[0012] Beneficial Effects

[0013] Compared with the prior art, the advantages of the adjustable door opening angle hinge of the present invention are:

[0014] 1. When in use, when the adjustment structure is adjusted to the negative angle, that is, the higher side of the bottom of the adjustment structure will rotate to the power stack of the hinge and hold up the power stack, so as to lock the opening angle of the hinge. At this time, the opening angle is 80-85 degrees, which can prevent the door panel from being damaged due to collision when it is opened. When the adjustment structure is adjusted to the positive angle, the higher side of the bottom of the adjustment structure will leave the power stack of the hinge, and the hinge cup will return to the original opening angle, that is, 110 degrees, so as to achieve the effect of fully opening the door panel. The hinge structure is simple, and there is no need to specially customize adjustment accessories and hinges. The product structure is slightly changed, the cost is low, and it can be freely matched with the user's cabinet usage scenario.

[0015] 2. A limit point and a reset point are set outside the swing arm. When rotating the adjustment structure, let the directional mark on the adjustment structure face one of the limit point or the reset point, so that personnel can intuitively judge whether the adjustment structure is rotated into place.

[0027] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] Example

[0029] The specific embodiments of the present invention are as follows Figures 1 to 9 As shown, an adjustable door opening angle hinge comprises a hinge cup 1, a swing arm 2, an arm body 3 and a power laminate 6. One end of the swing arm 2 is rotatably connected to the hinge cup 1 via a first rotating shaft 11, and the other end of the swing arm 2 is rotatably connected to the arm body 3 via a third rotating shaft 21. One end of the power laminate 6 is rotatably connected to the hinge cup 1 via a second rotating shaft 12, and the other end of the power laminate 6 is rotatably connected to the arm body 3 via a fourth rotating shaft 31. An adjustment structure 4 for adjusting the distance between the swing arm 2 and the power laminate 6 is provided on the swing arm 2.

[0030] The adjusting structure 4 is rotatably matched with the swing arm 2. An inclined surface 43 is provided at one end of the adjusting structure 4. An acute angle is formed between the inclined surface 43 and the rotation axis of the adjusting structure 4. Figure 4 shown.

[0031] In this embodiment, a protrusion 61 is provided in the middle of the power lamination 6 , and the protrusion 61 contacts one end of the adjustment structure 4 where the inclined surface 43 is provided.

[0032] A first plane 41 and a protruding structure 42 are further provided at one end of the adjustment structure 4. The first plane 41, the inclined surface 43 and the protruding structure 42 are arranged in sequence. The first plane 41 and the protruding structure 42 are respectively located on both sides of the rotation axis of the adjustment structure 4. The protruding structure 42 is higher than the first plane 41.

[0033] The adjustment structure 4 includes a cylindrical portion 44 and a disc-shaped portion 45 arranged in sequence along its axial direction. The first plane 41, the inclined surface 43, and the protruding structure 42 are all arranged on the end of the disc-shaped portion 45 away from the cylindrical portion 44. A through hole is provided in the middle of the swing arm 2, and the disc-shaped portion 45 is located on the inner side of 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, which can prevent the adjustment structure 4 from slipping out of the swing arm 2. One end of the cylindrical portion 44 passes through the through hole of the swing arm 2 to the outside of the swing arm 2. An operating portion 46 is provided on the cylindrical portion 44. In this embodiment, the operating portion 46 on the cylindrical portion 44 adopts a cross groove that matches 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 limit point 22 and a reset point 23, and the limit point 22 and the reset point 23 are arranged around the outer side of the adjustment structure 4. A directional mark 47 is provided on the top of the cylindrical portion 44 of the adjustment structure 4, such as Figure 8 , 9 shown.

[0035] The hinge also includes a hinge seat 5. When installing the hinge, first install the hinge cup on the door body by screws, install the hinge seat 5 on the inner wall of the cabinet by screws, and then clamp the bottom of the arm body 3 on the hinge seat 5 (here is the installation method of the traditional hinge), and the installation of the hinge can be completed.

[0036] When the maximum opening angle of the cabinet door needs to be adjusted, when the adjustment structure 4 rotates to point the mark 47 toward the reset point 23, the higher raised structure 42 at the bottom of the adjustment structure 4 will rotate onto the power laminate 6 of the hinge and support the raised portion 61 of the power laminate, thereby locking the hinge opening angle. Figure 6 As shown, the opening angle is 80-85 degrees at this time, which prevents the door panel from being damaged due to collision when it is opened. When the adjustment structure 4 rotates to the direction mark 47 toward the limit point 22, that is, the higher convex structure 42 at the bottom of the adjustment structure 4 will leave the convex part 61 of the power laminate 6 of the hinge, and the first plane 41 is arranged adjacent to the convex part 61 of the power laminate 6, as shown in FIG. Figure 3 and Figure 7 As shown, the hinge cup 1 of the hinge has an opening angle of 110 degrees, thereby achieving the effect of fully opening the door panel. The hinge structure is simple, no special custom adjustment accessories and hinges are required, the product structure is slightly changed, the manufacturing cost is low, and it can be freely matched with the user's cabinet usage scenario.

[0037] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
