Description

Cipher hang lock

Technical field:

The present invention relates to a kind of cipher hang lock, especially relate to a kind of Mechanical ring latch of convertible password, belong to lock technology field.

Background technology:

Chang Yong padlock is divided into two classes substantially in the market: a class is to use key operated; The another kind of password that is to use is opened.This two classes lockset all has pluses and minuses separately in use, wherein: and comparatively simple with the key lock unlatching, but the problem that exists is that key is lost easily, and safety is not high; Though open the problem that does not have key loss with password, but because the coded lock major part is used for locking than wisp, therefore its scope of application is narrower, and small part can be used for locking the password of can not changing of larger object, careless leakage owing to password descends the security performance of lock like this, and the lock that can change password that has, its structure is password board and cipher wheel branch to be come install after making again, when the change password, reinstall to other positions of cipher wheel after the password board taken off from cipher wheel again, the password board damages after repeatedly taking off conversion easily like this, also loses easily.

Summary of the invention:

The objective of the invention is to provide a kind of applied widely, security performance is high, simple in structure, convenient for installation and maintenance, cipher hang lock that password can be adjusted variation arbitrarily.

The objective of the invention is to reach like this, a kind of cipher hang lock, it mainly is made up of U-shape sword iron, lock body, number dial assembly and dial supporter assembly and capping, and the end, two ends of described U-shape sword iron is formed with a plurality of latch hooks respectively, and structure is a groove between latch hook; The end, two ends of described lock body is expanded respectively and is provided with the dial seat, be formed with the dial chamber in the dial seat, offer the number form respectively in the outside of dial seat, the number form communicates with the dial chamber, inboard, two ends at lock body offers the alignment pin chamber respectively, and the alignment pin chamber communicates with the dial chamber; Described number dial assembly has two groups at least, be placed in the dial chamber, every sets of numbers dial assembly is by dial, number adjustment dish, a pair of moving tooth is formed, between the external surface of dial, be provided with number, offer draw-in groove between adjacent number, be formed with number adjustment dish chamber in the centre of dial, between on the sidewall in number adjustment dish chamber, be furnished with the moving tooth caulking groove, be formed with through hole in the middle of the bottom, number adjustment dish is placed in the number adjustment dish chamber, centre at number adjustment dish offers first lockhole, the one side expansion of first lockhole is provided with first keyhole slots, on the outer wall of number adjustment dish, be formed with a pair of moving tooth groove, a pair of moving tooth respectively with moving tooth groove and dial on corresponding moving tooth caulking groove chimeric; Described dial supporter assembly has two groups at least, be placed in the alignment pin chamber, every group of dial supporter assembly is made up of spring, alignment pin, and an end of alignment pin cooperates with an end of spring, the other end cooperates with corresponding draw-in groove on the dial, and the other end of spring cooperates with the alignment pin chamber; Described capping is positioned at the dial chamber on number dial assembly top, and fixes with the dial seat, offers second lockhole in the middle of it, and the side expansion of second lockhole is provided with second keyhole slots.

Second lockhole, second keyhole slots of capping of the present invention centre are all identical with first lockhole, the shape of first keyhole slots, the size of number adjustment dish centre.

The aperture of through hole of the present invention is greater than the aperture of first, second lockhole.

The width of the groove between latch hook of the present invention is greater than the thickness of number adjustment dish.

The group number of number dial assembly of the present invention and dial supporter assembly is identical, the position is corresponding.

The position of a pair of moving tooth groove of the present invention on number adjustment dish outer wall is provided with axisymmetricly.

The present invention is formed with the spring base that is used for mounting spring in the wall inboard, chamber in described alignment pin chamber.

Capping of the present invention achieves a fixed connection by steady pin and dial seat.

The present invention adopts one of advantage that has behind the said structure, passes through a pair of moving tooth, can adjust the installation site of number adjustment dish in dial, thereby can change password quickly and easily, effectively improves the safety of lock; Two, number is directly arranged in the external surface of dial, thereby overcome the drawback that the password board damages and loses easily easily in the prior art; Three, simple in structure, be convenient to install, safeguard and use; Four, can not only lock wisp and can lock big object, applied widely, can be widely used on various types of vehicles such as bicycle, electric motor car, the motorcycle, also can be applicable on all kinds of door, the window.
