Abstract
The utility model discloses an anticorrosive easily-detached 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; 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 a shallow groove parallel to the axis of the screw rod is formed in the thread section. The anticorrosive easily-detached bolt disclosed by the utility model is simple in structure and is convenient to mount and use; the corrosion influence on the bolt due to the contact of corrosive gas or liquid with the bolt is effectively prevented, the anticorrosive performance of the bolt is improved and the service life of the bolt is prolonged; and during detaching, lubricating oil can be added from the shallow groove, and thus the detaching operation is effectively facilitated.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the quick detachable 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, there is potential safety hazard, and after long-time the use, bolt is fixed together with nut because getting rusty easily, and dismounting is convenient inadequately.
The model utility content
The purpose of this utility model provides a kind of corrosion protection bolt, 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 then influence the use safety of equipment, there is potential safety hazard, and after long-time the use, bolt is fixed together with nut because getting rusty easily, dismantles inadequately problem easily.
For achieving the above object, the technical solution adopted in the utility model is:
The quick detachable 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, and described protective hat cooperates with dovetail groove by fixture block and is installed on the bolt head, and described screw rod upper end is the polished rod section, the lower end is thread section, and described thread section is provided with the shallow slot parallel with screw axis.
The quick detachable bolt of described a kind of corrosion protection is characterized in that: described protective hat adopts corrosion resistant plastics to make.
The quick detachable bolt of described a kind of corrosion protection is characterized in that: described bolt head is cylindrical no bevel bolt head.
The quick detachable bolt of described a kind of corrosion protection, it is characterized in that: described shallow slot is at least one, and the shallow slot degree of depth is 1-3mm.
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 rib is set at the protective hat edge, prevented corrosive gas or liquid from contacting with bolt effectively and bolt has been caused corrosion influence, promote the antiseptic property of bolt, prolonged working life, guaranteed the safe operation of equipment; Employing arranges the design of shallow slot in the screw flight section, when not quick detachable because get rusty when bolt, can add lubricant oil from shallow slot, thereby make things convenient for disassembling section effectively.
