[0001] This utility model relates to the field of door and window technology, and in particular to a sliding door and window anti-collision closing structure, closing cover plate, and decorative cover plate. Background Technology

[0002] Panoramic sliding windows, as a modern aluminum profile window and door product that integrates a wide field of view, high sealing performance and strong wind pressure resistance, have become an indispensable aluminum profile window and door product in modern buildings due to their open view, simple narrow frame aesthetic design and high integration with the architectural appearance.

[0003] Referring to a sliding door and window trim adjustment structure with publication number CN217712344U, conventional trim structures typically require screws for fixing during installation. This installation method is not only complex, requiring specialized tools and skills, but also prone to damaging the window frame and sash during the process. Furthermore, disassembling the screws after installation is very difficult, and replacement or repair often necessitates damaging the original structure. In addition, due to the difficulty of installation and disassembly, existing trim solutions are very inconvenient for maintenance and replacement. Once the trim material is damaged or its sealing performance deteriorates, the replacement process is cumbersome and costly. Utility Model Content

[0004] The purpose of this utility model is to provide a sliding door and window anti-collision closing structure, closing cover plate and decorative cover plate, thereby simplifying the installation and maintenance process of the closing structure by optimizing the connection method of the closing structure.

[0005] In a first aspect, this utility model provides a sliding door / window interlocking structure, comprising:

[0006] A glass fan is provided with a groove for closing the opening, and a first limiting block and a second limiting block are respectively provided on the opposite sides of the opening of the groove;

[0007] The abutting cover plate includes a first surface and a second surface disposed opposite to each other. The first surface is used to abut against the receiving opening. The second surface is provided with a first locking block and a second locking block. The abutting cover plate can undergo elastic deformation so that the first locking block can be locked into the side of the first limiting block facing the receiving opening groove, and the second locking block can be locked into the side of the second limiting block facing the receiving opening groove.

[0008] The sliding door and window interlocking structure provided by this utility model achieves quick installation and disassembly without screws by designing an elastically deformable abutment cover and utilizing the interlocking structure of the first and second locking blocks with the first and second limiting blocks. This design avoids the complex operation requiring professional tools and skills in traditional screw installation methods, and also reduces potential damage to the window frame and sash.

[0009] Furthermore, the glass fan includes a first glass fan and a second glass fan, and the abutting cover includes a closing cover and a decorative cover. Both the first glass fan and the second glass fan are provided with closing grooves. The closing cover is disposed in the closing groove of the first glass fan, and the decorative cover is disposed in the closing groove of the second glass fan. The first glass fan can move toward the second glass fan so that the closing cover and the decorative cover abut against each other to receive the opening.

[0010] The above technical solution, using the combined use of the sealing cover and the decorative cover, provides a double-layer sealing effect for sliding doors and windows. When the first and second glass panes collide, the two cover plates abut against each other, further enhancing the sealing performance and effectively preventing the penetration of air and rainwater.

[0011] Furthermore, the closing cover plate has a first shielding edge and a second shielding edge on the side facing the interior. The first shielding edge is located on the side of the closing cover plate facing the first glass sash, and the second shielding edge is located on the side of the closing cover plate facing the second glass sash. When the first glass sash and the second glass sash abut against each other, the first shielding edge and the second shielding edge can shield the gap between the first glass sash and the second glass sash.

[0012] Using the above technical solution, the side of the end cap facing the interior is provided with a first and a second shielding edge. These two shielding edges can effectively cover the gap between the first and second glass panes. This design not only enhances the overall aesthetics of the doors and windows, but also makes them appear cleaner and more seamless when closed, blending with the minimalist aesthetics of modern architecture.

[0013] Furthermore, it also includes a sealing strip, wherein a strip groove is provided on the side of the second shielding edge facing the second glass sash, and the sealing strip is detachably disposed in the strip groove, and the sealing strip is used to seal the gap between the second shielding edge and the second glass sash.

[0014] Using the above technical solution, the sealing strip is installed in the strip groove on the side of the second shield facing the second glass pane, which can effectively prevent the intrusion of external dust and moisture, thereby improving the sealing performance of the window. In addition, the sealing strip is installed in the strip groove and will not be exposed, maintaining the overall simplicity and aesthetics of the door and window.

