Description

Technical Field

[0001] The present application relates to the technical field of building profiles, and in particular to a lifting window and a hook locking assembly. Background Art

[0002] A sliding window is a window that can be opened and closed by sliding a window sash. The sliding window may include multiple window sashes, and the multiple window sashes may cover the entire window. Among them, the window sashes that can slide are called movable sashes, and the window sashes that cannot slide are called fixed sashes. The movable sash and fixed sash of the sliding window may include a profile frame and fillers such as glass arranged on the profile frame to block the indoor and outdoor environments.

[0003] Since the movable sash and the fixed sash can move relative to each other and are affected by the manufacturing process, the movable sash needs to be sealed with the ventilation part by a seal when it is closed. In order to improve the sealing effect, a sealing component can be provided on the movable sash and the ventilation part. For example, a sealing strip can be provided at the contact gap between the movable sash and the fixed sash. When the lifting window is closed, the sealing strip can be squeezed by the movable sash and the profile frame of the ventilation part to produce elastic deformation, thereby sealing the contact gap between the movable sash and the ventilation part.

[0004] However, the sealing component itself is elastic, and a reaction force will be generated when the movable fan is closed. In addition, due to the effect of outdoor wind pressure on the movable fan, the sealing effect is poor after the movable fan is closed, reducing the air tightness and thermal insulation performance of the sliding window.

[0039] In order to make the purpose, technical solutions and advantages of some embodiments of the present application clearer, the technical solutions of some embodiments of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0040] It should be noted that the brief description of terms in some embodiments of the present application is only for the convenience of understanding the implementation methods described below, and is not intended to limit the implementation methods of some embodiments of the present application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0041] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0042] In the present application embodiment, Figure 1 As shown, the lifting window includes a frame 1, a movable sash 2 and a fixed sash 3. The frame 1 is installed on the window wall of the building, and can be a rectangular frame structure or a Japanese-shaped structure. When the frame 1 is a Japanese-shaped structure, the frame 1 is also provided with a middle stile profile. The movable sash 2 and the fixed sash 3 are both installed in the frame 1, but the fixed sash 3 is fixedly installed in the frame 1, and the movable sash 2 is movably installed in the frame 1. The movable sash 2 and the fixed sash 3 can be rectangular frame structures, and barrier materials such as glass can be installed on the movable sash 2 and the fixed sash 3. When the movable sash 2 is in a closed state, the movable sash 2 and the fixed sash 3 can completely close the frame 1 to seal the space inside the building.

[0043] like Figure 2 As shown, the fixed sash 3 can be set in the area enclosed by the frame 1, on the side where the window does not need to be opened for ventilation, while the movable sash 2 can be set on the side where the window needs to be opened for ventilation. For example, for a vertically open and close sliding window, the fixed sash 3 is fixed to the lower part of the frame 1, and the movable sash 2 is set to the upper part of the frame 1, and the movable sash 2 can move in the vertical direction. When the window needs to be opened for ventilation, the movable sash 2 is moved down to open the upper area of ​​the sliding window for ventilation, and when the window does not need to be opened for ventilation, the movable sash 2 is moved up to close the upper area of ​​the sliding window.

[0044] In some embodiments, Figure 3 , Figure 4As shown, in order to facilitate the movement of the movable sash 2, a slide 11 for assisting the movement of the movable sash 2 may be provided on the frame 1. For vertical opening and closing type lifting windows, the slide 11 may be provided on two columns of the frame 1. The movable sash 2 is provided with a sliding shaft 21, and the sliding shaft 21 can move in the slide 11. For example, for vertical opening and closing type lifting windows, an S-shaped slide 11 is provided on the two columns 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, and the sliding shaft 21 protrudes from the side profile of the movable sash 2. After assembly, the sliding shaft 21 can enter the slide 11 and move relative to the slide 11, so that the sliding shaft 21 can drive the entire movable sash 2 to move along the slide 11 to realize the opening and closing of the lifting window.

