[0002] According to the search, a corner bracket for connecting aluminum profiles of metal doors and windows with announcement number CN217538446U is provided. It includes a first profile and a second profile, which are connected by a connector and are arranged perpendicularly. The connector includes a base block and a corner piece, which is snapped onto the base block.

[0003] Although the aforementioned utility model patent only requires drilling a round hole in one of the two sets of profiles, thus avoiding drilling holes in both sets of profiles and greatly improving processing efficiency and shortening processing time, the drawback of this type of corner bracket is that the base is a whole, and there will be a gap between the base and the inner wall of the aluminum profile after installation. It cannot fill the gap inside the connection part of the aluminum profile, the installation accuracy is not high enough, and there is no glue injection function, which is not conducive to long-term stable use. Further improvements are needed.

[0004] Therefore, it is necessary to invent a V-shaped eccentric expansion glue injection corner code. Utility Model Content

[0005] To address this issue, the present invention provides a V-shaped eccentric expansion injection corner bracket to solve the problems mentioned in the background section.

[0007] The base assembly includes two V-shaped bases. The bottom surfaces of the two ends of each V-shaped base are provided with a number of anti-slip teeth, which abut against the inner surface of the first aluminum profile and the inner surface of the second aluminum profile.

[0008] The eccentric expansion injection assembly includes a threaded hole, which is opened on one side of the hook corner. Reinforcing ribs are fixed on one side of the top of the two V-shaped bases. A gap is formed between the opposite ends of the two reinforcing ribs, and the gap is located directly below the threaded hole.

[0009] The eccentric expansion injection assembly also includes a screw. The splicing end of the second aluminum profile has an installation hole. The end of the screw passes through the installation hole and the threaded hole in sequence, and the surface of the screw is threadedly connected to the wall of the threaded hole.

[0010] Preferably, the top two ends of the V-shaped base are symmetrically provided with base connection holes, and a connecting rod is inserted into the base connection holes on the two V-shaped bases.

[0011] Preferably, the snap-fit ​​assembly includes snap-fit ​​holes, which are symmetrically opened on both sides of the splicing end of the first aluminum profile and the second aluminum profile. The top of the hook corner is symmetrically fixed with upper hooks on both sides, and the two upper hooks can be snapped into the two snap-fit ​​holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. By using the first aluminum profile, second aluminum profile, hook, base assembly, eccentric expansion injection assembly and snap-fit ​​assembly in combination, the aluminum profile connection and installation is more secure. The splice position is perfectly sealed, flat and smooth, beautiful and practical.

[0022] 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.

[0023] Please refer to the appendix. Figures 1-6 The V-shaped eccentric 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 eccentric 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.

[0024] 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.

[0025] The eccentric expansion injection assembly includes a threaded hole 9, which is located on one side of the top of the hook angle 3. Reinforcing ribs 10 are fixed to one side of the top of each 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 eccentric expansion injection assembly also includes a screw 12. A mounting hole 11 is provided at the splicing end of the second aluminum profile 2. The end of the screw 12 passes through the mounting hole 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. When the end of the screw 12 moves into the insertion gap 13, the two reinforcing ribs 10 can open the two V-shaped bases 4, allowing the two V-shaped bases 4 to... The reverse sliding mechanism expands the two V-shaped bases 4, ensuring they fit snugly against the inner surfaces of the first aluminum profile 1 and the second aluminum profile 2. This ensures a tighter connection even without gaps between the aluminum profiles, resulting in a smooth, aesthetically pleasing, and practical finish. Adhesive is then injected to fill the gaps between the first and second aluminum profiles, effectively bonding the corner bracket to the aluminum profiles for enhanced stability. This improves the overall tightness and airtightness of the metal doors and windows, further enhancing their quality. Furthermore, the eccentric design only requires one mounting hole 11 on the second aluminum profile 2; no hole is needed on the first aluminum profile 1. Figure 6 As shown in the figure, it saves a hole-making process and labor, and the first aluminum profile 1 is flat and looks good, which is conducive to cost reduction and efficiency improvement;

[0026] 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).

[0027] 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 second aluminum profile 2 are joined together. Then, adhesive is injected from the mounting hole 11 and the threaded hole 9. Then, the screw 12 is inserted and rotated. The screw 12 moves, causing the end of the screw 12 to press against the two reinforcing ribs 10, so that the two V-shaped bases 4 are spread open and 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 is highly accurate, making the connection and installation of the aluminum profile more secure. The splice appears seamless, flat and smooth, beautiful and practical. At this time, the injected adhesive flows into the middle gap, that is, fills the gap between the first aluminum profile 1 and the second aluminum profile 2, that is, it sticks the corner bracket to the aluminum profile together, which makes the stability better. Overall, it improves the tightness and airtightness of the metal doors and windows, and the quality of the doors and windows is further improved. When the screw 12 is turned, the hook 3 and the two V-shaped bases 4 will slide open relative to each other, so that the two upper hooks 8 can be engaged in the engagement hole 14, thus completing the installation.

[0028] Furthermore, through the eccentric structure design, only one mounting hole 11 needs to be drilled on the second aluminum profile 2, and the first aluminum profile 1 does not need to be drilled (e.g. Figure 6 As shown in the figure, it saves a hole-making process and labor, and the first aluminum profile 1 is flat and looks good, which is conducive to cost reduction and efficiency improvement.
