Description

Technical Field

[0001] The utility model relates to the field of cavitation water jet equipment, and more specifically, to a segmented assembled cavitation water jet nozzle. Background Art

[0002] Water jet technology uses high pressure and a constant flow rate to impart tremendous energy to water, ejecting it from a tiny nozzle at high speed, creating a highly concentrated stream of water for cleaning. Cavitation water jetting is a key technology within this technology. By creating cavitation within the jet, it achieves the same cleaning effect while significantly reducing system operating pressure, thereby effectively lowering costs and facilitating manual operation.

[0003] To facilitate portability, existing cavitation water jet nozzles often separate the nozzle head and straight tube into two sections, with threads inserted at the connection. During installation, the two sections are connected by rotating one section. However, in actual use, because nozzles are often used to clean narrow spaces such as pipes, the impact of the water jet from the nozzle and the inner wall of the pipe can easily cause the nozzle to vibrate. Over extended cleaning processes, the nozzle head and straight tube can easily loosen at the threaded portion, potentially causing the nozzle to fall off.

[0004] Therefore, in order to solve the above problems, a segmented assembled cavitation water jet nozzle is proposed. Utility Model Content

[0007] 2. Technical solution

[0009] A segmented assembled cavitation water jet nozzle comprises a nozzle section and a straight pipe section, the nozzle section being threadedly connected to the straight pipe section, the outside of the nozzle section being rotatably connected to a rotating frame, the outside of the nozzle section being fixedly connected to a connecting frame, the outside of the straight pipe section being fixedly connected to a fixed frame, the connecting frame being rotatably connected to the rotating frame, the inner annular surface of the rotating frame being a toothed surface, four evenly arranged bolts being threadedly connected through one side of the connecting frame, the four bolts being fixedly connected to gears at one end close to the rotating frame, the four gears being meshed with the inner annular surface of the rotating frame, four evenly distributed threaded holes being opened on one side of the fixed frame, the four bolts being threadedly connected to the four threaded holes respectively.

[0010] Furthermore, the outside of the connection frame is fixedly connected with four evenly distributed mounting plates, and the four mounting plates and the four bolts are staggered on the connection frame.

[0029] Example:

[0030] See also Figure 1 - Figure 4A segmented assembled cavitation water jet nozzle includes a nozzle section 1 and a straight pipe section 2. The nozzle section 1 is threadedly connected to the straight pipe section 2. The outside of the nozzle section 1 is rotatably connected to a rotating frame 3, the outside of the nozzle section 1 is fixedly connected to a connecting frame 4, and the outside of the straight pipe section 2 is fixedly connected to a fixed frame 5. The connecting frame 4 is rotatably connected to the rotating frame 3, and the inner ring surface of the rotating frame 3 is a tooth surface. Four evenly arranged bolts 7 are threadedly connected to one side of the connecting frame 4. The four bolts 7 are fixedly connected to one end of the rotating frame 3, and the four gears 6 are meshed with the inner ring surface of the rotating frame 3. Four evenly distributed threaded holes 8 are opened on one side of the fixed frame 5, and the four bolts 7 are threadedly connected to the four threaded holes 8 respectively.

[0031] In this solution, the nozzle section 1 and the straight pipe section 2 are provided with threads that can be connected to each other, and after the two are fully threaded and tightened, the positions of the four bolts 7 and the four threaded holes 8 correspond. During installation, the staff first thread the nozzle section 1 and the straight pipe section 2 together, and then manually twist the rotating frame 3. Through the tooth surface of the inner ring of the rotating frame 3, the four gears 6 drive the bolts 7 to rotate, so that the bolts 7 enter the threaded holes 8, thereby achieving reinforcement and fixation of the nozzle section 1 and the straight pipe section 2. At the same time, the meshing self-locking effect between the tooth surface of the inner ring of the rotating frame 3 and the gear 6 can make the connection between the nozzle section 1 and the straight pipe section 2 tighter when the nozzle is working, thereby effectively avoiding the phenomenon of loosening of the nozzle connection due to water flow impact and obstacle collision.

[0032] See also Figure 1 - Figure 5 The outside of the connecting frame 4 is fixedly connected with four evenly distributed mounting plates 9 , and the four mounting plates 9 and four bolts 7 are staggered on the connecting frame 4 .

[0033] Specifically, one side of each of the four mounting plates 9 is provided with a positioning hole 10 , and the outer ring surface of the fixing frame 5 is provided with four evenly distributed positioning grooves 11 . The positions of the four positioning holes 10 correspond to the positions of the four positioning grooves 11 .

[0034] Specifically, four evenly distributed slots 12 are formed on one side of the fixing frame 5 , and the four slots 12 are respectively connected to the four positioning slots 11 .

[0035] Specifically, the interiors of the four positioning holes 10 are all slidably connected with positioning posts 13 , and the four positioning posts 13 are slidably connected to the four positioning grooves 11 , respectively.

[0036] Specifically, elastic inserts 15 are slidably connected to the interior of the four slots 12 , and a clamping slot 14 is provided on the exterior of the positioning post 13 . The four positioning posts 13 are respectively clamped with the four elastic inserts 15 through the clamping slots 14 provided thereon.

[0037] In this solution, after the nozzle section 1 and the straight pipe section 2 are fastened by their own threaded connection, the four positioning holes 10 and the four positioning grooves 11 correspond one to one. After the bolts 7 and the threaded holes 8 are connected, the staff inserts the four positioning columns 13 into the four positioning grooves 11 through the four positioning holes 10 respectively, and then inserts the four elastic inserts 15 from the four card slots 14. The opening of the elastic insert 15 has a certain elasticity and can produce a certain degree of deformation. The opening of the elastic insert 15 is engaged with the card slot 14, so that the positioning column 13 cannot be detached from the positioning groove 11 and the positioning hole 10. At the same time, the positioning column 13 also plays a limiting role on the elastic insert 15. The elastic insert 15 can only be removed from the card slot 14 by the staff by hand or with tools, thereby further improving the fixing effect of the nozzle section 1 and the straight pipe section 2.

[0038] Working principle: During installation, the staff first threadedly connects the nozzle section 1 and the straight pipe section 2 together, and then manually twists the rotating frame 3. Through the tooth surface of the inner ring of the rotating frame 3, the four gears 6 drive the bolts 7 to rotate, so that the bolts 7 enter the threaded holes 8, thereby achieving the reinforcement and fixation of the nozzle section 1 and the straight pipe section 2. Then the staff inserts the four positioning columns 13 into the four positioning grooves 11 through the four positioning holes 10 respectively, and then inserts the four elastic inserts 15 from the four card slots 14. The opening of the elastic insert 15 is engaged with the card slot 14, so that the positioning column 13 cannot be detached from the positioning groove 11 and the positioning hole 10. At the same time, the positioning column 13 also plays a limiting role on the elastic insert 15, which further improves the fixing effect of the nozzle section 1 and the straight pipe section 2.

[0039] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
