Abstract

1. Code lock, comprising a housing with a key guide, a bolt mounted in the housing, mounted for longitudinal movement, a bolt movement mechanism including an external rotary control member associated with the bolt, a code node including locking code disks with radial grooves installed in the same plane on parallel axes and connected with them composing code disks, and a key, characterized in that, in order to increase the convenience of operation and simplify the design, the guide the key consists of two grooves located on both sides of the code node and along the axis of the code disks; the direction of movement of the bolt, while in the bolt and the bracket are made coaxially with the key guide through grooves for the passage and placement of the key and ensuring the engagement of the bracket with the bolt through the key, the bolt is spring-loaded, and in the case wall there is a hole for the exit of the key, the axis of which is located from the axis of the key guide at a distance corresponding to the movement of the bolt. 2. A lock according to claim 1, characterized in that the key is in the form of a pin. (Best regards)

Description

The invention relates to locking devices, in particular to a code lock, which can be used to lock service and residential premises.

The aim of the invention is to improve the usability and simplify the design of the lock.

FIG. 1 shows the view, general view; in fig. 2 is a section A- / V in FIG. one; pas figs. 3 section bb in fig. 1.

The key bill of lading contains a root 1 with a guide 2 for a key, a bolt 3 mounted in the housing, installed with the possibility of a neurodigital alternation, a displacement crossbar mechanism including an external rotary control () p1 an 4 connected to the rig; 1, code node ;;, including locking code disks 5 with radial grooves 6, connected to it. And typesetting code disks (not shown) and key 7. Guide 2 for, the soil consists of two troughs 8 and 9, located but both sides of the code node and along the axis of the code disks, radial grooves 6 the coded discs are made through for the passage of the key 7, and the outer rotary control member 4 is connected to the bolt 3 by means of a spring-loaded spring 10 of the bracket 11, which is mounted in the housing with the ability to move in panralepia, but the bolt and bracket are removed. along the key guide, the through grooves 12 and 13 for passing and positioning the key 7 and ensuring the engagement of the bracket 13 with the bolt 3 by means of the key, the bolt is spring-loaded with a spring 14, and an opening 15 is made in the housing wall, the first axis is spaced from the guideway for the key at a distance corresponding to the move rig ate.

K. 1uch 7 code interchange, issued in the form of a shift.

The lock works as follows.

To open the lock, each code disk 5 is set to a specific code value 5 by using dials.

attachment The rigorous fixation of the disc is achieved by the presence of a spring retainer 16 and corresponding recesses at the end of the disc. At the same time, the radial grooves 6 of the code disks are set up on the same axis with the direction 1 and 8 and 9 for the key, as well as with the grooves 12 and 13 of the bracket 11 and the transom 3. In this case, the entrance hole an outgoing door (not shown), a key () 7 is inserted, which locks

0 bracket 11 and bolt 3 for collaboration. By turning the outer organ 4 control, the disk 17 rotates, which interacts with the clamp 11, moves the clamp 1 1 and the bolt 3 with this lock. The lock opens. This is by: the application for. After a short lap of the grip on the end of the girder, the key 7 falls out of the lock body through the opening 15. When you turn () to the initial position and iod, the return springs of the grip and the transom will be

0 return 1, epi in the original position. Opening the lock from the inside is achieved by turning the inner handle 18 into one side through 180 °. At the same time, it interacts with the disk 19, having a protrusion 20, which is included in the groove 21 of the transom. The bracket in this case does not move.

To change the lock code, you need to change the position of the outer coding discs relative to the locking discs. This is achieved by twisting the connecting rods 22, 1 of which are made of a soft metal, for example aluminum.

If the code is incorrectly typed, the pin will not get into the carrier of the lock, but it will drop out of the housing 1 into the traps through the holes 23 left and right. The bracket in this case is with the rig-. The frame is not blocked and freely moved by the outer control, not carried along by the bolt.

This zombie allows most of the 0 parts of the code 1-; aeti to be made from different; first n,: mass, which is achieved by saving the metal.
