Abstract

The utility model provides a movable bookshelf which is suitable to be used in the places, such as libraries and bookshops. The existing libraries and bookshops are restrained by the height of people, and the bookshelves can only be made into appropriate height, so the book storing amount is influenced. The utility model solves the problem; the book storing amount of the movable bookshelf is increased by 3-4 times compared with the existing bookshelves, and the books on the movable bookshelf can be selected freely.

Description

Movable book sheft

The utility model is a kind of bookshelf of the property improved, the bookshelf that particularly a kind of energy Enough increases the books in stock amount, and it is fit to, and library, bookstore etc. are local to be used.

Existing bookshelf is an open type.The height of bookshelf can not increase effectively because of being subjected to people's limitation in height, thereby has influenced the books in stock amount.In order to increase the books in stock amount, the quantity that library, bookstore can only take to increase its usable floor area and increase bookshelf reached in the past, and the height that can not increase bookshelf reaches.But little library, bookstore can not increase the quantity of bookshelf again owing to be subjected to the restriction of usable floor area, and that can only reduce the books in stock amount, because of being subjected to the influence of above-mentioned situation, have brought many adverse factors for library, bookstore, reader three parts.

In order to address the above problem, the utility model provides a kind of bookslide that can be manual or electronic.Purpose is neither need increase usable floor area, need not increase the quantity of bookshelf again.

Books in stock amount of the present utility model increases by 3～4 times than the books in stock amount of existing bookshelf, that is to say, little library, bookstore are become big library and bookstore.

Task of the present utility model is finished as follows: a kind of transmission device of mainly being made up of book bucket, chain, sprocket wheel, manual pulley, motor.When the reader need select other books and periodicals, can select for use manual or electronic.In the time of manually, reader's rotation manual wheel, chain is driven, when chain was driven, the book bucket was along with chain is made cycle rotation together, the reader just can rack for reading book on all books.Substantially with manually the same, different is to have loaded onto motor to electronic principle, reduces the link of manually-operated manual pulley.

The utility model can adopt the form of disperseing, concentrating according to actual conditions.Be exactly that a motor supplies a bookshelf so-called the dispersion, and so-called concentrating is exactly the shared motor of a plurality of bookshelves.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is wherein a kind of front view during the utility model is implemented.

Fig. 2 is the cutaway view of Fig. 1 bookshelf A-A line.

With reference to Fig. 1, Fig. 2, the utility model mainly is made up of book bucket (2), chain (6), manual pulley (5), shaft coupling (7), upper, middle and lower sprocket wheel (8), (10), (11).Its book bucket (2) is fixedly mounted on the chain (6) by shaft coupling (7).The book that book bucket (2) lining is adorned is selected for use for the reader, and the book bucket is installed quantity and decided according to actual conditions.Middle sprocket (10) and manual pulley (5) are installed on same the axle simultaneously, during rotation manual wheel (5), can drive middle sprocket (10) and rotate together.The ratchet of two subtends is equipped with in middle sprocket (10) the inside, and to prevent causing that owing to the distribution of weight of book is uneven chain (6) rotates voluntarily, influence is normally used.Lower sprocket (11) is made up of two sprocket wheels, and one of them is that the transmission of power supply motivation (9) is used, and another is used for chain (6) transmission, and the speed of motor (9) needs could use for this transmission device after slowing down.Upper sprocket wheel (8) plays the accessory drive effect in this transmission device.

During operation, can rotate manual pulley (5) up and down, in rotation manual wheel (5), middle sprocket (10) is also driven.At this moment chain (6) is made cycle rotation up and down with book bucket (2) under the drive of middle sprocket (10).Because book bucket (2) rotates up and down, make book bucket (2) in the bookshelf forward the outside of bookshelf one by one, at leisure to, the operator is selected in supply.If when selecting electric operating for use, that is as long as the operator presses last commentaries on classics button (3), and book bucket (2) just moves upward, and presses and changes button (4), and book bucket (2) just moves downward.

The utility model adopts metal material processing, and technological requirement is not high, is fit to medium-sized and small enterprises production.
