Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution: a keyboard tray that is easy to adjust, including a fixed frame 1, a clip 2 fixedly connected to the top of the fixed frame 1, a locking bolt 3 screwed onto the top wall of the clip 2, a slide plate 4 slidably connected inside the fixed frame 1, a baffle 5 fixedly connected to the end of the slide plate 4 away from the fixed frame 1, a placement frame 6 hinged to the side wall of the baffle 5 near the fixed frame 1, a placement groove 7 provided on the top wall of the placement frame 6, an adjustment component installed between the end of the placement frame 6 away from the baffle 5 and the slide plate 4, and the clip 2 having a U-shaped structure.

[0025] In practice, when using the device, first place a pair of clips 2 on the edge of the desktop and make the top surface of the fixing bracket 1 fit against the lower wall of the desktop. Rotate the locking bolt 3 to make its bottom press against the desktop to complete the installation of the device. Then place the keyboard in the placement slot 7 and push the slide plate 4, which is slidably connected to the inner side wall of the fixing bracket 1, to the appropriate position to adjust the horizontal position of the placement bracket 6.

[0026] See Figure 3 and Figure 4The adjustment assembly includes a slide rod 11, which is fixedly installed on the top surface of the slide plate 4. A slider 13 is slidably connected to the slide rod 11. A threaded seat 10 is slidably provided on the top surface of the slide plate 4. A connecting rod 12 is hinged to the side wall of the slider 13. The other end of the connecting rod 12 is hinged to the top surface of the threaded seat 10. A threaded screw 8 is rotatably connected to the side wall of the baffle 5 near the side wall of the slide plate 4. A first fixing plate 9 is fixedly connected to the top surface of the slide plate 4. The end of the threaded screw 8 away from the baffle 5 is rotatably installed on the side wall of the first fixing plate 9. The threaded screw 8 is threadedly connected to the threaded seat 10.

[0027] When it is necessary to adjust the tilt angle of the keyboard, turn the knob 20 to drive the threaded screw 8 to rotate. The threaded seat 10 is threadedly engaged with the threaded screw 8, so that the threaded seat 10 moves along the threaded screw 8, which in turn drives one end of the connecting rod 12 to move. The connecting rod 12 drives the slider 13, which is hinged to it, to move, so that the slider 13 slides along the slide rod 11, pushing one end of the placement bracket 6 to move in the vertical direction, thus completing the angle adjustment.

[0028] See Figure 3 There are two adjustment components, which are symmetrically installed on the top surface of the slide plate 4. A guide rod 14 is fixedly connected to the side wall of the baffle 5 near the slide plate 4. A second fixing plate 15 is fixedly connected to the top surface of the slide plate 4. The end of the guide rod 14 away from the baffle 5 is fixedly installed on the side wall of the second fixing plate 15. A moving block 16 is slidably connected to the guide rod 14. The end of the connecting rod 12 in the adjustment component away from the slider 13 is hinged to the top surface of the moving block 16. A connecting plate 17 is fixedly connected between the threaded seat 10 and the moving block 16.

[0029] With its symmetrical design, the placement rack 6 maintains a stable center of gravity when adjusting its angle, effectively preventing swaying or tipping caused by uneven force. This significantly improves the overall structural stability and safety during use. At the same time, it ensures a uniform distribution of support force under the placement rack 6, avoiding excessive pressure on a single point or local area. This not only reduces material fatigue and wear caused by stress concentration, but also extends the service life of the placement rack 6 and its adjustment components.

[0030] See Figure 2 and Figure 5A clamping plate 18 is slidably installed in the placement slot 7. A positioning spring 19 is installed between the clamping plate 18 and the inner wall of the placement slot 7. After the keyboard is placed in the placement slot 7, the positioning spring 19 provides appropriate pressure to the clamping plate 18, so that the keyboard is firmly fixed and avoids the keyboard sliding due to accidental touch or vibration during use. At the same time, this pressure adjustment method makes it very easy to fix and release the keyboard. Users can easily adjust the position of the keyboard or replace it as needed. A pull-out plate 21 is fixedly connected to the outer wall of the baffle 5 away from the fixing frame 1. The top surface of the pull-out plate 21 has an arc-shaped groove for users to place their wrists, which improves the comfort of users. The bottom surface of the pull-out plate 21 has a groove. Users can push and pull the slide plate 4 by inserting their fingers into the groove, thereby adjusting the horizontal position of the placement frame 6.

[0031] Working principle:

[0032] When in use, first place a pair of clips 2 on the edge of the desktop and make the top surface of the fixing bracket 1 fit against the lower wall of the desktop. Rotate the locking bolt 3 to make its bottom press against the desktop to complete the installation of the device. Then place the keyboard in the placement slot 7 and make the positioning spring 19 provide pressure to the clamp 18 so that the clamp 18 cooperates with the placement slot 7 to fix the keyboard. Then push the slide plate 4, which is slidably connected to the inner side wall of the fixing bracket 1, to the appropriate position to adjust the horizontal position of the placement bracket 6.

[0033] When it is necessary to adjust the tilt angle of the keyboard, turn the knob 20 to drive the threaded screw 8 to rotate. The threaded seat 10 is threadedly engaged with the threaded screw 8, so that the threaded seat 10 moves along the threaded screw 8, which in turn drives one end of the connecting rod 12 to move. The connecting rod 12 drives the slider 13, which is hinged to it, to move, so that the slider 13 slides along the slide rod 11, pushing one end of the placement bracket 6 to move in the vertical direction, thus completing the angle adjustment.
