Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] For vertical hinges, please refer to [link / reference]. Figure 1-5 As shown, it includes: a fixed base 100, a housing 200, a transmission assembly 300, a fixed power arm 400, and a swing arm 500.

[0030] Both the fixing base 100 and the outer shell 200 have a Π-shaped cross-section, and the fixing base 100 and the outer shell 200 are made of high-hardness metal material in one piece.

[0031] The fixed power arm 400 is connected between the fixed base 100 and the outer shell 200. The fixed power arm 400 can improve the load-bearing capacity of the entire vertical hinge.

[0032] like Figure 2-3 As shown, the fixed power arm 400 is also made of high-hardness metal material in one piece. The fixed power arm 400 includes: a left support plate 401 and a right support plate 402 arranged symmetrically, and the left support plate 401 and the right support plate 402 are connected to each other.

[0033] A gap is formed between the left support plate 401 and the right support plate 402, and the swing arm 500 passes through this gap during assembly.

[0034] The fixed power arm 400 is rotatably connected to the outer shell 200 by a pin, and the fixed power arm 400 is locked to the fixed seat 100 for a limit position; when the vertical hinge is running, the fixed power arm 400 and the outer shell 200 rotate relative to each other around the pin.

[0035] The swing arm 500 is connected to the housing 200 and the transmission assembly 300. The swing arm 500 passes through the fixed base 100. Specifically, the fixed base 100 is provided with a hole 110 near the lower part for the swing arm 500 to pass through, and the swing arm 500 moves within the hole 110.

[0036] like Figure 2 As shown, the 500 swing arm is a long arm, made of a single piece of high-hardness metal, such as... Figure 3-4 As shown, one end of the swing arm 500 extends into the housing 200 and is connected to the housing 200 by a pin and a flower wheel. The connection point between the swing arm 500 and the housing 200 is defined as the first connection hole 502. A second connection hole 503 is provided near the first connection hole 502. The second connection hole 503 is connected to the transmission component 300. When the housing 200 swings relative to the fixed base 100, it pulls the swing arm 500 to swing.

[0037] Furthermore, the fixed power arm 400 also passes through the hole 110 and is engaged in the hole 110. Specifically, the fixed power arm 400 is provided with a slot 420, and the fixed seat 100 partially engages in the slot 420, forming a side wall of the hole 110.

[0038] So, if Figure 4 As shown, after the fixed power arm 400 is installed, one end of the fixed power arm 400 extends into the lower part of the housing 200 and is rotatably connected to the housing 200; the other end of the fixed power arm 400 passes through the hole 110 and extends into the fixed seat 100 and is locked and limited by the fixed seat 100.

[0039] Furthermore, the fixed power arm 400 is provided with a roller 410, which corresponds to the side 501 of the swing arm 500;

[0040] When the outer shell 200 and the fixed base 100 rotate relative to each other to open and close under external force, the transmission component 300 plays a buffering role during the opening and closing process; when the fixed base 100 moves, the roller 410 moves along the side 501 of the swing arm 500.

[0041] In this embodiment, the outer casing 200 swings, thereby driving the swing arm 500 to move. In actual application, the vertical hinge can be installed in an oven, such as the outer casing 200 being installed on the oven body and the fixed base 100 being installed on the oven door. When the user pulls the oven door, the relative positions of the fixed base 100 and the outer casing 200 change, and the swing arm 500 moves within the fixed base 100. The fixed power arm 400 can increase the load-bearing capacity of the vertical hinge.

[0042] In one embodiment, the conductive assembly 300 includes a compression spring guide rod 310 and a compression spring 320, with the compression spring 320 sleeved on the compression spring guide rod 310; one end of the swing arm 500 is rotatably connected to the housing 200 and the end of the compression spring guide rod 310 respectively; when the housing 200 swings, the compression spring guide rod 310 moves within the housing 200 and deforms the compression spring 320.

[0043] Furthermore, the compression spring guide rod 310 is provided with a limiting part 311 that limits the lower end of the compression spring 320, and a strip groove 312 is provided at the upper end of the compression spring guide rod 310. A pin is provided in the strip groove 312. The compression spring guide rod 310 is limited to the outer shell 200 by the pin, and the upper end of the compression spring 320 is limited by the pin.

[0044] During the use of the vertical hinge, the guide rod 310 moves within the housing 200, causing the compression spring 320 to deform. The elastic force generated by the deformation of the compression spring 320 enables the vertical hinge to open and close slowly.

[0045] Furthermore, under the elastic force of the compression spring 320, the roller 410 and the side 501 of the swing arm 500 are always kept in a state of mutual pressure, so that the roller 410 moves along the side 501.

[0046] In one embodiment, one end of the fixed power arm 400 is rotatably connected to the housing 200, and the other end is provided with a roller 410; the side 501 of the swing arm 500 is provided with a first positioning groove 510 into which the roller 410 is engaged when the arm is closed and a second positioning groove 520 into which the roller 410 is engaged when the arm is open.

[0047] like Figure 4 As shown, when the vertical hinge is in the closed state, the roller 410 slides to the limit position within the first positioning groove 510;

[0048] like Figure 5 As shown, Figure 5 The neutral hinge has not yet fully opened to its maximum angle, so the roller 410 has not yet slid into the second positioning groove 520. When the upright hinge is opened to its maximum angle, the roller 410 should slide into the second positioning groove 520 and be stopped.

[0049] like Figure 2 As shown, a hook portion 502 is formed at the end of the swing arm 500. The hook portion 502 and the main body of the swing arm 500 form the second positioning groove 520. The second positioning groove 520 can limit the maximum opening angle of the vertical hinge and prevent the vertical hinge from being over-opened, which could lead to damage.

[0050] In one embodiment, the fixed power arm 400 is equipped with a latch 430, which facilitates the installation of a vertical hinge.

[0051] The specific working principle of this utility model is further explained below:

[0052] During installation, the outer casing 200 can be installed on the oven main unit, the fixed base 100 and the swing arm 500 can be installed on the oven door, and the fixed power arm 400 can be connected between the fixed base 100 and the swing arm 500 to effectively enhance the load-bearing capacity.

[0053] When opened, force is applied to rotate the oven door, and the fixed base 100 and the outer shell 200 rotate relative to each other. The swing arm 500 moves outward in the hole 110 of the fixed base 100, and the roller 410 presses against the side 501 of the swing arm 500 as it moves.

[0054] When opened to the maximum angle, the roller 410 moves to the limit in the second positioning groove 520;

[0055] When closed, force is applied to rotate the oven door, and the fixed base 100 and the outer shell 200 rotate relative to each other. The swing arm 500 moves inward in the hole 110 of the fixed base 100, and the roller 410 leaves the second positioning groove 520 and presses against the side 501 of the swing arm 500 to move.

[0056] When rotated to the closed state, the roller 410 moves to the limit position in the first positioning groove 510.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
