Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a high-strength PVC plastic steel door and window cross mullion connector. Background Technology

[0002] PVC windows and doors are a product that the government is focusing on promoting. They offer significant improvements in heat insulation, sound insulation, anti-aging properties, and sealing performance compared to traditional steel, wooden, and aluminum alloy windows and doors.

[0003] In architectural decoration, the cross window is a common door and window structure. During installation, an outer frame needs to be installed at the window location on the wall, then cross mullions are installed inside the outer frame, and finally, multiple window panels are installed within the outer frame using the cross mullions. The cross mullion consists of horizontal mullions and vertical mullions positioned on either side of the horizontal mullions. The side walls of the horizontal mullions have glass mounting grooves for installing the windows and drainage channels for drainage. A sealing strip is installed between the drainage channels and the glass mounting grooves.

[0004] Traditional cross-shaped mullions are installed using L-shaped metal strips to connect the horizontal and vertical mullions. These strips are placed at the corners where the mullions are perpendicular to each other, and then multiple bolts are threaded through them to secure the mullions. However, the PVC mullions are prone to shrinkage in cold weather. When the mullions shrink, they can pull on the L-shaped metal strips, causing the bolts connecting the mullions to strip and be pulled out, resulting in gaps between the mullions (a phenomenon known as cold shrinkage and pull-out). This ultimately affects the insulation performance of the doors and windows. Utility Model Content

[0005] In view of the above problems, this utility model provides a high-strength PVC plastic steel door and window cross mullion connector.

Detailed Implementation

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This application discloses a high-strength PVC plastic steel door and window cross mullion connector, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a square tube 2 for insertion into the mullion 11, and two connecting blocks 3 for insertion into the inner sides of vertical mullions 12. One end of each connecting block 3 extends out of the vertical mullion 12 and is integrally fixed with a base 4. The two bases 4 are respectively set on the outer walls of the two sides of the mullion 11. The bases 4 are connected to the square tube 2 and the mullion 11 by a first bolt 5, and the connecting blocks 3 are connected to the corresponding vertical mullions 12 by a second bolt 6. Fasteners are also provided between the two connecting blocks 3.

[0023] In this embodiment, the cross mullion 11 and the vertical mullions 12 arranged on both sides of the cross mullion 11 are spliced ​​together to form a cross mullion 1. The base 4, the side wall of the square tube 2 and the side wall of the cross mullion 11 are all provided with first threaded holes adapted to the first bolt 5, and the side wall of the connecting block 3 and the side wall of the vertical mullion 12 are all provided with second threaded holes adapted to the second bolt 6.

[0024] The square tube 2 is inserted into the cross stile 11 and moved to the position where the cross stile 11 connects to the vertical stile 12. Then, the first bolt 5 is threaded onto the base 4, the side wall of the square tube 2, and the side wall of the cross stile 11, thus fixing the connecting block 3, the cross stile 11, and the square tube 2. Next, the vertical stile 12 is inserted onto the outside of the connecting block 3, and the second bolt 6 is threaded onto the connecting block 3 and the vertical stile 12, thus fixing the connecting block 3 and the vertical stile 12. In addition, fasteners can also be used to fix the two connecting blocks 3. This application provides a high-strength PVC plastic steel door and window cross stile 1 connector, which improves the connection stability between the cross stile 11 and the vertical stile 12, and has the effect of improving the thermal insulation performance of doors and windows.

[0025] Furthermore, the base 4 is adapted to the width of the glass placement groove 111 of the crossbar 11.

[0026] In this embodiment, the base 4 is in contact with the two inner sidewalls of the glass placement groove 111 on both sides, which can improve the installation stability of the connecting block 3 on the crossbar 11.

[0027] To further improve the installation stability of the connecting block 3 on the crossbeam 11, a positioning platform 7 adapted to the width of the drainage groove 112 of the crossbeam 11 is integrally fixed on the outer wall of the connecting block 3, and an avoidance opening 8 is formed between the positioning platform 7 and the base 4 to avoid the rubber strip on the crossbeam 11.

[0028] Specifically, the fasteners include fixing bolts 9, which pass through the two connecting blocks 3, the crossbar 11 and the square tube 2 and are threaded with locking nuts (not shown in the figure).

[0029] In this embodiment, through holes are provided on the two connecting blocks 3, the crossbar 11 and the square tube 2 for the fixing bolts 9 to pass through. After the fixing bolts 9 pass through these through holes, they are threadedly connected to the locking nuts. Then, the locking nuts are tightened to securely install the two connecting blocks 3 on both sides of the crossbar 11.

[0030] Reference Figure 4 and Figure 5 The square tube 2 is equipped with a positioning element 10 to limit its own movement relative to the connection position between the crossbeam 11 and the vertical stile 12. The positioning element 10 includes two positioning heads 101. A connecting tube 102 for the fixing bolt 9 to pass through is welded inside the square tube 2. The two positioning heads 101 are coaxially slidably disposed inside the connecting tube 102 and located at both ends of the connecting tube 102. Positioning holes 113 are respectively opened on both sides of the crossbeam 11 at the connection position for insertion and cooperation with the two positioning heads 101. An elastic element is provided inside the connecting tube 102 to drive the two positioning heads 101 to move and move away from each other.

[0031] In this embodiment, the position of the positioning hole 113 is the same as the position of the through hole on the crossbar 11. When the square tube 2 moves and the positioning head 101 passes through the positioning hole 113, the elastic element can drive the positioning head 101 to move and insert into the positioning hole 113, which improves the convenience of the workers when installing the square tube 2.

[0032] To facilitate the insertion of the positioning head 101 into the positioning hole 113, a chamfer 1011 is provided on the outer wall of the end of the positioning head 101 that is used to insert into the positioning hole 113.

[0033] Specifically, the elastic element includes a spring 103, which is coaxially disposed inside the connecting tube 102, and both ends of the spring 103 are connected to two positioning heads 101 respectively.

[0034] In this embodiment, the two ends of the spring 103 abut against the two positioning heads 101 respectively. The two positioning heads 101 can move away from each other under the elastic force of the spring 103 so that they can be inserted into the corresponding positioning holes 113.

[0035] The implementation principle of a high-strength PVC plastic steel door and window cross mullion connector according to an embodiment of this application is as follows: A square tube 2 is inserted into the horizontal mullion 11 and moved to the position where the horizontal mullion 11 connects to the vertical mullion 12. Then, a first bolt 5 is threaded onto the base 4, the side wall of the square tube 2, and the side wall of the horizontal mullion 11, thus fixing the connecting block 3, the horizontal mullion 11, and the square tube 2. Next, the vertical mullion 12 is inserted onto the outside of the connecting block 3, and a second bolt 6 is threaded onto the connecting block 3 and the vertical mullion 12, thus fixing the connecting block 3 and the vertical mullion 12. In addition, fasteners can also be used to fix the two connecting blocks 3. This improves the connection stability between the horizontal mullion 11 and the vertical mullion 12, and has the effect of improving the thermal insulation performance of doors and windows.
