A drainage structure for glass doors and windows includes: a fixed frame 1; a supporting frame 2 is provided on the inner wall of one side of the fixed frame 1; an installation frame 3 is provided on the inner wall of one side of the supporting frame 2; a pull-out frame 4 is provided on the inner wall of one side of the supporting frame 2; translucent glass 5 is provided on the inner walls of both the installation frame 3 and the pull-out frame 4; a water collection groove 12 is provided on the inner wall of the bottom center of the fixed frame 1; several sloping channels 13 are provided on the inner wall of one side of the water collection groove 12; and water outlet holes are provided on the inner walls of the sloping channels 13. In hole 14, a telescopic storage device 18 is provided on the inner wall of the top side of the fixed frame 1. Several roller shutter baffles 19 are provided on the inner wall of the side of the telescopic storage device 18. Connectors 20 are provided on the inner walls of both ends of the roller shutter baffles 19. Sliding sliders 21 are provided on the inner walls of both ends of the roller shutter baffles 19. Limiting slide rails 22 are provided on the inner walls of both ends of the fixed frame 1. Locking parts 8 are provided on the inner walls of both ends of the fixed frame 1. A slope mounting plate 17 is provided on the inner wall of the top side of the water collection groove 12.
[0023] A fastening plug 25 is provided on the inner wall of the side end of the fixed frame 1. When the device is installed and used, it can improve the density of the device and prevent the device from becoming loose during use.
[0024] Each locking component 8 has a mounting hole 9 on its inner side wall. A mounting bolt 10 is installed inside the middle of the mounting hole 9. A limit washer 11 is installed on the bottom inner wall of the mounting bolt 10.
