[0027] like Figure 1As shown, in Example 1, a high-insulation and high-airtightness sliding window structure comprises a sliding fan and a lower track, and a heat preservation block 5 is arranged on the sliding fan. Preferably, the heat preservation block 5 is a heat preservation cotton block. The lower part of the sliding fan is provided with a fan overlap rubber strip 4 that matches the lower track, and the lower part of the sliding fan is slidably arranged on the lower track, and a heat preservation lining strip is arranged on the lower track, and a sealing rubber strip 3 that matches the sliding fan is arranged on the upper part of the heat preservation lining strip. The structure is simple, the sliding fan and the lower track are slidably matched, and the sliding fan realizes four-way sealing through the fan overlap rubber strip 4 and the sealing rubber strip 3, and the sealing effect is good. The heat preservation lining strip is arranged on the lower track and the heat preservation block 5 is arranged on the sliding fan. The two cooperations further improve the heat preservation effect of the sliding fan profile, and solve the problems of poor air tightness, poor thermal performance and high energy consumption when the sliding window is closed in the prior art.

[0028] like Figure 1 As shown, embodiment 2 is a high-insulation and high-airtightness sliding window structure, wherein the sliding sash comprises an outer sash profile 9 and an inner sash profile 6, a sash heat insulation strip is connected between the outer sash profile 9 and the inner sash profile 6, glass is installed on the upper part of the inner sash profile 6 and the outer sash profile 9, and an adjustable pressure line 7 for fixing the glass is installed on the upper part of the inner sash profile 6. The adjustable pressure line 7 is installed at the upper notch of the inner sash profile 6, and the gap between the adjustable pressure line 7 and the glass and the gap between the upper notch of the outer sash profile 9 and the glass are sealed. The sealing strip 3 can be selected or glued. The adjustable pressure line 7 can be set to different levels of width according to the thickness of the glass. The gap between the adjustable pressure line 7 and the glass and the gap between the upper notch of the outer sash profile and the glass are set to 3~5mm, so that the sealing treatment of the glass is tighter, and the airtightness between the glass and the sliding sash is improved. The fan outer profile 9 and the fan inner profile 6 are connected through a fan insulation strip, and the fan insulation strip is two sealing strips 3 arranged parallel to each other up and down. The cavity between the two sealing strips 3 and between the fan outer profile 9 and the fan inner profile 6 are filled with polyurethane foam. The polyurethane foam has the performance of thermal insulation, which reduces the heat exchange between the indoor and outdoor of the sliding fan, and further improves the thermal insulation performance of the sliding window. An adjustable strip that cooperates with the glass is provided on the fan inner profile 6 to facilitate the replacement of the glass, thereby improving the convenience of replacing the sliding fan.

[0029] In this embodiment, the lower parts of the fan outer profile 9 and the fan inner profile 6 are both provided with a C-shaped slot 6-1 that cooperates with the fan overlap rubber strip 4. The C-shaped slots 6-1 of the fan outer profile 9 and the fan inner profile 6 are symmetrically arranged and both face the track side wall of the downward sliding track, so as to facilitate the dynamic sealing cooperation between the fan overlap rubber strip and the track side wall. The sealing rubber strip 3 and the fan overlap rubber strip 4 are both EPDM rubber strips, which have good elasticity and resistance to compression deformation. The surface of the rubber strip is treated with friction resistance and is durable. The deformation of the sealing rubber strip 3 and the fan overlap rubber strip 4 is 3~5mm.

The frame heat insulation strip 12 is arranged between the inner rail profile 1 and the outer rail profile 11, which increases the heat preservation of the lower slide track. The frame heat insulation strip 12 is two heat insulation strips arranged in parallel, and the cavity between the frame heat insulation strip 12 and the inner rail profile 1 and the outer rail profile 11 is filled with a polyurethane foam part, and the cavity on the inner rail profile 1 and the outer rail profile 11 is filled with a polyurethane foam part, which further improves the heat preservation and heat insulation performance of the lower slide track profile.

[0033] In this embodiment, the thermal insulation lining strip includes an inner rail lining strip 2 and a lower concave lining strip 10. The inner rail lining strip 2 is clamped in the track portion of the inner rail profile 1, and the lower concave lining strip 10 is clamped between the track portion of the inner rail profile 1 and the track portion of the outer rail profile 11, and the lower concave lining strip 10 is located above the frame thermal insulation strip 12. The inner rail lining strip 2 is an L-shaped lining strip, which is clamped in the L-shaped track plate, and one side of the L-shaped lining strip fits the support plate. The inside of the L-shaped lining strip and the inside of the lower concave lining strip 10 are filled with polyurethane foam parts to further improve the thermal insulation performance. The lower concave lining strip 10 is a concave structure, and the two sides of the lower concave lining strip 10 are respectively fitted with the corresponding support plate on the inner rail profile 1 and the support plate on the outer rail profile 11, and the top of the lower concave lining strip 10 is flush with the L-shaped track plate as the upper track end face of the lower track. The lower part of the sliding fan is an inverted concave structure that cooperates with the L-shaped track plate and the downward concave lining strip 10, which is convenient for limiting the sliding of the sliding fan. The thermal insulation cotton block is arranged in the concave structure, and the connection between the excessive insulation strip and the downward track further ensures the thermal insulation performance of the sliding window.

[0034] In this embodiment, both the inner rail lining strip 2 and the lower concave lining strip 10 are provided with a rubber strip groove, and a sealing rubber strip 3 is installed in the rubber strip groove.
