Description

A basketball hoop that is easy to adjust in height Technical Field

[0001] This invention relates to the field of sports equipment technology, and in particular to a basketball hoop that is easy to raise and lower. Background Technology

[0002] Basketball hoops are essential equipment for basketball courts. Basketball equipment includes backboards and backboard supports, which are installed at the center of each end of the court. Types of backboards used include hydraulic, mobile, fixed, suspended, "seagull" type, and "cannon" type, among others.

[0003] Chinese Patent Publication No. CN104722049B discloses a basketball hoop, comprising a base, a first column assembly, a second column assembly, a support frame, a buffer cylinder rod, a backboard, and a basket. When the basket height needs adjustment, the height of the first and second telescopic tubes relative to the base is adjusted using a first bolt and a second bolt, respectively. Since the two ends of the support frame are connected to the first and second telescopic tubes, the tilt angle of the support frame relative to the base changes when the height of the first or second telescopic tube changes, thereby affecting the height of the basket. The buffer cylinder rod effectively stabilizes the support frame during movement. When the basket size needs adjustment, the basket is simply adjusted to a suitable height, and then the outer diameter of the basket is adjusted. This basketball hoop allows for adjustment of both the basket height and size, has a wider range of applications, and is suitable for the exercise needs of people of different ages.

[0004] The existing basketball hoop height adjustment is quite complicated, and while adjusting the height, there is also a certain horizontal position, which requires the overall hoop position to be readjusted. In addition, there are many adjustment and control devices, which are located on the top of the base. Basketball is a very intense sport, and players are prone to running off the court when dunking or making a layup. The exposed adjustment mechanism makes the device pose a significant safety risk.

[0032] Example 1

[0033] As shown in Figure 1, a basketball hoop that is easy to raise and lower includes a basketball hoop frame 1, a support rod 3, and a base 4. The support rod 3 is fixedly connected to the upper end face of the base 4. The basketball hoop frame 1 is located at the end of the support rod 3 away from the base 4. The characteristic feature is that the end of the support rod 3 away from the base 4 is provided with a height adjustment mechanism 2 for vertically adjusting the height of the basketball hoop frame 1. The upper end face of the base 4 is rotatably provided with a protective baffle 5. The end of the protective baffle 5 away from the base 4 is rotatably connected with an adjusting ring 6. The adjusting ring 6 is slidably sleeved on the outer end face of the support rod 3.

[0034] Furthermore, the surface of the protective baffle 5 is made of a flexible material.

[0035] In use, the height adjustment mechanism 2 allows for easy adjustment of the vertical height of the basketball hoop frame 1, thereby improving the adaptability of the basketball hoop to different venues or events. Furthermore, the protective baffle 5, located below the basketball hoop frame 1, effectively prevents injuries caused by collisions with the hoop during exercise. The protective baffle 5 is also inclined and has a flexible material on its surface, which enhances the protection for players.

[0036] Example 2

[0037] Based on Embodiment 1, as shown in Figures 1-2, the height adjustment mechanism 2 includes a sliding plate 7, an extension plate 8, a driving device 9, and a limiting plate 10. The sliding plate 7 is fixedly connected to the back of the basketball hoop frame 1. The driving device 9 is fixedly connected to the end of the support rod 3 away from the base 4. The driving device 9 is used to drive the sliding plate 7 to move vertically. The two sides of the driving device 9 are fixedly connected to the extension plate 8 extending to the edge of the basketball hoop frame 1. The limiting plate 10 is fixedly connected to the end of the extension plate 8 away from the driving device 9. The limiting plate 10 is in contact with the edge of the surface of the basketball hoop frame 1.

[0038] As shown in Figures 1-4, a drive rod 12 is rotatably connected inside the support rod 3. One end of the drive rod 12 is provided with a first bevel gear 13. A driven bevel gear 11 is rotatably connected inside the drive device 9. A toothed rod 14 is fixedly connected to the middle of the driven bevel gear 11. The sliding plate 7 is provided with tooth grooves that are adapted to the toothed rod 14.

[0039] In use, the extension plate 8 and the limiting plate 10 extend to fix and limit the basketball hoop frame 1, preventing the basketball hoop frame 1 from moving laterally. This allows the sliding plate 7 to maintain its meshing effect with the gear 14. The rotation of the drive rod 12 drives the first bevel gear 13 to rotate, which in turn drives the driven bevel gear 11 to rotate. This causes the gear 14 to rotate and drive the sliding plate 7 to move up and down reciprocally, thereby adjusting the vertical height of the basketball hoop frame 1. The cooperation between the limiting plate 10 and the drive device 9 allows the device to stably control the height of the basketball hoop frame 1.

