Abstract
The utility model discloses a pressing type pump head structure of a tire pump. A vent hole and a sleeving hole are formed in a pump head, a connecting piece, a middle screw sleeve, a middle shaft and a spring are arranged in the sleeving hole, a button is fixed to the rear end portion of the middle shaft, a changeover connecting mouth is arranged on the front end side of the connecting piece, first sealing rubber rings are assembled in the central hole of the connecting piece, and vent grooves are formed in the peripheral wall of the front end portion of the middle shaft. When the pressing type pump head structure is in a closed state, the first sealing rubber rings are in contact with the peripheral walls of the front end sides of the vent grooves of the middle shaft, and gas entering the vent grooves cannot enter a changeover air mouth. When the pressing type pump head structure is in a vented state, the vent grooves exactly face the first sealing rubber rings, the gas entering the vent grooves directly enters the changeover air mouth through the clearances between the vent grooves and the first sealing rubber rings, and a user can easily and accurately control air output by controlling the stroke of the button. Therefore, through the pressing type switch structure design, the pressing type pump head structure has the advantages of being convenient to use, and enabling the air output to be controlled accurately, easily and conveniently.
