[0002] Inward-tilting and side-sliding doors and windows combine the advantages of casement doors and windows and sliding doors and windows. They can achieve micro-ventilation and opening functions through inward tilting and side sliding without occupying indoor space.

[0003] Glass sash refers to window or door sashes equipped with glass, which are mainly used for lighting, ventilation and other functions of buildings. In modern buildings, glass sashes are not only the basic components of windows, but also an important element connecting indoor and outdoor spaces. The design and manufacture of glass sashes involve knowledge in many fields such as architectural aesthetics, structural mechanics, and material science. The quality of its design and installation directly affects the beauty, safety and functionality of the building.

[0004] The glass sash of the inward-tilted and side-sliding doors and windows includes: Glass: The core part of the glass sash, usually made of tempered glass or insulating glass to provide good thermal insulation and sound insulation;

[0005] Fixed frame: It can be aluminum alloy, wood or other synthetic materials, used to install the glass in the door frame or window frame;

[0006] Movable frame: used to fix glass, which can be moved on the fixed frame to open or close doors and windows;

[0007] Hardware accessories: including but not limited to hinges, handles, locks, etc., which are necessary components for controlling the opening and closing of glass sashes and affect the practicality and durability of doors and windows;

[0008] Sealing strip: Mainly used to improve the sealing performance of glass sashes and prevent the penetration of air and moisture.

[0009] Existing doors and windows (including inward-tilting and side-sliding doors and windows) have some setting problems, mainly manifested in the upper rails of the door and window fixed frames. The surface of the fixed upper rails of traditional doors and windows facing the outdoor side is exceeded by other components of the door and window glass leaf upper rail system. Rainwater and other liquids can fall on other components that exceed the fixed upper rails, and then slowly penetrate into the glass leaf frame through the connection between the fixed upper rails and other components. On the one hand, rainwater and other liquids are in contact with various components of the glass leaf frame for a long time, which may cause the glass leaf frame or the hardware accessories inside the frame to rust and damage. On the other hand, the liquid entering the glass leaf frame may penetrate into the indoor side of the door and window, weakening the waterproofness of the drifting glass leaf door and window.

[0019] In some embodiments, in the height direction of the first body, a dimension H of a portion of the second component that exceeds a side of the first component close to the gauze fan satisfies 20 mm ≤ H ≤ 40 mm.

[0020] In the technical solution of the embodiment of the present application, the size of the part of the second component that exceeds the first component on the side close to the screen fan is H. When 20mm≤H≤40mm is satisfied, the interior of the door and window glass sash upper rail system formed by coupling the fixed upper rail of the door and window, the screen fan and the movable glass sash of the door and window reserves sufficient space for the installation of metal accessories. At the same time, the components of the door and window glass sash upper rail system can limit each other to reduce the risk of deformation or displacement damage of the components.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0044] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0047] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0048] The door and window fixed upper rail and door and window glass leaf upper rail system provided in the present application can be applied to various types of doors and windows. The present application is described using the inward-tilting and sliding doors and windows as an example.

[0049] The inventors of the present invention noticed that the surface of the fixed upper rail of the inward-tilted and side-sliding doors and windows facing the outdoor side is exceeded by other components of the door and window glass leaf upper rail system (such as screen leaves, door and window movable glass leaves, etc.), and rainwater and other liquids can fall on and gather in large quantities on the other components exceeding the fixed upper rail. When there is a lot of rainwater and other liquids on the other components exceeding the fixed upper rail of the doors and windows, the water and other liquids will fit into the connection between the fixed upper rail of the doors and windows and the other components, and then slowly penetrate into the glass leaf frame through the connection between the fixed upper rail and the other components. On the one hand, rainwater and other liquids may contact with the various components of the glass leaf frame for a long time, which may cause the glass leaf frame or the hardware accessories on the inside of the frame to rust and be damaged. On the other hand, the liquid entering the glass leaf frame may penetrate into the indoor side of the doors and windows, thereby weakening the waterproofness of the drifting glass leaf doors and windows.

