Description

The coded lock of gear type crypto control unit dialing

The utility model relates to a kind of coded lock, exactly is to have the coded lock that the gear type crypto control unit is opened with dial mode.

The lockset product has the key of use and accesses to your password two kinds by the opening ways classification.The lockset product that accesses to your password has mechanical code lock and electronic type coded lock two classes.The defective that traditional mechanical cipher is latched in is, the password figure place is low, be generally about three figure places, repetition rate of coding height, poor stability, the open operation knob that accesses to your password, about the calibrated scale that circles round, unglazed photograph can not be operated, it is very inconvenient to use.Advantages such as since the extensive use, the electronic type coded lock is with its password figure place height in the lockset product for electronic technology, and the repetition rate of coding is low, and good confidentiality is safe and reliable, and open operation is convenient have obtained widespread usage.But the dependability of electronic type coded lock is subjected to the restriction of electronic component and control power supply.

The purpose of this utility model is: provide a kind of dialing formula operation, password figure place height, the repetition rate of coding low, open and have the coded lock that the gear type crypto control unit is opened with dial mode easily.

The technical solution that realizes its purpose is such:

Have dialing and open the coded lock of gear type crypto control unit, comprise lock body, dialing transmission mechanism, it is characterized in that: the dialing transmission mechanism is made up of dial 2, guide gear 17, password gear pair, handle stopping wheel 14 etc.; Handle 1, dial 2, guide gear 17, driving gear 15 and handle stopping wheel 14 are located in the handle rotating shaft 13 successively, and the handle rotating shaft is located on the lock body; Described dial 2 is provided with 13 finger holes, and described guide gear 17 and driving gear 15 corresponding sides are respectively equipped with the helical teeth cover of engageable transmission, and the radially excircle of described handle stopping wheel 14 is provided with the stop breach; Be located on the lock body by axle 4 with the password gear 8 of driving gear 5 engagement, a side of password gear 8 is provided with the unblank jacking block corresponding with handle stopping wheel 14, and the side of password gear 8 opposite sides is provided with the cipher ring 9 that equates with password figure place quantity more than 4; Bar shaped guide strip 3 is located on the lock body by axle 18, and the one end contacts with guide gear 17, and the one side is that clutch shifting block 16 contacts with driving gear 15, the stop thimble 5 corresponding with cipher ring 9 that bar shaped guide strip 3 other ends are provided with interlock.

The utility model has overcome the defective that traditional mechanical cipher is latched in, and can carry out any group code of 7～10 figure place passwords, the repetition rate of coding to the password of 7 figure places be 1,000,000/, the password of 8 figure places is 1/10000000th, is 1/100000000th to the password of 9 figure places.It is reasonable in design, simple in structure, adopt the operation of dialing formula, it is convenient, safe and reliable to open, need not illumination and control power supply, advantage such as strong security, the repetition rate of coding of firm, wear-resisting durable, reliable operation of the parts that integrate mechanical lockset and electronic type lockset is low, unlatching is convenient.

Embodiment:

This coded lock comprises lock body, dialing transmission mechanism etc.The dialing transmission mechanism is made up of dial 2, guide gear 17, password gear pair, handle stopping wheel 14 etc.Handle 1, dial 2, guide gear 17, driving gear 15 and handle stopping wheel 14 are installed in the handle rotating shaft 13 successively, and the handle rotating shaft is loaded on the lock body.Have 13 finger holes on the described dial 2, described guide gear 17 is equipped with the helical teeth cover of engageable transmission respectively with driving gear 15 corresponding sides, has the stop breach on the radially excircle of described handle stopping wheel 14; Be installed on the lock body by axle 4 with the password gear 8 of driving gear 5 engagement, a side of password gear 8 is equipped with the unblank jacking block corresponding with

handle stopping wheel

14, and 4 cipher rings 9 with password figure place equal amount are housed on the side of password gear 8 opposite sides; Bar shaped guide strip 3 is installed on the lock body by axle 18, and the one end contacts with guide gear 17, and the one side is that clutch shifting block 16 contacts with driving gear 15, the stop thimble 5 corresponding with cipher ring 9 that bar shaped guide strip 3 other ends are equipped with interlock.

Its operating principle is as follows:

Clockwise rotate with finger actuation dial 2, clockwise turn to dialing status, guide gear 17 clockwise rotates synchronously, drive guide strip 3 deflection in the same way,

guide strip

3 and 16 interlocks of clutch shifting block, make clutch shifting block 16 oblique cuttings enter driving gear 15 outer faces, make the helical teeth cover and dial 2 axle sleeve end face helical teeth engagement interlock of driving gear 15 1 side end faces, making driving gear 15 drive password gear 8 rotates, pushed on the dialer behind the final position when dial 2 is clockwise, promptly beginning return reverses, guide gear 17 interlocks reverse, make guide strip 3 reverse deflections, guide strip 3 and clutch shifting block 16 interlock returns, driving gear 15 and guide gear 17 end face helical teeth covers are taken advantage of a situation to be backed down by spring action and are separated.This moment, stop thimble 5 acted on cipher ring 9 when password gear 8 forwards stop thimble 5 places to, and Fig. 5 is seen in the revolution of stop password gear 8 and driving gear 15.If stop thimble 5 fails to act on cipher ring 9, see Fig. 6, Fig. 7, be that stop thimble 5 is thrown off with cipher ring 9, the effect of return spring 7 is to be repositioned to original state, during password gear 8 returns the effect of damping cover 6 be to make password gear 8 and driving gear 15 with gently at the uniform velocity state reach initial position.

And the like by number stirring dial 2, driving gear 15 and password gear 8 are rotated synchronously, when last password number group intact, when cipher ring 9 arrives final stop position, the jacking block 11 of unblanking withstands unlock lever 10 and moves in the same way, and unlock lever 10 drives handle scotchs 12, and handle scotch 12 1 ends block the stop breach that handle stopping wheel 14 footpaths make progress and are opened, at this moment, rotating handle 1 opens lockset.

On password gear 8 by the corresponding process of cipher ring 9 of settling of the password of any setting be, when dialing clockwise, the corresponding driving gear of dial turn angle displacement rotates the number of teeth, and the big corresponding number of teeth of rotating of dialing stroke is many, and the dialing stroke is little, and the corresponding number of teeth of rotating is few.Be set with the rotation displacement of three spacings (being the finger hole of nil) on the dial, its effect is that guide gear 17 meshes the rotational travel displacement that needs with driving gear 15.Settle the basic skills of cipher ring 9 to be exactly on password gear 8, by each password number of teeth that displacement is rotated when dialling separately, the final position is exactly with the addition successively of the corresponding displacement number of teeth of each password figure.As establish number of teeth of " 0 " displacement, two numbers of teeth of " 9 " displacement, three numbers of teeth of " 8 " displacement, by that analogy, ten numbers of teeth of " 1 " displacement so just can calculate that successively correspondence position on cipher wheel 8 determines the position of cipher ring 9 by each password figure displacement number of teeth.
