Description

adaptive bookshelf

technical field

The invention relates to the technical field of library hardware equipment, in particular to a bookshelf device.

Background technique

The bookshelf is an essential office tool in the library. In the library of the prior art, books are all fixed by iron or plastic bookends, but the bookends have a small clamping force, and there are not many books accommodated, and they are easy to tilt and crooked if they are placed too much, thereby increasing the The work intensity of the staff, and if the books are fixed by the bookend, if the height is about the same, it will be more troublesome, time-consuming and labor-intensive to take the book. And the bookshelf and the book end are separated from each other. When the book end is not in use, the book end needs to be put away. When in use, the book end is taken out again, which brings a great workload to the library administrators.

Contents of the invention

The technical problem to be solved by the present invention is to provide a self-adaptive bookshelf, which has a delicate structure, does not affect each other among books, and is easy to use.

The technical scheme adopted by the present invention is: provide an adaptive bookshelf, including the main frame of the bookshelf; the front and rear of the main frame are rectangular hollow frames; the left and right sides of the main frame are rectangular panels; the lower end of the main frame is a load-bearing plate; The upper surface of the load-bearing plate is evenly distributed with rubber convex strips; the upper end of the main frame is provided with an adaptive window; at least two horizontal shafts are installed in the adaptive window; the upper shaft of each horizontal shaft is connected with a row of vertical bars arranged in parallel ; Each vertical bar is connected to the horizontal shaft at the rear end; the lower surface of each vertical bar is concave arc surface.

To further optimize this technical solution, the rectangular panel of the self-adaptive bookshelf is composed of two half-body panels that are slid and plugged together in the length direction; the two half-body panels are locked by automatic buckles.

To further optimize the technical solution, the adaptive window of the self-adaptive bookshelf is covered with a dust-proof top cover.

To further optimize the technical solution, sockets are provided around the self-adaptive window of the self-adaptive bookshelf; pins that cooperate with the socket are provided around the lower surface of the load-bearing plate.

The beneficial effects of the present invention are:

1. The core structural principle of this technical solution is to prevent the paper at the bottom of the book from being scattered or slipped as a whole through the rubber convex strips at the bottom; the books are isolated from each other through the gravity drooping of the vertical bar, and certain clamping and gripping are provided on the left and right sides above the books support. The overall structure of the bookshelf is simple, and the vertical bars can be lifted up when the books are put in, and the vertical bars on both sides hang down naturally to support it. In addition, since the vertical bar of the book shelf changes from the vertical state to the horizontal state, the allowable height of books also has a large range, and books of different sizes and thicknesses can also be placed in the book shelf, so that books of the same kind but different sizes Books can be put together for convenience.

2. The length of the rectangular panel can be stretched and adjusted, so that books of different heights can be put in at the same time.

3. The self-adaptive bookshelf can be stacked and used in multiple vertical directions, and does not affect each other, only through the cooperation of the plug and the jack, and the combination is convenient.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1-3, the adaptive bookshelf includes a bookshelf main frame 1; the front and rear of the main frame 1 are rectangular hollow frames 2; the left and right sides of the main frame 1 are rectangular panels 3; the lower end of the main frame 1 is a load-bearing plate 4 ; The upper surface of the bearing plate 4 is evenly distributed with rubber convex strips 5; the upper end of the main frame 1 is provided with an adaptive window 6; three horizontal shafts 7 are installed in the adaptive window 6; There is a row of vertical bars 8 arranged in parallel; each vertical bar 8 is connected to the horizontal shaft 7 at the rear end; the lower surface of each vertical bar 8 is concave arc surface; the rectangular panel 3 is formed in the length direction by Two sections of half-body panels 9 that slide and plug together are formed; the two half-body panels 9 are locked by means of automatic buckles 10; the adaptive window 6 is covered with a dust-proof top cover 11; the adaptive window 6 is surrounded by plugs. Holes 12 ; the lower surface of the load bearing plate 4 is provided with a latch 13 that cooperates with the socket 12 .

In the present embodiment, under the initial state (not put into the state of books), all the hanging bars 8 are naturally drooping by gravity, and the distance between the lower end of the hanging bars 8 and the load-bearing plate 4 is the minimum book length, of course, The length of the rectangular panel 3 is adjustable, and the minimum book size is adjusted thereupon. In the same way, under the horizontal state of the vertical retaining bar 8, it is the maximum length of the book.

Present embodiment arranges three rows of vertical retaining strips 8, and its purpose is to shorten the length of vertical retaining strips 8, increase the clamping amount of the book top that puts in, prevent the paper on the inside of the book upper end from being scattered.

As shown in Figure 4, the cross-section of the vertical bar 8 is a concave arc surface 14, and the vertical bar 8 is obliquely placed on the paper on the back side of the upper end of the book, and the paper can be pressed down under the action of gravity, and the paper will be subjected to the force of gathering inwards. , which prevents the corners of the book from curling up.

It is possible to change the position of A slider 4 on the slide rail 3, so as to select surfaces with different friction coefficients, control other experimental data to remain unchanged, and change one of the single variables to obtain multiple sets of data, calculate the average value, and improve the accuracy of the experiment Or keep the coefficient of friction constant and increase or decrease the weight of the weight 11 on the B slide block 7 to change a single variable therein, obtain multiple sets of data, calculate the average value, and improve the accuracy of the experiment.
