[0019] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0020] like Figure 1 to Figure 3 As shown, a built-in hinge structure of a safe includes a frame hinge 1 and a door hinge 2. The frame hinge 1 is arranged in the box body of the safe, and the door hinge 2 is arranged in the door panel of the safe. Door pins 3 are arranged in the frame hinge 1 and the door hinge 2. Steel balls 1 4 and 2 5 are arranged at the bottom of the door pin 3. Steel ball 1 4 is located below steel ball 2 5. An adjusting screw 6 is arranged at the bottom of steel ball 1 4. The adjusting screw 6 lifts up steel ball 1 4 from the bottom.
[0021] In this embodiment, door pin hole one and door pin hole two are respectively processed in the frame hinge 1 and the door hinge 2, and the door pin 3 is arranged in the door pin hole one and the door pin hole two. The steel ball one 4 and the steel ball two 5 are arranged at the bottom of the door pin hole two. Steel ball one 4 and steel ball two 5 use two steel balls, one small and one large. Usually, steel ball one 4 uses a φ6mm steel ball, and steel ball two 5 uses a φ8mm steel ball.
[0022] An opening is provided on the side of the second door pin hole, and a baffle 8 is provided on the opening surface. One side of the baffle 8 is installed on the door hinge 2 by screws. In this embodiment, the first door pin hole is a round hole, and a door pin sleeve 7 is provided between the door pin 3 and the first door pin hole. The door pin sleeve 7 is used to eliminate the gap between the door pin 3 and the first door pin hole to facilitate the rotation of the door pin 3. The second door pin hole is a square hole, and a long strip opening 9 is provided on the side of the second door pin hole to facilitate the door pin 3 to enter the second door pin hole from the long strip opening 9. The side length of the second door pin hole is 0.01 mm smaller than the diameter of the door pin. After the baffle 8 is installed, one end of the door pin 3 is clamped in the second door pin hole.
[0023] In this embodiment, the adjusting screw 6 is a hexagon socket cone-end set screw, which is connected to the baffle 8. Since the hexagon socket cone-end set screw has a tapered end, the tapered end is used to facilitate lifting the steel ball during the door gap adjustment process.
[0024] like Figure 4 and Figure 5 As shown, a positioning plug welding hole 10 is processed on the body of the safe, a positioning opening 11 is opened on the door panel of the safe, and a positioning boss 12 is processed on the top of the frame hinge 1. When the frame hinge 1 and the body of the safe are installed, the positioning boss 12 is inserted into the positioning plug welding hole, and then the frame hinge 1 is fixed at the positioning plug welding hole 10 by welding. The door hinge 2 is arranged in the positioning opening 11, and a plug welding hole 13 is opened on the side of the door panel of the safe, and the door hinge 2 is fixed at the plug welding hole 13 by welding.
