Abstract
The invention discloses a bolt with an anti-theft device. The bolt comprises a bolt head and a bolt rod arranged at one end of the bolt head. Threads are arranged on the outer side of the bolt rod. The bolt head comprises the anti-theft device and a gasket arranged at the bottom of the anti-theft device. One end of the gasket is connected with the bolt rod. The anti-theft device comprises a single-direction stress groove, a first single-direction stress block arranged on one side of the single-direction stress groove and a second single-direction stress block arranged on the other side of the single-direction groove. The first single-direction stress block and the second single-direction stress block are both oblique faces, and the cross sections are in a semicircular shape. The first single-direction stress block and the second single-direction stress block are the same in shape and size. The bolt is novel is overall design and is simple in designed structure, the bolt has the advantages of being simple in structure and reasonable in design, and a structure which can only be locked in a single direction is arranged on the bolt head so that after the bolt is tightly screwed, the bolt cannot be detached through a common spanner.
Description
Technical field
The present invention relates to bolt technical field, be related specifically to a kind of bolt with anti-theft device.
Background technique
Bolt, nut are one group of common knockdown chain connecting connector, bolt major part comprises bolt head and bolt shank, and bolt head is often outer regular hexagon or interior regular hexagon mechanism, and the bolt of this structure can use various Wrench to screw flexibly, and then this structure also result in some set up and equipment stolen, especially power equipment, not only grievous injury national interests, but also create various potential safety hazard.
But for the deficiencies in the prior art, developer be necessary to develop a kind of structure simple, reasonable in design, arrange on bolt head a kind of can only single direction locking structure, make bolt tightening after not by a kind of bolt with anti-theft device that common wrench disassembles.
Summary of the invention
For solving prior art Problems existing, the object of the invention provide a kind of structure simple, reasonable in design, arrange on bolt head a kind of can only single direction locking structure, make bolt tightening after not by a kind of bolt with anti-theft device that common wrench disassembles.
For solving above technical problem, the present invention comes to be realize by the following technical solutions: a kind of bolt with anti-theft device, comprises bolt head and the bolt shank being arranged on bolt head one end, is provided with screw thread outside described bolt shank;
Described bolt head comprises anti-theft device and is arranged on the packing ring bottom anti-theft device, and described packing ring one end is connected with bolt shank;
Described anti-theft device comprises single load bearing groove, be arranged on the first single load bearing block of single load bearing groove side and be arranged on the second single load bearing block of unidirectional groove opposite side, described first single load bearing block and the second single load bearing block are plane of inclination, and cross section is semicircle, described first single load bearing block is identical with the second single load bearing block size shape.
In a preferred embodiment of the invention, described gasket diameters is greater than bolt shank diameter.
In a preferred embodiment of the invention, described screw thread is right-handed thread.
In a preferred embodiment of the invention, described screw head cross section is circular.
Beneficial effect of the present invention is, compared with prior art, bolt head of the present invention comprises anti-theft device and is arranged on the packing ring bottom anti-theft device, packing ring one end is connected with bolt shank, anti-theft device comprises single load bearing groove, be arranged on the first single load bearing block of single load bearing groove side and be arranged on the second single load bearing block of unidirectional groove opposite side, first single load bearing block and the second single load bearing block are plane of inclination, and cross section is semicircle, first single load bearing block is identical with the second single load bearing block size shape, and then make bolt after rotation is tightened, cannot be turned on by common spanner, thus effectively reduce State Grid's equipment by the incidence rate of stealing, loss is reduced to country, improve the Safety performance of power equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is left view of the present invention.
Fig. 3 is plan view of the present invention.
Numeral and the corresponding part title represented by letter in figure:
1. the first single load bearing block 2. second single load bearing block 3. packing ring 4. bolt shank 5. screw thread 6. single load bearing groove.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to shown in Fig. 1, Fig. 2, Fig. 3, the present invention is a kind of bolt with anti-theft device, comprises bolt head and the bolt shank 4 being arranged on bolt head one end, is provided with screw thread 5 outside bolt shank 4;
In the present embodiment, bolt head comprises anti-theft device and is arranged on packing ring 3 bottom anti-theft device, and the loosening phenomenon after lock bolt is avoided in the setting of packing ring 3, and improve locking effect and the Safety performance of bolt, packing ring 3 one end is connected with bolt shank 4;
In the present embodiment, anti-theft device comprises single load bearing groove 6, be arranged on the first single load bearing block 1 of single load bearing groove 6 side and be arranged on the second single load bearing block 2 of unidirectional groove 6 opposite side, first single load bearing block 1 and the second single load bearing block 2 are plane of inclination, and cross section is semicircle, first single load bearing block 1 is identical with the second single load bearing 2 block size shape, anti-theft device is one direction stressing device, and then after bolt screws up with a wrench, common wrench cannot be used to be turned on, thus effectively prevent State Grid's equipment by the situation of stealing, reduce the loss of country.
The present embodiment middle washer 3 diameter is greater than bolt shank 4 diameter, can effectively prevent bolt looseness phenomenon, thus improves stability and the Safety performance of bolt.
In the present embodiment, screw thread 5 is right-handed thread, because anti-theft device is the use power apparatus of single direction, and then bolt can only be right-handed thread.
In sum, bolt head of the present invention comprises anti-theft device and is arranged on the packing ring bottom anti-theft device, packing ring one end is connected with bolt shank, anti-theft device comprises single load bearing groove, be arranged on the first single load bearing block of single load bearing groove side and be arranged on the second single load bearing block of unidirectional groove opposite side, first single load bearing block and the second single load bearing block are plane of inclination, and cross section is semicircle, first single load bearing block is identical with the second single load bearing block size shape, and then make bolt after rotation is tightened, cannot be turned on by common spanner, thus effectively reduce State Grid's equipment by the incidence rate of stealing, loss is reduced to country, improve the Safety performance of power equipment.Advantage of the present invention is: structure is simple, reasonable in design, arrange on bolt head a kind of can only single direction locking structure, make bolt tightening after do not disassemble by common wrench.
