Description

Technical Field

[0001] This utility model relates to the technical field of door and window corner fittings, specifically to a door and window corner fitting. Background Technology

[0002] Aluminum alloy doors and windows include single-layer and double-layer models. A single-layer aluminum alloy door or window frame is composed of four single frame profiles joined at the corners, while a double-layer aluminum alloy door or window frame is composed of four double frame strips joined at the corners. Each double frame strip is formed by two single frame profiles joined side-by-side, connected by thermally insulated connectors. Double-layer aluminum alloy doors and windows are further divided into equal-frame and unequal-frame models. In equal-frame double-layer aluminum alloy doors and windows, both layers have equal height and width. Unequal-frame double-layer aluminum alloy doors and windows have two layers of aluminum alloy doors and windows with unequal heights and widths. The double sash frame strips are made by splicing a large sash frame profile and a small sash frame profile side by side. In the existing technology, most of them are produced by cutting the sash frames at 45 degrees. That is, the two ends of the four sash frame profiles are cut at 45 degrees, and the four sash frame profiles are connected to form a rectangle by integral corner brackets. Then, hexagonal screws are used to fix the profiles to the integral corner brackets. After fixing, glue is filled to complete the assembly. However, depending on the different assembled profiles, there may be gaps between the inner wall of the profile and the corner bracket after docking with the integral corner bracket. Then, a large amount of glue needs to be injected to fill the gaps and adhere and fix the inner walls of the profiles at both ends to the two ends of the corner brackets. It is also possible that after glue is injected, only one side of the corner bracket is bonded to the inner wall of the profile through glue, which affects the structural stability after assembly, increases the cost of glue injection, and the fixation with hexagonal screws is relatively cumbersome and inconvenient, requiring personnel to tighten them one by one. Utility Model Content

[0003] The purpose of this utility model is to provide a door and window corner fitting to solve the problems mentioned in the background art.

[0019] Example:

[0020] Please see Figures 1-3 This utility model provides a technical solution:

[0021] A door and window corner fitting includes an integral corner bracket 1, which comprises an upper corner bracket 2 and a lower corner bracket 3. An extension positioning mechanism is installed on the upper corner bracket 2 and the lower corner bracket 3. The extension positioning mechanism includes two sets of extension springs 4. A connecting groove 5 is formed at the central fitting area inside the upper corner bracket 2 and the lower corner bracket 3. Both sets of extension springs 4 are installed on the inner wall of the connecting groove 5. Positioning holes 6 are formed at both ends of the integral corner bracket 1. A first inclined surface 7 is formed around the outer periphery of the positioning holes 6 on the outside of the integral corner bracket 1. The positioning holes 6 at both ends are interconnected. A mating groove 8 is formed on both inner walls of the positioning holes 6. Both ends of the integral corner bracket 1 are fitted with... A profile 9 is attached, with a placement groove 10 on one side. The side wall of the placement groove 10 has mounting holes corresponding to the positioning holes 6. A positioning plate 11 is engaged inside the placement groove 10. A positioning cylinder 12 is engaged on the positioning plate 11 via an installation mechanism. Both ends of one side of the positioning cylinder 12 are fitted with mating plates 13, the diameter of which is larger than the diameter of the mating plate 13. One end of the mating plate 13 has a second inclined surface 14 that fits against the first inclined surface 7. Movable grooves 19 are provided at both the front and rear ends of the top of the lower corner bracket 3. Movable partitions 20 are slidably connected inside the movable grooves 19. During use, this device can... After attaching the two end profiles 9 to the integral corner bracket 1, insert the two sets of positioning plates 11 into the inner side of the placement groove 10, so that the positioning cylinder 12 passes through the mounting hole and approaches the positioning hole 6. The second inclined surface 14 on one side of the mating plate 13 abuts against the first inclined surface 7. When pushed forward, the upper corner bracket 2 and the lower corner bracket 3 gradually separate, the extension spring 4 is stretched, and the movable partition 20 unfolds from the inner side of the movable groove 19. After the two end mating plates 13 move to the mating groove 8, they are inserted into it. The upper corner bracket 2 and the lower corner bracket 3 retract again. The longer the length of the mating plate 13, the farther the distance between the inner walls of the two ends of the positioning hole 6, so that the integral corner bracket 1 unfolds and the profiles 1 are aligned. The inner wall of the material 9 is fitted together. During the specific operation, the operator can change the corresponding positioning plate 11 according to the gap during docking so that the length of the docking plate 13 on the positioning cylinder 12 is sufficient to allow the overall corner bracket 1 to fit with the inner wall of the profile 9. The slope of the second inclined surface 14 of the docking plate 13 of different lengths can be increased accordingly, so that the first inclined surface 7 can be continuously fitted. The structure is simple and easy to operate. During installation, it is only necessary to press inward to complete the fixation. The appropriate docking plate 13 can also be selected according to the actual gap size to cooperate with the extension positioning mechanism to expand the overall corner bracket 1, which enhances the stability of the structure and reduces the cost of glue injection.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the overall corner bracket 1 has two sets of first filling grooves 15 at both ends of its top, and second filling grooves 16 above the positioning holes 6 at both ends of the overall corner bracket 1. A third filling groove 17 is provided at the center of both ends of the overall corner bracket 1. Multiple sets of spacers 18 are arranged and installed on both sides of the upper corner bracket 2 and the lower corner bracket 3. First connecting holes 21 are provided inside the adjacent spacers 18 on both sides of the second filling groove 16. Second connecting holes 2 are conveniently provided on the side walls at both ends of the first filling groove 15, communicating with the inner sides of the second filling groove 16 and the third filling groove 17. 2. The bottom inner side of the first filling groove 15 is provided with a third connecting hole 23 extending to the inner side of the positioning hole 6. By injecting the adhesive into the positioning hole 6 from the positioning cylinder 12 on one side, the adhesive is poured into the first filling groove 15, the second filling groove 16 and the third filling groove 17 and the area between adjacent spacers 18 through the unfolded gap, the first connecting hole 21, the second connecting hole 22 and the third connecting hole 23, and is bonded and fixed to the inner wall of the profile 9. The movable partition 20 can isolate the connecting groove 5 and part of the empty area to prevent the adhesive from being poured into it.

