[0020] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-4 As shown, the hinge includes a movable hinge 1, a fixed hinge 2, and a pivot 3. One end of the fixed hinge is L-shaped, and one side of this end is hinged to one side of the movable hinge via the pivot and connected as a whole. The movable hinge is L-shaped, and the other end of the fixed hinge is raised and has an irregularly shaped notch with an opening above the pivot. This end of the fixed hinge has an outwardly protruding right-angled block edge 201, which is fixedly installed in the right-angled groove edge at the outer corner of the door frame 10. One side of the movable hinge is set in the middle opening of the pivot side of the fixed hinge via the pivot, while the other side of the movable hinge extends out of the bottom of the irregularly shaped notch edge at the middle opening of the pivot side of the fixed hinge in an L-shape and is fixedly connected to the door panel 9. The door panel flips open around the pivot and along the outside of the right-angled groove edge of the door frame. An annular groove is provided in the middle of the pivot. The movable hinge is hinged to the fixed hinge through the pivot and connected as one unit. At the same time, the end of the third locking screw 8 screwed into one side of the movable hinge is inserted into the annular groove of the pivot.

[0021] The edge of the aforementioned door panel is curved at a 90-degree angle to wrap around the outer side of the movable hinge. The curved edge of the door panel is flush with the outer diameter of the door frame and has a gap for flipping open and closing, the gap being in the range of 1mm-2mm. When the door panel is open, the end of the curved edge of the door panel is limited to the inner diameter of the irregular recess of the fixed hinge. The two right-angled edges of the outer right-angled block of the fixed hinge are fixedly installed in the right-angled groove of the door frame by the first locking screw 5 and the second locking screw 7, respectively. The outer right-angled block of the fixed hinge and the outer diameter of the right-angled groove of the door frame are respectively provided with a first sealing ring 4 and a second sealing ring 6.

[0022] The corresponding sealing rings are respectively fixedly arranged in the sealing grooves of the mounting surfaces on both sides of the fixed hinge, and are mounted on the door frame through corresponding locking screws. The sealing rings play a waterproof sealing role. The movable hinge is adjustably mounted on the door plate through the two side waist holes. The movable hinge and the fixed hinge are assembled through the rotating shaft. The movable hinge is locked by the locking screw in the middle. Since the special-shaped notch of the fixed hinge adopts the inner notch material penetrating structure, the door plate and the door frame can be used in theoretical simulation of static and motion scenarios. Thus, the movable hinge can drive the door plate to open to the maximum angle with sufficient avoidance space, and the gap between the door bodies is small after closing. Meanwhile, the movable hinge, the fixed hinge and the corresponding components are made of zinc die casting to save materials.

[0023] According to the above structural features, as shown in Figure 5 The sealing strip 11 can also be arranged at the edge of the door frame end of the inner side of the door plate. When the door plate is closed, the inner side of the door plate is sealed against the sealing strip of the door frame. Furthermore, the movable hinge is hingedly connected to the fixed hinge through the rotating shafts punched on both sides of the fixed hinge and is integrated, and a torsion spring is arranged at the hinge of the fixed hinge.

[0024] In summary, the hinge optimizes the traditional structure, which is composed of a movable hinge, a fixed hinge, a rotating shaft, a locking screw and a sealing ring. The linkage opening and closing of the movable hinge and the fixed hinge are effectively realized, and the sealing performance is good. The movable hinge can drive the door plate to open to the maximum angle with sufficient avoidance space, and the gap between the door bodies is small. Meanwhile, the hinge has the following advantages: 1) the movable hinge is made into an integrated self-locking screw structure, which effectively utilizes the space and prevents the rotating shaft from falling off; 2) the sealing grooves are arranged on the mounting surfaces on both sides of the fixed hinge, which optimizes the waterproof sealing performance and prolongs the service life; 3) the inner side of the fixed hinge adopts the notch material penetrating structure, thereby reducing the material cost. In addition, the gap between the door bodies is small in the closed state, the door body opening angle is larger, and the durability and safety of the door body are improved; 4) the rotating shaft of the connecting part adopts the cold heading process, and the middle part is a slotted structure, which reduces the friction between parts, prevents falling out, facilitates installation and removal, avoids scratching the paint, and improves the use space.
