Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a heat preservation structure at a hook position of a sliding door and window, and a sliding door and window comprising the heat preservation structure at the hook position of the sliding door and window. Background Art

[0002] Sliding doors and windows usually include a fixed outer frame and at least two door and window sashes that are movably mounted on the outer frame. Each door and window sash includes a sash frame and a sash panel mounted in the sash frame. The sash panel is usually made of glass. The opening and closing of the sliding doors and windows are achieved by moving the door and window sashes. Each door and window sash is also provided with a hook. When the sliding doors and windows are in a closed state, the hooks of the two adjacent door and window sashes are staggered, and the hooks of the two adjacent door and window sashes constitute the hook portion of the sliding doors and windows.

[0003] In recent years, due to the impact of policies related to reducing CO2 emissions, high-insulation door and window products are needed. In sliding doors and windows, the hook and bevel part is the part with the largest heat flow loss, that is, the insulation effect (or heat insulation capacity) of the hook and bevel part is the biggest shortcoming of sliding doors and windows.

[0004] In the prior art, the heat preservation method at the hook part of sliding doors and windows is: the sash profile at the hook part of the door and window is set as a thermal break profile, and the thermal break profile includes an aluminum alloy profile body and a PA66 heat insulation strip fixedly embedded in the aluminum alloy profile body; for example, a sliding window heat insulation cover plate disclosed in the Chinese utility model patent with the authorization announcement number CN208734246U. This existing heat preservation method has the following defects:

[0005] 1. The heat insulation technical measures are single, and heat insulation is achieved only by the heat insulation strips inside the broken bridge profile. Its ability to prevent heat from transferring from indoors to outdoors is poor, resulting in weak heat insulation capacity at the hook part, which ultimately makes it difficult to improve the overall thermal insulation effect of sliding doors and windows.

[0006] 2. Since the thermal insulation technology is only realized by the thermal insulation profile, the distance between the indoor side fan profile and the outdoor side fan profile at the hook position of the sliding door and window is very small, and the two are very close in the indoor and outdoor directions. The heat flow loss is fast, and the thermal insulation ability is weak, which easily leads to the low temperature of the indoor side fan profile at the hook position, which is easy to condense. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a heat preservation structure at the hook portion of a sliding door and window, which effectively improves the heat insulation capacity at the hook portion.

[0008] To achieve the above-mentioned purpose, the utility model provides a heat preservation structure at the hook part of a sliding door and window, comprising an inner hook arranged on an indoor door and window leaf, and an outer hook arranged on an outdoor door and window leaf, the inner hook comprising an indoor hook leaf profile of the indoor door and window leaf, and an inner thermal insulation cover plate installed on the outdoor end surface of the indoor hook leaf profile, the inner thermal insulation cover plate being provided with a first hook portion; the outer hook comprises an outdoor hook leaf profile of the outdoor door and window leaf, and an outer thermal insulation cover plate installed on the indoor end surface of the outdoor hook leaf profile, the outdoor hook leaf profile or the outer thermal insulation cover plate being provided with a second hook portion;

[0009] Among the indoor hook-and-slide fan profile and the outdoor hook-and-slide fan profile, at least the indoor hook-and-slide fan profile is a thermal break profile;

[0010] When the indoor door and window sash and the outdoor door and window sash are opened, the first hook portion and the second hook portion are separated;

[0011] When the indoor door and window leafs and the outdoor door and window leafs are closed, the first hook portion is distributed on the outdoor side of the second hook portion, and the two are at least partially opposite in the indoor and outdoor directions, and the indoor hook-sash profile, inner thermal insulation cover plate, outer thermal insulation cover plate and outdoor hook-sash profile are distributed in sequence from indoor to outdoor.

[0012] In the thermal insulation structure at the hook part of the sliding door and window involved in the present application, when the sliding door and window are closed, the hook part of the sliding door and window is insulated in the indoor and outdoor directions through the indoor side broken bridge profile (i.e. the indoor side hook fan profile), the inner thermal insulation cover plate, the outer thermal insulation cover plate and the outdoor side hook fan profile, so as to prevent heat from being transferred from the indoor to the outdoor. The thermal insulation structure of the present application is a multiple thermal insulation structure in the indoor and outdoor directions, and the thermal insulation measures are at least a broken bridge profile and two inner and outer thermal insulation cover plates. The multiple thermal insulation structure has the following advantages: 1.

