How to Open the Door of a Mobile Toilet

The method of opening the door of a mobile toilet varies depending on its type, as detailed below:

Ordinary toilet door without key locking If a child locks the door from the inside, you can try the following methods:

1. Tool-assisted unlocking: Use a flat tool such as a flat-head screwdriver or a spoon. Insert it into the keyhole slot of the lock core, and slowly turn it left and right to find the direction in which it can rotate. Then, rotate it 90 degrees to try to open the door. You can also place a coin in the keyhole slot and rotate it, or use a screwdriver to turn the groove on the outside of the door.
2. Combined operation unlocking: While rotating the outer groove of the door with the handle of a spoon, press the door handle to unlock the door through mechanical linkage. These types of doors usually have a simple structure, so avoid using excessive force to prevent damage to the lock.

Toilet door in second-class seats on high-speed trains There are three operating methods according to the design type:

1. Electric version: Press the switch button outside the door, and the door will automatically slide open. After entering, you need to press the door again from the inside to close it and activate the "occupied" reminder switch (usually a red button) to prevent the door from being opened from the outside by mistake.
2. Sliding version: Open the door through the side folding structure. When closing, operate the internal safety bolt (such as a sliding lock) to ensure the door is fully locked.
3. Handle version: When the green "unoccupied" sign is displayed above the door, press the door handle to push the door open. After entering, open the internal safety switch (such as rotating the lock core) and close the door from the inside to activate the occupancy reminder.

Contactless automatic sensor toilet door It relies on the linkage control of sensors and steering gears:

1. Entry process: The ultrasonic sensor outside the door detects someone approaching, and when the internal sensor confirms that there is no one inside, the steering gear drives the door to open automatically and then close automatically after 2 seconds. You can also manually open the door by pressing the button on the side of the door.
2. Exit process: Three seconds after using the toilet, the steering gear detects that there is no one inside and automatically opens the door. If you need to leave early, you can directly press the button to trigger the door to open.
3. Status indication: When the toilet is occupied, the display screen outside the door shows a red "×" sign. At this time, the sensor will block external door-opening requests to avoid conflicts.

Precautions:

• Confirm the type of the door before operating to avoid using the wrong method and causing equipment failure.
• After closing the toilet door on a high-speed train, check whether the safety device is activated to prevent it from opening automatically during operation.
• If the automatic sensor door malfunctions (such as remaining closed), contact the staff for handling. Do not forcefully push or pull it.
