Abstract

The invention is intended primarily for locking wagons and containers for rail transportation, and can also be used in production and in everyday life and allows for increased secrecy and reliability of the lock. Making at least one groove at the locking end of the handle, and a notch located at each of the pins at different distances from the threaded portion at the cylindrical section of the locking pin ensures the security of the lock. In addition, the placement of the threaded section of the channel of the housing between the ends of the handle eliminates the turning and, therefore, unlocking of the lock, which increases the reliability of locking. 4 il.

Description

The invention is intended primarily for locking wagons and containers for rail transport, and can also be used in production and in everyday life.

The aim of the invention is to increase the secrecy and reliability of locking.

FIG. 1 shows a lock, a cut; . 2 is a section A-A in FIG. one; ra. FIG. 3 is a section BB in FIG. one ; in fig. 4 - section bb In Fig, 1.

The new lock includes a housing 1 in which vertical parallel through and blind holes are made to accommodate the ends of the handle 2. Horizontally in the housing 1 there are two intersecting vertical holes of through through cylindrical channels, each of which includes two smooth sections of different diameters connected by third - threaded. At one of the ends of the arms 2, horizontal grooves 3 are made, the axes of which are parallel to the respective axes of the channels in the housing. Inside the channels there are pins 4 with a threaded section 5 and a slot 6, a smooth cylindrical section 7 with a head 8 in the form of a triangular turnkey prism. The length of the cylindrical section 7 of the pin is greater than the length from the beginning of the threaded section in the channel of the housing 1 to the end of the groove 3 in the arch 2 to eliminate the possibility of unlocking the lock when the pin is fully inverted (at its leftmost position). On the cylindrical section 7 of each pin 9 depth equal to but not less than the depth of the groove 3 in the bow 2 (otherwise the lock cannot be assembled, i.e. locked), and the depth of the groove 3 cannot be greater than the diameter of the cylindrical section 7

pin The shape of the grooves 3 provides a reliable fixation of the arms 2 in the housing with pins, and the shape of the recesses 9 provides for unlocking the lock. In addition, the notches 9 on the cylindrical sections 7 of each pin are made at different distances from the threaded sections 5, which ensures a certain degree of secrecy of the lock, i.e. is its code. When using a set of pins with different distances for making the notches 9, the lock code is changed, which means that its reliability is increased. Performing the threaded section in the channels of the housing 1 between the ends of the arms 2 and placing the threaded sections 5 of the pins on it allows, after assembling the lock, to exclude the possibility of reversing the pins from the housing, i.e., to prevent its unlocking.

The execution of channels in the housing in one plane and parallel, as well as the execution of grooves 3 on one end of the bow 2 and on one side of it (Fig. 3) and the installation of pins on one side (left) in the housing (Fig. 2) simplifies the manufacturing process and lock assembly.

In case 1 and at one end of the handle

2, apertures 10 for sealing are made.

The lock is assembled as follows.

Two pins are preliminarily taken, each of which in the cylindrical section 7 has a notch 9 at a certain distance from the threaded section 5. For example, this distance corresponds to an integer number of revolutions of the pin from the extreme right position at which the groove sections

3 and notches 9 on the handle 2 and the pin are the same. This distance is the pin code and is marked, for example, on the threaded section 5 as a digit, which is recorded in a journal or other document before the assembly. Sequentially, each pin with a screwdriver through the slot 6 in section 3 is screwed

into the through channels of housing 1 (left) up to the stop of sections 5 into the right cylindrical section of the channel in the housing, then each pin is turned to the left for a given number of about-55 rotations with an allen key with a triangular hole on the right. dial the specified code of each pin, in which the notch 9 of each pin coincides with the profile of the hole in the housing 1 under the bow 2,

In this position, the sections 5 of both pins are located between parallel branches in the housing 1 under the ends of the arms 2, and the arms 2 are inserted into them, one end of which with the slots 3 freely lowers into the blind hole in the housing 1 " and rests on its bottom. Then, screwing or twisting each pin in succession, insert their cylindrical sections 7 into the corresponding grooves of the handle 2 and fit it into the housing 1. The lock is locked.

To unlock the lock, you need to turn the pins 8 in succession with the key 8 until the stop of the threaded sections 5 into the right cylindrical section of the channel in the housing 1, then rotate the pins in the other direction for a given number of revolutions corresponding to the code of each pin, while matching the grooves 9 and grooves 3 pins and handle 2, respectively, o Since the length of the cylindrical section is greater than the length from the beginning of the threaded section of the channel to the end of the handle 2 with grooves 3 in the housing, when the pin is turned all the way into the left end of the handle 2, the cylinder Its site is in contact with the groove 3 of the arm and, accordingly, prevents pulling out of the arm 2. Moreover, since the threaded portions of the channels are made between the ends of the bow, the possibility of completely removing the pins from the housing is prevented, as this prevents the left end of the bow from which Section 5. Thus,

Therefore, unlocking of the lock will occur only when the slots 3 and the notches 9 coincide, i.e. pin code set. The right end of the handle 2 is released from the pins, and the handle 2 is pulled out.

To eliminate the possibility of unlocking more than one key at the same time, which can facilitate the selection of the code, the lock can be equipped with a locking device, made, for example, in the form of a locking paw 12 placed on the slot of the case between the key holes on the axis 11,

The use of the invention will improve the reliability of locking the lock by ensuring its secrecy
