[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: a flame-retardant elastic rubber and plastic corrugated insulation pipe, which includes an outer pipe 1 and an inner pipe 2. The inner pipes 2 are connected by splicing and are cooperatively sealed with a special glue. The flame-retardant layer 5 is made of a silicon-based compound. The right side of the outer pipe 1 is fixedly connected to the tail end of the clamping block 15, and the left side inside the outer pipe 1 is fixedly connected to the tail of the second spring 17. And above the second spring 17 is fixedly connected to the blocking block 16. The inside of the outer pipe 1 is connected to the corrugated layer 3 through a buffer mechanism. The buffer mechanism includes a connecting rod 7, a moving plate 8, and a first spring 9. Above the connecting rod 7 is fixedly connected to the bottom of the corrugated layer 3, and below the connecting rod 7 is fixedly connected to the moving plate 8. And the moving plate 8 is connected to the inside of the outer pipe 1 through a sliding connection. Below the moving plate 8 is fixedly connected to the upper part of the first spring 9, and below the first spring 9 is fixedly connected to the inside of the outer pipe 1. The first spring 9 is symmetrically arranged about the center of the moving plate 8, and the upper parts of the first spring 9 are all fixedly connected to the bottom of the moving plate 8. And the material of the first spring 9 is metal. And on the surface of the corrugated layer 3 is provided a fireproof layer 4, and inside the corrugated layer 3 is provided a flame-retardant layer 5. Below the corrugated layer 3 is fixedly connected to the upper part of the moving rod 6, and the lower end of the moving rod 6 is connected to the inside of the outer pipe 1 through a sliding connection. And on the surface of the moving rod 6 is provided a limiting block;

[0027] First, when in use, after connecting the outer pipe 1 and the inner pipe 2 through the adhesive layer 14, a certain number of insulation pipes are taken out according to the length of the pipeline to be laid. At this time, the clamping block 15 on the right side of the outer pipe 1 is aligned with the card slot on the left side of other outer pipes 1 and pressed in. At the same time, the inner pipes 2 are directly inserted and cooperatively sealed with glue for connection. At this time, the clamping block 15 and the blocking block 16 connected to the inside of the outer pipe 1 through the second spring 17 are engaged to complete the connection. At the same time, when in use, the rubber material corrugated layer 3 on the surface of the outer pipe 1 has a certain elasticity. At the same time, when the corrugated layer 3 is impacted, the corrugated layer 3 drives the moving plate 8 to move in the sliding groove inside the outer pipe 1 through the connecting rod 7. At the same time, the first spring 9 below the moving plate 8 is compressed, and at the same time drives the moving rod 6 to move in the sliding groove inside the outer pipe 1 to buffer the corrugated layer 3. At the same time, the elasticity of the corrugated layer 3 can be improved.

At the same time, when in use, the desiccants in the internal drying cavity 12 can keep the inside dry. Since the waterproof layer 13 in the outer pipe 1 can prevent the outer pipe 1 from being damaged when the inner pipe 2 leaks.

[0030] Working principle: When using the flame-retardant elastic rubber and plastic corrugated insulation pipe, first connect the outer pipe 1 and the inner pipe 2 through the adhesive layer 14 during use. Then, take out a certain number of insulation pipes according to the length of the pipeline to be laid. At this time, align the block 15 on the right side of the outer pipe 1 with the slot on the left side of other outer pipes 1 and press it in. At the same time, directly insert and connect the inner pipes 2 with the cooperation of sealing glue. At this time, the block 15 and the stopper 16 connected by the second spring 17 inside the outer pipe 1 are engaged to complete the connection. At the same time, during use, the rubber corrugated layer 3 on the surface of the outer pipe 1 has a certain elasticity. When the corrugated layer 3 is subjected to an impact, the corrugated layer 3 drives the moving plate 8 to move in the chute inside the outer pipe 1 through the connecting rod 7. At the same time, the first spring 9 below the moving plate 8 is compressed, and at the same time, it drives the moving rod 6 to move in the chute inside the outer pipe 1 to buffer the corrugated layer 3, and at the same time, it can improve the elasticity of the corrugated layer 3. The fireproof layer 4 on the surface of the corrugated layer 3 and the flame-retardant layer 5 inside can effectively prevent fires. At the same time, the insulation layer 10 in the outer pipe 1 can have a certain heat insulation effect, and the reinforcing layer 11 inside can increase the strength of the outer pipe 1 to prevent tearing. At the same time, during use, the desiccant in the internal drying cavity 12 can keep the inside dry. Since the waterproof layer 13 in the outer pipe 1 can prevent the outer pipe 1 from being damaged when the inner pipe 2 leaks.
