Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a modular disc insulator, including umbrella portion 1, axial region 2, connecting portion 3, cover member 4 and connecting hole 5, cover member 4 is located umbrella portion 1's top, connecting hole 5 is located cover member 4's inside top, axial region 2 is fixed in umbrella portion 1's inside, connecting portion 3 is installed in axial region 2's one end, mounting groove 6 has been seted up to cover member 4's inside, stopper 8 is installed to 6 inner walls of mounting groove, stopper 8 extends to connecting hole 5's inside, be provided with spring 9 between the inner wall of stopper 8 and mounting groove 6, can support stopper 8 through spring 9.

Furthermore, a sealing ring 12 is installed on the inner wall of the umbrella part 1, a bulge 13 is arranged on one side of the sealing ring 12, and the bulge 13 can increase the insulation property of the sealing ring 12.

Furthermore, a spring rod 10 is arranged between the spring 9 and the limiting block 8, the spring 9 and the limiting block 8 are connected with each other through the spring rod 10, and therefore the shift piece 7 can be used for conveniently driving the spring rod 10 to move by workers.

Specifically, the shifting piece 7 is installed at the top of the spring rod 10, the shifting piece 7 is connected with the inner wall of the installation groove 6 in a sliding mode, and the connecting portion 3 can be detached through the shifting piece 7.

It is worth to say that, the connecting portion 3 is provided with a limiting hole 11 inside, and the limiting hole 11 is matched with the limiting block 8, so that the connecting portion 3 can be effectively connected.

Furthermore, the sealing ring 12 is positioned on the outer surface of the shaft part 2, and the shaft part 2 penetrates through the sealing ring 12, so that the stability of the shaft part 2 can be effectively improved.

The utility model discloses a theory of operation and use flow: when the utility model is used, the shaft part 2 inside the umbrella part 1 is connected with the cover part 4 through the connecting part 3, when the connecting part 3 is put into the connecting hole 5 in the cover part 4, the connecting part 3 pushes the stopper 8 to move towards the inside of the mounting groove 6, and simultaneously the spring 9 pushes the stopper 8 to enter the stopper hole 11 in the connecting part 3, thereby fixing the connecting part 3;