The inner thermal insulation cover plate and the outer thermal insulation cover plate are distributed between the indoor side hook fan profile and the outdoor side hook fan profile. While improving the thermal insulation capacity, it can also increase the distance between the indoor side hook fan profile and the outdoor side hook fan profile in the indoor and outdoor directions. , combined with the slow heat flow loss, the indoor side hook and hinged fan profile is not easy to condense, thereby improving the product performance of sliding doors and windows; 3. After the thermal insulation capacity of the hook and hinged part is improved, the thermal insulation coefficient of the entire sliding door and window is effectively reduced, and the use area of ​​sliding doors and windows in the north is expanded; 4. After the thermal insulation capacity of the hook and hinged part is improved, the energy-saving effect of the entire sliding door and window is effectively improved, and the size and area of ​​the entire sliding door and window can be expanded under the condition of certain energy consumption, thereby expanding the indoor field of view and lighting; 5. The inner and outer thermal insulation cover plates are distributed between the indoor side hook and hinged fan profiles and the outdoor side hook and hinged fan profiles, and are not exposed on the outer surface of the sliding doors and windows, thereby reliably ensuring the appearance of the sliding doors and windows.

The first inner cover transverse section and the second inner cover transverse section can effectively cover the indoor side hook and tilt sash profile in the width direction of the indoor side door and window sash, and reliably ensure the heat insulation effect.

[0014] Furthermore, the interlocking structure of the indoor hook-and-slide profile and the inner thermal insulation cover plate is preferably: the indoor end of the inner cover longitudinal section is provided with a first interlocking protrusion, and the profile auxiliary material is provided with a first interlocking groove for accommodating the first interlocking protrusion; the end of the second inner cover transverse section away from the inner cover longitudinal section is provided with a second interlocking protrusion and a second interlocking groove, and the second connecting portion is provided with a third interlocking groove for accommodating the second interlocking protrusion, and a third interlocking protrusion for accommodating the second interlocking groove; there is a first movable gap between the first interlocking protrusion and the groove wall of the first interlocking groove, between the second interlocking protrusion and the groove wall of the third interlocking groove, and between the third interlocking protrusion and the groove wall of the second interlocking groove, and the first movable gap enables the inner thermal insulation cover plate to be movably interlocked with the profile main material and the profile auxiliary material. The movable interlocking structure of the inner thermal insulation cover plate allows the inner thermal insulation cover plate to expand and contract well under different heating temperatures during the thermal insulation process, thereby better improving the thermal insulation capacity of the hook-and-slide part of the sliding door and window.

[0015] Furthermore, the second inner cover transverse section is an inner and outer double-layer structure in the indoor and outdoor directions, so that a cover plate cavity is formed in the second inner cover transverse section, which better improves the heat insulation capacity at the hook part of the sliding door and window.

[0016] Further, the structure of the outdoor hook-and-slide fan profile and the external heat-insulating cover plate is preferably as follows: the indoor side of the outdoor hook-and-slide fan profile is provided with a third connection portion, and the third connection portion is arranged near the outer edge of the outdoor door and window sash along the width direction of the outdoor door and window sash; the external heat-insulating cover plate includes an outer cover longitudinal section extending straightly along the indoor and outdoor directions, a first outer cover transverse section extending from the outer cover longitudinal section away from the third connection portion along the width direction of the outdoor door and window sash, and a second outer cover transverse section extending from the outer cover longitudinal section toward the third connection portion along the width direction of the outdoor door and window sash, the outer cover longitudinal section and the outdoor hook-and-slide fan profile, as well as the second outer cover transverse section and the third connection portion are all engaged and fixed, the second hook portion extends from the indoor side end of the third connection portion toward the direction close to the first outer cover transverse section, and the second hook portion is distributed on the indoor side of the second outer cover transverse section. The first outer cover transverse section and the second outer cover transverse section can effectively cover the outdoor hook-and-slide fan profile in the width direction of the outdoor door and window sash, and reliably ensure the heat insulation effect.

