Description

Technical Field

[0001] The utility model relates to the field of subway compartment doors, in particular to a side door of a subway driver's cab. Background Art

[0002] The side door of the subway driver's cab is usually used for evacuation and rescue in emergency situations. In an emergency, if there is a problem inside the subway car, such as a fire, evacuation, or other situation that requires the rapid evacuation of passengers, the driver can leave the driver's cab through the side door and then guide the passengers to evacuate to a safe area through the side door. This design helps improve the safety and emergency response capabilities of the subway system.

[0003] In the prior art, a Chinese utility model with a comparative announcement number of CN218406992U discloses an opening and closing device for a side door of a subway driver's cab, which opens and closes the side door by flipping the door open. However, in current practical applications, due to the limitation of tunnel space and for the convenience of automated use, a horizontal sliding door opening method is generally adopted, and the locking effect and shockproof effect of the door body are ensured by electric locking. In some accidents that have occurred in recent years, it was found that although the horizontally moving door body is equipped with an emergency switch structure, the door opening is slow to open in the horizontal door opening method, which still affects the escape speed.

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 5As shown in the figure, the side door of the subway driver's cab includes a door body mechanism 2 for shielding and a fixing mechanism 1 for fixing the door body mechanism 2. It also includes a locking mechanism 3 for locking the door body mechanism 2 and a safety mechanism 4 for quickly releasing the door body mechanism 2. The door body mechanism 2 is installed on the fixing mechanism 1, the locking mechanism 3 is installed on the fixing mechanism 1 and is located outside the door body mechanism 2, and the safety mechanism 4 is arranged on the side of the locking mechanism 3;

[0028] The door body mechanism 2 includes a door panel 21 and a door frame 22. The door panel 21 is installed inside the door frame 22. The locking mechanism 3 includes an opening and closing cylinder 31. The piston rod of the opening and closing cylinder 31 is hinged to connect the door frame 22. Guide wheels 33 are installed on both sides of the upper and lower end faces of the door frame 22. A locking frame 32 is installed on the fixing mechanism 1 outside the guide wheels 33. A release frame 35 is arranged on the side of the locking frame 32 away from the opening and closing cylinder 31. A biting block 36 is installed inside the release frame 35. A cooperating frame 34 is arranged between the upper and lower release frames 35. The release frame 35 is connected to the cooperating frame 34 through the safety mechanism 4.

[0029] In this embodiment, the safety mechanism 4 includes a release screw 41. The release screw 41 is threadedly connected to the release frame 35, and the release screw 41 is a bidirectional threaded rod. A transmission component 42 is connected to the middle position of the release screw 41.

[0030] In this embodiment, grooves for restricting the sliding of the guide wheels 33 are formed on both the locking frame 32 and the release frame 35, and the guide wheels 33 are exposed on the end face of the locking frame 32 close to the release frame 35.

[0031] In this embodiment, the biting block 36 is connected to the release frame 35 through a spring shaft. A pressure rod is arranged on the side of the locking frame 32 close to the release frame 35.

[0032] In this embodiment, the fixing mechanism 1 includes a car body 11 and a fixing frame 12. The fixing frame 12 is arranged outside the locking frame 32. There are two fixing frames 12 arranged up and down. A buffer seat 13 is installed on the side of the door frame 22 away from the cooperating frame 34. The buffer seat 13 is fixedly connected to the car body 11 through bolts.

[0033] In this embodiment, the locking frame 32 is movably connected to the fixing frame 12.

[0034] In this embodiment, the biting block 36 is in a "C" - shaped structure, and the upper half of the biting block 36 presses against the pressure rod of the release frame 35, and the lower half of the biting block 36 abuts against the guide wheel 33.

[0035] Working principle: Because the space in the tunnel is limited and for ease of use, in normal use, the door frame 22 and the door panel 21 are pulled by controlling the opening and closing cylinder 31 to open and close the door panel 21, and when the door frame 22 is moving, the guide wheel 33 slides in the groove inside the locking frame 32, and when the door frame 22 is closed, the guide wheel 33 squeezes the bite block 36 so that the upper half of the bite block 36 presses the locking frame 32, so that the locking frames 32 on the upper and lower sides clamp and close the door frame 22, thereby reducing the abnormal noise generated during the movement of the subway and ensuring the sealing.

[0036] When the door needs to be opened urgently, the transmission assembly 42 is manually rotated to drive the release screw 41 to rotate, so that the release frames 35 on the upper and lower sides move upward or downward respectively, and the release frames 35 are separated from the guide wheels 33. At this time, only one guide wheel 33 is stuck in the groove of the locking frame 32, pushing the door panel 21 so that the door panel 21 can be flipped open, thereby improving the door opening efficiency.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
