The above adjustable hinge structure is provided with a first distance adjustment mechanism 400 between the pivot 300 and the second connection portion 210 to adjust the relative position in the up and down direction between the first blade 100 and the second blade 200, and the second distance adjustment mechanism 600 is used to adjust the relative position in the front and back direction between the mounting plate 500 and the first blade 100, so as to realize the two-dimensional adjustment of the relative position between the door panel and the door frame. The hinge structure is simple in structure and is conducive to assembly and adjustment operations.

[0028] See Figure 5 , in some embodiments of the present invention, first distance adjustment mechanisms 400 are provided between the two pivots 300 and the corresponding second connection portions 210, and the user can adjust the relative height position between the first blade 100 and the second blade 200 at either end of the hinge structure.

[0029] Wherein, the first connection portion 110 and the first blade 100 are of an integral structure, the second connection portion 210 and the second blade 200 are of an integral structure, the whole of the first connection portion 110 and the second connection portion 210 is a cylinder, and the distance between the two second connection portions 210 is slightly larger than the axial dimension of the first connection portion 110 so that the first blade 100 and the second blade 200 can be adjusted up and down within a certain range.

[0030] See Figure 2 andFigure 4 In some embodiments of the present invention, the mounting plate 500 includes a bottom plate 510 and a panel 520 disposed on the bottom plate 510, a storage space 530 for accommodating the first leaf 100 is defined between the bottom plate 510 and the panel 520, and the second distance adjustment mechanism 600 includes at least one distance adjustment screw 610 that can only rotate relative to the mounting plate 500, and a first threaded hole 620 matching the distance adjustment screw 610 is provided on the first leaf 100 so that the first leaf 100 can move forward or backward in the storage space 530. The first leaf 100 can move closer to or away from the panel 520 by moving in the storage space 530, and the storage space 530 between the panel 520 and the bottom plate 510 can limit the movement stroke of the first leaf 100 relative to the mounting plate 500, so as to prevent the first leaf 100 from detaching from the mounting plate 500. Preferably, a plurality of distance adjustment screws 610 are provided, and the connecting lines between at least three distance adjustment screws 610 form a triangle, so as to achieve a more reliable adjustment effect.

[0031] See also Figure 2 and Figure 4 In some embodiments of the present invention, the distance adjusting screw 610 includes a distance adjusting rod portion accommodated in the storage space 530, and the distance adjusting rod portion is provided with a distance adjusting thread matching the first threaded hole 620. The two end surfaces of the distance adjusting rod portion respectively abut against the inner end surface of the bottom plate 510 and the inner end surface of the panel 520 to prevent the distance adjusting screw 610 from moving forward or backward relative to the mounting plate 500, so that the distance adjusting screw 610 can only rotate relative to the mounting plate 500. Accordingly, the panel 520 and the bottom plate 510 are both provided with through holes for the two ends of the distance adjusting screw 610 to pass through.

[0032] See also Figure 1 and Figure 4 In some embodiments of the present invention, in order to lock the relative position between the first leaf 100 and the mounting plate 500 and prevent damage to the thread of the distance adjustment screw 610, at least one fastening screw 700 is threadedly connected between the mounting plate 500 and the first leaf 100. When adjusting the front-to-back distance between the first leaf 100 and the mounting plate 500, the fastening screw 700 is first loosened, and after the adjustment is completed, the fastening screw 700 is tightened. Among them, the first leaf 100 is provided with a second threaded hole 130 matched with the fastening screw 700, the panel 520 is provided with an abutting through hole 521 abutting against the head of the fastening screw 700, and the bottom plate 510 is provided with a clearance hole 511 for the rod of the fastening screw 700 to pass through.

[0033] In some embodiments of the present invention, the panel 520 is detachably mounted on the bottom plate 510 by mounting screws to facilitate the installation and replacement of components. Of course, in other embodiments, after the hinge structure is assembled, the panel 520 and the bottom plate 510 can also be fixed by welding or other fixing methods.

[0034] See Figure 2 and Figure 3 , in some embodiments of the present invention, the first distance adjustment mechanism 400 includes a threaded through hole 410 provided inside the second connecting portion 210, and one end of the rotating shaft 300 is provided with a threaded rod portion 420 that matches the threaded through hole 410. The other end of the rotating shaft 300 is inserted into the corresponding rotating shaft counterbore 120. A cross slot is provided on the threaded rod portion 420 for a screwdriver to extend into the threaded through hole 410 to rotate the threaded rod portion 420, and the second blade 200 can move along the axial direction of the rotating shaft 300, thereby adjusting the relative position between the first blade 100 and the second blade 200 in the up and down directions. As Figure 5 shown, in this embodiment, both rotating shafts 300 are provided with threaded rod portions 420. Correspondingly, threaded through holes 410 are provided on both second connecting portions 210.

[0035] See Figure 3 or Figure 5 , in some embodiments of the present invention, a plastic bushing 800 sleeved outside the rotating shaft 300 is provided in the rotating shaft counterbore 120, and the plastic bushing 800 can prevent rigid friction from occurring between the rotating shaft 300 and the rotating shaft counterbore 120. See Figure 3 , when the second blade 200 is connected to the door panel, the mounting plate 500 is connected to the door frame. The lower end surface of the upper rotating shaft 300 contacts the inner bottom surface of the corresponding plastic bushing 800, and there is a gap between the upper end surface of the lower rotating shaft 300 and the corresponding plastic bushing 800 for the first distance adjustment mechanism 400 to perform up and down adjustment.

[0036] In addition, in order to reduce the material cost, a through groove 111 penetrating through the two rotating shaft counterbores 120 is further provided inside the first connecting portion 110. In order to prevent the plastic bushing 800 from deforming greatly under the action of axial force and ensure the stability and service life of the hinge structure, a load-bearing gasket 112 is provided between the bottom surface of the plastic bushing 800 and the rotating shaft counterbore 120. The load-bearing gasket 112 is generally made of a metal material with good rigidity. In some embodiments of the present invention, at least one vent hole is provided on the plastic bushing 800, and the vent hole is opened at the bottom of the plastic bushing 800 and communicated with the rotating shaft counterbore 120. When the plastic bushing 800 is installed in the rotating shaft counterbore 120, the air in the rotating shaft counterbore 120 can be discharged outward to ensure that the outer bottom surface of the plastic bushing 800 closely adheres to the bottom surface of the rotating shaft counterbore 120.

[0037] SeeFigure 1 and Figure 3 , in some embodiments of the present invention, at least one kidney-shaped hole 220 is provided on the second blade 200. The length direction of the kidney-shaped hole 220 extends along the left-right direction of the second blade 200, and a second mounting screw 230 is inserted through the kidney-shaped hole 220. Combining the above structure can achieve three-dimensional adjustment between the door panel and the door frame, that is, adjusting the relative positions in the up-down, left-right, front-back and other directions between the door panel and the door frame.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
