One end of the hinge plate 2 in the hinge base 1 is convexly provided with a cam plate 5, and the hinge base 1 is also internally provided with a reset pulling piece 3 and a buffer positioning piece 4 which are used for connecting the cam plate 5 or abutting against the side end surface of the cam plate 5. The middle section of the positioning shaft 25 is located on a toothed shaft 27, teeth on the toothed shaft 27 are preferably in a trapezoidal shape, a toothed hole 26 with the same specification is formed in the lower end of the hinge plate 2, and the hinge plate 2 and the positioning shaft 25 realize meshing rotation.

Referring to fig. 3 and 4, the return pulling member 3 includes an insertion rod 6, a connecting plate 7, and a first elastic member 8. The middle part of the hinge seat 1 is punched to form a plug board 18, the plug board 18 is provided with a jack 19, and the lower end of the hinge seat 1 is riveted with a plug rod 18-1 for positioning the lower end of the plug board 18, so that the upper end of the plug board 18 and the hinge seat 1 are prevented from being bent. The inserted link 6 realizes the insertion and sliding on the insertion plate 18 through the insertion hole 19, the front end of the inserted link 6 is connected with the connecting plate 7, the spring as the first elastic piece 8 is sleeved on the inserted link 6, the front end of the first elastic piece 8 is abutted and positioned on the insertion plate 18, and the tail end is positioned on the pressing plate 20 arranged at the tail end of the inserted link 6.

Referring to fig. 1 and 3, the connecting plate 7 is positioned inside the hinge base 1 and has a U-shape with an open upper end, while the front end is connected to the insert rod 6 and the rear end is connected to the cam plate 5. Wherein the connecting plate 7 is connected with the inserted link 6 through a sliding rod 22, and two ends of the sliding rod 22 are positioned in a second kidney-shaped hole 21 arranged on the side wall of the hinge base 1. The inserted link 6 is positioned on the insertion plate 18 through the second kidney-shaped hole 21 while the first elastic member 8 is always in a compressed state, and while the sliding rod 22 slides on the second kidney-shaped hole 21, the inserted link 6 continues to compress the first elastic member 8. The tail end of the connecting plate 7 is rotatably connected with the middle position of the cam plate 5 through a connecting shaft 24, and the position of the connecting shaft 24 is higher than the height of the positioning shaft 25.

Referring to fig. 2, 4 and 5, the buffering positioning member 4 is disposed at an opening at an upper end of the connecting plate 7, and includes a positioning rod 9, a second elastic member 10 and a sliding rod 11. The hinge base 1 is punched and formed with a positioning plate 14 downwards, and the positioning plate 14 is provided with a positioning hole 15 for the positioning rod 9 to be inserted. The front end of the positioning rod 9 is inserted into the positioning hole 15, the other end is provided with a positioning seat 9-1 with a larger diameter, the second elastic piece 10 is sleeved on the positioning rod 9, the front end is abutted against the surface of the positioning plate 14, and the tail end is positioned on the positioning seat 9-1. The upper end of the positioning seat 9-1 is also provided with a vertical sliding block 16, and the sliding block 16 is positioned in a sliding groove 17 arranged at the upper end of the hinge seat 1 to ensure that the positioning can stably slide.

Referring to fig. 1 and 5, the lower part of one side of the positioning seat 9-1 close to the hinge plate 2 is provided with an opening for the front end of the cam plate 5 to enter, meanwhile, the front end of the side is provided with an arc-shaped limiting groove 12, the sliding rod 11 is positioned in the arc-shaped limiting groove 12, and meanwhile, the two ends are positioned in first kidney-shaped holes 13 formed in the two side walls of the hinge seat 1. The positioning rod 9 is positioned by the sliding rod 11 and the positioning plate 14, and meanwhile, the sliding rod 11 is pressed at one end of the first kidney-shaped hole 13 close to the hinge plate 2 by the elastic potential energy of the first elastic piece 8 under the ordinary state, so that the outer wall of the sliding rod 11 can abut against the side end face of the cam plate 5. Two ends of the upper end of the connecting plate 7, which avoid the end close to the sliding rod 11, are provided with arc-shaped grooves 23 (refer to fig. 3) to avoid interference with the sliding rod 11 when the position of the connecting plate 7 is raised.

When the hinge plate 2 rotates on the hinge base 1, the connecting point of the connecting plate 7 and the connecting shaft 24 makes a circular motion by taking the positioning shaft 25 as the axis, so that the height of the connecting point is gradually increased and then gradually decreased along with the rotation of the hinge plate 2. However, since the other end of the connecting plate 7 has a constant height, when the position of the connecting point changes on the hinge base 1, the other end of the connecting plate 7 can pull the insert rod 6, and the first elastic member 8 is compressed. When the hinge plate 2 is relatively parallel to the hinge base 1, the connecting plate 7 is horizontally arranged with the hinge base 1 independently, and the first elastic piece 8 cannot pull the hinge plate 2 to rotate.

When the hinge plate 2 is pulled open, because the end face of the side of the cam plate 5 is abutted against the outer wall of the sliding rod 11, the cam plate 5 is positioned to abut against the sliding rod 11, when the foremost end of the cam plate 5 is gradually close to the sliding rod 11, the displacement of the sliding rod 11 on the first kidney-shaped hole 13 is gradually increased, and when the foremost end of the cam plate 5 is abutted against the sliding rod 11, the second elastic part 10 is compressed thoroughly, and the elastic potential energy is maximum. As the hinge plate 2 continues to be pulled apart, the foremost end of the cam plate 5 is separated from the slide lever 11, and the second elastic member 10 is restored. When the hinge plate 2 resets, when the first elastic component 8 can pull back the connecting plate 7 fast, but the second elastic component 10 can hinder the movement of the cam plate 5 on the sliding rod 11, and then can hinder the reset of the hinge plate 2, so as to play a role of buffering, avoid the hinge plate 2 from resetting fast, and lead to the collision of the cabinet door 29 and the cabinet body 28.

The second embodiment is a steaming and baking integrated box, referring to fig. 6, including a cabinet body 28 and a cabinet door 29, and further including a hinge frame as described in the first embodiment. The hinge plate 2 on the hinge base 1 is installed on the cabinet door 29, and the hinge base 1 is installed on the cabinet body 28.
