Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, a locking anti-theft nut group is used for fastening a workpiece in cooperation with a bolt 3, the nut group comprises a main nut 1 and a secondary nut 2, the main nut 1 comprises an anti-theft sleeve 11 and a nut main body 12 which are integrally and concentrically arranged, the anti-theft sleeve 11 is cylindrical, the nut main body 12 is hexagonal nut-shaped, the secondary nut 2 is triangular prism-shaped, one end of the nut main body 12 is integrally provided with a conical protrusion 121, one end of the secondary nut 2 is provided with a conical groove 21, the conical protrusion 121 is connected with the conical groove 21 in a matched manner, and the secondary nut 2 is arranged in the anti-theft sleeve 11. A main internal threaded hole is formed in the main nut 1, and the main internal threaded hole is sequentially and integrally formed in the anti-theft sleeve 11, the nut main body 12 and the conical protrusion 121; the secondary nut 2 is internally provided with a secondary internal threaded hole, the specifications of the primary internal threaded hole and the secondary internal threaded hole are consistent, the primary internal threaded hole and the secondary internal threaded hole are aligned and matched for use, and the primary internal threaded hole and the secondary internal threaded hole are matched with the specifications of the bolt 3 in matched connection. During operation, the main nut 1 is screwed to the threaded end of the bolt 3 by adopting an air pressure impact wrench, namely, the nut main body 12 is screwed to drive the anti-theft sleeve 11 to be screwed to the bolt 3 or one side of a workpiece on the bolt 3, the workpiece on one side of the bolt 3 is primarily fastened, then the secondary nut 2 is screwed to the bolt 3 by adopting a specific tool (generally a sleeve with a triangular hole and an air pressure impact wrench) and is tightly pressed to one end of the main nut 1, namely, the secondary nut 2 is screwed into the anti-theft sleeve 11 of the main nut 1, so that the conical groove 21 is tightly adhered to the conical protrusion 121; so that the whole nut set can achieve the anti-loose and anti-theft effects.

In practical application, the end face of the anti-theft sleeve 11 is flat and smooth, or the side of the anti-theft sleeve 11 close to a workpiece is flat and smooth, so that a gasket is not required when the nut set is used, and materials are saved; at this time, the anti-theft sleeve 11 can play a role of both anti-theft effect and gasket.

In practical applications, the tapered protrusion 121 may be designed as a tapered solid structure integrated with the nut body 12, and may be also designed as a tapered structure integrated with the nut body 12, surrounded by a plurality of metal sheets (not shown in the figure), where the metal sheets are obliquely fixed at one end of the nut body 12, and the metal sheets have elasticity; thus, when the tapered groove 21 of the secondary nut 2 is screwed and tightly attached to the tapered protrusion 121, the tapered groove 21 can deform the metal sheet inward or toward the bolt 3 to press down to a certain extent, so that the main nut 1 and the bolt 3 are locked more tightly, and the anti-loosening effect can be further achieved.

The implementation of the utility model has the advantages that: during operation, the main nut 1 is screwed onto the bolt 3 by adopting an air pressure impact wrench, the secondary nut 2 is screwed onto the bolt 3, and the secondary nut 2 is screwed into the anti-theft sleeve 11 of the main nut 1, so that the conical groove 21 is attached to the conical protrusion 121 for compaction, namely, the secondary nut 2 is compacted at one end of the main nut 1; the secondary nut 2 is screwed into the anti-theft sleeve 11 of the main nut 1, and the anti-theft sleeve 11 is cylindrical, so that the nut set has an anti-theft effect and can be disassembled only by adopting a specific tool; through setting up two nuts of main nut 1 and secondary nut 2, and secondary nut 2 compresses tightly laminating in the toper protruding 121 one side of main nut 1 through the awl groove 21, so this nut group can play locking effect. The secondary nut 2 is arranged in a triangular prism shape, and a specific wrench tool is required to be used for disassembly, so that the anti-theft effect can be further achieved; through setting up theftproof sleeve 11 terminal surface and leveling smooth, this nut group can need not to use the gasket when using, practices thrift the cost, and it is more convenient to operate. The nut group has simple integral structure and enriches market patterns.
