Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] Desks are common teaching tools in classrooms, used by students to support textbooks for writing and reading. Most schools now have morning reading sessions. Since these sessions take place shortly after students wake up, some students tend to feel sleepy, especially in winter. To improve learning efficiency, students often stand to read. However, because the desk is fixed, students can only read while standing, holding the book in their hands. For heavier books, holding them for extended periods puts a lot of pressure on the arms, and making notes while reading is inconvenient. The inventor discovered that if part of the desk could be raised to support the book while the student is standing, students wouldn't need to hold the book while reading, and could still make simple notes and write.

[0024] First embodiment:

[0025] like Figures 1-3 As shown, the desk provided by this utility model includes: table legs 11, and table feet 12 at the lower ends of the table legs 11. The shapes of the table legs 11 and table feet 12 are as follows: Figure 1 As shown, the table legs 11 and table feet 12 are welded into an L-shape, and are fixed together by a horizontal square tube in the middle. The table feet 12 are also made of square tube and are hollow inside. One of the table feet 12 has a groove 111 on one side and several through holes 112 are equally spaced on the opposite side. A slide rod 15 is slidably placed inside the hollow interior. A threaded hole is opened on the side wall of the lower end of the slide rod 15, and a bolt 113 is installed in the threaded hole. At the same time, the bolt 113 is located in the groove 111 and passes through the slide rod 15. After further tightening the bolt 113 into the through hole 112 on the other side of the table leg 11, the nut at the end of the bolt 113 presses against the side wall of the table leg 11, thereby fixing the slide rod 15 inside the table leg 11. A metal washer is welded to the upper end of the slide rod 15. The first tabletop 13 is fixed to the metal washer by screws. On the other hand, a metal washer is also welded to the other table leg 11. The second tabletop 14 is fixed to the metal washer by screws. The first tabletop 13 and the second tabletop 14 are neatly aligned at the joint. Figure 3 As shown, in use, first tighten bolt 113 so that its end retracts from the through hole 112 on the side wall of table leg 11. At this time, bolt 113 releases its constraint on slide rod 15. After pushing bolt 113 upward, slide rod 15 slides upward within table leg 11. As slide rod 15 moves upward, the first tabletop 13, fixedly installed at the upper end of slide rod 15, moves upward. Finally, tighten bolt 113 again so that it enters the through hole 112 at the upper end of table leg 11 and is further tightened. At this time, bolt 113 again constrains the position of slide rod 15. The state of the desk at this time is as follows. Figure 1 As shown, students can place their books on the first desktop 13 to read after standing up.

[0026] By dividing the original single desktop into two parts and setting an adjustable height first desktop 13 to facilitate reading while standing, the first desktop 13 can support the book when raised, reducing the pressure of the book on the student's arm compared to the existing fixed desktop.

[0027] Second embodiment:

[0028] like Figures 1-2 As shown, the first desktop 13 and the second desktop 14 have a base plate 16 at their lower ends. The area enclosed by the base plate 16 and the side plates 18 at both ends is a book box, which is used to store textbooks, etc. The existing base plate 16 is horizontally set, so the existing desk book box space is a cuboid. The difference between this device and the existing desk is that the base plate 16 is set at an angle, such as... Figure 2 As shown, the cross-section of the internal space of the book box is trapezoidal.

[0029] By setting the tilted base plate 16, the tilt angle of the book placed on the base plate 16 can be changed. When students look down to find the textbook, their line of sight is directly facing the spine of the book, which allows them to find the textbook they need more accurately.

[0030] Third embodiment:

[0031] like Figure 1 As shown, a sliding plate 19 is welded to the upper end of the base plate 16. The sliding plate 19 is perpendicular to the base plate 16 and divides the book box space into several areas. The advantage of doing this is that it is convenient to organize books of different sizes. Larger books are placed in one book box area and smaller books are placed in another book box area. This not only improves the space utilization of the book box, but also makes it more convenient to find books.

[0032] Fourth embodiment:

[0033] like Figures 1-2 , Figure 4 As shown, the slide plate 19 is slidably connected to the base plate 16. A slider 191 is horizontally provided at the lower end of the slide plate 19. A groove 161 is provided at the upper edge of the base plate 16. The groove 161 is a strip groove that matches the slider 191 and has a certain length. Therefore, the slide plate 19 can slide on the base plate 16 to adjust the size ratio of the book box space.

[0034] Working principle: By dividing the original one-piece desktop into two parts and setting an adjustable height first desktop 13 to facilitate students reading while standing, compared with the existing fixed desktop, the first desktop 13 can support the book after being raised, reducing the pressure of the book on the student's arm.

[0035] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
