Abstract

Usage: in the construction of various locks. SUMMARY OF THE INVENTION: The locking mechanism of the lock includes a housing. A rotary cylindrical core with longitudinal grooves and an annular groove is placed in the case. In the hollows of the heart: 2nd & t, the pins are spring-loaded in the axial direction with the possibility of longitudinal movement of the pins with working and false grooves. The locking elements are housed in the body and the annular groove of the core with the possibility of being placed in the grooves of the pins. The locking pins are controlled by a push key. The pins are made flat and are installed with the possibility of radial movement by means of flat springs placed in the recesses of the separator. In the axial direction, the pins are spring-loaded by means of one helical spring. 7 silt

Description

The invention relates to locking devices, in particular, to a cylinder mechanism that can be used in the construction of various locks.

The purpose of the invention is to increase the reliability of the lock in operation.

The goal is achieved by the fact that in the mechanism the flat-shaped coding pins are placed with the possibility of movement in the axial direction in jointly made grooves of a cylindrical core and an intermediate flange consisting of two symmetrical parts (sectors) fixed between two detachable parts of the body and partially placed in an annular a groove made in the body of a cylindrical core, whose rotation is possible only when all flat pins are installed with their secret recesses against the end of the body the flange, which is carried out with a push-type key, it is possible to rotate the core in the housing together with the pins in any direction an unlimited number of times, and when the key is removed from the key channels, all the pins return to their original position with one spring common to them, while spontaneously moving the pins in the slots are permanently pressed by flat springs

Fig 1 shows the locking mechanism of the lock, side view, section; in Fig 2 - section A-A in Fig 1 (mechanism in the locked position): in Fig 3 - the same, but in the open position; Fig 4 is a view B in Fig 1; in fig. 5 is a view of B in FIG. 1, in FIG. 6 a flat-shaped pin; Fig 7 - push key

The cylinder lock mechanism contains a split housing consisting of a front 1 and a rear 2 between which in a groove in the front of the case there is a flange 3 consisting of two symmetrical parts that contain locking lugs 4 placed in the corresponding diametrical grooves of the case. The parts of the body are connected by screws 5, in which the cyindric core 6 containing an annular groove 7 is placed with the possibility of rotation, in which the flange 3 containing joint elements is placed with its internal annular parts.

The recesses 8 and 9, respectively, are made both in the core and in the french, respectively, into which the flat pins 10 are spring-loaded, axially spring-loaded by the spring 11, and in the radial direction by the spring 12. The flat pins contain recesses 13, the possibility of which is indicated center lines 14, as well as on their surface, contain false notches 15. A push-type key 16 can be made, for example, of sheet metal by milling or by stamping its secret protrusions 17 and holes into which after giving the key a cylindrical shape, a ring 18 is placed. Attach the mechanism to the locking element with screws screwed into the threaded holes 19. To orient the insertion of the key 16 into the key channels 20, a mark 21 is applied to the front part of the housing. The corresponding mark is also applied to the key (not shown).

The locking mechanism of the lock works as follows.

To unlock (lock) the key lock mechanism 16, the code lugs 17 are oriented relative to the key channels 20 so that the key on the key (not shown) and the mark 21 on the front side of the lock match, and the key is then pressed all the way into the cylindrical core 6. Code lugs 17 of the key 16, interacting with the pins 10, having overpowered the spring 11, move the pins 10 in the slots 8 and 9 to a position in which the notches 13 of all the pins 10 are located along the same annular line against the flange 3. its part located in the bore 7 of the core 6, what

allows the free rotation of the core together with the pins both clockwise and counterclockwise an unlimited number of times. FIG. 2 shows the mechanism in the locked position, and FIG. 3 when unlocking (locking) when the core 6 is rotated together with the pins 10. When removing the key 16c of the key channels 20, the core 6 must be oriented so that the grooves 8 of the core 6 are aligned with the slots 9 of the flange 3 (Fig. 2), while under the action of the spring 11 the pins 10 move to their original position and block the core from turning relative to the body (flange 3), the key will be pushed out of the key channels.

Claims (1)

Claims The locking mechanism of the lock, comprising a housing, a rotatable cylindrical core with longitudinal grooves and an annular groove placed in the housing, axially spring-loaded in the axial-directional recesses with the possibility of longitudinal movement of pins with working and false grooves, locking elements housed in the core. the core and the annular groove of the core with the possibility of placement in the grooves of the pins, and a push key, characterized in that, in order to increase the reliability of operation, the pins are made flat and are installed with the possibility of radial movement by means of the flat springs placed in the recesses of the core, while in the axial direction they spring loaded through a single coil spring. f IS J i l §§Р -е2- h h G, at  , .1-1L Jar 7777/777 // A kto -fe -f -f ® t, rhhhhhh lh / . / and I th Gpuli ft - And Ftg fi ft at qput 3 & i c f . f f idL I 2 f fU ..4  4 IS / I rjai -.f YU cput
