[0019] As Figures 1 to 4 shown, the line-type lightning arrester of the present utility model mainly includes a lightning arrester body 1 and a disconnector body 4. The two are the main structures for lightning protection functions, and their internal structures and working principles are all prior arts. The top of the disconnector body is fixedly connected to the lightning arrester body. A clamping mechanism and a fixing mechanism are provided on the disconnector body, and the clamping structure is arranged on the right side of the fixing structure. Among them,

[0020] The clamping mechanism includes a mounting bracket 2, an insulating bracket group 3, and two clamping pieces 10; a through hole is provided on the left side of the insulating bracket group. The mounting bracket is arranged in the through hole and fixedly connected to the insulating bracket group; two arc-shaped connecting pieces 15 are fixedly connected to the upper and lower ends on the right side of the mounting bracket. A round hole is provided at the top of each arc-shaped connecting piece. A rotating shaft 7 is detachably arranged between the two arc-shaped connecting pieces through the round holes, and both ends of the rotating shaft are respectively arranged in the two round holes; four metal rings 8 are sleeved along the axial direction on the rotating shaft, and two connection parts 9 are fixedly connected to the four metal rings. The four metal rings are distributed up and down, and the two connection parts are distributed front and back. The front connection part is fixedly connected to the upper two metal rings, and the rear connection part is fixedly connected to the lower two metal rings. The right sides of the two connection parts are respectively fixedly connected to the two clamping pieces. Two connection holes are provided on the right side of the front ends of the two clamping pieces, and a rubber layer 11 is arranged on the clamping side of the clamping piece; the disconnector body is clamped and fixed between the two rubber layers by the two clamping pieces.

[0021] Place the disconnector body between the two rubber layers. The rubber layer can increase the friction force, avoid abrasion of the disconnector body during the clamping process, and improve the insulation ability of the installation part; rotate the clamping piece towards the disconnector body, and the rubber layer clamps the outer surface of the disconnector body along with the clamping piece. During the rotation process, the connection part rotates the clamping piece, and the connection part drives the metal ring to rotate on the surface of the rotating shaft. The rotating shaft is in a fixed state between the two arc-shaped connecting pieces. Pass the bolt through the connection holes of the two clamping pieces and tighten it, and then pass the bolt through the hole positions on the two connection parts and tighten it to realize the clamping and fixing of the disconnector body. Thus, the problem that it is not convenient to disassemble and assemble between the lightning arrester and the mounting bracket is solved.

[0022] The fixing mechanism includes a bottom plate 5, a top plate 6, a positioning member 14, two clamping plates 13 and four limiting blocks 12; the top plate and the bottom plate are respectively detachably connected to the opposite surfaces of the two arc-shaped connecting members; the top plate is arranged on the right side of the positioning member, and the positioning member is fixedly connected to the top right of the mounting bracket; a first chute is formed at the bottom right of the top plate, the four limiting blocks are distributed up and down, the two upper limiting blocks are both arranged in the first chute, the two clamping plates are respectively fixedly connected to the bottoms of the two upper limiting blocks, and the two lower limiting blocks are respectively fixedly connected to the bottoms of the two clamping plates; a second chute is arranged at the top right of the bottom plate, the two lower limiting blocks are both arranged in the second chute, and the two clamping plates can slide between the bottom plate and the top plate. The bottom plate and the top plate are both arranged in the same longitudinal horizontal plane, and the first chute and the second chute are both arranged in the same longitudinal horizontal plane.

[0023] The notch on the right side of the top plate is snapped into the right side of the positioning member for positioning; the bolt is passed through the upper arc-shaped connecting member and the top plate and tightened to install the top plate; the four limiting blocks are respectively passed through the first chute and the second chute and the clamping plates are slid towards each other so that the clamping plates tightly clamp the two connecting parts; after the two clamping plates and the two connecting parts are in a front-back combined state, the bolts are sequentially passed through the clamping plates and the connecting parts and tightened to achieve installation and fixation. Thus, the problem that the position of the lightning arrester may rotate and shift around the rotating shaft after installation is solved.