[0045] During the opening and closing process of the lifting window, the movable sash 2 can be driven by the window machine 6, wherein the window machine 6 can be arranged on the top of the frame, or can be arranged inside the frame profile of the movable sash 2 or the fixed sash 3. Figure 1 As shown, in some embodiments, the window machine 6 includes a driving motor, a transmission component, a traction rope, and a lifting pulley set. The driving motor is connected to one end of the traction rope through the transmission component, and the other end of the traction rope passes through the lifting pulley set and is connected to the movable sash 2. During the opening process of the lifting window, the driving motor rotates forward, and the traction rope is loosened through the transmission component, so that the movable sash 2 moves down along the slideway to increase the opening of the lifting window; during the closing process of the lifting window, the driving motor reverses, and the traction rope is tightened through the transmission component, so that the movable sash 2 moves up along the slideway to reduce the opening of the lifting window.

[0046] In some embodiments, for a vertically opened and closed lifting window, when the movable sash 2 moves to the highest position, the lifting window is in a completely closed state, and the lifting window should meet the sealing requirements of the building. 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 lifting window, so it is necessary to add a sealing device to the movable sash 2 and the fixed sash 3. The sealing device can block, block and press the contact gap between the movable sash 2 and the fixed sash 3 to improve the sealing performance of the lifting window.

[0047] For example, the sealing device can be a fixed plate arranged 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 airflow path, so that air and dust are not easy to enter the indoor environment through the contact gap.

[0048] However, since the fixed plate only covers the contact gap, there is no direct contact or close contact between the fixed plate and the movable fan 2 or the fixed fan 3, resulting in a gap between the fixed plate and the movable fan 2 or the fixed fan 3. Therefore, after long-term use, there is still a problem of poor sealing. To this end, in some embodiments, a close contact sealing device can be used to further improve the sealing effect.

[0049] For example, the sealing device may also include a sealing strip arranged at the contact gap position between the movable sash 2 and the fixed sash 3. When the sliding window is in the closed state, the sealing strip can be elastically deformed by the extrusion of the profile frame of the movable sash 2 and the fixed sash 3 to close the contact gap between the movable sash 2 and the fixed sash 3.

[0050] However, the sealing component itself is elastic, and a reaction force will be generated when the movable fan is closed. In addition, due to the effect of outdoor wind pressure on the movable fan, the sealing effect is poor after the movable fan is closed, reducing the air tightness and thermal insulation performance of the sliding window.

[0051] Based on the problem of low sealing performance of the above-mentioned lifting window, in some embodiments of the present application, a lifting window is further provided, and the lifting window can be the lifting window structure provided in the above-mentioned embodiment, that is, the lifting window can include: a frame 1, a movable sash 2 and a fixed sash 3, and the movable sash 2 is movably connected to the frame 1 to realize the opening and closing of the entire window, and the fixed sash 3 is fixedly connected to the frame 1 and cooperates with the movable sash 2 to close the lifting window. In order to improve the sealing performance of the lifting window, the lifting window also includes a hook locking component 4.

[0052] Among them, Figure 5 As shown, the hook locking assembly 4 includes a hook member 41 and a hook portion 42, and the hook member 41 and the hook portion 42 can be selectively hooked. One of the hook member 41 and the hook portion 42 is arranged on the movable sash 2, and the other of the hook member 41 and the hook portion 42 is arranged on the middle sash profile of the fixed sash 3 or the frame 1. That is, the hook member 41 can be arranged on the movable sash 2, and the hook portion 42 is arranged on the middle sash profile of the fixed sash 3 or the frame 1. When the hook member 41 is arranged on the middle sash profile of the fixed sash 3 or the frame 1, the hook portion 42 is arranged on the movable sash 2.

