Abstract
A pumping device includes a main body having a passage defined therein and communicated with an air source. A retainer is slidably received in the main body and includes a chamber communicated with the passage of the main body. A nozzle is received in the chamber of the retainer and includes a nozzle passage communicated with the chamber. A plastic nozzle head is securely mounted in the main body and includes a valve chamber defined therein and communicated with the nozzle passage. A lever is provided for switching the retainer between a first inoperative position and a second operative position in which when the retainer is switched to the second operative position, the retainer exerts an inward force upon an outer periphery of the plastic nozzle head.
Claims16
A pumping device comprising:
- a main body having a passage defined therein and adapted to be communicated with an air source, the main body further including a compartment defined therein and communicated with the passage,
- a retainer slidably received in the compartment of the main body, the retainer including a chamber defined therein and communicated with the passage of the main body, the retainer further including a positioning member pivotally mounted therein,
- a nozzle received in the chamber of the retainer and including a nozzle passage communicated with the chamber,
- a nozzle head securely mounted in the compartment of the main body, the nozzle head including a valve chamber communicated with the nozzle passage and adapted to receive a tire valve, and
- means for switching the retainer between a first inoperative position and a second operative position,
- whereby when the retainer is switched to the second operative position, the nozzle is moved to engage with the tire valve inserted into the valve chamber, and the positioning member is pivoted into the chamber of the retainer to stop further inward movement of the tire valve.
A pumping device comprising:
- a main body having a passage defined therein and adapted to be communicated with an air source, the main body further including a compartment defined therein and communicated with the passage,
- a lever pivotally connected to the main body,
- a retainer slidably received in the compartment of the main body and including a first end attached to and actuatable by the lever and thus movable between a first inoperative position and a second operative position, the retainer including a chamber defined therein and communicated with the passage of the main body, the retainer further including a positioning member pivotally mounted therein,
- a nozzle received in the chamber of the retainer and including a nozzle passage communicated with the chamber,
- a nozzle head securely mounted in the compartment of the main body and including a valve chamber communicated with the nozzle passage and adapted to receive a tire valve,
- whereby when the lever is pivoted to urge the retainer to move to the second operative position, the nozzle is moved to engage with the tire valve inserted into the valve chamber, and the positioning member is pivoted into the chamber of the retainer to stop further inward movement of a valve inserted into the nozzle head.
