However, this will cause a gap between the door leaf and the ground, which will affect the sealing performance of the door
In the prior art, some sealing strips or brush strips are provided at the bottom of the door. During the process of opening and closing the door, the sealing strips or brush strips will rub against the ground back and forth. In the long run, the sealing strips or brush strips are easily damaged. Affect the tightness
In the prior art, there are some doors with sealing strips on the side of the bottom. When the door is closed, the sealing strips abut against the side of the sill, so that the seal between the door and the sill is realized. However, this kind of solution must be provided with a sill. A door without a sill does not produce a sealing effect

The invention provides a sealing door, and relates to the technical field of doors and windows. The sealing door comprises a door frame and a door leaf. The door leaf is movably hinged to one verticalside of the door frame, and sealing strips used for abutting against the door frame are arranged on the left and right sides and the upper side of the door leaf. The sealing door further comprises abackstop mechanism and a filling and leveling-up mechanism, and the backstop mechanism comprises a backstop board capable of stretching and contracting up and down and a driving mechanism controllingthe backstop board to rise and fall; the filling and leveling-up mechanism comprises two air inflation bags correspondingly arranged on the two sides of the backstop board; a grove sunk downwards is formed in the end surface of the bottom of the door leaf, mounting grooves embedded in the ground are formed in the ground surfaces between the left and right side vertical frames of the door frame, and the backstop board and the two air inflation bags are correspondingly arranged in the mounting grooves; and when the driving mechanism drives the backstop board to extend upwards, the backstop boardis connected with the groove in a camping mode. The sealing door has a sealing effect and further has an anti-theft function.
Description
technical field [0001] The invention relates to the technical field of doors and windows, in particular to a hermetic door. Background technique [0002] Existing doors and windows, especially vertical hinged doors, always keep a certain distance between the bottom of the door leaf and the ground, so as to ensure that the opening and closing of the door are not hindered. However, this will cause a gap between the door leaf and the ground, which will affect the sealing performance of the door. In the prior art, some sealing strips or brush strips are provided at the bottom of the door. During the process of opening and closing the door, the sealing strips or brush strips will rub against the ground back and forth. In the long run, the sealing strips or brush strips are easily damaged. affect the tightness. In the prior art, there are also some doors with sealing strips on the side of the bottom. When the door is closed, the sealing strips abut against the side of the thresh...
