Description

Anti-theft lock

Technical Field

The invention relates to the technical field of locks.

Background

The existing anti-theft lock basically allows unmatched unlocking tools to be inserted into a key hole to pry a marble to find the unlocking position of the marble for attempting unlocking, lawless persons use unmatched unlocking tools such as iron wires, flat iron needles and the like to be inserted into the key hole to pry the marble to find the unlocking position of the marble for attempting unlocking, and finally the existing anti-theft lock can basically unlock, and the existing anti-theft lock is poor in safety and cannot well protect the property safety of people.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the technical scheme of the anti-theft lock, the marble is provided with the groove for inserting the unlocking tool, the grooves between the two marbles are staggered when unlocking, the design mode effectively prevents lawless persons from prying the marble to find the unlocking position of the marble through unmatched unlocking tools such as iron wires, flat iron pins and the like, the safety is greatly improved, and the property safety of people can be well protected.

The invention adopts the following technical scheme: the anti-theft lock comprises a lock core, a lock core shell and a marble, and is characterized in that: the lock core is inserted into a lock core shell, the lock core is provided with a marble groove for mounting marbles, the marbles are mounted in the marble groove and can movably protrude out of the lock core, the lock core shell is provided with a groove I and a groove II, the lock core is arranged between the groove I and the groove II, and when the marbles protrude out of the lock core and enter the groove I and/or the groove II, the lock core is locked.

Further, a groove III for inserting a key is arranged on the pin.

Further, the groove III forms a channel when the groove III is not inserted with a key.

Further, when the key is not inserted to move the pin tumbler to retract into the lock cylinder and not to protrude out of the lock cylinder, the gap of the through channel is reduced or closed.

The lock further comprises a spring, wherein the spring is installed in the lock core and controls the pin tumbler to reset, and a bulge which is propped against one end of the spring is formed on one side of the pin tumbler.

Further, at least 2 marbles are arranged in the lock core.

Further, when the plug is twisted without a key inserted, the pins closer to the entry of the keyway will hit the left and/or right wall of the groove I and/or groove II before the pins farther from the entry of the keyway.

Furthermore, a clamp spring for preventing the lock cylinder from being separated from the lock cylinder shell is installed at one end of the lock cylinder.

Furthermore, at least 2 springs of one marble control the marble to reset.

Further, still include the bolt, the bolt top is in the one end of spring, prevents that the spring from deviating from the lock core.

The invention has the following beneficial effects:

when the lock is unlocked by the technology, all the marbles need to be moved to retract into the lock core to unlock because the positions of the marbles to unlock need to be found, and the positions of the grooves III between the marbles can be staggered when the marbles are moved to retract into the lock core, so that gaps of the key hole can be reduced or closed after the positions of the grooves III between the marbles are staggered, the finding of the positions of other marbles to unlock is hindered, the capacity of preventing the technology from being opened is greatly enhanced, and the property safety of people can be better protected.

Detailed Description

Referring to fig. 1-5, an anti-theft lock includes a lock cylinder 1, a lock cylinder housing 2 and a pin tumbler 3, and is characterized in that: the lock core 1 is inserted into a lock core shell 2, the lock core 1 is provided with a marble groove 11 for mounting marbles 3, the marbles 3 are mounted in the marble groove 11, the marbles 3 can movably protrude out of the lock core 1, the lock core shell 2 is provided with a groove I21 and a groove II 22, the lock core 1 is arranged between the groove I21 and the groove II 22, the marbles 3 move between the groove I21 and the groove II 22, the groove mouths of the groove I21 and the groove II 22, which are close to a key inlet, are smaller than the groove mouths far away from the key inlet, or the upper ends and the lower ends of the two marbles 3, which are close to the key inlet, are larger than the two ends of the marbles 3, which are far away from the key inlet, the two marbles, which are close to the key inlet, are closer to the left inner wall or the right inner wall of the groove I21 or the groove II 22 than the other marbles 3, the other marbles 3 are in a suspended state, and when the marbles 3 protrude out of the lock core 1, the protruding part of the marble 3 does not touch the lock cylinder shell 2, so the suspended marble 3 is not easy to find the unlocking position, the technical unlocking prevention capability is greatly enhanced, and when the marble 3 protrudes out of the lock cylinder 1 and enters the groove I21 and/or the groove II 22, the lock cylinder 1 is locked.

Wherein, a groove III 31 for inserting the key 4 is arranged on the pin 3.

Wherein, when the groove III 31 is not inserted with the key 4, the grooves III 31 of all the pins 3 in the lock core 1 are arranged to form a keyhole channel.

When a key 4 is not inserted to move the marble 3 into the lock core and does not protrude out of the lock core 1, the positions of the grooves III 31 between the marbles 3 are staggered, the through channel gap of the key hole is reduced or closed, and when a lawless person wants to pry the marble 3 by using unmatched unlocking tools such as iron wires, flat iron pins and the like to unlock the lock without protruding out of the lock core 1, the positions of the grooves III 31 between the marbles 3 are staggered, the through channel gap of the key hole is also reduced or closed, so that the situation that the lawless person can pry the marble 3 by using the unmatched unlocking tools such as iron wires, flat iron pins and the like to find the unlocking position of the marble 3 is prevented, the technical unlocking prevention capacity is greatly enhanced, and the property safety of people can be better protected.

The lock core further comprises a spring 5, the spring 5 is installed in the lock core 1, the spring 5 controls the marble 3 to reset, and a protrusion 32 which is pressed against one end of the spring 5 is formed on one side of the marble 3.

Wherein, at least 2 marbles 3 are arranged in the lock core 1.

Wherein when the plug 1 is twisted without the key 4 inserted, the pins 3 closer to the entry of the keyway hit the left and/or right wall of the groove I21 and/or the groove II 22 before the pins 3 farther from the entry of the keyway.

Wherein, a clamp spring 6 for preventing the lock core 1 from being separated from the lock core shell 2 is arranged at one end of the lock core 1.

Wherein, the marble 3 has at least 2 springs 5 to control the marble 3 to reset.

The lock core further comprises a bolt 7, wherein the bolt 7 is abutted to one end of the spring 5, so that the spring 5 is prevented from falling into the groove I21 or the groove II 22 after being separated from the lock core 1, and other parts are prevented from being damaged.
