DETAILED DESCRIPTION

[0018] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Figure 1As an embodiment of the utility model, a pressure-resistant cable comprises an outer sheath 1, a waterproof layer 2, a reinforcing steel wire 6, a cable core 8 and a fireproof filler 9, and also comprises a buffer layer 3, a pressure-resistant bracket 4, a supporting filler 5 and an arc block 7. A reinforcing steel wire 6 is installed in the center of the pressure-resistant bracket 4. The pressure-resistant bracket 4 is provided with a plurality of placement grooves 1 41, a placement groove 2 42 and a plurality of placement grooves 3 43 from the outside to the inside. A cable core 8 is arranged inside the placement groove 3 43. A fireproof filler 9 is arranged between the placement groove 3 43 and the cable core 8. A supporting filler 5 is arranged inside the placement groove 2 42. An array of mutually cooperating arc blocks 7 is arranged on the side wall of the placement groove 2 42. The supporting filler 5 arranged inside the placement groove 2 42 is provided with a plurality of movable cavities 72 cooperating with the arc blocks 7. A supporting filler 5 is arranged inside the placement groove 1 41. A buffer layer 3 is arranged on the outer wall of the pressure-resistant bracket 4. A waterproof layer 2 is arranged on the outer side of the buffer layer 3. An outer sheath 1 is arranged on the outer side of the waterproof layer 2.

[0020] The outer sheath 1 is used to protect the entire cable, the waterproof layer 2 plays a waterproof role, ensuring the waterproofness of the device during use, and the buffer layer 3 plays a preliminary buffering role when the device is under pressure. The compression bracket 4 increases the overall strength of the device, thereby increasing the compression resistance of the cable and reducing the damage to the cable core 8 during the cable being squeezed. The outer wall shape of the compression bracket 4 is arc-shaped, which ensures the working effect of the compression bracket 4. Figure 2As shown, the compression bracket 4 is provided with a plurality of placement grooves 41 in an annular shape, the center of the ring formed by the plurality of placement grooves 41 overlaps with the center of the compression bracket 4, the positions of the placement grooves 41 ensure that the shapes of the placement grooves 41 are the same, thereby ensuring that the working effects of the placement grooves 41 are the same, the placement grooves 41 are evenly distributed on the compression bracket 4, ensuring that the widths of the compression bracket 4 between adjacent placement grooves 41 are the same, and the portion of the compression bracket 4 located between the placement grooves 41 plays a role in supporting the placement grooves 41. The inner and outer arc-shaped side walls ensure the strength of the part of the compression support 4 where the placement groove 1 41 is set. The placement grooves 3 43 are evenly distributed in an annular manner on the compression support 4, ensuring that the strengths of the placement grooves 3 43 are the same. The placement grooves 3 43 are set in a manner that ensures that the supporting capacity of the compression support 4 between the placement grooves 3 43 is the same, ensuring that the strengths of each position of the compression support 4 are the same. The support fillers 5 set inside the placement grooves 1 41 and the placement grooves 2 42 play a role in supporting the placement grooves 1 41 and the placement grooves 2 42. The overall compressive strength of the cable is ensured. The arc block 7 arranged on the placement groove 42 plays a role in supporting the placement groove 42. When the cable is squeezed, the placement groove 42 is deformed. The deformed placement groove 42 will squeeze the arc block 7. The deformed arc block 7 plays the role of reducing the deformation amplitude of the placement groove 42, thereby ensuring the compressive strength of the cable. The shape of the arc block 7 is an arc, which ensures the working effect of the arc block 7. The movable cavity 72 is used to accommodate the arc block 7. The shape of the movable cavity 72 ensures The deformation of the arc block 7 will not be hindered, thereby ensuring the working effect of the arc block 7. The deformed moving cavity 72 plays a buffering role, thereby ensuring the working effect of the pressure-resistant bracket 4. The fireproof filler 9 arranged on the placement groove three 43 plays a role of supporting the placement groove three 43. The fireproof filler 9 also plays a fireproof role, thereby preventing the cable core 8 from burning during the use of the device, thereby ensuring the safety of the cable. The cable core 8 is used for the transmission of electric energy. The reinforcing steel wire 6 arranged in the center of the pressure-resistant bracket 4 improves the tensile resistance of the cable.

