Description
Technical field
The present invention relates to corrosion-resistant fastener fields, lose device more particularly to a kind of bolt anti-corrosion.
Background technology
Bolted anticorrosion, key are exactly to prevent threaded portion dead by corrosion or rust, ensure the switching performance of bolt,
Easy to disassemble and maintenance.Field is lost in bolt anti-corrosion at present, the method generally used is：Bolt material using stainless steel material come
It prevents from corroding.The stainless steel material cost of obvious this method is higher, and mechanical processing difficulty is larger；And for different corruption
Medium is lost, the stainless steel material of the different trades mark need to be used；The mechanical strength of common stainless steel material is relatively low, in same load bar
Under part, the structure size of connection bolt need to be increased.
Invention content
The invention mainly solves the technical problem of providing a kind of bolt anti-corrosions to lose device, solves bolt on fastening apparatus
The problem of head is easily corroded.
In order to solve the above technical problems, one aspect of the present invention is to provide a kind of bolt anti-corrosion erosion device,
Including protective cap, bolt and sealing ring；The bolt includes upper and lower two abutting ends；Limiting is set between two abutting ends
Portion；Screw thread is both provided on upper and lower two abutting ends；The lower abutting end of bolt is installed in connected piece and pedestal, bolt
Upper abutting end is installed in protective cap；The screw hole of the upper abutting end for fitted bolt is additionally provided in the protective cap；The guarantor
The open end of helmet is contacted with connected piece surface, and sealing ring is equipped between the open end and connected piece surface.
Preferably, the open end of the protective cap is equipped with close inside protective cap for corrosive medium to be prevented to enter
Sealing assembly.
Preferably, the limiting section is equipped with the clamping part convenient for clamping and generating the torque arm of force.
Preferably, the sharp processing of the protective cap for regular hexahedron shape or opens up spanner slot.
The beneficial effects of the invention are as follows：A kind of bolt anti-corrosion erosion device is provided, is had the advantages that：
1st, bolt cover is got up using protective cap, has been effectively isolated air or water so that bolt will not touch corrosive medium, prolong
It grown the service life of bolt, reduced maintenance cost.
2nd, for protection cap material using corrosion resistant engineering plastics or common stainless steel, cost is relatively low, is conveniently replaceable, and is protecting
Sealing ring is provided between cap and joint face, corrosive medium can be effectively isolated.
3rd, by using patented technology of the present invention, under the operating mode there are corrosive medium, connection bolt need not use stainless
The ordinary carbon steel that mechanical performance is more preferable, cost is lower may be used in Steel material, can reduce the structure size of connection bolt.
4th, the configuration of the present invention is simple, easy for installation, protective cap can be effectively isolated corrosive medium.
Description of the drawings
Fig. 1 is a kind of sectional view of bolt anti-corrosion erosion device of the present invention；
Fig. 2 is that the structure of protective cap corresponds to sectional view；
Fig. 3 is the front view of bolt；
The label of each component is as follows in attached drawing：1st, protective cap；2nd, bolt；3rd, sealing ring；4th, connected piece；5th, pedestal.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Attached drawing 1 to 3 is please referred to, the embodiment of the present invention includes：
A kind of bolt anti-corrosion loses device, including protective cap 1, bolt 2 and sealing ring 3.Bolt includes upper and lower two abutting ends,
Limiting section is set between two abutting ends.Limiting section is equipped with to clamp and generate the torque arm of force：Such as clamping part is processed as
The bolt head in positive six face, tightens bolt when being used to install.Screw thread is both provided on upper and lower two abutting ends, the lower of bolt 2 is matched
It closes end to be installed in connected piece 4, the upper abutting end of bolt 2 is installed in protective cap 1.It is additionally provided with to coordinate in protective cap 1
The screw hole of the upper abutting end of bolt 2, the open end of protective cap 1 are contacted with 4 surface of connected piece, and the open end is with being connected
Sealing ring 3 is equipped between 4 surface of fitting.The open end of protective cap is equipped with that corrosive medium is prevented to enter inside protective cap
Seal assembly：Such as the open end of protective cap 1 is equipped with the seal groove of installation sealing ring 3.The outside of protective cap 1 opens up six
Angle head or spanner slot, are easily installed and tighten.Bolt 2, which is connected through a screw thread, is fixed on connected piece 4 on pedestal 5, in protective cap 1
The threaded connection of the screw hole in portion and abutting end on bolt 2.
In the present embodiment, during installation, sealing ring 3 is installed in seal groove, by tightening protective cap 1, makes opening for protective cap 1
Sealing sealing ring 3 in mouth end face crush seal slot, can play the role of sealing.Protective cap 1 plays sealing and anticorrosion is made
With almost not stressing, therefore the requirement of mechanical strength of protective cap 1 is relatively low, the material of protective cap 1 can select corrosion resistant engineering
Plastics or common stainless steel.Since protective cap 1 plays sealing function, so the anticorrosion requirement of bolt 2 reduces, therefore bolt 2 can
To be made of carbon steel material, processing cost and material cost can substantially reduce.Protective cap 1 is in repair demolition and replacement
Very convenient, manufacture craft is simple, cost is relatively low and antiseptic property is very good.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright description is made directly or indirectly is used in other relevant technology necks
Domain is included within the scope of the present invention.
