Description

Technical Field

[0001] This utility model relates to the field of high-pressure nozzle technology, specifically a high-pressure cleaning nozzle with adjustable pressure. Background Technology

[0002] A high-pressure cleaning nozzle is a specialized cleaning device. It works by pressurizing water or gas to a certain level using a high-pressure pump and then spraying it out at high speed through a nozzle. It is usually used in conjunction with a high-pressure cleaner to generate high-pressure water or gas streams for flushing and removing dirt from various surfaces and inside pipes.

[0003] Currently, patent CN204448343U discloses an ultra-high pressure rotary nozzle, including a nozzle housing, a rotating blade inside the nozzle housing, a nozzle core sleeve at the end of the rotating blade, the nozzle core sleeve making point contact with the rotating blade, and the nozzle core positioned on top of the nozzle core sleeve. Water flow through the rotating blade generates centrifugal force, driving the nozzle core sleeve and thus rotating the nozzle core. A nozzle is located at the water outlet end of the nozzle housing, and the nozzle core extends into the nozzle. The buffer mechanism includes a buffer plate, a buffer spring, a connecting nut, and a rotating blade shaft. The connecting nut is fixed to the water inlet end of the nozzle housing. The rotating blade shaft is threadedly connected to the center of the connecting nut. A rotating blade seat is mounted on the rotating blade shaft and can rotate around it, while also being able to move axially within a small range. A buffer spring is located inside the connecting nut, and a buffer plate is positioned between the buffer spring and the rotating blade seat. This ultra-high pressure rotary nozzle uses the centrifugal force of water flow through the rotating blade to drive the nozzle core to rotate, and a buffer mechanism behind the rotating blade eliminates the impact force at the moment of firing. This rotary nozzle has excellent wear resistance and impact resistance, is not easily damaged, and has a long service life.

[0004] However, the above-mentioned high-pressure rotary nozzle still has the following problems during use: the water pressure can only be changed by the high-pressure pump, but in actual use, because there is a certain distance between the high-pressure pump and the nozzle, it is necessary to go to the location of the high-pressure pump to adjust the water pressure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-pressure cleaning nozzle with adjustable pressure. The water outlet hole is adjusted by rotation, thereby regulating the water pressure. The adjusted sleeve is fixed by a locking mechanism.

[0006] This utility model provides the following technical solution: a high-pressure cleaning nozzle with adjustable pressure, comprising a cleaning nozzle housing, an inlet pipe fixedly installed through its upper end, a water control plate fixedly installed on the inner surface of the cleaning nozzle housing, a connecting shaft rotatably installed at the lower end of the water control plate, a water outlet plate fixedly installed at the lower end of the connecting shaft, a nozzle tube penetrating through the lower end of the water outlet plate, an adjusting sleeve fixedly installed outside the water outlet plate, the adjusting sleeve being located outside the cleaning nozzle housing, a locking plate installed on the outer surface of the cleaning nozzle housing, a fixing plate installed outside the adjusting sleeve, a positioning rod penetrating through the fixing plate, and the positioning rod fitting against the locking plate.

[0007] Furthermore, a protective sleeve is fixedly installed on the upper end of the outer surface of the cleaning nozzle housing, and the protective sleeve is configured as a spiral structure. The protective sleeve is located outside the water inlet pipe. Through the above structure, the water inlet pipe can be protected under the action of the protective sleeve.

[0008] Furthermore, the water outlet plate has six through holes at equal angles, and an arc-shaped groove is provided at the upper end of the water outlet plate. Through the above structure, the water flow speed can be controlled through the water outlet plate.

[0009] Furthermore, a sealing ring is fixedly installed on the upper end of the water control plate, and the sealing ring is made of annular rubber material. The sealing ring and the arc-shaped groove opened on the upper end of the water outlet plate fit together with each other. Through the above structure, the sealing performance between the water outlet plate and the water control plate can be improved under the action of the sealing ring, so as to prevent water from overflowing.

[0010] Furthermore, the outer surface of the adjusting sleeve is fixedly equipped with anti-slip protrusions, and a semi-circular groove is provided on the adjusting sleeve. A limiting ball is slidably arranged in the semi-circular groove on the adjusting sleeve. The limiting ball is rolled on the outer surface of the cleaning nozzle housing. Through the above structure, the adjusting sleeve can be supported and limited under the action of the limiting ball, so that the rotation of the adjusting sleeve is not affected while supporting the adjusting sleeve.

