Description

Coaxial machinery cipher lock

The utility model belongs to lockset, in particular for the coaxial mechanical code lock of aspects such as door, furniture, safety cabinet.

Though present various mechanical code lock has his own strong points, result of use is also not very good.As Chinese patent CN85200207 number disclosed mechanical code lock,, can open the chance of lock and have after all but only rotate number, and the combination number of times of its password is also few though have the key of need not, need not to join in addition characteristics such as handle; As Chinese patent CN86101669 number a kind of universal safety cylinder locks of mechanical cipher type is also disclosed in the recent period, though have characteristics such as simple in structure, that cost is low, also exist the password combination number of times few, and the safety relative mistake some wait not enough.

The utility model improves at the deficiency that prior art exists, provide a kind of compact conformation, good looking appearance, easy to use, must be that key and figure disc use simultaneously, the coaxial mechanical code lock of high safety.

The utility model is achieved by following manner: a kind of coaxial mechanical code lock, partly constitute by lock body part and lock core, lock body part comprise the lock body shell and on oblique tongue, spring in the oblique tongue rod portion and handle, side's tongue and location-plate and jam plate and junction plate and spring, inner lock head and pull out sheet, lock core partly comprises lock core and turns round sheet, the figure disc of lock core shell and last band scale thereof, the slide plate of lock core front end and on ratchet and ratchet pawl etc., feature of the present utility model is: the figure disc of lock core part is designed to the interior figure disc of three layer construction, middle figure disc, the nickname code-disc, its front end be provided with its one to one in the tone mark dish, middle tone mark dish, the investigation mission outside the city or town dialer, their contact position is shaped on the number tooth that cooperatively interacts respectively, and in above-mentioned, in, nickname code-disc and tone mark dish are coaxial radially to be sleeved on the lock core shell, wherein lock core and interior figure disc are provided with five lock pin aperture, lock core latch and figure disc latch and dog chart are housed respectively in it, interior tone mark dish is shaped on the coil component spring groove near the lock core place, tone mark spring and back-up ring are housed in it and withstand interior tone mark dish, in making, in, number tooth on the investigation mission outside the city or town dialer and corresponding in, in, number tooth on the nickname code-disc is in mated condition, and in, in, be shaped on the through hole that is used for tone mark on the investigation mission outside the city or town dialer, the former is a screwed hole, both are unthreaded hole and the aperture screwed hole greater than the former for the back, simultaneously, in, in, all being shaped on the identical circle of size on the end disc of investigation mission outside the city or town dialer lacks, a tone mark bar also is set separately in addition, and its front end is shaped on screw thread and cooperates with screwed hole on the interior tone mark dish.Be shaped on the same direction of location-plate, jam plate and the lock body shell of shank part with middle tone mark dish and investigation mission outside the city or town dialer on the through hole that through-hole aperture is identical and the direction position is also identical, like this tone mark bar can directly insert on location-plate, jam plate and the lock body shell through hole with in, through hole and contact on the investigation mission outside the city or town dialer with screwed hole on the interior tone mark dish, pull out after screwing on interior, in, the investigation mission outside the city or town dialer make they the number tooth and interior, in, the number tooth on the nickname code-disc breaks away from, and can regulate the conversion number like this.

Its work and use are: when unblanking key is inserted in the keyhole of lock core, the outer face of lock core latch overlaps with the cylindrical line of lock core, interior figure disc can rotate on lock core, this moment key, because the ratchet pawl on the lock core slide plate is to the stopping function of ratchet, lock core can't be driven turn round the sheet rotation, this explanation only can't be opened lockset with key.Have only check mark code-disc and tone mark dish to carry out tone mark, promptly transfer nickname code-disc, middle figure disc, interior figure disc successively, make them to the fixed original number of setting up in advance of unblanking, in this moment, in, the circle on the investigation mission outside the city or town dialer lacks alignment just and contacts simultaneously on the catch of lock core slide plate below, under the tension of skateboard spring, slide plate upwards slides and makes ratchet pawl break away from ratchet, and at this moment key can make lock core drive to turn round the sheet rotation lockset is opened.If without key and since the effect of figure disc latch make in figure disc can't rotate and square with sign indicating number, lockset also can't be opened like this, can be threaded to the number of unblanking on other number preventing after lockset is opened in addition and give away secrets.When closing lockset, because the unidirectional stopping function when the ratchet stop system is only unblanked, so can't prevent lock core to shutting the direction rotation, as long as figure disc and drive lock core and turn round sheet and can shut lockset in rotating, the disk that lockset is locked on the tone mark dish of back pushes up slide plate downwards, make ratchet pawl block ratchet, lock core can't be rotated reach the purpose that shuts.When number is unblanked in the needs levelling, must original number on and lockset carry out after all opening, the through hole that is used for tone mark this moment on each component aligns fully and becomes a through hole, like this tone mark bar is inserted in the through hole be used for tone mark and screw with screwed hole on the investigation mission outside the city or town dialer, in pulling tone mark bar makes, in, number tooth on the investigation mission outside the city or town dialer with in, in, number tooth on the nickname code-disc breaks away from, at this moment insert key and can rotate successively in, in, the nickname code-disc, adjust to the needed number of unblanking, after mixing up the tone mark bar is pushed inward, in making, in, number tooth on the nickname code-disc with in, in, the engagement of number tooth on the investigation mission outside the city or town dialer, and screw off the tone mark bar and finish whole tone mark process.

The utility model is compared with prior art, has characteristics such as compact conformation, good looking appearance, easy to use, high safety.
