Further technical scheme, the junction of supporting leg and external pipe is equipped with the strengthening rib.

In a further technical scheme, an integrally formed reinforcing protection pad is arranged on the outer ring of the bottom of the rubber pad.

According to a further technical scheme, the inner connecting pipe and the outer connecting pipe are made of metal square pipes, and the supporting legs are made of stainless steel round pipes.

The utility model has the advantages that:

the utility model discloses prior art center sectional frame's structure has been simplified greatly, by the intervalve that a plurality of structures are the same, the connector assembly is constituteed, the size that adopts the section bar is only three kinds, intervalve and connector rigid's connection back each other, external pipe can form a closed circular frame with the intervalve, establish at the mounting hole through hanging between inner union pipe and the intervalve, the spring hook of fixed orifices department is connected fixedly, the quantity of spare part has been reduced, the effectual preparation cost that reduces trampoline ring frame, convenience of customers assembles the dismantlement.

Drawings

FIG. 1 is a schematic structural view of the present invention,

figure 2 is a schematic exploded view at a in figure 1,

the device comprises a middle pipe 1, a middle pipe 11, a pipe orifice 12, a mounting hole 2, a connecting joint 21, an inner connecting pipe 211, a fixing hole 22, an outer connecting pipe 23, supporting legs 24, reinforcing ribs 3, rubber pads 31 and a reinforcing protection pad.

Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in fig. 1-2, the utility model provides a trampoline ring frame structure of elastic trampoline, including six at least intermediate pipes 1, six at least connector 2, in this embodiment, by six intermediate pipes 1, six connector 2 assembly are constituteed, evenly distributed has a plurality of mounting holes 12 that are used for installing the spring hook on every intermediate pipe 1, every connector 2 includes interior union coupling 21, outer union coupling 22, supporting leg 23, interior union coupling 21 and outer union coupling 22 are the metal square pipe and make, supporting leg 23 is the stainless steel pipe.

The outer pipe 22 is sleeved on the outer wall of the inner pipe 21 and is welded and fixed with the inner pipe 21, the end portions of the left end and the right end of the inner pipe 21 extend outwards to form a connecting portion, the two ends of the middle pipe 1 are provided with pipe orifices 11 for inserting the connecting portions, the connecting portions are provided with fixing holes 211 corresponding to the mounting holes 12, the supporting legs 23 are fixed under the outer pipe 22, and reinforcing ribs 24 are arranged at the connecting portions of the supporting legs 23 and the outer pipe 22.

Through the inner wall of taking over 22 outward and the outer wall welded fastening of inner joint pipe 21, supporting leg 23 is equipped with the strengthening rib with the junction of taking over 22 outward, has strengthened the intensity of trampoline ring frame junction to further increased the utility model discloses a mechanism stability.

Rubber pads 3 are fixedly installed at the bottoms of the supporting legs 23, and integrally formed reinforcing protection pads 31 are arranged on the outer rings of the bottoms of the rubber pads 3. The reinforcing protection pad 31 not only increases the wrapping performance of the rubber pad 3 on the supporting leg 23, but also increases the contact area between the bottom and the ground, and effectively improves the stability of the supporting leg 23.

After the intermediate pipes 1 and the connecting joints 2 are rigidly connected to each other, i.e. after each connecting part is inserted into the pipe orifice 11 of an adjacent intermediate pipe 1, the extension pipe 22 forms a closed circular frame with the intermediate pipe 1. Therefore, the cross sections of the inner connecting pipe 21, the outer connecting pipe 22 and the middle pipe 1 are all arc-shaped structures, the phenomenon that the joint of the middle pipe 1 and the inner connecting pipe 21 is deformed to cause torsion dislocation is avoided, the mounting hole 12 and the fixing hole 211 are overlapped at the moment, the spring is mounted at the position, and after the hook at the end part of the spring is clamped in the mounting hole 12 (the fixing hole 211), the connection and the reinforcement between the middle pipe 1 and the connecting joint 2 are realized.

To sum up, the utility model discloses simplified the structure of composite frame among the prior art greatly, in order to guarantee circular frame's overall stability, the utility model discloses an at least six intermediate pipes 1 that the structure is the same, attach fitting 2 assemble and constitute, and the section bar size that production preparation adopted is only three to reduced the use of fastening spare part, the effectual preparation cost that reduces the trampoline ring frame, convenience of customers assembles the dismantlement.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
