The sum of the lengths of the first baffle plate 8 and the second baffle plate 12 is equal to the distance between the first side plate 1 and the second side plate 2. The first notch 5 and the second notch 9 are symmetrically arranged, and the first baffle 8 and the second baffle 12 are the same in length. The upside of the rear end section of thick bamboo wall of matter storage lattice 4 is shorter than the downside, and is the arc transition. The clamping groove 13 is an inverted trapezoidal groove. The lower end of the elastic plate 21 is fixed on the first side plate 1 through a hinge shaft 31, and a torsion spring 32 for providing rotation to the elastic plate 21 in the direction of the first side plate 1 is arranged on the hinge shaft 31. The shape of elastic plate 21 is the U type, including preceding elastic strip 33 and back elastic strip 34, preceding protruding 22 of card is fixed in on the preceding elastic strip 33, back protruding 23 of card is fixed in on the back elastic strip 34. The first bending portion 26 is n-shaped, and when the first baffle 8 is located on the first notch 5, the top end of the first bending portion 26 is extruded on the rear elastic strip 34. The second bending portion 30 is L-shaped. The left side of first curb plate 1 with the right side of second curb plate 2 is sunken design, air pump 29 is two, is located respectively the left side of first curb plate 1 with the right side of second curb plate 2 the bottom of first curb plate 1 and second curb plate 2 is equipped with bottom plate 35 the top of first curb plate 1 and second curb plate 2 is equipped with roof 36.
In this embodiment, since the slot 13 is an inverted trapezoid-shaped groove, when the first baffle 8 and the second baffle 12 are respectively disposed in the first notch 5 and the second notch 9, the protrusion 14 is clamped in the slot, so as to increase the stability of the first baffle 8 and the second baffle 12, and ensure that the first baffle 8 and the second baffle 12 cannot be separated from the first notch 5 and the second notch 9 due to slight stress. However, when the first baffle 8 and the second baffle 12 are subjected to a large lateral force, the inverted trapezoidal groove design also facilitates the disengagement of the protrusion 14.
Because the base front side upwarp of first breach 5 and second breach 9 and the contained angle of horizontal direction is 20, in addition, the equal perpendicular to base of first rotatory jack 6 and the rotatory jack 10 of second, so design will make the front end of first baffle 8 and second baffle 12 also upwards perk and be 20 with the contained angle of horizontal plane, work as first baffle 8 and second baffle 12 certainly when deviating from in first breach 5 and the second breach 9, it can rotate to lattice 4 direction under the effect of gravity, realizes automatic closing cap lattice 4.
When the desk is used, the desktop 3 and the storage lattice 4 are in a vertical state under the action of gravity, the first baffle 8 and the second baffle 12 are also in a closed state, a reader firstly needs to open the first baffle 8 and the second baffle 12 and respectively rotate to the first notch 5 and the second notch 9, and due to the fact that the clamping groove 13 and the protrusion 14 act, the first baffle 8 and the second baffle 12 are stabilized on the first notch 5 and the second notch 9, the first baffle 8 and the second baffle 12 further play a role in separating adjacent reading tables, and interference between adjacent readers is avoided.
Then, the front end of the table top 3 is pulled by hand to rotate upwards, because the height of the storage compartment 4 is greater than that of the table top 3, and the design of the support rod 17, the roller 18 and the triangular convex plate 19, along with the upward rotation of the table top 3, the roller 18 can be gradually extruded on the triangular convex plate 4, and further the rear end of the storage compartment 4 is pushed to rotate upwards, when the support rod 17 is perpendicular to the triangular convex plate 19, the storage compartment 4 is raised to a high position, the rear slope structure 25 can stride over the rear clamping protrusion 23 from bottom to top, so that the storage compartment 4 is fixed to the high position, and at the moment, the lower side of the wall of the storage compartment 4 abuts against the arc-shaped plate 20, so that articles in the storage compartment 4 are prevented from sliding down. Because the number of the front clamping protrusions 22 is multiple, the inclination of the tabletop 3 can be adjusted, and the comfort of a user is enhanced.
Because the edge of preceding sloping structure 24 and back sloping structure 25 is the design of downward sloping, so be convenient for it cross preceding card protruding 22, back card protruding 23, and will desktop 3 with storage lattice 4 is fixed in the high-order, avoids its landing, has better stability. Since the storage compartment 4 is raised to the high position when the support rod 17 is perpendicular to the triangular protruding plate 19, the storage compartment 4 is not affected even if the tabletop 3 is raised again.
Because the lower end of the elastic plate 21 is fixed on the first side plate 1 through the hinge shaft 31, a torsion spring 32 for providing rotation to the elastic plate 21 in the direction of the first side plate 1 is arranged on the hinge shaft 31; the elastic plate 21 can be rotated around the hinge shaft 31, and the front elastic strip 33 and the rear elastic strip 34 move synchronously without applying other external forces. Namely: after the use of the present embodiment is completed, the first baffle 8 and the second baffle 12 are closed, the front locking protrusion 22 is manually pressed, so that the tabletop 3 can lose support and rotate downward, and along with the left movement of the front elastic strip 33, the rear elastic strip 34 can also move leftward, so as to drive the rear locking protrusion 23 to move leftward, so that the storage compartment 4 loses support and moves downward. However, when the first baffle 8 is located in the first notch 5, that is, the first baffle 8 and the second baffle 12 are in an open state, since the first bending portion 26 will abut against the rear elastic strip 34, with such a design, even if the front elastic strip 33 moves to the left, the rear elastic strip 34 will not move. It is further achieved that the user does not cause the storage compartments 4 to fall even if the user presses the front catching protrusion 22 to adjust the inclination of the table top 3. It is inherently required that the force pushing the first shutter 8 out of the card slot 13 is greater than the elastic force of the rear elastic strip 33.
Through above setting, after the user finishes using, need close first baffle 8 and second baffle 12, and then realize reaching desktop 3 and storage lattice 4 upset that falls simultaneously through pressing preceding card protruding 22, topple over article or books on it on the arc 20, and then avoid reader "overlook" the action at seat to appear, and supervise and urge the reader to form good reading custom.
The above actions are all based on the consciousness of the readers, and it is not excluded that some readers do not close the first baffle plate 8 and the second baffle plate 12 and press the front clamping convex 22 after the readers use the front clamping convex. The present embodiment further provides the technical means of the air pump 29, the first air bag 27 and the second air bag 28. A master switch is provided at the library manager to control all the reading tables and supply power to all the air pumps 29. After the library is closed, the library manager may supply power to the air pump 29, so as to inflate the first and second air bags 27 and 28, and the first air bag 27 pushes the front and rear elastic strips 33 and 34 to move left, so that the desktop 3 and the storage compartment 4 fall and turn over. In addition, the left movement of the elastic plate 21 also pushes the first bending portion 26 to move left and rotate, so that the first baffle 8 is disengaged from the first notch 5. Similarly, the inflation of the second bladder 28 will push the second flap 12 out of the second notch 9. This design has realized reading the automatic clearance of desktop "taking up a seat" article, has made things convenient for the library administrator, has improved cleaning efficiency to further supervise the reader to form good library reading order, stop the appearance of "dominating a seat" phenomenon.
To sum up, this embodiment has structural configuration reasonable, can effectively stop the advantage of "overlord seat" action, is suitable for extensive popularization and application.
