The window frame mechanism 10 includes a frame 11 and two guide rails 12, and the two guide rails 12 are respectively disposed on two opposite sides of the frame 11 in the width direction along the length direction of the frame 11.

Specifically, the frame 11 is provided with two first windows arranged oppositely and a second window located between the two first windows along the length direction thereof, the window glass 30 includes a sliding glass 31 and two fixed glasses 32, the sliding glass 31 is slidably arranged on the two guide rails 12 and can cover the second window, so that the function of a sliding window can be realized. When the three-piece sliding window is produced, the frame body 11, the window glass 30 and the guide rail can be integrally formed by injection molding.

The two fixed glasses 32 are respectively disposed on two opposite sides of the frame 11 along the length direction thereof, specifically, respectively disposed in the two first windows, and the sliding glass 31 can slide between the two fixed glasses 32 along the two guide rails 12. The two fixing glasses 32 can be respectively embedded and sealed in the two first windows by gluing, so that the sealing performance and the assembling stability of the two fixing glasses 32 relative to the two first windows can be improved.
