Means for Solving the Problems

[0006] To achieve the above object, the present invention provides a hinge with an adjustable opening angle. This includes a hinge cup, a swing arm, an arm body, and a power plate. One end of the swing arm is rotatably connected to the hinge cup via a first rotating shaft, and the other end of the swing arm is rotatably connected to the arm body via a third rotating shaft. One end of the power plate is rotatably connected to the hinge cup via a second rotating shaft, and the other end of the power plate is rotatably connected to the arm body via a fourth rotating shaft. An adjustment structure for adjusting the distance between the swing arm and the power plate is provided on the swing arm.

[0007] As a further improvement of the present invention, the adjustment structure is rotatably fitted to the swing arm, and a slope is provided at one end of the adjustment structure, with an acute angle between the slope and the rotation axis of the adjustment structure.

[0008] As a further improvement of the present invention, a first plane and a projection structure are further provided at one end of the adjustment structure, and the first plane, the inclined plane, and the projection structure are arranged in order, with the first plane and the projection structure located on opposite sides of the rotation axis of the adjustment structure.

[0009] As a further improvement of the present invention, the adjustment structure includes a cylindrical portion and a disc portion arranged sequentially along its axial direction, the first plane, the inclined surface, and the projection structure are all provided at the end of the disc portion away from the cylindrical portion, the disc portion is located inside the swing arm, one end of the cylindrical portion extends outward through the swing arm, and an operating portion is provided on the cylindrical portion.

[0010] As a further improvement of the present invention, the swingarm is provided with limit points and reset points, the limit points and reset points are arranged around the outside of the adjustment structure, and the adjustment structure is provided with directional markings.

[0011] As a further improvement of the present invention, a projection is provided in the center of the power plate, and the projection contacts the end of the adjustment structure that has a slanted surface. [Effects of the Invention]

[0012] The advantages of the hinge with an adjustable opening angle according to the present invention compared to the prior art are as follows:

[0013] 1. When the adjustment mechanism is adjusted to the negative angle side during use, that is, the higher side of the bottom of the adjustment mechanism rotates to the hinge's power plate and presses against the power plate, locking the hinge's opening angle. At this point, the opening angle is 80-85 degrees, preventing damage from collision when opening the door panel. When the adjustment mechanism is adjusted to the positive angle side, the higher side of the bottom of the adjustment mechanism separates from the hinge's power plate, and the hinge cup returns to its original opening angle, i.e., 110 degrees, thereby enabling the door panel to open completely. The hinge has a simple structure, does not require the special manufacture of adjustment parts or hinges, requires fewer changes to the product structure, is cost-effective, and can be easily adapted to the user's cabinet usage.

[0014] 2. Limit points and reset points are provided on the outside of the swingarm, and when the adjustment structure is rotated, the user can intuitively determine whether the adjustment structure has rotated to the predetermined position by pointing the direction indicator mark on the adjustment structure towards either the limit point or the reset point.

[0015] The present invention will become clearer with the following description and drawings. These drawings are for interpreting embodiments of the present invention. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. To more clearly explain the embodiments of the present invention, the drawings necessary for explaining the embodiments will be briefly introduced below. Needless to say, the drawings described below are only a part of the embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without special effort.

[0018] <Embodiment> Specific embodiments of the present invention are as shown in FIGS. 1 to 9, and are hinges with adjustable opening angles, including 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 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 plate 6 is rotatably connected to the hinge cup 1 via a second rotating shaft 12, and the other end of the power plate 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 plate 6 is provided on the swing arm 2.

[0019] The adjustment structure 4 is rotatably fitted to the swing arm 2, and a slope 43 is provided at one end of the adjustment structure 4. The slope 43 and the axis of rotation of the adjustment structure 4 form an acute angle, as shown in FIG. 4.

[0020] In this embodiment, a protrusion 61 is provided at the central portion of the power plate 6, and the protrusion 61 contacts the end portion of the adjustment structure 4 where the slope 43 is provided.

[0021] A first plane 41 and a projection structure 42 are further provided at one end of the adjustment structure 4. The first plane 41, the inclined surface 43, and the projection structure 42 are arranged in order, and the first plane 41 and the projection structure 42 are located on opposite sides of the rotation axis of the adjustment structure 4. The projection structure 42 is higher than the first plane 41.

[0022] The adjustment structure 4 includes a cylindrical portion 44 and a disc portion 45 arranged sequentially along its axial direction, with the first plane 41, the inclined surface 43, and the projection structure 42 all provided at the end of the disc portion 45 away from the cylindrical portion 44. A through hole is provided in the center of the swing arm 2, and the disc portion 45 is located inside the through hole of the swing arm 2. The cross-sectional contour of the disc portion 45 is larger than the through hole of the swing arm 2, preventing the adjustment structure 4 from coming off the swing arm 2. One end of the cylindrical portion 44 extends from the through hole of the swing arm 2 through the swing arm 2 to the outside. An operating portion 46 is provided on the cylindrical portion 44. In this embodiment, a cross groove corresponding to a screwdriver is used for the operating portion 46 of the cylindrical portion 44. 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 rotated and inserted into the inside of the hinge cup 1 in a normal manner.

[0023] The swingarm 2 is provided with a limit point 22 and a reset point 23, which are arranged around the outside of the adjustment structure 4. As shown in Figures 8 and 9, a directional indicator mark 47 is provided at the top of the cylindrical portion 44 of the adjustment structure 4.

[0024] The hinge further includes a hinge base 5. When installing the hinge, first attach the hinge cup to the door body with screws, then attach the hinge base 5 to the inner wall of the cabinet with screws, and then engage the bottom of the arm body 3 with the hinge base 5 (this is the conventional method of installing hinges), thereby completing the installation of the hinge.

[0025] When it is necessary to adjust the maximum opening angle of the cabinet door panel, rotating the adjustment structure 4 until the direction indicator mark 47 faces the reset point 23 causes the high projection structure 42 at the bottom of the adjustment structure 4 to rotate towards the hinge's power plate 6, pressing against the projection 61 of the power plate and locking the hinge's opening angle. As shown in Figure 6, at this point the opening angle is 80-85 degrees, preventing damage from collision when opening the door panel. When the adjustment structure 4 is rotated until the direction indicator mark 47 faces the limit point 22, the high projection structure 42 at the bottom of the adjustment structure 4 moves away from the projection 61 of the hinge's power plate 6, and at this point the first plane 41 is positioned adjacent to the projection 61 of the power plate 6. As shown in Figures 3 and 7, the opening angle of the hinge cup 1 of the hinge is 110 degrees, resulting in the effect of fully opening the door panel. This hinge has a simple structure, does not require the special manufacture of adjustment parts or hinges, requires minimal changes to the product structure, has low manufacturing costs, and can be easily adapted to the user's cabinet usage.

[0026] Although the present invention has been described above using optimal embodiments, the present invention is not limited to the embodiments disclosed above, and naturally includes various modifications and equivalent combinations based on the essence of the present invention.
