Abstract
The utility model discloses a kind of anti-theft bolt, comprise bolt head and the bolt shank being arranged on bolt head one end, outside described bolt shank, be provided with screw thread; Described bolt head comprises antitheft head and is arranged on the packing ring of antitheft head bottom surface, and described packing ring one end is connected with bolt shank; Described antitheft head entirety is hemisphere, and described antitheft head bilateral symmetry is provided with and screws structure.Comparatively novel in the utility model global design, and project organization is comparatively simple, concrete advantage 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.
Description
Technical field
The utility model relates to bolt technical field, is related specifically to a kind of anti-theft bolt.
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 anti-theft bolt that common wrench disassembles.
Model utility content
For solving prior art Problems existing, the utility model object 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 anti-theft bolt that common wrench disassembles.
For solving above technical problem, the utility model comes to be realize by the following technical solutions: a kind of anti-theft bolt, 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 antitheft head and is arranged on the packing ring of antitheft head bottom surface, and described packing ring one end is connected with bolt shank;
Described antitheft head entirety is hemisphere, and described antitheft head bilateral symmetry is provided with and screws structure.
In a preferred embodiment of the present utility model, described in screw structure width be the 0.1-0.3 of integrated anti-theft head width.
In a preferred embodiment of the present utility model, described gasket diameters is greater than antitheft head diameter, and described antitheft head diameter is greater than bolt shank diameter.
In a preferred embodiment of the present utility model, described screw thread is right-handed thread.
The beneficial effects of the utility model are; Compared with prior art, bolt head of the present utility model comprises antitheft head and is arranged on the packing ring of antitheft head bottom surface, packing ring one end is connected with bolt shank, antitheft head entirety is hemisphere, and antitheft head bilateral symmetry is provided with and unidirectionally screws structure, and then makes 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, reduce loss to country, improve the Safety performance of power equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment 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 embodiments more of the present utility model, 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. 1 is plan view of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is free-body diagram of the present utility model.
Numeral and the corresponding part title represented by letter in figure:
1. antitheft 2. packing ring 3. bolt shank 4. screw threads 5. screw structure 6. spanner 7. claw.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, the utility model is a kind of anti-theft bolt, comprises bolt head and the bolt shank 3 being arranged on bolt head one end, is provided with screw thread 4 outside bolt shank 3;
In the present embodiment, bolt head comprises antitheft 1 and is arranged on the packing ring 2 of antitheft 1 bottom surface, and the loosening phenomenon after lock bolt is avoided in the setting of packing ring 2, and improve locking effect and the Safety performance of bolt, packing ring 2 one end is connected with bolt shank 3;
In the present embodiment, antitheft 1 entirety is hemisphere, antitheft 1 bilateral symmetry is provided with and screws structure 5, screw structure 5 for unidirectional structure that screws, after bolt spanner 6 is tightened, 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 width screwing structure 5 in the present embodiment is the 0.1-0.3 of integrated anti-theft head 1 width, screw structure 5 width larger time, affect its mechanical strength of antitheft 1, easily in the process of screwing, make antitheft 1 to rupture; If screw structure 5 width less time, be unfavorable for that spanner 6 claw 7 clamps, affect its coupling mechanism force.
The present embodiment middle washer 2 diameter is greater than antitheft 1 diameter, and antitheft 1 diameter is greater than bolt shank 3 diameter, thus improves the mechanical strength of bolt entirety.
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 utility model comprises antitheft head and is arranged on the packing ring of antitheft head bottom surface, packing ring one end is connected with bolt shank, antitheft head entirety is hemisphere, and antitheft head bilateral symmetry is provided with and unidirectionally screws structure, and then makes 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, reduce loss to country, improve the Safety performance of power equipment.Advantage of the present utility model 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.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
