The utility model provides a kind of extension bookshelf, big for solving traditional bookshelf heaviness volume, when book is few
Book end is unstable, the problem of wasting space, and this patent is by state natural sciences fund（51169009）Support.
The technical solution of the utility model is：A kind of extension bookshelf, including framework, the root post of the frame sides four is
Aluminium-alloy pipe, the top board of framework, base plate and dividing plate are expansion plate 3, and strut 5 is provided between expansion plate 3；
The aluminium-alloy pipe includes big pipe 1 and tubule 2, is connected by pilot pin 4 between big pipe 1 and tubule 2；It is described flexible
Plate 3 includes outside plate and inner panel, is connected by pilot pin 4 between outside plate and inner panel.
Further, the pilot pin 4 is cylinder, and the outside of pilot pin 4 is provided with a fixing groove 9, the center longitudinal direction of pilot pin 4
A circular channel is provided with, spring 8 is fixed with passage, access portal one end is provided with steel ball 7.
Further, the big pipe 1 is provided with the hole for stationary balls 7, and tubule 2 is provided with pilot pin 4.
Further, the side of the big pipe 1 and tubule 2 is provided with groove.
Further, described inner panel one end is provided with pilot pin 4, and outside plate lower surface is provided with the hole for stationary balls 7.
Further, the strut 5 is fixed on the lower section of the outside plate of top board and base plate by articulated elements 6.
Further, the dividing plate is fixed on the lower end of big pipe 1.
The beneficial effects of the invention are as follows：Simple structure of the present invention, cost is relatively low, and storage is convenient, and generalization is strong, can be placed in
On desk, because its structure is scalable form, according to the amount adjustment width of books, and the position of book can be put vacantly it is placed in
Desktop top；Other articles can also be placed particularly below bookshelf, free space is increased.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1：As shown in Figure 1-2, a kind of extension bookshelf, including framework, the root post of the frame sides four is aluminium
Compo pipe, the top board of framework, base plate and dividing plate are expansion plate 3, and strut 5 is provided between expansion plate 3；
The aluminium-alloy pipe includes big pipe 1 and tubule 2, is connected by pilot pin 4 between big pipe 1 and tubule 2；It is described flexible
Plate 3 includes outside plate and inner panel, is connected by pilot pin 4 between outside plate and inner panel.
Embodiment 2：The present embodiment is identical with previous embodiment, wherein as shown in Figure 3-4, the pilot pin 4 is cylinder,
The outside of pilot pin 4 is provided with a fixing groove 9, and the center of pilot pin 4 is longitudinally provided with a circular channel, spring 8, passage are fixed with passage
Open at one end is provided with steel ball 7.
As shown in figure 5, the big pipe 1 is provided with the hole for stationary balls 7, tubule 2 is provided with pilot pin 4.Big pipe 1
Diameter is slightly larger than tubule 2, and tubule 2 can be packed into big pipe 1, and pilot pin 4 is fixed on the end of tubule 2, and big pipe 1 is provided with and compares steel ball
The bigger hole of 7 diameters, when big pipe 1 and tubule 2 are mutually slided, under the effect of spring 8, steel ball 7 is compressed in big pipe 1
Until running into the hole on big pipe 1, steel ball 7 is fixed big pipe 1 and tubule 2 by jacking hole.If shrinking big pipe 1 and tubule
2, steel ball 7 is withstood with hand, big pipe 1 and tubule 2 are mutually slided, after steel ball 7 is compressed, big pipe 1 and tubule 2 are retracted.
Embodiment 3：The present embodiment is identical with previous embodiment, wherein the side of the big pipe 1 and tubule 2 is provided with groove,
The mutual rotation due to big pipe 1 and tubule 2 is prevented prevent steel ball 7 and hole are from being correctly aligned.
Embodiment 4：The present embodiment is identical with previous embodiment, wherein described inner panel one end is provided with pilot pin 4, outside plate following table
Face is provided with the hole for stationary balls 7, prevents being mutually shifted due to the plate that the compressing of book makes steel ball be compressed and caused,
The quantity in cavity depends on the circumstances.
Embodiment 5：The present embodiment is identical with previous embodiment, wherein the strut 5 by articulated elements 6 be fixed on top board and
The lower section of the outside plate of base plate.Strut 5 is aluminum alloy materials, its role is to work as expansion plate 3 launches that more books can be put, due to
The weight of book is larger so that expansion plate 3 cannot bear up load, at this moment can just be supported with strut 5, and strut 5 is with articulated elements 6
Be connected to the lower section of outside plate, not the used time can pack up.The quantity of strut 5 depends on the circumstances, if expansion plate 3 is more long, or it is flexible
Plate 3 is more can to set several more.
Embodiment 6：The present embodiment is identical with previous embodiment, wherein the dividing plate is fixed on the lower end of big pipe 1, prevent due to
Expansion plate 3 stops when packing up aluminium-alloy pipe.
Specific embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not
It is limited to above-mentioned implementation method, in the ken that those of ordinary skill in the art possess, this practicality can also be not being departed from
Various changes can be made on the premise of new objective.
