Description

Technical Field

[0001] The present application relates to the technical field of door and window hinges, and in particular to an invisible power-assisted hinge for doors and windows. Background Art

[0002] Assisted hinges for doors and windows, also known as damping hinges or buffer hinges, are a special type of hardware for doors and windows. Their main function is to provide a smooth, slow and quiet closing effect when closing doors and windows, preventing them from directly hitting the frame and causing noise or damage. This type of hinge is becoming more and more popular in modern homes and offices because it not only improves the user experience, but also protects doors and windows and frames, extending their service life.

[0003] In the prior art, a power-assisted hinge is usually composed of two fixing parts, which are rotatably connected to each other, one fixing part is fixedly connected to the door frame and the other is fixedly connected to the window frame. However, the hinge is usually on the outside of the door frame and the window frame, which looks unsightly as a whole. Therefore, the present application provides an invisible power-assisted hinge for doors and windows. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide an invisible power-assisted hinge for doors and windows to solve the problem that the power-assisted hinge is on the outside of the door frame and window frame, which makes the overall appearance unsightly.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an invisible power-assisted hinge for doors and windows, arranged between the window frame and the window, comprising a first power-assisted hinge and a pair of second power-assisted hinges, an upper hinge pressure plate fixedly installed on the first power-assisted hinge, the upper hinge pressure plate fixedly connected to the window frame by bolts, the first power-assisted hinge is rotatably connected to a first pin shaft away from the upper hinge pressure plate, the first pin shaft is also rotatably connected to a first connecting piece, the first connecting piece is connected to a second pin shaft at one end away from the first power-assisted hinge, the second pin shaft is also rotatably connected to a second connecting piece, the second connecting piece is connected to a third pin shaft at one end away from the first connecting piece, the third pin shaft is also rotatably connected to the second power-assisted hinge, lower hinge pressure plates are fixedly connected to both ends of the second power-assisted hinge, and the lower hinge pressure plates are fixedly connected to the window by bolts.

[0006] By adopting the above technical solution, when the window frame is opened, the window frame is pushed, and the hinge structure is opened, and the window frame drives the second power-assisted hinge. Because the first power-assisted hinge and the second power-assisted hinge are abutted against each other when not opened, the second power-assisted hinge first drives the first connecting piece to rotate. When the window frame rotates to a certain angle, it drives the second connecting piece to rotate, so that the window frame is fully opened. In this application, by designing the power-assisted hinge device to be foldable, after it is installed between the door and the window, the hinge structure is not easy to see in the closed state, thereby increasing the sense of unity and improving its aesthetics. At the same time, the power-assisted hinge is designed to be four pages, and when different hinge structures are assisted, the range of extension can be widened, so that different types of hinge mechanisms can be assisted.

[0007] The cam is provided with a sliding groove, the sliding groove is slidably connected to the support, and the sliding groove is connected to the support through the sliding groove, and the support arm is fixedly connected to the window frame.

[0008] By adopting the above technical solution, when the window frame rotates, the support arm rotates along with it, and at the same time drives the support piece on the support arm. The sliding column at the other end of the support piece slides in the slide groove first, and the support piece drives the guide piece to be pulled along with the rotation of the rotating column to complete the opening of the window frame. By connecting one end of the support piece in the slide groove, it can be easier to open the window frame when pushing it. Through the different axes in the hinge structure, while opening it, the power-assisted hinges have multiple axes. When assisting it, it can be ensured that the window frame will not be stuck when opening.

[0009] Furthermore, a damping gasket is rotatably arranged at the rotatable connection between the support arm and the guide vane.

[0010] By adopting the above technical solution, additional supporting force is provided for the window frame after it is opened.

[0011] Furthermore, a copper sheet is sleeved on the outer side of the sliding column.

[0012] By adopting the above technical solution, the copper sheet has good ductility, so it can be smoother when sliding the sliding column, and its service life can be improved.

[0013] Furthermore, a slot is provided on the supporting piece near the pivot adjustment end.

[0014] By adopting the above technical solution, when the window frame is rotated to the maximum limit, the slot on the supporting sheet will clamp the window frame, thereby preventing the rotation angle from being too large.

[0015] Furthermore, the pivot is also provided with a steel ball in the setting of the support arm sleeve.

[0016] By adopting the above technical solution, the setting of the steel column can make the rotation of the pivot more natural.

[0017] Furthermore, flange gaskets are installed at the connection points between the first power-assisting hinge and the first connecting piece, the first connecting piece and the second connecting piece, and the second connecting piece and the second power-assisting hinge.

[0018] By adopting the above technical solution, it is ensured that the friction during connection can be reduced.

[0019] Furthermore, the flange gasket is made of rubber material.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By designing the power hinge device to be foldable, the hinge structure is not easy to be seen when the doors and windows are closed, which greatly increases the beauty and sense of unity of the overall doors and windows. This design makes the doors and windows look more simple and generous, and is more in line with the modern home decoration style.

[0022] 2. During the opening process of doors and windows, the hinge structure follows a multi-axis, non-concentric movement path as the doors and windows are opened, but it is located on both sides of the doors and windows, and its supporting strength is insufficient. It is necessary to add a power-assisted hinge in the middle to provide support force, but the hinges in the prior art are all single-axis rotating, which is different from the movement path of the hinge structure. The hinges in the prior art will get stuck when used in conjunction with the hinge structure. The present application sets the power-assisted hinge to a four-leaf hinge, which is also multi-axis, forming a rotating joint that can rotate with the hinge. Therefore, they can cooperate with each other to prevent the window frame from getting stuck when it is opened, thereby improving the user experience.

