Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

The utility model provides a pair of rust-resistant and easy structure of special-shaped nut of dismouting is as shown in figure 1 and figure 3, including nut main part 1, the surface of nut main part 1 is provided with rust-resistant structure 2, and rust-resistant structure 2 comprises gluing mucigel 21, anti-rust paint layer 22 and high airtight layer 23, and there is the gluing on the surface of nut main part 1 to glue mucigel 21, and the surface covering who glues mucigel 21 has anti-rust paint layer 22 to anti-rust paint layer 22's surface is paintd high airtight layer 23.

When implementing, mutually support through gluing viscose layer 21 and anti-rust paint layer 22 and carry out rust-resistantly, the high airtight layer 23 of rethread is sealed and is carried out the air completely cut off to realize the rust-resistant function of special-shaped nut, thereby prolonged the life cycle of special-shaped nut.

Further, as shown in fig. 2 and 4, a locking structure 3 is arranged on one side of the surface of the nut body 1, the locking structure 3 is formed by combining a locking groove 31, a connecting piece 32, a locking steel sheet 33 and a barb 34, the locking groove 31 is formed in the center of the surface of the nut body 1, the locking steel sheet 33 is connected inside the locking groove 31, the locking steel sheet 33 is welded with the inner wall of the locking groove 31 through the connecting piece 32, the surface of the locking steel sheet 33 is welded with equally spaced barbs 34, the cross sections of the barbs 34 are arc-shaped, and the bottom of the barbs 34 face the same direction as the rotation direction of the nut body 1.

During implementation, the connecting piece 32 is used for welding the anti-loosening steel sheet 33 on the inner wall of the anti-loosening groove 31, and the barb 34 on the surface of the anti-loosening steel sheet 33 is mutually pressed with the mounting surface, so that the phenomenon that the special-shaped nut is prevented from being withdrawn and loosened is achieved, and the screwing force of the special-shaped nut after use is increased.

Further, as shown in fig. 5, a dismounting structure 4 is disposed on the other side of the surface of the nut body 1, and the dismounting structure 4 is composed of a dismounting groove 41, a damage-preventing groove 42 and a damage-preventing insert 43, the dismounting groove 41 is disposed on the surface of the nut body 1, the damage-preventing groove 42 is disposed at the corner position of the inner wall of the dismounting groove 41, the damage-preventing insert 43 is embedded in the damage-preventing groove 42, and the plane of the outer surface of the damage-preventing insert 43 is coplanar with the plane of the inner wall of the corresponding dismounting groove 41.

During implementation, the dismounting groove 41 facilitates the rotation of the nut body 1, and meanwhile, the damage prevention insert 43 in the damage prevention groove 42 prevents the corners of the dismounting groove 41 from being worn when the nut body 1 rotates, so that the convenience in dismounting the special-shaped nut is improved.

The working principle is as follows: during the use, at first rust-resistant through rust-resistant structure 2 to nut main part 1, when rust-resistant structure 2 implemented, mutually supported through gluing viscose layer 21 and anti-rust paint layer 22 and carried out rust-resistant, the high airtight layer 23 of rethread seals and completely cuts off the air to realize the rust-resistant function of special-shaped nut, thereby prolonged the life cycle of special-shaped nut.

Prevent the pine phenomenon of nut main part 1 through anti loosening structure 3 afterwards, when anti loosening structure 3 implemented, welded locking steel sheet 33 at the inner wall of anti loosening groove 31 through connection piece 32, sticis each other with the installation face through barb 34 on locking steel sheet 33 surface to realize that special-shaped nut prevents moving back the pine phenomenon of taking off, thereby increased the spiral shell power after special-shaped nut used.

Later make things convenient for the dismouting of nut main part 1 through dismouting structure 4, when dismouting structure 4 was implemented, make things convenient for the rotation of nut main part 1 through dismouting groove 41, the corner of dismouting groove 41 takes place wearing and tearing when preventing that nut main part 1 from rotating through the inside loss prevention mold insert 43 of loss prevention groove 42 when rotatory simultaneously to convenience when having improved the dismouting of special-shaped nut, the use work of final completion special-shaped nut.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
