Abstract

Disclosed is a spatially adjustable stationery box, which comprises a box bottom and an inner box. The side wall of the box bottom is fixed with a pin. Two rotating plates are crosswise hinged on the pin. One end of the rotating plates is provided with a sliding shaft. The side wall of the inner box is formed with a long slot that is provided with two troughs. The sliding shaft is clamped in the long slot. With the simple structure, the stationery box when not in use can contain the inner box, reducing the whole size, while the stationery box when in use allows the inner box to be pulled out, increasing the used space, in which the operation is simple and no external tools are required. When in use, two sliding shafts are clamped in the troughs under the action of gravity. The inner box is located and supported and then very steadily pulled out, preventing shaking due to unsteady support to influence the application of the stationery box.

Description

The adjustable writing case in a kind of space

Technical field:

The utility model relates to the writing case field, more specifically to the adjustable writing case of a kind of usage space.

Background technology:

Writing case is the use stationery of each student's indispensability, and existing writing case is varied, and shape and structure is different, but present writing case is in the majority with individual layer, its usage space is less, and purposes is single, and it is few but also be mixed in together not only to place the quantity of stationery, so the more multilayer writing case of the number of plies just occurred, it is made up of framework and box body, and framework is divided into several layers, all is provided with an inner box in each layer, when using the inner box of needs is pulled out, pushing in the time of obsolete.Such structure has increased placement space greatly, can place different stationery at different inner boxs, and the stationery classification of using is placed, and seeks easily.But such structure makes that the volume of whole writing case is very big, carries inconvenience very.

The utility model content:

The purpose of this utility model is genuine the deficiencies in the prior art part, provides a kind of space adjustable writing case, and it is simple in structure, volume is little, and spatial content is big, and is easy to carry.

Technology solution of the present utility model is as follows:

The adjustable writing case in a kind of space, comprise box at the bottom of, inner box, be fixed with bearing pin on the sidewall at the bottom of the box, two mutual cross-articulation of flap are on bearing pin, an end of described flap has slide-bar; Form elongated slot on the sidewall of described inner box, have two draw-in grooves on the elongated slot; Described slide-bar is connected in the elongated slot.

The adjustable writing case in described a kind of space, described draw-in groove have upwards arcwall face.

The adjustable writing case in described a kind of space is hinged with lid at the bottom of the box.

The adjustable writing case in described a kind of space, the plate section on the described flap between through hole and the slide-bar is 2/3rds of a whole flap length.

The adjustable writing case in described a kind of space forms fillet at the bottom of the described box.

The beneficial effects of the utility model are:

1, the adjustable writing case in a kind of space, comprise box at the bottom of, inner box, be fixed with bearing pin on the sidewall at the bottom of the box, two mutual cross-articulation of flap are on bearing pin, an end of described flap has slide-bar; Form elongated slot on the sidewall of described inner box, have two draw-in grooves on the elongated slot; Described slide-bar is connected in the elongated slot, and this writing case is simple in structure, inner box can be placed in the box body in the time of obsolete, whole volume is very little, in the time of use inner box is pulled out from box body, has increased the space of using, and simple to operate, need be by external tool.

Two slide-bars are stuck in the draw-in groove under the effect of gravity when 2, using, and inner box is positioned support, and are very stable after making inner box pull out, and can not produce the situation that waits the influence use of rocking because supporting unstable.

3, form fillet at the bottom of the described box, increased integral aesthetic property; Be hinged with lid at the bottom of the box, play protection and increase ornamental effect.
