Description

Bolt with corrosion-resistant sealing structure Technical Field The utility model belongs to the technical field of bolts, and particularly relates to a bolt with a corrosion-resistant sealing structure. Background The bolt is a mechanical part, is a cylindrical threaded fastener matched with a nut, is a fastener consisting of a head part and a screw rod, and can realize a corrosion-resistant effect for the bolt after being sprayed with a corrosion-resistant coating on the surface of the bolt, so that the bolt is corrosion-resistant. The following problems exist in the actual use process of the existing bolts with corrosion resistance: 1. When the traditional bolt with corrosion resistance is in actual use, as the bolt is installed inside the screw hole, the gap between the screw hole and the bolt does not have a sealing effect, and external dust or dirt can possibly enter through the gap, so that the bolt is blocked in the subsequent disassembly process, and the bolt is inconvenient to use; 2. Most of the bolts with corrosion resistance are formed by integrating the screw rod and the screw head in the using process, so that the bolts have no detachable effect, and when the bolts are worn in the long-time using process, the whole bolts can only be replaced at the moment, and the cost is high in using. Disclosure of utility model The utility model aims to provide a bolt with a corrosion-resistant sealing structure, so as to solve the technical problem in the background technology. The bolt with the corrosion-resistant sealing structure comprises a bolt head and a screw rod, wherein a first clamping groove is formed in the surface of the bolt head, a clamping plate is clamped in the first clamping groove, an inner thread groove is formed in the surface of the clamping plate, an outer thread ring is sleeved in the inner thread groove, a clamping ring is welded on the inner wall of the outer thread ring, a fixing ring is sleeved in the inner thread groove, a second clamping groove is formed in the surface of the fixing ring, the clamping ring is embedded in the second clamping groove, a sealing ring is bonded on the surface of the fixing ring, and the surface of the sealing ring is attached to the bolt head.
