CN2306293Y - mechanism for opening lock by using cipher skeleton key - Google Patents

Abstract

The utility model relates to an unlocking mechanism of a cipher skeleton key, which is composed of a key seat, a coding key needle, a lock seat, a movable core, a fixing core, a coding cylinder, a locking cylinder, a spring, an unlocking arm, and a back cover. The utility model combines the functions of direct unlocking and a cipher, and the cipher can be independently adjusted by a user. The mechanism has the advantages of simple structure, easy fabrication, convenient operation, and good security performance, can be fabricated to series products, and is suitable for padlocks, vehicle locks, drawer locks, safety door locks, strong box locks, security cabinet locks, etc. One key can unlock all locks with different types and different specifications of the same series through adjusting different secret codes, and the versatility is strong. The coding key needle can codes more than 3600000 different codings; the utility model is particularly suitable for occasions having high requirement to security.

Description

A kind of universal password key unlocking mechanism

The utility model is a kind of mechanical unlocking mechanism.

At present the lock that uses has two classes usually, and a class is an electronic lock, and second class is a mechanical lock, mechanical lock have again use key head straight for lock and without two kinds of the coded locks of key.Their shortcoming is: electronic lock technical requirements height, and price comparison is expensive, and needs power supply, and the scope of application is restricted.Use at present the mechanical lock of key to be subjected to structure influence, confidentiality is relatively poor, and the coded lock password is fixed during generally by manufacturer production, and oneself can not be adjusted, and is cumbersome during use.

The purpose of this utility model is to avoid above-mentioned weak point and a kind of improved mechanical unlocking mechanism is provided.

Below in conjunction with accompanying drawing technical solution of the present utility model is specifically described as follows:

The utility model unlocking mechanism, comprise key 1, lock 2, moving core 3, decide core 4, the arm 5 of unblanking, bonnet 6, coding spoon pin 7, spoon lid 8 are housed in key holder, coding pellet shot from a slingshot 9 are housed, decide in-core locking pellet shot from a slingshot 10, spring 11, spiral cover 12 are housed at the moving in-core of locking.

Across is drilled with 10 holes on the key holder cross section, and coding spoon pin is interspersed in the hole, and the spoon lid is positioned at coding spoon pin back; Moving core is housed in the lock, decides core and be fixed on the bonnet; Moving core with decide the driving fit of in-core side, at moving core, decide that corresponding across with key holder is drilled with 10 holes on the core cross section, the pellet shot from a slingshot of encoding is housed in the hole, locks pellet shot from a slingshot, spring, decide the core rear portion spiral cover be housed.

Advantage of the present utility model is to have taken into account simultaneously and heads straight for and cryptographic function, and the user can adjust password voluntarily.This mechanism structure is simple, manufacturing, easy to use, and security performance is good, can be made into series of products, is applicable to padlock, lock, drawer-lock, insurance lock, Safe lock, safety cabinet lock etc.A key can be opened the lock of all homologous series different models, different size, highly versatile by adjusting different passwords.Coding spoon pin can be compiled out more than 3,600,000 coding inequality, is specially adapted to the demanding occasion of confidentiality.

The drawing of accompanying drawing is described as follows:

In the accompanying drawings, marking each numeral is expressed as follows respectively;

1. key holder, 2. lock, 3. moving core 4. decide core, 5. drives the arm lock, 6. bonnet, a 7. coding spoon pin, 8. spoon lid, 9. the coding pellet shot from a slingshot 10. locks pellet shot from a slingshot, 11. springs, 12. spiral covers.

Embodiment:

Key holder cross section nine bore dias are 1 millimeter, and coding spoon pin is that 1 millimeter of diameter is cylindrical, and afterbody is wide 2 millimeters, long 3 millimeters, thick 1 millimeter square column type, in its wide upper punch coding is arranged 0-9 number; The anterior aperture of moving core is that 1 milli comes, and it is 2 millimeters that the rear portion reaches the aperture of deciding core, and coding pellet shot from a slingshot, locking billiards diameter are 2 millimeters.

Key holder, the available copper material of spoon lid, a spoon pin can use steel, and lock, the arm of unblanking, bonnet can use iron material, moving core, decide core, the pellet shot from a slingshot of encoding, lock pellet shot from a slingshot, spring, spiral cover and can make with copper material.

According to the password of oneself determining, each coding spoon pin is inserted in the respective aperture of key holder, screw bonnet.Open the lock core bonnet, in lockhole, put into and spoon pin corresponding codes pellet shot from a slingshot, put into locking pellet shot from a slingshot and spring again, screw spiral cover.The coding spoon pin of key is inserted in the corresponding lockhole, screw key, the moving equidirectional rotation of core drives the arm of unblanking that is enclosed within on the moving core and rotates, and drives dead bolt by interlinked mechanism and plays the expense effect.

Claims (2)

1, a kind of universal password key unlocking mechanism, comprise key holder 1, lock 2, moving core 3, decide core 4, the arm 5 of unblanking, bonnet 6, it is characterized in that: coding spoon pin 7, spoon lid 8 are housed in the key holder, and moving in-core is equipped with coding pellet shot from a slingshot 9, decides in-core locking pellet shot from a slingshot 10, spring 11, spiral cover 12 are housed.

2, mechanism according to claim 1 is characterized in that: across is drilled with 10 holes on the key holder cross section, and coding spoon pin is interspersed in the hole, and the spoon lid is positioned at coding spoon pin back; Moving core is housed in the lock, decides core and be fixed on the bonnet; Moving core with decide the driving fit of in-core side, at moving core, decide core corresponding across with key holder on cross section and be drilled with 10 holes, the pellet shot from a slingshot of encoding is housed in the hole, locks pellet shot from a slingshot, spring, decide the core rear portion spiral cover be housed.
