[0012] Beneficial effects
[0013] Compared with the prior art, the advantages of the adjustable door opening angle hinge of this utility model are:
[0014] 1. During use, when the adjustment mechanism is adjusted to the negative angle, i.e., the higher side of the bottom of the adjustment mechanism rotates onto the hinge's drive plate and holds it in place, thus locking the hinge's opening angle to 80-85 degrees to prevent damage to the door panel due to impact when opening. When the adjustment mechanism is adjusted to the positive angle, the higher side of the bottom of the adjustment mechanism disengages from the hinge's drive plate, and the hinge cup returns to its original opening angle of 110 degrees, allowing the door panel to be fully opened. This hinge structure is simple, requiring no specially customized adjustment parts or hinges.

[0028] Example
[0029] The specific embodiments of this utility model are as follows: Figures 1 to 9 As shown, an adjustable door opening angle hinge includes a hinge cup 1, a swing arm 2, an arm body 3, and a power plate 6. One end of the swing arm 2 is rotatably connected to the hinge cup 1 via a first pivot 11, and the other end of the swing arm 2 is rotatably connected to the arm body 3 via a third pivot 21. One end of the power plate 6 is rotatably connected to the hinge cup 1 via a second pivot 12, and the other end of the power plate 6 is rotatably connected to the arm body 3 via a fourth pivot 31. The swing arm 2 is provided with an adjustment structure 4 for adjusting the distance between the swing arm 2 and the power plate 6.
[0030] The adjusting structure 4 rotates in conjunction with the swing arm 2. One end of the adjusting structure 4 is provided with an inclined surface 43, which forms an acute angle with the axis of rotation of the adjusting structure 4. Figure 4 As shown.
[0031] In this embodiment, the power stack 6 has a protrusion 61 in the middle, and the protrusion 61 is in contact with one end of the adjustment structure 4 that has an inclined surface 43.
[0032] One end of the adjustment structure 4 is also provided with a first plane 41 and a protrusion 42. The first plane 41, the inclined plane 43, and the protrusion 42 are arranged in sequence, with the first plane 41 and the protrusion 42 located on both sides of the rotation axis of the adjustment structure 4. The protrusion 42 is higher than the first plane 41.
[0033] The adjusting structure 4 includes a cylindrical portion 44 and a disc-shaped portion 45 arranged sequentially along its axial direction. The first plane 41, the inclined surface 43, and the protruding structure 42 are all located on the disc-shaped portion 45 at one end away from the cylindrical portion 44. A through hole is provided in the middle of the swing arm 2. The disc-shaped portion 45 is located inside the through hole of the swing arm 2. The cross-sectional profile of the disc-shaped portion 45 is larger than the through hole of the swing arm 2, preventing the adjusting structure 4 from dislodging from the swing arm 2. One end of the cylindrical portion 44 extends through the through hole of the swing arm 2 to the outside of the swing arm 2. An operating part 46 is provided on the cylindrical portion 44. In this embodiment, the operating part 46 on the cylindrical portion 44 adopts a cross-shaped groove that mates with a screwdriver. One end of the cylindrical portion 44 is substantially flush with the outer surface of the swing arm 2, ensuring that the swing arm 2 can be normally screwed into the inner side of the hinge cup 1.
[0034] The swing arm 2 is provided with a limiting point 22 and a reset point 23, which are arranged around the outside of the adjusting structure 4. The top of the cylindrical portion 44 of the adjusting structure 4 is provided with a directional marker 47, such as... Figure 8 , 9 As shown.
[0035] The hinge also includes a hinge base 5. When installing the hinge, first install the hinge cup on the door body with screws, then install the hinge base 5 on the inner side wall of the cabinet with screws, and then snap the bottom of the arm body 3 onto the hinge base 5 (this is the traditional installation method for hinges), and the installation of the hinge is completed.
[0036] When the cabinet door needs to be adjusted to its maximum opening angle, when the adjustment mechanism 4 is rotated until the indicator 47 faces the reset point 23, the higher protrusion 42 at the bottom of the adjustment mechanism 4 will rotate onto the hinge's power plate 6 and press against the protrusion 61 of the power plate, thus locking the hinge's opening angle. Figure 6 As shown, the opening angle is 80-85 degrees at this time to avoid damage to the door panel due to collision when opening. When the adjustment structure 4 is rotated to point the indicator 47 toward the limit point 22, that is, the higher protrusion 42 at the bottom of the adjustment structure 4 will move away from the protrusion 61 of the power plate 6 of the hinge. At this time, the first plane 41 is arranged adjacent to the protrusion 61 of the power plate 6, as shown. Figure 3 and Figure 7 As shown, the hinge cup 1 of the hinge opens to an angle of 110 degrees, thus achieving the effect of fully opening the door panel. This hinge has a simple structure, requires no special custom-made adjustment parts or hinges, requires minimal modification to the product structure, has low manufacturing costs, and can be easily adapted to the user's cabinet usage scenario.
[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
