foot buckle 10 is threaded with a second bolt 11, and the second bolt 11 passes through the inner support arm 8, the central rod 3 and the outer support wall 1. The locking strip 5 and the locking groove 6 are configured to slide. Multiple first slots 12 are fixedly connected to the outer side end of the outer support wall 1. A second slot 13 is fixedly connected to the upper end of the cover block 4. Inserts 14 are installed in both the first slot 12 and the second slot 13. The inserts 14 and the baffle 15 are used to form a detachable guardrail.

[0026] Please see Figure 1 and Figure 6 In this embodiment, baffles 15 are fixedly connected to the inserts 14 on the same side. A trampoline surface 16 is provided at the upper end of the support ring 9. The trampoline surface 16 is used for users to jump. Multiple connecting seats 17 are fixedly connected to the lower end of the trampoline surface 16. A rope 18 is fixedly connected to each connecting seat 17. The rope 18 is looped on the outer support wall 1. The connecting seats 17 and the rope 18 are used to install the trampoline surface 16 on the trampoline bracket.

[0027] When assembling the trampoline, insert the four inner support arms 8 into the four foot buckles 10, then insert the two interlocking outer support walls 1 into the inner support arms 8. Next, insert the center rod 3 into the slots 2 opened on the two adjacent outer support walls 1. At the same time, the locking strip 5 is also inserted into the slot 6 to assist in positioning the outer support walls 1 through the center rod 3, the cover block 4, and the locking strip 5. Finally, tighten the first bolt 7 to fix the outer support walls 1 and the slots 2 together. Then tighten the inner support arms 8 to fix the inner support arms 8, the center rod 3, and the outer support walls 1 together, thus realizing the quick assembly of the trampoline frame.

[0028] When the trampoline frame is shaken, the outer support walls 1 at different positions will transmit the force to each other through the central rod 3 to disperse the force and suppress the amplitude of the shaking. The force at the central rod 3 will also be transmitted to the support ring 9 through the inner support arm 8 to further increase the structural strength and further disperse the force.

[0029] Through the above steps, by setting the outer support wall 1, the central rod 3, and the support ring 9, the four inner support arms 8 are inserted into the four foot buckles 10 respectively during trampoline assembly. Then, two interlocking outer support walls 1 are inserted into the inner support arms 8. The central rod 3 is then inserted into the clamping grooves 2 opened on the two adjacent outer support walls 1. At the same time, the locking strip 5 is also inserted into the locking groove 6 to assist in positioning the outer support walls 1 through the central rod 3, the cover block 4, and the locking strip 5. Finally, the first bolt 7 is tightened to fix the outer support wall 1 and the clamping groove 2 together, and then the inner support ring 9 is tightened. Arm 8 fixes the inner support arm 8, the central rod 3, and the outer support wall 1 together to achieve a quick assembly of the trampoline frame. When the trampoline frame is shaken, the outer support walls 1 at different positions will transmit the force to each other through the central rod 3 to disperse the force and suppress the amplitude of the shaking. The force at the central rod 3 will also be transmitted to the support ring 9 through the inner support arm 8 to further increase the structural strength and further disperse the force. This will increase the stability of the trampoline frame in a way other than welding and increase the convenience of assembling the trampoline frame.
