the utility model provides a toper evagination antitheft nut, includes the nut body, spanner pole and screw bolt, the nut body is the pipe form, and is provided with the screw thread of being connected with screw bolt cooperation on the inner wall, the nut body outside evenly is provided with a plurality of outside archs, spanner pole both ends all are provided with the joint ring, joint ring inside be provided with nut body complex trepanning, be provided with in the trepanning with the joint that outside arch corresponds is protruding.

Furthermore, the external protrusion and the clamping protrusion are triangular protrusions.

Further, the clearance between the trepan boring and the nut body is equal to or slightly larger than the height of the clamping bulge or the external bulge.

Furthermore, an auxiliary edge is arranged at the top of the nut body.

Further, the external protrusion is located at the top of the nut body, and the external protrusion is located below the auxiliary edge.

Furthermore, the external protrusion and the clamping protrusion are three and correspond to each other.

Further, the external protrusion may also be disposed outside a head of the screw top, and the head of the screw is cylindrical.

By adopting the technical scheme, the beneficial effects of the utility model are that: this toper evagination antitheft nut integrated into one piece, the manufacturing of being convenient for need cooperate dedicated spanner just can dismantle, has the effect of theftproof, and simultaneously through set up the triangle-shaped arch in the circle tubular structure outside, reduce atress contact surface, increase simultaneously with dedicated spanner's atress contact surface, facilitate the use, it is effectual to prevent burglary.

fig. 2 is a schematic view of the nut body mounting structure of the present invention;

fig. 3 is a schematic structural view of the special spanner of the present invention.

The reference numerals are explained below:

1. a nut body; 101. an outer protrusion; 102. an auxiliary edge; 2. screws/bolts; 3. a spanner bar; 4. A snap ring; 401. trepanning; 402. and clamping the protrusion.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, a tapered convex anti-theft nut comprises a nut body 1, a wrench rod 3 and a screw/bolt 2 which are integrally formed, wherein the nut body 1 is in a circular tube shape, the inner wall of the nut body is provided with a thread which is matched and connected with the screw/bolt 2, a plurality of external protrusions 101 are uniformly arranged on the outer side of the nut body 1, clamping rings 4 are arranged at two ends of the wrench rod 3, a sleeve hole 401 which is matched with the nut body 1 is arranged inside each clamping ring 4, and clamping protrusions 402 which correspond to the external protrusions 101 are arranged in the sleeve hole 401.

In this embodiment, outside protruding 101 is triangle-shaped protruding with the protruding 402 of joint, through with nut body 1 suit in trepanning 401, contacts through protruding 402 of joint and outside protruding 101, forms the stress surface, can drive nut body 1 rotatory at the rotatory in-process of spanner pole 3, and then cooperation screw/bolt 2 realizes the fastening, during the dismantlement, reverse rotation spanner body can.

In this embodiment, the gap between the trepan boring 401 and the nut body 1 is equal to or slightly larger than the height of the clamping protrusion 402 or the external protrusion 101, so that the clamping protrusion 402 can be fully contacted with the external protrusion 101, and the slipping is avoided.

In this embodiment, the top of the nut body 1 is provided with an auxiliary edge 102, so that the installation position of the snap ring 4 can be limited by the auxiliary edge 102, and the slipping is avoided.

In this embodiment, the external protrusion 101 is located at the top of the nut body 1, and the external protrusion 101 is located below the auxiliary edge 102, so as to reduce the connection length between the clamping protrusion 402 and the external protrusion 101, and further, when the nut body is fastened or disassembled, the clamping protrusion 402 is separated from the external protrusion 101 by slightly moving downward, after the wrench rod 3 is rotated, the other clamping protrusion 402 in the sleeve hole 401 corresponds to the external protrusion 101, the clamping ring 4 is moved back to the original position through the wrench rod 3, that is, the nut body 1 can be driven to rotate by rotating the wrench rod 3 again, thereby fastening or disassembling is achieved.

In this embodiment, three external protrusions 101 and three clamping protrusions 402 are provided and correspond to each other.

In this embodiment, the external protrusion 101 may also be arranged on the outside of the head of the screw, which is cylindrical, so that the screw may have anti-theft properties.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
