Description

Technical Field

[0001] This application relates to the field of building profile technology, and in particular to a pull-up window and a hook-locking assembly. Background Technology

[0002] A pull-out window is a type of window that opens and closes by sliding sashes. A pull-out window may include multiple sashes, which can cover the entire window area. The sashes that can slide are called movable sashes, and the sashes that cannot slide are called fixed sashes. The movable and fixed sashes of a pull-out window may include a frame and filler such as glass mounted on the frame, used to separate the indoor and outdoor environments.

[0003] Because the movable and fixed fans can move relative to each other, and due to manufacturing processes, the movable fan needs to be sealed to the ventilation section when closed. To improve the sealing effect, sealing components can be installed on the movable fan and the ventilation section. For example, a sealing strip can be installed at the contact gap between the movable and fixed fans. When the sliding window is closed, the sealing strip can be elastically deformed by the pressure of the frame of the movable fan and the ventilation section, thus sealing the contact gap between the movable fan and the ventilation section.

[0004] However, the sealing components are elastic and will generate a reaction force when the sliding sash is closed. In addition, the outdoor wind pressure on the sliding sash will result in a poor sealing effect after the sliding sash is closed, which will reduce the airtightness and heat insulation performance of the sliding window.

[0017] Optionally, the second hooking part includes a hooking part and a second fixing plate; the hooking part is connected to the profile of the fixed fan through the second fixing plate; the second hooking member is disposed on the profile of the movable fan.

[0018] Optionally, the hook-locking assembly further includes a self-lubricating element, which is disposed within the hook portion or on the hook member.

[0039] To make the objectives, technical solutions, and advantages of some embodiments of this application clearer, the technical solutions of some embodiments of this application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0040] It should be noted that the brief descriptions of terms in some embodiments of this application are only for the convenience of understanding the implementation methods described below, and are not intended to limit the implementation methods of some embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0041] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0042] In the embodiments of this application, such as Figure 1 As shown, the pull-out window includes a frame 1, a movable sash 2, and a fixed sash 3. The frame 1 is installed on the building window wall and can be a rectangular frame structure or a U-shaped structure. When the frame 1 is a U-shaped structure, it also has a mullion profile. Both the movable sash 2 and the fixed sash 3 are installed inside the frame 1, but the fixed sash 3 is fixedly installed inside the frame 1, while the movable sash 2 is movably installed inside the frame 1. The movable sash 2 and the fixed sash 3 can be rectangular frame structures, and both can be fitted with glass or other barrier materials. When the movable sash 2 is closed, the movable sash 2 and the fixed sash 3 can completely seal the frame 1, sealing the interior space of the building.

[0043] like Figure 2 As shown, the fixed sash 3 can be positioned on the side of the area enclosed by the frame 1 where ventilation is not required, while the movable sash 2 can be positioned on the side where ventilation is required. For example, in a vertically opening and closing type of sliding window, the fixed sash 3 is fixed to the lower part of the frame 1, while the movable sash 2 is positioned on the upper part of the frame 1, and the movable sash 2 can move vertically. When ventilation is required, the movable sash 2 is lowered to open the upper area of ​​the sliding window for ventilation; when ventilation is not required, the movable sash 2 is raised to close the upper area of ​​the sliding window.

[0044] In some embodiments, such as Figure 3 , Figure 4As shown, to facilitate the movement of the movable sash 2, a slide rail 11 can be provided on the frame 1 to assist in the movement of the movable sash 2. For vertically opening and closing pull-out windows, the slide rail 11 can be provided on the two uprights of the frame 1. The movable sash 2 is provided with a sliding shaft 21, which can move within the slide rail 11. For example, for a vertically opening and closing pull-out window, an S-shaped slide rail 11 is provided on the two uprights of the frame 1, and sliding shafts 21 are respectively provided at the top and bottom positions on both sides of the movable sash 2, with the sliding shafts 21 protruding from the side profile of the movable sash 2. After assembly, the sliding shafts 21 can enter the slide rail 11 and move relative to the slide rail 11, thus driving the entire movable sash 2 to move along the slide rail 11, realizing the opening and closing of the pull-out window.

