Description

Reversible desk with built-in bookshelf

technical field

The invention belongs to the technical field of teaching equipment, and relates to a desk device matched with a classroom, in particular to a reversible desk with a built-in bookshelf.

Background technique

As we all know, middle school students in China are under heavy academic pressure, and each student has a large number of books to store and arrange. Existing desk adopts two-layer arrangement structure mostly, is divided into two parts of desktop and table belly. When students place books, they can only stack the books one by one and put them in the belly of the desk, which does not make good use of the space of the entire desk. The storage space of the desks is too small, and there are too many books, resulting in an untidy learning environment. And when a student needs to use one of a large number of books, it often takes a long time to take out all the books, and then put the unnecessary books in. The structure of the desk itself is not convenient for the rapid removal and classification of books. , greatly reducing the efficiency of learning, these are problems that have been troubling students.

Contents of the invention

In order to solve the above problems, the present invention proposes a reversible desk with a built-in bookshelf that can increase the storage space, improve the efficiency of finding books, and make the learning environment more tidy.

Technical scheme of the present invention is as follows:

A reversible desk with a built-in bookshelf comprises a fixed desktop, a reversible desktop and a desk cavity.

The fixed desktop is installed on the supporting part through the first screw, and the supporting part is fixed on the front side wall outside the desk cavity through the first bolt.

The reversible desktop is connected with the steel frame structure of the desk cavity through hinges and second screws; the fixed circle is fixed with the reversible desktop through the third screw, and the fixed rod passes through the fixed circle and is fixed; one end of the wire rope Wrapped around the fixed rod, the other end goes around the pulley, and is connected with the bookshelf in the desk cavity through a wire rope chuck; the pulley is fixed to the side wall in the desk cavity by the second bolt; the guide rail is fixed in the desk cavity On the inner steel frame structure of the body, the movement track of the bookshelf is fixed by the guide rail; the elastic part is connected with the inner bottom plate of the desk desk cavity through the gasket and the fourth screw.

Its further technical solution is: the elastic component is a spring.

The beneficial technical effect of the present invention is:

In the present invention, the bookshelf is fixed under the desktop, and the steel wire rope wound on the pulley can be driven by turning over the desktop, so that the bookshelf moves up and down through the guide rails, which can not only solve the problem that students have too many books to place, but also solve the problem that the bookshelf stands on the table. Issues affecting teacher-student communication. Moreover, compared with the storage space in the usual desks, it is more convenient for book classification, which can greatly improve the learning efficiency of students and increase the cleanliness of the learning environment for students. The bottom of the desk cavity is equipped with an elastic device, which plays a buffer role when the bookshelf is lowered, and ensures the reliability of the bookshelf in the process of rising and falling. The invention has simple structure and convenient operation, and is especially suitable for being popularized and used in all primary and secondary schools.

detailed description

Fig. 1 is the left side view of the present invention, and Fig. 2 is the front view of the present invention, can see in Fig. 1 and Fig. 2: the novel desk comprises fixed desktop 1, reversible desktop 4 and desk cavity 19.

Fixed desktop 1 is installed on the supporting part 3 by screw 2, and screw 2 has 6 altogether, and model is M3 * 12 in the present embodiment, on the left side of fixed desktop 1, in the middle, two are respectively fixed on the right side. There is a protruding horizontal horizontal plate on the front side wall of the desk cavity 19, and the supporting part 3 is placed on the horizontal plate and fixed by bolts 16. There are 6 bolts 16 in total. In this embodiment, the model is M4×8. Fix two on the left, middle and right sides of the bottom of component 3.

The reversible desktop 4 is connected to the steel frame structure of the desk cavity through hinges 17 and screws 18; there are 2 hinges 17 and 4 screws 18. In this embodiment, the screw 18 model is M4×12. Every two screws 18 fix a hinge 17, and the hinge 17 makes the reversible desktop 4 can be lifted and turned backwards.

The fixed circle 7 is fixed with the reversible desktop 4 by the screw 5. There are 2 fixed circles 7, which are respectively fixed on the both sides of the reversible desktop 4. There are 4 screws 5, and every two screws 5 fix a fixed circle 7. In this embodiment, the model of the screw 5 is M6×30.

The fixed rod 6 passes through the fixed circle 7 and is fixed; one end of the wire rope 8 is wound around the fixed rod 6, and the other end is passed around the pulley 10, and is connected with the bookshelf 12 in the desk cavity 19 through the wire rope chuck 11; the pulley 10 is connected by a bolt 9 is fixed on the side wall in the desk cavity 19; There are four wire ropes 8, one is respectively fixed in the direction of the four corners of the bookshelf 12, and there are 6 pulleys 10, and there are three pulleys 10 on each side of the bookshelf 12, The two steel wire ropes 8 go around the first pulley 10 first, then the two steel wire ropes 8 separate, go around a pulley 10 respectively, and connect with the bookshelf 12 by the wire rope chuck 11. The structure of pulley 10 and steel wire rope 8 is left-right symmetrical on bookshelf 12 both sides. Each pulley 10 is fixed on the inside of the desk cavity 19 by a bolt 9, and in the present embodiment, the model of the bolt 9 is M6×30.

Guide rail 20 is fixed on the inboard steel frame structure of desk cavity, and guide rail 20 has 2, is installed in the left and right sides of desk cavity 19 inboards respectively, and bookshelf 12 is fixed its trajectory by guide rail 20. The elastic part 13 is connected with the inner bottom plate of the desk cavity 19 through the gasket 15 and the bolt 14. There are four elastic parts 13 in total, and each elastic part 13 is equipped with a gasket 15, which is respectively installed on the inner bottom plate of the desk cavity 19 Above, the positions corresponding to the 4 corners of the bookshelf 12 are used as buffer devices for the bookshelf 12. In this embodiment, the elastic member 13 is a spring.

Fig. 3 is the top view of this embodiment, it can be seen that the reversible desktop 4 is connected to the steel frame structure of the desk cavity 19 through the hinge 17, and the screw 5 fixes the fixed circle 7 on the reversible desktop 4.

In use, when the reversible desktop 4 is opened, the reversible desktop 4 drives the fixed circle 7, the fixed circle 7 drives the fixed rod 6, and the fixed rod 6 drives the steel wire rope 8 wound on the fixed rod 6 to move upward. The steel wire rope 8 goes around the pulley 10 to lift the bookshelf 12 upwards. The pulley 10 is a fixed pulley. Steel wire rope 8 all moves vertically upwards, guarantees that the process that bookshelf rises upwards is stable and safe. Students can place a large number of books orderly and neatly in the bookshelves 12, saving desk space and time for finding books, making the learning environment tidy and improving learning efficiency. When the reversible desktop 4 was closed, the bookshelf 12 moved downwards. When it reached the bottom, due to the existence of the elastic member 13, the bookshelf 12 was buffered from moving to stop, preventing the reversible desktop 4 and the desk cavity. Body 19 was injured by impact. After the reversible desktop 4 is closed, the fixed desktop 1 and the reversible desktop 4 are adjacently combined to form a plane, which together cover the desk cavity 19 as a large desktop, and students can use the large desktop for reading and writing.

The above descriptions are only preferred implementations of the present invention, and the present invention is not limited to the above examples. It can be understood that other improvements and changes directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
