[0025] A flange 4 is fixedly connected to one end of the butt-joint pipe 2 away from the conical pipe 3 , and a plurality of mounting holes 5 are formed on the side of the flange 4 .

[0026] The butt-joint pipe 2 can be fixedly connected to the pipeline of the aeration device through the flange 4 and the mounting hole 5 on the flange 4 .

[0027] An annular ridge 62 is provided on the inner wall of the tapered opening 61 , and the annular ridge 62 is in contact with the outer wall of the hose 1 .

[0028] When the tapered opening 61 is pressed against the surface of the hose 1 , the annular ridge 62 will be further clamped and pressed against the surface of the hose 1 , thereby fixing the hose 1 on the surface of the tapered tube 3 .

[0029] A thread groove 63 is formed on the internal threaded tube 6 near the tapered opening 61 , and an extrusion screw 7 is rotatably connected inside the thread groove 63 .

[0030] By rotating the extrusion screw 7 so that the extrusion screw 7 is pressed against the surface of the hose 1 , the hose 1 and the tapered tube 3 can be further fixed.

[0031] The clamping assembly 8 includes a groove 81 opened on the outer wall of the butt tube 2, a spring 82 is fixedly connected to the inner wall of the groove 81, and a clamping rod 83 is fixedly connected to the other end of the spring 82. The clamping rod 83 is clamped into the clamping hole 66 at one end away from the spring 82.

[0032] When the internal threaded tube 6 is screwed onto the surface of the butt joint tube 2 and the clamping hole 66 is aligned with the clamping rod 83, the spring 82 will push the clamping rod 83 out of the groove 81 so that the clamping rod 83 is clamped into the clamping hole 66, thereby increasing the firmness of the connection between the internal threaded tube 6 and the butt joint tube 2.

When the bevel groove 65 of the internal threaded pipe 6 fits the clamping rod 83, the bevel groove 65 squeezes the clamping rod 83 back into the groove 81. When the clamping hole 66 is aligned with the clamping rod 83, the spring 82 will push the clamping rod 83 out of the groove 81, so that the clamping rod 83 is clamped into the clamping hole 66. During this process, the tapered mouth 61 and the annular ridge 62 will continuously squeeze the hose 1, so that the hose 1 is fixed on the surface of the tapered pipe 3, and finally tighten the extrusion screw 7. When disassembling the hose 1 later, you only need to loosen the extrusion screw 7, then press the clamping rod 83 to disengage from the clamping hole 66, and then unscrew the internal threaded pipe 6 from the surface of the butt joint 2. After the hose 1 loses the extrusion force, it can be disassembled from the surface of the tapered pipe 3. Moreover, this connection method is not only convenient for disassembly and assembly, but also can be used to install hoses 1 of different diameters.
