Изобретение относитс к запирающим устройствам, в частности к кодовому механизму , который может быть использован в различных замках.The invention relates to locking devices, in particular to a code mechanism that can be used in various locks.

Известен кодовый механизм замка, содержащий цилиндрический корпус, в основании которого установлены поворотные оси с кодовыми дисками, каждый из которых имеет на периферии выступ, и стакан, имеющий в основании вырезы, выполненные в соответствии с выступами кодовых дисков Ш .Known code mechanism of the castle, containing a cylindrical body, the base of which is equipped with rotary axes with code disks, each of which has a protrusion on the periphery, and a glass, having cut-outs at the base, made in accordance with the protrusions of the code disks Ш.

Недостатком его вл етс мала надежность запирани , что объ сн етс несовершенством исполнени корпуса и стакана.The disadvantage of it is the low reliability of locking, which is explained by the imperfection of the design of the body and glass.

Целью насто щего изобретени вл етс повыщение надежности запирани .The purpose of the present invention is to increase the reliability of locking.

Указанна цель достигаетс тем, что корпус и стакан имеют кольцевые выточки, в которых расположены кодовые диски.This goal is achieved by the fact that the body and the glass have annular recesses in which the code disks are located.

На фиг. 1 изображен механизм со стороны поворотных осей; на фиг. 2 - разрез А-А фиг. 1; на фиг. 3 - разрез Б-Б фиг. 2.FIG. 1 shows the mechanism on the side of the pivot axles; in fig. 2 - section A-A of FIG. one; in fig. 3 - section bb FIG. 2

Кодовый механизм содержит цилиндрический корпус 1, в основании которого установлены поворотные оси 2 с кодовыми дисками 3, каждый из которых имеет на периферии выступ 4. В корпусе расположен стакан 5, имеющий в основании 6 сквозные вырезы 7, выполненные в соответствии с выступами 4 кодовых дисков 3. Корпус 1 и стакан 5 имеют кольцевые выточки 8 и 9 соответственно, в которых расположены кодовые диски 3.The code mechanism contains a cylindrical body 1, in the base of which rotary axles 2 with code disks 3 are installed, each of which has a protrusion 4 on the periphery. In the case there is a cup 5 having 6 through-cut 7 at the base, made in accordance with the protrusions 4 code disks 3. Case 1 and glass 5 have annular undercuts 8 and 9, respectively, in which the code disks 3 are located.

Стакан в корпусе установлен с возможностью продольного осевого перемещени и имеет на конце диаметрально-расположенные отверсти 10 под запирающий стержень 11, позвол ющий использовать запирающий механизм в вис чем замке, замыкающим дверные ушки 12.The glass in the housing is installed with the possibility of longitudinal axial movement and has diametrically located holes 10 at the end for the locking rod 11, which allows the use of a locking mechanism in the door than the lock closing the door ears 12.

Кажда поворотна ось 2 имеет на торцовой поверхности шлиц 13 дл ключа (не показанного на чертежах) и риску, а на поверхности основани корпуса 1 изображена цифрова индексаци , расположенна по кругу каждой поворотной оси.Each pivot axis 2 has a slot 13 on the end surface for a key (not shown in the drawings) and a risk, and on the surface of the base of the housing 1 is a digital index located in a circle of each pivot axis.

Механизм работает следующим образом.The mechanism works as follows.

Claims

For locking the lock, glass 5 is installed so that the door lugs 12 are in the inner cavity of the glass, and their holes coincide with diametrically located holes 10 of the glass. Then, a locking rod 11 is inserted into these holes and each axis 2 is rotated until the risks coincide with the corresponding risk of digital indexing applied to the surface of the base of case 1. For example, if the lock has code 7, 8, 5, 2, then the first rotary axis is set to its risks coincide with the risk under index 7, the second under index 8, and so on. The pivot axes 2 installed by the digital indexing code ensure that the discs 3 are in position when their projections 4 coincide in position with the through notches 7 of the base 6 of the cup 5. In that In this position of the disks, the cylindrical body 1 freely slides onto the glass 5 until the base of the latter is pressed against the base of the cylindrical body. The code discs 4 are located in annular recesses 8 and 9, made in housing 1 and respectively glass 9. The process of locking is completed by randomly turning each of the rotary axes 2 clockwise or counterclockwise and randomly rotating body 1 relative to glass 5. To unlock the lock These operations are performed in reverse order, but this cannot be done without knowledge of the code. Claim lock mechanism, comprising a cylindrical body, at the base of which are mounted rotary axes with code discs, each of which has a protrusion on the periphery, and a cup, having cut-outs at the base, made in accordance with the protrusions of the code discs, characterized in that In order to increase the reliability of locking, the housing and the cup have annular recesses in which the code disks are located.
