Technical Field
[0001] This application relates to the field of corner code device technology, and more specifically, to a corner code device for connecting aluminum-plastic doors and windows. Background Technology
[0002] During the installation of aluminum-plastic doors and windows, the connecting corner brackets play a crucial role in firmly connecting two perpendicular frame edges. The quality of the connecting corner brackets directly affects the stability, sealing performance, and overall lifespan of the door and window installation. Existing connecting corner brackets require significant manpower and time to align with the pre-set mounting holes on the frame during assembly, demanding a high level of skill from the installers. This can easily lead to installation quality issues due to improper operation. Furthermore, the fit between the connecting corner brackets and the door and window frames is not always tight enough, making them susceptible to external environmental factors during use, which can cause the connection to loosen. This, in turn, affects the normal opening and closing and sealing performance of the doors and windows, and in severe cases, even reduces the safety of the entire door and window system. Therefore, we propose an aluminum-plastic door and window connecting corner bracket device. Utility Model Content
[0003] 1. Technical problems to be solved The purpose of this application is to provide an aluminum-plastic door and window connecting corner bracket device, which solves the technical problems in the background art mentioned above. It realizes the design of fixing an elastic damping plate at the end of the integral corner bracket, embedding an injection film on the bottom surface, and inserting a rubber screw seat in a rectangular through groove. During assembly, the J-shaped elastic damping plate and the injection film damping allow the corner bracket to be stably inserted into the door and window frame. The positioning pin is accurately inserted into the preset hole, which quickly realizes the positioning of the door and window frame mounting hole and the screw hole of the screw seat. No complicated operation is required, which improves the installation efficiency and quality, ensures uniform gaps, and tightens the bolts after initial positioning. The elastic damping plate and the injection film increase friction and sealing, and the injection of glue can also reinforce and enhance stability, extend the service life of the door and window, and provide users with a comfortable and safe environment.
[0004] 2. Technical Solution This application provides an aluminum-plastic door and window connecting corner bracket device, comprising: an integral corner bracket, wherein the integral corner bracket is symmetrically provided with trapezoidal through grooves and rectangular through grooves along the corner line, a positioning pin for positioning and interlocking with the door and window frame is installed at the trapezoidal through groove of the integral corner bracket, a rubber screw seat is slidably inserted at the rectangular through groove of the integral corner bracket, and a through hole is opened at the rectangular through groove of the integral corner bracket, elastic damping plates can be detachably installed at both ends of the integral corner bracket, and an injection adhesive film is embedded at the bottom surface of the integral corner bracket.
[0005] By adopting the above technical solution, the integral corner bracket has trapezoidal and rectangular through slots at each right angle, realizing a symmetrical structure design along the diagonal. The trapezoidal through slots are used to install positioning pins for precise positioning and insertion with the door and window frames, ensuring accurate initial positioning. Rubber screw seats slide into the rectangular through slots, and the integral corner bracket has corresponding through holes to facilitate subsequent bolt fixing of the door and window frames. Elastic damping plates can be detachably installed at both ends of the integral corner bracket, which can achieve a slow insertion effect when the integral corner bracket is damped to the door and window frames. Combined with the glued film embedded in the bottom surface of the integral corner bracket, it effectively buffers and prevents loosening, enhancing sealing and stability. This structural design allows the components to work together during installation, enabling quick and stable connection at the corners of aluminum-plastic doors and windows, improving installation efficiency, ensuring connection quality, extending service life, and providing reliable support and connection for doors and windows.
[0006] Optionally, the overall corner bracket has a right-angle structure, and both sides of the surface are provided with strip grooves at the corners. The glue-filling film matches the shape of the overall corner bracket, and the glue-filling film is fixed with strip inserts that match the strip grooves and trapezoidal blocks that match the trapezoidal through grooves.
