Description

The invention relates to locking devices, in particular to key combination locks. A key code lock is known, comprising a housing with a cylindrical core mounted in it, spring loaded paired locking pins coaxially located in the radial openings of the housing and chamois. A keynote, spring-loaded digital disks, primary and secondary cipher switches, installed with the possibility of contact with digital disks 1 However, this key code point has insufficient secrecy. The purpose of the invention is to increase the secrecy of the castle. The goal is achieved by the fact that, in a key combination lock containing a housing with a cylindrical core rotatably mounted therein, spring-loaded paired locking pins coaxially located in the radial holes of the housing and the core, spring-loaded disk drives, primary and secondary keys for changing the cipher, installed with the possibility of contact with digital disks, the core consists of two parts, one of which has spring-loaded locking pins, and the other has a rejection underneath implicit key, wherein the core has at | lenshey least one lock in the form of a leaf spring, scharnirno mounted on one part and contacting the other hand, the basic key set has ttao-. Tin with adjusting marks attached to its beard, and a retainer in the form of a leaf spring, hinged at the end of its stem; moreover, spring-loaded locking studs are provided with adjusting marks corresponding to the labels of the set of plates. Kah FIG. 1 shows the key code. lock, cut; in fig. 2 shows section A-A in FIG. one; in fig. 3-section BB on 31 of FIG. one; FIG. 4 is a section B-B in FIG. la fig. 5 is a view of FIG. 1. The key combination lock has a housing 1 with a core 2 that is rotatable, a bolt 3, a main key 4, no 5 and upper 6 locking pins. The bolt 3 is in permanent engagement with the gear 7 of the core 2, and the stops 8, which are rigidly connected at one end to the upper locking pins, and at the other end can interact with the guide gears 9 mounted on the shaft 10 and having fictitious grooves 1 groove 12 and a tooth 13, which are in engagement with the digital disks 14. The disks 14 are mounted on the shaft 15, have teeth and are spring loaded 17. The disks 14 are driven by forks 18, mounted on the shaft 19 and spring loaded 2O. The forks 18 have a wedge 21, mounted on the rack 22 and having the opportunity to interact through the beards 23 with the additional key 24. The detector 2 is made of two parts of the building ;; 25 and a segment portion 26, one of which has at least one constipation made in the form of a leaf spring 27. The main key 4 is made in the form of a rod 28 of the guide 29 in which the short bead is installed, consisting of a set of plates 30. At the end of the rod 28, there is a hinged fastener in the form of a leaf spring 31. For the possibility of replacing the core 2, there is a cover 32 and a wedge guide 33. In addition, the stops 8 have stops 34. The key combination lock works in the following way. At the door, safe, etc. the lock bolt 3 locks by connecting and entering the recess of the fixed part of the door. The exit of the transom 3 is the closing of the door, and the entry of the transom 3 into the body of the first lock opens the door, for example, a safe and so on. The key combination lock has a digital setting. When the main key 4 is inserted, when all the stops 8 are in the guide grooves 12, the cipher is adjusted by inserting and rotating an additional key 24, which, with its beard, looks at the forks 18, and the digital disks 14 with guides gears 9. Digital disks 14 rotate freely and set the number 894 to the digit, thereby locking the cross over before any locking. In addition to digital coding, the lock has a key code 4 6 locked with locking pins of core 2, for which the cover 32 is removed, the maj spring plates 27 are mated and the segment part 26 is removed and the stops 8 are inserted on the stops 34. After removing the lower locking pins 5, take the main key 4 and he also due to the rotation of the latch 31, remove the plate barbs. The lower lowering pins 5 and AOR plates have paired corresponding mounting marks, due to which in the main key 4 and in the segment portion 26 the pins and pins are set in the same order, and the order of the pair-wise installation can be any. After installation, the constipation 27 and the retainer 31 return to their original position and the segment portion 26 is previously set to its original position. When the main key 4 is still not inserted into the core 2, the upper 6 and lower 5 locking pins are lowered and will limit and 8 out of the working slots 12. Then the digital disks 14 are rotated, thereby showing which cipher has been dialed before, and since the digital disks 14 are in engagement with the guide gears 9, and they also turn so that fictitious grooves 11 are installed in front of the stops 8. For greater secrecy, you can swap places on the main key 4 of the key 4, first remembering in what sequence they were installed us that prevents removal of the impression from the key directly in wine otsutst host. Undesirable opening of the lock is impossible without knowing both the cipher and the plates 30. Even knowing this location, it is impossible to pick up the cipher, since with the wrong cipher dialing, the stops 18 when opening with key 4 will not enter working 12, but fictitious grooves 11 of guide shears 9. Open key lock combination, with the correct set of plates 30 of the main key 4 and the code correctly typed using digital disks 14. Insert the main key 4 into core 2, and since opposite to the working guides 12 they rise and enter into them 8, the lower locking pins 5 are installed in the segment part of the core 2, and the upper 6 in the core.

Well 1, thereby not turning the core 2 and setting the crossbar 3.

The use of the proposed lock prevents unwanted unlocking of objects.
