Abstract
One is anti-unloads anti-theft bolt external member, primarily of bolt, special spanner, taper pin composition, bolt is used for fixing component, time fastening, cylinder on special spanner is inserted in the hole at bolt top, rotates special spanner and make bolt fastener, after tightening, be interference fit into by taper pin in the hole at bolt top, taper pin does not expose.The utility model is by the installation fixed hole of its tip designs and add plunger member, and its top is circular and special construction that is that cannot exert a force, and then realize the function preventing dismounting, have that structure is simple, advantage that is laborsaving, efficient quick of constructing, effectively can cut down finished cost, prevent unloading good anti-theft effect.
Description
Technical field
The utility model relates to securing means technical field, and specifically one is anti-unloads anti-theft bolt external member.
Background technique
Bolt, as fastening piece, is widely used in all trades and professions.Although plain bolt has simple to operate, the advantage of convenient disassembly, it is carried out larceny but to some lawless persons and brings conveniently, as long as namely these lawless persons use common dismantling spanner just can carry out artificial dismounting to bolt, implement theft.In order to effectively prevent this illegal activities, prior art has carried out theft-prevention structure design to bolt, at present, it is modal that anti-to unload anti-theft bolt structure be exactly on the screw rod of bolt, offer an axial cotter way, and by using with the axial pin slot fit be arranged on nut, an anti-theft pin can be inserted in the axial bore that formed by two axial pin grooves by user, thus prevents the improper dismounting of screw bolt and nut.Disclosed in the utility model patent with above-mentioned similar theft-prevention structure has had on China national intellectual property board web, they have been that name is called " antitheft non-return anti-loosening bolt and nut fastening piece ", " a kind of Anti-detaching screw bolts with special-shaped pin " and " grooved wedging-in type straight pin anti-theft bolt " respectively.But these structures exist, and difficulty of processing is large, the deficiency of high cost.
Summary of the invention
The deficiency that the utility model exists for existing Anti-detaching screw bolts, design is a kind of to be prevented unloading anti-theft bolt external member, effectively can reduce costs, reduce difficulty of processing, easy construction, increase work efficiency.
The utility model is realized by following technical measures:
One is anti-unloads anti-theft bolt external member, and primarily of bolt, special spanner, taper pin composition, bolt is used for fixing component, time fastening, cylinder on special spanner is inserted in the hole at bolt top, rotates special spanner and make bolt fastener, after tightening, taper pin is interference fit in the hole at bolt top, taper pin does not expose, and by this technological scheme, the top due to bolt is circular, cannot moment be applied, and then play and anti-unload anti-theft function.
The top of described bolt is at least processed with two holes.
Described special spanner have two round column structures at least.
The beneficial effects of the utility model are: one is anti-unloads anti-theft bolt external member, by the installation fixed hole of its tip designs with add plunger member, and its top is circular and special construction that is that cannot exert a force, and then realize the function preventing dismounting, have that structure is simple, advantage that is laborsaving, efficient quick of constructing, effectively can cut down finished cost, and prevent unloading good anti-theft effect.
Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by an embodiment, and by reference to the accompanying drawings, this programme is set forth.
One is anti-unloads anti-theft bolt external member, form primarily of bolt 1, special spanner 2, taper pin 3, bolt 1 is used for fixing component, as depicted in figs. 1 and 2, time fastening, cylinder on special spanner 2 is inserted in the hole at bolt 1 top, rotate special spanner 2 and make bolt 1 secure component, after tightening, as shown in Figure 3, taper pin 3 is interference fit in the hole at bolt 1 top, taper pin 3 does not expose, and by this technological scheme, the top due to bolt 1 is circular, cannot moment be applied, and then play and anti-unload anti-theft function.
As shown in Figure 2, the top of described bolt 1 is at least processed with two holes.
As shown in Figure 3, described special spanner 2 have two round column structures at least.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