[0053] The hook member 41 and the hook portion 42 are two mating parts that can be hooked to each other, and the specific shapes can be set according to the profile structure. For example, the hook member 41 can be a hook-shaped structure provided on the protruding profile body, and the hook portion 42 can be a groove-shaped structure provided on the recessed profile body. The setting positions of the hook member 41 and the hook portion 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, the hook member 41 and the hook portion 42 should be arranged on the profile frame where the movable sash 2 and the fixed sash 3 are close to each other when the lifting window is in a closed state. For example, for a lifting window that opens and closes vertically, 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 the hook member 41 can be arranged on the lower frame of the movable sash 2, and the hook portion is arranged on the upper frame of the fixed sash 3.

[0054] After the hooking, the hooking member 41 and the hooking part 42 are hooked, it should be conducive to achieving the sealing of the window. To this end, the hooking member 41 and the hooking part 42 can be provided with contact surfaces respectively, and the contact surfaces can contact each other when the window is lifted and closed, and form a certain pressing force. The pressing force can make the material of the hooking member 41 or the hooking part 42 produce a certain degree of elastic deformation, thereby improving the sealing. At the same time, the contact surfaces of the hooking member 41 and the hooking part 42 can be tilted in the same direction, so that the hooking member 41 can enter the hooking part 42 during the closing process of the movable door 2.

[0055] For example, a fixed plate extends from the lower frame profile of the movable sash 2, and the side of the fixed plate close to the indoor is a plane, and the side close to the outdoor is provided with a hook-shaped structure to form a hook member 41. Correspondingly, a groove is provided on the side of the upper frame of the fixed sash, and the cross-section of the groove is L-shaped to form a hook portion 42. The hook-shaped structure of the hook member 41 and the L-shaped groove of the hook portion 42 are both provided with inclined surfaces. In the process of closing the lifting window, the movable sash 2 first moves upward, and then moves obliquely upward along the slide 11, then the hook member 41 can move with the movable sash 2, so that the hook-shaped structure enters the hook portion 42. Moreover, as the movable sash 2 continues to move obliquely upward, the inclined surfaces on the hook member 41 and the hook portion 42 contact each other and generate a certain pressing force, thereby closing the contact gap between the movable sash 2 and the fixed sash 3 to achieve a sealing effect.

[0056] Obviously, one of the above-mentioned hook member 41 and hook portion 42 is arranged on the movable fan 2, and the other of the hook member 41 and hook portion 42 is arranged on the fixed fan 3. This refers to the hook member 41 and hook portion 42 that cooperate with each other in the same group of hook and locking components 4. In some embodiments, the lifting window may include multiple groups of hook and locking components 4, and the multiple groups of hook and locking components 4 may be respectively arranged at multiple positions of the movable fan 2 and the fixed fan 3.

[0057] The hooking members 41 and the hooking parts 42 in different groups of hooking and locking components 4 can be respectively arranged on the movable leaf 2 and the fixed leaf 3 according to needs and specific shapes. For example, the hooking members 41 in the first group of hooking and locking components 4 are arranged on the movable leaf 2, while the hooking members 41 in the second group of hooking and locking components 4 can be arranged on the fixed leaf 3. Correspondingly, the hooking parts 42 in the first group of hooking and locking components 4 are arranged on the fixed leaf 3, while the hooking parts 42 in the second group of hooking and locking components 4 can be arranged on the movable leaf 2.

[0058] It can be seen from the above technical solution that by setting the hook member 41 and the hook part 42, a sealing method of selective hooking can be provided between the movable sash 2 and the fixed sash 3 when the lifting window is closed. Since the hook member 41 and the hook part 42 can be made of the same material as the profile or a material with the same strength, the hook member 41 and the hook part 42 are affected by the environment to the same extent as the profile, which alleviates the problem of poor sealing caused by premature aging of the sealing device. In addition, the hook member 41 and the hook part 42 can be directly designed as a structure integrally formed with the movable sash 2 or the fixed sash 3, simplifying the assembly process, reducing the assembly gap generated during the assembly process, and improving the sealing performance of the lifting window.

