There is disclosed a balloon holder for holding a balloon having a tail and a tapered self-closing bladder. The balloon holder comprises a main body having a tail locking mechanism, an elongated member protruding from a bottom extremity of the main body, a support element configured to slide over the elongated member and be positioned on the main body, and a position adjustment mechanism for adjusting the position of the support element on the main body. In use, the tail of the balloon is secured to the main body by the tail locking mechanism and the support element is slid over the elongated member and positioned on the main body using the position adjustment mechanism so as to support the balloon in an upright position.

A detachable ball inflation and deflation device is disposed in a cavity of a ball. The device includes an air inflation unit, a non-return unit, and a reinforcement sleeve. By applying a force to press the air inflation unit repeatedly, the air outside the ball passes the non-return unit to enter the inside of the ball so as to inflate the ball, and the air filled into the ball won't deflate. The device has the function to deflate the ball in a quick way. When the air inflation unit is pulled out of a portion of the ball, the air inside the ball can be deflated quickly, so that the ball can be carried and stored conveniently.

An air compression pump includes a pump head and a pumping device fluidly connected with the pump head. The pumping device includes a cylinder fixed to the pump head. Further, a relief valve is fluidly connected with and received by the pump head. The relief valve defines a relief hole which is fluidly communicable with the first cylinder. The relief valve includes a valve body selectively closing the relief hole. The valve body is movable to an open position to relieve pressure in the air compression pump by allowing pressurized air to flow out of the air compression pump through the relief hole.

Embodiments of the present invention include a hand air pump handle assembly and a hand air pump, including a pressure gauge elastically attached thereto. The hand air pump handle assembly comprises a handle shell that defines an accommodating space for placement of the pressure gauge. The accommodating space is provided with an air vent for connecting the accommodating space to an inflatable body, such as an inflatable mattress. The pressure gauge measures an internal air pressure for the inflatable body via the air vent and is connected to the handle shell with an elastic connector. The elastic connector can elastically deform to prevent the pressure gauge from being damaged or broken under external forces such as an impact.

An air valve connecting device or attachment includes a mouth engaged in a housing and having a compartment for engaging with either a US or French inflation valve, a barrel engaged into the housing and engaged onto the mouth, an actuator slidably engaged in the housing and engageable with the barrel, and a cam member is engageable with the actuator for selectively forcing the actuator and the barrel to compress the mouth to grasp either of the inflation valves to the housing, a tube is slidably engaged in the actuator and extendible into the mouth, and a catch is slidably engaged in the actuator and engageable into the actuator for selectively engaging with and for retaining the tube to the actuator.

A pump that includes a body having a base and a top portion, wherein the base is configured to be anchored to the ground and the top portion is detachably connected to an upper plate in the body. The pump includes a handle assembly including a piston rod, handle bar, and cap that are detachably connected to each other by a fastener. The pump includes a tube positioned in the body. The tube slidably receives the piston rod and is connected to an air line. A hose is connected to the air line and extends from the body. The hose has a head configured to engage the nozzle of a tire. When the piston rod is moved downward within the tube, air is displaced from the tube and through the air line to the hose such that the head dispenses air.

A hand pump includes a receptacle extended upwardly from a base, a housing attached to the base and having a port connected to a pressure gauge, a hose coupled to the housing and having a nozzle for inflating tires or objects, a sleeve slidably engaged onto the receptacle, and a check valve engaged in the receptacle for controlling the pressurized air to flow only from the sleeve into the receptacle and for preventing the pressurized air from flowing backward from the receptacle into the sleeve in order to generate the pressurized air in the receptacle, and for allowing the receptacle to store the pressurized air when required. A control valve device controls the pressurized air to flow out of the housing.