[0050] Based on the above considerations, in order to alleviate the problems of easy rust and reduced waterproof performance of the door and window glass leaf upper track system due to water ingress, the inventors have designed a door and window movable glass leaf after in-depth research, including a first main body, a second main body and a third main body connected between the first main body and the second main body, wherein the first surface of the first main body facing the outdoor side is flush with the surfaces of other components facing the outdoor side, so that rainwater and other liquids falling on the first surface can directly flow or drip onto the surfaces of other components facing the outdoor side, and reduce the probability of rainwater and other liquids contacting the connection between the first main body and other components to reduce the probability of rainwater liquid penetrating into the door and window glass leaf upper track system, so that the inner side of the door and window glass leaf upper track system is easily kept in a dry state, reducing the risk of rust on the door panel glass leaf frame and its inner hardware accessories after encountering water, and at the same time, reducing the risk of water on the outdoor side gradually penetrating into the indoor side through the connection between the door and window fixed upper track and other components, thereby improving the waterproof performance of the door and window glass leaf upper track system.

[0051] Please refer to Figure 1 , Figure 1 A front view of door and window glass sashes provided in some embodiments of the present application, wherein the door and window glass sashes are arranged on the ground or on a work platform, and the door and window glass sashes include a fixed frame 1, a movable frame 2 and a glass 3, wherein the glass 3 is fixed to the movable frame 2, and the movable frame 2 is slidably arranged in the fixed frame 1, and the fixed frame 1 is fixedly installed on the door frame or the window frame.

[0052] Please refer to Figure 1 and Figure 2 The movable frame 2 and the fixed frame 1 constitute the door and window glass leaf frame. The movable frame 2 and the fixed frame 1 are both composed of four edges. The edge of the movable frame 2 farthest from the ground or the work platform is the door and window movable glass leaf 20, and the edge of the fixed frame 1 farthest from the ground or the work platform is the door and window fixed upper rail 10.

[0053] According to some embodiments of the present application, optionally, Figure 3 to Figure 6 As shown, the present application provides a door and window fixed upper rail 10, which can be coupled with a screen fan 3 and a door and window movable glass fan 20, and the door and window fixed upper rail 10 includes a first main body 100, a second main body 101 and a third main body 102; the first main body 100 includes a first surface 1000 facing the outdoor outside; the second main body 101 includes a second surface 1010 facing the indoor inside; the third main body 102 connects the first main body 100 and the second main body 101; wherein, the first surface 1000 is flush with the surface of the screen fan 3 facing the outdoor outside, the first main body 100 is sealedly connected to the screen fan 3, the second surface 1010 is flush with the surface of the door and window movable glass fan 20 facing the indoor inside, and the second main body 101 is sealedly connected to the door and window movable glass fan 20.

[0054] Taking the inward-tilted and side-sliding door and window glass sash as an example, the top mentioned in this application is the side of the inward-tilted and side-sliding door and window glass sash facing away from the ground, and the bottom mentioned in this application is the side of the inward-tilted and side-sliding door and window glass sash close to the ground or the work platform.

[0055] The door and window fixed upper rail 10 can be fixedly installed on a wall or a beam.

[0056] The door and window fixed upper rail 10 can be a thermally-insulated aluminum profile, which is also called a thermally-insulated aluminum profile, a thermally-insulated aluminum alloy profile, a thermally-insulated aluminum alloy, a thermally-insulated cold and hot bridge profile, and a thermally-insulated aluminum-plastic composite profile. It has better performance than ordinary aluminum alloy profiles.

[0057] When the door and window fixing upper rail 10 is a thermally-insulated aluminum profile, the first body 100 and the second body 101 may be aluminum alloy profiles, and the third body 102 may be a thermoplastic mixed material.

[0058] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in industry. Pure aluminum has a low density and a face-centered cubic structure, so it has high plasticity and is easy to process. It can be made into various profiles and plates with good corrosion resistance. However, the strength of pure aluminum is very low. Aluminum is strengthened by adding alloy elements and using heat treatment methods, which results in a series of aluminum alloys. The alloys formed by adding certain elements can maintain the advantages of pure aluminum such as light weight while also having higher strength.