[0059] In the above embodiment, the hook locking assembly 4 can close the contact gap through the hooking action of the hook member 41 and the hook portion 42, and the more the hook members 41 and the hook portions 42 are, the more areas of hooking action are formed between the movable sash 2 and the fixed sash 3, and the more obvious the improvement of the sealing effect of the lifting window is. Therefore, the sealing performance can be further improved by increasing the number of hook members 41 and the hook portions 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 arranged on one side of the lifting window, such as the indoor side, and the second hook member 412 and the second hook portion 422 are arranged on a side of the lifting window away from the first hook member 411, such as the outdoor side.

[0061] The first hooking member 411 and the first hooking portion 421 can produce a hooking effect on the indoor side of the lifting window, and the second hooking member 412 and the second hooking portion 422 can produce a hooking effect on the outdoor side of the lifting window. When the lifting window is in a closed state, both the indoor side and the outdoor side can have a sealing effect, which can not only seal the contact gap between the movable fan 2 and the fixed fan 3, but also reduce the entry of impurities such as dust, sand and gravel into the space between the movable fan 2 and the fixed fan 3, thereby reducing the problem of profile damage or poor sealing caused by impurities.

[0062] Similarly, in order to further improve the sealing performance, in some embodiments, the sealing performance of the lifting window can be further improved by providing a sealing component. Figure 6 In the illustrated embodiment, the sealing assembly includes at least one first sealing member 413 and the same number of second sealing members 423 as the first sealing members 413. The first sealing member 413 is disposed between the first hook member 411 and the second hook member 412, and the second sealing member 423 is disposed between the first hook portion 421 and the second hook portion 422.

[0063] That is, after the hook member 41 and the hook portion 42 are respectively arranged on the indoor side and the outdoor side, a sealing assembly can also be arranged in the middle position of the profile. By increasing the number of first seals 413 and second seals 423, a multi-stage sealing structure is formed between the movable fan 2 and the fixed fan 3. The multi-stage sealing structure can better prevent dust from passing through.

[0064] The form in which the first seal 413 and the second seal 423 achieve the sealing effect is not limited to that the first seal 413 is a seal and the second seal 423 is provided with a sealing strip, and the sealing effect of the pull-up window can be further improved by the compression effect of the seal and the sealing strip; in addition, the first seal 413 and the second seal 423 can also adopt other structural forms to cooperate to achieve sealing, which is not limited in the present application.

[0065] Obviously, when multiple hooks 41, hook portions 42 and sealing components are arranged between the movable sash 2 and the fixed sash 3, the arrangement position of each structural member should be convenient for lifting and closing the window. For example, the first sealing member 413 is arranged on a boss of the movable sash 2, and forms a structure that is elongated in sequence with the first hook 411 and the second hook 412. That is, the first hook 411 is the longest, the first sealing member 413 is the second, and the second hook 412 is the shortest. Matchingly, the second sealing member 423 also maintains the above form with the first hook portion 421 and the second hook portion 422. Such a structure can prevent the components from causing obstructions to each other during the movement of the movable sash 2, and can enter the corresponding hook portion 42 in sequence or seal with the corresponding sealing member.

[0066] In addition to adding a hook locking assembly 4 between the indoor side and the outdoor side, other forms of sealing devices may be added between the indoor side and the outdoor side. For example, in some embodiments, the lifting window further includes a flexible seal, which may be made of soft materials such as rubber, foam, and plastic. After the lifting window is closed, the flexible seal may be squeezed by the movable sash 2 and the fixed sash 3 to deform and seal the contact gap.

[0067] Different from the lifting window in which the flexible seal is directly provided, in this embodiment, the flexible seal is provided between the indoor side and the outdoor side, and a hooking seal can be generated between the first hooking member 411 and the first hooking portion 421 on the indoor side, and a hooking seal can be generated between the second hooking member 412 and the second hooking portion 422 on the outdoor side, and then the indoor side and the outdoor side are sealed by the flexible material. Since both the indoor side and the outdoor side are first sealed by the hook locking assembly 4, the probability of the flexible seal directly contacting the outdoor environment can be reduced, thereby alleviating the rapid aging and damage of the flexible seal due to environmental factors, extending the service life of the flexible seal, and thus improving the sealing performance of the lifting window.

