Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, and in particular to a frame connection structure and its folding door and window. Background Technology
[0002] Currently, the horizontal and vertical profiles of the frame on the market are usually connected by screws at a 90° angle. A 90° connection means that the top of a vertical frame is connected to the side of the top of a horizontal frame, or the top of a horizontal frame is connected to the side of the top of a vertical frame. This connection method makes the load-bearing point of the folding door fall on the screw. However, the shear force that the screw can withstand is limited, making it difficult for the frame to support a large door leaf. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a frame connection structure.
[0004] This utility model is achieved through the following technical solution:

[0032] Please see Figures 1 to 4 This utility model proposes a frame connection structure 10, including: a horizontal frame 11, a vertical frame 12 and a first connector 13. The first connector 13 includes a first connecting end 131 and a second connecting end 132. The first connecting end 131 is connected to the horizontal frame 11, and the second connecting end 132 is inserted into the first insertion groove 121 of the vertical frame 12 so that the end face of the vertical frame 12 abuts against the horizontal frame 11, and the second connecting end 132 and the first insertion groove 121 are in clearance fit.
[0033] When assembling the frame connection structure 10, the horizontal frame 11 is first connected to the first connecting end 131 of the first connector 13. Then, the second connecting end 132 of the first connector 13 is inserted into the first insertion slot 121 on the vertical frame 12 to complete the assembly of the frame connection structure 10. Since the end face of the vertical frame 12 should abut against the horizontal frame 11, the force is changed from a point to a surface, avoiding local stress concentration and improving the load-bearing capacity of the frame connection structure 10. When the frame connection structure 10 is supporting a large door leaf, it is less prone to deformation or damage, improving the operational stability and safety of the folding door. Furthermore, the second connecting end 132 of the first connector 13 and the first insertion slot 121 are in clearance fit, allowing the second connecting end 132 to have a certain amount of movement space within the first insertion slot 121, thereby reducing friction and resistance during assembly and improving assembly efficiency.
[0034] The frame connection structure 10 proposed in this utility model has a vertical frame 12 end face that abuts against the horizontal frame 11, changing the force from a point to a surface, avoiding the phenomenon of local stress concentration, and improving the load-bearing capacity of the frame connection structure 10 for large-sized door panels.
[0035] Please see Figure 2 The horizontal frame 11 is provided with a first mounting groove 111, and the first connecting end 131 is connected to the first mounting groove 111.
[0036] Specifically, a first mounting groove 111 is provided on the horizontal frame 11, and the first connecting end 131 of the first connector 13 is connected to the first mounting groove 111, which increases the contact area between the first connector 13 and the horizontal frame 11, realizes the dispersion of the stress points, and improves the load-bearing capacity of the frame connection structure 10.
[0037] Please see Figure 2 Both sides of the first mounting groove 111 are provided with snap-fit parts 112. When the first connector 13 is connected to the horizontal frame 11, the first connecting end 131 snaps into the snap-fit part 112.
[0038] Specifically, when installing the first connector 13 into the first mounting slot 111, firstly, align the first connecting end 131 of the first connector 13 with the first mounting slot 111 on the horizontal frame 11, and apply force to push the first connector 13 into the first mounting slot 111 until the first connecting end 131 is fully engaged with the snap-fit part 112, thus completing the installation of the first connector 13 into the horizontal frame 11. The connection method of snapping the first connecting end 131 with the snap-fit part 112 ensures good connection stability between the first connector 13 and the horizontal frame 11. At the same time, it simplifies the installation steps of the frame connection structure 10 and improves the assembly efficiency of the frame connection structure 10.
[0039] Please refer to it again. Figure 2The frame connection structure 10 also includes a fastener 14, which is rotatably connected to the first connector 13. When the first connector 13 is connected to the horizontal frame 11, the fastener 14 secures the first connector 13 to the first mounting groove 111.
[0040] Specifically, a threaded hole is provided through the fastener 14. The fastener 14 is rotatably connected to the threaded hole, pushing the first connector 13 into the first mounting groove 111. After the first connecting end 131 of the first connector 13 engages with the snap-fit part 112, the fastener 14 is rotated to secure the first connector 13 in the first mounting groove 111, thereby preventing the first connector 13 from loosening and falling off, and improving the overall stability of the frame connection structure 10.
[0041] Please see Figure 3 The fastener 14 includes a screwing end 141 and an abutting end 142 disposed opposite to each other. Rotating the screwing end 141 causes the abutting end 142 to abut against the first mounting groove 111, so that the first connector 13 is fastened to the first mounting groove 111.
[0042] Specifically, by rotating the screwing end 141 of the fastener 14, the abutting end 142 of the fastener 14 abuts against the groove wall of the first mounting groove 111. When the abutting end 142 of the fastener 14 abuts against the groove wall of the first mounting groove 111, the first connector 13 is fastened in the first mounting groove 111, thereby improving the connection stability between the first connector 13 and the horizontal frame 11.
