The hinge device has a compact structure and can effectively save installation space, and the structural rigidity can be improved by hinged connection of the long swing arm 3 and the short swing arm 4, ensuring that it has sufficient load-bearing capacity and ensuring installation stability.

[0026] In this embodiment, one end of the long swing arm 3 and the short swing arm 4 connected to the fixed base 1 are both in a straight bar shape, and the other end are both in a hook shape. By setting the shape of the two swing arms to be hooked, the turning process of the flip seat 2 is not a simple circular motion trajectory, which can avoid the problem of the display screen 200 scratching the wall 300 during the turning process, and reduce the risk of damage to the display screen 200. During the turning process, the display screen 200 is pushed to turn, driving the flip seat 2 to move, and the flip seat 2 drives the long swing arm 3 and the short swing arm 4 to rotate and swing along the hinge point. Due to the limitation of the two swing arms, the flip seat 2 will not rotate in a perfect circle, so that the display screen 200 can be opened without scratching the wall 300, ensuring the safety of the display screen 200.

[0027] A rotatable first pin 5 is provided in the fixed base 1, and a first connection hole 31 is provided on the connection end between the long swing arm 3 and the fixed base 1. The first pin 5 passes through the first connection hole 31 and is limitedly connected with the long swing arm 3. The long swing arm 3 is limitedly hinged to the fixed base 1 by the rotatable first pin 5, which can ensure that the long swing arm 3 can be turned freely and can also be fixed in the fixed base 1 at the upper limit position, thereby improving the working stability.

[0028] A rotatable second pin 6 is provided in the flip seat 2, and a second connection hole 32 is provided on the connection end between the long swing arm 3 and the flip seat 2. The second pin 6 passes through the second connection hole 32 and is limitedly connected with the long swing arm 3. The long swing arm 3 and the flip seat 2 are limitedly hinged by the rotatable second pin 6, which can ensure that the long swing arm 3 can flip freely and can also be fixed in the limited position on the flip seat 2, thereby improving the working stability.

[0029] In order to limit the installation position of the long swing arm 3, a first slot 11 is provided at a position corresponding to the long swing arm 3 on the fixed base 1, and the long swing arm 3 is inserted into the first slot 11 and movably cooperates with the first slot 11. A second slot 21 is provided at a position corresponding to the long swing arm 3 on the flip seat 2, and the long swing arm 3 is inserted into the second slot 21 and movably cooperates with the second slot 21. In assembly, firstly, the two ends of the long swing arm 3 are respectively inserted into the first slot 11 and the second slot 21, and then the first pin 5 is inserted into the fixed base 1 and passed through the first connecting hole 31, so that the long swing arm 3 is installed and limited to the fixed base 1; then the second pin 6 is inserted into the flip seat 2 and passed through the second connecting hole 32, so that the long swing arm 3 is installed and limited to the flip seat 2. By providing the first slot 11 and the second slot 21, the position of the long swing arm 3 can be limited, so as to avoid displacement during flipping, and improve the stability of the structure.

[0030] A rotatable third pin 7 is provided in the fixed base 1, and a third connection hole 41 is provided on the connection end between the short swing arm 4 and the fixed base 1. The third pin 7 passes through the third connection hole 41 and is limitedly connected with the short swing arm 4. The short swing arm 4 is limitedly hinged to the fixed base 1 by the rotatable third pin 7, which can ensure that the short swing arm 4 can flip freely and can also be fixed in the fixed base 1 in the limited position, thereby improving the working stability.

[0031] A rotatable fourth pin 8 is provided in the flip seat 2, and a fourth connection hole 42 is provided on the connection end between the short swing arm 4 and the flip seat 2. The fourth pin 8 passes through the fourth connection hole 42 and is limitedly connected with the short swing arm 4. The short swing arm 4 is limitedly hinged to the flip seat 2 by the rotatable fourth pin 8, which can ensure that the short swing arm 4 can flip freely and can also be fixed in the limited position on the flip seat 2, thereby improving the working stability.

[0032] In this embodiment, there are two short swing arms 4, and the two short swing arms 4 are symmetrically arranged on the left and right side walls of the fixed base 1; by setting two short swing arms 4, the load-bearing capacity of the hinge device can be improved, and the stability of the structure can also be improved, ensuring that the display screen 200 can be opened smoothly.

[0033] In order to facilitate the connection between the display screen 200 and the hinge device, in this embodiment, a connection block 9 is provided on the flip seat 2, and the connection block 9 is fixedly connected to the flip seat 2 by screws. A pull plate 10 is provided on the connection block 9, and the center line of the pull plate 10 is perpendicular to the center line of the flip seat 2. During installation, the pull plate 10 is attached to the display screen 200, and then the pull plate 10 is connected and fixed to the display screen 200 by screws to connect and fix the display screen 200 to the hinge device; by providing the pull plate 10, the contact area between the hinge device and the display screen 200 can be increased, thereby ensuring that the display screen 200 and the hinge device are installed and fixed, preventing the display screen 200 from shifting or falling off, and improving the stability of the installation.

[0034] In this embodiment, there are two connecting blocks 9, and the overall shape of the connecting blocks 9 is "T"-shaped. By providing two connecting blocks 9, the pull plate 10 can be connected and fixed to the flip seat 2 to prevent loosening, thereby improving the stability of the structure; the "T"-shaped connecting block 9 allows the pull plate 10 to maintain a vertical state with the flip seat 2, which facilitates the installation and fixation of the display screen 200 and the pull plate 10.

[0035] When installing the hinge device, the fixed base 1 is connected and fixed to the bottom frame 100 of the display by screws, and then the pull plate 10 is connected and fixed to the display screen 200 of the display by screws, and the installation of the hinge device can be completed.

[0036] During use, by pushing the display screen 200 to flip, the pull plate 10 can be driven, and the pull plate 10 drives the connecting block 9 and the flip seat 2 to move synchronously, thereby driving the long swing arm 3 and the short swing arm 4 to rotate and swing along the hinge pin. Since the long swing arm 3 and the short swing arm 4 have different lengths, the pull plate 10 will not rotate along a perfect circle trajectory, which can effectively prevent the side of the display screen 200 from scratching the wall 300, thereby protecting the display screen 200.
