Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a mullion connection structure, an inward tilting sliding window, and a mullion connector. Background Technology
[0002] With the continuous development of building technology, inward-tilting sliding windows have become widely used due to their unique multi-functional opening mechanism. This type of product uses a sliding structure, offering excellent ventilation and sealing performance, and is suitable for various architectural scenarios. In practical applications, when the size of an inward-tilting sliding window exceeds a certain limit, a mullion is needed as the core load-bearing structure to withstand wind pressure loads, opening and closing stresses, and the weight of the profile. The connection strength of the mullion directly affects the overall stability and safety of the window frame. When designing narrow-sash profile structures, the extremely narrow cavity of the cross-shaped mullion places higher demands on the connection method.
[0003] However, traditional corner bracket connectors have many shortcomings in narrow cavity structures. For example, under extreme wind pressure conditions, they are prone to displacement of the mullions, which can lead to the failure of the entire window profile rod connection, tearing of the sealing strip and air leakage, while also increasing the risk of water leakage, seriously affecting the service life and performance of the window. Utility Model Content
[0004] The purpose of this utility model is to provide a mullion connection structure, an inward tilting sliding window, and a mullion connector. Through reasonable design, it not only simplifies the installation process and improves installation efficiency, but also significantly improves the stability and reliability of the connection.
[0005] In a first aspect, this utility model provides a mid-tie connection structure, comprising:
[0006] It is upright and has a first movable slot extending along the height direction;
[0007] A first connecting plate is movably disposed in the first movable slot. The first connecting plate is also provided with a first fixing hole, which is used for fixing screws to pass through and fix to the vertical rod.
[0008] It is horizontal and has a mounting cavity that extends in the horizontal direction;
[0009] The second connecting plate includes an integrally formed fixing part and an insertion part. The fixing part is fixedly disposed on the side of the first connecting plate opposite to the first movable slot. The insertion part extends horizontally out of the first movable slot so that the insertion part can be inserted into the mounting cavity. The insertion part is provided with a second fixing hole for a fixing screw to pass through and fix it to the cross brace.
[0010] The mullion connection structure provided by this utility model not only provides a track for the movement of the first connecting plate through the first movable slot, but also limits the horizontal movement of the first connecting plate. This design allows the first connecting plate to adjust its position within a certain range during installation, ensuring precise alignment with the mullion. Finally, fixing is achieved by inserting a fixing screw through the first fixing hole. This combination of limiting and fixing effectively prevents horizontal displacement of the first connecting plate, significantly improving the stability and reliability of the connection structure. In addition, the insertion part achieves a tight fit with the mullion by inserting into the mounting cavity of the mullion. This insertion design not only improves the stability of the connection, but also ensures a tight fit at the connection points, reducing loosening caused by vibration or external forces. Finally, fixing is achieved by inserting a fixing screw through the second fixing hole, further enhancing the reliability of the connection. This dual fixing method (insertion fit and screw fixing) ensures that the connection between the mullion and the vertical mullion remains stable under various usage conditions, effectively preventing connection failure caused by external forces.
[0011] Furthermore, there are two first fixing holes, which are distributed on opposite sides of the second connecting plate.
[0012] By employing the above technical solution and increasing the number of first fixing holes, multi-point fixing of the first connecting plate can be achieved. This multi-point fixing method can distribute the force more evenly, significantly improving the stability and bending strength of the connection structure. Under extreme wind pressure or large loads, this design can effectively prevent displacement and loosening of the first connecting plate, ensuring the firmness of the connection.
[0013] Furthermore, it also includes a third connecting plate, which is disposed at the end of the fixing part away from the insertion part. The vertical rod is also provided with a second movable slot extending in the height direction, and the opening direction of the second movable slot is perpendicular to the opening direction of the first movable slot. The third connecting plate is movably disposed in the second movable slot.
[0014] By adopting the above technical solution, the introduction of the third connecting plate further enhances the stability of the connection structure. A double-limiting system is formed by setting a second movable slot on the vertical mullion and movably placing the third connecting plate within this slot. This design not only improves the bending strength of the connection structure but also effectively prevents displacement of the vertical and horizontal mullions in multiple directions, ensuring the stability and reliability of the connection.
[0015] Furthermore, the third connecting plate is provided with a third fixing hole, which is used for fixing screws to pass through and fix to the vertical rod.
[0016] By adopting the above solution, a third fixing hole is provided on the third connecting plate, and it is fixed to the crossbeam with fixing screws, which further enhances the stability of the connection structure. This multi-point fixing method can distribute the force more evenly, significantly improve the bending strength and shear strength of the connection, and ensure the firmness of the connection under various usage conditions.
[0017] Furthermore, the third connecting plate is provided with a first fixing block and a second fixing block on opposite sides, and the second movable slot is provided with a first fixing slot and a second fixing slot on opposite sides. The first fixing block and the second fixing block can be engaged in the first fixing slot and the second fixing slot to restrict the third connecting plate from disengaging from the second movable slot in the horizontal direction.
[0018] By adopting the above technical solution, by setting a first fixing block and a second fixing block on opposite sides of the third connecting plate, and setting a first fixing slot and a second fixing slot on opposite sides of the second moving slot, this block and slot cooperation design can effectively restrict the movement of the third connecting plate in the horizontal direction.
[0019] Furthermore, the first connecting plate is provided with a third fixing block on the side facing the transverse beam, and the first movable slot is also provided with a third fixing slot. The third fixing block can be engaged in the third fixing slot to restrict the first connecting plate from disengaging from the first movable slot in the horizontal direction.
[0020] By employing the above technical solution, a third fixing block is provided on the side of the first connecting plate facing the crossbar, and a third fixing slot is provided on the first movable slot. This block and slot cooperation design effectively restricts the horizontal movement of the first connecting plate. This limiting design significantly improves the stability and reliability of the connection structure.
[0021] Furthermore, the end of the insertion part away from the fixing part is provided with a guide slope, which is used to guide the insertion part into the mounting cavity.
[0022] By adopting the above technical solution, the guide bevel design of the insertion part significantly simplifies the installation process. During installation, the guide bevel helps the insertion part to be inserted more smoothly into the mounting cavity of the mullion, reducing alignment difficulties and adjustment time during the installation process.
[0023] Furthermore, there are two horizontal mullions, which are located on opposite sides of the vertical mullion.
[0024] Secondly, the present invention provides an inward tilting sliding window, which includes any of the above-mentioned mullion connection structures.
[0025] Thirdly, this utility model provides a mullion connector for connecting vertical mullions and horizontal mullions, comprising:
[0026] A first connecting plate is used to slide with a first movable slot of the vertical rod. The first connecting plate is provided with a first fixing hole, which is used for fixing screws to pass through and fix to the vertical rod.
[0027] The second connecting plate includes an integrally formed fixing part and an insertion part. The fixing part is fixedly disposed on the first connecting plate. The insertion part can extend horizontally out of the first moving slot after the first connecting plate is connected to the first moving slot, so that the insertion part can be inserted into the mounting cavity of the crossbeam. The insertion part is provided with a second fixing hole for a fixing screw to pass through and fix it to the crossbeam.
[0028] As can be seen from the above, the mullion connection structure provided by this utility model not only provides a track for the movement of the first connecting plate through the first movable slot, but also limits the horizontal movement of the first connecting plate. This design allows the first connecting plate to adjust its position within a certain range during installation, ensuring its precise alignment with the mullion. Finally, fixing is achieved by inserting a fixing screw through the first fixing hole. This combination of limiting and fixing effectively prevents the first connecting plate from shifting in the horizontal direction, significantly improving the stability and reliability of the connection structure. In addition, the insertion part achieves a tight fit with the mullion by inserting into the mounting cavity of the mullion. This insertion design not only improves the stability of the connection, but also ensures a tight fit of the connection parts, reducing loosening caused by vibration or external forces. Finally, fixing is achieved by inserting a fixing screw through the second fixing hole, further enhancing the reliability of the connection. This dual fixing method (insertion fit and screw fixing) ensures that the connection between the mullion and the vertical mullion remains stable under various usage conditions, effectively preventing connection failure caused by external forces.