[0045] During the opening and closing of the sliding window, the movable sash 2 can be driven by the window motor 6. The window motor 6 can be located at the top of the frame or inside the frame profile of either the movable sash 2 or the fixed sash 3. Figure 1 As shown, in some embodiments, the window unit 6 includes a drive motor, a transmission component, a traction rope, and a lifting pulley system. The drive motor is connected to one end of the traction rope via the transmission component, and the other end of the traction rope passes through the lifting pulley system and is connected to the movable sash 2. During the opening of the window, the drive motor rotates forward, loosening the traction rope through the transmission component, causing the movable sash 2 to move downward along the slide rail, increasing the opening degree of the window. During the closing of the window, the drive motor rotates in reverse, tightening the traction rope through the transmission component, causing the movable sash 2 to move upward along the slide rail, decreasing the opening degree of the window.

[0046] In some embodiments, for vertically opening and closing pull-out windows, when the movable sash 2 is moved to its highest position, the pull-out window is in a fully closed state, and the pull-out window should meet the building's sealing requirements. However, since there is a contact gap between the movable sash 2 and the fixed sash 3, it will affect the overall sealing performance of the pull-out window. Therefore, sealing devices need to be added to both the movable sash 2 and the fixed sash 3. The sealing devices can block, seal, and compress the contact gap between the movable sash 2 and the fixed sash 3 to improve the sealing performance of the pull-out window.

[0047] For example, the sealing device can be a fixed plate set at the contact gap between the movable fan 2 and the fixed fan 3. The fixed plate can cover the contact gap between the movable fan 2 and the fixed fan 3 and extend the travel distance of the airflow, making it difficult for air and dust to enter the indoor environment through the contact gap.

[0048] However, since the fixing plate only covers the contact gap, there is no direct or tight contact between the fixing plate and the movable fan 2 or the fixed fan 3, resulting in gaps still existing between them. Therefore, the problem of incomplete sealing persists after prolonged use. To address this, in some embodiments, a tight-contact sealing device can be used to further improve the sealing effect.

[0049] For example, the sealing device may also include a sealing strip disposed at the contact gap between the movable sash 2 and the fixed sash 3. The sealing strip can be elastically deformed by the pressure of the frame of the movable sash 2 and the fixed sash 3 when the window is closed, thereby sealing the contact gap between the movable sash 2 and the fixed sash 3.

[0050] However, the sealing components are elastic and will generate a reaction force when the sliding sash is closed. In addition, the outdoor wind pressure on the sliding sash will result in a poor sealing effect after the sliding sash is closed, which will reduce the airtightness and heat insulation performance of the sliding window.

[0051] To address the issue of low sealing performance of the aforementioned pull-up window, some embodiments of this application also provide a pull-up window. This pull-up window can be the structure provided in the above embodiments, specifically, it can include: a frame 1, a movable sash 2, and a fixed sash 3. The movable sash 2 is movably connected to the frame 1 to open and close the entire window, while the fixed sash 3 is fixedly connected to the frame 1 and cooperates with the movable sash 2 to close the pull-up window. To improve the sealing performance of the pull-up window, it also includes a hook-and-lock assembly 4.

[0052] Among them, such as Figure 5 As shown, the hook-and-lock assembly 4 includes a hook member 41 and a hook part 42, which can be selectively hooked together. One of the hook member 41 and the hook part 42 is disposed on the movable sash 2, and the other of the hook member 41 and the hook part 42 is disposed on the mullion profile of the fixed sash 3 or the frame 1. That is, if the hook member 41 is disposed on the movable sash 2, then the hook part 42 is disposed on the mullion profile of the fixed sash 3 or the frame 1. And when the hook member 41 is disposed on the mullion profile of the fixed sash 3 or the frame 1, then the hook part 42 is disposed on the movable sash 2.