[0015] Furthermore, it also includes an elastic glue rod, and the side of the first shielding edge facing the first glass sash is provided with a glue rod groove. The elastic glue rod is detachably disposed in the glue rod groove. When the closing cover plate is disposed in the closing groove, the elastic glue rod can abut against the side of the first glass sash away from the closing groove.

[0016] Using the above technical solution, the elastic adhesive rod is installed in the adhesive rod groove on the side of the first shielding edge facing the first glass sash, allowing it to fit tightly against the side of the first glass sash away from the first sealing groove. This design not only further enhances the sealing performance between the sealing cover and the first glass sash but also provides additional structural support for the first shielding edge, making it less prone to deformation or loosening during long-term use. Furthermore, the elastic adhesive rod is installed within the adhesive rod groove and is not exposed, maintaining the overall clean and aesthetically pleasing appearance of the door and window.

[0017] Furthermore, the sum of the extension lengths of the first blocking edge and the second blocking edge is 16mm.

[0018] Furthermore, it also includes a sealing strip. The decorative cover plate has a groove for the sealing strip on the side facing the first glass sash. The sealing strip is detachably disposed in the groove and is used to abut against the closing cover plate to seal the gap between the decorative cover plate and the closing cover plate.

[0019] Using the above technical solution, the sealing strip is installed in the groove on the side of the decorative cover plate facing the first glass sash, allowing it to fit tightly against the end cover plate. This design further enhances the sealing performance between the decorative cover plate and the end cover plate, effectively preventing the penetration of air and moisture.

[0020] Furthermore, the number of sealing strips is at least two, and the at least two sealing strips are spaced apart between the first and second clips of the decorative cover plate.

[0021] Using the above technical solution, at least two sealing strips are used, and these sealing strips are spaced apart between the first and second locking blocks of the decorative cover. This multi-layer sealing design can further enhance the sealing performance between the decorative cover and the closing cover, effectively preventing the penetration of air and moisture.

[0022] Secondly, the present invention provides a sealing cover plate, comprising a first surface and a second surface disposed opposite to each other. The first surface is used to abut against the sealing opening, and the second surface is provided with a first locking block and a second locking block. The sealing cover plate is capable of elastic deformation, so that the first locking block can be engaged with the side of the first limiting block of the glass sash facing the sealing groove, and the second locking block can be engaged with the side of the second limiting block of the glass sash facing the sealing groove. The side of the sealing cover plate facing the interior is provided with a first shielding edge and a second shielding edge, which are used to shield the gap between the two glass sashes.

[0023] Using the above technical solution, the end cap can undergo elastic deformation, allowing the first and second locking blocks to engage with the first and second limiting blocks on the side facing the end groove, respectively. This design not only simplifies the installation process but also enhances the connection stability between the end cap and the glass panel. Furthermore, the end cap has a first and second shielding edge on the side facing the interior, which can conceal the gap between the two glass panels. This design not only improves aesthetics but also further enhances sealing performance.

[0024] Thirdly, the present invention provides a decorative cover plate, comprising a first surface and a second surface disposed opposite to each other. The first surface is used to abut against the receiving opening, and the second surface is provided with a first locking block and a second locking block. The decorative cover plate is capable of elastic deformation, such that the first locking block can be engaged with the side of the first limiting block of the glass sash facing the receiving opening groove, and the second locking block can be engaged with the side of the second limiting block of the glass sash facing the receiving opening groove. The decorative cover plate is also provided with a sealing strip groove, and a detachably disposed sealing strip is provided in the sealing strip groove. The sealing strip is used to abut against the receiving opening cover plate to seal the gap between the decorative cover plate and the receiving opening cover plate.

[0025] Using the above technical solution, the decorative cover plate can undergo elastic deformation, allowing the first and second locking blocks to respectively engage with the first and second limiting blocks on the side facing the closing groove. This design not only simplifies the installation process but also enhances the connection stability between the decorative cover plate and the glass sash. Furthermore, the decorative cover plate is equipped with a groove for installing a removable sealing strip. This design provides a stable installation position for the sealing strip, ensuring a tight fit with the closing cover plate and achieving a good sealing effect.

[0026] As can be seen from the above, the sliding door and window anti-collision closing structure provided by this utility model, through the design of an elastically deformable abutment cover plate and the interlocking structure of the first and second locking blocks with the first and second limiting blocks, achieves quick installation and disassembly without screws.
