Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a lightning arrester which is easy to install. Background Art

[0002] A lightning arrester is a protective device that releases overvoltage energy and limits the amplitude of overvoltage on the insulation of equipment. It is usually connected between the conductor and the ground and in parallel with the protected equipment. The working principle of a lightning arrester is different from that of a lightning rod and a lightning conductor.

[0003] Traditional lightning arresters are usually installed on the top of the tower by screwing screws into the base. However, on rainy days, long-term immersion in rainwater may cause the screws to rust, and they do not have the function of quick disassembly. Therefore, when the lightning arrester has problems and needs to be repaired, it is more difficult. In addition, the installation accessories can only be installed with the same model of fixed poles, and it is difficult to apply to poles of different widths. Therefore, we propose a lightning arrester that is easy to install. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a lightning arrester that is easy to install and has the advantages of being adaptable to different models and easy to fix, thereby solving the problems raised by the above-mentioned background technology.

[0010] As a preferred technical solution of the utility model: a circular groove is provided on the top of the base, and a rectangular plate 1 is fixedly installed on the bottom of the base.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The arrester which is easy to install is adapted to the diameter of the rotating shaft through the inner wall diameter of the arc-shaped groove. When the rotating shaft rotates to the front end of the rectangular plate, the rotating shaft enters the arc-shaped groove. At this time, the hook-shaped plate is forced to be lifted upward, and the hook-shaped plate rotates on the outer wall of the circular shaft. At this time, the rotating shaft enters the inner wall of the hook-shaped plate. The outer wall of one end of the hook-shaped plate is longer, so that when the rotating shaft is clamped into the inner wall of the hook-shaped plate, the rotating shaft can be self-locked through the hook-shaped plate to avoid the bottom plate from falling off due to external force. Through the circular groove, rainwater can be discharged along the circular groove, so that rainwater will not stay on the surface of the base, avoiding long-term corrosion and damage to the base.

[0013] 2. The arrester which is easy to install can drive the connecting rod to rotate the rotating plate by rotating the rotating shaft, so that the rotating plate can drive the arc plate 2 of the outer wall of the two circular rods to expand the angle, so that the two groups of arc plates 2 can push the circular rod 1, so that the circular rod 1 can drive the pair of clamping blocks of the circular ring to move, so that the two groups of clamping blocks can drive the elastic parts to stretch. At this time, the two groups of clamping blocks can clamp the fixed local poles, so that when facing different fixed poles, they can also be clamped, which is more convenient.