[0053] Hook 41 and hook part 42 are two mating parts that can hook together, and their specific shapes can be set according to the profile structure. For example, hook 41 can be a hook-shaped structure protruding from the main body of the profile, while hook part 42 can be a groove-shaped structure recessed into the main body of the profile. The positions of hook 41 and hook part 42 can be set according to the profile structure of the movable sash 2 and the fixed sash 3. In order to obtain a better sealing effect, hook 41 and hook part 42 should be set on the profile frames of the movable sash 2 and the fixed sash 3 that are close to each other when the sliding window is closed. For example, for a vertically opening and closing sliding window, the profiles that are close to each other are the lower frame of the movable sash 2 and the upper frame of the fixed sash 3. Then hook 41 can be set on the lower frame of the movable sash 2, and hook part can be set on the upper frame of the fixed sash 3.

[0054] After hooking, the hook 41 and hook part 42 should facilitate window sealing. To this end, contact surfaces can be provided on the hook 41 and hook part 42 respectively. These contact surfaces can come into contact with each other when the window is closed, forming a certain clamping force. This clamping force allows the material of the hook 41 or hook part 42 to undergo a certain degree of elastic deformation, improving the sealing performance. Simultaneously, the contact surfaces of the hook 41 and hook part 42 can be inclined in the same direction to allow the hook 41 to enter the hook part 42 during the closing of the movable sash 2.

[0055] For example, a fixing plate extends from the lower frame profile of the movable sash 2. The side of the fixing plate facing indoors is flat, while the side facing outdoors has a hook-like structure to form a hook 41. Correspondingly, a groove is formed on the side of the upper frame of the fixed sash. The groove has an L-shaped cross-section to form a hook portion 42. Both the hook-like structure of the hook 41 and the L-shaped groove of the hook portion 42 have inclined surfaces. During the closing process of the sliding window, the movable sash 2 first moves upwards and then moves diagonally upwards along the slide rail 11. The hook 41 can move with the movable sash 2, allowing the hook-like structure to enter the hook portion 42. Furthermore, as the movable sash 2 continues to move diagonally upwards, the inclined surfaces on the hook 41 and the hook portion 42 come into contact with each other and generate a certain clamping force, thereby sealing the contact gap between the movable sash 2 and the fixed sash 3, achieving a sealing effect.

[0056] Obviously, one of the hooking member 41 and the hooking part 42 is provided on the movable sash 2, and the other of the hooking member 41 and the hooking part 42 is provided on the fixed sash 3. This refers to the hooking member 41 and the hooking part 42 that cooperate with each other in the same set of hooking and locking components 4. In some embodiments, the pull-out window may include multiple sets of hooking and locking components 4, and the multiple sets of hooking and locking components 4 may be provided at multiple positions on the movable sash 2 and the fixed sash 3 respectively.

[0057] The hooking member 41 and hooking part 42 in different sets of hook-locking components 4 can be respectively set on the movable fan 2 and the fixed fan 3 according to needs and specific shapes. For example, the hooking member 41 in the first set of hook-locking components 4 is set on the movable fan 2, while the hooking member 41 in the second set of hook-locking components 4 can be set on the fixed fan 3. Correspondingly, the hooking part 42 in the first set of hook-locking components 4 is set on the fixed fan 3, while the hooking part 42 in the second set of hook-locking components 4 can be set on the movable fan 2.

[0058] As can be seen from the above technical solutions, by setting the hook part 41 and the hook section 42, a selective hooking sealing method can be achieved between the movable sash 2 and the fixed sash 3 when the pull-up window is closed. Since both the hook part 41 and the hook section 42 can be made of the same material as the profile or of the same strength, the hook part 41 and the hook section 42 are affected by the environment to the same extent as the profile, thus alleviating the problem of poor sealing caused by premature aging of the sealing device. Furthermore, the hook part 41 and the hook section 42 can be directly designed as an integral structure with the movable sash 2 or the fixed sash 3, simplifying the assembly process, reducing assembly gaps generated during assembly, and improving the sealing performance of the pull-up window.

[0059] In the above embodiments, the hook-locking assembly 4 can seal the contact gap through the hooking action of the hook member 41 and the hook part 42. The more hook members 41 and the hook part 42 there are, the more areas that form a hooking action between the movable sash 2 and the fixed sash 3, and the more obvious the improvement in the sealing effect of the pull-up window. Therefore, the sealing performance can be further improved by increasing the number of hook members 41 and the hook part 42.

