Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of live cleaning guns, in particular to a rotary nozzle of a live cleaning gun. Background Art
[0002] The rotating nozzle of the live cleaning gun is a structure installed at the top of the live cleaning gun for spraying internal fluid. Its main connection method is to use a threaded connection to connect to the top of the live cleaning gun. This connection method will also generate a certain impact pressure at the connection when the internal fluid is sprayed, which can easily cause the nozzle to separate from the gun body. In addition, the sealing is poor after long-term use, which can easily cause the fluid to overflow from the connection. Therefore, the existing device needs to be improved to meet actual needs.

[0025] Specifically, a group of thread grooves 2 are provided on the inner wall of the connecting pipe 1. The advantage is that the thread grooves 2 facilitate the connection between the connecting pipe 1 and the cleaning gun, thereby making a preliminary connection to the device, which is convenient for installation.
[0026] Specifically, a group of trumpet-shaped nozzles 31 are fixedly mounted on the top of the nozzle body 3. The advantage is that after the connecting pipe 1 is connected to the cleaning gun, a main rotating nozzle device is formed through the connecting pipe 1, the nozzle body 3 and the trumpet-shaped nozzle 31. After the internal fluid is ejected, the ejected fluid is diffused through the trumpet-shaped nozzle 31, making the ejection surface more comprehensive and extensive.
[0027] Specifically, two groups of first threaded rods 5 are installed through the threads at both ends of the outer side of the protective plate 4, and a group of arc plates 7 are installed at the bottom of each group of first threaded rods 5 through bearings, and two groups of ear blocks 9 are relatively fixedly installed on the sides of each group of arc plates 7. The advantage is that after the connecting pipe 1 is threadedly connected to the cleaning gun, the two groups of first threaded rods 5 are rotated respectively, so that the first threaded rods 5 drive the corresponding arc plates 7 to make linear motion toward the connecting port through the bearings, until the two groups of arc plates 7 overlap each other, the connecting port is fixed and closed, and then the second threaded rods 10 are threadedly connected to the corresponding ear blocks 9, and the two ends of the second threaded rods 10 are fixed by nuts 11, which increases the stability of the connecting pipe 1 after being connected to the cleaning gun and avoids the problem of falling off.
[0028] Specifically, a group of rubber sealing layers 8 are fixedly disposed on the inner wall of each group of arc plates 7. The advantage is that when the two groups of first threaded rods 5 drive the two groups of arc plates 7 to fix the interface between the connecting pipe 1 and the cleaning gun, the two groups of arc plates 7 drive the corresponding rubber sealing layers 8 to be relatively close, thereby increasing the sealing performance at the interface between the connecting pipe 1 and the cleaning gun and reducing the problem of internal fluid leakage.
[0029] When in use, firstly, the threaded groove 2 is used to facilitate the connection between the connecting pipe 1 and the cleaning gun, so as to make a preliminary connection to the device for easy installation. After the connecting pipe 1 is connected to the cleaning gun, a main rotating nozzle device is formed by the connecting pipe 1, the nozzle body 3 and the trumpet-shaped nozzle 31. After the internal fluid is sprayed out, the sprayed fluid is diffused through the trumpet-shaped nozzle 31, so that the spraying surface is more comprehensive and extensive. After the connecting pipe 1 is threadedly connected to the cleaning gun, the two groups of first threaded rods 5 are rotated respectively, so that the first threaded rods 5 drive the corresponding arc plates 7 to connect to each other through the bearings. The two groups of arc plates 7 are linearly moved until the two groups of arc plates 7 overlap each other, and the connection port is fixed and closed, and then the second threaded rod 10 is threadedly connected to the corresponding ear block 9.