[0007] By adopting the above technical solution, the shape of the injection film matches that of the overall corner bracket, and the injection film is perfectly embedded into the bottom position of the overall corner bracket using strip inlays, trapezoidal blocks and rectangular plates, so that the injection film can be accurately embedded into the corresponding slot during installation, ensuring a tight fit between the injection film and the overall corner bracket, and further enhancing the strength and stability of the overall structure.
[0008] Optionally, both ends of the integral corner bracket are provided with concave grooves, and K-shaped reinforcing blocks are fixed to the inner walls of the concave grooves. A rectangular plate matching the concave grooves is fixed on the glue-injecting film.
[0009] By adopting the above technical solution, the matching design of the rectangular plate and the concave groove allows the glue-injecting film to be tightly combined with the overall corner bracket located in the concave groove during installation, forming a complete closed structure. During the glue injection process, the glue can fully fill the gap between the concave groove and the rectangular plate, further enhancing the stability and reliability of the entire overall corner bracket device.
[0010] Optionally, L-shaped guide bars are fixed on both sides of the trapezoidal through groove of the integral corner bracket, and rubber screw seats are slidably installed between the L-shaped guide bars. The rubber screw seats are provided with screw holes that match the through holes and guide grooves that match the L-shaped guide bars.
[0011] By adopting the above technical solution, when installing the rubber screw seat, the guide groove on the rubber screw seat slides along the L-shaped guide bar. This ensures that the rubber screw seat moves in the rectangular through groove in an accurate direction, avoiding installation difficulties or unstable connections caused by positional deviations. The screw hole, through hole and the pre-set mounting hole of the door and window frame match, so that the bolt can pass through and be tightened smoothly.
[0012] Optionally, each of the integral corner brackets has a convex groove at its end, the elastic damping sheet has a J-shaped structure and is fixed with a convex block that slides in match with the convex groove, and the convex block is threadedly connected to the integral corner bracket with two screws.
[0013] By adopting the above technical solution, the convex groove is designed to match the convex block on the elastic damping sheet and is fixed with a screw to realize the detachable installation of the elastic damping sheet. The elastic damping sheet has a J-shaped structure, which can provide sufficient elasticity to ensure that the elastic damping sheet can always provide good friction during the matching and insertion process with the door and window frame, so that the overall corner bracket can be stably and slowly inserted into the door and window frame.
[0014] Optionally, a spring is fixed to the inner wall of the trapezoidal groove, and the integral corner bracket has a through hole structure that matches the positioning pin at the trapezoidal groove.
[0015] By adopting the above technical solution, when one right-angled side of the overall corner bracket is inserted into the door and window frame, the spring will be compressed and generate elastic force, which will keep the positioning pin under pressure on the door and window frame, thereby ensuring a tight contact between the positioning pin and the door and window frame. When the positioning pin reaches the preset positioning hole of the door and window frame, the positioning pin achieves precise insertion and positioning, completing the initial positioning and insertion. This also allows the pre-drilled installation holes of the door and window frame to be quickly and accurately aligned with the screw holes of the rubber screw seat, thus facilitating the use of bolts for fixing and completing the quick and stable connection between the overall corner bracket and the door and window frame.
[0016] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. By fixing an elastic damping plate at each of the two right-angled ends of the integral corner bracket, embedding an adhesive pad into the bottom surface of the corner bracket through a specific structure, and inserting a rubber screw seat into a rectangular through groove, the integral corner bracket can be slowly and stably inserted into the door and window frame during the assembly process at the corner of the door and window frame. This is achieved by using the damping effect of the J-shaped elastic damping plate and the adhesive pad until the positioning pin is inserted into the preset positioning hole of the door and window frame. This allows for quick and accurate positioning of the mounting hole of the door and window frame with the screw hole of the rubber screw seat, without the need for complicated operation steps and professional tools. This significantly improves installation efficiency, reduces installation difficulty, and effectively avoids installation failure or unstable connection problems that may be caused by positioning deviation. It also ensures uniform gaps in the installed doors and windows, improving the overall quality and performance of the doors and windows. 2. After initial positioning, bolts are passed through the through holes and tightened into the screw holes, achieving a secure connection between the overall corner bracket and the door / window frame. The presence of elastic damping sheets and adhesive pads increases the friction and sealing ability of the connection points, preventing loosening due to various external forces during use. An adhesive injection process can also be used to inject glue into each connection point, further enhancing the stability and sealing of the connection. This allows the doors and windows to maintain good performance over long-term use, reducing the frequency of maintenance and replacement, extending their service life, and providing users with a more comfortable and safer living environment.