[0017] Furthermore, the interlocking structure of the outdoor hook-and-swing fan profile and the external thermal insulation cover plate is preferably: the outdoor end of the external cover longitudinal section is provided with a fourth interlocking protrusion, and the outdoor hook-and-swing fan profile is provided with a fourth interlocking groove for accommodating the fourth interlocking protrusion; the end of the second external cover transverse section away from the external cover longitudinal section is provided with a fifth interlocking protrusion, and the third connecting portion is provided with a fifth interlocking groove for accommodating the fifth interlocking protrusion; there is a second movable gap between the fourth interlocking protrusion and the groove wall of the fourth interlocking groove, and between the fifth interlocking protrusion and the groove wall of the fifth interlocking groove, and the second movable gap enables the external thermal insulation cover plate to be movably interlocked with the outdoor hook-and-swing fan profile. The movable interlocking structure of the external thermal insulation cover plate allows the external thermal insulation cover plate to expand and contract well under different heating temperatures during the thermal insulation process, thereby better improving the thermal insulation capacity of the hook-and-swing part of the sliding door and window.

[0018] Furthermore, the heat preservation structure at the sliding door and window hook position also includes a first sealing strip fixed to the outer side of the inner hook, and a second sealing strip fixed to the inner side of the outer hook, the first sealing strip is arranged along the width direction of the indoor door and window leaf close to the outer edge of the indoor door and window leaf, and the second sealing strip is arranged along the width direction of the outdoor door and window leaf close to the outer edge of the outdoor door and window leaf; when the indoor door and window leaf and the outdoor door and window leaf are closed, the first sealing strip abuts against the outer hook, and the second sealing strip abuts against the inner hook. By adding two sealing strips between the inner hook and the outer hook, the flow of hot and cold air between indoor and outdoor is effectively prevented.

[0019] Furthermore, the inner and outer thermal insulation cover plates are both resin profiles, and the material of the resin profiles is hard PVC. The inner and outer thermal insulation cover plates of the resin profile can effectively inhibit heat conduction and better improve the thermal insulation capacity of the hook part of the sliding door and window.

[0020] Furthermore, the preferred structure of the indoor hook-and-slide sash profile is as follows: the indoor hook-and-slide sash profile includes a main profile, an auxiliary profile, and a first insulation strip and a second insulation strip that are perpendicular to each other; the main profile has a first connection portion distributed on the indoor side of the auxiliary profile, and a second connection portion distributed on the outer side of the auxiliary profile along the width direction of the indoor door and window sash; the first insulation strip is fixedly arranged between the first connection portion and the auxiliary profile along the thickness direction of the indoor door and window sash; the second insulation strip is fixedly arranged between the second connection portion and the auxiliary profile along the width direction of the indoor door and window sash; and the inner thermal insulation cover plate is installed on the second connection portion and the auxiliary profile. The thermally insulated bridge profile constituting the indoor hook-and-slide sash profile adopts a 90° insulation strip through-strip structure to improve the thermal insulation effect, thereby better improving the thermal insulation capacity at the hook and slide position of the sliding door and window.

[0021] Furthermore, a thermal insulation cavity is formed between the main profile material and the auxiliary profile material of the thermal insulation profile, and the thermal insulation profile is provided with a thermal insulation foam material in the thermal insulation cavity, thereby better improving the heat insulation capacity at the hook portion of the sliding door and window.

[0022] Furthermore, the indoor hook-and-slope fan profile is a thermally-broken aluminum profile, and the outdoor hook-and-slope fan profile is an ordinary aluminum profile. The indoor thermally-broken aluminum profile, the inner thermally-broken cover plate, and the outer thermally-broken cover plate can already well achieve thermal insulation of the hook-and-slope part, that is, the heat transfer coefficient obtained by the multiple thermally-broken structure composed of the indoor thermally-broken aluminum profile, the inner thermally-broken cover plate, the outer thermally-broken cover plate, and the ordinary aluminum profile on the outdoor side is very close to the heat transfer coefficient obtained by the multiple thermally-broken structure composed of the indoor thermally-broken aluminum profile, the inner thermally-broken cover plate, the outer thermally-broken cover plate, and the outdoor thermally-broken aluminum profile. In this way, the present application only sets the indoor hook-and-slope fan profile as a thermally-broken aluminum profile, which can reduce costs while ensuring the thermal insulation effect.

