Furthermore, the end parts of the groove and the bolt are both hexagonal, so that the bolt can be prevented from rotating relative to the groove, and the bolt is prevented from loosening.
Further, the fixed surface of bolt scribbles first anticorrosive coating, and thickness is 1mm, and first anticorrosive coating is made for polyurethane material, can avoid the bolt to be corroded in the use, improves the result of use.
Furthermore, the outer surface of the first anticorrosive coating is coated with a wear-resistant layer, the thickness of the wear-resistant layer is 1mm, the wear-resistant layer is made of wear-resistant and corrosion-resistant polymer materials, and the first anticorrosive coating can be prevented from being worn in the bolt connection process.
Furthermore, the outer surface of the nut is coated with a second anticorrosive coating with the thickness of 1mm, and the second anticorrosive coating is a chromium-plated coating, so that the nut can be protected from being corroded.
Compared with the prior art, the utility model has the advantages of:
(1) this scheme is spacing through the recess to the bolt, and the elasticity of rethread elastic gasket is fixed the nut in the side of bolt, can avoid nut and bolt pine to take off, improves the linkage effect, can avoid bolt and nut to be corroded in the use through first anticorrosive coating and second anticorrosive coating, and the rethread wearing layer can protect first anticorrosive coating, improves the result of use.
(2) The end parts of the grooves and the bolts are hexagonal, so that the bolts can be prevented from rotating relative to the grooves, and the bolts are prevented from loosening.
(3) The fixed surface of bolt scribbles first anticorrosive coating, and thickness is 1mm, and first anticorrosive coating is made for polyurethane material, can avoid the bolt by the corrosion in the use, improves the result of use.
(4) The outer surface of the first anticorrosive coating is coated with a wear-resistant layer, the thickness of the wear-resistant layer is 1mm, the wear-resistant layer is made of wear-resistant and corrosion-resistant polymer materials, and the first anticorrosive coating can be prevented from being worn in the bolt connection process.
(5) The outer surface of the nut is coated with a second anticorrosive coating with the thickness of 1mm, and the second anticorrosive coating is a chromium-plated coating, so that the nut can be protected from being corroded.
