The bouncing pad 10 is preferably circular, but may be any other shape, such as square, regular pentagonal, regular hexagonal, elliptical, etc. The frame 20 is a ring formed by splicing a plurality of pipe units 21. The ends of adjacent tube units 21 are provided with mutually matching tabs and sockets, respectively. The tabs are inserted into the sockets to connect adjacent tube units 21.
The frame 20 is preferably placed on the support legs 40, but may also be placed on the ground. Preferably, the tube unit 21 is placed on the support leg 40.
Referring to fig. 1, 2 and 3, the frame 20 is provided with a bottom end mounting structure for adjusting a mounting position of a bottom end of the flexible rod 30, and the bottom end mounting includes an upper insertion hole 24 provided at an upper side of the frame 20 and a lower insertion hole 25 provided at a lower side of the frame 20. Each pair of the upper jack 24 and the lower jack 25 is arranged in a staggered manner. The adjustment structure further comprises a sleeve 26 corresponding to each pair of the upper and lower receptacles 24, 25. The sleeve 26 is inserted into the upper insertion hole 24 and the lower insertion hole 25. The bottom end of the flexible rod 30 is inserted into the sleeve 26.
Referring to fig. 2, 3 and 4, in order to prevent the sleeve 26 from falling out of the lower insertion hole 25, the diameter of the bottom end 262 of the sleeve 26 is set smaller than the diameter of the main body 261 thereof. Specifically, the diameter of the lower insertion hole 25 is larger than the diameter of the bottom end 262 and smaller than the diameter of the main body 261, thereby preventing the sleeve 26 from falling out of the lower insertion hole 25.
Further, the top end 263 of the sleeve 26 is provided with a nozzle which is gradually enlarged in the radial direction, thereby facilitating the insertion of the bottom end of the flexible rod 30.

Preferably, the upper insertion hole 24 is provided as an oval hole, and two ends, designated as an a end and a B end, of the oval hole are located at the inner side and the outer side of the upper side of the frame, respectively. The elastic member 27 is inserted into the a end or the B end of the oval hole, thereby adjusting the position of the flexible rod 30 in the frame 20, and thus adjusting the tension of the bouncing pad and the elastic force thereof. Specifically, when the bottom end of the flexible rod 30 and the sleeve 26 pass through the upper insertion hole 24, they are inserted into the lower insertion hole 25. The flexible rod 30 and the sleeve 26 are pressed to be positioned at the B position by inserting the elastic member 27 at the a position, that is, the position where the upper insertion hole 24 is near the inside of the upper side of the frame 20. At this time, the tension of the flexible rod 30 to the bouncing pad 10 is large, and the elasticity of the bouncing pad 30 is high. When the elastic member 27 is inserted into the position B, that is, the position of the upper insertion hole 24 near the outer side of the frame 20, the flexible rod 30 and the sleeve 26 are pressed to the position a, the tension of the bouncing pad 10 is small, and the elasticity of the bouncing pad 30 is low.
Preferably, referring to fig. 5, two limiting grooves 28 are symmetrically dug in the middle of the hole wall of the upper jack 24. Referring to fig. 6, the side surface of the elastic member 27, which is tightly attached to the sleeve 26, is an inner side surface 271, the side surface, which is tightly attached to the hole wall, is an outer side surface 272, both the inner side surface 271 and the outer side surface 272 are arc surfaces, a clamping block 273 is arranged at the junction of the two arc surfaces, and the clamping block 273 and the limiting groove 28 are mutually matched in shape and can be mutually clamped.
Preferably, an upper protrusion 274 extends from the junction of the latch 273 and the outer side 272. The bottom of the outer side 272 of the elastic member 27 extends out of the lower protrusion 275. When the elastic member 27 is inserted into the upper insertion hole 24, the upper protrusion 274 and the lower protrusion 275 are respectively engaged with the periphery of the hole wall of the upper insertion hole 24 from the up-down direction of the upper insertion hole 24, thereby preventing the upper insertion hole 24 from falling off.
Preferably, referring to fig. 1 and 7, in order to facilitate the installation of the top of the flexible rod 30, a plurality of fastening structures 70 are provided on the periphery of the bouncing pad 10, the fastening structures 70 are in one-to-one correspondence with the flexible rod 30, and the top 31 of the flexible member 30 is detachably installed at a predetermined position on the periphery of the bouncing pad 10, so that the installation manner is labor-saving and convenient. Referring to fig. 3, the snap structure 70 includes a mounting member 71, a flexible strap 72, and at least one catch 73 fixedly disposed on the flexible strap 72. The flexible strap 72 is fixedly installed at the bottom of the bouncing pad 10, a through hole 723 is formed in the installation member 71, the clamping member 73 and the strap 72 can pass through the through hole 723, and after passing through, the clamping member 73 is rotated to be fixedly clamped at the hole opening of the through hole 723, so that the strap 72 is prevented from being pulled back from the through hole 723 under the action of pulling force; the top of the flexible rod 30 is received in the mounting member 71 so as to mount the top 31 of the flexible member 30 at a predetermined position of the bouncing pad 10.
