AI Technical Summary
Existing side-pressure windows drain water slower than they enter during heavy rain, making it easy for rainwater to overflow the track's water barrier and enter the room, causing a failure in sealing.
Design a side-pressure window drainage structure, including a lower rail profile, a sliding table, a flat part and an inclined surface. An inclined surface is set between the sliding table and the flat part. Rainwater is guided to the drain outlet through the inclined surface and discharged. The inner side of the sliding table prevents rainwater from entering. A baffle and a drain outlet are provided on the flat part.
It enables rapid drainage of rainwater during heavy rain, preventing rainwater from entering the room and improving the window's sealing and drainage performance.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of side-pressure windows, and in particular to a drainage structure for a side-pressure window. Background Technology
[0002] Sliding windows are a common type of window, while side-press windows are based on sliding windows with the addition of a side-press function, making them more airtight. However, current side-press windows do not have a drainage structure and rely solely on their sealing performance to achieve a water-proof effect. Some side-press windows also use the drainage structure of sliding windows, which drains rainwater entering the track by opening a drainage outlet in the outdoor baffle. However, such a drainage structure is not perfect, especially in heavy rain. When the drainage speed is slower than the water inflow speed, the rainwater overflows the water-blocking edge of the track and enters the room before it reaches the drainage structure. Summary of the Invention
[0003] The present invention provides a drainage structure for a side-pressure window to solve the aforementioned problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for a side-pressure window, comprising a lower rail profile, wherein a sliding table for installing a movable sash is provided at the top of the lower rail profile and the end closer to the interior, and a flat portion is provided at the end closer to the exterior, wherein an inclined surface that gradually slopes downward is provided between the sliding table and the flat portion, and a baffle is provided at the exterior end of the flat portion, wherein a drainage outlet communicating with the exterior is provided at the bottom of the baffle.
[0005] Furthermore, the top of the slide table is provided with a slide bar and a sealing flange.
[0006] Furthermore, a support profile for mounting and fixing the fan is provided on the top of the flat portion.
[0007] Furthermore, the top of the support profile is provided with an opening.
[0008] Furthermore, a cover plate is provided above the supporting profile, and the cover plate is snap-fitted to the baffle and the supporting profile.
[0009] Compared with the prior art, the beneficial effects of this utility model are: the lower rail profile provides a drainage structure, which blocks the intrusion of rainwater on the indoor side by setting a raised sliding table. The rainwater that stays outside the movable fan flows down the inclined surface to the flat part and then is discharged from the drain outlet, thereby achieving rapid drainage of rainwater and preventing rainwater from overflowing the sliding table and entering the room.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] As attached Figure 1-4 As shown, the present invention discloses a drainage structure for a side-pressure window, comprising a lower rail profile 1. The top of the lower rail profile 1, near the interior end, is provided with a sliding table 11 for installing a movable fan 2. The interior end of the lower rail profile 1 is provided with a flat portion 12. An inclined surface 13 that gradually slopes downwards is provided between the sliding table 11 and the flat portion 12 to facilitate water flow. The exterior end of the flat portion 12 is provided with a baffle 14 that protrudes upwards. The bottom of the baffle 14 is provided with a drain outlet 140 that connects to the outside for draining accumulated water.
[0017] This utility model discloses a drainage structure for a side-pressure window, such as... Figure 2 The lower rail profile 1 provides a drainage structure. By setting a raised sliding platform 11, it blocks the intrusion of rainwater on the indoor side. When rainwater enters the area between the movable fan 2 and the fixed fan 3, the rainwater will not flow directly into the room due to the obstruction of the sliding platform 11. The rainwater flows along the inclined surface 13 to the flat part 12 and is finally discharged to the outside through the drain outlet 140 at the bottom of the baffle 14. The rainwater that stays outside the movable fan 2 flows along the inclined surface 13 to the flat part 12 and is discharged from the drain outlet 140, so as to quickly discharge the rainwater and prevent the rainwater from overflowing the sliding platform 11 and entering the room.
[0018] Specifically, the top of the slide table 11 is provided with a slide bar 111 and a sealing edge 112. The slide bar 111 is the existing guide rail. The bottom of the movable fan 2 is provided with a pulley, which slides on the slide bar 111. The sealing edge 112 can enhance the sealing between the movable fan 2 and the slide table 11 and reduce rainwater infiltration.
[0019] Specifically, the top of the flat part 12 is provided with a support profile 20 for installing the fixed fan 3. The support profile 20 is used to raise the fixed fan 3 to avoid the fixed fan 3 blocking the drainage. The top of the support profile 20 is provided with an opening 200. Rainwater enters the lower part from the opening 200 on the surface of the support profile 20 and flows from the lower part of the support profile 20 to the drain outlet 140.
[0020] Specifically, a cover plate 202 is provided above the supporting profile 20. The cover plate 202 is snapped to the baffle 14 and the supporting profile 20. The fixed fan 3 is provided on one side of the window, that is, one side of the length direction of the flat part 12, while the other side of the flat part 12 is covered by the cover plate 202 to prevent debris from entering, and at the same time, the surface is more beautiful.
[0021] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
