[0028] See Figures 1 to 4, An adjustable hinge structure of the present invention includes: a first mounting seat 100, a second mounting seat 200, and a hinge mechanism 300 movably connected between the first mounting seat 100 and the second mounting seat 200; a first adjusting seat 400, provided on the first mounting seat 100, connected to the hinge mechanism 300, and capable of being adjusted up and down relative to the first mounting seat 100; a second adjusting seat 500, provided on the second mounting seat 200, connected to the hinge mechanism 300, and capable of being adjusted left and right relative to the second mounting seat 200; an eccentric driving member 600 is movably provided on the first adjusting seat 400 and / or the second adjusting seat 500, and rotating the eccentric driving member 600 can drive the first adjusting seat 400 to move up and down relative to the first mounting seat 100, or can drive the second adjusting seat 500 to move left and right relative to the second mounting seat 200. Among them, one of the first mounting seat 100 and the second mounting seat 200 is used to connect the door panel, and the other is used to connect the door frame.

[0029] When it is necessary to adjust the relative position of the door panel in the up and down direction and / or the left and right direction, only need to drive the eccentric driving member 600 to rotate to drive the first adjusting seat 400 to move up and down relative to the first mounting seat 100 or drive the second adjusting seat 500 to move left and right relative to the second mounting seat 200. The adjustment operation is convenient, there is no need to lift the door panel, which saves time and effort. Moreover, the way of using the eccentric driving member 600 to push the first adjusting seat 400 and / or the second adjusting seat 500 to move is more stable and reliable than the traditional way of fixing the door panel with fastening screws, and the adjustment accuracy is higher.

[0030] See Figure 1 , Figure 2 and Figure 3 , in some embodiments of the present invention, the first adjusting seat 400 is provided with a first long strip through hole 410 extending in the up and down direction, the first mounting seat 100 is provided with a first guiding column 110 passing through the first long strip through hole 410, the first mounting seat 100 is provided with a first guiding hole 120 extending in the left and right direction, and the first adjusting seat 400 is rotatably provided with an eccentric driving member 600, and the eccentric driving member 600 has a first eccentric guiding column 610 extending into the first guiding hole 120. The cooperation between the first guiding column 110 and the first long strip through hole 410 limits the first adjusting seat 400 to only move up and down relative to the first mounting seat 100. When the eccentric driving member 600 on the first adjusting seat 400 rotates, the first eccentric guiding column 610 abuts against the upper side or the lower side of the first guiding hole 120 to push the first adjusting seat 400 to move up or down. During this process, the first eccentric guiding column 610 displaces along the extending direction of the first guiding hole 120. Through the above structure, the position adjustment of the first adjusting seat 400 in the up and down direction can be realized, and the adjustment process is stable and reliable, without the need to lift the door panel by external force or remove the door panel from the hinge structure, and the operation is very convenient.

[0031] SeeFigure 1 and Figure 2 In some embodiments of the present invention, for the convenience of an operator to twist the eccentric driving member 600, a first hexagonal bolt head is provided at the end of the eccentric driving member 600, and the eccentric driving member 600 can be screwed by a screwdriver with a hexagonal head. Wherein, the center line of the first hexagonal bolt head is located on the rotation axis of the eccentric driving member 600, that is, the center line of the first hexagonal bolt head is relatively offset from the first eccentric guiding column 610. A first pointing mark 420 corresponding to the eccentric driving member 600 is provided on the first adjusting seat 400, and the first pointing mark 420 is used to prompt the user that rotating the eccentric driving member 600 can drive the first adjusting seat 400 to move up and down.

The eccentric driving member 600 has a second eccentric guiding column 630 extending into the second guiding hole 220. The cooperation between the second guiding column 210 and the second long strip perforation 510 limits the second adjusting seat 500 to only displace left and right relative to the second mounting seat 200. When the eccentric driving member 600 on the second adjusting seat 500 rotates, the second eccentric guiding column 630 abuts against the left or right side of the second guiding hole 220 and pushes the second adjusting seat 500 to move left or right. During this process, the second eccentric guiding column 630 displaces along the extending direction of the second guiding hole 220. Through the above structure, the position adjustment of the second adjusting seat 500 in the left - right direction can be realized, and the adjustment process is stable and reliable, without the need to lift the door panel by external force or remove the door panel from the hinge structure, and the operation is very convenient.
