Description
Technical field
The utility model is the improvement to anti-theft screw structure.
Prior art
Existing a kind of anti-theft screw, can prevent from using any extracting tool to dismantle, effectively serve anti-theft function; It can be applicable on tire antitheft, and what also can be applicable on the equipment such as oil field, various pump class, transformer is antitheft.Its structure is, lock is embedded in the top of screw rod, the top of screw rod is lock construction, and bottom is worm structure.Described lock construction is by having bullet lock master and dead bolt forms; The below of lock core is a cross-drilled hole, arranges a dead bolt, dead bolt has groove in cross-drilled hole; In stirring of arranging bottom the lock core groove that post is stuck on dead bolt; Screw rod top external diameter is arranged a circle groove; Hexagonal overcoat upper inner diameter is arranged a circle groove, be provided with opening jump ring in groove, hexagonal overcoat is connected by opening jump ring with screw rod; Hexagonal sleeve side wall has a lockhole, lockhole is communicated with cross-drilled hole, lateral displacement in the through hole of dead bolt after connection.
The anti-theft screw of this structure, its shortcoming is, because lock core is positioned at the top of screw rod, screw rod connects hexagonal overcoat outward, in fact has two-layer parcel outside lock core; And dead bolt is transverse shifting; If this structure to be made the screw being less than Φ 14, the screw being less than Φ 14 of so this structure cannot be produced at all.Dead bolt cannot move because locational space relation is narrow and small; If this structure be applied on small size screw, undersized like this lock core structure, also almost cannot install even if produce, and also can be easy in actual use fracture, substantially can not play due anti-theft function.Because the bolt of this structure is open keyhole on hexagonal sleeve side wall, middle hexagonal overcoat is used very easily to rupture.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming that above-mentioned prior art exists, provides a kind of anti-theft screw being less than Φ 14.
A kind of anti-theft screw, is characterized in that, be made up of two-part; Top is hexagonal part, and bottom is threaded piece; Hexagonal part is fixedly connected with threaded piece;
Threaded piece top arranges spring eye, and hole is built with spring, and the top of spring eye is divided into many ribs hole, and its cross section is many prismatics; The pitch-row in many ribs hole is greater than the diameter of spring eye; Spring eye and many ribs hole coaxial line;
Hexagonal part top is provided with lockhole, is provided with lock in lockhole; With lockhole through rib more than hole, identical with many ribs hole of threaded piece; The length in lockhole and many ribs hole is greater than the length of lock core; Many ribs hole of lock core and hexagonal part, many ribs hole coaxial line of threaded piece; Many ribs block and many ribs hole shape match, and many ribs block moves up and down in many ribs hole;
Lock shell is fixedly connected with hexagonal part by fixing pin.
Utility model works principle is, when needs dismounting anti-theft screw, key is inserted lock core hole, rotational lock core, by the rotation of lock core, promote many ribs block to bottom offset, many ribs block enters in many ribs hole of threaded piece, now, threaded piece and hexagonal part is connected as a single entity, use universal dismounting tool to rotate hexagonal part, get final product dismantling screw.
When needing antitheft, back rotated by key, make many ribs block moves reset by spring, many ribs block departs from threaded piece, and hexagonal part is separated with threaded piece; Now, even if use any extracting tool on hexagonal part, also anti-theft screw cannot be dismantled, because hexagonal part is now just originally in rotation, and threaded piece is motionless.
The utility model not only can prevent from using any extracting tool to dismantle, and effectively serves anti-theft function, and structure more advantages of simple.Many ribs block structured advantage not easily fractures in the application, and owing to being move up and down, can being applied on the short and small screw such as Φ 14, Φ 12, using more safe and reliable, expand using scope; Especially be applied on the tire of sedan car, not fragile, anti-theft effect is more obvious; And with low cost, easily popularize, applied range; Can be applicable on tire antitheft, what also can be applicable on the camp equipments such as oil field, various pump class, transformer is antitheft.
