Description

The proposed control locking device, intended both for locking the pivot stop bars on railway tracks and for locking the doors, is a type of two-key locks that cannot be removed at the same time. In FIG. 1 depicts an external view of the lock of thrust railway bars; FIG. 2 - lock cover, FIG. 3 shows the lock from above, FIG. 4 is a view of the lock without a cover; FIG. 5 - the same, without the creeps, FIG. 6 is a section along the line BB in FIG. 4, FIG. 7 shows a section along the line 5-5 in FIG. 4, FIG. , figs. 9-pin lock, FIG. 10 is a front view of a stop bar with a lock; FIG. 11 is the same, top view, FIG. 12 is a section along line AB in FIG. 10, FIG. 13 is an external view of a lock adapted for locking doors; FIG. 14 is the same, view from one and the other side, FIG. 15 is the same, top view in the locked position, FIG. 16 is a front view of an unlocked lock and FIG. 17 is the same, top view. The lock consists of the following parts: a box with an internal mechanism, a pin D and a key K. The box B of the lock is attached to the C-pillar with screws O; In cover A, there is a keyhole 3 for key K, and in the lower part a hole W is made for insertion of pin G. To prevent clogging, the keyhole 3 is covered with an AND plate, which can turn to the side (Fig. 1-3). There is a flange P around the bottom hole Ж, which is slightly protruding in its upper part, forming a visor protecting the parts under it from rain. Pin D is wound at one end in the form of a key barb (Fig. 9). At the other end of it, there is a short pull of tail B, which can freely rotate on the pin, but cannot be removed from it, and is one inseparable part with the pin. In the middle, the pin is attached to a round plastic A, which serves to cover the opening in the lock. The blade and flange prevent any objects from penetrating into the interior of the lock while the pin is in the lock. The lock box is fastened to a rack C dug into the ground against which the free end of the bar rests, and the bolt B of pin D is attached to the free end of the bar with bolt b (Figs. 1, 3 and 10). In order to easily remove the pin from the lock, the eye of the bolt b, to which a short pull is attached, is made with an elongated hole. Box B consists of a cast-iron board with tides l, l-, m, m ,, f, Oi and two pins Oz and 0 are attached to it, on which nazivivak ts key K and pin G. On tides l and l rests cover A of the box of the castle, in the tides of the same l, m and m there are recesses in which the half-numbered P and 1 are placed. The grooves for the pin are the pin g and two are the grooves U and Yu, which include the tide I, which is found in I / 1 tsugalts (Fig. 4 and 5). The stops II, HI and p. Allow the key K and the pin D to be rotated only up to a certain limit. A spring rests on the tide F, connected to the zugaltoe M Shch, the axis of rotation of which is the tide Oi. In addition to P.'s spring, there is also a Jaz spring acting on zugalt I (,, rotating on the axis O. When pin D is inserted into the lock and key K is removed, parts of the lock will be in the position indicated in the drawing. In this position the pin cannot be removed, since when turning it will rest against the inflow of H, or into the slider H1, which it cannot move due to the fact that the lower end of the slider H enters the recess T, which is in the slider Hc- In order to remove the pin r, it is necessary to insert the key K and turn it; at the same time the beard of the key K will raise the creep the lower end of which will come out of the recess T; the slider P will be able to be moved and the pin D can be turned and removed. After that the bar will be in a free position and it can be moved aside. But at this time the slider I cannot be lowered , since its lower end will not be against the recess T, and turning the key K will rest against the upper edge of the slider I. The key K can be removed after pin D is inserted into the lock and turned into the position shown in the drawing e, for which the bar must be put in the closed position. The action of zugalt u and i does not require an explanation. To make it difficult to forge a key, you can make several zugalt with cuts of different depths. When using the described lock to lock the doors, the box B, the lock is attached to the door braid, and the hinge plate A with screws O, O to the door leaf. In the lining 1 pin G is rotatably fixed (Fig. 13, 14, 15 and 17). With sliding doors, on the other hand, the cover of the box BI is provided with a protrusion M which fits into the recess MI provided in the cover A (Figs. 16 and 17). SUBJECT OF THE PATENT. 1. A control box lock for locking the pivot stop bars on railway tracks, characterized by the use of boxes located in box B (Fig. 5 and 4): the slider fJi, which is guided by the tides M and M, is held by the spring-clover U and is twisted by turning through the hole W (Fig. 2) in the lid A of the lock pin G (Fig. 3, 9 and 6) until the beard meets H, (Fig. 5, 4), and locking it with its protrusion at the lower end of the second half slider P which is guided by tides L and L ,, held by spring zugalto m u and is moved by turning the key K passing through the hole 3 in the same lid A (fig. 8) until the beard meets its stop H, at which the box B and the lid a with bolts are attached to the fixed stand C (fig. 12 ), and pin G with the help of tg B and bolt b (Fig. 3 and 12) to the rotary bar, or vice versa. 2. Modification of the lock described in paragraph 1, intended for locking the doors, characterized in that pin D (fig. 13-17) is pivotally fixed in the cover A attached hingedly to the braid or door leaf, and in the case of sliding doors doors, the cover plate A may be provided with a notch M (Fig. 16 and 17), corresponding to the projection MD on the lid of the lock.
