[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model discloses a gas nozzle quick connector, comprising a quick connector assembly 1, wherein the quick connector assembly 1 is arranged at the gas outlet end of an air gun 2.

[0024] The quick connector assembly 1 includes a connecting inner sleeve 11, a locking sleeve 15 and a plurality of nozzle end joints 18, wherein the locking sleeve 15 is movably sleeved on the outside of the connecting inner sleeve 11, a positioning hole 13 is provided on the connecting inner sleeve 11, a circle of limiting rings 16 are provided inside the locking sleeve 15, a positioning notch 17 is provided on the limiting ring 16, and a positioning block 19 is provided on the nozzle end joint 18, wherein one of the nozzle end joints 18 is movably sleeved on the inside of the connecting inner sleeve 11 and the positioning block 19 thereon is sleeved with the positioning hole 13, one end of the limiting ring 16 conflicts with one end of the positioning block 19, see Figure 2 The positioning notch 17 on the limit ring 16 extends all the way to the inner wall of the locking sleeve 15. The width of the limit ring 16 is smaller than the length of the positioning hole 13. The outside of the positioning block 19 is chamfered, and one end of the positioning hole 13 extends all the way to the convex edge 12. When in use, the locking sleeve 15 is rotated, the positioning notch 17 is rotated to be opposite to the positioning hole 13, and the positioning block 19 is inserted after being opposite to the positioning hole 13, so that the nozzle end joint 18 is inserted into the interior of the connecting inner sleeve 11, and the positioning block 19 is inserted into the interior of the positioning hole 13 and staggered with the limit ring 16. At this time, the locking sleeve 15 is rotated so that the positioning notch 17 is staggered with the positioning hole 13, so that one end of the limit ring 16 conflicts with one end of the positioning block 19. When blowing, the nozzle end joint 18 is driven by the air pressure to further conflict with the limiting ring 16, thereby avoiding the loosening of the locking sleeve 15 and further ensuring the connection stability of the nozzle end joint 18.

[0025] Specifically, the number of the positioning holes 13 , the positioning notches 17 and the positioning blocks 19 on the nozzle end joint 18 is no less than two, and the two positioning holes 13 , the positioning notches 17 and the positioning blocks 19 are symmetrically arranged to ensure the connection stability of the nozzle end joint 18 .

[0026] Specifically, one end of the connecting inner sleeve 11 is provided with a threaded head 111 which is threadedly sleeved with the air outlet end of the air gun 2, and the other end is provided with a flange 12 located at one end of the locking sleeve 15. When the connecting inner sleeve 11 is connected to the air gun 2 through the threaded head 111, the flange 12 cooperates with the air outlet end of the air gun 2 to limit the locking sleeve 15, so that the locking sleeve 15 can only rotate but cannot move forward and backward.

[0027] Specifically, the outside of the convex edge 12 is provided with an anti-fool mark 14 opposite to the positioning hole 13, and the outside of the locking sleeve 15 is provided with a locking mark, which is used by the user to identify the locking rotation direction and the unlocking rotation direction of the locking sleeve 15, and the operation is more convenient. The anti-fool mark 14 facilitates the user to observe the position of the positioning hole 13, realizes the blind insertion of the positioning block 19 and the positioning hole 13, and further ensures the assembly efficiency.

[0028] Specifically, it also includes a pressurized flat nozzle 3, which is arranged at one end of one of the nozzle end joints 18, and also includes an integrated nozzle 4, which is arranged at one end of one of the nozzle end joints 18, and also includes a pressurized nozzle 5, which is arranged at one end of one of the nozzle end joints 18, and also includes a flat-mouth nozzle 6, which is arranged at one end of one of the nozzle end joints 18, and also includes an tracheal nozzle 7, which is arranged at one end of one of the nozzle end joints 18, and also includes a rubber nozzle 8, which is arranged at one end of one of the nozzle end joints 18. The types of nozzles are not limited to the above-mentioned ones. By setting a number of nozzle end joints 18, nozzles for different purposes can be designed for replacement and use to meet the user's usage needs under different working conditions and different scenarios, and the nozzle end joint 18 has the characteristics of quick disassembly and assembly, simple operation method, and high practicality.

[0029] To sum up, the air nozzle quick connector, through the cooperation of the positioning hole 13, the limiting ring 16, the positioning notch 17 and the positioning block 19, can lock and unlock the mouthpiece end connector 18 by rotating the locking sleeve 15. The operation is simple and quick, and the mouthpiece end connector 18 can be quickly disassembled and assembled. By setting up a plurality of mouthpiece end connectors 18, mouthpieces for different purposes can be designed for replacement and use, thereby meeting the user's needs under different working conditions and scenarios. The mouthpiece end connector 18 has the characteristics of quick disassembly and assembly, simple operation and high practicality.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
