SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem among the prior art, and the nut structure that proposes for the nut can only carry out one-way rotation, makes the nut can only lock and can not dismantle, and then makes the nut have the theftproof effect.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a nut structure, includes nut body and gasket, the nut body includes interior seat and outer seat, outer seat and gasket fixed connection, outer seat cover is established on interior seat, rotate between interior seat and the outer seat and be connected, the draw-in groove has been seted up on the outer seat, one side of draw-in groove is the flush end face, the opposite side of draw-in groove is the inclined plane, and the rotation direction when its draw-in groove is the direction of flush end face one side and nut body locking is unanimous, the draw-in groove sets up on one side of outer seat towards interior seat, be provided with the extensible member of pegging graft mutually with the draw-in groove on the interior seat.

Through adopting above-mentioned technical scheme, under the initial condition, the extensible member can stretch into in the draw-in groove and keep the butt with the draw-in groove, make the outer seat can not break away from the inner race, when needing to rotate the outer seat, the extensible member can be with the flush end looks butt of draw-in groove, make inner race and outer seat rotate together, make the nut locked, when the outer seat of antiport, the length of extensible member can reduce along the inclined plane of draw-in groove, make the extensible member can not influence the rotation of outer seat, make the inner race can not rotate along with the outer seat is together like this, make the nut can only carry out the locking rotation and can not dismantle the rotation, thereby realize the theftproof of nut.

The utility model discloses further set up to: the extensible member includes the sliding column of spring, the sliding tray has been seted up to the lateral wall of inner seat and the position that corresponds the draw-in groove, sliding column and sliding tray sliding connection, the spring is located between sliding column and the sliding tray bottom, the both ends that the spring kept away from mutually are connected with sliding column and sliding tray respectively.

Through adopting above-mentioned technical scheme, the slip post can stretch into to the draw-in groove because the elasticity of spring for outer seat is established all the time and is established on interior seat, and when outer seat rotated, the length that the slip post stretches out the sliding tray outside can change because of with the change of sliding tray butt position.

The utility model discloses further set up to: one end of the sliding column, which is far away from the spring, is of a hemispherical structure.

Through adopting above-mentioned technical scheme, the one end that the slip post is hemispherical can reduce when carrying out relative rotation between interior seat and the outer seat, and the wearing and tearing that the friction of slip post and sliding tray received to increase the life-span of slip post.

The utility model discloses further set up to: the clamping groove and the telescopic piece are annularly provided with a plurality of clamping grooves and telescopic pieces by taking the inner seat as a circle center.

Through adopting above-mentioned technical scheme, increase the lifting surface between interior seat and the outer seat, the extensible member leads to damaging and warping because the atress is too big when avoiding lock nut to ensure that the nut can be normal install and dismantle.

The utility model discloses further set up to: the inner seat is provided with a first slot at one end deviating from the gasket, the outer seat is provided with a second slot at one end deviating from the gasket and corresponding to the first slot, and the length directions of the first slot and the second slot are consistent.

By adopting the technical scheme, when the nut needs to be disassembled, the outer seat is rotated, so that the first slot and the second slot are corresponding in position, then the professional tool is utilized, the professional tool is inserted into the first slot and the second slot when the outer seat is sleeved with the professional tool, then the professional tool is rotated, the inner seat and the outer seat can be rotated simultaneously, and then the nut can be rotated and disassembled.

To sum up, the utility model discloses following beneficial effect has: when the nut needs to be installed, the outer seat is rotated towards the nut locking rotating direction, the sliding column can be abutted to the flat end face of the clamping groove, the inner seat and the outer seat can rotate together until the nut is locked, when the nut is not loosened by using a professional tool, the outer seat cannot drive the inner seat to rotate together, the nut can only rotate in a single direction, the nut can only be locked and cannot be detached, and then the nut has an anti-theft effect.