[0018] The present application will be further described in detail below with reference to the accompanying drawings. Reference Figures 1 to 4 This application provides an aluminum-plastic door and window connecting corner bracket device, comprising: an integral corner bracket 1, wherein the integral corner bracket 1 is symmetrically provided with trapezoidal through grooves 12 and rectangular through grooves 13 along the corner line; a positioning pin 2 for positioning and insertion with the door and window frame is installed at the trapezoidal through groove 12 of the integral corner bracket 1; a rubber screw seat 4 is slidably inserted at the rectangular through groove 13 of the integral corner bracket 1, and a through hole 131 is opened at the rectangular through groove 13 of the integral corner bracket 1; elastic damping sheets 3 can be detachably installed at both ends of the integral corner bracket 1; and an adhesive film 5 is embedded in the bottom surface of the integral corner bracket 1. The integral corner bracket 1 is provided with trapezoidal through grooves 12 and rectangular through grooves 13 at each right angle, realizing a symmetrical structural design along the diagonal of the integral corner bracket 1. The trapezoidal through groove 12 is used for... The positioning pin 2 is used for precise positioning and insertion with the door and window frame to ensure accurate initial position. The rubber screw seat 4 is slidably inserted into the rectangular through groove 13, and the overall corner bracket 1 has corresponding through holes 131 to facilitate subsequent bolt fixing of the door and window frame. The elastic damping plates 3 can be detachably installed at both ends of the overall corner bracket 1, which can achieve a slow insertion effect when the overall corner bracket 1 is connected to the door and window frame. Together with the glued film 5 embedded on the bottom surface of the overall corner bracket 1, it effectively buffers and prevents loosening, enhancing sealing and stability. This structural design allows the components to work together during installation, enabling quick and stable connection at the corner of aluminum-plastic doors and windows, improving installation efficiency, ensuring connection quality, extending service life, and providing reliable support and connection for doors and windows.
[0019] Reference Figure 2 and Figure 4 The overall corner bracket 1 has a right-angle structure, and both sides of the surface have strip grooves 11 at the corners. The shape of the glue-injecting film 5 matches the shape of the overall corner bracket 1. The glue-injecting film 5 is fixed with strip-shaped inserts 51 that match the strip grooves 11 and trapezoidal blocks 52 that match the trapezoidal through grooves 12. The glue-injecting film 5 matches the shape of the overall corner bracket 1, and the glue-injecting film 5 is perfectly embedded in the bottom position of the overall corner bracket 1 by using strip-shaped inserts 51, trapezoidal blocks 52 and rectangular plates 53. This allows the glue-injecting film 5 to be accurately embedded into the corresponding grooves during installation, ensuring a tight fit between the glue-injecting film 5 and the overall corner bracket 1, and further enhancing the strength and stability of the overall structure.
[0020] Reference Figure 2 and Figure 3Both ends of the overall corner bracket 1 are provided with concave grooves 14. K-shaped reinforcing blocks 141 are fixed to the inner wall of the concave grooves 14. A rectangular plate 53 matching the concave grooves 14 is fixed on the glue injection film 5. The matching design of the rectangular plate 53 and the concave grooves 14 allows the glue injection film 5 to be tightly combined with the overall corner bracket 1 at the concave grooves 14 during installation, forming a complete closed structure. During the glue injection process, the glue can be fully filled into the gap between the concave grooves 14 and the rectangular plate 53, further enhancing the stability and reliability of the entire device of the overall corner bracket 1.
