According to the anti-theft nut, an existing pin tumbler lock structure is combined with the nut, and the structure is novel and simple; the anti-theft nut can be prevented from being disassembled, and the anti-theft role is effectively played; the anti-theft nut can be applied to a tire, oil field pumps, transformers and other devices for prevention of thievery.
Description
Technical field
The utility model is the improvement to nut structure.
Prior art
Existing nut structure, profile is hexagonal structure, interior is worm structure, during use, by rotating hexagonal nuts one end, makes nut screw bolt, and fixation is played to fastening effect.For example, automobile tire is fixing.The nut of this structure, in use, is easy to arbitrarily be dismantled by spanner 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 cap is provided.
An anti-theft screw cap, is characterized in that, lock is embedded in to the top of nut, and the top of nut 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 nut top;
On the internal diameter of hexagonal overcoat top, a circle groove is set, is provided with opening jump ring in groove, hexagonal overcoat diameter of bore sectional shape is circular; Hexagonal overcoat is connected by opening jump ring with nut; 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;
Many times, the middle part of nut, in naked state, for the generation that avoids theft better, on the middle part external diameter of square nut, arranges a circle low groove under hexagonal overcoat; Lower overcoat diameter of bore sectional shape is circular; On the internal diameter of lower outside cover top, a circle groove is set; In groove, be provided with opening jump ring, lower overcoat is connected by opening jump ring with nut middle part.
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 are dismantled nut, key 10 to be inserted to lock core hole, rotational lock core 7.6, 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 nut is connected as a single entity, use universal dismounting tool to rotate hexagonal overcoat, i.e. detachable nut.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 nut; Now, lock pins nut, even put outward and use any extracting tool in hexagonal, also nut cannot be dismantled, because now overcoat can only dally along nut by opening jump ring.
No matter nut is in which kind of state, because lower overcoat 11 is connected by opening jump ring 12 with nut middle part, when using extracting tool rotating screw cap middle part, lower overcoat can only dally along nut by opening jump ring, and then cannot dismantle nut, further reach anti-theft function.
The utility model combines the structure of existing bullet lock with nut, 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 cap, is embedded in lock on the top of nut, and the top of nut is lock construction, and bottom is female thread 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;
