Background technology
Bolt：Machine components, the cylindrical threaded fastener of adapted nut.External screw thread (is carried by head and screw rod
Cylinder) a kind of fastener dimerous, need to coordinate with nut, for be fastenedly connected two carry through hole parts.
This type of attachment claims bolt connection.It as nut is screwed off from bolt, can separate the two parts again, therefore bolt connection
It is to belong to be detachably connected.
Easily corroded when existing bolt uses by extraneous water or corrosive corporation, and then it is stuck easily to occur getting rusty,
It can not reuse, the problem of service life is short, be this it is proposed that a kind of anticorrosion type bolt.
Utility model content
The purpose of this utility model is to provide a kind of anticorrosion type bolt, existing to solve to propose in above-mentioned background technology
Bolt easily corroded by extraneous water or corrosive corporation when using, and then it is stuck easily to occur getting rusty, and can not reuse,
The problem of service life is short.
To achieve the above object, the utility model provides following technical scheme：A kind of anticorrosion type bolt, including screw and
Fixing nut is sealed, the upper end of the screw is provided with screw prism, is provided with the screw close to one end of screw prism
Sealing protection is raised, and the sealing fixing nut is arranged on one end away from screw prism on screw, the sealing fixing nut
The upper side away from screw prism is provided with nut-protecting sleeve, and the side away from sealing fixing nut is set on the nut-protecting sleeve
It is equipped with screw protective sleeve.
Preferably, the nut-protecting sleeve is hollow six prism.
Preferably, the nut-protecting sleeve and screw protective sleeve are integral type structure.
Preferably, the sealing protection projection is circular platform type structure.
Preferably, the sealing protection projection is provided with two altogether, and two sealing protection projections are separately mounted to screw
Close to the side of stationary plane on prism and sealing fixing nut.
Preferably, the screw protective sleeve is hollow cylinder shape structure.
Preferably, the screw prism and sealing fixing nut are six prisms.
Preferably, the raised upper side close to mounting surface of the sealing protection is provided with setting-up piece.
Compared with prior art, the beneficial effects of the utility model are：
(1) by designing close to the sealing protection projection of mounting surface side on screw and nut, and then it is easy to bolt to exist
Mounting hole is sealed during use, avoid occur water or corrosive corporation to installation pitting corrosion cause bolt to get rusty can not be just
The problem of often using, and then it is easy to extend the service life of bolt；
(2) it is easy to be socketed in the lower end of nut and screw by designing the nut protective jacket held under the nut, and then is easy to
Bolt is protected, solves the problems, such as that corrosive corporation corrodes from lower end to bolt, is easy to bolt to carry out normal use.
