The upper connecting hardware 2 and the lower connecting hardware 3 are consistent with the size of ordinary rod-shaped suspension insulators and can be interchangeable. According to the engineering voltage level, multiple connections can be made or a single connection can be used. The insulator of this structure can be used in both tension strings and suspension strings, and has strong bending and torsion resistance and high strength.

The mounting plate 8 is arranged above the mounting seat 6. The mounting seat 6 and the mounting plate 8 are hinged to each other through the rotating shaft 7. The mounting seat 6 and one end of the mounting plate 8 are penetrated by a threaded hole 9. The screw 10 is arranged inside the threaded hole 9. The rotating block 11 is installed at the top of the screw 10. The mounting seat 6 and the mounting plate 8 The inner sides are all designed in an arc shape, and the mounting seat 6 and the mounting plate 8 are symmetrically distributed. When in use, the rotating block 11 is rotated to rotate the screw 10 out of the threaded hole 9 inside the mounting seat 6. At this time, the mounting plate 8 can be lifted up, and then the wire is placed in the groove of the mounting seat 6, and then the mounting plate 8 is covered, and the rotating block 11 is rotated in the opposite direction to rotate the screw 10 to the inside of the threaded hole 9 to complete the fixing of the mounting plate 8. The wire can be conveniently installed, which can make the insulator and the wire more convenient and quick to install and connect, thereby greatly improving the convenience of the insulator when in use.

[0021] The mounting mechanism includes a fixing hole 12, a fixing block 13, a rotating wheel 14, a driving gear 15, a lower transmission rack 16, an upper transmission rack 17 and a limiting structure. The fixing hole 12 is opened on both sides of the upper connecting hardware 2. The fixing hole 12 is provided with a fixing block 13 inside.

One end of the lower transmission rack 16 is connected to the top of one of the fixing blocks 13. The upper part of the driving gear 15 is meshed with an upper transmission rack 17. One end of the upper transmission rack 17 is connected to the top of another fixing block 13. The inner diameter of the fixing hole 12 is larger than that of the fixing block 1 3, a snap-fit ​​structure is formed between the fixing hole 12 and the fixing block 13. When in use, the fixing cavity 5 is placed above the upper connecting hardware 2, and then the rotating wheel 14 is rotated to drive the driving gear 15 to rotate. Since the upper and lower parts of the driving gear 15 are respectively meshed with the lower transmission rack 16 and the upper transmission rack 17, the lower transmission rack 16 and the upper transmission rack 17 are driven to move under the limit of the limit rod 18 and the limit sleeve 19, and then the two fixing blocks 13 are driven to move, and the fixing block 13 is moved to the inside of the fixing hole 12, so that the fixing hole 12 and the fixing block 13 are snap-fitted with each other, completing the convenient installation of the mounting seat 6, and the mounting seat 6 can be conveniently installed, so that the mounting seat 6 can be conveniently installed on any identical upper connecting hardware 2, thereby greatly improving the versatility of the insulator when in use.

[0023] Working principle: The staff first takes out the fixing cavity 5, places the fixing cavity 5 above the upper connecting hardware 2, and then rotates the rotating wheel 14 to drive the driving gear 15 to rotate. Since the upper and lower parts of the driving gear 15 are respectively meshed with the lower transmission rack 16 and the upper transmission rack 17, under the limit of the limit rod 18 and the limit sleeve 19, the lower transmission rack 16 and the upper transmission rack 17 are driven to move, and then the two fixing blocks 13 are driven to move, and the fixing blocks 13 are moved to the inside of the fixing hole 12, so that the fixing hole 12 and the fixing block 13 are engaged with each other. The mounting base 6 is conveniently installed. When in use, the rotating block 11 is rotated to rotate the screw 10 out of the threaded hole 9 inside the mounting base 6. At this time, the mounting plate 8 can be lifted up, and then the wire is placed in the groove of the mounting base 6, and then the mounting plate 8 is covered, and the rotating block 11 is rotated in the opposite direction to rotate the screw 10 to the inside of the threaded hole 9 to complete the fixing of the mounting plate 8.