[0059] The first body 100 includes a first surface 1000 facing the outside of the room, the first surface 1000 is flush with the surface of the screen fan 3 facing the outside of the room, the first body 100 is sealed and connected to the screen fan 3, the screen fan 3 will not block the movement of liquids such as rainwater under the action of gravity, so that the rainwater and other liquids falling on the first surface 1000 can directly flow or drip onto the surface of other components facing the outside of the room. In addition, the flow direction of the air near the first surface 1000 is parallel to the first surface 1000 due to the obstruction of the first surface 1000. Since the first surface 1000 is flush with the surface of the screen fan 3 facing the outside of the room, the airflow parallel to the first surface 1000 can smoothly flow through the gap that may exist between the first surface 1000 and the screen fan 3. To the surface of the screen fan 3, blow the rainwater that may fall into the gap between the first surface 1000 and the screen fan 3, so that they can also fall in the direction parallel to the first surface 1000, further reducing the probability of rainwater and other liquids contacting the connection between the first body 100 and the screen fan 3, reducing the risk of rainwater entering the inner side of the components coupled by the door and window fixed upper rail 10, the screen fan 3 and the door and window movable glass fan 20, making it easy to maintain the inner side of the door and window glass fan upper rail system in a dry state, reducing the risk of rust on the metal accessories on the inner side of the door and window fixed upper rail 10, the screen fan 3 and the door and window movable glass fan 20 and the door and window glass fan upper rail system when encountering water, and also reducing the risk of water and other liquids penetrating into the inner side of the door and window glass fan, thereby improving the waterproof effect of the door and window glass fan;

[0060] The second main body 101 includes a second surface 1010 facing the indoor side, and the second surface 1010 is flush with the surface of the door and window movable glass fan 20 facing the indoor side. The second main body 101 is sealed and connected to the door and window movable glass fan 20, so that liquid that may fall on the second surface 1010 on the indoor side can directly flow or drip onto the surface of the door and window movable glass fan 20 facing the indoor side, reducing the risk of liquid contacting the connection between the second main body 101 and the door and window movable glass fan 20 and then penetrating into the inner side of the door and window glass fan upper track system formed by coupling the door and window fixed upper track 10, the screen fan 3 and the door and window movable glass fan 20, making it easy to maintain the inner side of the door and window glass fan upper track system in a dry state, reducing the risk of rusting of metal accessories on the inner side of the door and window fixed upper track 10, the screen fan 3, the door and window movable glass fan 20 and the door and window glass fan upper track system when exposed to water.

[0061] According to some embodiments of the present application, optionally, Figure 3 to Figure 6 As shown, the first main body 100 includes a first component part 1001 and a second component part 1002, and the first component part 1001 is mechanically connected to the third main body 102; the second component part 1002 extends along the height direction of the first main body 100, and the second component part 1002 is closer to the outdoor side than the first component part 1001, and the second component part 1002 has a first surface 1000 and a third surface 1003 opposite to each other along the thickness direction of the first main body 100, and the third surface 1003 is sealed and connected to the screen fan 3.

[0062] The first component 1001 can be buckled with the third body 102 through a slot.

[0063] The first component part 1001 may be connected to the third surface 1003 .

[0064] In the height direction of the first main body 100, the first component 1001 can be arranged on the third surface 1003 in an area away from the screen fan 3, so that the internal space of the door and window glass fan upper track system is larger.

[0065] Compared with the first component 1001, the second component 1002 is closer to the outdoor side. The second component 1002 has a first surface 1000 and a third surface 1003 which are opposite to each other along the thickness direction of the first main body 100. The third surface 1003 is sealed with the screen fan 3, so that the position where the first main body 100 is sealed with the screen fan 3 and the first surface 1000 which is in direct contact with liquids such as rainwater are blocked by the first component 1001, thereby reducing the probability of liquids such as rainwater on the outdoor side entering the door and window glass upper track system through the connection between the first component 1001 and the screen fan 3.

[0066] According to some embodiments of the present application, optionally, Figure 3 to Figure 6 As shown, the third surface 1003 is provided with a first card slot 1004 .

[0067] The first card slot 1004 can be arranged at the edge of the third surface 1003 close to the gauze fan 3; or, the bottom end of the second component 1002 can exceed the first card slot 1004, so that the liquid flowing to the bottom end of the second component 1002 can gather at this position until the weight of the gathered liquid increases to the point where it is difficult to adhere to the bottom end of the second component 1002 and drips from the bottom end of the second component 1002, thereby reducing the risk of the liquid flowing through the bottom end of the second component 1002 and contacting the first card slot 1004.

[0068] The third surface 1003 is provided with a first card groove 1004. On the one hand, the first card groove 1004 can be used to accommodate a seal that seals the first body 100 and the screen fan 3, thereby increasing the connection stability between the first body 100 and the seal, thereby improving the sealing effect between the first body 100 and the screen fan 3; on the other hand, the provision of the first card groove 1004 changes the sealing position between the first body 100 and the screen fan 3 from the third surface 1003 to the opening of the first card groove 1004, thereby increasing the size of the sealing position between the first surface 1000 of the first component 1001 and the first body 100 and the screen fan 3 in the thickness direction of the first body 100, lengthening the distance that the liquid needs to flow to contact the connection between the first body 100 and the screen fan 3, thereby reducing the probability of the liquid entering the door and window glass sash upper track system through the connection between the first body 100 and the screen fan 3.