[0025] The indoor side door and window sash also includes an indoor side sash profile arranged opposite to the indoor side hook and tilt sash profile along the width direction thereof, and a first sash panel installed between the indoor side hook and tilt sash profile and the indoor side sash profile, wherein the indoor side sash profile is a broken bridge profile and has two fourth heat insulation strips arranged side by side along the width direction of the indoor side door and window sash;

[0026] The outdoor door and window sash further comprises an outdoor sash profile arranged opposite to the outdoor hook and tilt sash profile along its width direction, and a second sash panel installed between the outdoor hook and tilt sash profile and the outdoor sash profile, wherein the outdoor sash profile is a broken bridge profile and has two fifth heat insulation strips arranged side by side along the width direction of the outdoor door and window sash;

[0027] Thermal insulation foam material is arranged on the outer periphery of the first fan panel, the outer periphery of the second fan panel, between two third thermal insulation strips, between two fourth thermal insulation strips, and between two fifth thermal insulation strips;

[0028] When the indoor door and window sashes and the outdoor door and window sashes are closed, the peripheral area of ​​the third insulation strip in the first vertical frame is connected to the peripheral area of ​​the fourth insulation strip, and the peripheral area of ​​the third insulation strip in the second vertical frame is connected to the peripheral area of ​​the fifth insulation strip.

[0029] The sliding door and window with the above structure can realize the continuity of the heat-breaking line, greatly reduce the heat flow loss, and reliably ensure the thermal insulation coefficient of the whole window.

[0030] As described above, the heat preservation structure at the hook portion of the sliding door and window and the sliding door and window involved in the utility model have the following beneficial effects:

[0031] When the sliding doors and windows are closed, the hook-shaped parts of the sliding doors and windows are insulated in the indoor and outdoor directions through the indoor side thermal insulation profile, the inner thermal insulation cover plate, the outer thermal insulation cover plate and the outdoor side thermal insulation fan profile, thereby preventing heat from being transferred from the indoor to the outdoor. The thermal insulation structure of the present application is a multiple thermal insulation structure in the indoor and outdoor directions, and the thermal insulation measures are at least a thermal insulation profile and two layers of thermal insulation cover plates inside and outside. The multiple thermal insulation structure has the following advantages: 1. It effectively reduces the heat flow loss at the hook-shaped parts and greatly improves the thermal insulation capacity of the hook-shaped parts, which is conducive to the implementation of energy-saving and environmental protection policies, meets the high requirements of strict energy conservation in the construction industry, and enhances the product competitiveness of sliding doors and windows; 2. The inner thermal insulation cover plate and the outer thermal insulation cover plate are distributed between the indoor side thermal insulation fan profile and the outdoor side thermal insulation fan profile. While improving the thermal insulation capacity, it can also increase the distance between the indoor side thermal insulation fan profile and the outdoor side thermal insulation fan profile in the indoor and outdoor directions. , combined with the slow heat flow loss, the indoor side hook and hinged fan profile is not easy to condense, thereby improving the product performance of sliding doors and windows; 3. After the thermal insulation capacity of the hook and hinged part is improved, the thermal insulation coefficient of the entire sliding door and window is effectively reduced, and the use area of ​​sliding doors and windows in the north is expanded; 4. After the thermal insulation capacity of the hook and hinged part is improved, the energy-saving effect of the entire sliding door and window is effectively improved, and the size and area of ​​the entire sliding door and window can be expanded under the condition of certain energy consumption, thereby expanding the indoor field of view and lighting; 5.

Among the indoor hook-and-slide fan profile 30 and the outdoor hook-and-slide fan profile 50, at least the indoor hook-and-slide fan profile 30 is a thermal break profile, and the outdoor hook-and-slide fan profile 50 can be a thermal break profile or a common profile; the thermal break profile refers to a profile with a heat insulation strip fixed inside.

