Description

technical field

[0001] The invention relates to the technical field of hardware devices, in particular to a fire electromagnetic door stopper and an installation method thereof. Background technique

[0002] With the continuous enhancement of people's awareness of fire protection, people's understanding of the importance of fire doors is becoming more and more profound, and the demand for fire doors is also increasing. But in actual use, many people find that it is very troublesome to use the fire door alone. Not only must it be kept open at ordinary times, but also it must be closed in time in case of fire. It is time-sensitive and cannot meet the needs of use in real life. Contents of the invention

[0003] The purpose of the present invention is to provide a fire-fighting electromagnetic door stopper and its installation method, which is applied to the electromagnet of the automatic door, and uses the electromagnetic principle to generate suction to position and switch...
