Abstract
An anti-theft nut is composed of a hexagonal outer sleeve and a cylindrical thread inner sleeve. The thread inner sleeve is of an internal thread structure. The cross-section shape of an inner hole of the hexagonal outer sleeve is circular. A lock is embedded into the outer side face of the hexagonal outer sleeve. A lock structure is composed of a pin tumbler lock cylinder and a spring bolt. A spring bolt hole is formed in the hexagonal outer sleeve perpendicular to the lock cylinder. The spring bolt is arranged inside the spring bolt 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 thread inner sleeve, a circle of groove is formed in the inner diameter of the upper portion of the hexagonal outer sleeve, opening clamping springs are formed in the groove in the inner diameter, and the hexagonal outer sleeve is connected with the thread inner sleeve through the opening clamping springs. A lock hole is formed in the side wall of the thread inner sleeve, and the lock hole is communicated with the spring bolt hole in the hexagonal outer sleeve. According to the anti-theft nut, an existing lock structure is combined with the nut, the structure is simple, the anti-theft nut can be prevented from being disassembled, the anti-theft role is effectively played, and the anti-theft nut 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 nut structure.
Prior art
Existing nut structure, profile is hexagonal structure, interior is female thread structure, during use, by rotating hexagonal one end, makes nut screw bolt, plays 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 nut is provided.
A two-layer anti-theft nut, is characterized in that, hexagonal overcoat and cylindrical thread inner sleeve 8, consists of, and screw thread inner sleeve is female thread structure; Hexagonal overcoat inner hole section is shaped as circle; Lock 7 is embedded in the outer side surface of hexagonal overcoat;
Described lock construction can adopt existing billiards lock structure, bullet lock master and dead bolt, consists of;
In the hexagonal perpendicular to lock core, put outward, a lock-tongue hole is set; One dead bolt is set in lock-tongue hole, on dead bolt, has groove; The post of stirring that lock core bottom arranges is stuck in the groove on dead bolt;
On the external diameter of screw thread inner sleeve top, a circle groove is set;
On the internal diameter of hexagonal overcoat top, a circle groove is set, is provided with opening jump ring in groove, hexagonal overcoat is connected by opening jump ring with screw thread inner sleeve; On screw thread sidewall of the inside race, have a lockhole, the lock-tongue hole that lockhole puts outward with hexagonal is communicated with, the hole intrinsic displacement that dead bolt is being communicated with.
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, lock core rotates, by the post 7.1 of stirring on lock core, drive dead bolt 4 displacements, dead bolt enters in the lockhole 8.2 of screw thread inner sleeve 8, has limited screw thread inner sleeve and has rotated, now, screw thread inner sleeve and hexagonal overcoat are integrated, and use general utility 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 the post 7.1 of stirring on lock core, drive dead bolts to reset, dead bolt departs from the lockhole of screw thread inner sleeve, and hexagonal overcoat is separated with screw thread inner sleeve; Now, even put outward and use any extracting tool in hexagonal, also cannot be by nut dismounting, because now hexagonal overcoat can only dally along screw thread inner sleeve by opening jump ring.
The utility model combines the structure of lock with nut, simple in structure, after the utility model locking, can prevent from using any extracting tool to dismantle, and has effectively played anti-theft function; And cost is low, easily universal, applied range; Can be applicable on tire antitheftly, also can be applicable on the equipment such as oil field, various pump class, transformer antitheft.

Embodiment
A two-layer anti-theft nut, is characterized in that, hexagonal overcoat 1 and cylindrical thread inner sleeve 8, consists of, and screw thread inner sleeve is female thread structure; Hexagonal overcoat inner hole section is shaped as circle; Lock 7 is embedded in the outer side surface of hexagonal overcoat;
Described lock construction can adopt existing billiards lock structure, bullet lock master 7.6 and dead bolt 4, consists of;
Existing bullet lock master structure, 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.
In the hexagonal perpendicular to lock core, put outward, a lock-tongue hole 1.3 is set; One dead bolt 4 is set in lockhole, on dead bolt, has groove 4.1; The post 7.1 of stirring that lock core bottom arranges is stuck in the groove interior 4.1 on dead bolt;
On the external diameter of screw thread inner sleeve top, a circle groove 8.1 is set;
On the internal diameter of hexagonal overcoat top, a circle groove 1.1 is set, is provided with opening jump ring 6 in groove, hexagonal overcoat is connected by opening jump ring with screw thread inner sleeve; On screw thread sidewall of the inside race, have a lockhole 8.2, the lock-tongue hole 1.3 that lockhole 8.2 puts outward with hexagonal is communicated with.
Hexagonal below described lock core puts outward a parallel spring hole 1.2 is set, and stage clip 2 is positioned at the bottom of spring eye, and the stage clip the other end is spacing by steel ball 3; Steel ball withstands on dead bolt, and spring eye available 11 sealings of inserting in bottom, avoid dead bolt to move.
In described lock core structure, dead bolt is cylindrical body, can make hexagonal overcoat be connected with screw thread inner sleeve more firm, unsuitable slippage, and dismounting nut is convenient.。
