SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the high-strength electric porcelain insulator is beneficial to improving the rainproof performance of a high-low voltage switch cabinet. And effective utilization.

In order to solve the technical problem, the utility model adopts a technical proposal that; the utility model provides a high strength electric power porcelain insulator, includes two structures of center pin, porcelain full skirt structure and porcelain full skirt, a porcelain full skirt structure cover is established on the center pin, two structure cover of porcelain full skirt are established on the center pin, a porcelain full skirt structure is contradict the setting with two structures of porcelain full skirt, a porcelain full skirt structure includes porcelain full skirt one and connecting block one, two structures of porcelain full skirt include porcelain full skirt two and connecting block two, the one end of center pin is equipped with fixed line hole, the one end connection that the center pin is close to fixed line hole is equipped with connecting block three, be equipped with quantity on the connecting block three and be no less than four screw holes, be equipped with fixed screw on the screw hole, be equipped with fixation nut one on the fixed screw, the one end that the connecting block was kept away from to the center pin is equipped with fixation nut two.

Furthermore, the circumferential diameter of the first ceramic umbrella skirt is larger than that of the second ceramic umbrella skirt.

Furthermore, the central shaft is provided with threads.

Furthermore, internal threads are arranged in the first ceramic umbrella skirt and the first connecting block, and internal threads are arranged in the second ceramic umbrella skirt and the second connecting block.

Furthermore, the third connecting block is in threaded connection with the central shaft.

The utility model has the advantages that; the electric wire can be fixed better in the fixed line hole of center pin one end, porcelain full skirt one and porcelain full skirt two have guaranteed the creepage distance of insulator, the size in space between porcelain full skirt one and the porcelain full skirt two has also been increased, prevent that the dust from piling up, porcelain full skirt one and porcelain full skirt two that can separate, with the comparison of traditional integral type before, even partial part takes place to damage and also need not all to change and only need remove other parts to the part that corresponds the damage and still can use as usual, the loss of property has been reduced.

Detailed Description

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1-3, a high-strength electric porcelain insulator comprises a central shaft 1, a porcelain umbrella skirt structure I and a porcelain umbrella skirt structure II, the porcelain umbrella skirt structure is sleeved on the central shaft 1, the first porcelain umbrella skirt structure and the second porcelain umbrella skirt structure are arranged in a butting mode, the first porcelain umbrella skirt structure comprises a first porcelain umbrella skirt 3 and a first connecting block 2, the second porcelain umbrella skirt structure comprises a second porcelain umbrella skirt 5 and a second connecting block 4, one end of the central shaft 1 is provided with a fixed wire hole 6, one end of the central shaft 1 close to the fixed wire hole 6 is connected with a third connecting block 7, the third connecting block 7 is provided with at least four threaded holes 11, the threaded hole 11 is provided with a fixing screw 8, the fixing screw 8 is provided with a first fixing nut 9, and one end, away from the third connecting block 7, of the central shaft 1 is provided with a second fixing nut 10.
