Description

Technical Field

[0001] This utility model relates to the field of pin insulator technology, and in particular to a fastening pin insulator. Background Technology

[0002] Insulators are devices used in overhead transmission lines to support and fix conductors, and to isolate the electrical connection between the conductors and the towers and the ground. Pin-type insulators possess excellent bending resistance, impact resistance, seismic resistance, and explosion-proof performance. They offer reliable internal insulation, are lightweight, and are an ideal replacement for traditional tempered glass insulators. For example, the Chinese utility model patent CN209029172U describes a pin-type insulator fixing device that integrates an anti-loosening nut with a horizontal plate. Both are made of the same material and have the same coefficient of thermal expansion, eliminating the risk of loosening or detachment due to hard contact. Furthermore, their integrated design prevents loosening or detachment caused by external force resonance. This integration significantly increases the contact area, resulting in a more secure connection. The inclusion of an anti-loosening nut, a fastening nut, an anti-loosening washer, and a locking nut further reduces the safety hazard of pin-type insulator detachment.

[0003] The above devices still have some problems in use. When fixing the pin insulator, it is only fixed by two nuts on the top and bottom of the horizontal plate. When encountering strong winds outdoors, the fixing effect of the nuts is not enough to block the excessive wind force, causing the insulator to fall off and affecting the safety of power transmission. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a fastening-type pin insulator, characterized by comprising an insulator body, a crossarm, and a fastening structure. The insulator body passes through an opening on the crossarm, and the fastening structure is installed on the outer side of the crossarm. The fastening structure consists of a fastening nut, an anti-loosening nut, side plates, a sliding groove A, a sliding groove B, a top plate, a bottom plate, a limiting block, a through hole, a limiting rod, a limiting nut, a blocking block A, and a blocking block B. A fastening nut is installed on the outer side of the insulator body above the crossarm, and an anti-loosening nut is installed on the outer side of the insulator body below the crossarm. Side plates are installed on both sides, with a sliding groove A above the side plates and a sliding groove B below them. A blocking block A is placed between the side plates and the fastening nut, and a blocking block B is placed between the side plates and the anti-loosening nut. A top plate is installed inside the sliding groove A between the two side plates, and a bottom plate is installed inside the sliding groove B between the two side plates. Limiting blocks are installed on both sides of the side plates, with through holes above and below each limiting block. A limiting rod is placed between the through holes on both sides of the crossarm, and limiting nuts are installed at both ends of the limiting rod.

[0005] The beneficial effects of this utility model are: This utility model discloses a fastening pin-type insulator. The operator inserts the insulator body into the opening on the crossarm, tightens the fastening nut and anti-loosening nut, and installs the side plates on both sides of the crossarm tightly against it. A top plate is installed between the two sliding grooves A on both sides, and a bottom plate is installed between the two sliding grooves B on both sides. A side plate is installed on each side of the crossarm, and two limiting blocks are installed on each side of the side plate. Each limiting block has through holes at its top and bottom, and a limiting rod is inserted into the through holes of the limiting blocks, for a total of four limiting rods. A limiting nut is installed at each end of each limiting rod. Tightening the limiting nuts completes the fastening and limiting of the insulator. This device adds side plates to both sides of the crossarm. The side plates themselves can resist wind blowing on the insulator in windy weather. Simultaneously, the blocking blocks installed between the side plates can press and tighten the fastening nut and anti-loosening nut. Furthermore, tightening the limiting bolts further presses and tightens the side plates on both sides of the crossarm, making the installation of the insulator more stable and secure.
