Easy to switch between landscape and portrait computer monitors

technical field

The utility model relates to a computer monitor, in particular to a computer monitor which is convenient for switching between horizontal and vertical screens.

Background technique

At present, most of the computer monitors are used horizontally. The horizontal screen can meet the general home and office usage habits. However, for professionals such as computer program developers, using the monitor vertically can improve the use efficiency. Most of the current vertical screen monitors use special vertical screen brackets, whose function is only to fix the monitor vertically and cannot switch to the horizontal screen state. Running the program on the horizontal screen display for testing can more intuitively reflect the running effect of the program in the state of ordinary people. If the vertical screen display cannot be switched to the horizontal screen state, the program can only be tested on the vertical screen display, or external A horizontal screen monitor is used for testing. Obviously, when testing a program on a vertical screen monitor, it is impossible to intuitively see the horizontal screen effect when the program is running. Therefore, most program developers currently choose to connect an external horizontal screen monitor to program the program. For testing, some developers even configure a separate computer with a horizontal screen monitor to test the program for the test program, which undoubtedly increases the configuration cost of the computer. In order to solve the above problems, those skilled in the art have designed computer monitor products that can switch between horizontal and vertical screens. A rotatable joint is set between the monitor bracket and the display screen assembly of this type of product, and the bracket is set to be able to be raised and lowered to prevent the problem. The display can be switched between horizontal and vertical screens. In order to satisfy the rotation of the display screen and the balance of the load bearing of the bracket, the rotary joint between the display screen assembly and the bracket needs to be set in the middle of the back of the display screen. For example, set buttons and latches on the joint to lock structure, when the user rotates the screen, he needs to reach out to the middle of the rear of the display screen. On the one hand, the distance is too far to reach directly, and on the other hand, the specific position of the locking structure cannot be seen by sight. The display with switchable horizontal and vertical screens on the market uses damping in the rotary joint to achieve the positioning of the display assembly. Although this positioning method is easy to operate, it only exerts resistance to the rotation of the display screen, and cannot completely prevent the display screen from rotating by itself after being subjected to force, especially the power supply and data wires behind the display are usually hard. The wires tend to pull on the display, making it difficult to hold the display in a fully vertical or fully horizontal position.
