[0024] The following further describes the present utility model with reference to the accompanying drawings in specific embodiments, see Figure 1 — Figure 3 :

[0025] A high-pressure rotary sprinkler head, comprising a water outlet seat 1, an activity sleeve 2 is sleeved on the upper end of the water outlet seat 1. A water passing hole 10 communicating up and down is opened in the water outlet seat 1. A plurality of spray holes 20 with different specifications are circumferentially distributed at the top of the activity sleeve 2. When the activity sleeve 2 rotates circumferentially along the top of the water outlet seat 1, the plurality of spray holes 20 sequentially pass above the water passing hole 10. An installation ring groove 11 is opened on the outer wall of the water outlet seat 1, and a sealing ring abutted against the inner wall of the activity sleeve 2 is arranged in the sealing ring groove 11. A side slot 12 for positioning a "U"-shaped pin is opened on the lower side wall of the water outlet seat 1. A limiting ring platform 13 is opened on the side wall of the water outlet seat 1 above the side slot 12. A protective ring 3 is sleeved on the water outlet seat 1. A plurality of limiting columns 30 are arranged on the inner wall of the protective ring 3. A limiting hook 31 for abutting against the upper end surface of the limiting ring platform 13 is arranged inward at the top of the limiting column 30. The protective ring 3 is located outside the side slot 12.

[0026] During implementation, the bottom of the water passing hole 10 in the water outlet seat 1 is connected to a high-pressure water pipe. A common connection method of the high-pressure water pipe is to be threadedly connected to one end of a connecting pipe, and then the other end of the connecting pipe is fixed to the lower end of the water outlet seat 1 by a "U"-shaped pin. Since the activity sleeve 2 rotates, different positions are rotated to allow the water passing hole 10 to spray out from different spray holes 20 to achieve different water spraying effects.

[0027] In the above structure, since the activity sleeve 2 often rotates, it will cause a certain amount of wear between its barrel wall and the outer wall of the water outlet seat. The provided sealing ring can effectively enhance the sealing performance between the two, so that it is not easy to leak from the cover gap.

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

An abutting ring 14 abutting against the upper end surface of the activity sleeve 2 is arranged on the side wall of the water outlet seat 1.

[0030] In the above structure, the purpose of the transfer ring 4 is to prevent the activity sleeve 2 from falling off from the upper part of the water outlet seat and at the same time ensure the normal rotation of the activity sleeve 2.

[0031] Preferably, an internal thread 100 is opened on the lower hole wall of the water passing hole 10. The internal thread 100 is used for the connecting threaded pipe at the bottom of the water outlet seat 1, so that there are more connection methods between the water outlet seat and the high-pressure water pipe.

[0032] Preferably, an extension pipe 5 is sleeved at the bottom of the water outlet base 1, and a jack 50 for inserting a "U"-shaped pin is formed in the side wall of the extension pipe 5. This is a method for fixing the extension pipe 5 by using a "U"-shaped pin. During installation, after the top of the extension pipe 5 is sleeved on the bottom of the water outlet base 1, the "U"-shaped pin is inserted and locked, and the number of such pins is two.

[0033] In the above structure, a plurality of mounting ring grooves are formed at the bottom of the water outlet base 1 into which the top of the extension pipe 5 is inserted, for installing a sealing ring to enhance the sealing performance between the water outlet base and the extension pipe.

[0034] Preferably, a spray core hole 21 is provided at the bottom of the spray hole 20 on the movable sleeve 2, and a spray core is arranged in the spray core hole 21. The spray core hole is used to accommodate different spray cores, so that the spray core can be disassembled and replaced after being damaged.

[0035] Preferably, a plugging ring 22 is arranged at the bottom of the movable sleeve 2, and a plugging sleeve is arranged at the top of the protective ring 3. When the water outlet base 1 is installed with the protective ring 3, the inner wall of the plugging sleeve abuts against the outer wall of the plugging ring 22.

[0036] After the above structure is installed, the lower end of the movable sleeve can be plugged 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 material, and the bottom threaded connection part is made of stainless steel, which overall improves the strength of the external structure and thus increases the pressure range.

[0038] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
