Abstract
The utility model discloses an anticorrosive durable bolt which comprises a bolt head, a screw rod and a protection cap, wherein a dovetail groove is formed in the upper end surface of the bolt head; a trapezoidal clamping block matched with the dovetail groove is formed in the top of the protection cap; a flange extending outwards is arranged on the edge of the protection cap; the protection cap is arranged on the bolt head by matching the clamping block with the dovetail groove; an arc connecting part is arranged at the connected part of the upper end of the screw rod and the bolt head; a polished rod section is arranged at the upper end of the screw rod; a thread section is arranged at the lower end of the screw rod; and an insulating layer made of a soft material is wound on the outer surface of the polished rod section. The anticorrosive durable bolt disclosed by the utility model is simple in structure; the corrosion influence on the bolt due to the contact of corrosive gas or liquid with the bolt is effectively prevented and the safe operation of the equipment is ensured; and in addition, a stress concentrated point is eliminated, and thus the mechanical strength of the bolt is effectively improved and the service life of the bolt is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the durable bolt of a kind of corrosion protection.
Background technique
Bolt is one of modal fastening piece, and it is made up of head and screw rod.It is cylindric that screw rod is, on have outside thread and can use with nut collocation.Screw bolt and nut uses jointly, can connect and fix two parts that have through hole.Existing bolt is applied in when having corrosive operational site, it is more serious that it is influenced by corrosion, make bolt failure, can't reach fastening effect, and then influence the use safety of equipment, and the joint of the bolt head of conventional bolt and screw rod is the right angle, stress is comparatively concentrated when stressed, crack because of fatigue easily and then rupture, so intensity is not good, the life-span is short.
The model utility content
The purpose of this utility model provides the durable bolt of a kind of corrosion protection, be applied in when having corrosive operational site to solve in the prior art traditional bolt, it is more serious that it is influenced by corrosion, make to reach fastening effect by bolt failure, and the joint of the bolt head of conventional bolt and screw rod is the right angle, stress is comparatively concentrated when stressed, crack because of fatigue easily and then rupture, intensity is not good, the problem that the life-span is short.
For achieving the above object, the technical solution adopted in the utility model is:
The durable bolt of a kind of corrosion protection, it is characterized in that: include bolt head, screw rod and protective hat, described bolt head upper-end surface is provided with dovetail groove, described protective hat inner top is provided with the trapezoidal fixture block that matches with dovetail groove, described protective hat edge is provided with the rib of outside extension, described protective hat cooperates with dovetail groove by fixture block and is installed on the bolt head, described screw rod upper end is provided with the arc joint with the joint of bolt head, described screw rod upper end is the polished rod section, the lower end is thread section, is wound with the isolation layer that soft material constitutes on the described polished rod section outer surface.
The durable bolt of described a kind of corrosion protection is characterized in that: described protective hat adopts corrosion resistant plastics to make.
The durable bolt of described a kind of corrosion protection is characterized in that: described bolt head is cylindrical no bevel bolt head.
The durable bolt of described a kind of corrosion protection is characterized in that: described isolation layer is the soft adhesive tape of insulation.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to install, employing arranges protective hat at bolt head, and the design of twining the isolation layer of soft material formation at screw rod polished rod section outer surface, prevent corrosive gas or liquid from contacting with bolt effectively and bolt has been caused corrosion influence, guaranteed the safe operation of equipment; Employing arranges the design of arc joint in screw rod upper end and the joint of bolt head, eliminated stress concentration point, has effectively promoted the mechanical strength of bolt, has prolonged working life.