[0043] Please refer to it again. Figure 3 The frame connection structure 10 also includes a pin 15. The vertical frame 12 is provided with a first mounting hole 122. When the first connector 13 is connected to the vertical frame 12, the pin 15 passes through the first mounting hole 122 to fasten the first connector 13 to the vertical frame 12.
[0044] Specifically, after the first connecting end 131 of the first connector 13 is inserted into the first insertion slot 121 and the connection between the horizontal frame 11 and the vertical frame 12 is completed, the pin 15 passes through the first mounting hole 122 and the first connector 13 to form a mechanical lock, which improves the connection stability between the vertical frame 12 and the first connector 13. Even if the vertical frame 12 is subjected to external force, the first connector 13 and the vertical frame 12 can maintain a good connection.
[0045] Please see Figure 1 and Figure 2 The frame connection structure 10 also includes a second connector 16, which includes a third connector 161 and a fourth connector 162 that are disposed opposite to each other. The third connector 161 is connected to the horizontal frame 11, and the fourth connector 162 is connected to the vertical frame 12.
[0046] Specifically, firstly, the third connecting end 161 of the second connector 16 is connected to the horizontal frame 11, then the second connecting end 132 of the first connector 13 is inserted into the first insertion slot 121, and finally the fourth connecting end 162 of the second connector 16 is connected to the vertical frame 12 to complete the assembly of the frame connection structure 10. With the cooperation of the first connector 13 and the second connector 16, the connection stability between the horizontal frame 11 and the vertical frame 12 is improved.
[0047] Please see Figure 1 and Figure 4 The horizontal frame 11 is provided with a second mounting groove 113, the vertical frame 12 is provided with a second insertion groove 123, the third connecting end 161 is connected to the second mounting groove 113, and the fourth connecting end 162 is connected to the second insertion groove 123.
[0048] Specifically, the third connecting end 161 of the second connector 16 is installed in the second mounting slot 113 to match, and then the fourth connecting end 162 is inserted into the second insertion slot 123 to match, thereby completing the assembly of the frame connection structure 10, reducing assembly time and improving production efficiency.
[0049] Please refer to it again. Figure 4 A positioning part 163 is provided between the third connecting end 161 and the fourth connecting end 162. A second mounting hole 124 is provided on the vertical frame 12, and a third mounting hole 164 is provided on the second connecting end 132. When the positioning part 163 abuts against the groove of the second insertion groove 123, the second mounting hole 124 corresponds to the third mounting hole 164.
[0050] Specifically, during the assembly process of the frame connection structure 10, when the fourth connecting end 162 of the second connector 16 is inserted into the second insertion slot 123 and the positioning part 163 abuts against the groove of the second insertion slot 123 of the vertical frame 12, the third mounting hole 164 on the second connecting end 132 is aligned with the second mounting hole 124 on the vertical frame 12. The screw passes through the second mounting hole 124 and the third mounting hole 164 to securely connect the second connector 16 to the vertical frame 12, thereby avoiding misalignment and deviation during the assembly process of the vertical frame 12 and the horizontal frame 11, and improving the accuracy and efficiency of the assembly of the vertical frame 12 and the horizontal frame 11.
[0051] Please refer to it again. Figures 1 to 4The following is a brief description of the assembly steps of the frame connection structure 10 proposed in this embodiment: First, the first connector 13 is installed in the first mounting groove 111 of the horizontal frame 11 and the second connector 16 is installed in the second mounting groove 113 of the horizontal frame 11. Then, the first connecting end 131 of the first connector 13 is inserted into the first insertion groove 121 and the third connecting end 161 of the second connector 16 is inserted into the second insertion groove 123. Finally, the pin 16 passes through the first mounting hole 122 to fix the first connector 13 to the vertical frame 12, and the screw passes through the second mounting hole 124 to fix the second connector 15 to the vertical frame 12, so as to complete the assembly of the frame connection structure 10.
[0052] Please see Figure 5 The present invention also proposes a folding door and window, comprising: a hinge 20 and at least two frame connecting structures 10 as described above, wherein one frame connecting structure 10 is connected to one side of the hinge 20 and the other frame connecting structure 10 is connected to the other side of the hinge 20.
[0053] Specifically, the frame connection structure 10 is applied to folding doors and windows, so the beneficial effects of folding doors and windows are the same as the beneficial effects of the frame connection structure 10.
[0054] Compared with the prior art, the frame connection structure 10 proposed in this utility model has the end face of the vertical frame 12 abutting against the horizontal frame 11, changing the force from a point to a surface, avoiding the phenomenon of local stress concentration, and improving the load-bearing capacity of the frame connection structure 10 for large-sized door panels.
[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
