Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a three-dimensional hidden hinge. Background Technology

[0002] 3D concealed hinges are a type of high-end hinge that combines concealed installation with multi-directional adjustment. They are mainly used in scenarios where aesthetics and door gap precision are critical (such as minimalist wooden doors, hidden doors, and high-end cabinets).

[0003] Traditional concealed hinges only support fine-tuning in one direction (such as up and down or left and right), which cannot meet the precise adjustment needs of the door leaf in three-dimensional space (up and down, left and right, front and back) at the same time. This results in repeated disassembly or shim compensation during installation, which is inefficient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a three-dimensional hidden hinge, which solves the problem that hidden hinges only support fine-tuning in a single direction (such as up and down or left and right), and cannot simultaneously meet the precise adjustment needs of the door leaf in three-dimensional space (up and down, left and right, front and back), resulting in repeated disassembly or shim compensation during installation and low efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a three-dimensional hidden hinge, including a first blade and a second blade, a second U-shaped hole is fixedly opened on the surface of the first blade, the first blade and the second blade are rotatably connected by a shaft, connecting blocks are fixedly installed on both sides of the second blade, and a threaded sleeve is threadedly sleeved on the surface of the connecting block, and an installation block is rotatably sleeved on the surface of the threaded sleeve. The second blade, the connecting block and the installation block are slidably sleeved with a shell, and the bottom of the shell is symmetrically opened with a first U-shaped hole.

[0006] Preferably, a bolt is movably fitted onto the surface of the connecting block, one end of the bolt penetrating the surface of the mounting block and extending into the first U-shaped hole, where a nut is installed.

[0007] Preferably, the surfaces of the outer casing and the first blade are provided with cover plates.

[0008] Preferably, the cover plate covers the second U-shaped hole and the bottom of the outer casing.

[0009] Preferably, a limit rod is fixedly connected to the bottom of the connecting block.

[0010] Preferably, the limiting rod is engaged in the inner cavity of the mounting block.

[0011] This invention provides a three-dimensional hidden hinge. Compared with the prior art, it has the following advantages:

[0012] This three-dimensional hidden hinge uses the first and second U-shaped holes to adjust the vertical and horizontal spacing of the door. Rotating the threaded sleeve causes the mounting block to move on the bolt, thereby adjusting the depth of the second blade within the outer shell cavity and adjusting the horizontal spacing of the door. This allows for spacing adjustment in different directions, making it easier to adjust for errors during installation. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-6This utility model provides a technical solution: a three-dimensional hidden hinge, including a first blade 3 and a second blade 5. A second U-shaped hole 31 is fixedly opened on the surface of the first blade 3. The first blade 3 and the second blade 5 are rotatably connected by a shaft core 2. Connecting blocks 6 are fixedly installed on both sides of the second blade 5, and a threaded sleeve rod 61 is threadedly sleeved on the surface of the connecting block 6. An installation block 7 is rotatably sleeved on the surface of the threaded sleeve rod 61. The second blade 5, the connecting block 6, and the installation block 7 are slidably sleeved on the outer shell 1. Then, a screw passes through the inner cavity of the second U-shaped hole 31. Since there is also a space for movement, the front and rear distance can be adjusted. Since the lower end of the threaded sleeve rod 61 is rotatably sleeved on the installation block 7, and the upper end is threadedly sleeved on the connecting block 6, rotating the threaded sleeve rod 61 causes the threaded sleeve rod 61 to drive the installation block 7 to move on the bolt 63, thereby adjusting the depth of the second blade 5 in the inner cavity of the outer shell 1.

[0022] The bottom of the outer shell 1 is symmetrically provided with a first U-shaped hole 11. A bolt 63 is movably fitted onto the surface of the connecting block 6. One end of the bolt 63 passes through the surface of the mounting block 7 and extends into the first U-shaped hole 11, where a nut is installed. One end of the bolt 63 extends out of the first U-shaped hole 11 and is tightened by the nut. One end of the bolt 63 has a movable space inside the first U-shaped hole 11, so the second blade 5 can be dragged to move up and down inside the outer shell 1. After the position is determined, it is connected to the bolt 63 by the nut to tighten it.

[0023] A cover plate 4 is provided on the surface of the outer shell 1 and the first blade 3. The cover plate 4 covers the second U-shaped hole 31 and the bottom of the outer shell 1. The cover plate 4 is used to cover the second U-shaped hole 31 and the bottom of the outer shell 1 to avoid exposure and improve aesthetics.

[0024] The first U-shaped hole 11 is vertically arranged, while the second U-shaped hole 31 is horizontally arranged.

[0025] A limiting rod 62 is fixedly connected to the bottom of the connecting block 6. The limiting rod 62 is snapped into the inner cavity of the mounting block 7. The limiting rod 62 is used for positioning and installing the mounting block 7.

[0026] During operation, the first blade 3 and the second blade 5 are first rotatably connected by the shaft core 2. Then, the mounting block 7 is sleeved on the lower end of the threaded sleeve rod 61 and inserted into the limiting rod 62, so that the mounting block 7 is installed below the connecting block 6. Then, the second blade 5, the connecting block 6 and the mounting block 7 are movably sleeved in the inner cavity of the outer shell 1.

[0027] Then, the bolt 63 is passed through the connecting block 6 and the mounting block 7 and extended into the first U-shaped hole 11. A nut is installed, and then the outer shell 1 is installed on the door leaf. At this time, the bolt 63 is not yet tightened. Therefore, the first U-shaped hole 11 provides a space for the second blade 5 to move up and down in the inner cavity of the outer shell 1 to adjust the vertical distance of the door. After the position is determined, the bolt 63 is rotated again so that the bolt 63 is automatically locked onto the outer shell 1 by the nut.

[0028] Then, the screw is passed through the second U-shaped hole 31. The front and rear distance of the door is adjusted through the movable space of the second U-shaped hole 31, and the first leaf 3 is installed on the door frame.

[0029] Finally, by rotating the threaded sleeve 61, since the lower end of the threaded sleeve 61 is rotated and sleeved on the mounting block 7, while the upper end is threaded and sleeved on the connecting block 6, rotating the threaded sleeve 61 causes the mounting block 7 to move on the bolt 63, thereby adjusting the depth of the second blade 5 in the inner cavity of the outer shell 1, which in turn adjusts the left and right spacing of the door.

[0030] Therefore, this hinge allows for adjustment of the spacing in different directions on the door, making it easy to adjust for errors during installation.