[0060] like Figure 6 As shown, in some embodiments, the hook member 41 includes a first hook member 411 and a second hook member 412, and the hook portion 42 includes a first hook portion 421 and a second hook portion 422. The first hook member 411 and the first hook portion 421 are disposed on one side of the pull-up window, such as the indoor side, and the second hook member 412 and the second hook portion 422 are disposed on the side of the pull-up window away from the first hook member 411, such as the outdoor side.

[0061] The first hooking piece 411 and the first hooking part 421 can hook together on the indoor side of the sliding window, while the second hooking piece 412 and the second hooking part 422 can hook together on the outdoor side of the sliding window. Therefore, when the sliding window is closed, both the indoor and outdoor sides can be sealed, effectively sealing the contact gap between the movable sash 2 and the fixed sash 3, and reducing the entry of dust, sand, and other impurities into the space between the movable sash 2 and the fixed sash 3, thus minimizing the risk of damage to the profiles or poor sealing caused by impurities.

[0062] Similarly, to further improve sealing performance, in some embodiments, sealing components can be incorporated to further enhance the sealing performance of the pull-out window. Figure 6 In the illustrated embodiment, the sealing assembly includes at least one first seal 413 and an equal number of second seals 423. The first seal 413 is disposed between the first hook 411 and the second hook 412, and the second seal 423 is disposed between the first hook portion 421 and the second hook portion 422.

[0063] After hooking parts 41 and 42 are installed on the indoor and outdoor sides respectively, a sealing component can be installed in the middle of the profile. By increasing the number of first sealing parts 413 and second sealing parts 423, a multi-level sealing structure is formed between the movable fan 2 and the fixed fan 3. The multi-level sealing structure can better prevent dust from passing through.

[0064] The sealing effect of the first sealing element 413 and the second sealing element 423 is not limited to the following: the first sealing element 413 is a sealing element, and the second sealing element 423 is provided with a sealing strip. The sealing effect of the sliding window can be further improved by the pressing action of the sealing element and the sealing strip. In addition, the first sealing element 413 and the second sealing element 423 can also adopt other structural forms to achieve sealing, which are not limited in this application.

[0065] Obviously, when multiple hooks 41, hook portions 42, and sealing components are provided between the movable sash 2 and the fixed sash 3, the positions of each structural component should facilitate the closing of the pull-up window. For example, the first sealing component 413 is provided on a protrusion of the movable sash 2, forming a sequentially elongated structure with the first hook 411 and the second hook 412. That is, the first hook 411 is the longest, the first sealing component 413 is next, and the second hook 412 is the shortest. Correspondingly, the second sealing component 423 also maintains the above-described form with the first hook portion 421 and the second hook portion 422. Such a structure ensures that the components do not obstruct each other during the movement of the movable sash 2, and can sequentially enter the corresponding hook portion 42 or achieve a seal with the corresponding sealing component.

[0066] In addition to adding the hook-locking assembly 4 between the indoor and outdoor sides, other forms of sealing devices can also be added between the indoor and outdoor sides. For example, in some embodiments, the pull-up window also includes a flexible seal, which can be made of soft materials such as rubber, foam, or plastic. The flexible seal can deform under the pressure of the movable sash 2 and the fixed sash 3 after the pull-up window is closed, and seal the contact gap.

[0067] Unlike pull-out windows with directly installed flexible seals, in this embodiment, the flexible seal is positioned between the indoor and outdoor sides. This allows for sealing on the indoor side through a hooking action between the first hook member 411 and the first hook portion 421, and simultaneously on the outdoor side through a hooking action between the second hook member 412 and the second hook portion 422. A flexible material is then used to seal between the indoor and outdoor sides. Since both the indoor and outdoor sides are sealed first by the hook-locking assembly 4, the probability of the flexible seal directly contacting the outdoor environment is reduced. This mitigates the rapid aging and damage of the flexible seal due to environmental factors, extends its service life, and ultimately improves the sealing performance of the pull-out window.

