Therefore, to reduce the likelihood of corrosion of the exposed threads of the foundation when exposed to the environment, an effective rust inhibiting means is desired. The traditional simple exposed thread rust prevention mode comprises the steps of brushing rust prevention paint, winding a rust prevention film and the like, has a certain effect on exposed thread rust prevention, is easily damaged by the outside, influences the rust prevention performance of the exposed thread rust prevention, is not suitable for the environment with moisture or water, and can be improved and optimized.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a purpose, be exactly to prior art exist not enough, and provide an expose the technical scheme of the rust-resistant device of bolt, this scheme adopts the cover body will expose the bolt cover in inside, can prevent effectively that the exposure screw thread from exposing the condition emergence corroded in the environment, can avoid simultaneously exposing the screw thread and receive external damage, still be suitable for in the wet environment that has water.
The scheme is realized by the following technical measures:
an antirust device of an exposed bolt comprises a cover body and an inverted convex nut; the cover body is a cavity structure with one open end; one side of the cover body close to the opening end is provided with a step; the inverted convex nut is fixed on the step surface in the cover body; the cover body can cover the exposed bolt; the internal thread of the inverted convex nut is matched with the external thread of the exposed bolt.
The scheme is preferably as follows: a threaded blind hole is formed in the step surface of the cover body; the inverse convex nut is provided with a through hole at a position corresponding to the threaded blind hole; the inverted convex nut is fixed on the step surface in the cover body through a socket head cap screw.
The scheme is preferably as follows: an elastic washer is arranged between the contact surface of the inverted convex nut and the inner hexagon screw.
The scheme is preferably as follows: the opening end of the cover body is provided with a sealing gasket.
The scheme is preferably as follows: the cover body is made of galvanized steel material.
The scheme is preferably as follows: the inverted convex nut is made of non-metal materials.
The scheme is preferably as follows: the inner wall of the cover body is not contacted with the exposed bolt.
The scheme is preferably as follows: the outer end face of the top of the cover body is of a solid hexagonal nut structure.
The beneficial effect of this scheme can learn according to the statement to above-mentioned scheme, because the structure that adopts the cover body, the nut of falling the convex, sealed pad and socket head cap screw in this scheme can cover the bolt that exposes inside the cover body, can play sealed effect that exposes the bolt simultaneously, can avoid exposing the screw thread and receive external damage and receive the condition emergence of external environment corruption to still be suitable for in the wet environment that has water.
Therefore, compared with the prior art, the utility model has the substantive characteristics and the progress, and the beneficial effects of the implementation are also obvious.
