Description
Technical field
The utility model is the improvement to anti-theft screw structure.
Background technique
Existing a kind of anti-theft screw, can prevent from using 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 utility model is the shortcoming overcoming the existence of above-mentioned prior art, provides a kind of anti-theft fastening piece of improvement.
A kind of anti-theft fastening piece, is characterized in that, be made up of two-part; Top is hexagonal part, and bottom is threaded piece; Hexagonal part is connected with threaded piece;
Hexagonal part central part is provided with center hole, and center hole bottom is set to many ribs hole;
Described lock core top arranges a ring annular groove; Annular groove wall is arranged several marble holes; Lock core lower diameter is less than upper diameter, and lock core bottom is set to internal thread;
Described base center is provided with through hole, and through hole internal diameter and lock core lower diameter match, and lock core bottom is placed in the central through bore of base; Base is arranged several spring marble holes, spring marble hole is identical and through with the marble hole quantity on lock core;
The block of rib more than is solid convex, and convex portion arranges outside thread, and outside thread is connected with the internal thread of lock core bottom; Protruding bottom is many prismatics;
Described lock core, base and many ribs block are arranged in hexagonal part, and lock core and base are placed in hexagonal part center hole top, and many ribs block is placed in hexagonal part many ribs hole and slides up and down;
Described base is arranged at least one pin-and-hole, through with the through hole on hexagonal part, be fixedly connected with base and hexagonal part by lateral pin;
First lap pellet is arranged in lock core marble hole; Under second circle pellet is positioned at first lap pellet, withstand on a coil spring simultaneously; One coil spring is positioned at spring marble hole; During lock state, a second circle pellet part is positioned at lock core marble hole, and another part is positioned at the spring marble hole of base; During opening state, the second circle pellet is positioned at the spring marble hole of base completely;
Described threaded piece central upper portion portion arranges the hole of rib more than; Through with many ribs hole of hexagonal part.
The utility model overcomes the shortcoming of prior art, makes structure more reasonable, and hexagonal part thickness thickens, and adds intensity, safe and reliable; Many ribs block of the present utility model is solid construction, and its torsion is increased, and intensity increases, and is used on automobile tire not fragile, effectively reaches anti-theft function.Because the utility model is simple for structure, can be applied on the short and small screw of minimum Φ 8, not fragile in using; Especially be applied on the tire of sedan car, anti-theft effect is more obvious; And 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.
