[0064] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0065] Example 1

[0066] Please refer to Figures 1-5 A modular concealed hinge includes a first mounting base 1, a second mounting base 2, a swing arm mounting base connecting bolt 4, and a rotating swing arm 5. The first mounting base 1 and the second mounting base 2 are respectively mounted on two objects to be connected, with an embedded installation method, thus forming a concealed installation. The swing arm mounting base 3 is installed inside the first mounting base 1, and the swing arm mounting base connecting bolt 4 passes through the swing arm mounting base 3 and is threadedly connected to the first mounting base 1. The swing arm mounting base connecting bolt 4 can adjust the installation height of the swing arm mounting base 3 inside the first mounting base 1 to adapt to different installation requirements. The two ends of the rotating swing arm 5 are hinged to the second mounting base 2 and the swing arm mounting base 3 respectively, allowing the first mounting base 1 and the second mounting base 2 to rotate around the rotating swing arm 5 as an axis, thereby realizing the hinge function. The first mounting base 1, the second mounting base 2, the swing arm mounting base 3, and the rotating swing arm 5 can all be freely combined and installed. The combination order can be adjusted according to installation needs to improve installation convenience.

[0067] Please refer to Figure 3The first mounting base 1 includes a mounting box 101, which is embedded into a groove in the object during installation. A swing arm mounting groove 102 is provided on the top of the mounting box 101, facing downwards, to limit the movement of the swing arm mounting base 3. Symmetrical support platforms 103 are provided on both sides of the bottom of the swing arm mounting groove 102 to support the swing arm mounting base 3. Threaded holes 104 are provided on the top of both support platforms 103, and the threaded holes 104 cooperate with the swing arm mounting base connecting bolts 4 to fix the swing arm mounting base 3 at a height limit.

[0068] The second mounting base 2 includes a mounting plate 201, which is also embedded into the groove of the object during installation. A hinge frame 202 is provided on the side of the mounting plate 201 near the mounting box 101. A hinge groove is provided in the middle of the hinge frame 202. Two sets of horizontally arranged swing arm pin holes 203 are provided on both sides of the hinge groove. The swing arm pin holes 203 are hinged to the rotating swing arm 5 to realize rotation through the hinge point.

[0069] Example 2

[0070] The combined concealed hinge provided in Example 1 is further optimized, specifically, as follows: Figure 3 and Figure 6 As shown, there are two swing arm mounting seats 3, which are respectively located on both sides of the swing arm mounting slot 102. When the height of the swing arm mounting seats 3 needs to be adjusted, the two independent swing arm mounting seats 3 can be adjusted separately through the swing arm mounting seat connecting bolts 4, so that the two swing arm mounting seats 3 have different heights. This is used to adapt to non-planar installation requirements and further improve the flexibility of installation.

[0071] Specifically, the swing arm mounting base 3 includes a swing arm connecting plate 301, and a fixed connecting platform 302 is provided on the side of the swing arm connecting plate 301. The fixed connecting platform 302 is located directly above the supporting ladder 103. The fixed connecting platform 302 has a through hole in the vertical direction for the swing arm mounting base connecting bolt 4 to pass through for fixing. The swing arm mounting base connecting bolt 4 passes through the through hole on the fixed connecting platform 302 and is threadedly connected to the threaded hole 104. The side of the swing arm connecting plate 301 has a swing arm connecting hole 303, and the rotating swing arm 5 is hinged to the swing arm connecting hole 303. This realizes the linkage between the mounting box 101 and the mounting plate 201.

[0072] Through the above structural design, the height of each of the two swing arm mounting bases 3 can be individually adjusted by adjusting the connecting bolts 4 of the swing arm mounting bases, thereby placing the rotating swing arm 5 in a slightly tilted state. This allows for more flexible adaptation to different installation requirements.

