Description

 The invention relates to locking devices, in particular to a padlock, which can be used to lock rooms, as well as an element of an anti-theft device.

 In cipher (code) locks, the secrecy and reliability of locking is determined, ceteris paribus, by the minimal reaction of the deadbolt or other locking elements of the lock to the selection of the code when turning the cipher delays (elements) under tightness. There are various ways to reduce this reaction due to the introduction of additional bolts into the lock mechanism, the use of the complex movement of the bolt when opening, and others.

 A cipher padlock is known (USSR aut. St. N 578414, class E 05 B 37 / 14.1976), comprising a housing in which a spring-loaded deadbolt is located, having segment recesses for cipher disks, a locking arm and a cylinder on the side surface mechanism with a key.

 In this castle, the selection of code is difficult, but possible. To do this, it is enough to turn the cylinder mechanism using the master key to apply a constant force to the bolt to unlock. Then, “to the touch”, the cipher disk is determined, which sits most tightly, and by enumerating the options, the position is set at which the response on the master key will be maximum. Thus, while maintaining the mechanical interaction between the unlocking element and the encryption disk, it is always possible to select a code with sufficient qualification of the cracker.

 Known padlock door lock (USA, US Pat. N 4829794, CL T 05 B 37/02, 1989), containing a body having an internal cavity, a handle with short and long legs and slots associated with the cavity. Slots fit digital discs. On the long leg of the arm, the tumblers are mounted with the possibility of rotation and digital discs through the connecting parts.

 This castle is the closest to the proposed solution in terms of the number of common features and can be taken as a prototype.

 The lock has a mechanism for changing the code combination. In the proposed design, identical toggle switches are installed between the long leg of the handle and the digital disks, which really help to increase the security of the lock. However, in this case, there is the possibility of determining the correct position of the digital disk by the reaction of the lock handle when selecting the code, because due to the always existing tolerances and inaccuracies in the manufacture of the handle, the handle is kept tightly closed by all toggle switches. As a result, sorting through all the positions of the digital disks when the arch is tightened, one can use the indicator or touch to determine the open position of the toggle switch that held the arch most tightly by the reaction of the arch.

 The technical result of the invention increase its secrecy in combination with ease of use, as well as manufacturability.

 The achievement of the technical result is due to the fact that in the padlock, the lock containing the housing with a bolt located in it, having grooves for encryption delays, the lock housing is made in the form of a rotating clip with a window and a shoulder, in which, when the axis of rotation of the delays coincides with the window in the cages of the delay have the possibility of rotation and at the same time the bolt is fixed by a shoulder from axial movements, and when the cage is rotated to a different position, the bolt is released and the rotation of the delays is excluded, the latter being set to grooves with gaps known to be larger than a shoulder.

 The use of a bolt tightly held by the shoulder when typing the code in the locking device and delays turning in the grooves of the bolt that do not touch their walls satisfies the requirements for the "novelty" criterion.

 The proposed solution meets the criterion of "inventive step" due to the increased secrecy of the locking device, the ease of use of an easily disassembled design with manufacturability.

 Increasing the security of the lock is ensured by the fact that the cracker is not able to determine the correct position of the delays arbitrarily rotated and knocking down the lock code, nor by changing the force (its reaction is the same), because they, turning in the grooves of the bolt, do not touch their walls, nor by the reaction of the bolt (for the same reason).

 The proposed design of the lock is easily disassembled and convenient to operate. To do this, just enter the code and remove the deadbolt, then remove the screw that keeps the lock body and the insert from turning, and turning the latter relative to the body, remove the bead through the recess (necessary to install the deadbolt and remove the insert), thereby removing the insert from the body .

 Based on the foregoing, we can conclude that the claimed technical solution meets the criterion of "industrial applicability" and can be used in industry, for example, for locking rooms, as well as one of the components of an anti-theft device in transport.

 In FIG. 1 shows a castle, general view; in FIG. 2 same, top view; in FIG. 3 section aa; in FIG. 4 section BB; in FIG. 5 option 2 of the castle, general view; in FIG. 6 option 2 of the castle, section BB.

 The proposed cipher lock consists of a housing 1, a deadbolt 2, a central insert 3, cipher cylindrical delays 4 and a fixing bar 5 with an elastic element 6.

 The housing 1 is made in the form of a rotating clip with a window 7 for access to cipher delays 4 and a shoulder 8, which holds the bolt 2 and insert 3 from axial movements. The end shoulder 8 has a segment recess 9 for installing the bolt and removing the insert when disassembling the lock.

 The bolt 2 has a head 10 for installing a lock in the door hinge and a groove 11 for interacting with delays 4, the latter being located in the grooves with obviously larger gaps than the shoulder 8.

 The insert 3 has an annular groove 12 with a shoulder 13 for interaction with the shoulder 8 and a cylindrical, eccentrically located channel 14 for installing the bolt 2 and the hole 15 for setting delays 4.

 The delays 4 are made with radial grooves 16, interacting with the strap 5, and a slot-indicator 17. At the delays there are cylindrical samples 18, coinciding in one of the fixed positions with the channel 14.

 The lock body and insert are kept from turning by screw 19.

 In the second embodiment of the lock, the delays 4 can be equipped with a numbered disk 20 located outside the lock case and connected to the delay by a transition with an octagonal cross-section 21. In this case, an additional groove 22 is made in the casing of the cage, in which, when the cage is rotated, a transitional delay section is placed, the width the groove eliminates the possibility of rotation delay in it.

 The castle operates as follows.

 The housing 1 is rotated so that window 7 allows access to delays 4. Then, through the window 7, a key is inserted into the slot 17 and the delays are set in accordance with the lock code to the position where the samples 18 coincide with channel 14. After dialing the code, the housing 1 rotates to coincidence of the recess 9 with the channel 14, and in this position, the bolt 2 is inserted into the channel 14 through the loops of the object to be locked. The housing rotates to its original position, while the shoulder 8 enters the groove 11 and tightly holds the deadbolt 2. Knocking down delays 4 Xia code and closed the lock.

 The lock opens in the reverse order.

 Since when entering the lock code, the bolt 2 is tightly held by the shoulder 8 and the delays 4 rotate in the grooves 11 without touching their walls, the cracker cannot determine the correct location of the delays either by changing the force during the rotation of the delays or by the reaction of the bolt. Having released the deadbolt 2 by turning the housing 1, you can only make sure whether or not the dialed combination matches the lock code.