[0040] As shown in Figures 1-3 and 5-6, a spiral groove 15 is provided on the side end face of the drive rod 12, a limiting protrusion 30 adapted to the spiral groove 15 is provided on the inner wall of the adjusting ring 6, and a vertical sliding groove adapted to the limiting protrusion 30 is provided on the surface of the support rod 3.

[0041] Furthermore, the limiting protrusion 30 penetrates the vertical groove on the surface of the support rod 3 and is adapted to the spiral groove 15 on the surface of the drive rod 12.

[0042] In use, as the drive rod 12 rotates to adjust the height of the basketball hoop frame 1, the spiral groove 15 rotates synchronously with the drive rod 12. Under the action of the limiting protrusion 30, the drive adjustment ring 6 moves up and down synchronously. When the height of the basketball hoop frame 1 increases, the adjustment ring 6 also increases synchronously, thereby increasing the vertical tilt angle of the protective baffle 5, increasing the protective area, and thus improving the buffer protection effect for athletes. This allows the device to improve the protective effect synchronously as the height of the basketball hoop frame 1 increases.

[0043] As shown in Figures 1-3 and 7, the protective baffle 5 includes a first movable baffle 19 and a second movable plate 21. The second movable plate 21 is rotatably connected to the base 4, and the first movable baffle 19 is rotatably connected to the adjusting ring 6. The first movable baffle 19 and the second movable plate 21 are connected to each other by a connecting rod 22. The side end faces of the connecting rod 22 and the second movable plate 21 are provided with fixing pin holes 17. The second movable plate 21 is provided with a pin 18 that matches the fixing pin holes 17.

[0044] In use, when adjusting the height of the basketball hoop frame 1, the protective baffle 5 is disassembled into a first movable baffle 19 and a second movable plate 21. This allows the first movable baffle 19 and the second movable plate 21 to stretch each other while the angle of the protective baffle 5 is adjusted, thereby increasing their buffer area. At the same time, the connecting rod 22 and the second movable plate 21 are fixed by inserting the pin 18 into the fixing pin hole 17, thus fixing and locking the first movable baffle 19 and the second movable plate 21. After the first movable baffle 19 and the second movable plate 21 are locked, the position of the adjusting ring 6 can be fixed, thereby preventing the rotation of the drive rod 12. The device locks the protective baffle 5 by connecting the fixing pin hole 17 and the pin 18, thereby improving the stability of the device structure.

[0045] As shown in Figures 1-3 and 7-10, a drive gear 29 is rotatably connected inside the base 4. A drive disk 28 is provided on the upper end of the drive gear 29. A second bevel gear 16 is provided at the end of the drive rod 12 that is away from the first bevel gear 13. The second bevel gear 16 meshes with the drive gear 29.

[0046] Furthermore, the drive disc 28 and the drive gear 29 are assembled together, which makes the drive disc 28 easy to remove. This makes the device easy to disassemble and avoids safety hazards caused by unauthorized personnel's misoperation. The drive disc 28 can be removed after the device is adjusted.

[0047] In use, a drive disc 28 is provided to facilitate the adjustment of the device. When the height of the device needs to be adjusted, the drive rod 12 and the protective baffle 5 are unlocked by pulling out the pin 18. The drive disc 28 is rotated to drive the drive gear 29 to rotate, which in turn drives the drive rod 12 to rotate. This causes the drive rod 12 to drive the sliding plate 7 and the adjusting ring 6 to move up and down, thereby adjusting the height of the basketball hoop frame 1 and the tilt angle of the protective baffle 5.

[0048] Example 3

[0049] Based on Embodiments 1 and 2, as shown in Figures 1-3 and 7-10, the base 4 has an interconnected movable cavity 26 and a negative pressure cavity 25 inside, and an adsorption plate 23 is provided at the bottom of the base 4. The adsorption plate 23 is connected to the negative pressure cavity 25, and a sealing plate 24 is elastically connected inside the movable cavity 26.

[0050] In use, the suction plate 23 at the bottom of the base 4 increases the suction force between the base 4 and the bottom surface, thereby improving the stability of the basketball hoop. At the same time, a sealing plate 24 is slidably connected inside the active cavity 26. As the sealing plate 24 moves, the negative pressure inside the negative pressure cavity 25 can be controlled, thereby controlling the suction effect of the suction plate 23.

[0051] As shown in Figures 1-3 and 7-10, the base 4 has a baffle groove 27, and the side end face of the second movable plate 21 is provided with a rotating rod 20. The second movable plate 21 is rotatably connected to the inside of the baffle groove 27 through the rotating rod 20. The side end face of the rotating rod 20 is provided with a driving protrusion 31. The driving protrusion 31 extends perpendicularly to the surface of the protective baffle 5 and extends into the interior of the movable cavity 26 to fit against the surface of the sealing plate 24.

[0052] Furthermore, the adsorption plate 23 can be made of elastic materials such as rubber to improve its adhesion to the ground.

