DETAILED DESCRIPTION

[0021] The utility model is described in detail according to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, the sealing structure for aluminum alloy doors and windows includes a rectangular frame 12 and a sliding window 19 plugged into the rectangular frame 12. The middle of the sliding window 19 is a transparent window 7, and the middle of the rectangular frame 12 is provided with a avoidance window corresponding to the transparent window 7.

[0023] An annular positioning frame 4 is provided on the inner edge of the rectangular frame 12. A positioning cavity for the sliding window 19 is formed between the annular positioning frame 4 and the rectangular frame 12. A sliding socket corresponding to the positioning cavity is provided on one side of the annular positioning frame 4. The sliding window 19 is inserted into the positioning cavity via the sliding socket. A damping guide mechanism, a reset mechanism, and a positioning member are provided between the sliding window 19 and the rectangular frame 12.

[0024] In this embodiment, the damping guide mechanism includes a cover plate 5 fixed to the outer end surface of the sliding window 19, an upper guide rod 2 and a lower guide rod 18 disposed parallel to each other at the upper and lower ends of the cover plate 5, and damping strips 3 disposed on the lower surface of the upper guide rod 2 and the upper surface of the lower guide rod 18. The damping strip 3 on the lower surface of the upper guide rod 2 is in close contact with the upper surface of the rectangular frame 12, and the damping strip 3 on the upper surface of the lower guide rod 18 is in close contact with the lower surface of the rectangular frame 12. The upper and lower surfaces of the rectangular frame 12 are respectively provided with dovetail-shaped guide grooves, and the lower portion of the damping strip 3 is dovetail-shaped to cooperate with the dovetail-shaped guide grooves. The reset mechanism includes an upper ear plate 8 and a lower ear plate 10 fixed to the rear side of the cover plate 5, an upper tension spring 9 connected between the upper ear plate 8 and the side wall of the rectangular frame 12, and a lower tension spring 11 connected between the lower ear plate 10 and the side wall of the rectangular frame 12. The positioning member is a positioning screw 1, which is screwed onto the upper guide rod 2 of the damping guide mechanism. The upper surface of the rectangular frame 12 is provided with a positioning hole corresponding to the positioning screw 1. The number of positioning holes is at least two, one for closed positioning and one for fully open positioning.

[0025] An annular cavity 20 is provided within the rectangular frame 12. An annular baffle 13 corresponding to the annular cavity 20 is provided on the outer side of the rectangular frame 12. Multiple springs 14 are evenly fixed to the inner surface of the annular baffle 13. A top block 15 is fixed to the top of each spring 14. The ends of each top block 15 are connected to a sealing ring 17. An annular groove corresponding to the sealing ring 17 is provided on the inner side of the rectangular frame 12. The bottom of the annular groove is provided with a through hole corresponding to each top block 15. The sealing ring 17 is tightly connected to the sidewall of the sliding window 19. An annular compression gasket 16 corresponding to the sliding window 19 is provided on the inner side of the annular positioning frame 4.

[0026] Working principle:

[0027] During use, the sealing ring 17 and the annular extrusion gasket 16 jointly clamp the sliding window 19 to achieve a sealing effect. The thrust of the spring 14 has a sealing compensation function. When the sealing ring 17 wears out after long-term use, the spring 14 still keeps the sealing ring 17 in close contact with the sliding window 19 through the top block 15, thereby extending the service life of the sealing structure. The cover plate 5 of the sliding window 19 is fixed with a handle 6. When in use, the handle 6 is used to push and pull the sliding window 19, which is simple and convenient to operate. To open the sliding window 19, the handle 6 is used to pull the sliding window 19 to the outermost side and position it with the positioning screw 1. Figure 4 .
