Description

Technical Field

[0001] The utility model relates to the technical field of porcelain insulators, in particular to a suspension porcelain insulator with a disassembly and assembly structure. Background Art

[0002] Porcelain insulator is an insulating device made of electrical ceramics, used to support and fix busbars and live conductors, and provide sufficient distance and insulation between live conductors or between conductors and the ground. It plays an important role in overhead transmission lines, including supporting conductors and preventing current from returning to the ground. The main function of porcelain insulators is to isolate live conductors from brackets or power equipment through their insulating properties and structural strength, ensuring the safe operation of the power system.

[0003] According to a disclosed suspension porcelain insulator with a quick-change structure for a foot body (publication number: CN114783700A), a cap body is installed on the top of the insulator body in the above application, the bottom of the foot body passes through the insulator body and is installed with a connecting platform, a through hole is provided inside the connecting platform, an insertion rod is installed inside the foot body at the upper end of the insulator body, one side of the insertion rod passes through the cap body and is installed with a nut, and the other side passes through the cap body and is installed with a fixing nut, a connecting groove is provided on the top of the cap body at the upper end of the foot body, a shock-absorbing spring is installed inside the connecting groove, and a clamping block is installed on the other side of the shock-absorbing spring.

[0004] However, after the above-mentioned insulating terminals are used outdoors for a long time, the bolts will rust due to long-term exposure to wind and rain. This will make it difficult to remove the insulator when replacing the insulator body, increasing the complexity and time cost of the maintenance process. At the same time, if the bolts are severely rusted, the insulator body will become loose or unstable, affecting the fixing performance and stability of the insulator. In view of this, we propose a suspension porcelain insulator with a disassembly and assembly structure. Utility Model Content

[0013] Preferably, the magnetic member is magnetically connected to the magnet, and after the insertion rod is inserted, the magnetic member is attracted by the magnet, thereby causing the magnetic member to rotate around the insertion rod.

[0014] Preferably, one end of the spring is fixedly connected to the side wall of the limiting ring, and the other end of the spring away from the limiting ring is fixedly connected to the inner wall of the cap body.

[0015] Preferably, the movable rods are symmetrically arranged in two groups, and the two groups of movable rods are symmetrically arranged on both sides of the insertion rod. The movable rods move toward the insertion rod, thereby pushing the magnetic member to converge toward the insertion rod.

The spring pushes the movable rod to prevent the movable rod from swinging or moving uncontrollably. BRIEF DESCRIPTION OF THE DRAWINGS
