Description

Technical Field

[0001] This utility model relates to the field of door and window corner assembly technology, specifically to a corner assembly component for doors and windows. Background Technology

[0002] In architecture, a window is an opening in a wall or roof to allow light or air to enter a room. Corner brackets for doors and windows, also known as triangular connectors, are essential components in door and window assembly. Their principle utilizes the stability of a triangle, connecting the door frame and other components using screws and other tools to enhance stability. Door and window profiles typically use aluminum corner brackets at the joints between frames and sashes, and the angled design of the frames and sashes facilitates a snug fit. However, this results in pressure being applied to the corner brackets between frames and sashes, potentially leading to excessive stress on them. Therefore, we propose a new type of corner bracket for doors and windows. Utility Model Content

[0003] In view of the problems in the prior art, this utility model provides a corner fitting for doors and windows.

[0004] The technical solution adopted by this utility model to solve its technical problem is a corner assembly for doors and windows, including an inner window body. The outer periphery of the inner window body is equipped with horizontal and vertical frames for support by bolts, and there are two sets of both horizontal and vertical frames. The outer two end surfaces of the horizontal frame are integrally constructed with corner blocks for auxiliary support, and there are two sets of corner blocks. The outer two end surfaces of the vertical frame are provided with corner grooves that fit with the corner blocks, and there are two sets of corner grooves.

[0005] The inner circumference of the horizontal frame is integrally constructed with a locking strip, and there are multiple sets of locking strips. An interlocking corner body that fits the locking strip is inserted into the horizontal frame, and the end of the interlocking corner body away from the horizontal frame is inserted into the vertical frame. The inner circumference surface of the vertical frame is integrally constructed with a T-shaped strip, and the outer wall surface of the interlocking corner body is provided with a T-shaped groove that engages with the T-shaped strip.

[0006] By adopting the above technical solution, when using doors and windows, the glass can be directly installed on the inner window body, and the horizontal and vertical frames installed on the outer periphery of the inner window body form a frame structure that can be easily supported. At the same time, the multiple sets of corner blocks and corner grooves between the horizontal and vertical frames can fit together, so that the horizontal and vertical frames can be directly interlocked with each other, which can improve the stability after the horizontal and vertical frames are connected, and can share the pressure borne by the corner brackets, so that the doors and windows can operate more stably.

[0007] When splicing the vertical and horizontal frames, the corner pieces can be inserted into both ends of the horizontal frame first. The multiple sets of locking strips inside the horizontal frame can easily engage with the grooves on the outer periphery of the corner pieces, improving the stability of the connection between the corner pieces and the horizontal frame. Then, the vertical frame can be removed, allowing one end of the vertical frame to be inserted into the end of the corner piece furthest from the horizontal frame. At the same time, the T-shaped grooves on the outer periphery of the corner pieces can engage with the T-shaped strips on the inner periphery of the vertical frame, further improving the stability of the connection between the corner pieces and the vertical frame. During the insertion process of the corner pieces and the vertical frame, the corner grooves on the vertical frame will correspond to the corner pieces on the horizontal frame and can fit together later, allowing the vertical frame, horizontal frame, and corner pieces to be stably spliced ​​together on the outer periphery of the inner window. After the splicing is completed, screws or bolts can be used to fix it in the corresponding positions to complete the assembly of the door and window. The operation is simple and convenient.

[0008] Specifically, the inner circumferential surface of the corner groove is integrally constructed with a corner strip, and the side of the corner block near the corner groove and the outer circumferential surface of the corner block are both provided with sliding grooves that fit the corner strip.

[0009] By adopting the above technical solution, the corner strip in the corner groove can easily fit into the sliding groove on the outside of the corner block, which can improve the stability of the corner block and the corner groove after they are connected, thus enabling the vertical frame and the horizontal frame to be connected more stably.

[0010] Specifically, the outer wall surface of the vertical frame is integrally constructed with ear blocks that fit with the horizontal frame, and there are two sets of ear blocks.

[0011] By adopting the above technical solution, when the vertical frame and the horizontal frame are connected to each other through the corner assembly, the lugs on the vertical frame can fit into the grooves pre-set on the surface of the horizontal frame, which facilitates the auxiliary support of the right angle formed by the vertical frame and the horizontal frame and improves the stability of the connection between the two.

[0012] Specifically, the outer peripheral surface of the corner body is provided with grooves that fit both the vertical and horizontal frames, and there are multiple sets of grooves.

[0013] By adopting the above technical solution, the grooves on the outer periphery of the corner assembly body match the pre-set protrusions in the horizontal and vertical frames, which facilitates positioning during the installation of the corner assembly body and also improves the stability of the corner assembly body after it is connected to the vertical and horizontal frames.