[0069] According to some embodiments of the present application, optionally, Figure 3 and Figure 5 As shown, in the height direction of the first body 100, the dimension of the portion of the second component 1002 that exceeds the first component 1001 on the side close to the yarn fan 3 is H, which satisfies 20 mm ≤ H ≤ 40 mm.

[0070] When H is less than 20 mm, the size of the internal cavity of the door and window glass leaf upper track system is small, and only small-sized metal accessories can be used. Small-sized metal accessories are difficult to meet the strength requirements of the inward-tilting and sliding door and window glass leaves during use, resulting in a short service life of the inward-tilting and sliding door and window glass leaves;

[0071] When H>40mm, the size of the internal cavity of the door and window glass sash upper track system is too large, the mutual limiting effect of the various components of the door and window glass sash upper track system is weak, and the probability of deformation of the various components of the glass sash frame is high.

[0072] The dimension of the portion of the second component 1002 that exceeds the first component 1001 on the side close to the screen fan 3 is H. When 20mm≤H≤40mm is satisfied, the interior of the door and window glass sash upper track system formed by coupling the door and window fixed upper track 10, the screen fan 3 and the door and window movable glass sash 20 reserves sufficient space for the installation of metal accessories. At the same time, the components of the door and window glass sash upper track system can limit each other to reduce the risk of deformation or displacement damage of the components.

[0073] According to some embodiments of the present application, optionally, Figure 3 to Figure 6 As shown, the second main body 101 includes a third component part 1011 and a fourth component part 1013.

[0074] The fourth surface 1012 can be lower than the fifth surface 1014, and the third component 1011 is used to be fixed to a wall or a beam by means of screws, rivets and other components; or, the fourth surface 1012 can be higher than the fifth surface 1014, and the fourth component 1013 is used to be fixed to a wall or a beam by means of screws, rivets and other components.

[0075] The second main body 101 includes a third component 1011 and a fourth component 1013, the third component 1011 includes a fourth surface 1012, the fourth component 1013 includes a fifth surface 1014, the fourth surface 1012 is not flush with the fifth surface 1014, and two adjacent cavities (hereinafter referred to as the first channel 104 and the second channel 105) are divided on the inner side of the door and window glass upper track system through the structure of the third component 1011 and the fourth component 1013, so that the accessories installed in the adjacent cavities are not easy to interfere with each other.

[0076] According to some embodiments of the present application, optionally, Figure 3 to Figure 6 As shown, the fourth surface 1012 is provided with a second card slot 10120 , the fifth surface 1014 is provided with a third card slot 10140 , and the third card slot 10140 is provided with a track plug-in 1015 .

[0077] When the fourth surface 1012 is lower than the fifth surface 1014 , the fourth surface 1012 may be lower than the third card slot 10140 ; ​​when the fourth surface 1012 is higher than the fifth surface 1014 , the fifth surface 1014 may be lower than the second card slot 10120 .

[0078] The fourth surface 1012 is provided with a second card slot 10120, and the fifth surface 1014 is provided with a third card slot 10140. Both the second card slot 10120 and the third card slot 10140 can be used to install metal accessories to enhance the connection stability between the second body 101 and the metal accessories. The third card slot 10140 is provided with a track plug-in 1015. The upper pulley assembly and the first buffer accessory for supporting the movement of the movable glass leaf 20 of the door and window are installed through the track plug-in 1015. The first buffer accessory can buffer part of the force exerted on the movable glass leaf 20 of the door and window when the movable glass leaf 20 is in an inwardly tilted state and is subjected to external force, so that the movable glass leaf 20 of the door and window is not easily returned to a closed state by itself due to external force.

[0079] According to some embodiments of the present application, optionally, Figure 3 and Figure 5 As shown, the fourth surface 1012 is lower than the fifth surface 1014 , a sixth surface 1016 is formed between the fourth surface 1012 and the fifth surface 1014 , and the sixth surface 1016 is provided with a fourth slot 10160 .

