Description

Technical Field

[0001] This utility model belongs to the field of electrical insulation technology and relates to a highly reliable electrical insulation structure. Background Technology

[0002] Electrical equipment refers to generators, transformers, power lines, circuit breakers, high and low voltage switchgear, and other equipment in a power system. To ensure safety during use, operators need to use electrically insulated levers to remotely operate switches when switching on or off high-voltage equipment. This ensures operational safety and prevents serious accidents.

[0003] In practical use, when using telescopic electrical insulating pull rods to operate switches inside electrical equipment, a large pulling force is generally required. After adjusting the length of the pull rod, it is difficult to stably fix the extended end to the pull rod body. During the pulling process, the extended end is prone to slippage, leading to the failure of the operation. In addition, the operating heads are fixed, and once damaged, maintenance is expensive. Summary of the Invention

[0004] The purpose of this invention is to provide a highly reliable electrical insulation structure to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A highly reliable electrical insulation structure includes an insulating rod body, a handle, a movable rod, an operating pull head, and a mounting head. The movable rod is movably sleeved inside the insulating rod body. One end of the movable rod is threaded with a mounting head, and one end of the mounting head is fixedly connected to an operating pull head. Displacement sliding plates are provided on both sides of the movable rod. Displacement guide grooves are formed on both sides of the inner wall surface of the insulating rod body. The displacement sliding plates slide inside the displacement guide grooves. One end of the insulating rod body is fixedly connected to a handle.

[0007] In the aforementioned high-reliability electrical insulation structure, a side knob is threadedly connected to both sides of the end of the insulating pull rod body, and a positioning rod is fixedly connected to the bottom of the side knob.

[0008] In the aforementioned high-reliability electrical insulation structure, the displacement slide plate has multiple positioning holes arranged side by side inside, and the positioning rod is inserted into the positioning holes.

[0009] In the aforementioned high-reliability electrical insulation structure, one end of the mounting head is fixedly connected to a threaded head, and one end of the movable rod is provided with a threaded groove, with the threaded head threadedly connected inside the threaded groove.

[0010] In the aforementioned high-reliability electrical insulation structure, locking blocks are provided on both sides of the mounting head, and a screw is fixedly connected to one end of each locking block.

[0011] In the aforementioned high-reliability electrical insulation structure, a limiting sleeve is movably fitted at one end of the movable rod. Two locking grooves are opened on one end face of the limiting sleeve. The locking block is placed inside the locking groove. A through hole is opened on one side of the locking groove. One end of the screw passes through the through hole and is threadedly connected to the locking nut on one side of the limiting sleeve.

[0012] Compared with the prior art, the advantages of this utility model's high-reliability electrical insulation structure are as follows:

[0013] The insulating pull rod of this application has an internal movable rod. When the movable rod slides, it is supported by displacement sliding plates on both sides, which improves stability during sliding. When positioning is required, the side knobs on both sides can be rotated simultaneously to insert two positioning rods into the positioning holes, thereby positioning the movable rod on both sides. This makes the movable rod more stable. A detachable operating pull head is provided on one side of the mounting head. During installation, the mounting head is threaded into the threaded groove through the threaded head. Then, the limiting sleeve at one end of the movable rod is slid, and the limiting sleeve moves towards the screw rod. The screw rod passes through the through hole, and then the nut is locked on one side of the limiting sleeve. At the same time, the locking block enters the locking groove for limiting. This makes the mounting head and operating pull head more stable and prevents easy slippage, making operation more stable. Attached Figure Description
