Detailed Implementation

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] Example

[0021] Please refer to Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides a flange connector for aluminum-plastic co-extruded doors and windows. The sealing gasket 17 is made of rubber. Two polygonal connecting blocks 5 are located on both sides of the fixing plate 11. The upper end of the profile 1 is provided with a threaded hole 13. A horizontal plate 14 is fixedly connected to one side of the flange 2. A through hole 15 is provided on the horizontal plate 14. A bolt 16 passes through the through hole 15. The bolt 16 cooperates with the threaded hole 13. By passing one end of the bolt 16 through the through hole 15 and threadedly connecting it to the threaded hole 13, the flange 2 and the profile 1 can be fixedly connected.

[0022] As a further implementation of this embodiment, such as Figures 1-5 As shown, the profile 1 has a slot 3, and the lower end of the flange 2 is fixedly connected to a block 4. The block 4 and the slot 3 cooperate with each other. A pair of polygonal connecting blocks 5 are fixedly connected in the slot 3. A connecting plate 6 is fixedly connected to one side of the flange 2. A bearing 7 is provided on the connecting plate 6. A threaded sleeve 8 is fixedly connected to the inner wall of the bearing 7. A threaded rod 9 is threadedly connected to the inner wall of the threaded sleeve 8. A limit plate 10 is fixedly connected to the lower end of the threaded rod 9. A fixing plate 11 is fixedly connected to the lower end of the limit plate 10. Sealing gaskets 17 are provided on both sides of the fixing plate 11. A limit groove 12 is provided on one side of the flange 2, and one end of the limit plate 10 is inserted into the limit groove 12. The limit groove 12 can play a certain limiting role for the limit plate 10.

[0023] In use, by inserting the locking block 4 into the locking groove 3 and then rotating the threaded sleeve 8, the rotation of the threaded sleeve 8 causes the threaded rod 9 to move downward, which in turn causes the limiting plate 10 to move downward. Under the limiting action of the limiting groove 12, the movement of the limiting plate 10 can be made more stable. The movement of the limiting plate 10 causes the fixing plate 11 and the sealing gasket 17 to move downward, which can make the sealing gasket 17 tightly squeezed and adhered to the two polygonal connecting blocks 5, thereby achieving a certain degree of sealing. This device can improve the sealing performance between the flange 2 and the profile 1, and prevent rainwater from flowing from one side of the profile 1 to the other side.

[0024] Specific working principle: in use, first insert the card block 4 into the card slot 3 and move to the appropriate position, then through the one end of bolt 16 is threaded through the hole 15 and is connected with the threaded hole 13, so that the flange 2 and the section bar 1 can be fixedly connected, then rotate the threaded sleeve 8, the threaded sleeve 8 rotates and drives the threaded rod 9 to move downward, in turn drives the limiting plate 10 to move downward, and under the limiting effect of the limiting groove 12, the limiting plate 10 can move more stably, the limiting plate 10 moves and drives the fixed plate 11 and the sealing gasket 17 to move downward, in turn can make the sealing gasket 17 and two polygonal connecting blocks 5 tightly extruded and fit, so that a certain sealing property can be achieved, through the device, the sealing property of the flange 2 and the section bar 1 can be improved, and rainwater can be prevented from flowing from one side of the section bar 1 to the other side.
