One is anti-unloads anti-loose anti-theft hexagon socket head cap screw device, primarily of bolt, sealing plug, tension pin, first check pin, second check pin composition, fastening complete after, sealing plug is knocked with hammer, along with going deep into gradually of sealing plug, it is descending that the taper end of sealing plug will promote tension pin, sphenoid surface in tension pin is by promotion second check pin, first check pin moves left and right respectively, and then make the first check pin, the tight flank of thread of pointed side pressure of the second check pin, play the effect preventing from loosening, after installation, the end face of sealing plug and the hexagonal end face of bolt, stub end due to bolt is circular, and do not apply the space of power, and then play the effect preventing from dismantling, reach antitheft object.The utility model has that structure is simple, advantage that is laborsaving, efficient quick of constructing, and can effectively cut down finished cost, and anti-ly to unload, locking, good anti-theft effect.
Description
Technical field
The utility model relates to securing means technical field, and specifically one is anti-unloads anti-loose anti-theft hexagon socket head cap screw device.
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 utility model is for the existing anti-deficiency of unloading chek bolt and existing, and design is a kind of to be prevented unloading anti-loose anti-theft hexagon socket head cap screw device, 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-loose anti-theft hexagon socket head cap screw device, primarily of bolt, sealing plug, tension pin, first check pin, second check pin composition, bolt is used for fixing component, first check pin, second check pin is arranged in the through hole of bolt respectively, and do not expose, tension pin is arranged in the blind hole of bolt, the sphenoid surface of tension pin and the first check pin, the sphenoid surface contact of the second check pin, during clamping bolt, conventional inner hexagon spanner is used to carry out clamping bolt, fastening complete after, sealing plug interference is installed to the stub end of bolt, the taper end of sealing plug is installed in the central blind hole of bolt, sealing plug is knocked with hammer, along with going deep into gradually of sealing plug, it is descending that the taper end of sealing plug will promote tension pin, sphenoid surface in tension pin is by promotion second check pin, first check pin moves left and right respectively, and then make the first check pin, the tight flank of thread of pointed side pressure of the second check pin, play the effect preventing from loosening, after installation, the end face of sealing plug and the hexagonal end face of bolt, stub end due to bolt is circular, and do not apply the space of power, and then play the effect preventing from dismantling, reach antitheft object.
The first described check pin, the second check pin all have sphenoid surface in one end, and the other end is horn structure.
describedthe lower end of tension pin 3 is with sphenoid surface.
The beneficial effects of the utility model are: one is anti-unloads anti-loose anti-theft hexagon socket head cap screw device, by sealing plug and tension device, realize the function preventing from dismantling and prevent to loosen, have that structure is simple, advantage that is laborsaving, efficient quick of constructing, can effectively cut down finished cost, and anti-to unload, locking, good anti-theft effect.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
