Description
The utility model belongs to the architectural hardware field, relates to a kind of mechanical type coding password lock.
Existing lockset type is a lot, roughly is divided into three major types such as common mechanical lock, mechanical dial formula coded lock, electronic password lock.The common mechanical lock cipher amount probability height of unblanking less; Mechanical dial formula coded lock complex structure, anti-dial poor performance, very easy lock pushed aside; Electronic password lock is owing to electronic component performance parameter difference, and it is unreliable to cause unblanking, and environmental suitability is poor, is difficult to behind the password setting revise and cost an arm and a leg.
The purpose of this utility model is to provide a kind of mechanical type coding password lock that overcomes above defective.
The purpose of this utility model is achieved through the following technical solutions: it comprises lock body, lock core, dead bolt and setting stick etc., principal character is its chattering type password coding lock core and corresponding with it contact password coding key, and the CMOS integrated circuit warning device that is connected with the non-password contact of coding lock core.
In the interior cover of password coding lock core and the overcoat one group of above shared pathway is arranged, roller and top spring are arranged in it, N contact is arranged on the inside and outside axial position of cover and along the above common composition encoder matrix of garden group Monday, and sets non-password contact and be connected with two groups of microswitches of CMOS integrated circuit.
Password coding lock core drives bar by lock core, control panel, cam disc and the setting stick that will be fixed on the positioning sleeve connect together, control panel and cam disc are provided with the chute roller, and dead bolt is by spring and promotion dish, and up and down the dead bolt interlock post and the cam disc interlock of ball are set.
Cipher key has one group of above key bar that embeds N contact.
Password coding lock core drives bar by lock core and realizes and the supporting use of any common lock.
In the inside and outside cover passage of password coding lock core, also ball can be set.
The coding of password coding lock core, be delineate on the coat Native digits 0~9 and the combination at random of English 26 letters.
N group of password coding lock core and cipher key, a N contact be the digital coding matrix of composition jointly, and its encoding amount can reach billions of individual, and the probability of unblanking is corresponding reduces to billions of/one.
The utility model has the advantages that the password capacity is big, the coding stochastic variable is big, the probability of unblanking is extremely low, therefore this new type of safe performance is good, coding is simple and direct, can be widely used in vital places such as hotel, the anti-sledge door of dwelling house, automobile, garage, safety cabinet, national treasury, in case wrong can the enforcement of password reported to the police, also can implement CSRC, for even the key loss that prevents trouble before it happens also needn't be changed lock or bitting, recompile as required, this novel also can be supporting with the lockset of any kind, low price.

Embodiment is described in detail in detail in conjunction with the accompanying drawings: it is except that the ordinary construction with general lockset, also unique contact password coding lock core a and contact password coding key b supporting with it, password coding correspondence, and CMOS integrated circuit warning device three parts that are connected with the non-password contact of cipher lock.
In the interior cover 1 of present embodiment password coding lock core a and the overcoat 2 four groups of shared pathway 15 are arranged, four groups of rollers 16 (or ball) and top spring 17 (referring to Fig. 3) are arranged in it, be arranged on interior overcoat 1,2 axial locations and form encoder matrix jointly by 28 contacts, and set the microswitch K of non-password contact and CMOS integrated circuit along garden group Thursday
1, K
2(referring to Fig. 5, A, B, C, D represent four groups among the figure) is connected.
Password coding lock core a drives bar 3 by lock core will be fixed on control panel 8 on the positioning sleeve 4, cam disc 5 and setting stick 10 connect together (referring to Fig. 1), control panel 8 is established chute roller 12 with cam disc 5, and dead bolt 6 is by spring 11 and the promotion dish 13 of ball 7, dead bolt interlock post 9 and cam disc 5 interlocks (referring to Fig. 2) up and down are set.
When setting stick 10 is rotated counterclockwise to position shown in Figure 1, cam disc 5 drives chute roller 12 and rotates downwards in the chute of control panel 8, and by ball 7, promotion dish 13, promote dead bolt 6 door lock is lived, promote the link mechanism of door with door 4 lockings up and down by dead bolt interlock post 9 up and down simultaneously; When setting stick 10 turned clockwise, spring 11 was about to dead bolt 6 and bounces back into original position, and to lower slider, the link mechanism that unclamps door makes it homing to dead bolt interlock post 9 by the interior spring of establishing up and down, and 4 lockings are unclamped.When door is locked by cipher key B, be that cipher lock drives bar 3 rotations, positioning sleeve 4 is also along with rotation, driving chute roller 12 when fixing control panel 8 rotations on it counterclockwise rotates downwards, make 4 all lockings up and down of dead bolt 6 and door, this moment, setting stick 10 rotated never again, thus the time control panel 8 chute below, control panel 8 is by positioning sleeve 4 and cipher lock a connect together (referring to Fig. 1,2).
Cipher lock a drives bar 3 by lock core, realizes and the supporting use of other any common lock.
The key bar of cipher key b is a cross structure, and a forms four groups of corresponding A, B, C, D with password coding lock core, and corresponding fixed contact 14 is arranged on four groups, to realize the encode password of lock core a and the password corresponding (referring to Fig. 3,4) of cipher key b.
The code Design of password coding lock core a is to adopt the combination at random of Native digits 0~9 and English 26 letters, is inscribed on the overcoat 1.The utility model before use to password design such as: to four groups of A of coding lock core a and coding key b, B, C, D carries out the arrangement design (referring to Fig. 6) of Native digits and English alphabet, according to probability theory stochastic variable principle the phrase of numeral or English alphabet composition is encoded, such as: coding china and USA, corresponding natural number coding is 3,8,9,4,1,7,9,4,1,9,0, demonstrate fully the randomness of stochastic variable, thereby reach the immense incomparable of mechanical type coding password lock encoding amount, coding randomness is big, the characteristics that are difficult to decode.
Password coding lock core a and four groups of cipher key b, 28 contacts are formed the digital coding amount jointly and can be reached billions of individually, and the probability of unblanking is corresponding reduces to billions of/one.
