Technical Field

[0001] The utility model relates to the technical field of building doors and windows, in particular to a quickly detachable hidden inwards-opening and downward-swinging system. Background Art

[0002] With the improvement of living standards, people gradually prefer windows with a large view, resulting in the existing window sashes being large and heavy. The opening and closing of the casement window is realized through the cooperation of various hardware parts. Since the hardware parts are an integral non-detachable whole, it is necessary to install the hardware parts on the window sash and then lift the window sash to install it on the frame, which is time-consuming and laborious and inconvenient for installation. At the same time, the existing door and window profiles are mainly European standard C-grooves and European standard U-grooves. Due to the different groove openings of the two, the specifications of the hardware parts are limited, and it is impossible to mix the C-groove and U-groove profiles, which is troublesome to use and has a high cost.

[0003] Based on this, the utility model designs a quickly detachable hidden inwards-opening and downward-swinging system to solve the above problems. Content of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model.

[0027] The attached drawings are specific embodiments of the present utility model, such as Figures 1-9As shown in the figure, the utility model relates to a quickly detachable hidden inward-opening and downward-swinging system, which comprises an upper connecting component and a lower connecting component. The lower connecting component includes a lower frame component 15 and a lower sash component 14. The lower frame component 15 includes a bottom plate 2, a plate A 3, and a plate B 9. The lower sash component 14 includes a sash plate 6, a connecting piece A 7, and a connecting piece B 8. The bottom end of the bottom plate 2 is fixed to a C-shaped groove profile by components such as a clamping plate 10. An internal hexagonal screw 1 is placed in the bottom plate hole 2.1. The rivet column of the internal hexagonal screw 1 has threads, and there is a threaded hole in the middle of the clamping plate 10. The clamping plate 10 is screwed onto the internal hexagonal screw 1. By turning the internal hexagonal screw 1 with a wrench, the clamping plate 10 is stuck on the C-shaped groove. Continuing to turn the wrench, using the thread principle, the internal hexagonal screw 1 will drive the clamping plate 10 to move upward. After the clamping plate 10 clamps the profile, the installation is completed. This structure is not limited by the thickness of the profile and is more firmly installed than the conventional rotating vane by 90 degrees. The side of the bottom plate 2 is riveted and fixed with a fixing piece 11 by a through-hole hexagonal rivet 12, which can be stuck on the profile surface for fixation, and installation screws can be driven according to the selection. One end of the plate A 3 is riveted with an adjusting screw 5, and the adjusting screw 5 is stuck in the sash plate groove 6.1 to achieve sealing adjustment. One end of the plate B 9 is riveted with a support column 13 passing through the end of the sash plate 6, and a screw 4 is installed above. By adjusting the screw 4, the up and down adjustment of the window sash can be achieved. The lower frame component 15 and the lower sash component 14 adopt a detachable structure. By turning the adjusting screw 5 to the notch 6.2 of the sash plate groove, the lower sash component 14 can be detached from the lower frame component 15, which is convenient for the installation of the window sash. Both ends of the sash plate 6 are respectively fixed to the connecting piece A 7 and the connecting piece B 8. There are screw mounting holes on both the connecting piece A and the connecting piece B, and they are connected as a whole and installed on the window sash. Therefore, the end face of the sash plate 6 is designed with a U-shaped structure, which can be adapted to the U-shaped groove profile of the sash member 29. When installing the window sash, the lower frame component 15 and the lower sash component 14 are respectively installed on the frame member 30 and the sash member 29 of the window, and then the lower sash component 14 is hung on the lower frame component 15 to complete the installation of the lower connecting component.

[0028] The upper connecting part includes an upper frame part 27 and an upper fan part 28. The upper frame part 27 includes a hinge assembly 17, a fixed plate 16, a connecting plate 20, an adjustment block 19, and a locking wrench 22. The upper fan part 28 includes a fixed plate 24, a slide plate 26, and a short plate 25. The hinge assembly 17 is connected to the fixed plate 16 by rivets. Its structure is the same as that of the bottom plate 2 in the lower connecting part, and a card plate is used to clamp the C-notch profile. The adjustment block 19 passes through the fixed plate 16 and is connected to the connecting plate 20. The adjustment screw 18 is horizontally stuck in the groove of the fixed plate 16. The adjustment block 19 and the adjustment screw 18 are both threaded. Turn the adjustment screw 18 The connecting plate 20 is moved left and right using the principle of threading to adjust the window sash. A rivet stud 21 is connected to the middle of the connecting plate 20, and a locking pin 23 is designed at the end of the connecting plate 20. The locking pin 23 has a similar profile to the elliptical notch 24.1. The locking pin 23 passes through the connecting plate 20 and is riveted to the locking wrench 22. The locking wrench 22 has a hexagonal hole 22.1. The fixing plate 24 has an elliptical notch 24.1. A short plate 25 is connected to the middle of the fixing plate 24. The locking pin 23 can be stuck in the elliptical notch 24.1 and slides. The rivet stud 21 passes through the short plate 25 to connect the upper frame member 27 and the upper sash member 28 into one. A locking pin 31 is connected to the sliding plate 26, which slides in the notch of the fixing plate 24. The locking pin 31 is designed to be eccentric to adjust the sealing of the window sash.

[0029] refer to Figures 5-9 When installing the window sash, fix the upper frame member 27 and the upper fan member 28 to the window frame member 30 and the fan member 29 respectively, and then hang the upper fan member 28 on the upper frame member 27 through the rivet column 21. After alignment, turn the locking wrench 22 clockwise or counterclockwise 90 degrees. At this time, the locking nail 23 is stuck in the elliptical notch 24.1, and the upper connecting member is installed; when disassembling, use a tool to rotate the hexagonal hole 22.1, thereby turning the locking wrench 22 clockwise or counterclockwise 90 degrees, refer to Figures 8-9 At this time, the locking nail 23 can just fall off from the oval notch 24.1, and the rivet column 21 can fall off from the short plate 25, realizing the rapid disassembly of the upper frame component 27 and the upper fan component 28.
