摘要： An air inflation device includes an inflation unit defining an interior space, a handgrip unit connected to the inflation unit, and a pressure measuring mechanism disposed in the handgrip unit and including a first tubular member defining a receiving space, and a second tubular member defining a flow guide channel that has an air inlet communicating with the interior space, and an air guide hole communicating with the receiving space. A measuring unit is disposed in the receiving space and has a free end pushed to move relative to the first tubular member by air entering the receiving space from the flow guide channel. An indicating unit indicates a position of the free end in the first tubular member.

摘要： A weight adjustable exercise device includes a base unit and a handle unit. Two magnetically attractive members are spacedly disposed on the base unit. Two weight sets are supported by the base unit, and respectively have a plurality of weights. The handle unit includes a handle shaft, two anti-rotation modules non-rotatably sleeved around two opposite end portions of the handle shaft and insertable downwardly in the base unit, two weight adjusting modules respectively mounted on the anti-rotation modules, and two indexing discs rotatably mounted on the weight adjusting modules. Each weight adjusting module has selector assemblies rotated with the handle shaft to selectively engage with or be disengaged from the corresponding weights. Each anti-rotation module has a magnet member removably engaged with the corresponding indexing disc and movable by a magnetically attractive force of the corresponding magnetically attractive member to be disengaged from the corresponding indexing disc.

摘要： 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.

摘要： A dumbbell assembly includes a base seat having two receiving areas, two weight units respectively received in the receiving areas, and a dumbbell. Each weight unit includes a plurality of weight blocks each having at least one engaging hole. The dumbbell includes a handle, and two weight adjustment modules each including an insertion base, and a plurality of engaging units each including a drive component mounted on the handle, and at least one insertion pin connected to the drive component. The handle is rotatable relative to the weight adjustment modules to drive each engaging unit to move between an engaging state and a disengaging state.

摘要： 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.

摘要： 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.

摘要： A pump head includes a casing unit, a tightening member and a control unit. The casing unit includes a main body and an abutment wall connected to the main body. The main body has an installation section. The tightening member is disposed in the installation section proximally to the abutment wall. The control unit includes a control valve, a resilient member and a control lever. The control valve is movably disposed in the installation section. The resilient member urges the control valve toward the abutment wall to clamp the tightening member between the control valve and the abutment wall. The control lever is connected to the main body and operable to move the control valve against the resilient member and away from the abutment wall.
