Description

Contact type cipher lock

Contact type cipher lock is mainly used in safety cabinet, security door, and the theftproof lock of automobile etc., it is with the mechanical coded lock that replaces electronic type by mode that touches.

Known being locked in the scope of application and using comes with some shortcomings: 1, Suo close capacity is little, and lock easily leaves mutually; 2, the electronic password lock cost is expensive, use to be subjected to placing restrictions on of electricity, and stability is not high, water funk, inflammable; 3, use key operated cylinder lock, key need be carried, inconvenient, easily lose, transreplication, safety be not high; 4, lock of peace, safety are worried again on the security door, and it is expensive that two lock costs are installed, and uses again inconvenient.Based on above-mentioned principle, in conjunction with the advantage of the mode of unblanking of electronic lock, cylinder lock simple in structure, firm, through making great efforts for many years, developed the contact type cipher lock of mechanical system, its major advantage:

1, the number of unblanking does not repeat, and the lock capacity is big; 2, the unblank input of number is touched by digital button or turning handle on the handle with hand, touches behind the numerical selection sign indicating number to touch the button again, and is simple to operation; 3, turning handle can be unblanked after the proper password input was finished; 4, spring key and password combination are a lock, and the lock cost is reduced, and be easy and simple to handle, and safety significantly improves; 5, this kind coded lock is the technological break-through on common cylinder lock, and equipment, technology, the production that can make full use of existing locksmithery are touched by the formula puzzle theft-proof lock; Can make the principle of lock developed again, promote the raising greatly of lock performance.5, this locks not electricity consumption, the scope of application is big.The operating principle of touching by the formula puzzle theft-proof lock is such: utilize the digital button that touches on the handle, make moving of digital button, and the distance that will move what with handle on the number numbering of each digital button be mutually, if this lock is 7 figure places, on then being marked on 7 buttons on the handle respectively from 1～7 digital number, touch by the stroke of each digital button in handle hole the same, and feeler lever that will link to each other with each digital button or feeler lever epirelief dish are different to the feeler lever head apart from length, both determined a reference range arbitrarily, as the long 10m/m of the feeler lever of No. 1 digital button, the long 12mm of the feeler lever of No. 2 digital buttons then, No. 3 digital button feeler lever length is 14mm, by that analogy, the feeler lever of No. 7 digital buttons is long to be 22mm, and the digital disk on the lock core, the position of distribution plate is certain, therefore, if touching by each digital button all is mobile 10mm, then No. 1 digital button can make digital disk move 10mm, No. 2 digital button can make digital disk move 12mm, both many 2mm, No. 3 digital button can make digital disk move 14mm, No. 7 digital button makes digital disk move 22mm, each digital button just number has become sign indicating number the distance that moves like this, and the distribution plate digital disk is corresponding respectively with the number of input, automatically remove to touch successively the number bar of respective number, distance by this number button regulation moves, each digital bar structure length is the same, and the difference of each digital bar displacement is just passed to digital pellet shot from a slingshot, the distance that digital pellet shot from a slingshot is moved is different, the interior pellet shot from a slingshot of contact is with it moved, and the self-locking of releasing lock core and tapered end realize unblanking; The difference of digital pellet shot from a slingshot displacement makes and inputs a code number arbitrarily by mistake, and pellet shot from a slingshot does not open lock with regard to the displacement of mistake in this.By above-mentioned principle, realized the coded lock theory of mechanics, finished purpose of the present invention.