[0111] When the indoor door and window sash 10 and the outdoor door and window sash 20 are opened, that is, the sliding door and window are opened, the first hook portion 41 and the second hook portion 51 are separated, and the first hook portion 41 is distributed on the left side of the second hook portion 51. When the indoor door and window sash 10 and the outdoor door and window sash 20 are closed, that is, the sliding door and window are closed, as shown in FIG. Figure 3 and Figure 4 As shown, the first hook portion 41 is distributed on the outdoor side (i.e., the front side) of the second hook portion 51, and the first hook portion 41 and the second hook portion 51 are at least partially opposite to each other in the indoor and outdoor directions, but the first hook portion 41 and the second hook portion 51 do not touch each other, so as to facilitate the opening of the indoor door and window sash 10 and the outdoor door and window sash 20. At the same time, when the indoor door and window sash 10 and the outdoor door and window sash 20 are closed, the inner hook 11 and the outer hook 21 are opposite to each other in the front-to-back direction, that is, the indoor hook sash profile 30, the inner thermal insulation cover plate 40, the outer thermal insulation cover plate 60 and the outdoor hook sash profile 50 are opposite to each other in sequence from back to front along the direction from indoor to outdoor. In this way, at the hook part of the sliding door and window, the heat on the indoor side must pass through the indoor hook fan profile 30, the inner thermal insulation cover plate 40, the outer thermal insulation cover plate 60 and the outdoor hook fan profile 50 in sequence before it can flow to the outdoors. Among the indoor hook fan profile 30, the inner thermal insulation cover plate 40, the outer thermal insulation cover plate 60 and the outdoor hook fan profile 50, at least the indoor hook fan profile 30, the inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 all play the role of heat insulation and heat insulation, effectively preventing heat from being transferred from indoors to outdoors, thereby achieving heat preservation at the hook part of the sliding door and window.

[0112] Obviously, the insulation structure at the hook part of the sliding door and window involved in the present application is a multiple thermal insulation structure in the indoor and outdoor directions, and the thermal insulation measures are at least a thermal insulation profile and an inner and outer double thermal insulation cover plate. The multiple thermal insulation structure has the following advantages: 1. It effectively reduces the heat flow loss at the hook part and greatly improves the thermal insulation capacity of the hook part, which is conducive to the implementation of energy-saving and environmental protection policies, meets the high requirements of strict energy conservation in the construction industry, and enhances the product competitiveness of sliding doors and windows; 2. The inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 are distributed between the indoor hook fan profile 30 and the outdoor hook fan profile 50. While improving the thermal insulation capacity, it can also increase the space between the indoor hook fan profile 30 and the outdoor hook fan profile 50. The spacing in the indoor and outdoor directions, combined with the slow heat loss, makes it difficult for the indoor side hook and tilt fan profile 30 to condense, thereby improving the product performance of sliding doors and windows; 3. After the thermal insulation capacity of the hook and tilt part is improved, the thermal insulation coefficient of the entire sliding door and window is effectively reduced, and the use area of ​​​​sliding doors and windows in the north is expanded; 4. After the thermal insulation capacity of the hook and tilt part is improved, the energy-saving effect of the entire sliding door and window is effectively improved, and the size and area of ​​the entire sliding door and window can be expanded under the condition of certain energy consumption, thereby expanding the indoor field of view and lighting; 5. The inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 are distributed between the indoor side hook and tilt fan profile 30 and the outdoor side hook and tilt fan profile 50, and are not exposed to the outer surface of the sliding door and window, reliably ensuring the appearance of the sliding door and window.

[0113] Furthermore, in this embodiment, the inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 are preferably both resin profiles, and the material of the resin profile is hard PVC. The inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 of the resin profile can effectively suppress heat conduction and better improve the thermal insulation capacity at the hook part of the sliding door and window. Of course, in other embodiments, the material of the inner thermal insulation cover plate 40 and the outer thermal insulation cover plate 60 can also be PA66 insulation material.

[0114] Furthermore, if Figure 4 , Figure 5 and Figure 8As shown, the indoor side hook-and-swing fan profile 30 is a thermally insulated aluminum profile, and the outdoor side hook-and-swing fan profile 50 is an ordinary aluminum profile. Therefore, only the indoor side hook-and-swing fan profile 30 is fixed with a heat insulation strip, while the outdoor side hook-and-swing fan profile 50 has no heat insulation strip. Since the indoor side thermally insulated aluminum profile, the inner thermally insulated cover plate 40 and the outer thermally insulated cover plate 60 can well achieve the thermal insulation of the hook-and-swing part, that is, the heat transfer coefficient obtained by the multiple thermal insulation structure composed of the indoor side thermally insulated aluminum profile, the inner thermally insulated cover plate 40, the outer thermally insulated cover plate 60 and the ordinary aluminum profile on the outdoor side is very close to the heat transfer coefficient obtained by the multiple thermal insulation structure composed of the indoor side thermally insulated aluminum profile, the inner thermally insulated cover plate 40, the outer thermally insulated cover plate 60 and the outdoor side thermally insulated aluminum profile. Therefore, this application only sets the indoor hook-and-slide fan profile 30 as a thermally-insulated aluminum profile, and sets the outdoor hook-and-slide fan profile 50 as an ordinary aluminum profile, which can reduce costs while ensuring the thermal insulation effect, and better improve the comprehensive competitiveness of the product. Based on this structure, the insulation structure at the hook-and-slide part of the sliding door and window involved in this application is a multiple thermal insulation structure composed of multiple thermal insulation technologies superimposed by the indoor thermally-insulated aluminum profile, the inner hard PVC resin material, the outer hard PVC resin material and the outdoor ordinary aluminum profile, to achieve the best thermal insulation effect.

