Abstract
Description
Technical Field
[0001] The invention relates to the technical field of insulator iron caps, and in particular to a waterproof and dustproof insulator iron cap. Background Art
[0002] For the currently used disc insulators, whether they are ordinary porcelain or glass disc insulators or composite suspension insulators, the connecting parts between the insulators are mainly iron caps and their matching steel feet, which have been standardized and used all the time. Summary of the invention
[0003] Based on the technical problems existing in the background technology, the present invention proposes a waterproof and dustproof insulator iron cap.
[0004] The invention provides a waterproof and dustproof insulator iron cap, comprising: a lower cap, an upper cap, a rod part and an umbrella part;
[0005] The lower cap is an inverted barrel-shaped structure, and the upper cap is installed on the lower cap. The upper cap has a cavity inside, and a rod hole is opened on the top. The upper cap has a slot connecting the inner cavity and the rod hole. The junction between the slot and the upper cap wall is a trumpet shape that is narrow at the top and wide at the bottom.
[0006] The rod is in the shape of a trumpet that is narrow at the top and wide at the bottom, and matches the slot; the rod is provided with an external thread, and the distance between the external thread and the bottom of the rod is less than the depth of the inner cavity of the upper cap; a through hole is provided in the middle of the umbrella, and an internal thread matching the external thread is provided in the through hole.
[0007] Preferably, it also includes a limiting plate, which is installed on the lower cap through a spring and is located in the inner cavity of the upper cap, and the spring and the limiting plate are both made of conductive metal.
[0008] Preferably, the upper cap is a rounded structure.
[0009] Preferably, the lower cap is a rounded structure.
[0010] Preferably, the umbrella portion covers the upper cap.
[0011] Preferably, the bottom end of the rod is an elliptical surface, and the limiting plate is provided with a groove matching the bottom end of the rod.
[0012] In the present invention, the rod can be inserted into the upper cap through the notch, and the top end of the rod extends out of the rod hole; then, the rod is moved upward in the upper cap to prevent the rod from falling out of the notch. The umbrella and the rod can be connected by threads. After the rod is inserted into the upper cap, the umbrella is assembled onto the rod. Firstly, the rod can be limited by the umbrella to prevent the rod from moving downward; secondly, the rod hole can be shielded by the umbrella to prevent rainwater, dust, etc. from entering the upper cap through the rod hole and causing pollution.

[0017] Reference Figure 1 The present invention provides a waterproof and dustproof insulator iron cap, comprising: a lower cap 1, an upper cap 2, a rod portion 3 and an umbrella portion 4.
[0018] Reference Figure 2 , Figure 3 The lower cap 1 is an inverted barrel-shaped structure. The upper cap 2 is installed on the lower cap 1. The upper cap 2 has a cavity inside and a rod hole 21 on its top. The upper cap 2 has a notch 22 connecting its inner cavity and the rod hole 21. The junction between the notch 22 and the surrounding wall of the upper cap 2 is a trumpet shape that is narrow at the top and wide at the bottom. Figure 4 , the rod 3 is a trumpet shape that is narrow at the top and wide at the bottom, and matches the notch 22. In this way, the rod 3 can be inserted into the upper cap 2 through the notch 22, and the top of the rod 3 extends out of the rod hole 21; then, the rod 3 is moved up in the upper cap 2 to prevent the rod 3 from falling out of the notch 22. Similarly, setting the diameter of the bottom end of the rod 3 to be larger than the diameter of the rod hole 21 can prevent the rod 3 from falling out of the rod hole 21.
[0019] In this embodiment, a limit plate 5 is installed in the upper cap 2, and the limit plate 5 is installed on the lower cap 1 through a spring 6. When the spring 6 is in a normal state, the limit plate 5 rises and supports the rod 3 to move the rod 3 upward; the limit plate 5 is pressed down, and the rod 3 can be disassembled and assembled through the notch 22. In this embodiment, the bottom end of the rod 3 is an elliptical surface, and the limit plate 5 is provided with a groove matching the bottom end of the rod 3.
[0020] In this embodiment, the rod 3 is provided with an external thread 31, and the distance between the external thread 31 and the bottom of the rod 3 is less than the depth of the inner cavity of the upper cap 2. A through hole is provided in the middle of the umbrella 4, and an internal thread matching the external thread is provided in the through hole, and the diameter of the umbrella 4 is greater than the diameter of the rod hole 21. In this way, the umbrella 4 and the rod 3 can be connected by threads. After the rod 3 is inserted into the upper cap 2, the umbrella 4 is assembled on the rod 3. On the one hand, the rod 3 can be limited by the umbrella 4 to prevent the rod 3 from moving downward; on the other hand, the rod hole can be shielded by the umbrella 4 to prevent rain, dust, etc. from entering the upper cap 2 through the rod hole 21 to cause pollution. Specifically, the umbrella 4 covers the upper cap 2 to protect the notch 22. In this embodiment, the spring 6 and the limit plate 5 are both made of conductive metal.
[0021] In this embodiment, the upper cap 2 is a rounded structure to avoid the damage of sharp corners. Similarly, the lower cap 1 is a rounded structure.
[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
