The built-in manual sliding door often gets damaged when in use. When damaged, the built-in manual sliding door cannot be fully closed, and the subway driver's room side door cannot be closed to a specified position. After being closed, a large gap is left, which seriously affects the driving safety of the train.

[0003] Therefore, how to provide a subway driver's room side door locking device capable of closing the subway driver's room side door to a specified position when the built-in manual sliding door is damaged and locking the subway driver's room side door is a problem that those skilled in the art need to solve urgently. SUMMARY

[0004] Therefore, the utility model provides a subway driver's room side door locking device, aiming at solving the problems in the above background art and achieving the closing of the subway driver's room side door to a specified position when the built-in manual sliding door is damaged and the locking of the subway driver's room side door.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A subway driver's room side door locking device comprises:

[0007] A fixing ring is arranged on the side of the frame of the subway driver's room side door.

[0008] A latch is inserted through the fixing ring. The latch is perpendicular to the plane where the subway driver's room side door is located. One end of the latch is inserted into the gap between the subway driver's room side door and the door frame. When in use, the latch blocks the sliding of the subway driver's room side door towards the door frame of the side door. The end of the latch inserted into the gap between the subway driver's room side door and the door frame is provided with a wedge-shaped head.

[0009] A handle rod is arranged on the side of the latch away from the subway driver's room side door. The axis of the handle rod is perpendicular to the axis of the latch.

[0010] Further, anti-rotation plates are arranged on the upper and lower sides of the latch. The anti-rotation plates are rectangular and symmetrically arranged on the latch. The side of the anti-rotation plate close to the wedge-shaped head is provided with a wedge block.

[0011] Furthermore, a rotating groove is provided at the end of the pin that is connected to the handle, and a rotating shaft is provided on the handle, the rotating shaft rotating within the rotating groove.

[0012] Furthermore, a central screw hole is provided on the rotating shaft, the axis of the central screw hole is the same as the axis of the rotating groove, a screw is provided in the central screw hole, one end of the screw abuts against the inner wall of the rotating groove, and the other end of the rotating groove extends out of the central screw hole.

[0013] Furthermore, two fixing rings are provided, and fixing screw holes are provided at the top and bottom of the fixing rings.

[0014] Furthermore, the handle is provided with an arc-shaped rod, both ends of which are fixedly connected to the handle.

[0015] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a locking device for the side door of a subway driver's cab. By setting a latch, one end of the latch can be inserted into the gap between the side door of the subway driver's cab and the door frame during use. The latch can prevent the side door of the subway driver's cab from sliding into the door frame during use, and can lock the side door of the subway driver's cab to the door frame. Thus, it can close the side door of the subway driver's cab to a designated position and lock the side door of the subway driver's cab in the event of damage to the concealed manual sliding door.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 This utility model discloses a locking device for the side door of a subway driver's cab, comprising:

[0024] A fixing ring 1 is provided on the side of the driver's cab side door frame 2. There are two fixing rings 1, and fixing screw holes 11 are provided at the top and bottom of the fixing ring 1. In this embodiment, the fixing ring 1 is used to fix the pin 3 to the driver's cab side door frame 2. By setting two fixing rings 1, the pin 3 can be fixed horizontally, which can effectively prevent the pin 3 from sliding up and down and ensure the safe use of the pin 3.

[0025] A latch 3 passes through a fixing ring 1 and is perpendicular to the plane of the subway driver's cab side door 4. One end of the latch 3 is inserted into the gap between the subway driver's cab side door 4 and the door frame 2. When in use, the latch 3 prevents the subway driver's cab side door 4 from sliding into the door frame 2. A wedge-shaped head 5 is provided at the end of the latch 3 that is inserted into the gap between the subway driver's cab side door 4 and the door frame 2. In this embodiment, by setting the latch 3, one end of the latch 3 can be inserted into the gap between the subway driver's cab side door 4 and the door frame 2 when in use. The latch 3 can prevent the subway driver's cab side door 4 from sliding into the door frame 2 when in use. The latch 3 can lock the subway driver's cab side door 4 to the door frame 2, thereby enabling the subway driver's cab side door 4 to be closed to a designated position and locked when the concealed manual sliding door is damaged.

[0026] A handle lever 6 is provided on the side of the latch 3 away from the side door 4 of the subway driver's cab, and the axis of the handle lever 6 is perpendicular to the axis of the latch 3. An arc-shaped rod 12 is provided on the handle lever 6, and both ends of the arc-shaped rod 12 are fixedly connected to the handle lever 6. In this embodiment, by providing the handle lever 6, the latch 3 can be easily driven. Pushing the handle lever 6 can insert the latch 3 into the gap between the door frame 2 and the side door 4 of the subway driver's cab, thereby fixing the side door 4 of the subway driver's cab. By pulling the handle lever 6, the latch 3 can be removed from the gap between the door frame 2 and the side door 4 of the subway driver's cab, thereby opening the side door 4 of the subway driver's cab.

[0027] Anti-rotation plates 7 are provided on both the upper and lower sides of the pin 3. The anti-rotation plates 7 are rectangular and symmetrically arranged on the pin 3. A wedge block 8 is provided on the side of the anti-rotation plate 7 near the wedge head 5. In this embodiment, by providing the anti-rotation plates 7, the pin 3 can be prevented from rotating circumferentially, thereby ensuring that the pin 3 is firmly inserted in the predetermined position.

[0028] A rotating groove is provided at one end of the pin 3 connected to the handle 6. A rotating shaft 9 is provided on the handle 6, and the rotating shaft 9 rotates within the rotating groove. A central screw hole is provided on the rotating shaft 9, and the axis of the central screw hole is the same as the axis of the rotating groove. A screw 10 is provided in the central screw hole, one end of which abuts against the inner wall of the rotating groove, and the other end of the rotating groove extends out of the central screw hole. In this embodiment, by providing the rotating shaft and the rotating groove, the handle 6 can be rotated during use, making it convenient to use. The handle 6 can be rotated to a convenient position for use. By providing the central screw hole and the screw 10, the handle 6 and the pin 3 can be fixed after rotating the handle 6, which can effectively improve the efficiency of the device.