[0014] Specifically, the inner circumferential surface of the horizontal frame is integrally constructed with trapezoidal strips that fit the corner body, and there are multiple sets of trapezoidal strips. The outer circumferential side surfaces of the corner body are integrally constructed with arc-shaped strips, and the inner circumferential surface of the vertical frame is provided with arc-shaped grooves that fit the arc-shaped strips, and there are two sets of arc-shaped grooves.

[0015] By adopting the above technical solution, the trapezoidal strip on the inner periphery of the horizontal frame and the groove on the outer periphery of the corner assembly body fit together, which facilitates auxiliary limiting support after the corner assembly body is connected to the horizontal frame. The arc-shaped strip on the outer periphery of the corner assembly body can fit together with the arc-shaped groove on the inner periphery of the vertical frame, which helps to improve the stability after the corner assembly body and the vertical frame are connected, so that the corner assembly body can stably support the vertical frame and the horizontal frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of vertical frames, horizontal frames, corner blocks and corner grooves, allows for the direct installation of glass on the inner window body when using doors and windows. The horizontal and vertical frames installed on the outer periphery of the inner window body form a frame structure that facilitates support. At the same time, the multiple sets of corner blocks and corner grooves between the horizontal and vertical frames can fit together, allowing the horizontal and vertical frames to be directly interlocked, which improves the stability of the connection between the horizontal and vertical frames and can share the pressure borne by the corner brackets, enabling the doors and windows to operate more stably.

[0018] 2. The technical solution of this application, through the design of corner assemblies, T-slots, locking strips, and T-shaped strips, allows for the initial insertion of corner assemblies into both ends of the horizontal frame during the splicing of the vertical and horizontal frames. Multiple locking strips inside the horizontal frame facilitate engagement with the grooves on the outer periphery of the corner assemblies, improving the stability of the connection between the corner assemblies and the horizontal frame. Then, the vertical frame can be removed, allowing one end of the vertical frame to be inserted into the end of the corner assemblies furthest from the horizontal frame. Simultaneously, the T-slots on the outer periphery of the corner assemblies engage with the T-shaped strips on the inner periphery of the vertical frame, further enhancing stability. During the insertion process, the corner slots on the vertical frame correspond to the corner blocks on the horizontal frame, subsequently fitting together. This ensures a stable splicing of the vertical and horizontal frames and the corner assemblies onto the outer periphery of the inner window. After splicing, screws or bolts are used to fix the assembly at the appropriate positions, completing the assembly of the door and window. The operation is simple and convenient.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a corner bracket for doors and windows, including an inner window body 1. The outer periphery of the inner window body 1 is bolted with a horizontal frame 2 and a vertical frame 3 for support, and there are two sets of both the horizontal frame 2 and the vertical frame 3. The outer two end surfaces of the horizontal frame 2 are integrally constructed with corner blocks 4 for auxiliary support, and there are two sets of corner blocks 4. The outer two end surfaces of the vertical frame 3 are provided with corner grooves 5 that fit with the corner blocks 4, and there are two sets of corner grooves 5. The inner periphery of the horizontal frame 2 is integrally constructed with a retaining strip 8, and there are multiple sets of retaining strips 8. An corner bracket 6 that fits with the retaining strip 8 is inserted into the horizontal frame 2, and the end of the corner bracket 6 away from the horizontal frame 2 is inserted into the vertical frame 3. The inner periphery of the vertical frame 3 is integrally constructed with a T-shaped strip 9, and the outer wall surface of the corner bracket 6 is provided with a T-shaped groove 7 that engages with the T-shaped strip 9.

[0027] When in use, the inner window 1 allows for direct installation of glass, while the horizontal frame 2 and vertical frame 3 installed on the outer periphery of the inner window 1 form a frame structure that provides support. At the same time, the multiple sets of corner blocks 4 and corner grooves 5 between the horizontal frame 2 and vertical frame 3 can fit together, allowing the horizontal frame 2 and vertical frame 3 to be directly interlocked, which improves the stability of the connection between the horizontal frame 2 and vertical frame 3 and can share the pressure borne by the corner brackets, making the doors and windows operate more stably.

[0028] When the vertical frame 3 and the horizontal frame 2 are spliced ​​together, the corner assembly 6 can be inserted into both ends of the horizontal frame 2 first. The multiple sets of locking strips 8 inside the horizontal frame 2 can easily engage with the grooves on the outer periphery of the corner assembly 6, which improves the stability of the connection between the corner assembly 6 and the horizontal frame 2. Then, the vertical frame 3 can be removed so that one end of the vertical frame 3 can be inserted into the end of the corner assembly 6 away from the horizontal frame 2. At the same time, the T-shaped groove 7 on the outer periphery of the corner assembly 6 can engage with the T-shaped strip 9 on the inner periphery of the vertical frame 3, which improves the stability of the connection between the corner assembly 6 and the vertical frame 3. During the process of inserting the corner assembly 6 and the vertical frame 3, the corner groove 5 on the vertical frame 3 will correspond to the corner block 4 on the horizontal frame 2 and can fit together in the future. This allows the vertical frame 3, the horizontal frame 2 and the corner assembly 6 to be stably spliced ​​together on the outer periphery of the inner window 1. After the splicing is completed, the door and window can be assembled by fixing it in the corresponding positions with screws or bolts. The operation is simple and convenient.

