[0027] Please refer to Figure 1 、 3 , the number of movable hole 8 is several and is annularly distributed with the axis of mounting ring 7 as center, and the bottom end of actuating plate 10 extends to the lower side of mounting ring 7.
[0028] The utility model discloses a kind of natural gas flow nozzle convenient to interface, including nozzle body 1, the lower of nozzle body 1 is provided with connecting pipe 2, the outside of nozzle body 1 and the outside of connecting pipe 2 are respectively fixedly connected with first interface ring 3 and second interface ring 5, first sealing pad 4 and second sealing pad 6 are respectively fixedly connected on first interface ring 3 and second interface ring 5, and first sealing pad 4 and second sealing pad 6 contact, the outside of first interface ring 3 is fixedly connected with mounting ring 7, mounting ring 7 is equipped with movable hole 8, movable hole 8 is fixedly connected with rotating rod 9, movable hole 8 is also provided with actuating plate 10, actuating plate 10 is movably connected in the outside of rotating rod 9, the inside of actuating plate 10 is fixedly connected with catch 11, mounting ring 7 is also provided with clamping assembly 12.
[0029] Please refer to Figure 1 、 3 ,4, clamping assembly 12 includes extruding ring 121, limit groove 122, sliding rod 123 and extruding plate 124, the outside of mounting ring 7 is threadedly connected with extruding ring 121, the inner wall of movable hole 8 is equipped with limit groove 122, and limit groove 122 is located in the outside of actuating plate 10, sliding rod 123 is slidably connected in limit groove 122, extruding plate 124 is also provided in movable hole 8, and the outside of sliding rod 123 is fixedly connected with extruding plate 124.
[0030] In this embodiment, through the above technical solution, the extrusion ring 121 is rotated and moved downward. As the extrusion ring 121 moves, it will drive the extrusion plate 124 to move downward and extrude the actuating plate 10 and the hook 11. On the one hand, it can enhance the limiting effect of the hook 11 and make the nozzle body 1 and the connecting pipe 2 more tightly connected. On the other hand, it can prevent the actuating plate 10 and the hook 11 from falling off.
[0031] Please see Figure 4 The side of the pressing plate 124 closest to the actuating plate 10 is in contact with the actuating plate 10, and the side of the pressing plate 124 furthest from the actuating plate 10 extends to the outside of the mounting ring 7.
[0032] Please see Figure 4 The shape of the slide bar 123 is adapted to the shape of the limiting groove 122, and the width of the mounting ring 7 is greater than the sum of the widths of the first docking ring 3 and the second docking ring 5.
[0033] In this embodiment, through the above technical solution, the slide bar 123 slides in the limiting groove 122, thereby enabling the extrusion plate 124 to move up and down stably for limiting.

At this time, the first sealing gasket 4 on the first docking ring 3 and the second sealing gasket 6 on the second docking ring 5 come into contact, so that the nozzle body 1 and the connecting pipe 2 are initially connected. Then, the actuating plate 10 is rotated to make it fit tightly against the first docking ring 3 and the second docking ring 5. At this time, the hook 11 will hook onto the lower surface of the second docking ring 5, so that the nozzle body 1 and the connecting pipe 2 are connected. The compression ring 121 is rotated and moved downward. As the compression ring 121 moves, it will drive the compression plate 124 to move downward and squeeze the actuating plate 10 and the hook 11, limiting the hook 11 and thus strengthening the sealing between the nozzle body 1 and the connecting pipe 2. This saves a lot of installation and disassembly maintenance work and time, and is suitable for promotion.
