[0003] The above technical solution forms a diamond-shaped support frame through four upper support rods and four lower support rods, which can support the stability of the porcelain insulator and avoid the situation where the porcelain insulator is bent and deformed and affects its use; by controlling the hook to disengage or insert into the plug-in slot, controlling the circular column to disengage or install on the steel foot, the porcelain insulator can be disassembled or installed, the operation is simple, and the disassembly and installation efficiency of the porcelain insulator is improved. However, when installing and disassembling, the steel foot needs to be disassembled together. When the insulator needs to be replaced, the insulator often needs to be reinstalled to the original position. In this way, for the completely disassembled insulator, it is difficult to install it to the original position when reinstalling it, and the whole process requires the disassembly and installation of the steel foot. Due to its material, the weight burden of the steel foot is relatively large. Utility Model Content

[0024] See also Figure 1-4 , the utility model provides a technical solution: a spliced ​​porcelain insulator steel foot, including a core rod 4 and a steel foot assembly;

[0025] The steel foot assembly is arranged at the bottom of the core rod 4, and the steel foot assembly includes a steel foot base 5, a groove 6, a limit plate 7, three threaded holes 1 8, two clamping plates 9, a limit groove 10, a T-shaped connecting piece 11, three threaded holes 2 12, three threaded holes 3 13, three threaded columns 14 and three rotating parts 15.

[0026] The groove 6 is formed inside the steel foot base 5 , and the T-shaped connector 11 slides along the inside of the groove 6 .

[0027] The three threaded holes 1 8 are all formed on the limiting plate 7 , and the three threaded holes 2 12 are all formed on the T-shaped connecting piece 11 .

[0028] Three threaded holes 13 are all formed on the steel foot base 5 , and three rotating members 15 are respectively welded to corresponding threaded columns 14 .

[0029] The surfaces of the three threaded columns 14 are respectively threadedly connected to the inner surfaces of the corresponding threaded holes 3 13 , the surfaces of the three threaded columns 14 are respectively threadedly connected to the inner surfaces of the corresponding threaded holes 2 12 , and the surfaces of the three threaded columns 14 are respectively threadedly connected to the inner surfaces of the corresponding threaded holes 1 8 .

[0030] A plurality of composite sheds 3 are fixedly mounted on the core rod 4 , a fixing seat 2 is threadedly connected to the upper end of the core rod 4 , and a wire clamping groove 1 is provided on the surface of the fixing seat 2 .

[0031] When it is necessary to install the porcelain insulator;

[0032] First, the steel foot base 5 is driven to move by an external force, and the movement of the steel foot base 5 drives the two clamping plates 9 to move to the position where they need to be installed and fixed.

[0033] Secondly, the composite umbrella skirt 3 is driven to move by an external force, the movement of the composite umbrella skirt 3 drives the core rod 4 to move, the movement of the core rod 4 drives the T-shaped connector 11 to move along the inside of the groove 6, and the movement of the T-shaped connector 11 drives the limiting groove 10 to move along the surface of the limiting plate 7 until the threaded hole 1 8 coincides with the corresponding threaded hole 2 12, and the threaded hole 2 12 coincides with the corresponding threaded hole 3 13.

[0034] Finally, the three rotating members 15 are driven to move by an external tool, and the movement of the three rotating members 15 drives the corresponding threaded columns 14 to move to the inside of the corresponding threaded hole three 13 , threaded hole two 12 and threaded hole one 8 .

[0035] By setting two clamping plates 9 in the steel foot assembly, the steel foot base 5 is fixed at the position to be installed by the two clamping plates 9. When it is necessary to disassemble and replace the insulator, the core rod 4 can be replaced only by disassembling the three rotating parts 15. The steel foot base 5 does not need to be disassembled during the whole process. This not only reduces the weight when replacing the insulator and reduces the difficulty of replacement, but also provides a position for the insulator to be installed again, thereby avoiding the problem of finding the position caused by the need to reinstall it back to the original position, that is, reducing the difficulty of replacing the insulator.

[0036] By setting the T-shaped connector 11 to be T-shaped, the T shape can be stuck inside the groove 6 to prevent the T-shaped connector 11 from shaking up and down, and the connection between the limit plate 7 and the limit groove 10 can prevent the T-shaped connector 11 from rotating, and the three threaded columns 14 can improve the forward and backward movement stability of the T-shaped connector 11.

[0037] Working principle:

[0038] When it is necessary to install the porcelain insulator;

[0039] First, the steel foot base 5 is driven to move by an external force, and the movement of the steel foot base 5 drives the two clamping plates 9 to move to the position where they need to be installed and fixed.

[0040] Secondly, the composite umbrella skirt 3 is driven to move by an external force, the movement of the composite umbrella skirt 3 drives the core rod 4 to move, the movement of the core rod 4 drives the T-shaped connector 11 to move along the inside of the groove 6, and the movement of the T-shaped connector 11 drives the limiting groove 10 to move along the surface of the limiting plate 7 until the threaded hole 1 8 coincides with the corresponding threaded hole 2 12, and the threaded hole 2 12 coincides with the corresponding threaded hole 3 13.

[0041] Finally, the three rotating members 15 are driven to move by an external tool, and the movement of the three rotating members 15 drives the corresponding threaded columns 14 to move to the inside of the corresponding threaded hole three 13 , threaded hole two 12 and threaded hole one 8 .