Preferably, referring to fig. 8, in one embodiment of the present invention, the bottom of the mounting member 72 is provided with a receiving groove (not shown), and the top 31 of the flexible rod 30 is fixedly disposed in the receiving groove. Preferably, the receiving groove is provided in an extending direction of the top 31 of the flexible rod so as to facilitate insertion and matching of the top 31 of the flexible rod 31. In the embodiment shown in fig. 3, the mount 72 is shaped like a cube. It should be appreciated that the shape of the mounting member 72 is not limited to the shape shown in this figure, but may be spherical, polyhedral or any other shape. The present invention is not limited to the outer shape of the mounting member 72, and any change in the outer shape of the mounting member 72 without departing from the basic concept of the present invention should be considered as being within the scope of the present invention.
Preferably, referring to fig. 8 and 9, the mounting member 72 has a thin tube portion 721 and an enlarged head portion 722 provided at the tip of the thin tube portion 721. The distal end 31 of the flexible rod 30 is inserted into the thin tube 721 and fixedly coupled thereto. The thin tube part 721 is disposed in an extending direction of the top part 31 of the flexible rod so as to facilitate the insertion and matching of the top part 31 of the flexible rod 31. The head 722 is laterally provided with the through hole 723.
Referring to fig. 9, the head 722 has a larger lateral diameter than the thin tube 721, thereby increasing the contact area between the mounting member 71 and the trampoline 10, and more firmly supporting the trampoline 10.
Preferably, a stop 724 protrudes from the head 722 at the outlet of the through hole 723. The catching piece 724 can catch the catching piece 73, thereby preventing the catching piece 73 from sliding and retracting the through hole 723.
Specifically, referring to fig. 9, the head 721 has a rectangular parallelepiped shape, and the bottom surface thereof is integrally formed with the thin tube portion 721, which is provided with the through hole 723, laterally provided with large and small ends, and is tapered from the large end to the small end. The through holes 723 are provided in flat holes. The strap 72 and the catch 73 are both sheet-shaped so as to be able to pass through the through hole 723 in cooperation with the through hole. After passing through the through-hole 723, the catching member 73 is rotated by a certain angle so as to be caught at the orifice of the through-hole 723.
The holding member 73 can pass through one side of the through hole 713 and is held in the other side opening of the through hole 713. In the embodiment of the present invention, the catch 73 has a smaller short side and a longer long side. The short side of the holding member 73 is slightly smaller than the hole width of the through hole 713, and the long side of the holding member 73 is slightly larger than the hole width of the through hole 713. The structure is arranged so that the clamping piece 73 can pass from one side to the other side of the through hole 713, and the clamping piece 73 is rotated after passing through, so as to clamp the clamping piece 73 at the hole of the through hole 713.
It will be appreciated that the catch 73 matches the shape of the through hole 713. For example, when the chucking member 73 is provided in a long cylindrical shape, the through hole 713 should also be provided in a long cylindrical shape; when the holding member 73 is provided in the shape of a long cube, the through hole 713 must be correspondingly provided in the shape of a long cube. Referring to fig. 3 and 4, in a preferred embodiment of the present invention, the retaining member 73 is provided as an elongated cubic thin metal card. The through hole 713 is also provided as a long cube-shaped flat opening.
After the clamping piece 73 passes through the through hole 713, the clamping piece 73 is clamped at the hole on the other side of the through hole 713 along the length-diameter direction, so that the fixing of the strap 72 is realized, the strap 72 is prevented from retracting under the action of tensile force, and the top end of the flexible rod 30 is clamped at the preset position of the periphery bottom of the bouncing pad 10.
It will be appreciated that the location of the catch 73 on the strap 72 must meet the design objective of "mounting the top end of the flexible rod 30 at a predetermined location around the trampoline 10. Therefore, the position where the catch 73 is mounted on the strap 72 is appropriate. The catch 73 is too far from the bouncing pad 10 or too close to it, which does not achieve the design objective.
The strap 72 is fixedly disposed on the trampoline 10. It should be appreciated that the flexible strap 72 may be secured to the bottom of the trampoline 10 in a variety of ways, such as by welding, snap-fit, or the like, as is conventional. In the preferred embodiment of the invention, the flexible strap 72 is sewn to the bottom of the trampoline.
Referring to fig. 10, the mount 72 may be disposed directly on top of the flexible rod 30. In the installation process, the bottom end 32 of the flexible rod 30 is inserted into the sleeve 26 of the supporting seat tube 20, then the strap 72 is passed through the through hole 723, the top 31 of the flexible rod 30 and the mounting member 72 are pushed to a predetermined position around the bouncing pad 10, the clamping member 73 is pulled out of the through hole 723, and the clamping member 73 is rotated to clamp the top 31 of the flexible rod 30 and the head 722 at the bottom around the bouncing pad 10, so that the purpose of installing the top 31 of the flexible rod 30 and the head 722 at the bottom around the bouncing pad 10 is achieved.
The mounting member 72 may be directly inserted into the strap 71.
