The model utility content

The purpose of this utility model is to provide a kind of tyre inflating mouth, the mode of tyre inflating mouth employing spring card article both sides clamping is locked charging air inlet, the locking of spring card article is to realize by the up and down of movable sheath, the mode of relatively existing one-sided locking, the utility model is simple in structure, easy to operate, connect reliably, not easy to wear, long service life.

For achieving the above object by the following technical solutions:

A kind of tyre inflating mouth, comprise valve pocket and spool, valve core inside is provided with air flue, it is characterized in that: the top at described spool arranges outside thread, valve pocket inside is provided with the internal thread coordinated with the spool upper external thread, air outlet hole place at spool upper end air flue is provided with the air inlet thimble, be socketed with seal ring between air inlet thimble and valve sleeving inner wall, outer wall at valve pocket is provided with axial notch symmetrical more than two, have at every upper and lower two ends of axial notch the strip hole that penetrates the valve pocket outer wall, be provided with the spring card article in axial notch, the centre of spring card article is close to axial notch upper and lower two ends perk, be provided with the dop of bending to the inside at the two ends up and down of spring card article perk, dop is contained in the strip hole, also be socketed with movable sheath outside described valve pocket and spring card article, the height of movable sheath is less than the length of spring card article, movable sheath moves up and down dop that can the pressuring spring card article, dop is stretched out from inboard, strip hole.

Have spacing slotted eye on described movable sheath, on the position of the corresponding spacing slotted eye of valve pocket, be connected with limited screw.

The end of described dop is curved.

Bottom at described spool is provided with joint, and joint can directly be connected with flexible pipe.

Bottom at described spool is provided with the attaching nut, and the attaching nut is connected with flexible pipe by jointing.

Described air inlet thimble is flat, has the outgassing groove be communicated with air outlet hole in the bottom of air inlet thimble.

The utility model slides up and down by movable sheath, can realize inscribe and the ejection of spring card article upper end dop, when the valve pocket of charging air inlet is connected to cranked tire valve, seal ring plays seal action between cranked tire valve and spool and valve pocket, the air inlet thimble of spool upper end can back down the valve inside connection filling channel of cranked tire valve simultaneously, now movable sheath is upwards pushed away and make spring card article upper end dop inscribe, the dop end can be connected to the screw thread of the outer wall of cranked tire valve, make charging air inlet fixed tire valve, now open high-pressure air source and can be tire and inflated; Because the utility model is provided with spring card article symmetrical more than two, when charging air inlet and cranked tire valve are connected, the stressed situation that evenly not there will be local pressure wearing and tearing excessively to occur, the dop end arranges the arc coordinated with the cranked tire valve outer wall thread, and charging air inlet is fastening more reliable; The utility model adopts movable sheath to realize locking, and the up and down convenience of movable sheath, be not subject to the restriction of cranked tire valve surrounding space, uses convenient yet.