[0080] The sixth surface 1016 may be perpendicular to the thickness direction of the second body 101 .

[0081] The fourth slot 10160 may be directly opposite to the sealed connection between the fourth component 1013 and the movable glass leaf 20 of the door or window.

[0082] The metal fittings located in the area facing the fifth surface 1014 and the sixth surface 1016 are close to the indoor side and may be subjected to pulling force toward the indoor side. A sixth surface 1016 is formed between the fourth surface 1012 and the fifth surface 1014. The sixth surface 1016 is provided with a fourth card slot 10160. The fourth card slot 10160 faces the indoor side. The fourth card slot 10160 is used to install hardware for controlling the opening and closing of the upper pulley assembly, thereby controlling the opening and closing of the movable glass leaf 20 of the door and window.

[0083] In some embodiments, a second buffer accessory can also be installed between the fourth slot 10160 and the hardware that controls the opening and closing of the upper pulley assembly. The second buffer accessory can prevent the movable glass leaf 20 from opening too fast and having a large inertia when the movable glass leaf 20 slides on the door and window fixed frame 1, causing the movable glass leaf 20 to collide with the door and window fixed frame 1 and damage the sliding parts and the movable glass leaf 20 (it can be understood that the movable glass leaf 20 plays a role of decelerating movement by contacting and cooperating with the buffer accessory during the sliding process).

[0084] In other embodiments, the first buffer accessory can buffer the force applied to the movable glass sash 20 when it is in a tilted state, the second buffer accessory can buffer the force applied to the movable glass sash 20 when it is in a sliding state, the track plug-in 1015 can be installed with any one of the first buffer accessory and the second buffer accessory, and the fourth slot 10160 can be installed with any one of the first buffer accessory and the second buffer accessory.

[0085] According to some embodiments of the present application, optionally, the third body 102 is a heat insulation strip.

[0086] The thermal insulation strip is an indispensable part of the thermal insulation aluminum alloy doors and windows. Its main function is to reduce the transfer of heat and maintain the stability of indoor temperature. The material selection of the thermal insulation strip has a crucial impact on its performance. At present, the main thermal insulation strip materials on the market include PA66 and PVC.

[0087] PA66 insulation strips are mainly composed of polyamide 66 and 25% glass fiber, with good tensile strength and thermal stability. Its tensile strength can reach 126N / mm 2 The thermal deformation temperature is as high as 240°, which is consistent with the linear expansion coefficient of aluminum alloy, ensuring the close combination of the thermal insulation strip and the aluminum profile. PA66 thermal insulation strips are resistant to aging, high temperature and corrosion, and are suitable for a variety of climatic conditions, especially in high temperature environments. In addition, PA66 thermal insulation strips also have good flame retardant properties, and can automatically extinguish after leaving the fire source, which is highly safe.

[0088] The main raw material of PVC insulation strip is PVC resin powder plus 25% calcium carbonate, which has low cost, but the tensile strength is only 70N / mm 2About 100°, the thermal deformation temperature is 90°. PVC insulation strips are prone to aging, have poor thermal stability, produce harmful gases when heated or burned, and have relatively poor environmental performance. The difference in linear expansion coefficient with aluminum alloys may cause the insulation strips to be not firmly connected to the aluminum profiles, affecting the overall performance of doors and windows.

[0089] When choosing insulation strips, PA66 material should be given priority, especially for doors and windows that need long-term durability and have high requirements for thermal insulation performance. Although the cost of PA66 is relatively high, its superior performance ensures the long-term use of doors and windows and good thermal insulation effect, and it is more cost-effective in the long run.

[0090] The third body 102 is an insulation strip, which can block the heat exchange process between the indoor and outdoor sides of the doors and windows through the glass sash frame, so that the indoor temperature can be maintained at a more comfortable level with less energy consumption, reducing the energy required to replenish the temperature lost due to indoor and outdoor heat exchange, thereby improving the energy-saving and thermal insulation effects of the door and window glass sash upper track system.

[0092] The fixed upper rail 10 of the door and window can be tilted and slid inwardly to change the moving direction of the movable glass leaf 20 of the door and window.

