Abstract

The utility model relates to an anti-theft spiral lock. The anti-theft spiral lock consists of a lock core and a lock, and is characterized in that the lock core comprise a lock core external cylinder and a lock core internal cylinder; the lock core external cylinder and the lock core internal cylinder are connected coaxially; a spiral structure is lathed on the inner wall of the lock core internal cylinder; a plurality of marbles are distributed along the spiral structure; and the marbles are matched and connected with a spring. The utility has the technical effects that the structure is simple and the structure of the traditional lockset is changed, thereby effectively preventing thieves from unlocking the lock with steel wire or a universal key, and improving the safety of the lockset.

Description

The theft-protected screw lock

Technical field

The utility model relates to a kind of theftproof lock, relates in particular to a kind of theft-protected screw lock.

Background technology

Lock is a kind of utensil with the anti-theft protection property of locking a door commonly used in the life, in the very long years, along with the continuous development of human civilization; the purposes of lock constantly increases, and the scope of application is wide more, from ancient times to the present; the locking industry of China is all very flourishing, has produced many creativity and innovations.Lockset develops into present various dissimilar intelligence lock by initial wood lock, three springs lock, blade lock.At present, what use always in people's life also all is the lockset that adopts the sub mode of unblanking of lock, in order to strengthen anti-theft effect, locksmiths create various lockset, though the lock structure difference, the mode of unblanking is similar, and lock all is to adopt linear structure, this mode of unblanking is easily adopted iron wire and unlocked by universal key by illegal molecule, and safety factor is not high.

Summary of the invention

The purpose of this utility model is to provide a kind of theft-protected screw lock, this spiral lock solved existing lockset easily by master key or other unlocking tool open may, thoroughly changed the mode of unblanking, anti-theft capability is strong.

The utility model is achieved like this, it is made up of lock core and lock, it is characterized in that lock core comprises cylinder in lock core outside cylinder and the lock core, cylinder in the coaxial connection lock core of lock core outside cylinder, the inwall car curl structure of cylinder in the lock core, along helicoidal structure several pellets shot from a slingshot that distribute, the pellet shot from a slingshot spring that is connected;

The helicoidal structure that described lock matches for the helicoidal structure of lock core inwall, the outer wall of helicoidal structure has several hole slots, and hole slot is corresponding with the pellet shot from a slingshot position.

The front end of the corresponding lock core of the outer wall of lock described in the utility model or middle part one or two pellet shot from a slingshot places have hole slot.

Technique effect of the present utility model is: simple in structure, changed the structure of conventional lock, and prevented that effectively illegal molecule from unblanking with iron wire or omnipotent lock, improve lockset safety.

The specific embodiment

As shown in Figure 1, the utility model is achieved like this, it is made up of lock core and lock, it is characterized in that lock core comprises cylinder 2 in lock core outside cylinder 1 and the lock core, cylinder 2 in the lock core outside cylinder 1 coaxial connection lock core, the inwall car curl structure of cylinder 2 in the lock core, along helicoidal structure several pellets shot from a slingshot 3 that distribute, pellet shot from a slingshot 3 spring that is connected;

As shown in Figure 2, the helicoidal structure that described lock 4 matches for the helicoidal structure of lock core inwall, the outer wall of helicoidal structure has several hole slots 5, and hole slot 5 is corresponding with pellet shot from a slingshot 3 positions.The front end of the corresponding lock core of the outer wall of lock or middle part one or two pellet shot from a slingshot places have hole slot.During use, helical form is locked in the sub-precession lock core in the cylinder, enter in the sub-front end hole slot of lock to the pellet shot from a slingshot of lock core front end and get final product, at this moment the turn lock core unblanks to get final product.

Claims (2)

1. a theft-protected screw is locked, it is made up of lock core and lock, it is characterized in that lock core comprises cylinder in lock core outside cylinder and the lock core, cylinder in the coaxial connection lock core of lock core outside cylinder, the inwall car curl structure of cylinder in the lock core, along helicoidal structure several pellets shot from a slingshot that distribute, the pellet shot from a slingshot spring that is connected;

The helicoidal structure that described lock matches for the helicoidal structure of lock core inwall, the outer wall of helicoidal structure has several hole slots, and hole slot is corresponding with the pellet shot from a slingshot position.
