[0036] Reference Figures 1 to 7 A robust hinge includes a first base 100 and a main adjusting assembly. The first base 100 has a through-hole 110 extending through it. The main adjusting assembly includes a first adjusting seat 210, a first adjusting screw 220, a second adjusting seat 230, and a second adjusting screw 240. The first adjusting seat 210 is located on the front side of the first base 100 (the side where the user can observe and operate the hinge when the door is open after installation), and the second adjusting seat 230 is located on the back side of the first base 100 (the side located inside the door or door frame after installation). The first adjusting seat 210 and the second adjusting seat 230 clamp the first base 100. The second adjusting seat 230 has an insertion part 231 and an adjusting part 232. The insertion part 231 passes through the through-hole 110 and abuts against the first adjusting seat 210. The first adjusting seat 210 has a first hole 211, and a first adjusting screw 220 passes through the first hole 211 and the insertion part 231 to fasten the first adjusting seat 210 and the insertion part 231 together. The adjusting part 232 has a second hole 2321, and a second adjusting screw 240 passes through the second hole 2321 and the first base 100 to lock the adjusting part 232 and the first base 100 together. The first hole 211 is a vertically extending hole, and the second hole 2321 is a front-to-back extending hole. In some embodiments, the positions of the first adjusting seat 210 and the second adjusting seat 230 can be interchanged, and the extension directions of the first hole 211 and the second hole 2321 can be interchanged, which can be configured according to actual conditions. When position adjustment is required, the first adjusting screw 220 and the second adjusting screw 240 can be loosened, and the first hole 211 and the second hole 2321 can be used for adjustment in two directions.
[0037] In the above structure, the first adjusting seat 210 and the second adjusting seat 230 are respectively disposed on the front side and the back side of the first base 100 and clamp the first base 100. The second adjusting seat 230 is provided with an insertion part 231 and is connected to the first adjusting seat 210 through the insertion part 231. Thus, the first adjusting seat 210 and the second adjusting seat 230 form an "I" shaped structure to clamp the first base 100. The first adjusting screw 220 is provided between the first adjusting seat 210 and the second adjusting seat 230 for locking, and the second adjusting screw 240 is provided between the second adjusting seat 230 and the first base 100 for locking. The above structure has balanced force and good structural stability. In addition, since it can avoid the two adjusting seats being disposed on the front side of the first base 100 at the same time, the adjusting seat located on the back side does not require additional surface treatment, thereby helping to reduce manufacturing costs.
[0038] In the embodiment, the insertion part 231 is adapted to the relief through hole 110 and slides along the extension direction of the second hole 2321 with the relief through hole 110, thereby making the second adjustment seat 230 move to the adjustment position more stably and further improving the stability of the structure.
[0039] In this embodiment, the first base 100 is provided with a facing surface opposite to the first adjusting seat 210, and the through hole 110 is opened on the facing surface. The end face of the insertion part 231 that abuts against the second adjusting seat 230 is higher than the facing surface, so that when adjusting the position of the second adjusting seat 230 relative to the first base 100, the first adjusting seat 210 will not rub against the first base 100, reducing the impact on the position adjustment.
[0040] In this embodiment, the insertion part 231 and the adjustment part 232 are arranged along the extension direction of the second hole 2321, thereby making the structure more balanced and helping to further improve the structural stability.
[0041] In this embodiment, the insertion part 231 is provided with a first screw hole 2311, and a first adjusting screw 220 is threaded into the first screw hole 2311. The first base 100 is provided with a second screw hole 120, and a second adjusting screw 240 is threaded into the second screw hole 120. The first adjusting screw 220 and the second adjusting screw 240 are installed in opposite directions. With this structure, on the one hand, screw holes are directly provided in the insertion part 231 and the first base 100, facilitating the threaded connection of the first adjusting screw 220 and the second adjusting screw 240. On the other hand, the opposite installation directions of the first adjusting screw 220 and the second adjusting screw 240 create a cross-tightening, which further enhances the structural stability. It should be understood that the opposite installation directions of the first adjusting screw 220 and the second adjusting screw 240 mean that the screw tails point in opposite directions.