[0011] Furthermore, a positioning spring is fixedly installed on the positioning rod, and the positioning spring is fixedly installed at the lower end of the fixing plate. There are a total of six locking plates. Through the above structure, the locking plates and the fixing plate can be locked and limited under the action of the positioning rod, so as to lock and fix the adjusting sleeve and prevent the adjusting sleeve from rotating during use.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This pressure-adjustable high-pressure cleaning nozzle allows for rotation of the nozzle tube by rotating the adjusting sleeve. This changes the contact position between the upper end of the nozzle tube and the water outlet plate, enabling adjustment of the water pressure through orifices of different diameters. After adjustment, the positioning rod engages and secures the locking plate and the fixing plate, thus locking and securing the adjusting sleeve to prevent rotation during subsequent use and ensuring its stability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-6This utility model provides a technical solution: a high-pressure cleaning nozzle with adjustable pressure, including a cleaning nozzle housing 1, with a water inlet pipe 2 fixedly installed through its upper end; a water control plate 6 fixedly installed on the inner surface of the cleaning nozzle housing 1, and a connecting shaft 5 rotatably installed at the lower end of the water control plate 6; a water outlet plate 4 fixedly installed at the lower end of the connecting shaft 5, with a nozzle pipe 8 penetrating through the lower end of the water outlet plate 4; an adjusting sleeve 9 fixedly installed outside the water outlet plate 4, and the adjusting sleeve 9 is located outside the cleaning nozzle housing 1; a locking plate 12 is installed on the outer surface of the cleaning nozzle housing 1, and the adjusting sleeve... A fixing plate 13 is installed on the outside of the 9th part. A positioning rod 14 is installed through the fixing plate 13 and fits with the locking plate 12. A protective sleeve 3 is fixedly installed on the upper surface of the outer surface of the cleaning nozzle housing 1. The protective sleeve 3 is set with a spiral structure and is set outside the water inlet pipe 2. Six through holes are opened at equal angles on the water outlet plate 4 and an arc-shaped groove is opened at the upper end of the water outlet plate 4. A sealing ring 7 is fixedly installed on the upper end of the water control plate 6. The sealing ring 7 is made of annular rubber material and fits with the arc-shaped groove opened at the upper end of the water outlet plate 4.

[0023] When the spray pressure of the nozzle needs to be adjusted, rotate the adjusting sleeve 9. Because the adjusting sleeve 9 has anti-slip protrusions 10 on its exterior, it allows for quick and easy rotation without slipping. Since the lower end of the adjusting sleeve 9 is fitted with a water outlet plate 4, and the lower end of the water outlet plate 4 is fixedly fitted with a nozzle tube 8, the nozzle tube 8 begins to rotate. Simultaneously, the water outlet plate 4 begins to rotate under the action of the connecting shaft 5. Because the water control plate 6 has eccentrically opened holes, nozzle tubes 8 of different diameters rotate to the position of the eccentrically opened holes on the water control plate 6, allowing for the replacement of the nozzle tube 8. Since the diameter of the nozzle tube 8 varies at different positions, the water flow from the nozzle tube 8 varies accordingly. The flow rate and pressure change because the water control plate 6 is equipped with a sealing ring 7, and the sealing ring 7 fits tightly with the water outlet plate 4. Under the action of the sealing ring 7, the sealing effect between the water outlet plate 4 and the water control plate 6 can be guaranteed, preventing water from overflowing. At this time, the high-pressure pump starts to work. Because the high-pressure pump is connected to the water inlet pipe 2, the high-pressure water in the water inlet pipe 2 enters the cleaning nozzle housing 1. Under the action of the protective sleeve 3, the water inlet pipe 2 can be protected, preventing bending and breakage at the connection of the water inlet pipe 2. During the rotation of the adjusting sleeve 9, the limiting ball 11 can support and limit the adjusting sleeve 9, preventing the adjusting sleeve 9 from shaking during the rotation.

[0024] A locking plate 12 is installed on the outer surface of the cleaning nozzle housing 1, and a fixing plate 13 is installed on the outside of the adjusting sleeve 9. A positioning rod 14 is provided through the fixing plate 13, and the positioning rod 14 is in contact with the locking plate 12. A positioning spring 15 is fixedly installed on the positioning rod 14, and the positioning spring 15 is fixedly installed at the lower end of the fixing plate 13. There are a total of six locking plates 12.

[0025] Before rotating the adjusting sleeve 9, pull down the positioning rod 14. The positioning rod 14 will then move away from the fixed plate 13. Because a positioning spring 15 is fixedly installed on the positioning rod 14, and the fixed plate 13 is fixedly installed on the upper end of the positioning spring 15, the positioning spring 15 will be stretched and deformed until the positioning rod 14 is no longer in contact with the locking plate 12. Then the adjusting sleeve 9 can be rotated. Because six locking plates 12 are set at equal angles on the outside of the cleaning nozzle housing 1, and the six locking plates 12 correspond to six nozzle tubes 8 with different diameters, the positioning rod 14 can be released after rotating to the appropriate position. Under the action of the positioning spring 15 restoring its deformation, the positioning spring 15 will start to pull the positioning rod 14, and the positioning rod 14 will start to be in contact with and fixed to the locking plate 12. This will lock and fix the adjusting sleeve 9, preventing the adjusting sleeve 9 from rotating during subsequent use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
