The first mounting unit includes a first casing and an end cap, and the reception end includes a valve mouth and a core tube received therein. The second mounting unit includes inner threads that are connected with the connection portion. A groove is defined in the second mounting unit and an O-ring is engaged with the groove. The first and second mounting units can be connected with an American style tire valve and a French style tire valve, respectively. The first and second mounting units each have outer threads with the same diameter so as to be connected with a tire pump.

A portable air pump includes a tubular body, a barrel, a piston mechanism, a head, and a dispensing head. The tubular body has an upper cover having air inlet holes and a sealed bottom cover. The barrel has an air passage running through it along its axis direction. The piston has a center hole and a through hole, and a check valve is in positioned between the second end of the barrel and the bottom end of the piston. As the tubular body is moved in relation to the barrel away from the head, air flows into the tubular body through the air inlet holes and to the bottom of the tubular body through the through hole. Air is prevented from flowing out through the center hole of the piston by use of a check valve disc. As the tubular body is moved in relation to the barrel towards the head, air in the bottom of tubular body flows into the air passage of the barrel through the center hole, and out through the head and the dispensing head.

Portable air pump

A dispensing head for an air pump includes a sleeve connected to the air pump and a chamber is defined in an end of the sleeve. The end having the chamber of the sleeve is received in a housing and a mount piece is securely received in the housing. A first seal ring is mounted to the mount piece and in contact with an inner periphery of the chamber. The mount piece includes a plurality of inner threads defined axially in a central passage in the mount piece, so that the threaded section of a French valve is threadedly connected to the inner threads. A second groove is defined in the mount piece and a second seal ring is engaged with the second groove. The second seal ring is mounted to a neck of the French valve.

Pump connector for Presta valve is disclosed in which one end of a pump connector valve seal is formed with a hollow chamber, and is disposed inside a space of a cap having a channel. The hollow chamber is assembled with a valve seal insert which includes a through hole. The second end of the through hole is formed with an inner edge corresponding to the shape of the shoulder section of the Presta valve. An end cap is assembled with the cap for preventing the pump connector valve seal from separating from the cap. Accordingly, the Presta valve can be screwed together with a first internal thread of the cap, and at the same time the shoulder section of the Presta valve is tightly fitted to the inner edge of the valve seal insert for direct inflation.

A universal air pump includes a pump; a head mounted to the pump and having a central hole and an air inlet at a side wall thereof; a cylindrical block pivotably fitted in the central hole of the head and having a central chamber, an annular channel on an outer surface thereof, which faces to the air inlet of the head, and at least one air hole defined through an underside of the annular channel and communicating with the central chamber; a fixing seat having a stub tube engaged with the central chamber of the cylindrical block, and an axially-extended through hole communicating with the central chamber; and an air delivery tube mounted to the fixing seat and communicating with the axially-extended through hole. Thus the air delivery tube can rotate relative to the head so as to allow the air pump to be operated at any angle.

An air pump nozzle includes a housing with an inflation hole. An inner space of the housing lodges a block assembly seat having a compartment at an end. The compartment lodges a block member having an insertion hole. A needle tube with an air outlet is inserted through the insertion hole and is retained to avoid being disaffiliated from the block member. The design of separate needle tube and block assembly seat can simplify the manufacturing procedure and product assembly, as well as reduce the manufacturing cost.

Air pump nozzle

An air nozzle includes a hollow casing, a plug received in the chamber and having a channel defined through the plug, a central tube movably received inside the channel of the plug and having an outer threading formed on an outer periphery thereof, a nozzle rotatably received inside the chamber and having a nose out of the top open end of the hollow casing and a compartment to receive therein the central tube and the plug and a cap to secure the nozzle, the central tube and the plug inside the hollow casing such that movement of the central tube allows the air nozzle to adapt to various positions of a central pin of a second air nozzle in an object for inflation.

A hand-operated inflator with dual cylinder is provided. Once the cylinders are pulled out on two sides of the central block to form a line axially, and a clamp plate at mid point in between the two cylinders is turned to the transversal position to lock the cylinders in place, the inflator is set for refilling operation. The two cylinders can be folded back when the clamp plate is released, making it easy for carrying and storage with the length reduced by half. The inflator is able to inflate an object with faster rate as compared with the conventional inflators with only one air cylinder. Moreover, the central block can be attached with a pressure meter. If the measured air pressure inside the object gets excessively high, air can be safely released through an over pressure valve.

Hand-operated inflator

Disclosed is a pressure gauge including a body forming an inlet, an outlet, and a shunt hole. A pressure meter is provided to the shunt hole. An inlet duct in connection with an inflation device is provided to the inlet. A check valve is arranged in the inlet duct. An outlet duct is connected to the outlet and is prepared with an inflation mouth for coupling with an intake nozzle of an object to be inflated. When an inflation device is operated to charge air into an object for inflation through the inlet duct, the body, and the outlet duct, a pressure measuring process can be performed concurrently.

Pressure gauge

An inflator includes a hollow handgrip and an air cylinder having a shaft. One end of the shaft is connected with a piston in the cylinder and the other end of the shaft is provided with a stud extending out of the cylinder. A bottom wall and an opening are arranged respectively at opposite ends of the handgrip. A tapped hole is formed in the bottom wall for locking the stud. Through the opening, the cylinder may be stored in the handgrip to lessen the volume of the inflator. When using the inflator, a user draws the cylinder out of the handgrip and lock the stud to the tapped hole through the bottom end of the handgrip to thereby extend the shaft. Air is pumped out through an outlet of the cylinder by reciprocal axial motion of the shaft.
