A salt mist
rust-proof
corrosion-resistant double-end electronic screw comprises a head end and a containing groove, the containing groove is formed in the inner wall of the head end, a
rust-proof mechanism is arranged on the inner wall of the head end, the
rust-proof mechanism comprises a sealing ring, the outer wall of the sealing ring is fixedly connected with the head end, the inner wall of the sealing ring is slidably connected with a round rod, and the outer wall of the sealing ring is fixedly connected with the round rod. The end of the round rod is fixedly connected with a push plate, a round wheel is installed on the inner wall of the round rod, and the end of the push plate is movably connected with
sponge. Salt-mist-resistant anti-rust oil is injected into a containing groove through an injection
pipe, the salt-mist-resistant anti-rust
oil can be absorbed and stored by a
sponge, an adjusting piece is manually rotated to move downwards at the head end, a round rod is pushed to move on a sealing ring in the rotating process of the adjusting piece, the round rod can push a push plate to extrude the
sponge, and then the sponge is sealed. Salt-mist-resistant anti-rust oil is extruded from the sponge, flows into the conveying groove and is conveyed to the surface of the thread section, so that rust prevention and
corrosion prevention of the double-end electronic screw are achieved, and decoration and
mechanical strength are kept.
