Detailed Description of the Embodiment

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0032] In the description of the embodiments of this application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In this application, unless otherwise clearly defined and limited, terms such as "install", "connect", "link", "fix", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0035] A lift window is a new type of window that can achieve the opening of the window sash in the height direction. It can be opened or closed in the window frame without opening outward or inward, so it does not occupy internal space, is not easily damaged by collision, and its appearance is more concise and beautiful. Therefore, lift windows are increasingly widely used in the field of building construction.

[0036] In the related art, a lifting window includes a mullion structure connected to a fixed frame, a sash, a vertical frame, and a slide rail. Among them, a slide rail is installed on the vertical frame, and the slide rail further includes a vertical slide rail and a deflecting slide rail. The sash is provided with a guiding component that cooperates with the vertical frame. The sash can slide up and down along the vertical slide rail and switch positions between the vertical slide rail and the deflecting slide rail through the guiding component, so as to selectively cooperate and connect with the mullion structure for room ventilation by opening the window.

[0037] However, at present, the locking effect between the sash and the mullion structure in the lifting window is poor.

[0038] To solve the above problems, an embodiment of the present application provides a mullion structure applied to a lifting window.

[0039] The applicant of the present application will describe the solution of the embodiment of the present application in detail with reference to the accompanying drawings of the specification.

[0040] Figure 1 is a schematic diagram of the connection between the mullion structure of an embodiment of the present application and the fixed frame 1000 and the sash 900; Figure 2 is a schematic structural diagram of the mullion structure of an embodiment of the present application.

[0041] Reference Figure 1 and Figure 2 As shown, in a first aspect, an embodiment of the present application provides a mullion structure, which includes a support portion 100 and a mating portion 300.

[0042] Among them, the fixing portion 200 is used to be arranged on the fixed frame 1000 of the lifting window, and the fixing portion 200 has a first end in the width direction of the fixing portion 200. It should be noted that the width direction of the fixing portion 200 is as shown in Figure 2 . Exemplarily, the fixing portion 200 can be fixed to the side frame of the fixed frame 1000 by bolts, riveting, and other fixing methods.

[0043] Among them, the mating portion 300 includes a connection end 310, a limiting portion 320, and a mating end 330. The connection end 310 is connected to the limiting portion 320, and the mating end 330 is arranged on the side of the limiting portion 320 facing away from the fixing portion 200. Exemplarily, the connection end 310 and the mating end 330 are respectively arranged on both sides of the limiting portion 320 in the thickness direction, and the limiting portion 320 can be a limiting block. It should be noted that the thickness direction of the limiting portion 320 is as shown in Figure 2 .

[0044] In addition, the fixing portion 200 has a second end opposite to the position of the first end. The connection end 310 is connected to the second end, and the mating end 330 is used to selectively cooperate and connect with the sash 900, so that the sash can be locked together with the mullion structure, ensuring a good locking effect between the two.

[0045] Exemplarily, the connection end 310 can be connected to the second end by fixed connection means such as welding or bolting, or can be integrally formed, or can be arranged in cooperation.

[0046] Figure 3 It is a schematic diagram after the middle stile structure in another embodiment of the present application is connected to the fixed frame 1000 and the opening sash 900. Refer to Figure 3 As shown, the connection end 310 of the cooperation part 300 is installed in cooperation with the fixed block through the fixed slot.

[0047] In some examples, the cooperation end 330 includes a second limiting member 332. One end of the second limiting member 332 is connected to the limiting part 320. The second limiting member 332 and the limiting part 320 jointly enclose a first limiting space 600, and a part of the opening sash 900 is selectively fitted in the first limiting space 600. It can be understood that when the second limiting member 332 is inclined relative to the side surface of the limiting part 320, the second limiting member 332 can enclose a first limiting space 600 with one side open with the limiting part 320.