[0115] Furthermore, the structure of the indoor side hook-shaped fan profile 30 is preferably: Figure 4 and Figure 5 As shown, the indoor side hook-and-sash profile 30 includes a main profile 31, an auxiliary profile 32, a first thermal insulation strip 36 extending front and rear, and a second thermal insulation strip 37 extending left and right, and the auxiliary profile 32 is distributed at the right front corner; the main profile 31 has a first connection portion 311 distributed on the rear side of the auxiliary profile 32, and a second connection portion 312 distributed on the outer side (i.e., the left side) of the auxiliary profile 32, the first thermal insulation strip 36 is fixedly arranged between the first connection portion 311 and the auxiliary profile 32 along the thickness direction of the indoor side door and window sash 10, and the second thermal insulation strip 37 is fixedly arranged between the second connection portion 312 and the auxiliary profile 32 along the width direction of the indoor side door and window sash 10, thereby fixing the main profile 31 and the auxiliary profile 32. At the same time, the first insulation strip 36 and the second insulation strip 37 are perpendicular to each other, so that the thermal insulation profile constituting the indoor side hook fan profile 30 adopts a 90° insulation strip through-strip structure, which improves the insulation effect and further improves the heat insulation capacity at the hook part of the sliding door and window.

[0116] Preferably, if Figure 4 and Figure 5 As shown, a thermal insulation cavity 38 is formed between the main profile 31 and the auxiliary profile 32 of the indoor side hook and tilt fan profile 30. The thermal insulation cavity 38 is also distributed on the inner circumference of the first insulation strip 36 and the second insulation strip 37. The indoor side hook and tilt fan profile 30 is provided with a thermal insulation foam material 80 in the thermal insulation cavity 38, thereby better improving the heat insulation capacity at the hook and tilt part of the sliding door and window.

[0117] Furthermore, the structure of the inner thermal insulation cover plate 40 is preferably as follows: Figures 4 to 7 As shown, the inner heat-insulating cover plate 40 is an integrated structure, and the inner heat-insulating cover plate 40 includes an inner cover longitudinal section 42 extending straightly forward and backward along the indoor and outdoor directions, a first inner cover transverse section 43 extending rightward from the inner cover longitudinal section 42 away from the second connection portion 312 along the width direction of the indoor door and window sash 10, and a second inner cover transverse section 44 extending leftward from the inner cover longitudinal section 42 toward the second connection portion 312 along the width direction of the indoor door and window sash 10. Among them, the inner cover longitudinal section 42 and the profile auxiliary material 32, as well as the second inner cover transverse section 44 and the second connection portion 312 are all engaged and fixed, thereby installing the inner heat-insulating cover plate 40 on the front side of the second connection portion 312 and the profile auxiliary material 32 in the indoor hook-shaped sash profile 30. The first hook portion 41 extends rightward from the front end of the inner cover longitudinal section 42 in a direction away from the second inner cover transverse section 44, and the first hook portion 41 is distributed on the outdoor side of the first inner cover transverse section 43. The second inner cover transverse section 44 is distributed in front of the second heat insulation strip 37 and is close to the second heat insulation strip 37. The right end of the first inner cover transverse section 43 passes over the left edge of the first fan panel 120 to the right; when the sliding door and window are closed, the right end of the first inner cover transverse section 43 is flush with the right edge of the outdoor hook fan profile 50, and the left end of the second inner cover transverse section 44 is flush with the left edge of the indoor hook fan profile 30, so that the first inner cover transverse section 43 and the second inner cover transverse section 44 can effectively cover the indoor hook fan profile 30 and the outdoor hook fan profile 50 in the left and right directions, and reliably ensure the heat insulation effect.

