A basketball net testing device has a mounting frame, a delivering mechanism, a shooting mechanism, a basketball hoop, a returning mechanism, and a controller. The delivering mechanism has multiple ball seats used for delivering basketballs. The shooting mechanism has a guiding disc and two speeding rollers. The ball seats deliver the basketballs to the guiding disc. The guiding disc guides each of the basketballs to drop between the speeding rollers. The speeding rollers are driven to rotate by a second motor assembly and increase momentum of the basketball. Thus, the basketball is shot into the basketball hoop to rub against a basketball net. Then the basketball drops into the returning mechanism and rolls back into one ball seat of the delivering mechanism in order to be used for testing durability of the basketball net again. |

1. A basketball net testing device comprising:
a mounting frame having
a receiving space formed in the mounting frame;a bottom panel transversely mounted at a bottom of the mounting frame;a side panel mounted at the bottom of the mounting frame and on the bottom panel, dividing the receiving space, and having a returning hole; anda top panel transversely mounted at a top of the mounting frame and having an output hole; a delivering mechanism mounted in the mounting frame and having
a mounting panel disposed in the mounting frame, mounted on and protruding up from the bottom panel, and having an upper end and a lower end;multiple pairs of elevating gears pivotally mounted on the mounting frame, and the elevating gears of each pair respectively corresponding in position to the upper end and the lower end of the mounting panel;multiple elevating chains respectively mounted around and engaging with the pairs of the elevating gears, and each of the elevating chains having an outer peripheral edge;multiple ball seats securely mounted separately on the outer peripheral edges of the elevating chains;a first motor assembly disposed beside the mounting panel, and connected to and selectively driving the elevating gears and the elevating chains;a pushing rod mounted on the top of the mounting frame and extending obliquely; a shooting mechanism mounted in the mounting frame and having
a guiding rail securely mounted on the top panel and having
an output end; andan input end corresponding in position to the pushing rod;two connecting panels separately mounted above the top panel, and oppositely disposed beside the output hole of the top panel, and each of the connecting panels having an upper edge;a guiding disc securely mounted on the upper edges of the connecting panels;two speeding rollers disposed apart from each other, mounted between and pivotally connected to the connecting panels, and a width defined between the speeding rollers corresponding to a width of the output hole of the top panel; anda second motor assembly mounted on the top panel and selectively driving the speeding rollers to rotate; a basketball hoop securely mounted on the mounting frame, and corresponding in position to and disposed below the output hole of the top panel; a returning mechanism mounted in the mounting frame, mounted through the side panel, and corresponding in position to the returning hole of the side panel, and the returning mechanism having
a ball input disposed below and corresponding in position to the basketball hoop; anda ball output corresponding in position to a moving path along which the ball seats move upward; and a controller mounted on the bottom panel of the mounting frame, and electrically connected to the first motor assembly and the second motor assembly. |