[0042] In one embodiment, the head of the first adjusting screw 220 and the tail of the second adjusting screw 240 are located on the front side of the first base 100. To facilitate the adjustment of the second adjusting screw 240 by rotating it on the front side, the tail of the second adjusting screw 240 is provided with a hexagonal groove. In some embodiments, the hexagonal groove can also be replaced by a slotted groove or a cross groove.
[0043] In this embodiment, the first adjusting seat 210 is provided with a second adjusting seat 230, a clearance through hole 110, a first adjusting screw 220, a second adjusting screw 240, a first slot 211, and a second slot 2321 at both ends along the vertical direction. With this structure, two adjustment and connection points are formed at both ends of the first adjusting seat 210, resulting in a more stable structure. It is conceivable that in some embodiments, the number of corresponding first adjusting seats 210 and second adjusting seats 230 may vary, and the specific configuration can be tailored to the actual situation.
[0044] In this embodiment, the hinge further includes a second base 300, a left-right adjustment seat 400, and a rotating arm assembly 500. The left-right adjustment seat 400 is disposed on the second base 300 and can be adjusted in the left and right position relative to the second base 300. The rotating arm assembly 500 connects the left-right adjustment seat 400 and the first adjustment seat 210. With the above structure, the left-right position of the first base 100 relative to the second base 300 can be adjusted by the left-right adjustment seat 400, thereby realizing the left-right adjustment of the door. Combined with the adjustment of the first adjustment seat 210 and the second adjustment seat 230, three-dimensional adjustment of the hinge can be realized.
[0045] In this embodiment, the swing arm assembly 500 includes a first swing arm 510, a slider 520, a second swing arm 530, and a secondary swing arm 540. One end of the first swing arm 510 is hinged to the first adjusting seat 210, and the other end of the first swing arm 510 is hinged to the slider 520. The slider 520 is slidably disposed on the left and right adjusting seats 400. One end of the second swing arm 530 is hinged to the left and right adjusting seats 400, and the other end of the second swing arm 530 is hinged to one end of the secondary swing arm 540. The other end of the secondary swing arm 540 is hinged to the first adjusting seat 210. The first swing arm 510 and the second swing arm 530 are hinged to each other at their non-end points. In this embodiment, the other end of the first swing arm 510 is provided with a pivot, and is hinged to the slider 520 through the pivot. With the above structure, the swing arm assembly 500 is a three-arm structure, which is simple and easy to implement. It is conceivable that in some embodiments, the swing arm assembly 500 may also adopt other structures, which can be configured according to the actual situation.
[0046] In this embodiment, the left and right adjustment seat 400 is provided with an arc-shaped groove 410, and the slider 520 is slidably disposed in the arc-shaped groove 410. The arc-shaped groove 410 defines the sliding trajectory of the other end of the first rotating arm 510, resulting in smooth movement.
[0047] In this embodiment, the second base 300 is rotatably provided with left and right adjusting studs 600 at its upper and lower ends corresponding to the left and right adjusting seat 400. The left and right adjusting studs 600 are arranged in the left-right direction. The upper and lower ends of the left and right adjusting seat 400 are respectively provided with third screw holes 420, and the left and right adjusting seat 400 is threadedly connected to the left and right adjusting studs 600 through the third screw holes 420. When the left and right adjusting studs 600 are rotated, the left and right adjusting seat 400 can be moved left and right through the threaded structure, thereby achieving position adjustment. It is conceivable that in some embodiments, the left and right adjustment of the left and right adjusting seat 400 is not limited to the above-described implementation method; for example, a structure with a slotted hole and screw can be used, and the specific configuration can be adjusted according to the actual situation.
[0048] In this embodiment, the left and right adjustment seat 400 includes two sub-seat bodies 430 and a fixing plate 440. Each sub-seat body 430 has a slot 431, and the fixing plate 440 has a retaining strip 441. The sub-seat bodies 430 are engaged with the retaining strip 441 via the slots 431 and are fixed to the fixing plate 440 by screws. Each sub-seat body 430 has an arc-shaped groove 410. Sliding members 520 are hinged to both sides of the other end of the first rotating arm 510, thereby respectively engaging with the arc-shaped grooves 410 of the two sub-seat bodies 430.
[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
