Description

Technical Field

[0001] The utility model belongs to the technical field of elevator equipment and relates to a door opening and holding device for a medical elevator. Background Art

[0002] Elevators are the product of social development and progress. They provide convenience for people's travel and can also be used to quickly move things, greatly saving people's manpower and time costs. When the elevator is running, the elevator is operated by controlling the corresponding command button next to the elevator door. For example, when opening the door, you need to press the door opening button once, but the button will automatically reset after pressing it. After the button is reset, the elevator will not always keep the door open. If there is no operation within a few seconds, the elevator will automatically close the door. The advantage of this working principle is that the number of button presses is small when taking the elevator, and the operation is fast, which reduces the time people spend on taking the elevator; however, this operating mode also has certain defects. The elevator cannot keep the door open without continuously pressing the door opening button. This brings us inconvenience in some cases, especially in hospitals. Hospitals need to use elevators to transport patients or larger equipment. It usually takes a long time to get all the beds, patients on the beds, and medical equipment into the elevator, but the elevator cannot keep the door open for such a long time.
