Abstract

The utility model discloses an adjustable cipher lock, which is composed of a coding mechanism and an operating mechanism, wherein, the coding mechanism is composed of an opening disc 3, a fluted disc 5, a positioning shaft 6, a lettered disc 7, a torsion-operating disc 8, a limited spring 10 and a reset spring 11, and the operating mechanism is composed of a lock blade (2), a slide block (4) and a lock tongue lever 13. The utility model can adjust the cipher, has the advantages of strong confidentiality and anti-decoding function, can be matched with the existing built-in door lock, and can also be used for safes and anti-theft mechanisms.

Description

Adjustable permutation lock

The utility model relates to lockset, and particularly a kind of adjustable cipher with pellet shot from a slingshot hidden door lock adapted is locked.

The confidentiality of the coded lock that has in the prior art is not good, can untie password by feel the bump sound that produces between the opening tool with hand or ear, and the password of many coded locks is non-adjustable; In addition, unique way that existing hidden door lock is encrypted is exactly more to change former lock and add special coded lock.

The purpose of this utility model is to provide a kind of confidentiality fine, and password is adjustable, can lock with the adjustable cipher of cylinder lock door lock adapted.

Above-mentioned purpose of the present utility model is to realize by such technical scheme: promptly it is by lid, end lid, coding mechanism and executing agency form, it is characterized in that coding mechanism is by opening disk, fluted disc, locating shaft, lettered dial, turn-knob dish, limit spring, back-moving spring are formed, wherein fluted disc is fastened on the lettered dial, and the groove of the identical five equilibrium on the evenly divided on the lettered dial and the fluted disc end face is corresponding; The opening disk radial direction has a groove mouth, and riveting have one downwards can with the protruding key of the five equilibrium groove clutch of fluted disc end face, opening disk and back-moving spring are engaged in by locating shaft in the hole of fluted disc, and limit spring heads on the teeth groove of fluted disc in the other direction, to prevent the backwards rotation of lettered dial; Executing agency is made up of locking plate, slide block, the dead bolt lever that is connected with pellet shot from a slingshot hidden door lock dead bolt, wherein on the slide block slide opening is arranged, the locating shaft of coding mechanism is positioned at wherein, have on the slide block can with the protruding key of the groove clutch of opening disk, the locking plate of slide block top for supporting by the locating shaft inverted draw cut, locking plate has oblique sliding surface, and its button is exposed at outside the lid.

Said structure of the present utility model can provide a non-limiting embodiment by accompanying drawing and further specify.

The following accompanying drawing of the utility model embodiment:

Accompanying drawing 1 is the main schematic diagram that cuts open;

Accompanying drawing 2 is a vertical view;

Accompanying drawing 3 is that the A-A of Fig. 1 is to sectional view;

Accompanying drawing 4 is that the B-B of Fig. 3 is to sectional view;

Accompanying drawing 5 is that the K of Fig. 1 is to partial schematic diagram.

With reference to accompanying drawing: this adjustable cipher lock is by lid 1; Locking plate 2; Opening disk 3; Slide block 4; Fluted disc 5; Locating shaft 6; Lettered dial 7; Turn-knob dish 8; Box plate 9; Limit spring 10; Back-moving spring 11; Door face board 12; Door lock tongue lever 13 major parts such as grade are formed.

Opening disk 3, fluted disc 5, locating shaft 6, lettered dial 7, turn-knob dish 8, limit spring 10; Back-moving spring 11 is formed single encoded mechanism.Connect and drive connection is: fluted disc is fastened on the lettered dial, and the front of lettered dial has on 12 five equilibriums numbers and the fluted disc end face has 12 five equilibrium grooves corresponding.The opening disk radial direction has a groove mouth, with groove at an angle of 90 riveting a protruding key is arranged.Opening disk and back-moving spring are engaged in by locating shaft in the hole of fluted disc, the protruding bond energy of opening disk and the teeth groove clutch of fluted disc, and protruding key combines with teeth groove when being subjected to the pressure of locating shaft, and rotate positive lettered dial this moment, and opening disk is rotated synchronously; Eliminate when pressure, opening disk is in a disengaged position, and is in static.At this moment the adjustable encoding function of single type drum has just been realized from new combination in sign indicating number position that can the hand-over word code-disc, and limit spring 10 heads on the teeth groove of fluted disc in the other direction, can prevent the lettered dial backwards rotation, forward rotates can produce sensation and the sound that replaces.Lettered dial is to be fixed on by the turn-knob dish to need to install on the door face board of this lock.

Locking plate 2; Slide block 4; Door lock tongue lever 13 is formed executing agency, is with the connector of three addressable parts and three chain codings of code-disc of pellet shot from a slingshot hidden door lock formation, makes three code-discs and opening disk produce the driving member that clutch action reaches synchronous rotation.Drive connection is: the dead bolt of door lock tongue lever and pellet shot from a slingshot hidden door lock fuses, and when rotational lock core, the upper and lower motion of door lock tongue lever energy promotes slide block left and right moving in lid.Riveting has three protruding keys on the slide block, when slide block drive locking plate is moved to the left, by the thrust that produces on the oblique sliding surface of locking plate, can make opening disk and lettered dial be in bonding state, rotate lettered dial again, just the notch of three opening disk can be forwarded on the straight line, align the position of three protruding keys on the slide block, just the set right position of institute's encryption, at this moment then can lock the door lock lever three protruding keys on the slide block are withdrawed from outside the groove of opening disk, dial the mess code dish then, the enable possition that the notch of opening disk staggers the protruding key of slide block, the door lock lever is stuck, realized the function of coding mechanism control pin tumbler lock, when opening door lock, earlier with password to good, slide block could just can be opened by mobile door lock, when needing recompile, press part locking plate 2 and be exposed at the outer button of lid opening disk is combined with lettered dial, turn to disengagement again behind the open-circuit position of three notches, again organize into groups three character code aligned position, just can be by door lock on the newly organized coded lock.

The utility model is owing to adopted its extremely long-pending effect of said structure to produce as follows:

One) comprise three coding mechanisms in the above-described embodiments, the code-disc of each coding mechanism has 12 five equilibrium numbers, has 12 ³Select for use when individual number is available for users to encode, the user can change password by the digital arbitrary combination that provides, and can not be subjected to the restriction of manufacturing firm or other factors, has cocksure confidentiality.

Two) owing between the opening tool of code-disc and inside clutch is arranged, transfer random password again when locking after, just can not attempt to rotate code-disc, remove to feel the bump that produces between the opening tool with hand, untie password.

Three) adjust encoding operation conveniently, only need press the locking plate button that is exposed at outside the lid and get final product.

The utility model can also connect and compose connection with electronic warning and steal warning adjustable cipher lock.
