Description

Technical Field

[0001] This utility model belongs to the technical field of corner brackets, specifically relating to an aluminum alloy door and window glue-injection type corner bracket. Background Technology

[0002] Aluminum alloy door and window injection-type corner brackets are special structural components used for corner connections in doors and windows. They are mainly used to enhance the strength and sealing of door and window frames. They are usually made of aluminum alloy and are tightly bonded to the door and window profiles through an injection process. The core feature of injection-type corner brackets is that a special adhesive is injected into the inside of the corner bracket or the part in contact with the profile. After curing, a high-strength connection is formed, effectively improving the overall stability and deformation resistance of doors and windows. Compared with traditional mechanical connection methods, injection-type corner brackets have higher connection strength and durability, and are suitable for high-end aluminum alloy door and window systems with high requirements for sealing and strength.

[0003] However, due to the differences in thickness of existing aluminum alloy doors and windows, the required corner bracket thickness also varies. Currently, corner brackets are all integrally molded parts with fixed thickness dimensions, which means that these corner brackets still need to be produced according to different aluminum alloy doors and windows, resulting in poor versatility. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum alloy door and window glue injection type corner bracket to solve the problem mentioned in the background art that the existing aluminum alloy doors and windows have different thicknesses, which leads to different requirements for the thickness of the corner brackets. Currently, the corner brackets are all integrally formed workpieces with fixed thickness dimensions, which means that these corner brackets still need to be produced according to different aluminum alloy doors and windows, resulting in poor versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy door and window glue-injection type corner bracket, including a corner bracket body and cover plates disposed on both sides of the outer edge of the corner bracket body;

[0006] The cover plate is provided with an outflow adhesive groove, the corner bracket body is provided with two pin grooves, and a fixing block is provided on each side of the corner bracket body, with fixing screw holes provided on the fixing blocks;

[0007] The corner bracket body is composed of a middle corner bracket and outer corner brackets respectively disposed on both sides. Semicircular fixing ears are provided on both sides of the middle and outer corner brackets. Separating blocks are provided at axially symmetrical positions on both the middle and outer corner brackets. Circular fixing ears are provided on the separating blocks. Through holes are provided on the semicircular and circular fixing ears of one side of the outer corner bracket. A slot is provided in the middle of the through hole, and a filling groove is provided on the outer side of the through hole. Screws can be installed inside these through holes, and the screws are provided with circular locking blocks. Threaded sleeves are provided on the semicircular and circular fixing ears of the other side of the outer corner bracket. Four sliding protrusions are provided on the outer side of the threaded sleeves. Through holes are also provided on the semicircular and circular fixing ears of the middle corner bracket, and four sliding grooves are provided on the edges of these through holes.

[0008] Preferably, the circular locking block is welded to the screw, the circular locking block can be locked inside the slot, the slot can limit the position of the circular locking block and the screw, and the screw can rotate through the circular locking block inside the slot.

[0009] Preferably, the screw head can be installed inside the filling groove, and the filling groove is set so that the screw thread head is flush with the outer surface of the outer corner bracket. The screw is threadedly connected to the threaded sleeve, and one end of the threaded sleeve is welded to the outer corner bracket on the other side.

[0010] Preferably, the sliding protrusion is welded to the threaded sleeve, the sliding protrusion is cross-shaped and disposed on the outside of the threaded sleeve, the sliding protrusion can slide in the sliding groove, and the sliding groove can restrict the sliding direction of the sliding protrusion and the threaded sleeve.

[0011] Preferably, the length of the sliding groove is less than the length of the through hole on the middle layer corner bracket. The threaded sleeve is inserted into the through hole on the middle layer corner bracket. The threaded sleeve can only slide within the through hole in a limited manner through the sliding protrusion. The cooperation between the sliding groove and the sliding protrusion can prevent the threaded sleeve from detaching from the middle layer corner bracket.

[0012] Preferably, the separator block, the semi-circular fixing ear, and the circular fixing ear are all integrally formed with the middle layer corner bracket and the outer layer corner bracket. The distance between the outer layer corner bracket and the middle layer corner bracket can be adjusted by rotating the screw, thereby changing the width of the corner bracket body.