[0068] To achieve better sealing performance, an extension structure can be provided on the hook member 41 and / or the hook part 42. This extension structure can misalign the hooking position of the hook member 41 and the hook part 42 with the contact gap between the movable fan 2 and the fixed fan 3, thereby extending the path for air and dust to enter and improving sealing performance. That is, Figure 7 As shown, in some embodiments, the first hook member 411 includes a hook part 4111 and a first fixing plate 4112. The hook part 4111 is connected to the profile of the movable fan 2 through the first fixing plate 4112. The first hook part 421 is disposed on the profile of the fixed fan 3 or on the mullion profile.

[0069] The hook part 4111 can be set at a position that protrudes from the profile of the movable sash 2 through the first fixing plate 4112. When the movable sash 2 moves to the position where the sliding window is closed, the first fixing plate 4112 can cover part of the profile side of the fixed sash 3 on the indoor side, so that the hooking position of the first hook part 411 and the first hook part 421 is located at a position lower than the contact gap between the movable sash 2 and the fixed sash 3. This not only blocks the direct flow of air in the gap using the first fixing plate 4112, but also extends the path of airflow and improves the sealing performance.

[0070] Meanwhile, when the movable fan 2 is in the position to close the pull-up window, the first fixing plate 4112 is close to the indoor side of the fixed fan 3, which can restrict the movable fan 2 from flipping to the indoor side. At this time, the first fixing plate 4112 can achieve the same function as the support component 5.

[0071] Similarly, the second hook member 412 and the second hook part 422 can also adopt an extended structure to offset the hooking position from the contact gap, thereby improving the sealing performance. However, to achieve better sealing performance and facilitate the hooking and unhooking of the hook member 41 and the hook part 42, the hooking positions of the second hook member 412 and the second hook part 422 should not be located on the same side of the contact gap as the first hook member 411 and the first hook part 421; they should also be staggered. That is, as... Figure 8 As shown, in some embodiments, the second hook part 422 includes a hook part 4221 and a second fixing plate 4222; the hook part 4221 is connected to the profile of the fixed fan 3 through the second fixing plate 4222, and the second hook member 412 is disposed on the profile of the movable fan 2.

[0072] As can be seen, in the above embodiment, the first hook member 411 and the first hook part 421 form a hook below the contact gap, and the second hook member 412 and the second hook part 422 form a hook above the contact gap. This structure can form protruding structures on the movable sash 2 and the fixed sash 3 respectively, facilitating the opening and closing of the movable sash 2. At the same time, the first fixing plate 4112 and the second fixing plate 4222 can respectively cover the contact gap on the indoor and outdoor sides, improving the sealing performance. In addition, the first fixing plate 4112 and the second fixing plate 4222 can also cover the contact gap and the profile components around the contact gap, so that the hook member 41 and the hook part 42 on both the indoor and outdoor sides are covered, improving the overall aesthetics of the pull-out window.

[0073] As can be seen from the above technical solutions, the above embodiments can form multiple hooking points in the contact area of ​​the movable sash 2 and the fixed sash 3 by using multiple hooking parts 41 and hooking parts 42. The multiple hooking points can further improve the sealing performance of the movable sash 2 and the fixed sash 3 and enhance the aesthetics while satisfying the opening and closing of the pull-up window.

[0074] When the locking assembly 4 is selectively engaged, the movable sash 2 will slightly rotate around the engagement point when subjected to external wind pressure. The further away from the engagement point, the more severe the rotation between the movable sash 2 and the locking assembly 4, resulting in poorer sealing performance between the locking assembly 4 and the frame of the movable sash 2, and a decrease in the overall window performance.

[0075] Therefore, as Figure 9 As shown, in some embodiments, the pull-up window provided in this application further includes a support component 5, which includes a blocking part 51 and a blocked part 52. The blocking part 51 and the blocked part 52 can selectively provide support. The blocking part 51 is disposed on the fixed sash 3, the frame 1, or the mullion profile. The blocked part 52 is disposed on the frame profile of the movable sash 2 on the side closer to the interior.

[0076] By setting the support component 5, when the movable sash 2 is closed and the hook-locking component 4 is selectively hooked, the blocking part 51 and the blocked part 52 cooperate to prevent the movable sash 2 from rotating around the hook-locking part when subjected to wind pressure, thereby enhancing the sealing performance between the hook-locking component 4 and the frame of the movable sash 2 and improving the overall window sealing.

