[0003] The existing cable fixing frame can expose the cable by moving the slide plate above the cable, which is convenient for repairing the damaged part of the cable. For example, Chinese patent application No. CN202322201431.1 discloses a cable fixing frame for an offshore oil platform, including a lower shell, a baffle is fixedly installed inside the lower shell, a first arc groove is opened inside the lower shell between two groups of baffles and between the baffle and the lower shell, a fixing block is fixedly installed on the top of the lower shell, a connecting block is fixedly installed on the top of the baffle, and a cable fixing device is arranged between the two groups of connecting blocks and between the connecting block and the fixing block.

[0004] After the sliding plate is moved to expose the cable, the cable is still located at the lower side between the two baffles. The baffles may hinder maintenance personnel from repairing the cable, and the surrounding cables may hinder the maintenance process. Utility Model Content

[0026] During operation, the screw rod 9 is rotated to increase the height of the screw rod 9, and the lower end of the screw rod 9 will be disengaged from the lower thread 8. At this time, only the screw hole 6 on the pressure plate 4 and the screw hole 6 on the clamping plate 3 are threadedly connected with the screw rod 9. The threaded rod 10 is rotated to increase the height of the clamping plate 3. The clamping plate 3 drives the cable, the pressure plate 4, and the screw rod 9 to rise, so that the height of the cable is staggered with the surrounding cables. The screw 9 is rotated to continue to increase the height of the screw rod 9, so that the screw 9 is disengaged from the screw hole 6 on the clamping plate 3. At this time, only the screw hole 6 on the pressure plate 4 is threadedly connected with the screw 9. The screw 9 is directly removed, so that the pressure plate 4 is removed, which is convenient for repairing the cable.

[0027] See also Figure 1-5 The utility model provides a technical solution: connecting rods 11 are symmetrically connected to both sides of the upper surface of the base 1 longitudinally, and the upper ends of the corresponding two connecting rods 11 are connected to the same support rod 12, and the support rod 12 is located between the two fixed seats 2.

[0028] During operation, the support rod 12 can support the lower side of the cable, so that the portion of the cable between the two fixing seats 2 is not prone to bending.

[0029] See also Figure 1-5 The utility model provides a technical solution: a rubber sheet is provided on the surface of the opening 5, and an anti-slip pattern is provided on the surface of the rubber sheet.

[0030] During operation, the friction between the opening 5 and the cable can be increased by setting the rubber sheet, which is beneficial for the clamping plate 3 and the pressing plate 4 to clamp and fix the cable.

[0031] See also Figure 1-5 The utility model provides a technical solution: a sprocket is provided on the lower side of the outer surface of the threaded rod 10 , and the outer surfaces of the two corresponding sprockets are meshed with the same chain 13 , and the chain 13 is located inside the base 1 .

[0032] During operation, when one of the threaded rods 10 is rotated, the corresponding sprocket will drive the chain 13 to rotate, and the chain 13 will drive another sprocket to rotate, so that the other threaded rod 10 rotates, so that the two threaded rods 10 rotate at the same time, thereby raising or lowering the height of the splint 3.

[0033] See also Figure 1-5 The utility model provides a technical solution: a sealing ring 14 corresponding to the position of the threaded rod 10 is connected to the upper surface of the base 1 , and the threaded rod 10 passes through the sealing ring 14 .

[0035] See also Figure 1-5 The utility model provides a technical solution: the support rod 12 is made of stainless steel.

[0036] During operation, the stainless steel material has good corrosion resistance and strength, which is conducive to the long-term use of the support rod 12, and the support rod 12 is not easy to deform.

[0037] See also Figure 1-5 The utility model provides a technical solution: the upper end of the screw rod 9 is connected with a handle block 15.

[0038] During operation, the handle block 15 can be held by hand to remove the screw rod 9 and the pressing plate 4.

[0039] In summary, rotating the screw rod 9 will increase the height of the screw rod 9, and the lower end of the screw rod 9 will disengage from the lower thread 8. At this time, only the screw hole 6 on the pressure plate 4 and the screw hole 6 on the clamping plate 3 are threadedly connected to the screw rod 9. Rotating the threaded rod 10 will cause the corresponding sprocket to drive the chain 13 to rotate, and the chain 13 will drive another sprocket to rotate, causing another threaded rod 10 to rotate, thereby driving the clamping plate 3 to increase in height. The clamping plate 3 drives the cable, the pressure plate 4, and the screw rod 9 to rise, so that the cable is staggered in height with the surrounding cables. Rotating the screw 9 will continue to increase the height of the screw 9, so that the screw 9 will disengage from the screw hole 6 on the clamping plate 3. At this time, only the screw hole 6 on the pressure plate 4 is threadedly connected to the screw 9. The screw 9 can be directly removed, so that the pressure plate 4 can be removed, which is convenient for repairing the cable.
