Description

A door and window sealing drainage structure

technical field

The utility model relates to the technical field of building doors and windows, in particular to a door and window sealing drainage structure.

Background technique

The door and window project is an important part of the building decoration project, and it is the external performance of the decoration quality. Its type, specification and material have a direct impact on the decoration effect. For a sliding door, since the door leaf slides along the track, when the two door leaves are closed, the vertical joint of the two door leaves and the seal between the door leaf lap joint and the lower track are the weak links of the door. When the pressure is high, it is easy to leak wind and rain.

Contents of the invention

The utility model aims to provide a door and window sealing and drainage structure aiming at the technical defects of the prior art, so as to solve the technical problem that the sliding door leaf has poor sealing performance and is difficult to effectively drain water after it is normally closed.

In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

A door and window sealing and drainage structure, including a fixed fan, a drainage seal, a fixed lower rail, an open lower rail, and splicing of the lower rail; the drainage sealing member includes a profile interface, a drainage channel, a one-way valve, and a rubber pad The two ends of the part have profile interfaces respectively, and there is a through drainage channel in the drainage sealing part, a one-way valve is set in the drainage channel, and a rubber pad is set on the top of the drainage sealing part; the drainage sealing part is located at the end of the fixed fan , the fixed lower rail and the opened lower rail are respectively docked with the profile interfaces on both sides of the drainage seal, and the outer sides of the fixed lower rail, the drainage seal, and the opened lower rail are fixedly connected with the lower rail.

As a preference, when the fixed fan is closed, the overlapping part of the fixed fan is tightly pressed against the rubber pad near the end of the track.

In the above technical solution, the door lower rail includes an open lower rail or a fixed lower rail connected by a waterproof seal, and a rubber pad, a one-way valve and a drainage channel are arranged on the waterproof seal. When the door is closed, the door leaf will move down, and the end of the door leaf lap near the track is tightly pressed together with the rubber pad to prevent water vapor from entering the room; the waterproof seal is equipped with a drainage channel and a one-way valve, when there is wind pressure outside When the wind pressure is lifted, the one-way valve is closed to prevent outdoor water vapor from entering the indoor track. When the wind pressure is relieved, the rainwater entering the indoor track from other places can be discharged outside through the one-way valve and the drainage channel. The lower rail is integrated by connecting the lower rail with the profiles of the end covers on both sides.

The utility model provides a door and window sealing drainage structure. The technical solution connects the two lower rails through the drainage seal. The drainage seal is designed with an elastic sealing block, a drainage channel and a one-way valve. The elastic sealing block seals the bottom of the fan and the lower rail. The one-way valve can prevent outdoor wind and rain from entering. Indoors, drainage channels can drain water that has entered the indoor track elsewhere. The utility model better seals the direct seal between the door leaf and the track through the drainage seal, prevents moisture from entering the room through the design of the drainage channel and the one-way valve, greatly improves the sealing and drainage performance of the door, and through the planning and design of the drainage channel , simplifies the processing technology of the lower track, and improves the production efficiency.
