Abstract

The utility model relates to a lifting bookshelf which comprises a plurality of layers. Each layer comprises a lower face plate (1), supporting regulating systems which are arranged at four corners and an upper face plate (5). Each supporting regulating system comprises a supporting rod outer cylinder (2), a rotational nut (3) and a supporting rod thread inner bar (4). The supporting rod outer cylinder (2) is a hollow round cylinder, and the bottom end of the supporting rod outer cylinder (2) is perpendicular to the lower face plate (1) and is fixed on the lower face plate (1). The rotational nut (3) is arranged on the top of the supporting rod outer cylinder (2). The supporting rod thread inner bar (4) is a solid round pole, the surface of the supporting rod thread inner bar (4) is provided with threads matched with the rotational nut (3), the upper end of the supporting rod thread inner bar (4) is perpendicular to the upper face plate (5) and is fixedly connected with the upper face plate (5), and the upper end of the supporting rod thread inner bar (4) penetrates through the rotational nut (3) and is inserted into a center hole of the supporting rod outer cylinder (2). The lifting bookshelf is simple in structure and simple and convenient to assemble, layer height is easy to adjust, and layers can be increased and the size can be expanded at any time.

Description

Lifting book shelf

Technical field

The utility model belongs to field of furniture, particularly relates to a kind of bookshelf.

background technology:

At present, known bookshelf consists of multilayer, and the interlamellar spacing between each layer is changeless, and books have different sizes and height, the unmatched situation of bookshelf and books is very general, little book is placed on wasting space on too high bookshelf layer, easily causes the idle of the many spaces of bookshelf, causes the wasting of resources; Professional storytelling in a local dialect is placed on too low bookshelf layer to tilt to put, and easily make the book bending, topple over, and every layer of books amount of putting also significantly reduces.In addition, because the number of plies of bookshelf is fixed, enable every layer height is regulated, also can't regulate lower bookshelf to total height and be increased a layer dilatation.

summary of the invention:

The deficiency that the utility model has overcome above-mentioned technology provide a kind of simple in structure, combine lifting book shelf easy, that regulate easily, can increase at any time layer dilatation.

Lifting book shelf of the present utility model, comprise lower panel, four jiaos of uniform support regulating system, top panels, wherein: support regulating system and comprise bar in support bar urceolus, rotary nut, support bar screw thread, the support bar urceolus is hollow cylinder, and bottom also fixedly mounts thereon perpendicular to lower panel; Rotary nut is placed on support bar urceolus top, and diameter of bore is slightly less than support bar urceolus diameter of bore; In the support bar screw thread, there is the screw thread coordinated with rotary nut on the bar surface, and its upper end is fixedly connected with top panel is vertical, and lower end is passed rotary nut and inserted in support bar urceolus centre bore.

Above-mentioned lifting book shelf, wherein: in the support bar screw thread, bar is solid pole .

Above-mentioned lifting book shelf, wherein: can form some layers by the said structure unit combination.

After the utility model has adopted such structure, can by easy instrument as required the number of plies carry out hand assembled, easy to assembly quick; Assemble and can independently control by the rotation rotary nut of four jiaos often highly layer by layer, adjustment is easy; After regulating, the bookshelf total height is starkly lower than design height, can continue, at the newly-increased layer of top layer, bookshelf is carried out to dilatation.

the accompanying drawing explanation:

Accompanying drawing is structural representation of the present utility model;

Mark in figure:

1, bar in lower panel 2, support bar urceolus 3, rotary nut 4. support bar screw threads

5, top panel

the specific embodiment:

Below in conjunction with accompanying drawing and preferred embodiment, the lifting book shelf specific embodiment, feature and effect thereof to according to the utility model proposes, be described in detail as follows.

As shown in Figure 1, lifting book shelf of the present utility model, comprise individual layer or some layers, and every layer comprises lower panel 1, four jiaos of uniform support regulating systems, top panel 5, the lower panel 1 of last layer can be the same panel with the top panel 5 of lower one deck, can be also that two-layer panel is superimposed together; Support regulating system and comprise bar 4 in support bar urceolus 2, rotary nut 3, support bar screw thread, support bar urceolus 2 is hollow cylinder, and bottom also fixedly mounts thereon perpendicular to lower panel 1; Rotary nut 3 is placed on support bar urceolus 2 tops, and diameter of bore is slightly less than support bar urceolus 2 diameter of bores; In the support bar screw thread, bar 4 is solid pole, and there is the screw thread coordinated with rotary nut 3 on surface, and its upper end is fixedly connected with top panel 5 is vertical, and lower end is passed rotary nut 3 and inserted in support bar urceolus 2 centre bores.

Panel of the present utility model can adopt the nut that is threaded, bores a hole to fix, rivet, weld or arrange the fixing modes such as patchhole with the connected mode of bar in support bar urceolus, support bar screw thread as required.

Operating procedure: the first step, each single part is combined as to lifting book shelf, each bookshelf need be that the number of plies adds one by panel quantity, need be number of plies quadruplication (every cover is containing respectively one of bar in support bar urceolus 2, rotary nut 3, support bar screw thread 4) by the support bar tricks; Second step, according to required size of putting books, the rotation rotary nut, to corresponding height, is convenient to pick and place freely a little more than books; The 3rd step: place the corresponding size books.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
