[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-Figure 5 The utility model discloses an shed type composite insulator, including a core rod 10. The core rod 10 is made of a composite material, composed of glass fiber and epoxy resin. A limit assembly 20 is provided on the top surface of the core rod 10. A slot 30 is provided in the middle of the bottom end of the core rod 10. A threaded interface 40 is provided in the middle of the top surface of the slot 30. A connecting assembly 50 is provided at the bottom end of the core rod 10 and is threadedly connected to the threaded interface 40. The core rod 10 is sleeved with a plurality of sheds 60 distributed up and down. Adjacent sheds 60 fit tightly together. The designed sheds 60 can make the adjacent sheds 60 fit tightly together, and the fitting surface is large, thereby greatly improving the sealing performance.
[0021] The top surface of the first mounting seat 51 is integrally connected with a first sealing sleeve 52, and the middle portion of the bottom end of the first mounting seat 51 is provided with a groove 53, which can serve as a storage. The middle portion of the top surface of the groove 53 is provided with an opening 54, and a gasket 55 is clamped in the groove 53. The middle portion of the top surface of the gasket 55 is integrally connected with a clamping column 56, and the bottom end of the gasket 55 is provided with a fixing bolt 57, which passes through the opening 54 and is clamped in the clamping groove 30. The cross-sections of the clamping groove 30 and the clamping column 56 are both regular hexagonal structures. The upper end of the fixing bolt 57 is threadedly connected to the threaded interface 40 to play a role of fixed connection. The cross-sections of the groove 53 and the gasket 55 are both square structures. The first sealing sleeve 52 is inserted into the lowest umbrella skirt 60, and the upper portion of the outer wall of the first sealing sleeve 52 is in contact with the inner wall of the lowest umbrella skirt 60 to play a sealing role.
[0022] In this embodiment, when it cooperates with the limiting assembly 20, multiple umbrella skirts 60 are located between the limiting assembly 20 and the connecting assembly 50, and the multiple umbrella skirts 60 can be fixedly installed. When the damaged umbrella skirt 60 needs to be replaced, it is only necessary to reverse the fixing bolt 57. By removing the fixing bolt 57, the entire connecting assembly 50 can be removed, and then the umbrella skirt 60 on the core rod 10 can be removed, which is very convenient for replacement.

[0024] In this embodiment, the movement of the shed 60 is restricted, and the uppermost shed 60 is tightly inserted into the second sealing sleeve 22, with a tight connection and good sealing performance.
[0025] The installation steps of the umbrella skirt 60 are as follows: turn the core rod 10 upside down so that the entire limit assembly 20 faces downward, and put the umbrella skirts 60 on the core rod 10 one by one. At this time, the two adjacent umbrella skirts 60 are tightly fitted, and the outer wall of the first umbrella skirt 60 is tightly fitted on the inner wall of the second sealing sleeve 22. When all the umbrella skirts 60 are fully placed, the clamping column 56 is passed through the opening 54, the gasket 55 is embedded in the groove 53, the clamping column 56 is clamped in the clamping slot 30, and the fixing bolt 57 is installed so that the fixing bolt 57 is threadedly connected to the threaded interface 40 on the core rod 10.
