Background technology

Security door is the guarantee of life staying idle at home safety, and for security door, many customers, owing to electronic anti-theft door being lacked to deep understanding, have often only focused on the quality of safe-guard door lock panel material, seldom pay close attention to the problem of door lock body.And door lock body is only the place of security door most critical.No matter security door has how many lock points, but all there is interlock with lock body in these lock points, and lock body is opened, and door is just opened.As everyone knows, the quality of judgement security door, except will seeing shop front quality material quality, most important is exactly door lock body, although be slight one, its quality is often directly connected to household, even the safety of lives and properties.Door lock body is the heart of security door, there is no this heart, and this security door just performs practically no function.A perfect lock body of design can be described as any one master-hand that unblanks and does not open and easy to use.Along with the raising of people's awareness of safety, people are also high standards all the more to antitheft requirement.The quality of a security door of judgement, except seeing the material of anti-theft door plate, most important has been exactly the lock body of security door.Offender, if the words of the door of looking on the bright side of things generally can not select door-plate to destroy and to enter, but selects to set about from lock body, so door lock body but becomes the factor of security door most critical.There is technological deficiency in existing lock body, the lock cylinder cooperation that it can only use is opened the door.Key fallen door just do not open.2. go home to open the door and will take out key, key is many must be looked for.Key injects out rear 2 circles that first turn and opens and lock, then turns 2 circles and just can open the door.Going out closes the door is also so, and door is shut rear slotting key and turned 2 circles and could lock locking.It is exposed at face outdoors having this lock core again.Although the internal construction

space " or somewhat curved cylinder space.It is with key or special tool(s), all pellets all to be headed into topmost that upper top formula is opened, and by means of the terrace between torsion and inside and outside lock core marble hole, under the effect of spring force, interior pellet falling, outer pellet is hindered outside internal cylinder, thus opened lock.For current high-grade antitheft sylinder on the market, though because structure is not quite similar, its technical opening Method and kit for is also not quite similar, and because it is " upper top formula is opened ", its basic principle is all the same.General is all key corresponding to lock core.Key inserts lock core, " tooth " that key height is different, corresponding inner copper pellet different in size.Their length just makes the other end of interior pellet concordant with internal cylinder hole, this just means, insert an other key, difference due to " tooth " shape, will cause in some pellet to expose or recessed, as long as one is exposed or recessed, just can block internal cylinder and can not rotate, just can not unblank.The different length of pellet and combination, corresponding different keys, makes a key can only open a lock.Because lock is to manufacture in batches, different pellets and combination are limited, and the lock of batch production, have the probability of repetition, and the probability that key is driven 2 locks is difficult to avoid, the size of probability depend on marble amount and combination number.Common spring lock generally has 4 to 5 groups of pellets, and shaped as key bit nipper end tooth is dark, and the depth differs greatly.If fake and forged antitheft sylinder lacks pellet, can pull out and press observation or twitch key listening and crack with fine needle.Lock is conflict with unblanking, and lock kind since invention is a lot, is still constantly having more senior electronic lock so far, and Fingerprint Lock invents.Along with the application of electronics, electromechanics and information technology, theftproof lock enters electronic age, and original cylinder lock, owing to limiting in structure, has been difficult to meet current social management and antitheft requirement.If prior art electronic anti-theft lock need to change left and right directions, need professional to open whole lock body, take out dead bolt, change a direction and be loaded into again.Can produce so mobile other parts and can not reinstall former state, cause using.The general touch switch of use in the market, this switch is
