Description

Magnetic threshold

This creation relates to a door gap shielding device, especially a magnetic suction door sill that blocks or opens the door gap by the opening and closing action of the door leaf.

The known door leaf can rotate relative to the door frame. The door frame is larger than the door leaf for smooth rotation and construction of the door leaf. Therefore, there is a gap between the door leaf and the ground, so the sound, smoke, dust, mosquitoes or water outside the door leaf The door gap was used to enter the room, and the door leaf was leaked in terms of sound insulation, smoke prevention, fire prevention, insect prevention, and water resistance, and dust in some areas with serious air pollution also drifted into the house. In the actual portal, there is also a gap between the door leaf and the door leaf or between the door leaf and the upper door frame.

For the above problem, in order to close the gap between the door leaf and the ground, existing products such as US D738,532S, an electric lifting threshold, the electric threshold includes a housing bottom shell, at least one electric lifting device is provided in the housing bottom shell Inside, the lifting device includes an actuating rod, and the internal bar includes a blocking piece and a blocking wall, the blocking wall extends from the bottom side of the blocking piece, the blocking wall further includes a first surrounding wall and a symmetrical second surrounding wall; The accommodating bottom case further includes a first groove and a second groove, the upper side of the first groove has a first opening, the upper side of the second groove has a second opening, and the first groove and the second groove are respectively formed symmetrically on the accommodating bottom On the inner side of the shell, the first surrounding wall can be movably penetrated in the first slot via the first opening, and the second surrounding wall can movably pass through the first Two openings are penetrated in the second slot; thereby, the electric lifting device is opened and operated once. The actuating rod can push the stopper to a distance toward the outside of the open end of the accommodating bottom case to suspend, the electric lifting When the device is turned on and operated again, the actuating lever can return the stopper to its original position.

The problem with these products is that they must use a complex structural system to extend or store the sealing device to close the door gap. Furthermore, the existing products mentioned must use a power supply that is less environmentally friendly. Another problem is that every two doors of a multi-door door There is also a gap between them, and the actuation method of the linkage rod of the linkage device of the existing product described above is also not suitable for actuation in the direction of the closing between the door leaf and the gate leaf; and even if the existing products are installed in each door of multiple doors separately The lower side of a door leaf, when multiple doors are closed at the same time, the sealing devices fall from the lower end of each door leaf together to close the door gap, but there is still a gap between the sealing device and the sealing device, sound, mosquitoes, smoke, water When the door can still enter the room, the closing of the door gap is a problem that is not perfect.

To this end, this creation provides a magnetic sill, installed at all sides of the portal to cover the door gap to overcome the above problems.