[0068] In order to obtain better sealing performance, an extension structure may be provided on the hook member 41 and / or the hook portion 42. The extension structure may cause the position where the hook member 41 and the hook portion 42 are hooked to be misaligned with the contact gap between the movable fan 2 and the fixed fan 3, thereby extending the path for air, dust, etc. to enter and improving the sealing performance. Figure 7 As shown, in some embodiments, the first hook member 411 includes a hook portion 4111 and a first fixed plate 4112, the hook portion 4111 is connected to the profile of the movable fan 2 through the first fixed plate 4112; the first hook portion 421 is arranged on the profile of the fixed fan 3 or on the middle beam profile.

[0069] Among them, the hooking part 4111 can be set at a position relative to the protruding movable fan 2 profile through the first fixed plate 4112. When the movable fan 2 moves to the position to close the lifting window, the first fixed plate 4112 can cover a part of the profile side of the fixed fan 3 on the indoor side, so that the hooking position of the first hook member 411 and the first hooking part 421 is located below the contact gap between the movable fan 2 and the fixed fan 3. Not only can the first fixed plate 4112 be used to block the direct flow of air in the gap, but also the path for the airflow to enter can be extended to improve the sealing performance.

[0070] At the same time, when the movable fan 2 is moved to the position to close the lifting window, the first fixed plate 4112 is close to the fixed fan 3 close to the indoor side, which can limit the movable fan 2 from flipping toward the indoor side. At this time, the first fixed plate 4112 can achieve the same function as the support assembly 5.

[0071] Similarly, the second hooking member 412 and the second hooking portion 422 can also adopt an extended structure to make the hooking position offset from the contact gap to improve the sealing performance. In order to obtain better sealing performance and facilitate the hooking and separation of the hooking member 41 and the hooking portion 42, the hooking position of the second hooking member 412 and the second hooking portion 422 should not be located on the same side of the contact gap as the first hooking member 411 and the first hooking portion 421, and should also be offset. Figure 8 As shown, in some embodiments, the second hook portion 422 includes a hook portion 4221 and a second fixing plate 4222 ; the hook portion 4221 is connected to the profile of the fixed fan 3 through the second fixing plate 4222 , and the second hook member 412 is arranged on the profile of the movable fan 2 .

[0072] It can be seen that in the above embodiment, the first hook member 411 and the first hook portion 421 form a hook below the contact gap, and the second hook member 412 and the second hook portion 422 form a hook above the contact gap. Such a structure can form a convex structure on the movable fan 2 and the fixed fan 3, respectively, to facilitate the opening and closing of the movable fan 2. At the same time, the first fixed plate 4112 and the second fixed plate 4222 can respectively block the contact gap on the indoor side and the outdoor side to improve the sealing performance. In addition, the first fixed plate 4112 and the second fixed plate 4222 can also block the contact gap and the profile parts around the contact gap, so that the hook member 41 and the hook portion 42 on the indoor side and the outdoor side are blocked, thereby improving the overall aesthetics of the lifting window.

[0073] It can be seen from the above technical solution that the above embodiment can form multiple hooking points in the contact area of ​​the movable fan 2 and the fixed fan 3 through multiple hooking parts 41 and hooking portions 42. The use of multiple hooking points can further improve the sealing performance of the movable fan 2 and the fixed fan 3 while meeting the opening and closing of the lifting window, and enhance the aesthetics.

[0074] When the hook and lock assembly 4 is selectively hooked, the movable sash 2 will slightly rotate around the hooking position as the axis under the action of the wind pressure when the movable sash 2 is subjected to the external wind pressure. The farther away from the hooking position, the more serious the rotation between the movable sash 2 and the hook and lock assembly 4, resulting in poor sealing performance between the hook and lock assembly 4 and the frame of the movable sash 2, and the performance of the entire window is reduced.

