the lower frame is a sectional material piece with the same section extending along the axial direction and is provided with an upper cavity with an upper opening and a lower cavity with a lower opening, a drain hole is communicated between the upper cavity and the lower cavity, and convex parts for installing and arranging a door leaf are symmetrically extended on the inner walls of two sides of the upper cavity;

and the doorsill cover plate covers the upper cavity, and sealing strips for abutting against and matching with the doorsill cover plate are respectively arranged on the inner walls of the two sides of the upper cavity so as to enable the upper cavity to form an isobaric cavity with the upper end sealed and the lower end opened.

In one implementation, the two side walls of the upper cavity body are divided into a first side wall and a second side wall, and the first side wall and the inner wall at the upper end of the second side wall are both provided with a C-shaped groove opening communicated with the upper cavity body for embedding the sealing strip, so that the sealing strip can be installed and detached and is arranged in the C-shaped groove opening.

In one implementation, the second height of the side wall is higher than the first height of the side wall.

In one implementation, the joint portion of the sealing strip for abutting against the door leaf is an inclined convex portion arranged in a downward inclination manner.

In one implementation, the sealing strip is a wool strip or a rubber strip.

In one implementation, the bottom surface of the upper cavity is a flow guide surface which is inclined downwards towards the direction of the water drainage hole.

To sum up, the utility model discloses for its beneficial effect of prior art is:

the utility model discloses simple structure, threshold apron and sealing strip combine the application to make the upper shed position of lower frame sealed, and then, make the upper cavity form the open isobaric cavity of the sealed lower extreme in upper end, increase when outer atmospheric pressure because sealing strip and threshold apron form sealed, the air leakage volume can let isobaric cavity atmospheric pressure increase rapidly in order to pass through the balanced internal and external pressure of wash port, and the ponding of isobaric intracavity can be discharged rapidly by the wash port, in order to reach high water tightness ability purpose.

Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 2, an embodiment of the present invention preferably provides a lower frame structure of an isobaric drainage sliding door, including: the door comprises a lower frame 1, a door leaf and a door leaf, wherein the lower frame 1 is a sectional material piece with the same cross section extending along the axial direction, and is provided with an upper cavity 2 with an upper opening and a lower cavity 3 with a lower opening, a drain hole 10 is communicated between the upper cavity 2 and the lower cavity 3, and convex parts 4 for installing the door leaf are symmetrically extended on the inner walls of two sides of the upper cavity 2; the doorsill cover plate 5 is arranged on the upper cavity 2 in a covering mode, sealing strips 6 for abutting and matching the doorsill cover plate 5 are arranged on the inner walls of the two sides of the upper cavity 2 respectively, so that the upper cavity 2 forms an equal-pressure cavity with an upper end sealed and a lower end opened, specifically, the two sealing strips 6 are sealed with the door fan in an annular double-way mode, the doorsill cover plate 5 is combined with the sealing strips 6 to be used, so that the upper opening position of the lower frame 1 is sealed, further, the upper cavity 2 forms an equal-pressure cavity with an upper end sealed and a lower end opened, when the external air pressure is increased, because the sealing strips 6 and the doorsill cover plate 5 form sealing, the air leakage amount can enable the air pressure of the equal-pressure cavity to be rapidly increased to balance the internal and external pressure through the drain hole 10, and accumulated water in the equal-pressure cavity can be rapidly discharged through the drain hole 10, so that the purpose of high water tightness can be achieved.