[0023] The implementation principle of a door and window corner fitting according to an embodiment of this application is as follows: When using this device, the two end profiles 9 are sleeved onto the overall corner bracket 1, and then the two sets of positioning plates 11 are inserted into the placement groove 10. This allows the positioning cylinder 12 to pass through the mounting hole and approach the positioning hole 6. The second inclined surface 14 on one side of the mating plate 13 abuts against the first inclined surface 7. When pushed forward, the upper corner bracket 2 and the lower corner bracket 3 gradually separate, the extension spring 4 is stretched, and the movable partition 20 unfolds from the inside of the movable groove 19. After the two end mating plates 13 move to the mating groove 8, they are inserted therein. The upper corner bracket 2 and the lower corner bracket 3 retract again. The longer the length of the mating plate 13, the farther the distance between the inner walls of the two ends of the positioning hole 6, allowing the overall corner bracket 1 to unfold and fit against the inner wall of the profile 9. In specific operation, the operator can replace the corresponding positioning plate 11 according to the gap during mating to adjust the length of the mating plate 13 on the positioning cylinder 12. The overall corner bracket 1 is sufficiently fitted to the inner wall of the profile 9. The slope of the second inclined surface 14 of the butt plate 13 of different lengths can be increased accordingly, allowing the first inclined surface 7 to be continuously fitted. The structure is simple and easy to operate. During installation, it is only necessary to press inward to complete the fixation. The appropriate butt plate 13 can also be selected according to the actual gap size to cooperate with the extension positioning mechanism to expand the overall corner bracket 1, which enhances the stability of the structure and reduces the cost of glue injection. By injecting the glue into the positioning hole 6 from the positioning cylinder 12 on one side, the glue is poured into the first filling groove 15, the second filling groove 16, and the third filling groove 17 and the area between adjacent spacers 18 through the expanded gap, the first connecting hole 21, the second connecting hole 22, and the third connecting hole 23, and is bonded and fixed to the inner wall of the profile 9. The movable partition 20 can isolate the connecting groove 5 and part of the empty area to prevent the glue from being poured into them.