[0075] Therefore, if Fig. 9 As shown, in some embodiments, the lifting window provided in the present application also includes a supporting assembly 5, the supporting assembly 5 includes a blocking portion 51 and a blocked portion 52, and the blocking portion 51 and the blocked portion 52 can selectively realize support; the blocking portion 51 is arranged on the fixed fan 3, the frame 1 or the middle stile profile; the blocked portion 52 is arranged on the frame profile of the movable fan 2 close to the indoor side.

[0076] By providing the support assembly 5, when the movable fan 2 is closed and the hook-lock assembly 4 is selectively hooked, the blocking portion 51 can cooperate with the blocked portion 52 to prevent the movable fan 2 from rotating around the hooking portion when subjected to wind pressure, thereby enhancing the sealing performance between the hook-lock assembly 4 and the frame of the movable fan 2 and improving the sealing of the entire window.

[0077] Fig. 9What is shown is a situation where one group of hook locking components 4 is provided, and one group of supporting components 5 is provided. In this embodiment, the hook locking components 4 provide a hook sealing function, and the supporting components 5 provide a function of preventing the movable fan 2 from rotating inward along the axis of the hooking part due to the action of wind pressure; it should be noted that for the length of the blocked portion 52, it should be considered that the longer it is (the larger the contact area with the blocking portion 51), the better its sealing and supporting properties, but it should not exceed the range of the blocking portion 51.

[0078] In order to improve the sealing effect, the number of hook-and-lock components 4 and support components 5 can be increased, that is, in some embodiments, at least two groups of hook-and-lock components 4 are provided, and at least one group of support components 5 is provided, so as to form a multi-level hooking and multi-level supporting effect through multiple groups of hook-and-lock components 4 and support components 5, thereby improving the sealing performance.

[0079] like Fig.10 As shown, in some embodiments, the blocking portion 51 includes a blocking surface 511, and the blocked portion 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 opened, the blocking surface 511 is separated from the blocked surface 521. The blocking surface 511 and the blocked surface 521 can be in contact or separated according to the window opening state, and the force arm is transmitted to improve the sealing effect.

[0080] Due to the long force arm between the locking part and the sealing strip at the hook-and-lock position on the indoor side, the hook point will form a fulcrum for force when subjected to wind pressure, resulting in a rotation tendency at the lower frame of the movable fan 2, which reduces the sealing effect. Therefore, in some embodiments, the support assembly 5 can be set at a position on the indoor side of the hook-and-lock assembly 4, that is, the support assembly 5 is located on the opening direction side of the hook-and-lock assembly 4; the hook-and-lock assembly 4 is set at a position close to the outdoor side to improve the sealing effect. That is, the closer the hook position is to the outside, the smaller the force 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-and-lock structure, and the locking structure on the indoor side also acts as a supporting point.

[0081] In some embodiments, Fig.11 As shown, the blocking portion 51 includes a first blocking portion 551 and a second blocking portion 552; the blocked portion 52 includes a first blocked portion 561 and a second blocked portion 562; the first blocking portion 551 and the first blocked portion 561 form a blocking state; the second blocking portion 552 and the second blocked portion 562 form a blocking state. By means of the first blocking portion 551, the second blocking portion 552, the first blocked portion 561 and the second blocked portion 562, at least two supporting points can be formed, thereby increasing the supporting effect and improving 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 portion 551 blocks part or all of the first blocked portion 561 , and part or all of the second blocking portion 552 blocks part or all of the second blocked portion 562 .

[0083] In some embodiments, the blocking surface 511 and the hooking portion 42 are integrally formed, and the blocked surface 521 and the hooking member 41 are integrally formed, so as to improve stability, reduce the number of installed components, and improve the sealing effect.

