[0024] As Figures 1 to 5 shown, a keyboard tray structure of a medium-sized fire control host includes a cabinet body 1 and a keyboard tray 2. The cabinet body 1 is a common industrial computer cabinet 1 in the prior art, which has electrical components such as a display inside and is used in combination with a keyboard.

[0025] Among them, the end of the keyboard tray 2 is rotatably connected to the inner side of the cabinet body 1 so that the keyboard tray 2 can be flipped and stored in the cabinet body 1. When the keyboard needs to be used, the keyboard tray 2 is flipped to a flat state to facilitate the staff to operate the keyboard to control the fire control host.

[0026] Specifically, mounting brackets 11 are symmetrically arranged on both inner sides of the cabinet body 1. An activity hole 111 is provided on the mounting bracket 11 along the height direction. Rotation pins 21 are arranged at the rear ends of both sides of the keyboard tray 2. The rotation pins 21 are movably inserted into the activity holes 111, so that when the keyboard tray 2 is flipped and folded, the rotation pins 21 rotate in the activity holes 111 and move along the height direction. To be precise, the keyboard tray 2 rotates inside the cabinet body 1 through the rotation pins 21, and the activity holes 111 on the mounting bracket 11 are arranged along the height direction, enabling the keyboard tray 2 to move up and down to a certain extent. It should be understood that after the keyboard tray 2 is flipped, it moves downward, and the rear end surface of the keyboard tray 2 is supported by the bottom of the cabinet body 1.

[0027] In this embodiment, a limit pin 112 is arranged on the mounting bracket 11, and a limit portion 22 is arranged at the top of the rear end of the keyboard tray 2. The limit portion 22 is in an arc structure, so that when the keyboard tray 2 is in the flipped and opened state, the limit portion 22 abuts against the limit pin 112. In addition, a bracket 101 is arranged at the bottom of the cabinet body 1. The top surface of the bracket 101 is a horizontal structure. When the keyboard tray 2 is in the flipped and opened state, the bottom of the keyboard tray 2 abuts against the bracket 101. The limit pin 112 limits the flipping and opening angle of the keyboard tray 2 and the bracket 101 provides support for the keyboard tray 2, providing a certain supporting force for the keyboard tray 2.

[0028] In this embodiment, a keyboard limit member 3 is further included. A receiving groove 23 for placing the keyboard is provided on the surface of the keyboard tray 2. The keyboard limit member 3 is fixed in the receiving groove 23 by a bolt 4. To be precise, a first limit edge 24 is formed by bending the top of one side of the keyboard tray 2 towards the keyboard limit member 3, and a second limit edge 31 is formed by bending the top of the keyboard limit member 3 towards the first limit edge 24. It should be understood that the keyboard needs to be placed in the receiving groove 23 of the keyboard tray 2 for a long time. The keyboard is restricted in the receiving groove 23 by the first limit edge 24 and the second limit edge 31, so that the keyboard will not fall out when flipped and opened or stored. An adjustment hole 32 is arranged on the keyboard limit member 3 along the length direction of the receiving groove 23. The adjustment hole 32 is adapted to the bolt 4. After loosening the bolt 4, move the keyboard limit member 3 until the keyboard can be placed between the first limit edge 24 and the second limit edge 31, and then move the keyboard limit member 3 towards the keyboard and tighten the bolt 4, so that the keyboard cannot move in the receiving groove 23 after the bolt 4 is tightened.

[0029] In addition, the keyboard limit member 3 divides the receiving groove 23 into a keyboard receiving groove 23 and a mouse receiving groove 23. The keyboard receiving groove 23 can limit the movement of the keyboard, and the mouse can be directly placed in the mouse receiving groove 23 for operation.

[0030] In this embodiment, a handle 25 is arranged at the bottom of the keyboard tray 2, which is convenient for the staff to flip the keyboard tray 2 when opening or closing.
