Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: an anti-extrusion cable, comprising an outer skin 1 and a first protective layer 2, the first protective layer 2 is arranged in the outer skin 1, the second protective layer 3 is arranged in the first protective layer 2, the third protective layer 4 is arranged in the second protective layer 3, the gaskets 5 are arranged in annular equidistantly in the third protective layer 4, the gaskets 5 are arranged in a supporting assembly, and the gaskets 5 are arranged in a buffer assembly, such as Figure 1 As shown, the device solves the problem that most of the existing related devices mentioned above are that when in use, due to complex environmental factors, the cable may be strongly squeezed from time to time, so that when the device is squeezed externally during use, it is easy to cause the internal wire to be squeezed and deformed, and it is easy to cause the cable rubber sheath to rupture, resulting in the device being unable to maintain normal operation, thus affecting the corresponding work efficiency. In addition, the structure of the device is relatively simple, and it is relatively quick and convenient to use. The device has good practicality, and the production cost is relatively low, which is easy to promote and use.

[0021] Further, the support assembly includes a first protective block 6, a second protective block 7 and a third protective block 8. The first protective block 6 is arranged in the gasket 5, the second protective block 7 is arranged in the first protective block 6, the third protective block 8 is arranged in the second protective block 7, and the inner core 9 is arranged in the second protective block 7. Figure 1and Figure 2 As shown, the structure forms a stable triangle, wrapping the inner core 9 therein, providing comprehensive protection for the inner core 9 and effectively preventing the inner core 9 from being damaged or broken when subjected to strong pressure.

[0022] Further, the buffer assembly includes a fixed rod 10, a piston block 11, a movable groove 12 and a spring body 13. The outer wall of the first protective block 6 is fixedly connected to the fixed rod 10, the fixed rod 10 is fixedly connected to the piston block 11 near the outer skin 1, and the gasket 5 is equidistantly provided with movable grooves 12, and the spring body 13 is arranged in the movable groove 12. Figure 3 and Figure 4 As shown, this structure makes it easy for the piston block 11 on the fixed rod 10 to slide in the movable groove 12 when the outer layer of the gasket 5 is subjected to pressure, so that the spring body 13 is compressed, and the restoring force of the spring body 13 and the friction force generated by the piston block 11 and the inner wall of the movable groove 12 offset each other, so that the device has a certain buffering effect when it is under pressure, further increasing the pressure resistance of the device, and the structure is simple and easy to use.

[0023] Furthermore, the third protective layer 4 is made of an aluminum-plastic composite tape anti-interference material, the second protective layer 3 is made of a fireproof material of a fireproof plastic material, and the first protective layer 2 is made of a rubber waterproof material. Figure 2 As shown, this structure facilitates the device to have better anti-interference, fireproof and waterproof properties, and effectively protects the inner core 9.

[0024] Furthermore, the first protective block 6, the second protective block 7 and the third protective block 8 form a stable triangle, and the sharp angle of the third protective block 8 is sixty degrees. Figure 2 As shown, this structure facilitates better stability of the device, is less likely to cause deformation and shaking, and allows the inner core 9 to maintain normal operation.

[0025] Furthermore, the first protective block 6, the second protective block 7 and the third protective block 8 are made of hard material and are provided with fine air holes therein. Figure 2 As shown, this structure facilitates making the triangle formed by the first protective block 6, the second protective block 7 and the third protective block 8 more stable, and is beneficial to the heat dissipation of the inner core 9, thereby preventing the inner core 9 from being overheated and damaged.

[0026] Furthermore, the outer diameter of the piston block 11 is equal to the inner diameter of the movable groove 12, the outer wall of the piston block 11 is rough, and the gasket 5 is made of soft silicone material, such as Figure 4 As shown, this structure makes the friction between the piston block 11 and the movable groove 12 larger, and enables the piston block 11 to slide stably in the movable groove 12 to prevent position deviation.

[0027] Working principle: When in use, first place the device on a horizontal working surface, then place the inner core 9 in the second protective block 7, and wrap each protective layer precisely from the inside to the outside in sequence. The first protective block 6, the second protective block 7 and the third protective block 8 form a stable triangle to provide firm support and protection for the inner core 9. When the external environment generates a large pressure, the piston block 11 on the fixed rod 10 slides in the movable groove 12 to compress the spring body 13, so that the restoring force of the spring body 13 and the friction force generated by the piston block 11 and the inner wall of the movable groove 12 offset each other, so that the device has a certain buffering effect when under pressure, further increasing the pressure resistance of the device, and the structure is simple, and it is convenient and quick to use. The above is the entire working principle of the utility model.

[0028] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model.
