However, the existing corrosion-resistant, impact-resistant and flame-retardant PVC cable pipe lacks a structure for protecting cable wires, resulting in the cable wires being easily broken after being impacted, which is not conducive to the long-term use of cable wires. Summary of the Utility Model

[0005] The utility model provides a corrosion-resistant and impact-resistant PVC cable material, aiming to solve the problem that the existing corrosion-resistant, impact-resistant and flame-retardant PVC cable pipe lacks a structure for protecting cable wires, resulting in the cable wires being easily broken after being impacted, which is not conducive to the long-term use of cable wires.

[0006] The utility model is realized as follows. A corrosion-resistant and impact-resistant PVC cable material includes a cable pipe and a protection mechanism, and the protection mechanism is snap-connected to the inside of the cable pipe;

[0007] The protection mechanism includes a protection tube, a cable hole, a reinforcing rib, and a buffer plate. The protection tube is clamped inside the cable tube. The cable hole is opened inside the protection tube. The reinforcing rib is bolted inside the protection tube. The buffer plate is bolted inside the cable hole.

The protection pipe can support and limit the cable holes, reinforcing ribs and buffer plates, and has good corrosion resistance itself, being able to effectively resist the erosion of external chemical substances, ensuring the long-term stable operation of the internal cables in harsh environments. The setting of the cable holes provides an orderly layout space for the cables, avoiding the chaotic entanglement between the cables and improving the cable sorting and maintenance efficiency. The reinforcing ribs are bolted to the inner side of the protection pipe, greatly enhancing the structural strength of the protection pipe, enabling it to withstand greater external force impacts and effectively preventing the protection pipe from deforming or being damaged when impacted or squeezed, thus better protecting the internal cables. The buffer plate is bolted to the inner side of the cable hole and is of a negative Poisson's ratio type. This unique structural design enables the buffer plate, when impacted, not only to effectively absorb and disperse the impact force, but also its lateral expansion characteristic can increase the contact area with the cables, providing a more uniform buffering effect, thus significantly reducing the risk of the cables being damaged due to vibration or impact. Even under strong impact, the negative Poisson's ratio type buffer plate can maintain good buffering performance, thus providing continuous and reliable protection for the cables, buffering the impact after the cable is impacted and reducing the damage caused by the impact, thereby extending the service life of the cable.

[0042] Working principle: First, the user snaps the cable onto the inner side of the wire fixing ring 4 to fix the cable through the wire fixing ring 4. Then, the user snaps the protective tube 201 onto the inner side of the cable tube 1 and buries the cable tube 1. After that, when the cable tube 1 is impacted, the protective pad 3 can fill the gap between the cable tube 1 and the protective tube 201, playing a buffering and shock-absorbing role, reducing the direct friction and collision between the two. The porous foam structure of the protective pad 3 greatly improves the energy absorption and buffering performance, enabling it to better cope with external impacts and vibrations, protecting the internal cable from direct external impacts and chemical erosion. The protective tube 201 is snapped onto the inner side of the cable tube 1 to absorb and release the impact. The reinforcing rib 203 enhances the structural strength of the protective tube 201, enabling it to withstand greater external force impacts and preventing deformation and damage when being hit or squeezed. The buffer plate 204 is of negative Poisson's ratio type and can effectively absorb and disperse the impact force when being impacted. Its lateral expansion characteristic can also increase the contact area with the cable, providing a more uniform buffering effect. Finally, the user can repair the impacted cable tube 1 with the repair ring 5.
