Abstract
The utility model discloses a sealing, anti-corrosion and easily-detached bolt comprising a bolt head, a screw rod and a protective cap, wherein a dovetail-shaped slot is arranged in the upper end surface of the bolt head, an annular slot surrounding the screw rod is arranged in the lower end surface of the bolt head, a sealing rubber ring is embedded in the annular slot, a trapezoid clamping block matched with the dovetail-shaped slot is arranged on the inner top of the protective cap, an externally extending stop edge is arranged at the edge of the protective cap, the protective cap is arranged on the bolt head by matching the clamping block with the dovetail-shaped slot, the upper end of the screw rod is a polished rod section, the lower end of the screw rod is a threaded section, and a shallow slot in parallel with the axial line of the screw rod is arranged on the threaded section. The sealing, anti-corrosion and easily-detached bolt disclosed by the utility model has the advantages that the structure is simple, the installation and the use are convenient, the corrosion influence to the bolt caused by the contact of corrosive gas or liquid with the bolt is effectively prevented, the anticorrosion performance of the bolt is improved, the service life is prolonged, and when the bolt is not easily detached due to corrosion, lubricating oil can be added through the shallow slot, so that the detachment operation is facilitated effectively.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the quick detachable bolt of a kind of sealing corrosion.
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 does not mostly possess sealability, be applied in when having corrosive operational site, 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, and dismounting is convenient inadequately.
The model utility content
The purpose of this utility model provides the quick detachable bolt of a kind of sealing corrosion, traditional bolt does not mostly possess sealability in the prior art to solve, be applied in when having corrosive operational site, it is more serious that it is influenced by corrosion, make can't reach fastening effect by bolt failure, 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 sealing corrosion, it is characterized in that: include bolt head, screw rod and protective hat, described bolt head upper-end surface is provided with dovetail groove, the lower end surface is provided with the annular groove around screw rod, be embedded with sealing rubber ring in the described annular 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 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 sealing corrosion is characterized in that: described protective hat adopts corrosion resistant plastics to make.
The quick detachable bolt of described a kind of sealing corrosion is characterized in that: described bolt head is cylindrical no bevel bolt head.
The quick detachable bolt of described a kind of sealing corrosion, 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 sealing rubber ring is set in the bolt head lower end surface, 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.
