Description

Password night lock

The utility model relates to daily living article, and the cylinder lock of Cipher mechanism is particularly arranged.

Cylinder lock is the commodity that people are very familiar to, cylinder lock on the market has medium-sized, the dual fail-safe type is also arranged, all be that a key inserts in the lock core when they are unblanked, as long as can just can open lock by rotational lock core, this lock just may be prepared key by stealer, lock is opened, so safety not enough.

The purpose of this utility model is for people provide a kind of fool proof reliable password night lock, should use key when unblanking, and knows that again password just can open lock.

Technical solution of the present utility model is to increase by a cover password interlinked mechanism between cylinder of spring lock and dead bolt, its composition is to go up the sign indicating number circle, following code wheel, two breach wheels, the reed wheel, the core wheel that is fixed together with following code wheel, be arranged on the Lian Baoxin of mounting spring above the wheel in-core, be contained in the wheel sign indicating number ring of the end of Lian Baoxin, sign indicating number circle and breach wheel in the binding, the Xiao Zi of following code wheel and breach wheel, can insert breach and take turns company's door bolt of big breach, the connecting rod that connects door bolt and dead bolt, the spring of cover connecting rod, decide spring support and be fixed on compositions such as swing link on the shifting shaft that has outer bracelet.On the excircle of last Ma Quan, following code wheel several breach are arranged, there are several can hold the hole of Xiao Zi on the plane, the logical key of reed wheel is that core wheel cooperates, circle has an interior double wedge in the last yard circle, when the core wheel inhour is rotated, the and then rotation of reed wheel, the reed that is fixed on the reed withstands counter-clockwise rotation of the moving upward sign indicating number of convex cingulum circle; The tip spacer falls into the breach of the outer circle of sign indicating number circle, on one side breach has a support parallactic angle, another side arc transition; The round end spacer falls into down in the breach of the outer circle of code wheel, the bright limit arc transition of breach.

The utility model novel structure, easy to use, safe and reliable.

Below in conjunction with accompanying drawing the utility model is further described.

The utility model is made up of dead bolt (1), lock core (19), base plate (29), shell (26), handwheel (25) and a cover password interlinked mechanism as can be seen from above-mentioned view.The composition of this mechanism is: have one one end that the breach that can insert swinging plate (20) is arranged, the other end has the hole that can match with wheel sign indicating number ring (10), spring (45) is enclosed within the Lian Baoxin (13) at middle part, Lian Baoxin (13) is placed in the core wheel (38), because the effect of wheel sign indicating number ring (10) and spring (45), can the dealing activity; One end of core wheel (38) has a groove, and wheel sign indicating number ring (10) can be movable in groove, and the other end is fixing with following code wheel (21); Breach wheel (23) is enclosed within on the core wheel (38), is associated in following code wheel (21) by Xiao (22), and following code wheel (21) rotates and can drive breach wheel (23); Breach wheel (11) also is enclosed within on the core wheel (38), has been associated in by Xiao (24) and last sign indicating number circle (9), and last code wheel (9) rotates just can drive breach wheel (11); Reed wheel (6) cooperates with core wheel (38) by key Xiao (47), and the reed (7) that is fixed on reed wheel (6) can withstand on interior double wedge (39) in the sign indicating number circle (9), and reed wheel (6) inhour can drive when rotating yard encloses (9) rotation; Company's door bolt (5) of the big breach (36) on the alignment notch wheel (11,23) links to each other with dead bolt (1) by connecting rod (30), and spring (2) is enclosed within on the connecting rod (30), and is limited in and decides between spring support (3) and the dead bolt (1); Dead bolt (1) can slidably reciprocate in lock bolt sleeve (14); Swing link (4) is fixed on the shifting shaft (12), and outer bracelet (16) is connected an end of shifting shaft (12), rotates outer bracelet (12) and can make swing link (4) promote to connect door bolt (5), makes dead bolt (1) indentation; On the outer circle of last sign indicating number circle (9), following code wheel (21) 10 breach are arranged, as increasing the password number, the breach number can increase, and 10 holes that can hold Xiao Zi are arranged on the plane, and number of perforations will equate with the breach number; Notch geometry on the last sign indicating number circle (9) is that a support parallactic angle (33), another side arc transition are arranged on one side; The notch geometry of following code wheel (21) is that both sides all are arc transition; The head of the spacer (8) of last sign indicating number circle (9) is pointed, the head of the spacer (46) of following code wheel (21) is circular, therefore, last sign indicating number circle (9) can only rotate toward counter-clockwise direction, following code wheel (21) then can arbitrarily rotate, and pointer (27) is fixed on core wheel (38) end and exposes outside the shell (26), and digit plate (28,17) is fixed on correspondence position, wherein numeral is protruded, and is convenient to use at night or blind person and uses.

When using the utility model, finish password earlier, during coding, open shell (26), again reed is taken turns (6), last sign indicating number circle (9), breach wheel (11) is taken out, clockwise rotate (people sees indoor) breach wheel (23) then, because Xiao's (22) effect, following code wheel (21) is also along with rotation, make the big breach (36) on the breach wheel (23) aim at even door bolt (5), at this moment second sign indicating number (units) that seeing a yard board (28) go up the corresponding numeral of pointer (27) on the casing cover is password mixes up second digital back first number of accent, when transferring sign indicating number, breach is taken turns (11) to be put, Xiao (24) upwards exposes, last sign indicating number circle (9) is aimed at Xiao Zi (24) to be folded, reed being taken turns (6) alignment keys Xiao (47) loads onto again, inhour (people sees indoor) is rotated, make the reed (7) on the reed wheel (6) push up the interior double wedge (39) that sign indicating number encloses (9), rotate the big breach (36) that makes breach wheel (11) again and aim at even door bolt, seeing on the casing cover that the numeral on pointer (27) the indication digit plate (28) is first number of password (being units).

When unblanking, key (18) is inserted lock core (19), inhour (people sees outdoor) is rotated, make pointer (27) aim at first number of password on the digit plate, that changes clockwise aims at pointer 0 scale again, rotates clockwise then again, makes pointer aim at second number that digit plate (28) is gone up password, at this moment the big breach (36) of breach wheel (11,23) companys of aligning door bolt (5) gets final product a lock and opens as long as rotate outer bracelet (16).After lock was opened, key should break away from the breach of Lian Baoxin (13) and the swinging plate (20) of lock core (19), and key is aimed at 0 scale again, just can take out key.Owner places the position that breaks away from swinging plate (20) all the time at the indoor Lian Baoxin (13) that allows, and the switch door is as long as rotate handwheel (25).When owner goes out to lock a door, put into Lian Baoxin (13), swinging plate (20) is inserted in the breach of Lian Baoxin (13), will insert key simultaneously and dial random password.

The utility model has the advantage of safe and reliablely, unblanking to have key, knows password, Indispensable.
