Abstract

The invention provides a bolt protection tool and a bolt connection assembly. The bolt protection tool comprises a body and a suction piece, wherein the body comprises a top wall and a side wall whichis fixed on the top wall, the top wall and the side wall together enclose to form an accommodating cavity with a downward opening, the containing cavity is used for containing a bolt, the suction piece is fixed on the side wall, and the suction piece is used for adsorbing the body on a connecting plate. The invention further provides the bolt connection assembly which comprises the connecting plate, the bolt, a nut and the bolt protection tool, wherein a connecting hole is formed in the connecting plate, one end of the bolt penetrates through the connecting plate to be matched with the nut, the bolt protection tool sleeves the bolt, and the suction piece of the bolt protection tool is attracted to the connecting plate. According to the bolt protection tool and the bolt connection assembly, when the body sleeves the bolt, the suction piece can adsorb the body on the connecting plate, so that the bolt protection tool is prevented from falling off, and the service life of the bolt is prolonged.

Description

technical field [0001] The invention relates to mechanical tool technology, in particular to a bolt protection tool and a bolt connection assembly. Background technique [0002] As a commonly used connection method, bolt connection is widely used in the field of production and processing technology. Bolts are generally used in conjunction with nuts. When in use, a connecting hole can be arranged on the connecting plate, and then one end of the bolt is passed through the connecting hole to cooperate with a nut to realize fixed connection. [0003] In the prior art, in order to prevent the bolts from being corroded and rusted by oxygen or moisture in the air, a layer of butter is generally coated on the surface of the bolts, and then a protective cover is used to isolate the air. The protective sleeve is a cylindrical structure with one end closed and the other open. It can be sleeved on the outside of the bolt, and the inner diameter of the protective sleeve is equal to the...
