It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.

Referring to fig. 1-4, the present invention provides a subway sliding door unlocking device, wherein the components inside the casing are drawn by dotted lines in fig. 2, which means that they cannot be directly observed from the outside. The drawings are only used for explaining the structural principle of the unlocking device of the subway sliding door and are not in proportion to actual products.

The subway sliding door unlocking device comprises a shell 1, a lock cylinder 2 which is rotatably arranged on the shell 1, a handle 3 which is fixedly arranged on the lock cylinder 2, a vertically arranged lock rod 4 and a trigger plate 5 which is arranged at the top of the lock rod 4; first guiding hole 11 has been seted up at the top of casing 1, the bottom of locking lever 4 passes first guiding hole 11 and stretches into the inside of casing 1 downwards and is connected with a slider 6, handle 3 drives slider 6 through the swing and drives locking lever 4 vertical upward movement.

During actual installation, the shell 1 is installed on a door frame of a sliding door, the trigger plate 5 is arranged opposite to an electromagnetic lock of a subway shielded door system, and under the condition of subway fault or emergency, a passenger on the track side pulls the handle 3 to drive the sliding block 6 to drive the lock rod 4 to vertically move upwards; the lock rod 4 always moves in the vertical direction under the guidance of the first guide hole 11; when the handle 3 rotates in place, the trigger plate 5 triggers the electromagnetic lock to enable the driving door machine to acquire signals, so that the sliding door is driven to be opened. And the staff of the station side can use the special key to twist the lock core 2, and the handle 3 drives the slide block 6 to drive the lock rod 4 to vertically move upwards, thereby opening the sliding door to evacuate passengers or enter the subway carriage for maintenance. Therefore, the subway sliding door unlocking device is simple in structure, convenient to install and high in reliability.

Specifically, as shown in fig. 1 to 3, the housing 1 includes two side plates 13 disposed opposite to each other, a connecting plate 14 connecting the two side plates 13, and a cover plate 12, where the connecting plate 14 is provided with one, the side plates 13 and the connecting plate 14 enclose a U-shape, the cover plate 12 is fixedly connected (e.g., screwed) to the tops of the side plates 13, and the first guide hole 11 is disposed on the cover plate 12. The cover plate 12 is composed of a transverse plate and a vertical plate and is L-shaped; the vertical plate is arranged opposite to the connecting plate 14; the vertical plate can cover part of the inner cavity of the shell 1 to protect the components in the shell 1.

Further, as shown in fig. 3, two limiting convex strips 15 are symmetrically arranged on the inner sides of the two side plates 13, the limiting convex strips 15 are arranged along the vertical direction, the two limiting convex strips 15 and the connecting plate 14 form a T-shaped sliding groove, and the sliding block 6 is slidably arranged in the T-shaped sliding groove. The vertical movement of the lock rod 4 is realized by the movement of the slide block 6 in the T-shaped sliding groove.

As a preferable scheme, as shown in fig. 2 and fig. 3, the sliding block 6 includes a sliding plate 62 and a right-angle block 61 disposed on the sliding plate 62, the sliding plate 62 is slidably disposed in the T-shaped sliding groove, an end surface corresponding to one right-angle side of the right-angle block 61 is fixedly connected to the sliding plate 62, an end surface corresponding to the other right-angle side of the right-angle block 61 is connected to the lock rod 4, and an end surface corresponding to the oblique side of the right-angle block 61 is pressed against the handle 3. Here, one end of the handle 3 is a prying portion 31, and an end surface (i.e., an inclined surface) corresponding to the inclined edge of the right-angle block 61 abuts against the prying portion. By such an arrangement, the friction force between the prying portion and the inclined surface is small, and the slider 6 is more easily driven.