[0084] In some embodiments, see Figure 6 The support component 5 can also be integrally arranged with the hook and lock component 4. For example, when the hook and lock component 4 includes a first hook member 411 and a first hook portion 421, the support component 5 can also be formed at the root of the first hook member 411 or other positions. At this time, the blocking portion 51 and the blocked portion 52 form a blocking state, which also provides a supporting effect.

[0085] In some embodiments, see Fig.12 The blocking portion 51 and the blocked portion 52 can also be designed to be in a non-direct contact state, that is, when the first hooking member 411 and the first hooking portion 421 are hooked, there is a gap between the blocking portion 51 and the blocked portion 52, and when the movable fan 2 and the fixed fan 3 have a relative movement, the blocking portion 51 contacts the blocked portion 52 again and forms a blocking state, thereby providing a supporting effect.

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

[0087] The movable leaf 2 and the fixed leaf 3 of the lifting window can be made of aluminum alloy, plastic steel, stainless steel and other materials. When the profiles made of these materials are in contact with each other, on the one hand, the friction coefficient is large, which is not conducive to hooking. On the other hand, under the long-term opening and closing action, it will cause the profile to wear and lock the service life of the profile. Therefore, in order to facilitate the hooking and extend the service life of the profile, in some embodiments, the hook locking assembly 4 also includes a self-lubricating part 43.

[0088] like Fig.13As shown, the self-lubricating member 43 can be arranged in the hook part 42 or on the hook part 41, and the sliding friction coefficient between the self-lubricating member 43 and the hook part 41 or the hook part 42 is less than the sliding friction coefficient between the hook part 41 and the hook part 42. For example, the self-lubricating member 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 composites. Polytetrafluoroethylene is a material with a low friction coefficient 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 a composite that can play a lubricating role between metal matrices.

[0089] The self-lubricating member 43 can replace the inner wall of the hooking part 42 to contact the hooking member 41, or replace the hooking member 41 to contact the inner wall of the hooking part 42 when the hooking member 41 enters the hooking part 42, so that the hooking member 41 will not directly contact the hooking part 42, thereby reducing the friction in the process of entering the hooking part 42. In addition, the self-lubricating member 43 can be detachably connected to the hooking part 42, that is, after the self-lubricating member 43 is worn to a certain extent, the self-lubricating member 43 can be replaced to reduce the direct wear between the profiles of the movable sash 2 and the fixed sash 3, thereby extending the service life of the window profile.

[0090] Therefore, if Fig.14 As shown, in some embodiments, the bottom of the hook portion 42 is provided with a receiving groove 424, and the self-lubricating member 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 arranged in the receiving groove 424. Among them, the receiving groove 424 can be a rectangular groove structure arranged in the hook portion 42, and the connecting portion 431 can be a rectangular plate structure adapted to the receiving groove 424, that is, the connecting portion 431 can be inserted into the receiving groove 424. One side of the connecting portion 431 is in contact with one side of the receiving groove 424, and the other side of the connecting portion 431 is connected to the lubricating portion 432.

[0091] Through the plug-in relationship between the receiving groove 424 and the connecting portion 431, the self-lubricating member 43 can be detachably connected to the hooking portion 42, so that the self-lubricating member 43 can be replaced after the self-lubricating member 43 is worn out after being used for a long time. In addition, the self-lubricating member 43 can also be a structural member in which the connecting portion 431 and the lubricating portion 432 are integrally formed, that is, the connecting portion 431 and the lubricating portion 432 are both made of materials with a small sliding friction coefficient, so as to reduce the process difficulty while meeting the lubrication performance requirements.

[0092] In some embodiments, the hooking member 41 and the hooking portion 42 are strip-shaped structural members that are continuously distributed along the extension direction of the profile, or the hooking member 41 and the hooking portion 42 are segmented structural members that are spaced apart along the extension direction of the profile. Figure 1 As shown, the profile extension direction is the extension direction of the profile on the side of the movable leaf 2 close to the fixed leaf 3 when the lifting window is in the closed state. That is, the hook locking component 4 can be set along the entire side or in sections.

