Abstract
The invention discloses an anti-theft bolt which comprises a bolt head portion and a bolt bar arranged at one end of the bolt head portion. The outside of the bolt bar is provided with threads, the bolt head portion comprises an anti-theft head and a washer arranged at the bottom face of the anti-theft head, one end of the washer is connected with the bolt bar, the anti-theft head is semi-spherical on the whole, and the two sides of the anti-theft head are symmetrically provided with screwing structures. The overall design of the anti-theft bolt is novel, the design structure is simple, and the anti-theft bolt has the advantages that the structure is simple, design is reasonable, the bolt head portion is provided with a structure which can be locked in a single direction and accordingly the bolt cannot be disassembled by a common wrench after being screwed.
Description
Technical field
The present invention relates to bolt technical field, specially refer to a kind of anti-theft bolt.
Background technique
Bolt, nut are one group of common knockdown chain fittings in succession, bolt major part comprises bolt head and bolt shank, and bolt head is often outer regular hexagon Huo Nei regular hexagon mechanism, and the bolt of this structure can be used various Wrenchs to screw flexibly, and then also caused some establishments and the equipment of this structure are stolen, especially power equipment, not only grievous injury national interests, but also produced various potential safety hazards.
Yet for the deficiencies in the prior art, developer be necessary to develop a kind of simple in structure, reasonable in design, on bolt head, arrange a kind of can only single direction locking structure, make a kind of anti-theft bolt that can not disassemble by common wrench after bolt tightening.
Summary of the invention
The problem existing for solving prior art, the object of the invention provide a kind of simple in structure, reasonable in design, on bolt head, arrange a kind of can only single direction locking structure, make a kind of anti-theft bolt that can not disassemble by common wrench after bolt tightening.
For solving above technical problem, the present invention realizes by the following technical solutions: a kind of anti-theft bolt, comprise bolt head and the bolt shank that is arranged on bolt head one end, and described bolt shank outside is provided with screw thread;
Described bolt head comprises antitheft head and the packing ring that is arranged on antitheft bottom surface, and described packing ring one end is connected with bolt shank;
Described antitheft head integral body is hemisphere, and described antitheft bilateral symmetry is provided with and screws structure.
In a preferred embodiment of the invention, the width that screws structure described in is the 0.1-0.3 of integrated anti-theft head width.
In a preferred embodiment of the invention, described packing ring diameter is greater than antitheft diameter, and described antitheft diameter is greater than bolt shank diameter.
In a preferred embodiment of the invention, described screw thread is right-handed thread.
Beneficial effect of the present invention is; Compared with prior art, bolt head of the present invention comprises antitheft head and is arranged on the packing ring of antitheft bottom surface, packing ring one end is connected with bolt shank, antitheft head integral body is hemisphere, and antitheft bilateral symmetry is provided with the unidirectional structure that screws, and then makes bolt after rotation is tightened, cannot be turned on by common spanner, thereby effectively reduce the incidence rate that State Grid's equipment is stolen, to country, reduced loss, improved 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, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is plan view of the present invention.
Fig. 2 is plan view of the present invention.
Fig. 3 is free-body diagram of the present invention.
Numeral and the represented corresponding part title of letter in figure:
1. antitheft 2. packing ring 3. bolt shank 4. screw threads 5. screw structure 6. spanner 7. claws.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in Fig. 1, Fig. 2 and Fig. 3, the present invention is a kind of anti-theft bolt, comprises bolt head and the bolt shank 3 that is arranged on bolt head one end, and bolt shank 3 outsides are provided with screw thread 4;
In the present embodiment, bolt head comprises antitheft 1 and the packing ring 2 that is arranged on antitheft 1 bottom surface, and the loosening phenomenon after lock bolt is avoided in the setting of packing ring 2, has improved locking effect and the Safety performance of bolt, and packing ring 2 one end are connected with bolt shank 3;
In the present embodiment, antitheft 1 integral body is hemisphere, antitheft 1 bilateral symmetry is provided with and screws structure 5, screw structure 5 for unidirectional structure that screws, after bolt is tightened with spanner 6, cannot use common wrench to be turned on, thereby effectively prevented the situation that State Grid's equipment is stolen, reduced national loss.
The width that screws structure 5 in the present embodiment is the 0.1-0.3 of integrated anti-theft head 1 width, screws structure 5 width when larger, affects its mechanical strength of antitheft 1, easily, in the process of screwing, makes antitheft 1 to rupture; If screw structure 5 width hour, be unfavorable for spanner 6 claws 7 clampings, affect its coupling mechanism force.
The present embodiment middle washer 2 diameters are greater than antitheft 1 diameter, and antitheft 1 diameter is greater than bolt shank 3 diameters, thereby have improved the mechanical strength of bolt integral body.
In the present embodiment, screw thread 4 is right-handed thread because be provided with single direction for antitheft 1 screw structure 5, and then bolt can only be right-handed thread.
In sum, bolt head of the present invention comprises antitheft head and is arranged on the packing ring of antitheft bottom surface, packing ring one end is connected with bolt shank, antitheft head integral body is hemisphere, and antitheft bilateral symmetry is provided with the unidirectional structure that screws, and then makes bolt after rotation is tightened, cannot be turned on by common spanner, thereby effectively reduce the incidence rate that State Grid's equipment is stolen, to country, reduced loss, improved the Safety performance of power equipment.Advantage of the present invention is: simple in structure, reasonable in design, on bolt head, arrange a kind of can only single direction locking structure, make can not disassemble by common wrench after bolt tightening.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