[0077] Figure 9The diagram shows a case where one set of hook-locking components 4 and one set of support components 5 are provided. In this embodiment, the hook-locking components 4 provide hook-locking and sealing, while the support components 5 provide protection against the movement of the movable fan 2 rotating inward along the hook-locking part as an axis due to wind pressure. It should be noted that the longer the blocked part 52 is, the better its sealing and support performance should be (the larger the contact area with the blocking part 51), but it should not exceed the range of the blocking part 51.

[0078] To improve the sealing effect, the number of hook-locking components 4 and support components 5 can be increased. That is, in some embodiments, at least two sets of hook-locking components 4 and at least one set of support components 5 are provided, so that multiple sets of hook-locking components 4 and support components 5 can form a multi-level hook-locking and multi-level support effect, thereby improving the sealing performance.

[0079] like Figure 10 As shown, in some embodiments, the blocking part 51 includes a blocking surface 511, and the blocked part 52 includes a blocked surface 521; when the movable fan 2 is closed, the blocking surface 511 is in contact with the blocked surface 521; when the movable fan 2 is open, the blocking surface 511 and the blocked surface 521 are separated. The contact or separation of the blocking surface 511 and the blocked surface 521 according to the open state of the window transmits the force arm and improves the sealing effect.

[0080] Because the lever arm between the locking part and the sealing strip is relatively long at the hook-locking position on the indoor side, the hook point will become a fulcrum of force when subjected to wind pressure, causing a rotational tendency at the lower edge of the movable fan 2, reducing the sealing effect. Therefore, in some embodiments, the support component 5 can be located on the indoor side of the hook-locking component 4, that is, the support component 5 is located on the opening direction side of the hook-locking component 4; the hook-locking component 4 can be located closer to the outdoor side to improve the sealing effect. That is, the closer the hook position is to the outside, the smaller the lever arm between the locking position and the sealing position, and the better the sealing effect when the movable fan 2 is subjected to external wind pressure. At the same time, the indoor support point can also be a hook-locking structure, in which case the indoor locking structure also acts as a support point.

[0081] In some embodiments, by Figure 11 As shown, the blocking part 51 includes a first blocking part 551 and a second blocking part 552; the blocked part 52 includes a first blocked part 561 and a second blocked part 562; the first blocking part 551 and the first blocked part 561 form a blocking state; the second blocking part 552 and the second blocked part 562 form a blocking state. Through the first blocking part 551, the second blocking part 552, the first blocked part 561, and the second blocked part 562, at least two support points can be formed, improving the support effect and enhancing the sealing performance.

[0082] It should be noted that, in this embodiment, forming a blocking state means that part or all of the first blocking part 551 blocks part or all of the first blocked part 561, and part or all of the second blocking part 552 blocks part or all of the second blocked part 562.

[0083] In some embodiments, the blocking surface 511 is integrally formed with the hook portion 42, and the blocked surface 521 is integrally formed with the hook member 41, which is used to improve stability, reduce the number of components installed, and improve the sealing effect.

[0084] In some embodiments, see Figure 6 The support component 5 can also be integrated with the hook-locking component 4. For example, when the hook-locking component 4 includes a first hook 411 and a first hook 421, the support component 5 can also be formed at the root of the first hook 411 or at other positions. In this case, the blocking part 51 and the blocked part 52 form a blocking state, which also provides a support effect.

[0085] In some embodiments, see Figure 12 The blocking part 51 and the blocked part 52 can also be designed to not be in direct contact. That is, when the first hook 411 and the first hook 421 are hooked, there is a gap between the blocking part 51 and the blocked part 52. When the movable fan 2 and the fixed fan 3 move relative to each other, the blocking part 51 then contacts the blocked part 52 and forms a blocking state, thereby providing a support effect.

[0086] It should be noted that, in the embodiments of this application, the blocking support state may include the blocking state formed between the blocking part 51 and the blocked part 52, and also the state in which there is a gap between the two.

