The first embodiment is as follows: the utility model provides a conversion inflating mouth, refers to fig. 1, includes outlet duct 1 and connects in the locking pipe 2 of 1 one end of outlet duct, 1 inside sliding connection of outlet duct has core pipe 3, core pipe 3 with 1 coaxial setting of outlet duct, core pipe 3 with be connected with spring 11 between the outlet duct 1, locking pipe 2 keeps away from the one end inner wall of outlet duct 1 by outer to interior be equipped with in proper order with American inflating mouth screw-thread fit's first internal thread 21 and with French inflating mouth screw-thread fit's second internal thread 22, outlet duct 1 with be connected with the positioning element 4 that is used for fixing a position core pipe 3's core mouth protrusion in first internal thread 21 department, protrusion in second internal thread 22 department between locking pipe 2, and under the spring 11 natural state, the core mouth protrusion of core pipe 3 is in first internal thread 21 department.

When the American-type air faucet is inflated by the conversion inflating nozzle, the locking pipe 2 is connected to the external thread at the end part of the American-type air faucet through the first internal thread 21 in a threaded manner, at the moment, the spring 11 is in a natural state, the core nozzle of the core pipe 3 protrudes out of the first internal thread 21 and is aligned with the American-type air faucet, and then the positioning assembly 4 is used for fixing the aligned positions of the core nozzle of the core pipe 3 and the American-type air faucet so that the core nozzle cannot move when the American-type air faucet is inflated;

when the conversion inflating nozzle inflates the French air nozzle, the locking pipe 2 is connected to the external thread at the end part of the French air nozzle through the second internal thread 22 in a threaded mode, the spring 11 is in a compressed state at the moment, the core nozzle of the core pipe 3 protrudes out of the second internal thread 22 and is aligned with the French air nozzle, and then the positioning assembly 4 is used for fixing the aligned positions of the core nozzle of the core pipe 3 and the French air nozzle so that the core nozzle cannot move when the French air nozzle is inflated;

therefore, the purpose that a user can flexibly convert the inflating nozzle conveniently and can adapt to the American and French air nozzles for inflating is achieved, and the converting inflating nozzle is universal and does not need to replace other inflating nozzles.

The positioning component 4 comprises a conversion sleeve 41 sleeved between the air outlet pipe 1 and the locking pipe 2; the gas-liquid separation device further comprises a ball 42 abutted between the outer wall of the core tube 3 and the inner wall of the conversion sleeve 41, wherein the ball 42 is positioned between the gas outlet tube 1 and the locking tube 2, a positioning groove 411 for the ball 42 to move up and down is formed in the inner wall of the conversion sleeve 41, a first protrusion 31 is formed in the outer wall of the core tube 3, and the height of the first protrusion 31 is equal to the depth of the positioning groove 411; when the core mouth of the core tube 3 protrudes from the first internal thread 21, the ball 42 abuts against one side of the first protrusion 31 away from the locking tube 2, and when the core mouth of the core tube 3 protrudes from the second internal thread 22, the ball 42 abuts against one side of the first protrusion 31 close to the locking tube 2.

When the core nozzle of the positioning core tube 3 protrudes out of the first internal thread 21, the ball 42 abuts against one side of the first protrusion 31 away from the locking tube 2, the conversion sleeve 41 is rotated, so that the vertical positions of the positioning groove 411 and the ball 42 are staggered, the ball 42 abuts between the inner wall of the conversion sleeve 41 and the outer wall of the core tube 3, at the moment, the spring 11 is in a natural state, the first protrusion 31 limits the core tube 3 to move towards the inside of the air outlet tube 1, and therefore the alignment stability of the core tube 3 and the American-style air nozzle is guaranteed, and positioning is achieved;

when the core nozzle of location core pipe 3 protrudes in second internal thread 22, change-over sleeve 41 is rotated, make the constant head tank 411 be located the upper and lower position of ball 42, so that ball 42 is to the inside activity of constant head tank 411, later french air cock butt core nozzle compression spring 11, make ball 42 slide first arch 31, and the butt is close to one side of locking pipe 2 in first arch 31, change-over sleeve 41 is rotated again at last, make constant head tank 411 and ball 42's upper and lower position stagger, thereby with ball 42 butt between the inner wall of change-over sleeve 41 and the outer wall of core pipe 3, spring 11 is in compression state this moment, first arch 31 restricts core pipe 3 and moves to outlet pipe 1 outside, thereby guaranteed the stability that core pipe 3 and french air cock align, realize the location.

The core pipe 3 is provided with a first cylinder 32 connected to the inner wall of the air outlet pipe 1 in a sliding manner at one end close to the air outlet pipe 1, and the first cylinder 32 is communicated with the air outlet pipe 1 and the locking pipe 2. The arrangement of the first cylinder 32 improves the smoothness and stability of the core tube 3 sliding on the inner wall of the air outlet tube 1.
