A kind of Extensible book-shelf is made up of two support bodys, and its characteristics are, described support body bottom and support are provided with pulley, this support is overlapped in the groove of support of another support body mutually, and pulley can slide in groove, is convenient to enlarge or reduce the capacity of bookshelf.

Described groove is arranged in the support of another support body, and its length is 4/5ths of this stent length; Adaptive mutually between the support of described two support bodys, and be set to 4 supports.

The beneficial effects of the utility model are, can increase or reduce and enlarge or reduce the capacity of storage book along with books, enlarge or dwindle its storage book capacity, and are easy to use, simple in structure, are suitable for various rooms and use.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of a kind of Extensible book-shelf of the utility model.

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, a kind of Extensible book-shelf, form by two support bodys, be respectively arranged with pulley 3 on one support body, 1 bottom and the support 4, the pulley 3 of this support 4 adopts plastic material to make, and the pulley of this support body bottom is provided with 2 at least, be fixed on the both sides of support body 1 bottom respectively by pulley 3 bearings, during slip, can not contact, can be convenient to this support body 1 and move with support body 1; The support 4 of this support body 1 is overlapped in the groove 6 of support 5 of another support body 2 mutually, and pulley 3 can slide in groove 6, is convenient to enlarge or reduce the capacity of bookshelf.The length of groove 6 is adaptive mutually between the support of support 5 length 4/5ths, two support bodys of another support body 2, the bookshelf that 4 supports of two support bodys cooperatively interact and constitute, the book weight that can bear its capacity.

During use, how much change the capacity of this bookshelf, when increasing storage book capacity, only need the support body 1 of pulling band pulley 3, just drive the pulley 3 of this support body 1 bottom, thereby enlarged the capacity of the storage book of this bookshelf according to books; When the books of placing reduce, promote the support body 1 of band pulley 3, thereby move inward, dwindled the capacity of the storage book of this bookshelf.Then the utility model has been finished with books and has been stored the task what change capacity, conveniently is used in various rooms.
