The invention relates to padlocks of the laid-on type and can be used for locking the doors of cars and containers.

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

Figure 1 shows the locking device in the closed position; figure 2 is a view of And figure 1; on fig.Z - section BB in figure 1; figure 4 - disks locking device; figure 5 - section bb in figure 1 on the corus in an enlarged scale; figure 6 - locking device in the open position.

The locking device includes a housing 1, a lid 2 with a pusher 3. The lid is pivotally connected to the housing 1. In the upper part of the housing, made in the form of a glass, the disk 4 is permanently placed with radial slots 5, in the lower part of it there is a rotatable hollow cylinder on the ledge 6 7. In the upper part of it there are two radial slots 8. These slots are multivariate (in Figure 4 three variants of the drawings of slot 8 are shown). The lower part of the movable disk 7 is centrally provided with a protrusion 9 having a toothed surface 10. A hollow rod 11 with a steering wheel 12 is mounted in the cover 2. The lower end of the rod 11 is made toothed to engage the protrusion 9. The rod 11 is held by a bolt 13 screwed into the protrusion 6 On the rod 11 there is a sleeve 14 installed on the floor, at the lower end of which there are retaining cantilevers 15 with locking lugs 16, and a turning handle 17 is fixed at the upper end. The floor of the sleeve 14 is supported on the cover 2 by the washers 18 and the spring 19 using levers 20 is connected to housing 1.

On the housing 1, the hinge control lever 23 connected by the axis 24 is mounted on the axis 22 by means of a lever 21. The housing 1 is fixed to the wall of the car 25 by bolts 26. The hook 27 is attached to the door of the car 28 by bolts 29. The door has a handle 30, the wall the car is equipped with a plate 31 for recording the cipher of the position of the handwheel 12 and the handle 17 of the closed door of the empty car. The cylinder 7 is provided with a removable key 32 to ensure its rotation.

The device works as follows.

To lock the car door (container), the cover 2 is lowered onto the housing 1, the lever 23 is engaged with the hook 27, and then put to the lowest position until the axis 24 is supported on the push rod 3 of the cover 2.

To bring the locking device to the working position before lowering the cover 2, the cylinder 7 is turned with a removable key 32 to the position until the

the radial slot 8 with the radial slot 5 of the disk 4 of the housing 1. In these combined slots, the holding arms 15 of the cover 2 are inserted. The positions of the steering wheel 12 relative to the letter

designations (A, B, etc.) and digital designations of the handle 17 relative to the steering wheel 12, after which rotation is performed using the steering wheel 12 of the cylinder 7 to any arbitrary angle, too, through the handle

17 turn the holding consoles 15 at any angle. The operation of turning the handwheel 12 and the handle 17 is performed by first pressing down the protrusions 16 of the retaining cantilevers 15 out of the radial slot 8 by pressing the handle 17 and compressing the spring 19. Then the bolt 13 is screwed into the ledge 6. The device is closed. The opening is carried out in reverse order.

Marked alphabetic and numeric

the positions of the handwheel 12 and the handles of the 17 loaded wagons are reported in the accompanying documents, and the empty wagons are recorded on the plates 31.

The advantages of this technical

The solutions are to ensure the safety of the cargo by securely closing the car or container.
