[0024] The working principle of the present invention is as follows:

[0025] When the basketball stand is lowered for use, the height of the basketball hoop can be adjusted to meet the needs of users of different age groups. For example, the height for adults is 3.05 meters, and the height for teenagers is 2.75 meters, 2.6 meters, and 2.35 meters. Regardless of the height of the basketball hoop 14, the basketball hoop 14 must meet two position requirements at the same time: the basketball hoop at different heights must be located in the same vertical plane, and the basketball hoop 14 must remain horizontal.

[0026] When adjusting the height of the basketball hoop 14, the following two adjustment methods work together to ensure that the basketball hoop 14 is located in the specified vertical plane after the height adjustment. One adjustment method is: manually turning the crank of the hand-cranked self-locking winder 21 to reel in or unreel the wire rope 19. During the reeling or unreeling process of the wire rope 19, the main bracket 5, the fixed inner tube 6, the sliding outer tube 8 and the backboard 15 will flip up or down together, thereby adjusting the position of the backboard and then adjusting the position of the basketball hoop; the other adjustment method is: manually turning the handle of the hand-cranked self-locking winder 21 to reel in or unreel the wire rope 19. Or reverse the crank 13. During the rotation of the crank 13, the crank 13 drives the active sector gear 12 to rotate. The active sector gear 12 then drives the driven sector gear 10 to rotate, thereby synchronously driving the screw rod 9 to rotate forward or reverse. During the forward or reverse rotation of the screw rod 9, the screw rod 9 drives the sliding outer tube 8 to extend downward or retract upward relative to the fixed inner tube 6, thereby further adjusting the position of the backboard 15, and then adjusting the position of the basket ring 14 to ensure that the basket ring 14 is located in a specified vertical plane after the adjusted use height;

[0027] When the basketball hoop 14 is adjusted to the required height for use and the basketball hoop 14 is located in the specified vertical plane, the basketball hoop 14 often does not remain horizontal. The angle of the backboard 15 needs to be readjusted so that the backboard 15 is back in a vertical state perpendicular to the court so that the basketball hoop 14 remains horizontal. The specific adjustment process is as follows: first loosen the locking bolts 30, move the positioning pressure plate 28 and the U-shaped clamps 27 along the sliding outer tube 8, and drive the backboard 15 to rotate forward and upward or backward and downward around the lower pin 16 through the U-shaped pull rod 26 until the backboard 15 is in a vertical state. When the locking bolts 30 are tightened at the same time, the positioning pressure plate 28 and the U-shaped pull rod 26 can be relative to each other to clamp the sliding outer tube 8, thereby fixing the angle of the backboard 15, so that the backboard 15 is back in a vertical state perpendicular to the court, so that the basketball hoop 14 remains horizontal.

[0028] When the basketball hoop 14 needs to be folded up, the handle of the hand-cranked self-locking winder 21 is manually turned to reel in the wire rope 19. During the reeling process of the wire rope 19, the main bracket 5, the fixed inner tube 6, the sliding outer tube 8, the backboard 15 and the basketball hoop 14 will flip upward together until the hand-cranked self-locking winder 21 stops rotating after the basketball hoop 14 is folded up.

[0029] The advantages of the present invention are: (1) the manual suspended basketball stand adopts a purely mechanical structure without any electrical structure, and does not require electricity when in use. When the indoor venue is out of power, the basketball stand can still be used normally or folded up, and is easy to operate and use; (2) it is easy to disassemble and assemble, easy to maintain, and has high assembly efficiency; (3) the height of the basketball ring can be adjusted to meet the needs of users of different age groups, for example, the height for adults is 3.05 meters, and the height for teenagers is 2.75 meters, 2.6 meters, and 2.35 meters.

[0030] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention shall still fall within the scope of protection claimed by the present invention.
