Description

A magnetic suction device for composite door frame sill

Technical Field

The utility model belongs to the technical field of composite doors, and in particular relates to a magnetic attraction device in a door frame sill used for composite doors.

Background Art

At present, aluminum-wood composite doors and windows are high-end energy-saving doors and windows. Doors and windows are required to meet the specifications. During use, sometimes the gap between the doors and windows is small. Users do not pay attention and think that the doors and windows are fastened. When they are not on site, the doors and windows are not closed tightly or they take the initiative to leave and increase the gap. When there is flowing airflow, the airflow pushes the doors and windows to open or close suddenly. The airflow is even greater in windy weather, causing the doors and windows to be repeatedly opened and closed or even deformed and damaged. The doors and windows are often opened or closed suddenly, and the doors and windows at high altitudes are very dangerous. In severe cases, they directly cause the doors and windows to fall off, and the door and window sashes are difficult to repair and replace. Therefore, users need to check each door and window when going out, which causes a great sense of insecurity for users.

In order to solve the above problems, the prior art has developed a magnetic device inside the door frame sill that can automatically magnetically attract the door panel. However, the existing magnetic device inside the door frame sill can only achieve the adsorption and fixing function when the door panel is completely closed or the magnetic device inside the door frame sill is completely attached. If there is still a gap in the door panel, it cannot achieve the adsorption and fixing effect. Moreover, when the existing magnetic device inside the door frame sill is deviated and misaligned, it is easy to cause the problem of poor sealing.

Through the above analysis, the problems and defects of the prior art are as follows:

The existing magnetic attraction device in the door frame sill cannot play the role of adsorption and fixing when the door panel is not completely closed, and the sealing performance after closing is poor.
