Description

The invention relates to the internal controls of locks with a detachable handle, consisting of 1 parts of each nested in one another, fastened between themselves by inserting a lock handle in the box. In such locks, it is proposed to use a cartridge inserted into the lock box and held in it by a flat spring pressed inside the box by a cut of the end of the bow locked in the lock with a key, and the cartridge carries a control mark with a known device damaging its mechanism. In order to eliminate the possibility of re-inserting the handle into the lock box without damaging the control mark, a device is provided consisting of two rotary spring wings protruding along both sides of the cartridge. To check the operability of the lock after turning the key, the control plate of the viewing window of the box is intended, moved from the inclined position to the horizontal one.

In FIG. 1 depicts a general view of the proposed lock control lock; FIG. 2 is a front view of the box without a front wall; FIG. 3 is the same side, in section along the line AB in FIG. 2; FIG. 4- front view of the handle of the castle; FIG. 5 the same.

from the side; FIG. 6, front view of the lock cartridge; FIG. 7 is a side view of it; FIG. 8 - type of lock key; FIG. 9-15-types of individual parts amka.

The proposed master control lock consists of a box 20 (Figs. 1-3) into which a handle 7 is laid on top (Figs 4, 5), provided at one of the ends with teeth and in the middle by a tooth 73 to change the distance for the bracket or closed the bag, and the cartridge 77 is inserted at the bottom (Fig. 6, 7). The wings / are pivoted on the axis of the latter, under the action of a spring, protruding beyond the edge of the cartridge and preventing the insertion of the handle 7 without removing the cartridge from the box 20. And the middle part of the cartridge is provided with a plate 23 (Fig. 6. 13, 14) at one end, the hook 2, which engages when the cartridge is inserted into the box with the tooth i2 last (Fig. 2), and at the other end are the knives 27 installed over the bar 6. The latter slides in the slots J8 (fig. b) and are intended for moving down the cartridge tear the control mark imposed on them and hold down frame 4, pivoting on the axis and provided with a withdrawal bracket / 9 (Fig. 6, 7). Inside

box 20 on the axis is placed under the influence of the spring 9 (Fig. 3) hook 8, designed to close the handle 7, and provided at its free end with a finger 8, interacting with the groove 27 of the cylinder 5 (Fig. B and 9) in the cartridge 77 provided at one end with a faceted part 24 (Fig. 9) for a key (Fig. 8), and at the other end with a pin 3, which, when the cylinder 5 rotates, the control plate 77 (Figs 2, 10, 11) of the inclined box in a horizontal position, wherein in an inclined position the plate 77 is held by a spring 22 (Fig. 2 and 12).

Inside the box 20, a flat spring JO (fig. 2) is located on the side, on the free end of which the protrusion 25 of the cartridge 77 is supported (fig. 6), with a plate for keeping the clutch. H is pressed inside the box with a cut 25 at the end of the bow (Fig. 4). For locking the lock, the handle is inserted into the box to the desired depth and automatically snaps into hook S, after which a control mark is placed in the cartridge 77 under the frame 4 and, folding the wing 7, is inserted into the box from the bottom. In this case, the anvil 25 engages with the end of the JO plate (Fig. 2, 6), and the tooth 2 engages with the tooth 72 of the box, thereby locking the cartridge in the lock box.

When the lock is closed, through the window 75 and (Fig. 1) they see the integrity of the control mark, and through the window 14, the lock is in working condition, which is determined by the absence of the plate 77. When the cylinder 5 rotates the cylinder, the latter reverses the plate from horizontal to inclined position J4, and groove 27 (Fig. 9) pulls off hook 8 for finger 8, thereby freeing shackle 7. Thus, the appearance of control plate 77 in J4 indicates that the shackle is open.

After removing the handle from the box, the spring JO, released, releases the cartridge 77, and the latter is pulled down. At the same time, for the entire duration of the advancement, the plate 23 is held by the tooth 75 and the knives 27 tear the test mark.

pledged under frame 4, mixed together with the cartridge. In the final position, the 23 o. Plate is manually freed from the tooth 72 and the cartridge is removed from the box 20. When opening the lock of the cartridge removal base, the control mark is not damaged, and its detrusion occurs when you try to close the lock again by inserting the doo; when there is a cartridge in the lock box, which is ejected at this point and the check marks are destroyed.