[0087] For the movable sash 2 and fixed sash 3 of the pull-out window, materials such as aluminum alloy, PVC, and stainless steel can be used. When these materials come into contact, the friction coefficient is relatively high, which is not conducive to hooking. Furthermore, long-term opening and closing will cause wear on the profiles, limiting their service life. Therefore, to facilitate hooking and extend the service life of the profiles, in some embodiments, the hooking and locking assembly 4 also includes a self-lubricating element 43.

[0088] like Figure 13As shown, the self-lubricating component 43 can be disposed within the hook portion 42 or on the hook portion 41. The coefficient of sliding friction between the self-lubricating component 43 and the hook portion 41 or the hook portion 42 is less than the coefficient of sliding friction between the hook portion 41 and the hook portion 42. For example, the self-lubricating component 43 can be made of self-lubricating materials, including solid lubricants, solid lubricating composite materials, polytetrafluoroethylene (PTFE), coating materials, and solid lubricating alloys. Among them, solid lubricants, such as graphite and molybdenum disulfide, can play a lubricating role between friction surfaces through a layered structure. Solid lubricating composite materials are composed of solid lubricants and base materials, such as graphite-filled polymers or metal-based composite materials. Polytetrafluoroethylene is a material with a low coefficient of friction and excellent lubricity. Coating materials, such as diamond coating (DLC), hexametaphosphate coating (HAP), ion carburizing, etc., can form a lubricating layer to provide self-lubricating properties. Solid lubricating alloys are materials composed of a metal matrix and a lubricating phase. The lubricating phase can be a low-melting-point metal or composite that can play a lubricating role between metal matrices.

[0089] The self-lubricating component 43 can replace the inner wall of the hook portion 42 in contacting the hook member 41 during the process of the hook member 41 entering the hook portion 42, or replace the hook member 41 in contacting the inner wall of the hook portion 42, so that the hook member 41 does not directly contact the hook portion 42, reducing the friction during the process of entering the hook portion 42. Furthermore, the self-lubricating component 43 can be detachably connected to the hook portion 42, that is, after the self-lubricating component 43 wears to a certain extent, it can be replaced to reduce direct wear between the movable sash 2 and the fixed sash 3 profiles, extending the service life of the window frame profiles.

[0090] Therefore, as Figure 14 As shown, in some embodiments, the bottom of the hook portion 42 is provided with a receiving groove 424, and the self-lubricating component 43 includes a connecting portion 431 and a lubricating portion 432. The lubricating portion 432 is connected to the connecting portion 431, and the connecting portion 431 is disposed within the receiving groove 424. The receiving groove 424 can be a rectangular groove structure disposed within the hook portion 42, and the connecting portion 431 can be a rectangular plate structure adapted to the receiving groove 424, i.e., the connecting portion 431 can be inserted into the receiving groove 424. One side of the connecting portion 431 is abutted against one side of the receiving groove 424, and the other side of the connecting portion 431 is connected to the lubricating portion 432.

[0091] The insertion relationship between the receiving groove 424 and the connecting part 431 allows for a detachable connection between the self-lubricating component 43 and the hook part 42, enabling the self-lubricating component 43 to be replaced after prolonged use and wear. Alternatively, the self-lubricating component 43 can be a structural component where the connecting part 431 and the lubrication part 432 are integrally formed, meaning both are made of materials with a low coefficient of sliding friction, thus reducing manufacturing complexity while still meeting lubrication performance requirements.

[0092] In some embodiments, the hook member 41 and the hook portion 42 are strip-shaped structural members continuously distributed along the extension direction of the profile, or the hook member 41 and the hook portion 42 are segmented structural members spaced apart along the extension direction of the profile. Wherein, for example... Figure 1 As shown, the profile extension direction is the direction of the profile on the side of the movable sash 2 closest to the fixed sash 3 when the pull-up window is in the closed state. That is, the hook-locking assembly 4 can be installed along the entire edge or in segments.

[0093] Similarly, the self-lubricating component 43 is a strip-shaped structural component covering the hook component 41 or the hook portion 42, or the self-lubricating component 43 is a segmented structural component spaced apart in the hook portion 42. That is, the self-lubricating component 43 can be set along the entire edge or in segments. The specific setting method can be determined according to the application environment of the pull-up window and the specific profile structure of the pull-up window.