Finally, it is fixed by inserting a fixing screw through the first fixing hole 210.

[0056] Reference Appendix Figure 2 Appendix Figure 6 The installation process of the mullion connection structure is as follows:
[0057] First, align the first connecting plate 200 and the third connecting plate 500 with the first movable slot 110 and the second movable slot 120 respectively, insert them, and move them to the corresponding height. Use fixing screws to pass through the first fixing hole 210 and the third fixing hole 510 to fix the first connecting plate 200 and the third connecting plate 500 on the vertical stand 100. Then move the horizontal stand 300 so that the insertion part 420 is inserted into the mounting cavity 310. Then fix the insertion part 420 and the horizontal stand 300 by using fixing screws to pass through the second fixing hole 430, thereby realizing the installation and fixation of a single horizontal stand 300 and the vertical stand 100.
[0058] This utility model also provides an inward tilting sliding window, including any of the above-mentioned mullion connection structures.
[0059] Reference Appendix Figure 2 This utility model also provides a mid-mount connector for connecting a vertical mullion 100 and a horizontal mullion 300, including a first connecting plate 200 and a second connecting plate 400. The first connecting plate 200 is slidably connected to a first movable slot 110 of the vertical mullion 100.

The insertion part 420 is provided with a second fixing hole 430 for a fixing screw to pass through and fix it to the horizontal mullion 300.
[0060] It is worth noting that both the first connecting plate 200 and the second connecting plate 400 are manufactured using a precision-cast 304 stainless steel integrated molding process. This choice of material and process not only endows the connecting plates with high strength and excellent corrosion resistance, but also effectively solves the problem of insufficient strength in narrow cavity structures through the adaptability of the precision casting process.
[0061] Specifically, both the first connecting plate 200 and the second connecting plate 400 are 8mm thick. This design minimizes the space occupied by the structure, perfectly fitting the extremely narrow cavity of the inward-tilting side-sliding window's cross mullion. Simultaneously, this design cleverly solves the common problem of gaps at the splicing surface during cross mullion assembly, significantly improving the strength and stability of the connection points. In terms of appearance, the overall shape is flat and aesthetically pleasing, with no exposed screws, harmonizing with the appearance of the movable sash and greatly enhancing the overall aesthetics of the window.
