The utility model provides a lightning rod structure with multiple fixed knot constructs, include the ground connection stand and locate the lightning rod on the ground connection stand, the lightningrod includes lightning -arrest needle body and locates the needle point on lightning -arrest needle body top, lightning -arrest needle body's lower extreme is equipped with the flange, the upper endof ground connection stand be equipped with with last flange complex lower flange, the bottom of going up the flange is equipped with socket columns, the upper end of ground connection stand is equipped with cup joints the hole, be equipped with on the lower flange and supply socket columns to insert to cup joint downthehole through -hole, socket columns is D with the grafting degree of depth of cup jointing the hole, 30cm <= D <= 120cm, it fixes so that the ground connection stand links into an integrated entity with lightning -arrest needle body through bolted connection with the lower flange to go up the flange. Once fixed through between last flange and the lower flange like this, rethread socket columns with cup joint the secondary fixation between the hole, form multiple fixed knot structure for fixing between lightning rod and the ground connection stand is firm more, reliable, thereby the better condition that the lightning rod collapses that prevents takes place, promotes thedurability of lightning rod.
