Description

The author's certificate No. 24727 describes a control lock with a control body closing the free end of the rotary handle, the lock body being provided with a box with a slot for inserting the control seal key and with a spring delay that serves to automatically lock this seal.

In the proposed modification of the control lock, the box used to insert the key into it is provided with spring delays abutting the key lugs. The lock has a doubly complicated control mark, half of which serves as a tear-off duplicate of the mark for comparison with the spine.

In FIG. 1 shows a general view of the lock and the mark in the closed state; FIG. side lock; FIG. 3-type control mark; FIG. 4 - view of the internal structure of the box; FIG. 5-key type; FIG. 6-modification of the castle and the look of it

in the closed state; FIG. 7 — modification of the reference mark; and FIG. 8-view of the castle with ribs.

A lock seal can serve as a control complement to all kinds of locks and bolts; the sealing of the proposed lock is made without the use of clasps and lead seals, the latter being replaced by marks (Figs. 3 and 7), which are made from pieces of tin, paper, cardboard, plywood and other cheap material.

Sealing is performed as follows. For the lock (Fig. 1), a thread is taken, the ends of which are tied into one knot, thread through the ears of door breakdowns, and doubly folded together with the knot are placed inside box 4 in slot 9 and the lid is closed; so that the latter does not open, put a control mark on the protrusions of U (Fig. 3 or 7), but first put the mark

: stamp of any form or make an appropriate inscription. Mark 7 can be folded double and put on protrusions 10, but it is better to cut off half of the mark along the line of the dotted line and save it for comparison with the spine as a duplicate. After that, the key 5 is pushed into the box 4, where the spring delay / 7 (Fig. 4) snaps the key and will not give it the reverse output; the lock seal will be securely closed, and the mark of the mark will be clamped between key 5 and box 4. When the seal is removed, the control mark breaks or breaks (if it is paper or cardboard), after which the lock opens.

The embodiment of FIG. 6 differs from the first in that the knot of thread, once tied, is hidden inside the box 4 and the end of the thread is connected to the key 5; the latter, during sealing, is passed through narrow slits of the breakdowns specially made for this purpose and is also closed.

Box 4 (FIG. 4), which is used to insert the key 5 thereto, is provided with spring delays, abutting the protrusions 12, 12 of the key (FIG. 5). When clamping, there is a doubly folded control mark 7 (Fig. 7), half of which serves as a fragmentary duplicate mark for comparison with the spine.

The subject matter of the invention.
