The rubber-plastic pipe has a low thermal conductivity and a completely closed-cell structure, and has a long-lasting and good insulation effect. The material is completely isolated from water vapor, does not absorb water, is not easy to burn, does not condense, and has a long service life. After SGS testing, the actual measured value is far lower than the EU standard value for non-toxic substances, and it is healthy and safe to use. The automotive industry is the most widely used industry. The air conditioning exhaust system of the car and the drainage system of the sunroof are inseparable from rubber-plastic pipes.

Through the arrangement of the positioning component 9, the metal mesh rubber and plastic tube body 1 and the butt-joint tube 2 can be quickly installed and disassembled, thereby improving the disassembly efficiency of the metal mesh rubber and plastic tube.

[0020] See also Figure 1-2 In the embodiment of the utility model: the inner walls of both ends of the metal mesh rubber-plastic tube body 1 are fixedly mounted with positioning rings 5, and the interior of the positioning rings 5 ​​is provided with sealing rings 6, and the end of one end of the butt joint tube 2 is placed inside the positioning rings 5, and the two sides of the sealing rings 6 are respectively fitted with the side walls of the butt joint tube 2 and the interior of the metal mesh rubber-plastic tube body 1. After the metal mesh rubber-plastic tube body 1 is installed at the position of one end of the butt joint tube 2, the positioning ring 5 cooperates with the sealing ring 6, so that the sealing ring 6 plays a sealing role on the connection between the butt joint tube 2 and the metal mesh rubber-plastic tube body 1, thereby improving the sealing performance of the butt joint of the metal mesh rubber-plastic tube.

[0021] See also Figure 1-2 In the embodiment of the utility model, the diameter of the push ring 7 is larger than the diameter of the sleeve 4. When the metal mesh rubber-plastic tube body 1 and the butt joint tube 2 are butted together, since the diameter of the push ring 7 is larger than the diameter of the sleeve 4, it is convenient to push the push ring 7 to move the sleeve 4 toward the butt joint tube 2, thereby butt jointing the metal mesh rubber-plastic tube body 1 and the butt joint tube 2.

[0022] See also Figure 1-2 In the embodiment of the utility model: the positioning component 9 includes: a positioning groove 901 and a movable groove 902, the positioning groove 901 is arranged on the surface of the outer ring of the fixed ring 3, the movable groove 902 is arranged through the inside of the sleeve ring 4, the movable groove 902 corresponds to the adjacent positioning groove 901, and a movable pin 903 is arranged through the inside of the movable groove 902 in the vertical direction, and one end of the movable pin 903 extends to the inside of the positioning groove 901, and the other end of the movable pin 903 is mounted on the inner wall of the push ring 7, and the surface of the other end of the movable pin 903 is fixedly connected to the limiting ring 904, and the middle part of the movable pin 903 is sleeved with a second return spring 905, and one end of the second return spring 905 is fixedly connected to the surface of one side of the limiting ring 904, and the other end of the second return spring 905 is fixedly connected to the inner wall of the movable groove 902. When the metal mesh rubber and plastic tube body 1 is docked with the docking tube 2, the push ring 7 mounted on the surface of the ring 4 is pushed, so that the ring 4 drives one end of the metal mesh rubber and plastic tube body 1 to move toward the corresponding docking tube 2. After the end of one end of the docking tube 2 is pressed against the inner wall of the positioning ring 5 on the inner wall of the metal mesh rubber and plastic tube body 1, the push ring 7 is moved toward the docking tube 2 by continuing to push the push ring 7. At this time, the inner wall of the push ring 7 simultaneously squeezes the inclined surface of the other end of the four movable pins 903, so that the movable pins 903 move toward the corresponding positioning grooves 901, completing the rapid docking of the metal mesh rubber and plastic tube body 1 and the docking tube 2. At the same time, the first return spring 8 elastically resets the side of the push ring 7 that is always pushed, limits the movement of the push ring 7, and improves the stability of the inner wall of the push ring 7 squeezing the other end of the movable pin 903.

[0023] See also Figure 1-2In the embodiment of the utility model, the other end of the movable pin 903 is set as an inclined surface, and the inclined surface of the other end of the movable pin 903 matches the inner wall of the push ring 7. When the push ring 7 is pushed toward the metal mesh rubber and plastic tube body 1, the other end of the movable pin 903 releases the extrusion of the inner wall of the push ring 7. At this time, the second reset spring 905 is elastically reset after being stressed, and the limit ring 904 on the surface of the movable pin 903 is pushed to move, so that the other side of the limit ring 904 is close to the inner wall of the movable groove 902. At this time, the inclined surface of the other end of the movable pin 903 moves out of the interior of the movable groove 902, and the lower part of the inclined surface of the movable pin 903 is flush with the end of the movable groove 902. At the same time, one end of the movable pin 903 releases the plugging of the positioning groove 901 on the surface of the fixed ring 3, so as to realize the rapid separation of the metal mesh rubber and plastic tube body 1 and the butt pipe 2, and improve the disassembly efficiency of the metal mesh rubber and plastic tube body 1 and the butt pipe 2.

[0024] Working principle: When the metal mesh rubber-plastic tube body 1 is docked with the butt joint tube 2, the push ring 7 mounted on the surface of the sleeve 4 is pushed, so that the sleeve 4 drives one end of the metal mesh rubber-plastic tube body 1 to move toward the corresponding butt joint tube 2. After the end of the butt joint tube 2 is pressed against the inner wall of the positioning ring 5 on the inner wall of the metal mesh rubber-plastic tube body 1, the push ring 7 is moved toward the butt joint tube 2 by continuing to push the push ring 7. At this time, the inner wall of the push ring 7 squeezes the inclined surface of the other end of the four movable pins 903 at the same time, so that the movable pins 903 move toward the corresponding positioning grooves 901, completing the rapid docking of the metal mesh rubber-plastic tube body 1 and the butt joint tube 2. At the same time, the first reset spring 8 elastically resets the side of the push ring 7 that is always pushed to limit the movement of the push ring 7 When the metal mesh rubber and plastic tube body 1 is disassembled, by pushing the push ring 7 toward the metal mesh rubber and plastic tube body 1, the other end of the movable pin 903 releases the extrusion of the inner wall of the push ring 7, and the second reset spring 905 is elastically reset after being stressed, pushing the limit ring 904 on the surface of the movable pin 903 to move, so that the other side of the limit ring 904 is close to the inner wall of the movable groove 902, and the inclined surface of the other end of the movable pin 903 moves out of the inside of the movable groove 902, and the lower part of the inclined surface of the movable pin 903 is flush with the end of the movable groove 902, and at the same time, one end of the movable pin 903 releases the plug-in connection with the positioning groove 901 on the surface of the fixed ring 3, so as to realize the rapid separation of the metal mesh rubber and plastic tube body 1 and the butt pipe 2.