[0021] Specifically, Figure 4As shown, a plurality of connecting wires 71 are provided between the matching arc blocks 7 to connect the matching arc blocks 7, and the connecting wires 71 have a certain elasticity. The two matching arc blocks 7 are in a symmetrical state. When the arc block 7 is deformed due to the compression of the compression-resistant bracket 4, the two matching arc blocks 7 move in opposite directions when deformed. When the arc block 7 is deformed, the connecting line 71 connecting the two arc blocks 7 is deformed under the pull of the deformed arc block 7. The deformed connecting line 71 plays a role in blocking the arc block 7, thereby improving the working effect of the arc block 7. The connecting line 71 is elastic, thereby ensuring that when the arc block 7 is restored to its original state, the connecting line 71 is restored to its original state together with the arc block 7, thereby ensuring the working effect of the arc block 7 and the connecting line 71. The elastic connecting line 71 can also prevent the connecting line 71 from being broken during the deformation of the arc block 7, thereby ensuring the working effect of the connecting line 71. By setting a number of connecting lines 71 connecting the matching arc blocks 7, the working effect of the connecting line 71 is ensured.

[0022] Specifically, a plurality of reinforcing steel wires 6 are arranged inside the supporting filler 5 arranged on the placement slot 1 41. The plurality of reinforcing steel wires 6 arranged in the supporting filler 5 arranged on the placement slot 1 41 increase the compressive and tensile strength of the supporting filler 5 arranged in the placement slot 1 41, and ensure the working effect of the supporting filler 5 arranged in the placement slot 1 41. The shape of the placement slot 1 41 ensures that the shapes of the supporting fillers 5 arranged in the placement slot 1 41 are the same, and ensures that the working effects of the supporting fillers 5 in each placement slot 1 41 are the same.

[0023] Regarding the buffer layer 3, Figure 3 As shown, a reinforcing net 31 is provided inside, and the reinforcing net 31 is in the shape of a mesh. The mesh reinforcing net 31 improves the compression resistance of the buffer layer 3 while improving the overall strength of the buffer layer 3, thereby ensuring the working effect of the reinforcing net 31. In addition, a connecting layer 32 connecting the compression-resistant bracket 4 and the buffer layer 3 is provided on the inner wall of the buffer layer 3. The connecting layer 32 can fix the buffer layer 3 on the outer wall of the compression-resistant bracket 4, and the connecting layer 32 ensures the stability of the connection between the compression-resistant bracket 4 and the buffer layer 3, thereby preventing the connection between the buffer layer 3 and the compression-resistant bracket 4 from failing when the cable is squeezed, thereby ensuring the stability of the overall structure of the cable after being squeezed.

[0024] Regarding the cable core 8, an insulating layer and an isolation layer are provided on its outer side from the inside to the outside. The insulating layer can prevent the working ability of the cable core 8 from being affected, thereby ensuring the working effect of the cable. The isolation layer provided on the outer side of the cable core 8 can separate the cable core 8 and the fireproof filler 9, thereby ensuring that the fireproof filler 9 will not affect the cable core 8.

[0025] Based on the compression-resistant cable of the aforementioned structure, when the cable is subjected to pressure, the buffer layer 3 and the reinforcing net 31 will buffer the pressure exerted on the cable, and then the compression-resistant bracket 4 is subjected to pressure, and the placement groove 1 41 and the placement groove 2 42 are deformed, and the supporting filler 5 plays a role in supporting the placement groove 1 41 and the placement groove 2 42, reducing the deformation amplitude of the placement groove 1 41 and the placement groove 2 42, and when the placement groove 2 42 is deformed, the placement groove 2 42 will squeeze the arc block 7, and the arc block 7 is deformed under the action of the placement groove 2 42, and the deformed arc block 7 plays a buffering role, further reducing the force exerted on the cable core 8, and as the arc block 7 is deformed, the corresponding arc block 7 moves in the opposite direction, and the connecting line 71 arranged on the corresponding arc block 7 is elastically deformed under the stretching of the deformed arc block 7, and the connecting line 71 hinders the deformation of the arc block 7, reducing the deformation amplitude of the arc block 7, thereby improving the working effect of the arc block 7.
