Door plate sealing mechanism

Abstract

The invention belongs to the technical field of a door, and particularly discloses a door plate sealing mechanism. An installing groove and a baffle plate groove are formed in the door plate; the baffle plate groove is positioned at the bottom of the door plate; a sealing element used for sealing a gap is arranged in the baffle plate groove; when the door is closed, the sealing element seals the gap; when the door is opened, the sealing element does not seal; a sealing unit used for controlling whether the sealing element extends out of the baffle plate groove or not is arranged in the installing groove; a triggering unit triggering the sealing unit to work is arranged on a hinge; when the door plate rotates, the triggering unit starts the sealing unit to work. Compared with the prior art, the door plate sealing mechanism has the advantages that the triggering unit starts the work of the sealing unit through the door plate rotation, so that the goal of sealing the gap by the sealing element is achieved; the condition that when the door plate is in a closed state, the sealing element completely seals the gap is ensured; cold air is prevented from entering a room; the heat insulation effect is achieved; meanwhile, after the gap is completely sealed, the sound is prevented from entering the room through passing through the door plate; the sound isolation effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of doors. Background technique [0002] At present, all doors used by people are of standard type. The door panels are installed on the door frame by hinges to form the door. After the door is installed, in order to facilitate the opening and closing of the door, and to avoid friction between the door and the ground during the opening and closing process, resulting in the door The door is completely damaged due to wear and tear, so there will be a gap between the door and the floor after the door is installed. [0003] Although this installation method solves the friction problem of opening and closing the door, the gap between the door and the bottom plate will cause the outside wind to enter the room from the gap, especially in winter, the cold air entering the room will cause the indoor temperature to drop rapidly, which is not good for the room The heat preservation effect is high, and the door panel does not ...

AI Technical Summary

Problems solved by technology

[0002] At present, the doors used by people are all standard types. The door panels are installed on the door frame by hinges to form a door. are subject to wear and eventually the door is completely damaged, so after the door is installed there is a gap between the underside of the door and the floor

[0003] Although this installation method solves the friction problem of opening and closing the door, due to the gap between the door and the bottom plate, the outside wind will enter the room from the gap, especially in winter, when the cold wind enters the room, the indoor temperature will drop rapidly, which is not conducive to the room temperature. Excellent thermal insulation effect, while the door panel does not have the effect of sound insulation and sealing
