Description

Technical Field

[0001] The present application relates to the technical field of elevator door opening holding devices, and in particular to an elevator door opening holding device. Background Art

[0002] Elevators are the product of social development and progress. With the continuous development of social economy, there are fewer and fewer low-rise houses, and more and more high-rise buildings are rising from the ground. This has led to a sharp increase in the use of elevators, because all high-rise buildings cannot do without elevators. Elevators provide convenience for people's travel and can also be used to quickly move things, greatly saving people's manpower and time costs. This is the basis for the normal operation of modern high-rise buildings. During the operation of the elevator, passengers can open the elevator door by pressing the door opening button. However, this button will automatically reset after pressing, which means that the elevator will not keep the door open because the button is pressed. Within a few seconds, if there is no operation, the elevator will automatically close the door. This design improves the operating efficiency of the elevator to a certain extent, reduces the number of times people need to press buttons when taking the elevator, and thus shortens the waiting time.

[0003] However, this operating mode also has certain defects. Since the elevator cannot keep the door open without continuously pressing the door opening button, this brings inconvenience to certain specific occasions. For example, when the elevator needs to transport goods, if the goods are large or large in size, then someone is required to be responsible for pressing the elevator door opening button to allow the goods to enter the elevator smoothly. This not only increases labor costs, but may also cause elevator failure or personal injury due to improper operation. In addition, some people may try to block the elevator door with goods to prevent the elevator from closing. However, this approach also has risks. Smaller items are easily squeezed by the elevator door, while larger goods may hinder entry and exit of the elevator and even affect the normal operation of the elevator.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
