detailed description

The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

As shown in Figures 1-5, a foldable small bookshelf for classrooms includes a bookshelf board 3, the bookshelf board 3 is connected with a bookstop 2, and a gap between the bookshelf board 3 and the bookstop 2 To form an accommodating space, sliding holes 4 are provided on both sides of the bookshelf board 3, and the sliding holes 4 are rectangular holes; a number of bookboards 5 are arranged between the bookshelf board 3 and the bookstop 2, so that One end of the book-setting board 5 is suspended from the sliding hole 4, and the other end of the book-setting board 5 is arranged on the book stop 2. One end of the sliding hole 4 slides to the other end; the book-setting board 5 is arranged between the bookshelf board 3 and the book-stop 2 in an inclined manner, and the book-setting board 5 and the book-stop 2 preferably form an angle of 40 degrees. The book shelf can be used for students to use in the classroom, and books are placed on the book board 5, because the books form an inclination angle with the vertical direction, occupy a small horizontal area, make full use of the limited space, and have a large number of books that can be accommodated.

It should be noted that the sides of the bookshelf board 3 are sequentially arranged in the structure of the first groove 8 and the first bump 9, and the sides of the bookend 2 are sequentially arranged in the structure of the second bump 10 and the second concave. The structure of the groove 11 is set. When folding, the first groove 8 matches the second protrusion 10, and the second groove 11 cooperates with the first protrusion 9; the bookend 2 is provided with a connecting long plate 12. The connecting long board 12 is provided with Velcro 6, and the setting of the connecting long board 12 and Velcro 6 is convenient for fixing the position of the bookshelf during use. Rule moves.

It is further explained that, the upper end of the bookend 2 is provided with a semicircular groove 13, and the upper end of the bookshelf is provided with a rotating handle 1. When the rotating handle 1 is not in use, the rotating handle 1 can be fixedly placed on the semicircular groove. On the groove 13, the setting of the handle facilitates the lifting of the bookshelf; the bookshelf board 3 and the lower end of the bookstop 2 are connected with aircraft wheels 7 to facilitate the movement of the bookshelf. The structural setting not only saves materials but also reduces the weight of the bookshelf, making it easy to carry.

Specifically, as shown in Figure 1-5, a kind of collapsible small bookshelf for classrooms is made of two square bookshelf boards 3 and bookend boards 2 with a height of 70 centimeters and a width of 28 centimeters before and after. There are three bookends 5 connected by hinges between the bookends 2, a rotating handle is connected to the top of the front square bookshelf board 3, four aircraft wheels 7 are connected to the bottom, and a long handle is connected to the back of the bookend 2. Two Velcro fasteners 6 are arranged on the board 12 .

It should be noted that the front square bookshelf board 3 has three rectangular holes on its left and right vertical support rods, so that one of the shafts of the book board 5 can slide up and down. 5 forms a 40-degree angle with the vertical side; the rear square bookend 2 has two semicircular grooves 13 with two bumps on its top; the two ends of the rotating handle 1 connected to the upper end of the bookshelf board 3 are welded There are two flat rods, the ends of the rods are connected with the top of the front square bookshelf board 3 by screws, and the rotating handle 1 can rotate around the central axis of the screws; the bottom of the bookshelf is connected with four aircraft wheels 7, two of which are connected with The bottom of the front square bookshelf board 3 is connected, and the other two are connected with the bottom of the rear square bookend 2; For the gap between the long board and the rear square bookend 2, the two nylon fasteners 6 can slide up and down in the gap.

A small foldable classroom bookshelf of the present invention, as shown in Figure 4, when it is in the folded state, rotate the rotating handle clockwise around the axis, and the flat rod ends at both ends of the handle will withstand the rear square bookend 2 , so that the gap between the front and rear square bookends 2 becomes larger. Books etc. are placed on the book board 5 this moment, and the cover or the back side of the book is close to the book board 5 facing upwards. Under the action of the gravity of the book, and there are freely slidable aircraft wheels 7 at the bottom of the bookshelf, the book board 5 will rotate around a relatively low axis, so that the bookshelf is further expanded, that is, the distance between the front and rear square bookends 2 increases until The relatively high axis of the book board 5 is limited by the oblong hole of the front square bookshelf board 3 . The bookshelf can be bound with the desk legs by nylon, as shown in Figure 3. When the bookshelf is fully unfolded, the rotating handle 1 can be stuck in the two semicircular grooves 13 on the top of the rear square bookend 2, and a person can hold the rotating handle to push the bookshelf to slide horizontally. If the bookshelf is to be folded, the books are first moved out of the bookboard 5, and the folding process is in the reverse order of the unfolding process.

For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and ideas described above, and all these changes and modifications should fall within the protection scope of the claims of the present invention.
