Referring to fig. 1 and 2, the square trampoline frame provided by the present invention is formed by four arc-shaped frame pipes 10a and four straight frame pipes 10b which are connected end to end and enclosed. One end of a connecting pipe 20 is fixedly arranged at one of the connecting ends 11, 11' of two adjacent frame pipes 10, the outer diameter of the connecting pipe 20 is equal to or slightly smaller than the inner diameter of the frame pipe 10, and the other end of the connecting pipe 20 is inserted into the connecting end of the other adjacent frame pipe 10; the bottom surfaces of two ends of the straight frame tube 10b are respectively and fixedly provided with an inserting tube 21. The connecting pipe 20 and the inserting pipe 21 are fixedly arranged with the frame pipe 10 by conventional methods such as welding, screwing, riveting and the like, and welding is preferred.

In an embodiment of the present invention, as shown in fig. 2, two ends of the straight frame tube 10b are respectively fixed to one end of a connection tube 20.

In one embodiment of the present invention, two ends of the arc-shaped frame tube 10a are respectively fixed to one end of a connection tube 20.

In some embodiments of the present invention, each of the connection pipes 20 is fixedly disposed at a connection end of a left side of each of the frame pipes 10; or each of the connection pipes 20 is fixedly installed at the connection end of the right side of each of the frame pipes 10.

A support frame 50 is provided below the trampoline frame. The number of the support frames 50 is 4, and the support frames are uniformly distributed below the square trampoline frame, and each support frame 50 is connected with an arc-shaped frame pipe 10a and two straight frame pipes 10b at two sides of the arc-shaped frame pipe 10 a. When a person bounces on the trampoline mat, the supporting frame 50 is stressed in a balanced manner, so that the stability of the trampoline is maintained, and the trampoline is prevented from collapsing due to uneven stress.

The support frame 50, the connecting pipe 20 are connected with the frame pipe 10, and the inserting pipe 21 is connected with the support frame 50 and the frame pipe 10. When jumping on the trampoline, the jumping pad of the trampoline is stressed to the frame pipe and the arc frame pipe which are straightened towards the center of the trampoline, the frame pipe and the frame pipe are stressed unevenly, and the frame pipe are easily twisted and deflected towards the center of the trampoline. To solve the problem, the supporting frame 50 comprises a horizontal cross pipe 51 and two vertical pipes 52 extending upwards from two ends of the horizontal cross pipe 51, wherein each vertical pipe 52 is provided with an upper part 521 and a lower part 522, the lower part 522 is obliquely arranged relative to the horizontal plane in the direction of the trampoline mat, the upper part 521 is arranged in a way of deviating from the extending direction of the lower part 522 to the vertical horizontal plane, so that an obtuse included angle is formed between the lower part 522 and the upper part 521; the upper part 521 is inserted into the insertion tube 21. Each straight frame tube 10b is supported at both ends by a vertical tube of two of the support brackets 50, tensioned and oriented, thereby preventing the straight frame tube 10b from bending or even rotating relative to the curved frame tube 10 a. The upper portion 521 is inserted into the insertion pipe 21, so that the trampoline is very simple and convenient to mount and dismount.

Furthermore, at each side of the square trampoline frame, the two inserting pipes are respectively positioned at the positions close to 1/3 and 2/3 of the side, so that the whole trampoline frame is uniform in shape and balanced in stress.

The two insertion tubes 21 of each straight frame tube 10b are connected by a reinforcing tube connection 15. When the mat pulls the straight frame tube 10a toward the center of the trampoline, the reinforcing tube 15 helps to maintain the straight frame tube 10a against bending toward the center of the mat due to the pulling force.

Preferably, an auxiliary reinforcing pipe 16 is connected between the reinforcing pipe 15 and the straight frame pipe 10a, and the auxiliary reinforcing pipe 16 further helps to maintain the shape of the straight frame pipe 10 a.

Further, the connection ends 11,11 ' of the adjacent frame pipes 10 are respectively provided with at least one pair of grooves 12 and protrusions 12 ' which are matched with each other, and the protrusions 12 ' are inserted and received in the grooves 12, thereby connecting the adjacent frame pipes 10. When the trampoline frame with the structure is assembled and disassembled, only the adjacent convex blocks 12' of the frame tubes 10 are required to be inserted into the grooves 12 or pulled out of the grooves 12, the trampoline frame is very easy and convenient to assemble and disassemble, and no extra tool or installation skill is required. The cooperation of the grooves 12 and the lugs 12' also prevents relative rotation of adjacent frame tubes 10, thereby maintaining the stability of the overall trampoline frame against deformation.

Preferably, the grooves 12 are more than 2 pairs and are uniformly distributed on the connecting end 11, and the protrusions 12 'are more than 2 pairs and are uniformly distributed on the connecting end 11'. This configuration allows the frame tubes 10 to be evenly stressed and further prevents the adjacent frame tubes from rotating relative to each other, making their structure more stable.

Alternatively, the grooves 12 and the protrusions 12 'are spaced apart from each other at the connecting end 11 or the connecting end 11'.

At each of the connection ends, at least one projection 12' is fixedly connected to the connection tube 20.

A plurality of upper frame holes 13a and lower frame holes 13b are formed in pairs at equal intervals on the top and bottom of the frame pipe 10, and the upper frame holes 13a and the lower frame holes 13b in pairs are alternately arranged. A plurality of upper jacks 14a and lower jacks 14b are arranged at the top and bottom of the connecting pipe in pairs at equal intervals, and the upper jacks 14a and the lower jacks 14b in pairs are arranged in a staggered manner; after the two ends of the connecting pipe are inserted into the adjacent frame pipes, each upper insertion hole 13a is correspondingly overlapped with one upper frame hole 14a, and each lower insertion hole 13b is correspondingly overlapped with one lower frame hole 14 b.

Figure 1 shows the trampoline in a smaller size, for example less than or equal to 14 inches. When the trampoline is large in size, for example, 17 inches or 20 inches, or more, the four-cornered arc-shaped frame pipes 10a are easily raised relative to the straight frame pipes 10b, and for this reason, the applicant has further developed a reinforcing member 60 for connecting the arc-shaped frame pipes 10a and the support frame 50 to prevent the arc-shaped frame pipes 10a from being raised.

As shown in fig. 3 and 4, the upper and lower ends of the reinforcing member 60 are fixedly coupled to the middle of the arc-shaped frame pipe 10a and the horizontal cross pipe 51 of the support bracket 50, respectively.

For the convenience of transportation and assembly, the horizontal cross tube 51 is provided with a first section 51a, a second section 51b and a third section 51c which are disconnected, the reinforcing member 60 is two parallel straight tubes, and the lower end of the reinforcing member 60 is connected with the third section 51 c. And the outer diameters of the first section 51a and the second section 51b are smaller than the inner diameter of the third section 51c, so that the first section 51a and the second section 51b can slide in the third section 51c when being installed.

When the curved frame tube 10a is pulled under the bouncing action, the relatively straight frame tube 10b tilts upward, and at this time, the reinforcing member 60 pulls the curved frame tube 10a downward, thereby playing a balance role and maintaining the stability of the trampoline.

Referring to fig. 5, preferably, the two parallel straight tubes of the reinforcing member 60 are connected by a horizontal tube to form an H-shaped tube, which is more stable in structure.
