[0037] 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.

[0038] 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.

[0039] Referring to FIGS. 1 to 2, the keyboard tray according to an embodiment of the present disclosure comprises a fixing frame, a movable frame, angle adjusting mechanisms, a pull rope 400, and a supporting plate 500, wherein the fixing frame, the movable frame, and the supporting plate 500 form a main structure of the keyboard tray. The supporting plate 500 is used to directly support a keyboard, and a barrier strip 510 protruding outwards is mounted on the supporting plate, such that the keyboard can be prevented from sliding off the supporting plate 500 when the supporting plate 500 is turned over by a large angle. Specifically, the barrier strip 510 is an elastic piece, which reduces colliding with the user's wrist, and can also support the user's wrist, thereby improving the use experience. The fixing frame comprises a fixing frame body 110, and the fixing frame body 110 is fixed to the bottom of a desktop and provides supporting forces for other components. With regard to the fixing manner of the fixing frame body 110, fixed connection such as bolts, welding and the like may be adopted, and a detachable connection through clamping may be adopted as well. In this embodiment, the fixing frame further comprises clamping mechanisms 120, the quantity of the clamping mechanisms is at least two and the clamping mechanisms are all connected to the fixing frame body 110, and the fixing frame body 110 is fixed to the bottom of the desktop with the clamping mechanisms 120.

[0040] Specifically, each of the clamping mechanisms 120 comprises a clamping frame 121, a pushing screw rod 122, a pad 123, and a screwing handle 124, and the clamping frame 121 has a C shape and is clamped with a desktop edge. The clamping frame 121 is provided with a threaded hole for threaded connection with the pushing screw rod 122, and the pushing distance of the pushing screw rod 122 is adjusted by screwing the pushing screw rod 122. The pad 123 is mounted on a first end of the pushing screw rod 122, and the screwing handle 124 is fixed to a second end of the pushing screw rod 122 to facilitate holding by a user for screwing. The pad 123 is allowed to be driven close to the desktop and to clamp and fix the desktop together with the clamping frame 121 by screwing the pushing screw rod 122. The pad 123 is used to increase the contact area with the desktop and reduce the pressure on the desktop, thereby reducing damages to the desktop.

[0041] The movable frame comprises a movable frame body 210 and a sliding mechanism 220, a sliding rail in the sliding mechanism 220 is mounted on the fixing frame body 110, and a sliding block in the sliding mechanism 220 is connected to the movable frame body 210, such that the movable frame body 210 can be pulled out below the desktop to expose the keyboard carried by the movable frame body.

[0042] The quantity of the angle adjusting mechanisms is two and the two angle adjusting mechanisms are symmetrically arranged, and each of the angle adjusting mechanisms comprises a limiting plate 310, a supporting rod 320, and a positioning pin 330. The limiting plate 310 is connected to the movable frame body 210, the supporting rod 320 is hinged to the limiting plate 310, and the supporting plate 500 is fixed on the supporting rod 320, such that the supporting plate 500 can support the keyboard for turning over. A plurality of first limiting holes 311 are provided in the limiting plate 310, distances between each of the first limiting holes 311 and a hinge shaft of the supporting rod 320 are equal, and a second limiting hole is correspondingly provided in the supporting rod 320. When there is a need to lock the turnover angle of the supporting plate 500, the positioning pin 330 is passed through the first limiting hole 311 and the second limiting hole to achieve locking.

[0043] Both ends of the pull rope 400 are respectively hooked to ends of the two positioning pins 330, and the two positioning pins 330 are allowed to be simultaneously driven to withdraw from the first limiting hole 311 or the second limiting hole when a middle portion of the pull rope 400 is pulled by a user, such that unlocking is achieved, and the angle can be adjusted again at this time.

[0044] Further, the angle adjusting mechanism further comprises a reset member 340, both ends of the reset member 340 are respectively connected to the positioning pin 330 and the limiting plate 310, and the reset member is used to drive the positioning pin 330 to pass through the first limiting hole 311 and the second limiting hole. Therefore, after the positioning pin 330 is pulled out by the pull rope 400, and when the user releases the pull rope 400, the reset member 340 can automatically drive the positioning pin 330 to pass through the first limiting hole 311 and the second limiting hole so as to achieve locking again.