[0029] like Figure 3 and Figure 4 As shown, the inner circumferential surface of the corner groove 5 is integrally constructed with a corner strip 11, and the side of the corner block 4 near the corner groove 5 and the outer circumferential surface of the corner body 6 are both provided with a sliding groove 12 that fits with the corner strip 11.

[0030] In use, the corner strip 11 in the corner groove 5 can easily fit into the sliding groove 12 on the outside of the corner block 4, which can improve the stability of the corner block 4 and the corner groove 5 after they are connected, so that the vertical frame 3 and the horizontal frame 2 can be connected more stably.

[0031] like Figure 2 and Figure 3 As shown, the outer wall surface of the vertical frame 3 is integrally constructed with ear blocks 13 that fit with the horizontal frame 2, and there are two sets of ear blocks 13.

[0032] When in use, when the vertical frame 3 and the horizontal frame 2 are connected to each other through the corner assembly 6, the ear block 13 on the vertical frame 3 can fit into the groove preset on the surface of the horizontal frame 2, which facilitates the auxiliary support of the right angle formed by the vertical frame 3 and the horizontal frame 2 and improves the stability of the connection between the two.

[0033] like Figure 3 and Figure 4 As shown, the outer peripheral surface of the corner body 6 is provided with grooves 10 that fit both the vertical frame 3 and the horizontal frame 2, and there are multiple sets of grooves 10.

[0034] When in use, the groove 10 on the outer periphery of the corner assembly 6 matches the pre-set protrusions in the horizontal frame 2 and the vertical frame 3, which facilitates positioning when the corner assembly 6 is installed, and also improves the stability of the corner assembly 6 after it is connected to the vertical frame 3 and the horizontal frame 2.

[0035] like Figure 3 and Figure 4As shown, the inner circumferential surface of the horizontal frame 2 is integrally constructed with trapezoidal strips 16 that fit with the corner body 6, and there are multiple sets of trapezoidal strips 16. The outer circumferential side surfaces of the corner body 6 are integrally constructed with arc-shaped strips 15, and the inner circumferential surface of the vertical frame 3 is provided with arc-shaped grooves 14 that fit with the arc-shaped strips 15, and there are two sets of arc-shaped grooves 14.

[0036] In use, the trapezoidal strip 16 on the inner periphery of the horizontal frame 2 fits into the groove on the outer periphery of the corner assembly 6, which facilitates auxiliary limiting support after the corner assembly 6 is connected to the horizontal frame 2. The arc-shaped strip 15 on the outer periphery of the corner assembly 6 can fit into the arc-shaped groove 14 on the inner periphery of the vertical frame 3, which helps to improve the stability after the corner assembly 6 and the vertical frame 3 are connected, so that the corner assembly 6 can stably support the vertical frame 3 and the horizontal frame 2.

[0037] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. When using the door / window, the inner window body 1 allows for direct glass installation. The horizontal frame 2 and vertical frame 3 installed on the outer periphery of the inner window body 1 form a frame structure for easy support. Simultaneously, the multiple sets of corner blocks 4 and corner grooves 5 between the horizontal frame 2 and vertical frame 3 can fit together, allowing the horizontal frame 2 and vertical frame 3 to directly interlock, improving the stability of the connection between the horizontal frame 2 and vertical frame 3 and distributing the pressure borne by the corner brackets, thus enabling more stable operation of the door / window. Furthermore, when splicing the vertical frame 3 and horizontal frame 2, the corner brackets 6 can be inserted into both ends of the horizontal frame 2, and the multiple sets of locking strips 8 inside the horizontal frame 2 facilitate the connection with the outer corner brackets 6. The grooves on the periphery interlock to improve the stability of the connection between the corner assembly 6 and the horizontal frame 2. Then, the vertical frame 3 can be removed so that one end of the vertical frame 3 can be inserted into the end of the corner assembly 6 away from the horizontal frame 2. At the same time, the T-shaped groove 7 on the outer periphery of the corner assembly 6 can interlock with the T-shaped strip 9 on the inner periphery of the vertical frame 3 to improve the stability of the connection between the corner assembly 6 and the vertical frame 3. During the insertion process of the corner assembly 6 and the vertical frame 3, the corner groove 5 on the vertical frame 3 will correspond to the corner block 4 on the horizontal frame 2 and can fit together in the future. This allows the vertical frame 3, the horizontal frame 2 and the corner assembly 6 to be stably spliced ​​together on the outer periphery of the inner window 1. After the splicing is completed, the door and window can be assembled by fixing it in the corresponding positions with screws or bolts. The operation is simple and convenient.
