In other embodiments, the number of the side bars 11 may also be three, four or other numbers. . The support frame 1 is generally annular, and the side bars 11 are all curved so as to form a circular ring.

The side bar 11 is an arc formed by bending a circular tube, and the ends of the adjacent two side bars 11 are sleeved with each other and fixedly connected by bolts, and the round tubular side bar 11 can improve the structural strength thereof, and at the same time, the side bar 11 is convenient. The assembly connection between the two.

The support frame 1 is provided with a plurality of support legs 12, and the plurality of support legs 12 are arranged along the support frame 1 in the axial direction. Each support leg is vertically disposed, and its top end is welded to the side bar 11. The side bars 11 can be supported to a certain height by using the plurality of support legs 12, so that the jump pads 2 can be floated up and down. The joint strength between the side bar 11 and the support leg 12 can be enhanced by welding, and the stability of the support frame 1 and the trampoline can be enhanced. Further, the support legs 12 are welded one-to-one with the side bars 11, that is, six support legs 12 are also welded to the six side bars 11, respectively. The provision of a support leg 12 for each side bar 11 simplifies the structure while satisfying the bearing strength and effectively improving the stability of the entire boring machine. Here, in other embodiments, two or other numbers of support legs 12 may be welded to one of the side bars 11, or only the side legs 11 may be welded with the support legs 12.

The top end of the support leg 12 is welded to one end of the side bar 11. Since the side bar 11 is curved, the support leg 12 is connected to one end of the side bar 11, and in the state where the trampoline is disassembled, the integral storage of the side bar 11 and the support leg 12 can be facilitated. Here, in other embodiments, the top end of the support leg 12 may also be welded to the middle portion or other portions of the side bar 11. A rubber pad 13 can be attached to the bottom end of the support leg 12 to prevent damage to the ground from the bottom end of the support leg 12. Preferably, the support foot 12 can also be round tubular.

Further, as shown in FIG. 6, the trampoline further includes a single-bar armrest frame 4 including a riser 41, an adjustment rod 42, an armrest 43, and a locking screw 44. The riser 41 is fixedly coupled to the support frame 1. The top end of the adjusting rod 42 is fixedly connected to the armrest 43 and the adjustable rod 42 is sleeved in the riser 41 for adjusting the height of the armrest 43. The locking screw 44 is threaded through the wall of the tube 41. The inner end of the locking screw 44 can be coupled to the adjustment rod 42 to secure the relative position of the adjustment rod 42 to the riser 41. Rotating the locking screw 44 in the radial direction of the riser 41 allows the inner end of the locking screw 44 to be mated with the adjustment rod 42. Here, a through hole may be formed in the riser 41, and a nut is welded on the pipe wall of the riser, and the lock screw 44 is screwed with the nut to realize the threading of the lock screw 44 to establish the pipe wall of the pipe 41, of course. In other embodiments, a threaded hole may be formed in the wall of the riser, and the locking screw 44 is screwed to the threaded hole.

The adjusting rod 42 is tubular, and a plurality of positioning holes 420 are defined in the tube wall. The plurality of positioning holes 420 are arranged along the axial direction of the adjusting rod 42 , and the inner end of the locking screw 44 can penetrate into the positioning hole 420 . When the locking screw 44 moves outward to separate the inner end from the riser 41, the adjusting rod 42 can move up and down. When the locking screw 44 moves inward and the inner end enters the positioning hole 420, the adjusting rod 42 is opposite to the vertical The relative position of the tube 41 is fixed. Here, as another embodiment, the adjusting rod 42 may not have a positioning hole 420, and the inner end of the locking screw 44 may abut against the adjusting rod 42 to lock the adjusting rod 42 in the riser 41, thereby The relative position between the riser 41 and the adjustment rod 42 is locked.

A damping sleeve 412 is disposed between the adjusting rod 42 and the riser 41 to prevent wear between the adjusting rod 42 and the riser 41 due to mutual friction. The top end of the adjusting rod 42 is bent toward the inner side of the support frame 1, so that the armrest 43 can be relatively close to the inner side of the support frame 1, so that the user can hold the armrest 43 while jumping, and the armrest 43 can enhance the user's bouncing. A sense of security. In this embodiment, the armrest 43 is T-shaped so that the user can hold the armrest 43 with both hands. A rubber sleeve 431 is sleeved on the armrest 43 to improve the comfort of the user.

In the present embodiment, the single-bar armrest frame 4 supports the armrest 43 only through one riser 41 and one adjustment rod 42. The structure is simple and easy to assemble. The use of the armrest 43 allows the user to be more stable in bouncing and enhance the user's sense of security. The adjustment lever 42 can be adjusted up and down, and the armrest 43 can be adjusted to a suitable height for use by users of different heights.

As shown in FIG. 7, the riser 41 is fixedly coupled to a support leg 12 via a spacer 45, and the spacer 45 is disposed between the riser 41 and the support leg 12. The spacer 45 is vertically disposed in a strip shape. There are two The mounting slots 450 and the two mounting slots 450 respectively cooperate with the riser 41 and the support legs 12. Since the riser 41 and the support leg 12 are both round tubular in this embodiment, the mounting groove 450 is disposed in a concave arc shape to facilitate the corresponding cooperation between the spacer 45 and the riser 41 and the support leg 12.

The mounting tool 9 has an elongated shape as a whole, and includes two mounting rods 91 arranged side by side. A gap is formed between the two mounting rods 91. The sleeve formed by the elastic cord 31 can be formed by the gap between the two mounting rods 91. The ring expands a certain space to facilitate sliding the connecting ball into the collar. One end of the two mounting rods 91 is fixedly coupled together, and the other ends of the two mounting rods 91 are bent to form a hook 92, and a gap is provided between the two hooks 92. Preferably, the two mounting rods 91 are integrally formed, that is, the two mounting rods 91 can be formed by bending a metal rod into a U shape to improve the structural strength between the two mounting rods 91. During assembly, on the one hand, the two hooks 92 can be used for hooking onto the side bars 11. On the other hand, the two hooks 92 can be respectively located on both sides of the connecting ball to clamp the connecting balls 32, thereby connecting the balls. A loop formed by a bungee cord is worn to hook the connecting ball to the bungee cord. Further, one end of the two mounting rods 91 provided with the hooks 92 is fixedly connected by a fixing rod 93 to improve the structural strength at the two hooks 92.

When the jump mat 2, the elastic cord 3 and the side rod 11 are assembled, first, the elastic cord 31 is placed in a double-stranded loop belt 21, and the connecting ball 32 is blocked at one end of the loop belt 21, and the mounting tool 9 is provided. One end of the hook 92 passes through the collar formed by the elastic cord 31 and hooks the edge of the side bar from above. Then, the mounting tool 9 is rotated to the outside of the side bar centering on the side bar so that the hook 92 is located below the side bar and then hung The hook 92 is pushed toward the inside of the side bar so that the hook 92 hooks the connecting ball 32. Finally, the mounting tool 9 is gripped and depressed to push the connecting ball 32 into the collar formed by the elastic cord 31, and the connecting ball 32 will slide into the collar of the elastic cord 31 by itself under the sidebar 11. With the installation tool 9, the elastic force of the elastic cord 31 can be overcome, and the jump mat 2, the elastic cord 3 and the side rod 11 can be assembled quickly and easily.

The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It is the scope of protection of the present invention.
