[0038] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] like Figure 1-13 As shown, a high-pressure water gun nozzle mechanism includes a gun body 100, a handle 200, an inlet pipe 300, and an outlet pipe 400. The handle 200 is connected to one end of the gun body 100, and the outlet pipe 400 is connected to the other end of the gun body. The inlet pipe 300 is located at the bottom of the gun body 100. The high-pressure water gun nozzle 500 mechanism also includes a nozzle 500 and a connector 600. One end of the connector 600 is detachably connected to the outlet pipe 400, and the other end is detachably connected to the nozzle 500. The connector 600 has a passage cavity for water flow.

[0040] Specifically, one end of the connector 600 is provided with a connecting plate 602, and the connecting plate 602 is provided with a first protrusion 603. The connecting plate 602 is made of an elastic material, preferably plastic. The inner wall of the nozzle 500 is provided with a protruding ring 505, and the bottom is provided with a second protrusion 506. The second protrusion 506 is provided with a guide groove 507, and the guide groove 507 is inclined so that the second protrusion 506 has a spiral structure along the bottom surface of the protruding ring 505. When the nozzle 500 is fitted onto the connector 600, the bottom end of the guide groove 507 on the second protrusion 506 is aligned with the first protrusion 603 to prevent the nozzle 500 from being fitted onto the connector 600. When the nozzle 500 is mounted on the connector 600, it is obstructed by the first protrusion 603. After the nozzle 500 is mounted on the connector 600, the nozzle 500 rotates relative to the connector 600. The first protrusion 603 moves along the side wall of the guide groove 507, so that the first protrusion 603 moves to the top position of the inclined surface of the guide groove 507. The second protrusion 506 presses the first protrusion 603, causing the connecting plate 602 to bend. The reaction force of the connecting plate 602 on the first protrusion 603 causes the first protrusion 603 to abut against the second protrusion 506. The nozzle 500 is fixed on the connector 600 by the cooperation of the first protrusion 603 and the second protrusion 506.

[0041] Furthermore, the connector 600 is provided with a connecting plate 604, and the nozzle 500 has a conical structure with a boss on the nozzle 500 corresponding to the connecting plate 604.

[0042] The nozzle 500 has a groove 501 on its side wall, a through groove on its side wall, a fixing plate 502 on the inner wall of the through groove, and a gap between the fixing plate 502 and the inner wall of the other side of the through groove. The width of the gap corresponds to the thickness of the connecting plate 604. The fixing plate 502 is made of elastic material, and a guide surface is provided on the side wall of the fixing plate 502. The guide surface is inclined.

[0043] When the nozzle 500 is fitted onto the connector 600, the connecting plate 604 enters the nozzle 500. Due to the setting of the fixing plate 502, the inner diameter of the large-diameter end of the nozzle 500 is smaller than the diameter of the connecting plate 604. The connecting plate 604 abuts against the guide surface of the fixing plate 502, pushing the fixing plate 502 outwards into the through groove until the connecting plate 604 moves to the gap between the fixing plate 502 and the through groove. The connecting plate 604 then extends out from the gap and is clamped between the fixing plate 502 and the inner wall of the through groove. The nozzle 500 is fixed onto the connector 600 by using the connecting plate 604. The initial fixation of the nozzle 500 can be achieved simply by fitting the nozzle 500 onto the connector 600. The operation is simple and convenient.

[0044] Furthermore, the connector 600 is provided with a support plate 605, which positions the nozzle 500 to be fitted into. The support plate 605 is provided with a movable ring, and the inner wall of the movable ring is provided with a plurality of first ribs. The side wall of the nozzle is provided with a connecting ring 503, and the connecting ring 503 is provided with a plurality of second ribs 504.

[0045] The support plate 605 is provided with a first slider 617, and the inner wall of the movable ring is provided with a first groove 616 for the first slider 617 to move; the inner wall of the movable ring is provided with a plurality of first movable grooves 609, and a rotating wheel 610 is provided in the first movable groove 609, and a fixing block 611 is provided on the rotating wheel 610; the movable ring is provided with an annular groove, which communicates with the first movable groove 609, and a rotating ring 606 is provided in the annular groove, and the rotating ring 606 is in a transmission cooperation with the rotating wheel 610.

[0046] The inner wall of the annular groove is provided with a second sliding groove 612, and the two ends of the second sliding groove 612 are respectively provided with a first limiting groove 6121 and a second limiting groove 6122; the rotating ring 606 is provided with a third protrusion 607, the third protrusion 607 is provided with a second movable groove, the second movable groove is provided with a movable plate 614, the movable plate 614 is provided with a second slider 613, and the second slider 613 is inserted into the second sliding groove 612; the bottom of the second movable groove is provided with an elastic support plate 615, which is an arc-shaped metal sheet, and the top of the movable plate 614 is provided with a push block 608.

[0047] After the nozzle 500 is fitted onto the connector 600, the movable ring is pushed towards the nozzle 500. The movement of the movable ring causes the first rib to insert into the gap of the adjacent second rib 504. The cooperation of the first and second ribs 504 forms a connection between the nozzle 500 and the movable ring, thereby achieving a non-rotational fit between the nozzle 500 and the connector 600, preventing the nozzle 500 from rotating and affecting the connection effect. After the movable ring moves, it pushes the push block 608 to move, which moves towards the third protrusion 607 and drives the second slider 613 to move. The second slider 613 moves out of the first limiting groove 6121 and into the second sliding groove 612, pushing the third protrusion 607 to move and causing the rotating ring 606 to rotate. The rotating ring 606 drives the rotating wheel 610 to rotate, causing the fixing block 611 to rotate out of the first movable groove 609. The fixing block 611 abuts against the support plate 605 and cooperates with the sliding groove to fix the movable ring, ensuring the connection effect of the nozzle 500.

[0048] There are two third protrusions 607. The push block 608, the limiting groove and the two third protrusions 607 are used to prevent the nozzle 500 from falling off the connector 600 after accidental contact.

[0049] One end of the water outlet pipe 400 is provided with a connecting frame, and the other end of the connector 600 is provided with a fourth protrusion 601. The connecting frame is provided with a fixing groove corresponding to the fourth protrusion 601. A connecting sleeve 700 is also provided on the water outlet pipe 400 to fix the connector 600 on the water outlet pipe 400.
