Description

Technical Field

[0001] The utility model relates to the field of lightning protection devices, in particular to a fixed structure for the down conductor of a lightning protection device. Background Art

[0002] Traditional lightning protection grounding uses metal materials such as iron and copper. Several horizontal and vertical deep trenches are dug on an idle land and buried in the soil as grounding bodies. Generally, the lightning protection devices of buildings are divided into two categories: external lightning protection devices and internal lightning protection devices.

[0003] The disclosed CN220156128U discloses a fixed structure for the down conductor of a lightning protection device, which relates to the field of lightning protection devices. It includes a first fixing plate. A sleeve rod is sleeved on the right side of the first fixing plate. The sleeve rod is threadedly connected with an inner rod. The right end of the inner rod is fixedly connected with a second fixing plate. There are two limiting sleeves on the right side of the second fixing plate, and there are three limiting sleeves in total; the other limiting sleeve is fixedly connected with one end of an adjusting rod. The first guiding rod and the second guiding rod can adjust the distance between the two limiting sleeves to wrap and protect the down conductor body. The combination of a sleeve ring and a limiting bolt is used to limit the down conductor body. The baffle can support the right side of the limiting sleeve to further improve the fixing effect on the down conductor body. The adjusting rod drives the limiting sleeve to rotate on the right side of the first fixing plate, which can adjust the installation direction and position of the down conductor body and increase the contact area between the whole structure and the down conductor body. The installation strip and the first fixing plate can realize the installation and fixation of the left side of the whole structure. However, the prior art still has disadvantages:

[0004] Although the existing down conductor fixing structure can effectively improve the fixing effect on the down conductor body, the sliding connection design between its sleeve rod and inner rod makes it impossible to accurately and stably adjust the distance between the down conductor and the device in actual application.