[0053] During use, as the height of the basketball hoop frame 1 increases, the center of gravity of the basketball hoop also increases synchronously. At the same time as the basketball hoop frame 1 increases, the protective baffle 5 will also increase its rotation angle. As the protective baffle 5 rotates, the rotating rod 20 will drive the driving protrusion 31 to rotate synchronously. As the driving protrusion 31 rotates, the amount of pressure of the driving protrusion 31 on the sealing plate 24 decreases. Under the action of elasticity, the sealing plate 24 moves upward inside the active cavity 26, thereby increasing the negative pressure inside the negative pressure cavity 25, which in turn improves the adsorption effect of the adsorption plate 23. As the height of the basketball hoop frame 1 increases, the device can automatically improve the stability of the base 4, avoiding safety hazards such as the center of gravity rising due to the increase of the basketball hoop frame 1, and improving the safety of the device.

[0054] Working principle: The height adjustment mechanism 2 allows for easy adjustment of the vertical height of the basketball hoop frame 1, thereby improving the adaptability of the basketball hoop to different venues or events. A protective baffle 5, located below the basketball hoop frame 1, effectively prevents injury from collisions during play. The protective baffle 5 is angled and its surface is made of flexible material to enhance player protection. The extension plate 8 and limiting plate 10 extend to fix and limit the basketball hoop frame 1, preventing lateral movement and ensuring the sliding plate 7 remains engaged with the gear 14. The rotation of the drive rod 12 drives the first bevel gear 13, which in turn drives the driven bevel gear 11, causing the gear 14 to rotate and drive the rack. The sliding plate 7 moves up and down reciprocally, thereby adjusting the vertical height of the basketball hoop frame 1. The cooperation between the limiting plate 10 and the driving device 9 allows the device to stably control the height of the basketball hoop frame 1. As the driving rod 12 rotates to adjust the height of the basketball hoop frame 1, the spiral groove 15 rotates synchronously with the driving rod 12. Under the action of the limiting protrusion 30, the driving adjustment ring 6 moves up and down synchronously. When the height of the basketball hoop frame 1 increases, the adjustment ring 6 also increases synchronously, thereby increasing the vertical angle of the protective baffle 5, increasing the protective area, and thus improving the cushioning and protection effect for athletes. This allows the device to synchronously improve the protective effect as the height of the basketball hoop frame 1 increases. During the height adjustment of the basketball hoop frame 1, the protective baffle 5 is disassembled into... The first movable baffle 19 and the second movable plate 21 allow the protective baffle 5 to be adjusted at an angle while the first movable baffle 19 and the second movable plate 21 stretch against each other, increasing their buffer area. Simultaneously, the connecting rod 22 and the second movable plate 21 are fixed by inserting the pin 18 into the fixing pin hole 17, thus fixing and locking the first movable baffle 19 and the second movable plate 21. After the first movable baffle 19 and the second movable plate 21 are locked, the position of the adjusting ring 6 is fixed, preventing the rotation of the drive rod 12. The device, through the pin connection between the fixing pin hole 17 and the pin 18, not only fixes and locks the protective baffle 5 but also locks the drive rod 12, improving the stability of the device structure. For easy adjustment of the device, a drive disc 28 is provided. When the height of the device needs to be adjusted, the locking of the drive rod 12 and the protective baffle 5 is released by pulling out the pin 18. Rotating the drive disc 28 drives the drive gear 29 to rotate, which in turn drives the drive rod 12 to rotate. This causes the drive rod 12 to move the sliding plate 7 and the adjusting ring 6 up and down, thereby adjusting the height of the basketball hoop frame 1 and the tilt angle of the protective baffle 5. The suction plate 23 at the bottom of the base 4 increases the suction force between the base 4 and the bottom surface, thus improving the stability of the basketball hoop. Simultaneously, a sealing plate 24 is slidably connected inside the movable cavity 26. As the sealing plate 24 moves, the negative pressure inside the negative pressure cavity 25 can be controlled, thereby controlling the suction effect of the suction plate 23. As the height of the basketball hoop frame 1 increases, the center of gravity of the basketball hoop also increases synchronously.As the basketball hoop frame 1 is raised, the protective baffle 5 also increases its rotation angle. Simultaneously, the rotating rod 20 drives the driving protrusion 31 to rotate synchronously. This rotation of the driving protrusion 31 reduces the pressure exerted by the driving protrusion 31 on the sealing plate 24. Under the action of elasticity, the sealing plate 24 moves upward within the movable cavity 26, thereby increasing the negative pressure inside the negative pressure cavity 25. This, in turn, improves the adsorption effect of the adsorption plate 23. Consequently, the device can autonomously increase the stability of the base 4 as the height of the basketball hoop frame 1 increases, avoiding safety hazards such as a raised center of gravity caused by raising the basketball hoop frame 1, and improving the safety of the device.
