Description

Technical Field

[0001] The present invention relates to the technical field of backboard structures, in particular to a backboard structure for a trampoline. Background Art

[0002] Traditional trampoline entertainment facilities, especially those incorporating basketball elements, typically simply place a standard basketball hoop near or above the trampoline area. This creates a basketball hoop with a shooting function, enhancing the fun of trampoline play. While trampolines can be deployed outdoors and in public areas for a variety of entertainment, different height groups have different requirements for the backboard height, making it difficult to meet the needs of different age groups.

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Figures 1-6 A trampoline backboard structure includes a trampoline body, wherein the trampoline body includes an annular frame 11, a jumping cloth is arranged in the annular frame 11, and a plurality of vertical protective tubes are installed upwardly from the annular frame 11 for fixing the trampoline enclosure.

[0021] In this embodiment, a shooting unit is provided on the first protective tube 1 and the second protective tube 2. The shooting unit includes a basketball board 4, a basket 5, and several mounting rods and a mesh 17 for receiving rebounded basketballs. Specifically, the basket 5 is provided on the basketball board 4. Two groups of lifting rods 3 are provided at the bottom of the basketball board 4. The lifting rods 3 are provided with threads. The lifting rods 3 are matched and installed in the first protective tube 1 and the second protective tube 2. When the first fireproof tube and the second protective tube 2 rotate synchronously, the synchronous lifting and lowering of the basketball board 4 can be controlled.

[0022] A serving unit is installed below the basketball board 4. The serving device includes an angle-adjustable ball guide tube 6. The ball guide tube 6 has an inlet 7 for receiving the basketball and an outlet 8 for launching the basketball. The rear bottom support of the ball guide tube 6 is arranged on an adjustable height adjustment rod 9. A sleeve 10 is arranged on the outside of the adjustment rod 9. The two groups are connected by a thread, and the direction of the thread is opposite to that on the lifting rod 3. That is, when the basketball board 4 is rotated in the same direction, the adjustment rod 9 drives the rear of the ball guide tube 6 to descend while the basketball board 4 is raised, thereby increasing its ball-discharging angle.

[0023] The front end of the ball guide tube 6 is connected to the mounting groove in the ball guide tube 6 through an axial rotation. When the sleeve 10 is rotated, the adjusting rod 9 is pressed by the ball guide tube 6 and cannot be rotated, thereby realizing the up and down movement of the screw.

[0024] An adjustment unit is provided at the bottom of the annular frame 11. The adjustment unit includes a first pulley 12 connected to the sleeve 10 and a second pulley 13 connected to the lifting tube. Multiple second pulleys 13 connected to the lifting rod 3 are linked by an annular belt 15. Specifically, the second pulleys 13 are connected by a belt 15. A third pulley 14 is provided below each second pulley 13. The first and third pulleys 12, 14 are connected by a belt 15, and the diameter of the third pulley 14 is smaller than that of the first pulley 12. Furthermore, for every rotation of the first pulley 12, the third pulley 14 can rotate multiple times. This combination of large and small pulleys forms a deceleration and lifting mechanism, adapting the ratio of the height difference between the basketball board 4 and the ball guide tube 6.

[0025] Mounting rods are also installed obliquely on the first protective tube 1 and the second protective tube 2 supporting the basketball board 4. The mounting rods are fixed to the protective tubes via special mounting parts, and a box body 16 is fixed between adjacent mounting parts. The mounting rods themselves are designed as a telescopic structure, which includes a rod sleeve 19 and a rod body 18 that can slide inside it.

[0026] A mesh 17 is provided on the mounting rod to receive the basketball that hits the basketball board 4, so as to prevent the basketball from rebounding quickly on the jumping cloth, thereby avoiding the risk of the user coming into contact with the basketball on the flexible jumping cloth. Furthermore, one end of the mesh 17 is fixedly connected to the top of the rod body 18, and the other end is wound and stored inside the box body 16; the box body 16 is equipped with a storage unit, which includes a winding shaft 20, a turbine 21 and a worm 22 meshed with it. One end of the worm 22 is fixedly connected to the winding shaft 20. When the worm 22 is rotated, the turbine 21 on one side thereof is driven to rotate, and the winding shaft 20 is rotated. The other end of 0 is connected to the coil spring 23 that provides the rewinding force; the rod body 18 is connected to the winding shaft 20 through the pull rope 24. When the rod body 18 is pulled outward, it will drive the winding shaft 20 to rotate, overcome the torsion of the coil spring 23, and release the mesh 17; when the mesh 17 needs to be put away, the worm 22 is turned to drive the turbine 21 and the winding shaft 20 to rotate. The worm gear 22 has a self-locking feature and will continuously keep the mesh 17 in use in a tensioned state, that is, when the height of the basketball board 4 is readjusted, the mesh 17 will not be too loose to trap the basketball in the mesh 17. The tensioned mesh 17 can transport the basketball along its direction.

[0027] In order to adjust the rod body 18 in the future, a protruding positioning rod 25 is fixed on the basketball board 4. The positioning rod 25 is connected to the rod body 18 of the mounting rod. The positioning rod 25 and the rod body 18 are rotationally connected. When the positioning rod 25 is moved, the rod body 18 will be directly driven to slide in the rod sleeve 19.

[0028] In order to facilitate the rapid entry of the basketball into the serving unit after being collected, a ball guiding frame 26 is further provided on the periphery of the ball guiding tube 6. The ball guiding frame 26 includes a vertical column 27, a horizontal plate 28 connecting the vertical column 27, and a ball guiding rod 30 connected to the mounting part. The ball guiding rod 30 is located on both sides of the ball guiding frame 29 of the horizontal plate 28. A guide mesh 17 for guiding the basketball to slide toward the entrance 7 of the ball guiding tube 6 is stretched between the ball guiding rods 30 on both sides. A flexible mesh bag 31 is also connected between the guide frame and the entrance 7 of the ball guiding tube 6; thereby enabling the basketball to enter the ball guiding tube 6.

[0029] Furthermore, rollers for launching basketballs are provided at the outlet 8 of the ball guide tube 6, including a pair of first rollers 32 and second rollers 33 arranged up and down. The two rollers are driven by a motor to rotate in opposite directions. When the basketball enters the bite area between the two rollers, it will be ejected by friction and shot toward the trampoline area. In order to ensure that the basketball can reliably enter the roller launching area, a booster is also installed inside the ball guide tube 6. The booster is a rotatable V-shaped folding plate, consisting of a first folding plate 34 and a second folding plate 35. The first folding plate 34 is connected to the inner wall of the ball guide tube 6 by a spring 36. When the basketball rolls in and presses on the first folding plate 34, it will overcome the resistance of the spring 36 and cause the entire folding plate to rotate. At this time, the second folding plate 35 will push the basketball toward the roller at the outlet 8, completing the boosting process.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
