The sliding window sash is installed inside the window frame, and the concealed screen assembly is also installed inside the window frame, facilitating its concealment and improving ease of use. The concealed screen assembly includes a screen box, a screen mesh, and a pull rod. The screen box is fixed inside the window frame, and the screen mesh is wound inside the screen box. The pull rod is connected to the outer end of the screen mesh, allowing the screen mesh to be pulled out from the screen box. The pull rod is detachably connected to the sliding window sash. By connecting the pull rod to the sliding window sash, the pull rod moves with the sliding window sash, thus opening the screen window simultaneously with opening the window, eliminating the need for further manual pulling of the screen window, improving its ease of use. Furthermore, the amount of screen mesh pulled out is consistent with the amount of sliding window sash movement, making the amount of pull rod movement variable, further enhancing the ease of use of the screen window.
[0004] In existing technology, the waterproofing at the connection between the window sash and the window frame is insufficient during the use of sliding windows. Water can easily seep in through the connection, causing dampness. Furthermore, it is not convenient to lock the window sash in the open position during the opening and closing of the sliding window. The window sash is easily shifted in position due to external forces or accidental contact, making it unstable. Therefore, improvements are needed. Utility Model Content

[0022] Please see Figure 1 , Figure 2 A protrusion 10 is fixedly connected to the outside of the plug 8. The protrusion 10 and the plug 8 are an integral structure. Both the protrusion 10 and the plug 8 are made of rubber. The protrusion 10 is designed so that it will deform when squeezed. The protrusion 10 is engaged with the window sash 3. The window sash 3 has a groove 11 inside. The protrusion 10 is engaged inside the groove 11. The protrusion 10 is engaged and fixed with the groove 11. A connecting strip 12 is fixedly connected to the left end of the plug 8. The connecting strip 12 contacts the window sash 3. Both the connecting strip 12 and the plug 8 are slidably connected to the slide rail 7. A locking mechanism 9 is provided on the window sash 3.
[0023] Please see Figure 1 , Figure 3 The locking mechanism 9 includes an arc-shaped groove 91. An arc-shaped groove 91 is formed inside the window frame 2. An arc-shaped block 92 is slidably fitted inside the arc-shaped groove 91. There are multiple arc-shaped grooves 91, evenly distributed inside the window frame 2. By designing multiple arc-shaped grooves 91, the arc-shaped block 92 can slide into different positions within the arc-shaped grooves 91. A slide block 97 is slidably fitted on the outer side of the arc-shaped block 92. The slide block 97 is fixedly connected to the window sash 3 and slidably connected to the window frame 2. A slider 93 is fixedly connected to the bottom of the arc-shaped block 92. The slider 93 is slidably connected to the slide block 97. A ball 94 is fixedly connected to the lower end of the slider 93. The ball 94 is fixedly connected to the slide block 97. A guide rod 95 is slidably sleeved inside the slider 93. The guide rod 95 is fixedly connected to the slide block 97.

Slider 93 will press ball 94, and slider 93 can move along guide rod. The sliding compression spring 96 can separate the arc block 92 from the arc groove 91. As the window sash 3 moves horizontally, the elastic action of the ball 94 and the spring 96 will give the slider 93 an upward counter-push force, which can push the arc block 92 into the arc groove 91 at another position. This can realize the insertion and cooperation of the arc block 92 with the arc groove 91 at different positions, which is convenient for adjusting the relative position of the window sash 3 and the window frame 2. It is also convenient for limiting the window sash 3 after it is opened, so as to avoid the impact of external forces on the stability of opening and closing.