[0048] In some other examples, continue to refer to Figure 2 As shown, the cooperation end 330 includes a first limiting member 331 and a second limiting member 332. One end of the first limiting member 331 is connected to the limiting part 320, the other end of the first limiting member 331 is connected to the second limiting member 332, and the first limiting member 331, the second limiting member 332 and the limiting part 320 jointly enclose a first limiting space 600, and a part of the opening sash 900 is selectively fitted in the first limiting space 600.

[0049] Exemplarily, the first limiting member 331, the second limiting member 332 and the limiting part 320 can be integrally formed to ensure higher overall strength. In addition, the first limiting member 331 extends parallel to the width direction of the limiting part 320, the second limiting member 332 extends along the thickness direction perpendicular to the limiting part 320 and is connected to the first limiting member 331. The first limiting member 331, the second limiting member 332 and the limiting part 320 jointly enclose a U-shaped first limiting space 600, and the hook lock of the opening sash 900 can be fitted in the first limiting space 600, so as to lock the opening sash 900 and fix it to the fixed frame 1000.

[0050] Continue to refer to Figure 2 As shown, in some other embodiments, the middle stile structure further includes a support part 100.

[0051] The support part 100 is connected to the first end and extends along the width direction perpendicular to the fixing part 200 to facilitate the arrangement of a sealing member for sealing the opening sash 900 on the support part 100.

[0052] Exemplarily, the support part 100 can be welded to the first end of the fixing part 200 or integrally formed with the fixing part 200. It should be noted that the support part 100 extending in the width direction perpendicular to the fixing part 200 does not mean that the support part 100 is perpendicular to the fixing part 200. There may be a certain angle of inclination, as long as it is ensured that the support part 100 is generally perpendicular to the fixing part 200.

[0053] In addition, a first seal 400 is provided at one end of the support part 100 away from the fixing part 200, and the first seal 400 faces the side of the fixing part 200. The support part 100 is cooperatively connected with the opening sash 900 of the lifting window through the first seal 400.

[0054] In some examples, a first mounting part 110 is provided on the side of the support part 100 facing the fixing part 200. The first seal 400 is provided in the first mounting part 110, and the first seal 400 protrudes from the surface of the support part 100. It can be understood that when the opening sash 900 of the lifting window is closed, the opening sash 900 will tightly press against the first seal 400, and the first seal 400 will elastically deform, thereby sealing between the support part 100 and the opening sash 900. Exemplarily, the first mounting part 110 is configured as a first mounting groove.

[0055] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, a second mounting part 210 is provided on the side of the fixing part 200 facing the support part 100. A second seal 500 is provided in the second mounting part 210, and the fixing part 200 is selectively cooperatively connected with the opening sash 900 of the lifting window through the second seal 500.

[0056] As Figure 1 shown, the second mounting part 210 is provided at the middle position of the fixing part 200. The second seal 500 is provided on the second mounting part 210, and the second seal 500 protrudes from the surface of the second mounting part 210. After the opening sash 900 is connected to the fixed frame 1000, the lower part of the opening sash 900 is in close contact with the second seal 500, and the second seal 500 is deformed by the extrusion of the opening sash 900, thereby obtaining a better sealing effect. Exemplarily, the second mounting part 210 is configured as a second mounting groove.

[0057] It can be understood that the double-sealing design of the first seal 400 and the second seal 500 can make the connection between the opening sash 900 and the mullion structure have a better sealing effect to avoid air leakage or rain leakage at the connection.

[0058] Continue to refer to Figure 2As shown, in some embodiments, a protrusion 321 is provided on one side of the limiting portion 320 facing the first limiting space 600. The protrusion 321 extends along the thickness direction of the limiting portion 320. The protrusion 321 can increase the strength of the limiting portion 320 and play a decorative role, making the lifting window more beautiful.

[0059] Continue to refer to Figure 2 As shown, the mullion structure further includes a third limiting member 1100. Among them, the third limiting member 1100 is disposed on the side opposite to the limiting portion 320 of the fixing portion 200, and the extending direction of the third limiting member 1100 is opposite to the extending direction of the supporting portion 100. The third limiting member 1100, the fixing portion 200, and the limiting portion 320 jointly enclose a second limiting space 700, and the fixed frame 1000 can be disposed in the second limiting space 700.

