bookshelf table

technical field

The present invention relates to the field of mechanism design and analysis in mechanism science and mechanical manufacturing, specifically a bookshelf table.

Background technique

There are many bookshelves in the library, and there are so many desks and stools, which provide readers with an excellent learning environment. When readers find a book they like, they take it out from the bookshelf, put a mark on it, and then go to the place where the desks and stools are placed to study. After the end, put the book back to the original place; this kind of repetition is a bit troublesome, and it is easy to find the place where the book was placed after reading the book, or simply put the book where it is when you are lazy to read, and give it to the library management. The staff caused a lot of inconvenience. Therefore save the trouble of taking books and putting them back for the convenience of readers, and also for the convenience of library management, it is necessary to design a bookshelf table.

detailed description

The bookshelf table shown in Figures 1 to 4 includes a left vertical board 1 and a right vertical board 13, the left vertical board 1 is connected to the right vertical board 13 through at least one book board, the One side of the book board is provided with a horizontal book board 9, and the same position inside the left side vertical board 1 and the right side vertical board 13 is respectively provided with a mounting plate 3, and the mounting plate 3 passes through a plane linkage mechanism. A desk board placed on one side of the horizontal bookboard 9 is connected; the position corresponding to the mounting plate 3 on the outside of the left vertical board 1 or the right vertical board 13 is provided for driving the plane The rotating device for the rotation of the connecting rod mechanism; the inner middle and lower parts of the left vertical plate 1 and the right vertical plate 13 are respectively provided with a limit pin I7 at the position close to the horizontal book plate, and the left vertical plate 1 The position where the inner middle and upper part of the right vertical board 13 is away from the horizontal book board is respectively provided with a limit pin II2; The positions of the bookboards 13 are all provided with inner bookstops 4 . The bookshelf table designed by the present invention can be used with one layer of book boards, or two or more layers of book boards to provide more space for books; when the bookshelf table is used as a bookshelf, the desk The board is on the side of the horizontal book board, and is limited by the limit pin I; if the bookshelf table needs to be used as a desk, the desk board can be rotated by turning the rotating device and driving the plane linkage mechanism to rotate to It is located above the left vertical board and the right vertical board, and the upper limit position is limited by the limit pin II; in order to isolate the books placed on the mounting board and the book board, the two ends of the book board are close to the mounting board There is an inner book stop at the position, which not only protects the books, but also provides a movable space for the planar linkage mechanism.

Bookshelf table as shown in Figure 1 to Figure 4, the middle upper part of the inner side of described left vertical board 1 and described right vertical board 13 is provided with and puts bookboard 5, and described left vertical board 1 and described The lower part of the inner side of the right side vertical board 13 is provided with a lower bookboard 10; one side of the horizontal bookboard 9 of the upper bookboard 5 is placed with a desk board II 15, and the horizontal bookboard 9 of the lower bookboard 10 One side of the board is placed with a desk board I11. In the specific embodiment provided by the present invention, the used bookshelf table is a two-layer bookshelf table, and according to the structural characteristics of the two-layer bookshelf table, two desk boards are used to realize the functions of the bookshelf table.

As shown in Figures 1 to 4, the plane connecting rod structure is a plane double rocker mechanism, and the installation plate 3, the desk board I11, the active rod I19, and the driven rod II18 form a plane double rocker Rod mechanism I; the mounting plate 3, the desk board II15, the active rod III21, and the driven rod IV20 form a planar double rocker mechanism II, and a linkage is provided between the active rod I19 and the active rod III21 Rod 16. The mounting plate 3 is provided with pin shaft I34, pin shaft II33, pin shaft III32 and pin shaft IV31 connected with the plane double rocker mechanism; in order to ensure the consistency of each desk board during the movement process, each The four corners of a desk board are provided with hinge points for connection, the two ends of the same side of the desk board II15 are respectively provided with hinge points D14 and hinge points C17, and the two ends of the same side of the desk board I11 are respectively provided with hinge point B6 and hinge point A8; in the plane double rocker mechanism I, the two ends of the active rod I19 are connected with the hinge point A8 and the pin shaft I34, and the driven rod II18 Both ends are connected with the hinge point B6 and the pin shaft II33; in the planar double rocker mechanism II, the two ends of the active rod III21 are connected with the hinge point C17 and the pin The shaft III32, the two ends of the driven rod IV20 are connected with the hinge point D14 and the pin shaft IV31. The linkage rod 16 provided between the active rod I19 and the active rod III21 ensures that the desk board I and the desk board II move simultaneously. In order to make the linkage rod 16 move flexibly, the active rod I19 and the The active rod III21 is provided with a pin for connecting the linkage rod 16 .

As for the bookshelf table shown in FIGS. 1 to 5 , the rotating device is a rotating hand wheel 12 , and the rotating hand wheel 12 is connected to the pin shaft I34 on the mounting plate 3 through a connection key 22 . Using the rotating hand wheel as the loading and unloading device can not only save the use of horizontal space, but also because the rotating hand wheel is circular, there will be no inconvenience caused by hooking the reader's clothes; the rotating hand wheel is connected through the connecting key pin Ⅳ , when the hand wheel is turned, it can drive the pin shaft IV to rotate. Since the pin shaft IV is connected to the active rod I, the plane double rocker mechanism I rotates and drives the desk board I to switch positions; and because the plane double rocker mechanism I The linkage rod is connected with the plane double rocker mechanism II, so when the plane double rocker mechanism I rotates, the plane double rocker mechanism II will also rotate through the action of the linkage rod, and the desk board II and the desk board I are simultaneously switched to The same position, thereby meeting the requirements of different readers for the use of bookshelf tables.
