Abstract
An anti-theft screw is characterized in that a lock is embedded into the upper portion of the screw, the upper portion of the screw is of a lock structure, the lower portion of the screw is of a thread structure, the lock structure is composed of a pin tumbler lock cylinder and a spring bolt, a transverse hole is formed below the lock cylinder, the spring bolt is arranged inside the transverse hole, a groove is formed in the spring bolt, a shifting column arranged at the bottom of the lock cylinder is clamped inside the groove in the spring bolt, a circle of groove is formed in the outer diameter of the upper portion of the screw, a circle of groove is formed in the inner diameter of the upper portion of a hexagonal outer sleeve, opening clamping springs are formed in the groove, the hexagonal outer sleeve is connected with the screw through the opening clamping springs, a lock hole is formed in the side wall of the hexagonal outer sleeve, and the lock hole is communicated with the transverse hole. According to the anti-theft screw, an existing pin tumbler lock structure is combined with the screw, and the structure is novel and simple; after being locked, the anti-theft screw can be prevented from being disassembled by any disassembling tool, and the anti-theft role is effectively played; the cost is low, popularization is easy, and the application range is wide; the anti-theft screw can be applied to a tire for prevention of thievery, and can also be applied to oil fields, various pumps, transformers and other devices for prevention of thievery.
Description
Technical field
The utility model is the improvement to screw-rod structure.
Prior art
Existing screw-rod structure, one end is hexagonal nuts structure, the other end is worm structure.During use, by rotating hexagonal nuts one end, screw rod is entered in screw, to being fixed, body plays fastening effect.For example, automobile tire is fixing.The screw rod of this structure, in use, is easy to arbitrarily be dismantled by instruments such as spanners by people, causes tire and other objects to lose, and to user, causes economic loss.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming that above-mentioned prior art exists, and a kind of improved anti-theft screw is provided.
An anti-theft screw, is characterized in that, lock is embedded in to the top of screw rod, and 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, and a dead bolt is set in cross-drilled hole, has groove on dead bolt; The post of stirring that lock core bottom arranges is stuck in the groove on dead bolt;
One circle groove is set on the external diameter of screw rod top;
On the internal diameter of hexagonal overcoat top, a circle groove is set, is provided with opening jump ring in groove, hexagonal overcoat inner hole section is shaped as circle; Hexagonal overcoat is connected by opening jump ring with screw rod; On hexagonal sleeve side wall, have a lockhole, lockhole is communicated with cross-drilled hole, the through hole intrinsic displacement of dead bolt after connection.
The utility model adopts existing billiards lock structure.Existing billiards lock structure comprises locating stud, pellet, spring and the composition of inserting; Locating stud, pellet are all by spring and insert spacing; Locating stud is fixed in restraining groove.
The utility model working principle is, when needs dismantling screw, key 10 to be inserted to lock core hole, rotational lock core, according to the working principle of bullet lock, the locating stud 9 on lock core is motionless, and lock core rotates, by stirring post 7.1, drive dead bolt 4 displacements, dead bolt enters in the lockhole 8.2 on hexagonal overcoat 8, now, hexagonal overcoat and screw rod is connected as a single entity, use universal dismounting tool to rotate hexagonal overcoat, get final product dismantling screw.According to the principle of lockset, key now can not be extracted, a corresponding lock of key.
When needs are antitheft, key is back rotated, by stirring post 7.1, drive dead bolts to reset, dead bolt departs from the lockhole that hexagonal puts outward, and hexagonal overcoat is separated with screw rod; Now, lock pins screw rod, even put outward and use any extracting tool in hexagonal, also screw rod cannot be dismantled, because now, hexagonal overcoat can only dally along screw rod by opening jump ring.
The utility model combines the structure of existing bullet lock with screw rod, novel structure, simple.After the utility model locking, can prevent from using any extracting tool to dismantle, effectively played anti-theft function; And with low cost, easily universal, applied range; Can be applicable on tire antitheftly, also can be applicable to antitheft on the equipment such as oil field, various pump class, transformer.

Embodiment
An anti-theft screw, the top that lock 7 is embedded in to screw rod 1, the top of screw rod is lock construction, bottom is worm structure;
Described lock construction adopts existing billiards lock structure, bullet lock master 7.6 and dead bolt 4, consists of.Lock 7, with bullet lock master 7.6, is provided with restraining groove 7.2, pellet 7.3, spring 7.4 and inserts 7.5 in lock core; Position limit pin 9 is stuck in restraining groove 7.2; Position limit pin 9 and pellet 7.3 all by spring 7.4, insert 7.5 spacing.
The below of lock core is a cross-drilled hole 1.3, and a dead bolt 4 is set in cross-drilled hole, has groove 4.1 on dead bolt; The post 7.1 of stirring that lock core bottom arranges is stuck in the groove 4.1 on dead bolt;
One circle groove 1.4 is set on the external diameter of screw rod top;
On hexagonal overcoat 8 top internal diameters, a circle groove 8.1 is set, is provided with opening jump ring 6 in groove, hexagonal overcoat inner hole section is shaped as circle; Hexagonal overcoat is connected by opening jump ring 6 with screw rod; On hexagonal sleeve side wall, have a lockhole 8.2, lockhole is communicated with cross-drilled hole 1.3.
In described lock core structure, dead bolt 4 is cylindrical body, can make nut be connected with upper overcoat more firm, unsuitable slippage, and dismounting nut is convenient.
