Manufacturing method of anti-theft lock core
[Technical field]
[0001] This invention involves the technical field of anti-theft lock, specifically a kind of anti-theft lock core.
[Background Technology]
[0002]-General, security doors protect the safety of families. However, the burglary cases happening constantly all over the country have repeatedly proved that only a solid door is far from safe. Because those who enter the house illegally do not need to pry the door at all, but use the unlocking tools and technologies that can be easily bought to open the lock of the anti-theft door and steal in the House calmly. Therefore, the key of the security door is the security door lock, and the core component of the security door lock is the lock core.
[0003] the structure of the traditional lock core is simple and the reopening rate is high, which is easy to cause the phenomenon that two or more keys open the same door, and it is also easy for criminals to open the lock by blind opening method.
[0004] due to the single structure of the lock core of the traditional anti-theft door, it cannot completely prevent the technical unlocking. No matter A- level or B- level lock cylinder, it only plays an anti-theft role for ordinary personnel, while for the employees of the unlocking company and more lawbreakers, as long as there is enough time, there is no lock that cannot be opened.
[0005] the lock core of the traditional anti-theft door is easily reversed by the unlocking tool, and is also easy to be drilled by the electric drill. The reason is that the bomb is used to clamp the rotating core of the lock cylinder, and the rotating core is directly connected with the fork. When the rotating core encounters strong twist, the bomb will be broken and then the rotating core will be rotated, so as to drive the fork to rotate, the door lock will be opened. In addition, the traditional anti-theft door lock core is easy to be drilled by the electric drill, which is also because the rotating core is stuck by the bullet. When the electric drill drilled the rotating core, it is easy to make efforts, and the rotating core is easy to be drilled out, so traditional Guard door lock xin yi quilt electric drill.
[0006] the lock core of the traditional anti-theft door cannot effectively prevent prying and impact. At present, inside and outside of the lock core of the security door, the joint of the two parts is very thin, and there is only one bolt used to fix the lock core on the door lock, which obviously suffers a strong impact or skid, the lock core is easily broken from the middle, or directly pry off from the lock, so that the door lock is easily opened.
[0007] the traditional anti-theft door lock switch is troublesome. Insert the key and move two lock tongues and spring lock tongues. You must turn the key 720 + 110 = 830 degrees. If there are many small pieces of keys, nail clippers, fruit knives and so on the key ring, it will be troublesome if you rotate them twice and need to pour two hands in the middle to unlock them.
