[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, see Figures 1-3:

[0025] A high-pressure rotary nozzle includes a water outlet base 1, with a movable sleeve 2 fitted onto the upper end of the water outlet base 1. The water outlet base 1 has a water passage hole 10 communicating vertically. The top of the movable sleeve 2 has several nozzles 20 of different sizes distributed circumferentially. When the movable sleeve 2 rotates circumferentially along the top of the water outlet base 1, the nozzles 20 sequentially pass above the water passage hole 10. An installation annular groove 11 is provided on the outer wall of the water outlet base 1, and a sealing annular groove 11 is provided with a fitting that corresponds to the movable sleeve 20. The inner wall of the sleeve 2 is abutted by a sealing ring. The lower side wall of the water outlet seat 1 is provided with a side slot 12 for positioning with a "U" shaped pin. The side wall of the water outlet seat 1 is provided with a limiting ring platform 13 located above the side slot 12. The water outlet seat 1 is fitted with a protective ring 3. The inner wall of the protective ring 3 is provided with a plurality of limiting posts 30. The top of the limiting post 30 is provided with a limiting hook 31 for abutting against the upper end face of the limiting ring platform 13. The protective ring 3 is located outside the side slot 12.

[0026] During implementation, the bottom of the water outlet 10 inside the water outlet base 1 is connected to a high-pressure water pipe. The common connection method for the high-pressure water pipe is to use a threaded connection to one end of the connecting pipe, and then fix the other end of the connecting pipe to the lower end of the water outlet base 1 with a "U" pin. Since the movable sleeve 2 rotates in different positions, the water outlet 10 sprays water from different nozzles 20, achieving different water spraying effects.

[0027] In the above structure, since the movable sleeve 2 will rotate frequently, its cylinder wall will wear against the outer wall of the water outlet seat. The sealing ring can effectively enhance the sealing performance between the two, thus making it less likely for leakage to occur from the cover gap.

[0028] In addition, the protective ring is connected to the water outlet seat 1 by a plug-in connection to provide waterproof protection for the "U" pin and ensure the long-term use of the connection.

[0029] Preferably, a transition ring 4 is sleeved on the side wall of the water outlet seat 1, the inner wall of the movable sleeve 2 is threadedly connected to the outer wall of the transition ring 4, and an abutment ring 14 is provided on the side wall of the water outlet seat 1 to abut against the upper end face of the movable sleeve 2.

[0030] In the above structure, the purpose of the adapter ring 4 is to prevent the movable sleeve 2 from falling off the top of the water outlet seat, while ensuring the normal rotation of the movable sleeve 2.

[0031] Preferably, the lower wall of the water passage 10 is provided with an internal thread 100. The internal thread 100 is used to connect the threaded pipe at the bottom of the water outlet 1, allowing for more connection methods between the water outlet and the high-pressure water pipe.

[0032] Preferably, the bottom of the water outlet base 1 is fitted with an extension tube 5, and the side wall of the extension tube 5 has a socket 50 for inserting a "U"-shaped pin. This is a method of fixing the extension tube 5 using a "U"-shaped pin. During installation, after the top of the extension tube 5 is fitted onto the bottom of the water outlet base 1, two "U"-shaped pins are inserted to lock it in place.

[0033] In the above structure, the bottom of the water outlet seat 1 at the top of the extension tube 5 is provided with several mounting ring grooves for installing sealing rings to enhance the sealing between the water outlet seat and the extension tube.

[0034] Preferably, the movable sleeve 2 is provided with a nozzle core hole 21 located at the bottom of the nozzle 20, and a nozzle core is disposed in the nozzle core hole 21. The nozzle core hole is used to prevent different nozzle cores from being replaced, so that the nozzle core can be disassembled and replaced after damage.

[0035] Preferably, the bottom of the movable sleeve 2 is provided with a plug-in ring 22, and the top of the protective ring 3 is provided with a plug-in sleeve 30. When the water outlet seat 1 is installed with the protective ring 3, the inner wall of the plug-in sleeve 30 abuts against the outer wall of the plug-in ring 22.

[0036] After installation, the above structure allows the lower end of the movable sleeve to be inserted and sealed with the upper end of the protective ring 3, thereby further enhancing the waterproof and protective effects.

[0037] In the above structure, the movable sleeve 2 is made of aluminum, the protective ring is made of nylon, and the bottom threaded connection is made of stainless steel, which improves the overall strength of the external structure and thus increases the pressure range.

[0038] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
