[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figure 1-6 As shown, an angle-adjustable reading rack includes a slide rail 1 fixedly mounted on a bookshelf and a rotating frame 2 movably mounted on the slide rail 1. A storage plate 3 for placing books is rotatably mounted on one end of the rotating frame 2. The rotating frame 2 is fixedly mounted with multiple sliders 10 for snapping onto the slide rail 1. There are two slide rails 1 and two sliders 10, respectively, and the sliders 10 are integrally formed with the rotating frame 2. Multiple reinforcing ribs 11 are fixedly mounted between the sliders 10 and the rotating frame 2 to further enhance the structural strength between the sliders 10 and the storage plate 3. The storage plate 3 is fixedly provided with two opposing adjustment plates 4. The rotating frame 2 is fixedly provided with two fixed plates 5 that abut against the outer sides of the adjustment plates 4. Each fixed plate 5 is provided with a locking pin 6 that extends through the fixed plate 5 and the adjustment plate 4. The end surface of each adjustment plate 4 facing away from the other adjustment plate 4 is provided with a circle of teeth 7. The end surface of the fixed plate 5 facing the adjustment plate 4 is provided with a plurality of protrusions 8 that engage with the protrusions 7. A pressure rod 9 is movably provided on each side of the storage plate 3 for pressing against the pages of a book or paper. In use, the storage plate 3 and the rotating frame 2 are pulled out along the slide rail 1, the storage plate 3 is removed from the slide rail 1, and the storage plate 3 is rotated to a desired angle. The storage plate 3 is then locked by tightening the locking pin 6 so that the protrusions 8 engage with the protrusions 7 on the adjustment plate 4. The circle of teeth 7 allows the storage plate 3 to have multiple adjustable angles, which can better accommodate children of different heights and provide more precise adjustment.

[0023] One end of the locking pin 6 is movably provided with a nut 12 through a threaded connection, and the end of the locking pin away from the nut 12 is fixedly provided with a knob 13, and the two fixing plates 5 are located between the knob 13 and the nut 12. The fixing plate 5 is provided with a fixing groove 14 for clamping the nut 12 at one end facing the nut 12. A limiting rod 15 is sleeved on the locking pin 6, and the limiting rod 15 is located between the two adjusting plates 4. The limiting rod 15 abuts between the two adjusting plates 4 to prevent the locking pin 6 from being tightened too much when locked, thereby causing deformation of the adjusting plates 4. The locking pin 6 can be easily rotated by the knob 13, and the nut 12 clamped in the clamping groove 16 prevents the nut 12 from rotating when the locking pin 6 rotates.

[0024] The storage plate 3 is provided with a slot 16 for engaging the pressure rod 9. The pressure rod 9 is L-shaped, and one end of the pressure rod 9 extending horizontally is pivotally mounted on the storage plate 3. The storage plate 3 is provided with a groove 17 surrounding the outer periphery of the slot 16. The width of the groove 17 is greater than the width of the slot 16, and the depth of the groove 17 is less than the depth of the slot 16. A recessed hole 18 is provided at the upper end of the slot 16, and a paddle 19 is fixedly mounted on the upper end of the pressure rod, located above the recessed hole 18. The storage plate 3 is provided with an anti-slip groove 20 for accommodating book spines to prevent slipping after the books are placed. The groove 17 and recessed hole 18 allow the pressure rod to be easily removed using the paddle 19.

[0025] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising from these variations or modifications to the specification remain within the scope of protection of this utility model.
