Abstract: An inflatable air nozzle connector comprises a clamping component, an airtight ring and a shell sleeve, the airtight ring is disposed in the clamping component; the shell sleeve is capable of slidably sleeving on an outer periphery of the clamping component and displacing between a pressing position and a releasing position. When the shell sleeve displaces downward to the pressing position, the clamping component is pressed, so that clamping jaws of the clamping component compress the airtight ring; when the shell sleeve displaces upward to the releasing position, the clamping jaws are not pressed, and the clamping jaws do not compress the airtight ring. When a user pushes or pulls the shell sleeve single-handedly, the inflatable air nozzle connector is capable of airtightly sleeving on an air nozzle of a tire, or separating from the air nozzle of the tire, making operation of inflating tire more convenient.

Abstract: An air inflation device includes an inflation unit having a chamber in which air can be compressed to generate a high pressure air, and an air outlet channel communicating with the chamber. A pressure gauge unit includes a pressure gauge, a shaft extending outwardly from the pressure gauge and inserted into the air outlet channel, and a check valve sleeved on the shaft and movable between an open state for allowing the high pressure air in the chamber to flow into the air outlet channel, and a closed state for preventing the high pressure air in the air outlet channel to flow back into the chamber. An air guide unit is connected to the inflation unit for guiding the high pressure air to flow out of the air outlet channel.

Abstract: An air pump includes a mouthpiece, an adjustment mechanism, and an air cylinder mechanism that includes a small-diameter cylinder permitted to move relative to the adjustment mechanism. When the small-diameter cylinder is moved away from the adjustment mechanism, air from external environment is sucked into a first space of the air cylinder mechanism. The adjustment mechanism is operable to switch between a singular pumping state, where air in the first space is released to the external environment when the small-diameter cylinder is moved toward the adjustment mechanism, and a dual pumping state, where the air in the first space is injected into the mouthpiece when the small-diameter cylinder is moved toward the adjustment mechanism.

Abstract: A kettlebell includes a base seat, a plurality of weight plates stacked on the base seat, and a lift seat separably disposed on the base seat. The base seat includes a base main body, an adjusting module mounted to the base main body for adjusting configuration of the lift seat and the weight plates, and a locking module mounted in the base main body. The locking module is operable to switch between a locking state in which the locking module engages the adjusting module such that the adjusting module is not operable, and an unlocking state in which the locking module disengages from the adjusting module such that the adjusting module is operable.

Abstract: An inflator includes a mouthpiece, an adjustment mechanism, and an air cylinder mechanism that includes a large-diameter cylinder permitted to move relative to the mouthpiece. When the large-diameter cylinder is moved away from the mouthpiece, air from external environment is sucked into a first space of the air cylinder mechanism. The adjustment mechanism is operable to switch between a pressure relief state, where air in the first space is released to the external environment when the large-diameter cylinder is moved toward the mouthpiece, and a sealed state, where the air in the first space is injected into the mouthpiece when the large-diameter cylinder is moved toward the mouthpiece.