[0013] Preferably, the fixing block and the middle-layer corner bracket are integrally formed. The fixing screw holes on the fixing block are used to install and fix the corner bracket body to the external aluminum alloy door frame. Fixing glue grooves are provided on both sides of the fixing screw holes, and the fixing glue grooves can guide glue into the fixing screw holes.

[0014] Compared with the prior art, this utility model provides an aluminum alloy door and window glue-injection type corner bracket, which has the following beneficial effects:

[0015] The design incorporates a circular locking block, screw, locking slot, filling groove, outer corner bracket, middle corner bracket, threaded sleeve, sliding protrusion, sliding groove, and through hole. The circular locking block and locking slot work together to allow the screw to rotate freely within the through hole. The filling groove design ensures a smooth and even fit between the screw head and the outer corner bracket surface, allowing the cover plate to tightly conform to the outer corner bracket. The threaded sleeve, through the smooth sliding of the sliding protrusion within the sliding groove, combined with the screw's rotation adjustment, achieves precise control of the distance between the outer and middle corner brackets. This allows for flexible adjustment of the overall width of the corner bracket body, enabling it to adapt to profile cavities of different sizes, greatly improving the corner bracket's versatility. The limiting sliding design of the sliding protrusion within the sliding groove ensures stable operation of the threaded sleeve and effectively prevents component separation, ensuring the integrity and reliability of the overall structure.

[0016] By setting a fixed adhesive channel, the injected adhesive can naturally penetrate into the fixed screw hole, forming a uniform adhesive film filling during the screw screwing process. This dual mechanical-adhesive composite fixing method not only significantly improves the strength and durability of the connection part, but also effectively blocks the intrusion of water vapor and rainwater through the sealing adhesive layer, preventing screw corrosion, thereby greatly enhancing the long-term stability and sealing performance of the corner structure of doors and windows.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 The aluminum alloy door and window glue-injection type corner bracket shown includes a corner bracket body 1 and cover plates 2 disposed on both sides of the outer side of the corner bracket body 1.

[0026] The cover plate 2 is provided with an outflow adhesive groove 7, the corner bracket body 1 is provided with two pin grooves 3, and a fixing block 8 is provided on each side of the corner bracket body 1. The fixing block 8 is provided with a fixing screw hole 4.

[0027] The corner bracket body 1 is composed of a middle corner bracket 5 and outer corner brackets 6 respectively set on both sides. The middle corner bracket 5 and the outer corner bracket 6 are respectively provided with semi-circular fixing ears 16. The middle corner bracket 5 and the outer corner bracket 6 are respectively provided with partition blocks 11 at axially symmetrical positions. The partition blocks 11 are provided with circular fixing ears 14. The semi-circular fixing ears 16 and circular fixing ears 14 of one side of the outer corner bracket 6 are provided with through holes 15. The middle position of the through hole 15 is provided with a slot 12, and the outer position of the through hole 15 is provided with a filling groove 13. Screws 18 can be installed in these through holes 15. The screws 18 are provided with circular locking blocks 10. The semi-circular fixing ears 16 and circular fixing ears 14 of the other side of the outer corner bracket 6 are provided with threaded sleeves 20. The outer side of the threaded sleeves 20 is provided with four sliding protrusions 19. The semi-circular fixing ears 16 and circular fixing ears 14 of the middle corner bracket 5 are also provided with through holes 15. The edges of these through holes 15 are respectively provided with four sliding grooves 17.

[0028] In this embodiment, the aluminum alloy door and window injection-type corner bracket involves injecting a special structural adhesive into the contact surface between the corner bracket and the profile. This transforms the corner connection from traditional mechanical fixing to a composite connection method combining adhesive bonding and mechanical bonding. Once the adhesive cures, a high-strength adhesive layer forms between the corner bracket and the aluminum profile. This not only enhances the shear and tensile strength of the corner but also fills the tiny gaps between the profile and the corner bracket, thereby improving the overall stability and sealing of the door and window. This ensures that the corners are less prone to damage when the door and window frame is subjected to wind pressure, temperature changes, or daily opening and closing forces. To prevent loosening or deformation and extend service life, the corner bracket is used as follows: First, install the cover plate 2 on both sides of the corner bracket body 1. Then, precisely insert the corner bracket body 1 into the cavity of the aluminum alloy profile, ensuring that the contact surface between the corner bracket body 1 and the profile is tightly fitted. Use a dedicated glue injection device to inject high-strength structural adhesive through the outflow glue groove 7 on the cover plate 2 into the preset glue injection hole of the corner bracket or the gap between the profile and the corner bracket. After the glue injection is completed, the adhesive will cure naturally or be accelerated by heating, ultimately forming a strong connection.

