[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Please refer to the appendix. Figures 1-6 The V-shaped expansion injection corner bracket provided by this utility model is used to connect the first aluminum profile 1 and the second aluminum profile 2. It includes a hook corner 3 and a base assembly. The base assembly is slidably connected to the inside of the hook corner 3. An expansion injection assembly is provided between the base assembly and the hook corner 3. A snap-fit ​​assembly is provided between the hook corner 3 and the first aluminum profile 1 and the second aluminum profile 2.

[0022] The base assembly includes two V-shaped bases 4. The bottom surfaces of the two V-shaped bases 4 are provided with a number of anti-slip teeth 5. The anti-slip teeth 5 abut against the inner surface of the first aluminum profile 1 and the inner surface of the second aluminum profile 2. The top surfaces of the two V-shaped bases 4 are symmetrically provided with base connection holes 6. Connecting rods 7 are inserted into the base connection holes 6 on the two V-shaped bases 4. Specifically, under the action of the insertion of the connecting rods 7, the two V-shaped bases 4 can slide stably on the inside of the hook corner 3, and the two V-shaped bases 4 can be stably connected and will not loosen.

[0023] The expansion injection assembly includes a threaded hole 9, which is located at the center of the top of the hook angle 3. Reinforcing ribs 10 are fixed at the center of the tops of the two V-shaped bases 4, forming a gap 13 between the opposite ends of the two reinforcing ribs 10. The gap 13 is located directly below the threaded hole 9. The expansion injection assembly also includes screws 12. Semicircular holes 11 are symmetrically provided at the splicing ends of the first aluminum profile 1 and the second aluminum profile 2. The end of the screw 12 passes through the two semicircular holes 11 and the threaded hole 9 in sequence. The surface of the screw 12 is threadedly connected to the wall of the threaded hole 9. Specifically, the screw 12 can move when rotated, and when the end of the screw 12 moves into the insertion gap 13, it can... Two reinforcing ribs 10 are used to open up the two V-shaped bases 4, allowing the two V-shaped bases 4 to slide in opposite directions, thereby achieving the function of expansion. After the two V-shaped bases 4 are opened, they will be tightly attached to the inner surfaces of the first aluminum profile 1 and the second aluminum profile 2. Even if there are no gaps inside the aluminum profile, the installation accuracy is high, making the connection and installation of the aluminum profile more secure. The splice area is perfectly fitted, flat and smooth, beautiful and practical. Adhesive is then injected in the middle to fill the gaps inside the first aluminum profile 1 and the second aluminum profile 2, that is, to bond the corner bracket to the aluminum profile together, which makes the stability better. Overall, the tightness and airtightness of the metal doors and windows are improved, and the quality of the doors and windows is further improved.

[0024] The snap-fit ​​assembly includes snap-fit ​​holes 14, which are symmetrically located on both sides of the splicing end of the first aluminum profile 1 and the second aluminum profile 2. Two hooks 8 are symmetrically fixed to the top of the hook 3 on both sides. The two hooks 8 can snap into the two snap-fit ​​holes 14. Specifically, when the screw 12 is turned, the hook 3 and the two V-shaped bases 4 will slide open relative to each other, allowing the two hooks 8 to snap into the snap-fit ​​holes 14, thus completing the installation. Figure 6 (As shown).

[0025] The usage process of this utility model is as follows: The splicing ends of the first aluminum profile 1 and the second aluminum profile 2 are assembled at a 45-degree angle to form a right angle. When installation is required, one end of the corner bracket is inserted into the first aluminum profile 1, and then the other end of the corner bracket is inserted into the second aluminum profile 2, so that the splicing ends of the first aluminum profile 1 and the splicing ends of the second aluminum profile 2 are joined together, and the semi-circular hole 11 on the first aluminum profile 1 and the semi-circular hole 11 on the second aluminum profile 2 are joined together to form an installation hole. Adhesive is injected from the installation hole and the threaded hole 9, and then the screw 12 is inserted and rotated. The screw 12 moves, so that the end of the screw 12 presses against the two reinforcing ribs 10, thus making the two V-shaped bases 4 open and tight. The first aluminum profile 1 and the second aluminum profile 2 are attached to their inner surfaces. Even if there are no gaps inside the aluminum profiles, the installation is highly accurate, making the connection and installation of the aluminum profiles more secure. The splice appears seamless, flat and smooth, which is both beautiful and practical. At this time, the injected adhesive flows into the middle gap, filling the gap inside the first aluminum profile 1 and the second aluminum profile 2, thus bonding the corner bracket to the aluminum profile. This results in better stability and improves the overall tightness and airtightness of the metal doors and windows, further enhancing the quality of the doors and windows. When the screw 12 is turned, the hook 3 and the two V-shaped bases 4 will slide open relative to each other, allowing the two upper hooks 8 to engage in the engagement holes 14, thus completing the installation.

[0026] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
