The lower track 1 includes a first mounting groove 20 and a second mounting groove 30. As shown, the first mounting groove 20 and the second mounting groove 30 are arranged side by side, with the first mounting groove 20 located indoors and the second mounting groove 30 located outdoors. A pulley assembly 22 is provided at the bottom of the first sash 2, and the pulley assembly 22 is slidably disposed within the first mounting groove 20, i.e., the first sash 2 is an openable sash. An integrally formed cover plate 100 is provided at the top of the second mounting groove 30. The top of the 00 has a connecting block 1001, which is fixedly connected to the second fan body 3 through the connecting block 1001. That is, the second fan body 3 is a fixed fan. It should be noted that the pulley assembly 22 includes a connector installed on the profile of the first fan body 2 and a pulley set at the bottom of the connector. The connector and the connecting block 1001 on the cover plate 100 have corresponding shapes. The first mounting groove 20 and the second mounting groove 30 are interconnected. The outdoor side of the second mounting groove 30 is provided with a drain outlet 301 so that the rainwater entering the first mounting groove 20 can be guided to the second mounting groove 30 and discharged outdoors through the drain outlet 301. The second mounting groove 30 temporarily stores rainwater to prevent backflow, and drains the rainwater through the drain outlet 301. At the same time, a cover plate 100 is provided on the top of the second mounting groove 30. The cover plate 100 has a connecting block 1001 for installing the second door sash 3, so that the second mounting groove 30 has the functions of storing rainwater and installing door and window sashes. There is no need to set up a water storage tank, which effectively reduces the width of the lower rail 1 profile and makes the overall design more coordinated and beautiful.

[0018] Specifically, a stepped structure 221 is provided in the first mounting groove 20. The stepped structure 221 is provided with a guide rail 222 for sliding the pulley assembly 22. The stepped structure 221 slopes downward from indoors to outdoors. An overlapping platform is provided at the bottom of the mounting groove for installing the stepped structure 221. The outdoor end of the stepped structure 221 corresponds to the height of the overlapping platform.

[0019] refer to Figure 1 and 3 The a cover plate 100 is disposed on the top of the second mounting groove 30 and protrudes to the top of the first mounting groove 20 on one side. A b cover plate 200 is disposed on one side of the top of the first mounting groove 20. A gap is formed between the b cover plate 200 and the a cover plate 100. This gap is used for the pulley assembly 22 to pass through and be disposed in the first mounting groove 20.

[0020] Specifically, a cover plate 300 (c) is provided on the top of the second mounting groove 30, and the length of cover plate 100 (a) corresponds to the length of the second fan body 3. The sum of the lengths of cover plate 300 (c) and cover plate 100 (a) is equal to the length of the lower rail 1. Cover plate 300 (c) and cover plate 100 (a) are arranged side by side. Cover plate 300 (c) has drainage holes 3003 communicating with the second mounting groove 30. Since the second fan body 3 is a fixed fan, it will only occupy one side of the lower rail 1 along its length, while the other side is for people to enter and exit. The inlet and outlet are provided with a cover plate 300 on the other side of the second mounting groove 30. When rainwater near the second mounting groove 30 is exposed to the outside, it must first pass through the cover plate 300 before entering the gap. Most of the rainwater will enter the second mounting groove 30 through the drainage holes 3003 of the cover plate 300, thereby reducing the amount of rainwater entering the first mounting groove 20 and reducing the drainage pressure of the first mounting groove 20. Alternatively, a cover plate 100 can be installed separately on the second mounting groove 30. The length of the cover plate 100 is equal to the length of the lower rail 1.

[0021] Specifically, the first mounting groove 20 and the second mounting groove 30 have the same structure and are symmetrically arranged. A thermal break adhesive 40 is provided between the first mounting groove 20 and the second mounting groove 30. The thermal break adhesive 40 belongs to the existing thermal break aluminum window and door structure. It should be noted that the first mounting groove 20 and the second mounting groove 30 have the same structure and are symmetrically arranged with the thermal break adhesive 40 as the midpoint. The thermal break adhesive 40 connects to the lower part of the opposite surface of the first mounting groove 20 and the second mounting groove 30, thereby forming a passageway groove on the thermal break adhesive 40. Since the cover plate 100 extends and protrudes to the top of the first mounting groove 20, that is, the cover plate 100 is located at... The top of the passageway is covered by a cover plate 100, which shields the second mounting groove 30 and the passageway. A connecting hole 234 is provided on the side of the first mounting groove 20 and the second mounting groove 30 that is close to each other to ensure that the rainwater flows out unobstructed. In addition, it can also be installed in reverse. For example, the positions of cover plate 100 and cover plate 200 can be swapped, with cover plate 100 placed on the first mounting groove 20 and cover plate 200 placed on the second mounting groove 30. The second fan body 3 is installed on the top of the first mounting groove 20. A guide rail 222 is installed in the second mounting groove 30, and the first fan body 2 is slidably installed in the second mounting groove 30, which can be used flexibly.