[0060] Exemplarily, the distance between the third limiting member 1100 and the limiting portion 320, that is, the width of the second limiting space 700, is greater than or equal to the thickness of the frame of the fixed frame 1000, so that the fixed frame 1000 can be fixed in the second limiting space 700. At the same time, since the second limiting space 700 is U-shaped, it can cover the edge position of the fixed frame 1000, which can improve the sealing at the connection between the fixed frame 1000 and the fixing portion 200 of the mullion structure, and further improve the performance of the entire window. It can be understood that the fixed frame 1000 can be fixed in the second limiting space 700 by bolts or other connecting members, or the outer frame of the mullion structure and the fixed frame 1000 can be arranged together by an integral molding method. The fixed frame 1000 is located in the second limiting space 700, and the connection method is not specifically limited.

[0061] In some examples, such as Figure 3 As shown, through holes 220 communicating with both sides in the thickness direction of the fixing portion 200 are provided on the fixing portion 200 of the mullion structure, that is, through holes 220 penetrating the fixing portion 200 up and down, and the through holes 220 are located between the supporting portion 100 and the second mounting portion 210. It can be understood that by connecting both sides of the fixing portion 200 through the through holes 220, rainwater can be prevented from accumulating in the space enclosed by the supporting portion 100 and the fixing portion 200, so as to prevent rainwater from flowing into the window. Exemplarily, the number of the through holes 220 can be multiple, which is more conducive to the flow of rainwater.

[0062] Exemplarily, the through holes 220 include a first through hole 221 and a second through hole 222. The first through hole 221 and the second through hole 222 are respectively located on both sides of the fixing part 200 in the thickness direction, and the first through hole 221 and the second through hole 222 are arranged offset in the thickness direction of the fixing part 200. That is to say, the centers of the first through hole 221 and the second through hole 222 are staggered, so as to prevent the two sides of the fixing part 200 in the thickness direction from being directly penetrated, thereby increasing the pressure when the external wind enters the space above the fixing part 200 through the first through hole 221 and the second through hole 222, which is beneficial to the water in the space above the fixing part 200 to flow down through the first through hole 221 and the second through hole 222.

[0063] In addition, a channel 800 is provided between the support part 100 and the third limiting part 1100, and the channel 800 is communicated with the through holes 220. Exemplarily, the channel 800 can be inclined to facilitate the flow of rainwater flowing from the through holes 220 to the channel 800, ensuring that the water can be drained away in time. In addition, since the through holes 220 are arranged inside the channel 800, the influence of the wind pressure on the drainage of the through holes 220 can be reduced, thereby improving the drainage efficiency.

[0064] In some other embodiments, the mullion structure is an integrally formed part to improve the overall strength of the mullion structure, reduce the wall thickness and cross-sectional area of the profile, and also reduce the cost. In addition, since the width of the profile of the mullion structure becomes narrower, it not only improves the aesthetics of the window, but also reduces the ratio of the area of the whole window frame to the area of the glass, and improves the heat insulation performance of the whole window.

[0065] Figure 4 It is a schematic structural diagram of the lifting window in the present application.

[0066] Reference Figure 4 As shown, in the second aspect, the present application further provides a lifting window, including a fixed frame 1000, an opening sash 900 and the mullion structure in the first aspect. The mullion structure is fixed on the fixed frame 1000, and the opening sash 900 is selectively connected to the mullion structure to realize the selective connection of the opening sash 900 to the fixed frame 1000.

[0067] This lifting window has all the beneficial effects of the mullion structure in the first aspect above, and will not be elaborated here.

[0068] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application on the basis of several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0069] In the above specific embodiments, the objectives, technical solutions, and beneficial effects of the embodiments of the present application have been further described in detail. It should be understood that the above are only the specific embodiments of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
