The present disclosure relates to a keyboard tray in the technical field of trays.
As an important external device of a computer, a keyboard generally needs to be placed in a certain space reserved on a desktop. However, the keyboard itself occupies a large area, and many users will use a keyboard tray to place the keyboard when the area on the desktop is limited.
Keyboard trays are classified into an integrated type and an assembled type. An integrated keyboard tray means that a movable keyboard tray is reserved on a computer desk itself, sliding rails capable of sliding out are mounted at the bottom of a desktop, a keyboard tray body slides out below the desktop through the sliding rails, and a keyboard will be placed on the keyboard tray body. An assembled keyboard tray means that a computer desk itself is not designed with a corresponding keyboard tray, and the keyboard tray is an additional structure which is assembled subsequently, and accordingly, the desk itself is not provided with bolt holes reserved for connecting to the keyboard tray. As such, an assembled keyboard tray on the market is generally fixed at the bottom of a desktop in a clamping mode, and sliding rails are also employed to slide out a keyboard tray body.
However, with increasing consumer demands for personalized adjustments, it is desirable to adjust a pitch angle of a keyboard according to the consumers' use habits, thereby reducing wrist discomfort during long-term use. Since the pitch adjustment range of the keyboard itself is limited, a keyboard angle adjusting function needs to be added to the keyboard tray. Although there are some keyboard trays including an angle adjusting mechanism on the market, the angle fixing mode thereof is based on fixing by tightening a knob, which is unstable, and may fail and lead to an angle change of the keyboard when a user presses the keyboard frequently. As such, the user has to adjust the angle frequently, which is quite troublesome.
An objective of the present disclosure is to solve one of the problems existing in the prior art, and the present disclosure provides a keyboard tray, which is allowed to adjust a pitch angle of a keyboard and lock the angle firmly to be difficult to be loosened.

With increasing consumer demands for personalized adjustments, it is desirable to adjust a pitch angle of a keyboard according to the consumers' use habits, thereby reducing wrist discomforts during long-term use. Since the pitch adjustment range of the keyboard itself is limited, a keyboard angle adjusting function needs to be added to the keyboard tray. Although there are some keyboard trays with an added angle adjusting mechanism on the market, the angle fixing mode thereof is based on fixing by tightening a knob, which is unstable, and may fail and lead to an angle change of the keyboard when a user presses the keyboard frequently. As such, the user has to adjust the angle frequently, which is quite troublesome.
Therefore, the present disclosure provides a keyboard tray, which adjusts a pitch angle of a supporting plate through an angle adjusting mechanisms, such that a turnover angle of a keyboard is changed to adapt to different angle requirements of a user; and by driving two positioning pins 330 through a pull rope 400, the position limiting can be canceled quickly, and the locking is stable and firm and difficult to be loosened.
