The hinge device comprises two hinged bodies which are connected with each other, a movable connecting device arranged between the two hinged bodies, and the like. The two hinge bodies are respectively provided with a fixed connecting device.

As shown in fig. 1 to 4, one of the two hinge bodies is provided with an open frame body 1 having a rectangular shape, and is provided with a receiving notch or receiving space 2 or the like.

One of the two hinge bodies, namely, the open frame body 1 comprises two side frame edges 1a, a connected frame edge 1b fixedly connected to one end of the two side frame edges 1a, and the like. The receiving notch 2 is formed by an open inner space surrounded by both side rims 1a and the connected rim 1b.

The movable connecting device comprises coaxial line hole devices which are coaxially arranged on the two side frame edges 1a respectively, the coaxial line hole devices comprise coaxial line holes 3, and the coaxial line holes 3 are positioned at the free ends of the open frame body, which are close to the open mouth, namely close to the two side frame edges 1a, and are positioned at the corresponding side parts of the open frame body, in this example, at one side of a hinge body mounting surface 1 c. The axes of the two coaxial holes 3 pass through the accommodating notch 2.

The fixed connection device of the open frame body 1 comprises mounting holes 4 which are intersected with the axis of the coaxial line hole 3 or form an included angle of 90 degrees and are respectively arranged on the frame edges 1a at the two sides of the fixed connection device. When in installation, one of the hinged bodies, namely one face of the open frame body 1, which is close to the coaxial line hole 3, is closely attached to corresponding parts of equipment, such as a door frame or a door body, and the like, and the hinged body is fastened and connected to the corresponding parts of the equipment through corresponding fasteners, such as screws, and the like through the installation holes 4.

In this example, an arc-shaped groove 10 is provided on the side of the connecting frame edge 1b close to the mounting surface 1 c. When the arc-shaped groove 10 of the hinge device is matched with a corresponding protruding part arranged on the equipment using the hinge device, the auxiliary stable connection function of fixed installation can be achieved.

As shown in fig. 5-7. The other hinge body 5 of the two hinge bodies comprises a hinge arm 6, a fixed connecting part or a fixed connecting arm 7 fixedly connected to the other end of the hinge arm, and the like. The articulated arm 6 is arranged in relation to the fixed connecting arm 7 in a rectangular curved shape arched to the corresponding side of the fixed connecting arm.

The movable connecting device of the hinge device also comprises a hinge shaft hole 9 arranged at the free end of the hinge arm 6, a corresponding hinge pin shaft device and the like. The hinge pin device of the present embodiment includes a hinge pin 11 and the like having a smooth surface on the outer peripheral wall surface thereof.

The fixed connection means of the other articulation 5 comprise two corresponding mounting holes 8a provided in the fixed connection arm 7, stepless direction-changing adjustment means, etc. The stepless direction-changing adjusting device comprises a direction-changing composite hole 8b which is arranged on the fixed connecting arm 7 and is in a corresponding inclined state, wherein the direction-changing composite hole 8b comprises a kidney-shaped hole 8b1 and a diameter-expanding round hole 8b2 which is connected with one end of the kidney-shaped hole 8b 1. The inclination of the axis of the direction-changing composite hole or kidney-shaped hole 8b1 in the longitudinal direction with respect to the axis direction of the hinge shaft hole 9 of the other hinge body 5 is smaller than 90 degrees and larger than 0 degrees. The corresponding mounting holes 8a and the direction-changing composite holes 8b are distributed in a triangle shape.

The hinge arm 6 of the other hinge body 5 corresponds to the accommodating notch 2 of one hinge body, namely the open frame body 2, and one end of the hinge arm 6 is rotatably connected to the accommodating notch 2 of the open frame body 1 by passing through the two coaxial holes 3 of the open frame body 1 and the hinge shaft hole 9 of the hinge arm 6 through the hinge pin shaft 11. The two ends of the hinge pin 11 are in limit connection with the two hinge bodies by corresponding nuts and/or limit heads, and the limit connection mode and structure of the two ends of the hinge pin 11 can be similar to any similar connection structure and connection mode in the prior art.

A schematic structural view of an embodiment of the interconnection of two hinge bodies is shown in fig. 8. The connection mode is that when the other hinge body rotates to be completely extended out of the accommodating notch of one hinge body, the arch of the hinge arm is positioned on one side of the mounting surface of the open frame body. The wall surface of the hinge arm of the fixed connecting arm 7 of the hinge arm on the side of the bending opening of the bending shape forms a mounting surface, and is tightly matched with the corresponding wall surface of the equipment.

Mounting of the hinge device and the apparatus: the two hinge bodies are respectively and fixedly connected to two parts of the equipment, such as a door frame and a door body, which are movably connected with each other through corresponding screws and mounting holes thereof. When in specific installation connection, the open frame body hinge body can be installed firstly, the fixed connecting arm 7 of the other hinge body 5 is fixed on a corresponding part of the two-phase movably connected equipment through the corresponding installation hole 8a and the turning composite hole 8b respectively, the screw of the corresponding installation hole and the turning composite hole is connected firstly, then the installation position (or angle) of the other hinge body or the whole hinge device is adjusted through moving and adjusting the hinge device or the other hinge body according to the changed position of the turning composite hole and the screw thereof, so that the gap between the door body and the door frame of the equipment is minimum and parallel to a straight line, then the screw of the other corresponding installation hole is connected, and all screws are screwed, thus the connection installation of the door body and the door frame is completed. Typically one hinge is fixedly attached to a stationary part of the apparatus, such as a door frame, and the other hinge is fixedly attached to a movable part of the apparatus, such as a door body. However, according to the installation environment requirements such as the practical use situation, the two hinge bodies can also be mutually replaced and installed with the connecting component. The hinge device of the invention is similar to the basic installation connection principle of a hinge type hinge.
