Problems solved by technology

Although safety is guaranteed in this way, in some devices, such as interior doors, cabinets, bathroom cabinets or various indoor drawers, the safety risk is relatively small, and the safety requirements are actually not high. The door cannot be turned open at will; or, for devices with safety requirements such as anti-theft, such as the door at the entrance and exit of the room, sometimes frequent entry and exit in a short period of time, the safety risk is also small, in this case, if it is locked, A key is required for each opening and closing, which makes the process more cumbersome and inconvenient

However, if the lock is not installed, or if it is not locked after each use, these items may move due to poor installation or fixation, or be moved due to accidental contact, and need to be reset frequently