[0073] It should be mentioned that, in order to improve the stability of the connection between the supporting platform 103 and the fixed connecting platform 302, anti-slip textures are provided on the top of the supporting platform 103 and the bottom of the fixed connecting platform 302. Under the pressure of the connecting bolts 4 of the swing arm mounting seat, the anti-slip textures on the top of the supporting platform 103 and the anti-slip textures on the bottom of the fixed connecting platform 302 interlock to improve the connection stability.

[0074] Example 3

[0075] The combined concealed hinges provided in Examples 1 and 2 are further optimized, such as... Figure 3 and Figure 6 As shown, the swing arm mounting base connecting bolt 4 includes a threaded rod 401 and a locking nut 403. A limiting platform 402 is provided in the middle of the threaded rod 401. The bottom of the threaded rod 401 is threadedly connected to the threaded hole 104, and the top of the limiting platform 402 overlaps with the bottom of the fixed connecting platform 302. The height of the limiting platform 402 is adjusted by adjusting the connection depth between the bottom of the threaded rod 401 and the threaded hole 104, thereby changing the installation height of the swing arm mounting base 3. The locking nut 403 is threadedly connected from the top of the fixed connecting platform 302 to the upper part of the threaded rod 401, and works with the fixed connecting platform 302 to fix the height position of the swing arm connecting plate 301.

[0076] Example 4

[0077] The combined hidden hinges provided in the above embodiments are further optimized, such as... Figure 3 and Figure 7 As shown, the rotating arm 5 includes a first arm 501 and a second arm 502. Both ends of the first arm 501 and the second arm 502 are hinged to the arm pin hole 203 and the arm connecting hole 303, respectively. The first arm 501 is located above the second arm 502 and is supported by the second arm 502. Specifically, when the hinge is closed to a predetermined position, the second arm 502 at the bottom limits the first arm 501, preventing further rotation. When the hinge is extended to its maximum angle, the second arm 502 limits the first arm 501, preventing further rotation, thus achieving stable support after opening and closing.

[0078] To increase the unfolding angle of the rotating arm 5, the side of the arm mounting groove 102 is open. When the arm mounting base 3 is lowered and installed inside the arm mounting groove 102, the rotating arm 5 can rotate from the open position of the arm mounting groove 102, avoiding rotational interference of the rotating arm 5 caused by the edge of the arm mounting groove 102.

[0079] Example 5

[0080] The combined hidden hinges provided in the above embodiments are further optimized, such as... Figures 8-10As shown, a baffle 204 is provided at the top between the hinge slots of the hinge frame 202. The baffle 204 supports the first swing arm 501 after the mounting plate 201 is unfolded, maintaining the unfolded angle of the mounting plate 201. Specifically, the purpose of the baffle 204 is to limit the rotation angle of the rotating swing arm 5 when the swing arm mounting base 3 is installed too high, preventing excessive flipping of the mounting plate 201. This can be used to meet the installation requirement where the mounting box 101 and the mounting plate 201 are not on a horizontal plane, but located on the side, achieving a second installation configuration.

[0081] When necessary, decorative panels 6 are provided on both sides of the top of the mounting box 101, covering the two wings of the mounting box 101. These panels protect the bolts at the connection points between the mounting box 101 and the solid, improving aesthetics and reducing the risk of corrosion and rust.

[0082] The automatic column-passing device provided by this utility model is used as follows:

[0083] The mounting box 101 and mounting plate 201 are respectively fixed in the two solid grooves, and then the threaded rod 401 is installed inside the threaded hole 104. Then, the rotating arm 5 is rotated so that the hinged arm connecting plate 301 on the rotating arm 5 extends into the arm seat mounting groove 102, and the upper end of the threaded rod 401 passes through the fixed connecting platform 302. Then, the threaded rod 401 is rotated to adjust the height of the limiting platform 402 so that the arm connecting plate 301 reaches the required installation position. Finally, the arm connecting plate 301 is locked by the engagement of the locking nut 403 and the threaded rod 401, so that the position of the arm connecting plate 301 is finally determined.