[0021] Reference Figure 2 and Figure 4 The overall corner bracket 1 is fixed with L-shaped guide strips 132 on both sides of the inner wall of the trapezoidal through groove 12. Rubber screw seats 4 are slidably installed between the L-shaped guide strips 132. The rubber screw seats 4 are provided with screw holes 42 that match the through holes 131 and guide grooves 41 that match the L-shaped guide strips 132. When installing the rubber screw seats 4, the guide grooves 41 on the rubber screw seats 4 slide along the L-shaped guide strips 132. This can ensure that the movement direction of the rubber screw seats 4 in the rectangular through groove 13 is accurate and avoids installation difficulties or unstable connections caused by position deviation. The screw holes 42, through holes 131 and the preset installation holes of the door and window frames match, so that bolts can be smoothly passed through and tightened.
[0022] Reference Figure 2 and Figure 3 The corner bracket 1 has convex grooves 15 at each end. The elastic damping plate 3 has a J-shaped structure and is fixed with a convex block 32 that slides and matches the convex groove 15. The convex block 32 is threadedly connected to the corner bracket 1 by two screws 31. The convex groove 15 is designed to match the convex block 32 on the elastic damping plate 3 and is fixed by screws 31 to realize the detachable installation of the elastic damping plate 3. The elastic damping plate 3 has a J-shaped structure, which can provide sufficient elasticity to ensure that the elastic damping plate 3 can always provide good friction during the matching and insertion process with the door and window frame, so that the corner bracket 1 can be stably and slowly inserted into the door and window frame.
[0023] Reference Figure 1 and Figure 2A spring 21 is fixed to the inner wall of the trapezoidal groove 12 and the positioning pin 2. The integral corner bracket 1 has a through hole structure that matches the positioning pin 2 at the trapezoidal groove 12. When one right-angle side of the integral corner bracket 1 is inserted into the door and window frame, the spring 21 will be compressed and generate elastic force, which will make the positioning pin 2 always maintain pressure on the door and window frame, thereby ensuring a tight contact between the positioning pin 2 and the door and window frame. When the positioning pin 2 reaches the preset positioning hole of the door and window frame, the positioning pin 2 achieves precise insertion and positioning, completes the initial positioning and insertion, and enables the installation hole pre-opened in the door and window frame to be quickly and accurately aligned with the screw hole 42 of the rubber screw seat 4, thereby facilitating the use of bolts for fixing and completing the quick and stable connection between the integral corner bracket 1 and the door and window frame.
[0024] Working principle: During installation, the elastic damping plates 3 are slidably installed at the ends of the two right-angled sides of the integral corner bracket 1 using the convex grooves 15, and fixed and limited by two screws 31. The glued film 5 is embedded into the bottom surface of the integral corner bracket 1 using the strip-shaped insert 51, trapezoidal block 52, and rectangular plate 53. Then, the two rubber screw seats 4 are guided and inserted into the rectangular through groove 13 along the L-shaped guide strip 132 to complete the preparation work. Then, the two right-angled sides of the integral corner bracket 1 are connected to the corners of the two door and window frames respectively. The J-shaped elastic damping plates 3 create a damping effect, allowing the integral corner bracket 1 to be slowly and stably inserted into the door and window frames. When the positioning pin 2 moves... When the positioning pin 2 reaches the position of the pre-drilled positioning hole on the door and window frame, the spring 21 enables the positioning pin 2 to be precisely positioned with the door and window frame, completing the initial positioning and insertion. This also allows the pre-drilled mounting hole on the door and window frame to be aligned with the screw hole 42 of the rubber screw seat 4 and the through hole 131 of the integral corner bracket 1. The bolt is then passed through the through hole 131 and tightened with the screw hole 42, thereby completing the quick and stable connection between the integral corner bracket 1 and the door and window frame. Under the action of the elastic damping sheet 3 and the glue injection sheet 5, the integral corner bracket 1 increases the friction of the connection part and prevents loosening. Furthermore, the glue injection process can be used to inject glue into each connection part to further improve the stability and sealing of the connection.
