[0034] Example 1

[0035] like Figure 1-6As shown, this utility model provides an easily adjustable reading table, including a table body 1. A rotating groove 7 is provided on the upper surface of the table body 1. A placement plate 5 is provided inside the rotating groove 7. Rotating rods 9 are fixedly connected to the left and right sides of the placement plate 5 and are rotatably connected to the inner wall of the rotating groove 7 through bearings. An angle adjustment mechanism is provided inside the rotating groove 7. A stop plate 6 is fixedly connected to the front of the upper surface of the placement plate 5. Two sets of pressing mechanisms 8 are symmetrically arranged on the upper surface of the placement plate 5.

[0036] In this embodiment, the angle adjustment mechanism can adjust the reading angle of the placement plate 5 according to the user's needs, so that the user can adjust to a suitable reading angle for reading. The stop plate 6 can block the bottom of the book, and the pressing mechanism 8 can press the book placed on the placement plate 5 to prevent the book from closing. The user does not need to press it manually, which can free the user's hands to do other things.

[0037] Example 2

[0038] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution. Preferably, the pressing mechanism 8 includes two fixing blocks 81, both fixedly connected to the placement plate 5. A hollow plate 84 is provided between the two fixing blocks 81. Rotating rods 83, which are rotatably connected to the corresponding fixing blocks 81 via bearings, are fixedly connected to the front and rear sides of the hollow plate 84. Torsion springs 82 are sleeved on the surface of the rotating rods 83. A limiting plate 89 is slidably connected to the inner wall of the hollow plate 84. An elongation is fixedly connected to one side of the limiting plate 89. Plate 86, extension plate 86 penetrates hollow plate 84 and is slidably connected to the penetration part. A rubber cylinder 85 is fixedly connected to one side of extension plate 86. A pull frame 87 is fixedly connected to the upper end face of rubber cylinder 85. A positioning component 88 is provided on the upper end face of hollow plate 84. The positioning component 88 includes a threaded sleeve 882 that penetrates hollow plate 84 and is fixedly connected to the penetration part. An abutment screw 883 is threadedly connected inside the threaded sleeve 882. A cross-shaped rotating block 881 is fixedly connected to the upper end face of abutment screw 883.

[0039] In this embodiment, when the position of the rubber cylinder 85 needs to be adjusted, the cross-shaped rotating block 881 rotates the abutting screw 883, and the threaded sleeve 882 causes the abutting screw 883 to rotate upward, releasing the abutting effect on the extension plate 86. Then, the extension plate 86 is pulled directly to make the extension plate 86 drive the limiting plate 89 to slide inside the hollow plate 84, thereby adjusting the position of the rubber cylinder 85. After the adjustment is completed, the cross-shaped rotating block 881 is reversed to make the abutting screw 883 rotate downward, so that the abutting screw 883 abuts against the upper end face of the extension plate 86 to limit the extension plate 86, which is beneficial for pressing books of different widths. The rubber cylinder 85 can be pulled up by the pull frame 87 and rotated by the rotating rod 83. The side of the unfolded book is placed under the rubber cylinder 85. By releasing the pull frame 87, the rubber cylinder 85 rotates in the opposite direction under the action of the torsion spring 82, so that the rubber cylinder 85 presses on the book to press the unfolded book without the need for manual pressing by the user, which frees the user's hands to do other things.

[0040] Example 3

[0041] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution. Preferably, the angle adjustment mechanism includes a trapezoidal lead screw 13. One end of the trapezoidal lead screw 13 passes through the table body 1 and is rotatably connected to the through part via a bearing. One end of the trapezoidal lead screw 13 is fixedly connected to a rotating handle 3 that is rotatably connected to the inside of a rotating groove 4 on the front side of the table body 1. Limiting rods 11 are provided on both sides of the trapezoidal lead screw 13 and are fixedly connected to the inner wall of the rotating groove 7. A movable slide plate 12 is slidably connected to the inner wall of the rotating groove 7. The movable slide plate 12 is threaded onto the surface of the trapezoidal lead screw 13 and slidably fitted onto the surface of the limiting rods 11. Two hinge plates 10 are provided on the upper end surface of the movable slide plate 12 and are hingedly connected to the upper end surface of the movable slide plate 12. The upper end of the hinge plate 10 is hingedly connected to the lower end surface of the placement plate 5. Table legs 2 are fixedly connected to the four corners of the lower end surface of the table body 1.

[0042] In this embodiment, when the angle of use of the placement plate 5 needs to be adjusted, the trapezoidal screw 13 is rotated by rotating the handle 3. The rotation of the trapezoidal screw 13 causes the movable slide plate 12 to slide inside the rotating groove 7. The limiting rod 11 can improve the stability of the movable slide plate 12 during sliding. When the movable slide plate 12 slides, it can push the placement plate 5 under the action of the hinge plate 10, causing the placement plate 5 to rotate under the action of the rotating rod 9, thereby allowing the angle of use of the placement plate 5 to be adjusted.

[0043] The specific working principle and usage method of this utility model are as follows:

[0044] This utility model provides an easily adjustable reading table, such as Figure 1-6 As shown, during use, the user rotates the handle 3 to rotate the trapezoidal screw 13. The rotation of the trapezoidal screw 13 causes the movable slide plate 12 to slide inside the rotating groove 7. When the movable slide plate 12 slides, it pushes the placement plate 5 under the action of the hinge plate 10, causing the placement plate 5 to rotate under the action of the rotating rod 9. This allows the angle of use of the placement plate 5 to be adjusted, making it convenient for the user to use.

[0045] The user places the unfolded book on the placement plate 5, pulls up the rubber cylinder 85 by the pull frame 87, causing the rubber cylinder 85 to rotate under the action of the rotating rod 83, and then places the side of the unfolded book under the rubber cylinder 85. By releasing the pull frame 87, the rubber cylinder 85 rotates in the opposite direction under the action of the torsion spring 82, so that the rubber cylinder 85 presses on the book to press the unfolded book without the user having to press it manually, which frees the user's hands to do other things.

[0046] When the position of the rubber cylinder 85 needs to be adjusted, the abutment screw 883 is rotated by the cross-shaped rotating block 881. Under the action of the threaded sleeve 882, the abutment screw 883 is rotated upward, releasing the abutment effect on the extension plate 86. Then, the extension plate 86 is pulled directly, causing the extension plate 86 to slide inside the hollow plate 84, thereby adjusting the position of the rubber cylinder 85. After adjustment, reversing the cross-shaped rotating block 881 will cause the abutment screw 883 to rotate downward, so that the abutment screw 883 abuts against the upper end face of the extension plate 86, limiting the extension plate 86 and facilitating the pressing of books of different widths.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
