The basketball hoop assembly is fixed in the base and has a light-transmitting backboard and a rim assembly fixed on the light-transmitting backboard. The light-transmitting backboard is inserted in the cavity and is adjacent to the LED module. The power-saving luminous basketball hoop set can be automatically lighted up by detecting vibration.

Abstract: An easily assembled inflator has a cylinder, a piston rod, a piston, an assembled seal cover and a sleeve. Because the assembled seal cover has at least two cover segments, the cover segments can be mounted around the piston rod by being connected together radially. Then the piston does not interfere with the cover segments and the sequence of the assembly of the piston and the assembled seal cover is not limited, as well. Thus, the assembly is more convenient and flexible. Besides, because the assembled seal cover has multiple cover segments, the whole assembled seal cover can bear more stress and has more room to be deformed. Then the assembled seal cover is not damaged and broken easily when pushed in to the cylinder. To sum up, the inflator as mentioned above is easy to be assembled and is not damaged easily during the assembly.

Thus, the functions of inflating, pressure measuring, depressurization and re-inflating can be accomplished by the barometer for eliminating the inconvenience of frequent installing and removing an inflation apparatus, a depressurization device and a pressure meter.

Abstract: A goal frame has multiple foldable joints and two upright posts, two bottom bars, an upper cross bar, and a lower cross bar connected with each other via the foldable joints. By pivoting the first and second connectors of each of the foldable joints to be perpendicular with each other, relative positions of the upright posts, the bottom bars, the upper cross bar, and the lower cross bar are fixed and the goal frame is unfolded. By pivoting the first and second connectors of each of the foldable joints to parallel with each other, the upright posts, the bottom bars, the upper cross bar, and the lower cross bar overlap and the goal frame is folded.

Abstract: 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.

Abstract: A basketball hoop has a stationary panel, a first pivoting seat, a rim assembly, a second pivoting seat and a torsion assembly. The torsion assembly has at least one torsion spring and a pivoting rod. The pivoting rod is mounted through the first pivoting seat and the second pivoting seat to pivotally mount the stationary panel around the rim assembly. The torsion springs offer a resilient force to resist the force of bending the rim assembly. With the torsion springs mounted around the pivoting rod, the basketball hoop in accordance with the present invention reduces the amount of the components. With the decrease of the amount of the components, the installation is easier and faster, and the cost is reduced therefore.

Abstract: A dual duty hand pump has two air channels, a hand grip, a piston rod, a piston, a deflating unit and an inflating unit. The hand grip and the piston are mounted on two ends of the piston rod. The deflating unit and the inflating unit are respectively mounted in the air channels and respectively have two check valves mounted therein in two opposite directions. When the hand grip is lifted and pressed down, air respectively flows in and flows out of the hand pump through the air channel. Accordingly, the hand pump provides a practical and convenient solution to integrate inflating and deflating functions as a whole for users to flexibly select from when the dual duty hand pump is in use.
