[0033] In this embodiment, a wear-resistant and collision-resistant composite seamless elastic tube is implemented as follows: an inner tube 2 is placed inside the elastic tube body 1, and the array position of the bending groove 10 is ensured to be reasonable. A stop block 7 is placed at an appropriate position inside the inner tube to ensure that it is in close contact with the wall surface of the inner tube 2 and the positioning groove 12 on the outside thereof is accurately aligned. An elastic strip 11 made of PE material is nested and connected with the embedding groove 13 of the stop block 7, and the elastic strips 11 are ensured to be evenly distributed in a circular array on the outside of the inner tube 2 and staggered with each other. A reinforcing plate 3 made of metal material is clamped with the positioning groove 12 on the outside of the stop block to ensure that it is stable. A waterproof coating is applied to the outside of the inner tube 2 to form a waterproof layer 4. To ensure that the inside of the pipeline is not affected by liquid intrusion, use flexible non-woven fabric to wrap the wrapping layer 5 around the outside of the waterproof layer with reasonable overlap to enhance structural stability. Wrap the braided layer 6 made of metal wire on the outermost layer to provide additional structural strength and protection for the pipeline. Finally, wrap the sheath 9 around the outside of the entire pipeline and ensure that the buffer groove 8 set in its annular array is in the appropriate position to reduce external impact. Regularly inspect and maintain the elastic tube according to usage, and replace worn parts in time to extend its service life.

[0034] like Figure 1-5 As shown, the inner tube 2 is provided with a bending groove 10 in an array inside, a limiting block 7 is provided at an internal position of the inner tube 2, an embedding groove 13 is provided at an inner position of the limiting block 7, an elastic strip 11 is provided at an inner position of the embedding groove 13, the elastic strip 11 is nested and connected with the embedding groove 13, and the elastic strip 11 is made of PE material, a positioning groove 12 is provided at an outer position of the limiting block 7, a reinforcing plate 3 is provided at an inner position of the positioning groove 12, the reinforcing plate 3 is snap-connected with the positioning groove 12, the reinforcing plate 3 is made of metal material, the reinforcing plate 3 and the elastic strip 11 are arranged in a ring array on the outside of the inner tube 2, and the elastic strips 11 are staggered with each other.

[0035] Preferably, the elastic strip made of PE material has good wear resistance, thereby effectively extending the service life of the inner tube and reducing wear. The elastic strip 11 is arranged in a surrounding manner, covering the entire outer side of the inner tube, increasing the force-bearing area and further improving the wear resistance. The structural design between the limit block 7 and the elastic strip 11 can effectively absorb external impact force, reduce the direct impact of external force on the pipeline, and reduce the risk of damage.

The braided layer 6 is woven using metal wire and has strong mechanical strength and wear resistance. It provides additional support for the entire pipeline, enhances the pipeline's compressive and tensile strength, and effectively prevents deformation or rupture under high pressure or external force. The presence of the braided layer can help disperse external shocks and vibrations. When the pipeline is subjected to external force, it can effectively reduce the impact on the inner tube and protect the inner tube from damage.
