Description

Technical Field

[0001] The utility model relates to the technical field of door and window angle brackets, in particular to an angle bracket used for sealing connections of doors and windows. Background Art

[0002] Doors and windows are essential components of buildings, providing ventilation, lighting, sound insulation, thermal insulation, and protection. They not only provide a channel for indoor and outdoor communication but also play a key role in energy efficiency and comfort. To ensure structural stability and a good seal against the infiltration of air, moisture, and dust, door and window joints, especially at corners, require sealing brackets. Corner brackets strengthen the connection strength of the door and window frames, maintain angle accuracy, and enhance overall sealing performance and wind pressure resistance, thereby extending the service life of doors and windows and improving user safety and comfort. Therefore, the sealing brackets of door and window joints are critical components for ensuring the functionality and durability of doors and windows.

[0003] Traditional corner brackets for sealing doors and windows are fixed at the corners of the door and window frames to enhance structural stability and sealing performance. When using them, first select the type and size of the bracket that matches the door and window frame, ensuring that the material and design are suitable for the specific application environment. During installation, position the bracket at the joint of the frame and secure it with screws, rivets, or welding. If necessary, add a cover plate for enhanced aesthetics and protection. The installation of the corner bracket maintains the angular accuracy of the door and window frame, reduces the risk of loosening, deformation, and poor sealing, and effectively improves the overall performance and service life of the door and window.

[0004] Traditional corner brackets for sealing doors and windows are mostly made of ordinary aluminum alloy or plastic. The fatigue performance of the material will weaken over time and cannot continuously provide efficient connection strength, thus affecting the overall structural strength and safety of the doors and windows. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a corner bracket for sealing connections of doors and windows, aiming to improve traditional door and window corner brackets, which cannot continuously provide efficient connection strength, thereby affecting the overall structural strength and safety of doors and windows.

[0007] Furthermore, the fixing assembly includes a semicircular thread groove, which is opened inside the upper angle bracket body, and an arcuate thread groove is opened inside the lower angle bracket body, and the internal thread of the upper angle bracket body is connected to an expansion bolt.

[0008] Furthermore, vertical through grooves are provided inside the upper corner code body and the lower corner code body, horizontal through grooves are provided inside the upper corner code body and the lower corner code body, through holes are provided inside the top cover and the bottom cover, and V-shaped grooves are provided inside the top cover and the bottom cover.

[0009] Furthermore, the sliding column and the guide column are both arranged inside the upper angle bracket body and the lower angle bracket body, and the sliding column and the guide column are used to guide the movement of the top cover and the bottom cover.

[0010] Furthermore, a top corner is fixedly connected to the outer wall of the upper corner bracket body, and one side of the outer wall of the top corner is fixedly connected to the outer wall of the lower corner bracket body.

[0011] Furthermore, reinforcing ribs are provided inside the upper corner code body and the lower corner code body, and the reinforcing ribs are used to improve the strength of the upper corner code body and the lower corner code body.

[0012] Furthermore, a sealing strip placement groove is provided between the upper corner bracket body and the lower corner bracket body, and the sealing strip placement groove is used for placing an elastic sealing member.

[0013] Furthermore, the through hole is provided above the transverse through groove, and the through hole is used to facilitate the circulation of the glue.

The through hole 11 is provided above the transverse through groove 9. The through hole 11 is used to facilitate the circulation of glue.

[0026] Working principle: When the angle code for sealing the doors and windows is needed, first place the top cover 2 on top of the upper angle code body 1, then place the bottom cover 3 under the lower angle code body 6, and insert the top of the sliding column 4 into the inside of the guide column 5 to achieve the connection, then place the elastic seal in the sealing strip placement groove 14, and then place it inside the door and window, then drive the expansion bolt 703 to rotate between the upper angle code body 1 and the lower angle code body 6, and through the semicircular thread groove 702 inside the upper angle code body 1 and the arc thread groove 701 inside the lower angle code body 6, then align the expansion bolt 703 with the hole on the wall, start to slowly rotate the screwdriver to make the expansion bolt 703 enter the hole, when the expansion bolt 703 is close to being immersed in the cavity, the force It will gradually increase in size, and the expansion bolts 703 will begin to expand and generate friction inside the wall, thereby fixing the angle bracket. At the same time, the expansion of the expansion bolts 703 will further push the upper angle bracket body 1 and the lower angle bracket body 6 to expand to both sides, thereby fixing the upper angle bracket body 1 and the lower angle bracket body 6 to the inside of the door and window. In this process, the top cover 2 and the bottom cover 3 are fixed to the outer walls of the upper angle bracket body 1 and the lower angle bracket body 6 through the protrusions on one side of the outer wall of the top cover 2 and the bottom cover 3, thereby further providing strength to the angle bracket through the sliding columns 4 and the guide columns 5 on the outer walls of the top cover 2 and the bottom cover 3. At this time, the top angles 10 of the outer walls of the upper angle bracket body 1 and the lower angle bracket body 6 will press against the turning point of the door and window, and cooperate with the reinforcing ribs 13 inside the upper angle bracket body 1 and the lower angle bracket body 6 to provide stable strength.

[0027] In addition, when injecting glue, the glue will flow along the vertical through groove 8 and the horizontal through groove 9. At this time, when the glue flows to the inside of the horizontal through groove 9, it will also flow through the through hole 11 to the inside of the top cover 2 and the bottom cover 3, thereby stably connecting the top cover 2, the bottom cover 3, the upper corner code body 1 and the lower corner code body 6. The glue continues to flow to the inside of the V-shaped groove 12, thereby fixing the corner code to the inside of the door and window, and at the same time cooperates with the elastic seal inside the sealing strip placement groove 14 to achieve a waterproof effect.