[0118] Furthermore, the interlocking structure of the indoor side hook-shaped fan profile 30 and the inner thermal insulation cover plate 40 is preferably: Figures 5 to 7 As shown, the rear end of the inner cover longitudinal section 42 is provided with a first interlocking protrusion 45 protruding to the left, and the right side of the profile auxiliary material 32 is provided with a first interlocking groove 33 for accommodating the first interlocking protrusion 45; the left end of the second inner cover transverse section 44 is provided with a second interlocking protrusion 46 protruding to the left, and a second interlocking groove 47 close to the front side of the second interlocking protrusion 46, and the right side of the second connecting portion 312 is provided with a third interlocking groove 34 for accommodating the second interlocking protrusion 46, and a third interlocking protrusion 35 accommodated in the second interlocking groove 47 and protruding to the right. In particular, there are first movable gaps between the first interlocking protrusion 45 and the groove wall of the first interlocking groove 33, between the second interlocking protrusion 46 and the groove wall of the third interlocking groove 34, and between the third interlocking protrusion 35 and the groove wall of the second interlocking groove 47, and the first movable gaps enable the inner thermal insulation cover plate 40 to be movably interlocked with the profile main material 31 and the profile auxiliary material 32. The movable interlocking structure of the inner thermal insulation cover plate 40 allows the inner thermal insulation cover plate 40 to expand and contract well at different heating temperatures during the thermal insulation process, thereby better improving the thermal insulation capacity of the hook portion of the sliding door and window.

[0119] Preferably, if Figures 5 to 7As shown, the second inner cover transverse section 44 is an inner and outer double-layer structure in the indoor and outdoor directions, so that a cover plate cavity 441 is formed in the second inner cover transverse section 44, which better improves the heat insulation capacity at the hook part of the sliding door and window.

The second hook portion 51 is preferably provided on the outdoor hook-and-tilt sash profile 50, and the second hook portion 51 extends leftward from the rear side end of the third connection portion 52 toward a direction close to the first outer cover transverse section 62 described later.

Among them, the outer cover longitudinal section 61 and the outdoor hook and sash profile 50, as well as the second outer cover transverse section and the third connection portion 52 are all engaged and fixed, thereby installing the outer heat-insulating cover plate 60 on the rear side of the outdoor hook and sash profile 50. The left end of the first outer cover cross section 62 passes over the right edge of the second fan panel 140 to the left; when the sliding door and window are closed, the left end of the first outer cover cross section 62 is flush with the left edge of the indoor hook-and-slide fan profile 30, so that the first outer cover cross section 62 and the second outer cover cross section 63 can effectively cover the outdoor hook-and-slide fan profile 50 and the indoor hook-and-slide fan profile 30 in the left and right directions, thereby reliably ensuring the heat insulation effect.

[0122] Furthermore, the interlocking structure of the outdoor hook-shaped fan profile 50 and the external thermal insulation cover plate 60 is preferably: Figures 8 to 10As shown, the front end of the outer cover longitudinal section 61 is provided with a fourth interlocking protrusion 64 protruding to the right, and the left edge of the outdoor hook fan profile 50 is provided with a fourth interlocking groove 53 for accommodating the fourth interlocking protrusion 64; the right end of the second outer cover transverse section 63 away from the outer cover longitudinal section 61 is provided with a fifth interlocking protrusion 65 protruding to the right, and the left side of the third connecting portion 52 is provided with a fifth interlocking groove 54 for accommodating the fifth interlocking protrusion 65. In particular, there is a second movable gap between the fourth interlocking protrusion 64 and the groove wall of the fourth interlocking groove 53, and between the fifth interlocking protrusion 65 and the groove wall of the fifth interlocking groove 54, and the second movable gap enables the outer heat-insulating cover plate 60 to be movably interlocked with the outdoor hook fan profile 50. The movable interlocking structure of the outer heat-insulating cover plate 60 allows the outer heat-insulating cover plate 60 to expand and contract well under different heating temperatures during the heat-insulating process, and better improves the heat-insulating capacity of the hook part of the sliding door and window.