[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the circular locking block 10 is welded to the screw 18. The circular locking block 10 can be locked inside the locking groove 12. The locking groove 12 can limit the position of the circular locking block 10 and the screw 18. The screw 18 can rotate inside the locking groove 12 through the circular locking block 10. The screw head of the screw 18 can be installed inside the filling groove 13. The filling groove 13 is set so that the thread head of the screw 18 is flush with the outer surface of the outer angle bracket 6. The screw 18 is threadedly connected to the threaded sleeve 20. One end of the threaded sleeve 20 is welded to the outer angle bracket 6 on the other side. The sliding protrusion 19 is welded to the threaded sleeve 20. The sliding protrusion 19 is cross-shaped and set on the outside of the threaded sleeve 20. The sliding protrusion 19 can slide in the sliding groove 1. The sliding groove 17 restricts the sliding direction of the sliding protrusion 19 and the threaded sleeve 20. The length of the sliding groove 17 is less than the length of the through hole 15 on the middle layer corner bracket 5. The threaded sleeve 20 is inserted into the through hole 15 on the middle layer corner bracket 5. The threaded sleeve 20 can only slide in a limited manner inside the through hole 15 through the sliding protrusion 19. The cooperation between the sliding groove 17 and the sliding protrusion 19 can prevent the threaded sleeve 20 from detaching from the middle layer corner bracket 5. The separator block 11, the semi-circular fixing ear 16 and the circular fixing ear 14 are all integrally formed with the middle layer corner bracket 5 and the outer layer corner bracket 6. The distance between the outer layer corner bracket 6 and the middle layer corner bracket 5 can be adjusted by rotating the screw 18, thereby changing the width of the corner bracket body 1.

[0030] Preferably, the circular locking block 10, screw 18, locking groove 12, filling groove 13, outer corner bracket 6, middle corner bracket 5, threaded sleeve 20, sliding protrusion 19, sliding groove 17, and through hole 15 are configured. The circular locking block 10 and locking groove 12 cooperate to allow the screw 18 to rotate within the through hole 15. The filling groove 13 ensures the flatness of the screw head and the outer surface of the outer corner bracket 6, allowing the cover plate 2 to fit against the outer corner bracket 6. The threaded sleeve 20 can slide on the sliding groove 17 via the sliding protrusion 19. By rotating the screw 18, the distance between the outer corner bracket 6 and the middle corner bracket 5 can be precisely adjusted, thereby adjusting the overall width of the corner bracket body 1. This allows the corner bracket body 1 to adapt to the assembly requirements of different profile cavities. The limiting sliding of the sliding protrusion 19 within the sliding groove 17 effectively prevents the threaded sleeve 20 from dislodging from the through hole 15, ensuring the integrity of the component structure.

[0031] like Figure 2 and Figure 4 As shown, the fixing block 8 and the middle corner bracket 5 are integrally formed. The fixing screw hole 4 on the fixing block 8 is used to install and fix the corner bracket body 1 to the external aluminum alloy door frame. Fixing glue grooves 9 are provided on both sides of the fixing screw hole 4. The fixing glue grooves 9 can guide the glue into the fixing screw hole 4.

[0032] Preferably, by setting the fixed glue channel 9, when the structural adhesive is injected into the gap between the corner bracket body 1 and the profile through the external glue channel 7, some of the adhesive can naturally seep into the fixed screw hole 4 along the fixed glue channel 9. During the process of screw 18 being screwed into the fixed screw hole 4, the adhesive will evenly fill the gap between screw 18 and the inner wall of the screw hole. After curing, a double mechanical-adhesive composite fixation is formed. This design not only enhances the connection strength between the fixing block 8 and the external aluminum alloy door frame, but also effectively prevents rainwater or moisture from entering the gap of the screw 18 connection, avoids corrosion of the screw 18, and further improves the structural stability and sealing performance of the corner of the door and window in long-term use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