[0093] The first seal 4 is arranged between the first body 100 and the screen 3; the second seal 5 is arranged between the screen 3 and the door and window movable glass fan 20; the third seal 6 is arranged between the first body 100, the second body 101, the third body 102 and the door and window movable glass fan 20; the fourth seal 7 is arranged between the second body 101 and the door and window movable glass fan 20; the fifth seal 8 is arranged between the second body 101 and the door and window movable glass fan 20, and the fifth seal 8 is closer to the indoor side than the fourth seal 7, so that there is a quadruple seal of the first seal 4 (or the second seal 5), the third seal 6, the fourth seal 7 and the fifth seal 8 between the indoor side and the indoor side of the door and window glass fan, so that the door and window glass fan upper track system provided in the present application has better air tightness, water tightness and energy-saving effect; wherein, the first body 100, the first seal 4, the screen 3, the second seal 5, the door and window movable glass fan 20 and the third seal 6 surround the first cavity 103, the screen 3 can be set A through hole is provided to connect the first cavity 103 with the outdoor side of the door and window, so that the liquid entering the door and window glass leaf upper track system from the outdoor side can be concentrated and blocked in the first cavity 103, and then discharged to the outdoor side through the through hole on the screen fan 3, thereby reducing the probability of the liquid contacting the metal fittings located in the first channel 104 and the second channel 105, and also reducing the risk of the liquid penetrating into the indoor side of the door and window; the second body 101, the third sealing member 6, the door and window movable glass leaf 20 and the fourth sealing member 7 form the first channel 104, and the first channel 104 can be used to install the locking member; the second body 101, the fourth sealing member 7, the door and window movable glass leaf 20 and the fifth sealing member 8 form the second channel 105, and the second channel 105 can be used to install the upper pulley assembly, and the locking member and the upper pulley assembly can be installed in different channels, thereby reducing the mutual interference between the locking member and the upper pulley assembly, and the arrangement of the third sealing member 6 and the fourth sealing member 7 can prevent water from penetrating from the outdoor side to the indoor side or into the indoor profile.

[0094] According to some embodiments of the present application, optionally, Figure 3 As shown, the screen fan 3 has a seventh surface 30 facing the outdoor side, and in the height direction of the door and window fixing upper rail 10, there is a gap of size L between the first surface 1000 and the seventh surface 30, satisfying 5mm≤L≤7mm.

[0095] When L is less than 5 mm, the size of the gap between the first surface 1000 and the seventh surface 30 is small, and liquid such as rainwater entering the gap can easily fill the gap between the first surface 1000 and the seventh surface 30 and then flow to the connection between the first body 100 and the screen fan 3. The liquid may penetrate into the inner side of the door and window glass sash upper track system through the connection between the first body 100 and the screen fan 3.

[0096] When L>7mm, the size of the gap between the first surface 1000 and the seventh surface 30 is relatively large, and the airflow around the first surface 1000 and parallel to the first surface 1000 cannot flow smoothly to the seventh surface 30. The airflow around the first surface 1000 may tend to pour into the gap between the first surface 1000 and the seventh surface 30, thereby blowing rainwater and other liquids falling near the gap between the first surface 1000 and the seventh surface 30 into the gap between the first surface 1000 and the seventh surface 30, causing the amount of rainwater and other liquids in the gap between the first surface 1000 and the seventh surface 30 to gradually increase until the gap between the first surface 1000 and the seventh surface 30 is filled. The liquid filling the gap between the first surface 1000 and the seventh surface 30 may penetrate into the inner side of the door and window glass sash upper track system through the connection between the first body 100 and the screen fan 3.

[0097] The screen fan 3 has a seventh surface 30 facing the outside of the room, and there is a gap of size L between the first surface 1000 and the seventh surface 30. When 5mm≤L≤7mm is satisfied, the gap between the first surface 1000 and the seventh surface 30 is not easily filled by liquid such as rainwater falling into the gap, so that the liquid such as rainwater falling into the gap is not easy to contact the connection between the first body 100 and the screen fan 3. In addition, the airflow around the first surface 1000 parallel to the first surface 1000 can flow smoothly to the seventh surface 3 0, rainwater and other liquids that may fall into the gap between the first surface 1000 and the seventh surface 30 are blown away, and the direction of this part of rainwater and other liquids is changed so that it is not easy to fall into the gap between the first surface 1000 and the seventh surface 30. In summary, when 5mm≤L≤7mm is satisfied, rainwater and other liquids on the outdoor side are not easy to fall into the gap between the first surface 1000 and the seventh surface 30 and are not easy to contact with the connection between the first body 100 and the screen fan 3, thereby reducing the risk of rainwater and other liquids penetrating into the door and window glass fan upper track system.