[0093] Similarly, the self-lubricating member 43 is a strip-shaped structural member covering the hook member 41 or the hook portion 42, or the self-lubricating member 43 is a segmented structural member arranged at intervals in the hook portion 42. That is, the self-lubricating member 43 can be arranged along the entire edge or in segments, and the specific arrangement method can be set according to the application environment of the lifting window and the specific profile structure of the lifting window.

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

[0095] For example, when the hook member 41 and the hook portion 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 portion 42, and the number of segments, the segment spacing distance, the length of each segment, etc. of the hook member 41 and the hook portion 42 are consistent with the number of segments, the segment spacing distance, the length of each segment, etc. of the self-lubricating member 43, that is, the number of segments is the same, the segment spacing distance is equal, and the length of each segment of the hook member 41 and the hook portion 42 is greater than or equal to the length of each segment of the self-lubricating member 43.

[0096] By using segmented structural parts, the amount of window profiles used can be reduced, and the difficulty of profile mold opening can be reduced. At the same time, segmented structural parts can also be more targeted to adapt to the actual environment by setting segmented positions and setting hook seals 4 in areas prone to air leakage. It should be noted that when the hook member 41 and the hook portion 42 are segmented structural parts arranged at intervals along the extension direction of the profile, the hook member 41 and the hook portion 42 can both be segmented structures, or the hook member 41 can be a segmented structure, while the hook portion 42 can be a strip structure.

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

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

[0099] Based on the lifting window provided in the above-mentioned embodiments, a hooking and locking assembly is further provided in some embodiments of the present application, which is applied to the lifting window described in the above-mentioned embodiments. The lifting window includes: a frame 1, a movable fan 2 and a fixed fan 3; the movable fan 2 is movably connected to the frame 1; the fixed fan 3 is fixedly connected to the frame 1, and the hooking and locking assembly 4 includes a hook member 41 and a hook portion 42, and the hook member 41 and the hook portion 42 can be selectively hooked; one of the hook member 41 and the hook portion 42 is arranged on the movable fan 2, and the other of the hook member 41 and the hook portion 42 is arranged on the fixed fan 3.

[0100] It can be known from the above technical scheme that the above embodiment provides a lifting window and a hook locking assembly, wherein the hook locking assembly 4 is arranged between the movable sash 2 and the fixed sash 3 of the lifting window, and is used to seal the contact gap between the movable sash 2 and the fixed sash 3 when the lifting window is in a closed state. The hook locking assembly 4 includes a hook member 41 and a hook portion 42, and the hook member 41 and the hook portion 42 can be selectively hooked; one of the hook member 41 and the hook portion 42 is arranged on the movable sash 2, and the other of the hook member 41 and the hook portion 42 is arranged on the fixed sash 3. Through the hooking relationship between the hook member 41 and the hook portion 42 in the hook locking assembly 4, the movable sash and the middle sash can be locked or the movable sash and the fixed sash can be locked, forming a multi-stage locking effect. The support assembly 5 includes a blocking portion 51 and a blocked portion 52. When the hook locking assembly 4 is selectively hooked, the movable fan 2 will slightly rotate around the hooking portion as the axis under the action of the wind pressure when it is subjected to external wind pressure. The farther away from the hooking portion, the more serious the rotation between the movable fan 2 and the hook locking assembly 4, resulting in poor sealing performance between the hook locking assembly 4 and the frame of the movable fan 2, and reduced performance of the entire window. When the movable fan 2 is closed and the hook locking assembly 4 is selectively hooked, the blocking portion 51 cooperates with the blocked portion 52 to prevent the movable fan 2 from rotating around the hooking portion as the center when subjected to wind pressure. In addition, by providing the hook member 41 and the hook portion 42, the movable fan 2 and the fixed fan 3 can maintain a sealed state through hard materials, reduce the impact of external forces, and alleviate the problem of poor sealing performance of the lifting window.