[0094] For example, since there are gaps between each segment of the segmented self-lubricating component 43, the sealing performance will be reduced to some extent. Therefore, in areas with low average annual temperature and frequent sandstorms, a strip structure covering the hook part 42 can be used as the self-lubricating component 43 to obtain better sealing performance.

[0095] For example, when the hook member 41 and the hook part 42 are segmented structural members spaced apart along the extension direction of the profile, the self-lubricating member 43 is a segmented structural member spaced apart in the hook member 41 or the hook part 42, and the number of segments, the interval between segments, and the length of each segment of the hook member 41 and the hook part 42 are adapted to the number of segments, the interval between segments, and the length of each segment of the self-lubricating member 43, that is, the number of segments is the same, the interval between segments is equal, and the length of each segment of the hook member 41 and the hook part 42 is greater than or equal to the length of each segment of the self-lubricating member 43.

[0096] By using segmented structural components, the amount of window frame material used can be reduced, and the molding process for the material can be simplified. Furthermore, the segmented structural components allow for more targeted adaptation to specific environments by setting segment positions and installing hook-and-seal elements 4 in areas prone to air leakage. It should be noted that when the hook-and-seal element 41 and hook-and-seal element 42 are segmented structural components spaced apart along the extension direction of the profile, both the hook-and-seal element 41 and hook-and-seal element 42 can be segmented structures, or the hook-and-seal element 41 can be segmented while the hook-and-seal element 42 is a strip structure.

[0097] For example, the self-lubricating element 43 is a roller assembly disposed on the hook member 41 or the hook portion 42. By replacing sliding friction with rolling friction of the roller assembly, the friction force can be further reduced and the lubrication effect improved.

[0098] In addition to the self-lubricating component 43 mentioned in this embodiment, in some other embodiments, the contact position between the hook component 41 and the hook portion 42 can also be set as a sliding friction structure, which will not be elaborated here.

[0099] Based on the pull-up window provided in the above embodiments, a hook-locking component is also provided in some embodiments of this application, applied to the pull-up window described in the above embodiments. The pull-up window includes: a frame 1, a movable sash 2, and a fixed sash 3; the movable sash 2 is movably connected to the frame 1; the fixed sash 3 is fixedly connected to the frame 1. The hook-locking component 4 includes a hook member 41 and a hook part 42, which can be selectively hooked together; one of the hook member 41 and the hook part 42 is disposed on the movable sash 2, and the other of the hook member 41 and the hook part 42 is disposed on the fixed sash 3.

[0100] As can be seen from the above technical solutions, the above embodiments provide a pull-out window and a hook-and-lock assembly. The hook-and-lock assembly 4 is disposed between the movable sash 2 and the fixed sash 3 of the pull-out window, and is used to seal the contact gap between the movable sash 2 and the fixed sash 3 when the pull-out window is in the closed state. The hook-and-lock assembly 4 includes a hook member 41 and a hook part 42, and the hook member 41 and the hook part 42 can be selectively hooked together; one of the hook member 41 and the hook part 42 is disposed on the movable sash 2, and the other of the hook member 41 and the hook part 42 is disposed on the fixed sash 3. Through the hook-and-lock relationship between the hook member 41 and the hook part 42 in the hook-and-lock assembly 4, the movable sash and the mullion or the movable sash and the fixed sash can be locked together, forming a multi-level locking effect. The support component 5 includes a blocking part 51 and a blocked part 52. When the hook-locking component 4 is selectively engaged, the movable sash 2 will slightly rotate around the hook-locking part when subjected to external wind pressure. The further away from the hook-locking part, the more severe the rotation between the movable sash 2 and the hook-locking component 4, resulting in poor sealing performance between the hook-locking component 4 and the frame of the movable sash 2, and a decrease in the overall window performance. When the movable sash 2 is closed and the hook-locking component 4 is selectively engaged, the blocking part 51 cooperates with the blocked part 52 to prevent the movable sash 2 from rotating around the hook-locking part when subjected to wind pressure. Furthermore, by setting the hook 41 and the hook-locking part 42, the movable sash 2 and the fixed sash 3 can maintain a sealed state through rigid materials, reducing the impact of external forces and alleviating the problem of poor sealing performance of the pull-up window.
