Detailed Description

In order to clearly illustrate the technical characteristics of the scheme, the scheme is explained below through a specific embodiment.

The door device with the upper and lower sealing functions as shown in fig. 1, comprises a door body 1, wherein the top and the bottom of the door body 1 are respectively provided with a movable wheel, the movable wheel above is used for preventing the door body from tilting and guiding, and the movable wheel below is used for supporting the door body and reducing the movement resistance of the door body. The top and the bottom of the door body are respectively provided with a sealing air bag 2, and the sealing air bag 2 is positioned at one side of the movable wheel in the thickness direction of the door body so as to avoid interference with the movable wheel when the sealing air bag moves. The length of the sealing air bag is consistent with that of the door body, and a pushing mechanism 3 for driving the sealing air bag to vertically move is arranged on the inner side of the door body.

The pushing mechanism 3 comprises an adjusting gear rotatably connected with the door body through a transverse shaft 32, and two vertical racks 31 meshed with the adjusting gear and respectively positioned on two sides of the adjusting gear, wherein one end of the adjusting gear, which is far away from the door body, is coaxially and fixedly connected with a rotating handle 321, and when the rotating handle 321 is rotated, the adjusting gear rotates along with the rotating handle, and the two vertical racks are driven to respectively move upwards and downwards by utilizing the meshing effect when the adjusting gear rotates, so that the upper sealing air bag and the lower sealing air bag are pushed. The upper end of one vertical rack 31 is connected with an upper push plate 21 positioned at the upper side of the door body, the upper push plate 21 is connected with the door body 1 through windproof cloth 4, a sealing air bag at the top of the door body is fixedly connected to the upper surface of the upper push plate, the lower end of the other vertical rack 31 is connected with a lower push plate positioned at the lower side of the door body, the lower push plate is connected with the door body through windproof cloth, and the sealing air bag at the bottom of the door body is fixedly connected to the lower surface of the lower push plate. In this embodiment, the lengths of the upper push plate and the lower push plate are consistent with the length of the sealing air bag, and the windproof cloth is foldable flexible cloth, so that the obstruction to the movement of the upper push plate and the lower push plate is avoided.

In order to ensure the shielding effect of the sealing airbag in the whole length direction, the pushing mechanisms of the embodiment are two groups, and the two pushing mechanisms are transversely distributed and respectively close to two ends of the door body in the length direction.

In order to improve the stability of the movement of the vertical rack, in this embodiment, a guide chute extending vertically is provided on the side surface of the vertical rack facing the door body, and a guide rail 311 adapted to the guide chute is fixedly provided on the door body. The guide rail 311 is located one side of the guide chute and has set firmly T type platform, the guide chute is T type groove, avoids vertical rack slope better. The door body is internally provided with a mounting groove 11 for mounting the guide rail and the rack.

In the use process, when the door body is required to be closed, the upper push plate and the lower push plate are positioned at the contact position of the door body, after the door body is closed, the rotary handle is rotated, and the vertical racks respectively and correspondingly move upwards and downwards at the same time, so that the sealing air bag at the top of the door body is contacted with the upper door frame, the sealing air bag at the bottom of the door body is contacted with the lower door frame, the windproof cloth is correspondingly unfolded at the same time, and a gap between the upper push plate and the door body and a gap between the lower push plate and the door body are blocked, thereby blocking the gaps at the upper side and the lower side of the door body and avoiding direct blowing of external wind; when the door body needs to be opened, the rotary handle is reversely rotated, so that the upper sealing air bag and the lower sealing air bag leave the door frame, and the movement of the door body is prevented from being hindered. Because in practice, the length of the door body is generally greater than the width of the door opening, after the door body is closed, an overlapped part exists between the left side edge and the right side edge of the door body and the side edge of the door frame, and external wind cannot be caused to directly blow the interior of the building, so that the sealing of the two sides of the door body does not belong to the problem to be solved by the scheme.
