[0035] Example 1

[0036] Reference Figure 1-Figure 5 , a modular digital display device for a keyboard, comprising a shell 1, a circuit board 8 is fixedly connected to the bottom inner wall of the shell 1, and a shaft 2 is fixedly connected to the bottom outer wall of the shell 1. The length of the shell 1 is the length of four keycaps of a general modular keyboard, and the width is the width of one keycap, so that it can be adapted to most keyboards and will not cause interference during the installation process. Pins are provided at the bottom of the shaft 2, and the pins use pins that are consistent with the pin position and length of the high axis. The keyboard only needs to have a universal keyboard high mechanical axis plug-in seat for connection, and a display screen 7 is provided on the outside of the top outer wall of the shell 1. The pins are electrically connected to the shaft 2, the circuit board 8, and the display screen 7, which can be applicable to most modular keyboards from different manufacturers and is easy to install. At the same time, the digital display device itself is equipped with a driving circuit board 8, so that the keyboard does not need to have a specific circuit and a specific matching structure. It has high adaptability and meets people's demand for using modular digital display devices.

[0037] In order to ensure the stability of the display screen 7 after installation, refer to Figure 4 A mounting base 12 is provided inside the housing 1, and the display screen 7 is fixedly mounted inside the mounting base 12, thereby ensuring the overall stability of the display screen 7 after installation.

[0038] Example 2

[0039] Reference Figure 1-Figure 5 , a modular digital display device for a keyboard. Compared with Example 1, this embodiment also includes circular holes on both sides of the outer wall of the shell 1, and a rotating shaft 5 is rotatably connected to the inside of the circular hole.

[0040] In order to facilitate people to quickly disassemble the digital display equipment and support the mobile phone, refer to Figure 1 The end of the rotating shaft 5 away from the inner wall of the shell 1 is fixedly connected to the pendulum rod 3. The cross section of the pendulum rod 3 is concave. When the pendulum rod 3 is rotated to an inclined or horizontal state, a certain storage space will be generated between the pendulum rod 3 and the shell 1. When people insert the mobile phone between the pendulum rod 3 and the shell 1 (in the storage space), it can provide good support for the mobile phone. At the same time, by adjusting the inclination angle of the pendulum rod 3, the tightness of the mobile phone fixation can be effectively adjusted.

[0041] In order to facilitate people to better pull the pendulum 3 upward, refer to Figure 1 An anti-slip groove 4 is provided on the outer wall of one side of the pendulum rod 3. The anti-slip groove 4 is distributed at equal distances on the outer wall of one side of the pendulum rod 3. The anti-slip groove 4 can increase the friction between the pendulum rod 3 and people's palms or fingers, making it easier for people to quickly disassemble the digital display device.

[0042] In order to ensure that the shaft 5 can rotate stably, refer to Figure 4 A thread groove 10 is provided at one end of the rotating shaft 5 close to the inner wall of the shell 1. The rotating shaft 5 is threadedly connected to a fixing nut 11 through the thread groove 10, which can limit one end of the rotating shaft 5 and ensure that the rotating shaft 5 can stably drive the rocker arm 3 to rotate together.

[0043] In order to ensure that the pendulum 3 can remain stable at any angle, refer to Figure 3 Figure 4 The outer wall of the circumference of the rotating shaft 5 is sleeved with a gasket 9, and the gaskets 9 are in contact with each other. The outer wall of one side of the fixing nut 11 is pressed tightly against the outer wall of one side of the gasket 9, which can generate a certain resistance during the rotation of the rotating shaft 5, thereby making the rotating shaft 5 have a self-locking function.

[0044] In order to avoid the swing rod 3 from rotating too much, refer to Figure 2 A baffle plate 6 is fixedly connected to the outer wall of one side of the shell 1. The two ends of the baffle plate 6 are vertically arranged. The baffle plate 6 can play a good limiting and blocking role on the rocker 3.

[0045] Working principle: When people use it in daily life, the pendulum rod 3 can be rotated to an inclined or horizontal state. At this time, the pendulum rod 3 will not block the display screen 7. At the same time, when the pendulum rod 3 is rotated to an inclined or horizontal state, a certain storage space will be generated between the pendulum rod 3 and the shell 1. When people insert the mobile phone between the pendulum rod 3 and the shell 1 (in the storage space), it can provide good support for the mobile phone. At the same time, by adjusting the inclination angle of the pendulum rod 3, the tightness of the mobile phone fixation can be effectively adjusted. At the same time, when people need to disassemble the digital display device, the pendulum rod 3 can be swung to a state perpendicular to the shell 1, and then only the pendulum rod 3 needs to be pulled upwards to achieve quick disassembly of the entire digital display device, and there will be no situation where the fingers pinch the outer wall of the shell 1 and slip and it is difficult to disassemble.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
