Description

A kind of library sound absorption bookshelf

Technical field

Bookshelf is the utility model is related to, particularly a kind of library sound absorption bookshelf.

Background technology

Library be for reader read a book study place, it is necessary to peace and quiet, but hardly possible when reader consults books in library Exempt to have talk and browse the sound of books, noise can be produced, interference reader, which reads a book, to learn, and is presently used for the book in library Frame does not have sound absorption function, can not absorb caused noise in library, therefore, develops and provides a kind of library sound absorption book Frame, it is imperative to provide a peace and quiet, comfortable reading environment for reading public.

Utility model content

For the above situation, to overcome the defect of prior art, the purpose of the utility model is just to provide a kind of library With sound absorption bookshelf, can effectively solve the problem of absorbing caused noise in library, ensureing study and learning environment quiet.

The technical scheme that the utility model solves is including bookshelf, bookshelf be by from bottom to top it is multi-layer stacked together Forming, bookshelf is made an uproar device behind high 135-195cm equipped with suction, and described suction device of making an uproar is the U-shaped body being folded into by steel plate, It is U-shaped that sponge or glass wool material absorbent treatment are housed on face in vivo, aluminium sheet is housed in the front opening of U-shaped body, has hollow out on aluminium sheet Sound-absorbing hole, form sound absorption cavity configuration.

The utility model is simple in construction, novel and unique, and use easy to install, effect is good, efficiently solves making an uproar in library Sound absorbs problem, ensures quiet academic environment, there is good economic and social benefit.

Brief description of the drawings

Fig. 1 is structural perspective of the present utility model；

Fig. 2 inhales apparatus structure sectional view of making an uproar to be of the present utility model.

Embodiment

Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.

As shown in Figure 1, 2, including bookshelf 1, bookshelf 1 is made up of together from bottom to top multi-layer stacked, and bookshelf 1 is in height Made an uproar device 2 equipped with suction behind at 135-195cm, described suction device 2 of making an uproar is the U-shaped body being folded into by steel plate 3, it is U-shaped in vivo Sponge or glass wool material absorbent treatment 4 are housed on face, aluminium sheet 5 is housed in the front opening of U-shaped body, there is the suction of hollow out on aluminium sheet 5 Acoustic aperture 6, form sound absorption cavity configuration.

In order to ensure that using effect and working service are convenient,

Described bookshelf 1 is by first layer 1-1 from bottom to top, second layer 1-2, third layer 1-3, the 4th layer of 1-4, five Layer 1-5, layer 6 1-6 are stacked composition, 1 a height of 195cm of bookshelf.

Described suction makes an uproar device 2 behind the layer 5 of bookshelf 1, layer 6.

Described aluminium sheet 5 is installed on the front opening of U-shaped body, forms disassembly and assembly structure.

Described suction device 2 of making an uproar is fixed on the layer 5 of bookshelf 1, on the rear portion of layer 6 through dop or screw, and composition is torn open Assembling structure.

Described suction make an uproar device 2 length it is identical with the width of bookshelf 1, wall thickness 2cm, be highly 60cm, if necessary may be used It is divided into two layers, every layer of 30cm.

A diameter of 0.4mm of described sound-absorbing hole 6.

The utility model due to employing suction in structure in use, make an uproar device, noise is through the sound-absorbing hole on aluminium sheet, part Absorbed by sound-absorbing hole, partly by cavity absorption, form an effective sound absorption structure；When in library reader browse books or When person talks, it is contemplated that reader's height differences, sound absorption structure are arranged on the 5th, layer 6, effectively cover most sound sources Highly；The acoustically effective thus having had, effectively solve to the noise absorption in library, ensure the quiet ring of study and learning Border, there is good economic and social benefit.