[0023] 3. The design of the card slot on the support plate can effectively prevent the window frame from rotating too much, thereby avoiding damage or safety hazards caused by excessive opening. This design increases the safety of doors and windows. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] Example, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8, an invisible power-assisted hinge for doors and windows, arranged between a window frame 1 and a window 2, comprising a first power-assisted hinge 31 and a pair of second power-assisted hinges 32, an upper hinge pressure plate 33 is fixedly mounted on the first power-assisted hinge 31, the upper hinge pressure plate 33 is fixedly connected to the window frame 1 by bolts, the first power-assisted hinge 31 is rotatably connected to a first pin shaft 301 away from the upper hinge pressure plate 33, a first connecting piece 35 is also rotatably connected to the first pin shaft 301, an end of the first connecting piece 35 away from the first power-assisted hinge 31 is connected to a second pin shaft 302, a second connecting piece 36 is also rotatably connected to the second pin shaft 302, an end of the second connecting piece 36 away from the first connecting piece 35 is connected to a third pin shaft 303, the third pin shaft 303 is also rotatably connected to the second power-assisted hinge 32, lower hinge pressure plates 34 are fixedly connected to the second power-assisted hinge 32 at both ends, the lower hinge pressure plates 34 are fixedly connected to the window 2 by bolts, the hinge structure comprises a support 4 and a bracket arm 41, a gusset plate 42 is fixedly connected to the bottom of the support 4, and the gusset plate 42 is fixedly connected to the window frame 1. A vertical plate 43 extends upward from one end of the support 4, and a through hole is opened in the vertical plate 43, and a flat plate 44 extends from the through hole. A rotating column 45 is rotatably arranged on the flat plate 44, and the bottom end of the rotating column 45 is rotatably connected to a supporting piece 47, and the end of the supporting piece 47 away from the rotating column 45 is rotatably connected to a guide piece 48, and the end of the guide piece 48 away from the supporting piece 47 is rotatably connected The support arm 41 is connected to a support sheet 47, and a rotating column 45 is fixedly arranged on the support sheet 47. One end of the support arm 41 is also sleeved on a pivot 46. The bottom end of the pivot 46 is rotatably connected to a support sheet 5. The end of the support sheet 5 close to the rotating column 45 is rotatably connected to the support sheet 47. The end of the support sheet 5 away from the pivot 46 is rotatably arranged with a sliding column 51. A sliding groove 52 is provided on the support 4. The sliding column 51 is slidably connected to the support 4 through the sliding groove 52. The support arm 41 is fixedly connected to the window 2.

[0035] When the window 2 rotates, the support arm 41 rotates along with it, and at the same time drives the supporting piece 5 on the support arm 41, and the sliding column 51 at the other end of the supporting piece 5 first slides in the sliding groove 52, and the supporting piece 47 drives the pulling guide piece 48 along with the rotation of the rotating column 45 to complete the opening of the window 2. With one end of the supporting piece 5 connected to the sliding groove 52, it can be easier to open when pushing the window 2. At the same time, the window 2 drives the second power-assisting hinge 32. Since the first power-assisting hinge 31 and the second power-assisting hinge 32 are against each other when not opened, the second power-assisting hinge 32 drives the first connecting piece 35 to rotate. When the window 2 rotates to a certain angle, it will drive the second connecting piece 36 to rotate, allowing the window 2 to be fully opened. By designing the power-assisted hinge device 3 to be foldable, after it is installed between the door and the window, the hinge structure is not easy to see in the closed state, thereby increasing the sense of unity and improving its aesthetics. At the same time, in the process of opening the doors and windows, the hinge structure and the power-assisted hinge are used in coordination. Since the hinge structure has multiple axes that are not concentric, the opening of the doors and windows is smoother. At the same time, the power-assisted hinge is a four-leaf hinge with multiple axes, so they can cooperate with each other to prevent the window frame from getting stuck when it is opened.

[0036] In this embodiment, a damping gasket 6 is rotatably provided at the rotatable connection between the support arm 41 and the guide piece 48 to provide additional supporting force after the window 2 is opened.

[0037] In this embodiment, a copper sheet 61 is sleeved on the outer side of the sliding column 51. The copper sheet 61 has good ductility, so the sliding column 51 can be slid more smoothly and its service life can be increased.

[0038] In this embodiment, a slot 62 is provided on the support sheet 47 near the pivot 46. When the window 2 is rotated to the maximum, the slot 62 on the support sheet 47 will hold the window 2, thereby preventing the window from rotating too much.

[0039] In this embodiment, a steel ball 63 is also installed in the setting of the pivot 46 in the support arm 41 set of equipment. The setting of the steel column can make the rotation of the pivot 46 more natural.

[0040] In this embodiment, flange gaskets 37 are installed at the connection points between the first power-assisting hinge 31 and the first connecting piece 35, the first connecting piece 35 and the second connecting piece 36, and the second connecting piece 36 and the second power-assisting hinge 32 to ensure that friction can be reduced during connection. The flange gaskets 37 are made of rubber material.

[0041] Specific implementation process:

[0042] During this process, you will first feel a slight resistance from the power-assisted hinges. This is because the damping mechanism in the power-assisted hinges starts to work, ensuring that the doors and windows open smoothly. As the doors and windows rotate, the hinge structure also starts to work. The support arm 41 rotates with the rotation of the doors and windows, and at the same time drives the support plate 5, so that the sliding column 51 slides in the slide groove 52 of the support 4. This design ensures that the doors and windows can move smoothly during the opening process, and also increases their stability. When the doors and windows rotate to a certain angle, the second connecting piece 36 starts to rotate, further assisting the full opening of the doors and windows. After the doors and windows are fully opened, the slot 62 on the support plate 47 may contact the doors and windows, which plays a role in preventing excessive opening. This helps to protect the doors and windows and hinges from damage and increases the safety of use.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
