Abstract

The utility model provides an expandable white board which is characterized in that the decorative strips arranged on the upper and the lower edges of the original white board (as shown in Mark 1 of Figure 1) are substituted by decorative strips (as shown in Mark 3 and Mark 5 of Figure 2)with sliding tracks, therefore, when the white board needs to be expanded, all you need to do for drawing a standby white board hidden behind the white board out to proceed with writing (as shown in Mark 2 of Figure 2) is to hold a left and a right decorative strips (as shown in Mark 4 of Figure 2) on the white board and pull the decorative strips towards the left and the right.

Description

Expandable blank

Technical field

The utility model relates to the office appliance field, specifically a kind of expandable blank.

Technical background

Along with continuous progress in science and technology, the development of society, people's work rhythm is also in continuous quickening, when exchange of information mutually, still needs the most basic media of communication one blank sometimes.But a lot of working environments always seem narrower and small, blank write at ordinary times not for a long time, as long as point blank just enough a little, like this can conserve space.When but temporary needs is write more information sometimes, can think that the area of blank is not enough, can write with feeling not have.The utility model designs in order to solve this situation.

Summary of the invention:

The purpose of this utility model is to provide a kind of expandable blank.

To achieve these goals, technical scheme of the present utility model is: the ornamental strip (as schematic diagram two signs 3,5) that the ornamental strip of the last lower edge of original blank (indicating 1 as schematic diagram one) is renamed as the band slide rail, when needs enlarge the blank area, as long as hold the left and right ornamental strip (indicating 4) on the blank as schematic diagram two, left, right pulling ornamental strip, will extract the standby blank of ensconcing the blank back out and proceed to write (indicating 2) as schematic diagram two.

Cause standby blank to come off in order to prevent that the standby blank of pull is excessive, we are provided with standby blank pull limit sliding chutes (indicating 8 as schematic diagram three) and standby blank pull position-limitting pin (as schematic diagram three signs 7) on last slide rail.For undue the rocking of standby blank that prevents to pull out, the utility model is designed to circular arc (indicating 9,10 as schematic diagram five) to the lower edge of standby blank, and allow the lower edge circular arc of standby blank in lower edge arc chute (indicating 5), slide as schematic diagram two, five, because the pull of standby blank is subjected to the restriction of blank upper hopper chute and chute position-limitting pin, make between blank and the standby blank section of having overlapping, and the active force of overlapping standby blank lower edge circular arc of this section and lower edge arc chute has played and can too not rock after the standby blank pull of control comes out.The arc chute of lower edge also is the place that blank is placed lettering pen and wiping board.

The technical problem that solves:

The blank that uses has only a writing surface now, and when a lot of contents need be write, will feel did not have the place to write once in a while.The blank of the utility model design has designed two standby blank writing surfaces again in the back of a conventional writing surface, can solve the not enough problem of blank writing surface.

Technical scheme:

Technical scheme of the present utility model is: the ornamental strip (as schematic diagram two signs 3,5) that the ornamental strip of the last lower edge of original blank (indicating 1 as schematic diagram one) is renamed as the band slide rail, when needs enlarge the blank area, as long as hold the left and right ornamental strip (indicating 4) on the blank as schematic diagram two, left, right pulling ornamental strip, will extract the standby blank of ensconcing the blank back out and proceed to write (indicating 2) as schematic diagram two.

Beneficial effect:

The utility model is compared with existing product, can when written contents is few, reduce the place that blank takies, in the time of more written contents, can extract standby blank out in the back of blank and write, can be owing to the blank write area influences working and learning inadequately.

The specific embodiment:

Concrete enforcement of the present utility model is: the ornamental strip (as schematic diagram two signs 3,5) that the ornamental strip of the last lower edge of original blank (indicating 1 as schematic diagram one) is renamed as the band slide rail, when needs enlarge the blank area, as long as hold the left and right ornamental strip (indicating 4) on the blank as schematic diagram two, left, right pulling ornamental strip, will extract the standby blank of ensconcing the blank back out and proceed to write (indicating 2) as schematic diagram two.

Description of drawings:

Schematic diagram one is the positive facial vision figure of expandable blank

Positive facial vision figure after schematic diagram two comes for the standby blank of expandable blank is drawn out

Schematic diagram three is the vertical view that gets on the right track of expandable blank

Schematic diagram four is the side view that gets on the right track of expandable blank

Schematic diagram five is the side view of the lower railway of expandable blank

1, conventional blank

2, standby blank

3, the last slide rail of blank

4, the handle of standby blank

5, the glidepath of blank

6, slide rail on the standby blank

7, slide rail pull position-limitting pin on the standby blank

8, slide rail pull limit sliding chutes on the standby blank

9,10, the side view of standby blank

Claims

1, expandable blank, it mainly comprises common blank and standby blank, it is characterized in that: standby blank places the back of common blank.

2, according to the described expandable blank of claim 1, it is characterized in that: standby blank can move on upper and lower chute and slide rail.

3, according to the described expandable blank of claim 1, it is characterized in that: going up slide rail has positioning runner and positioning sliding block, controls the position that pulls out of standby blank.

4, according to the described expandable blank of claim 1, it is characterized in that: the left and right sides ornamental strip of blank becomes the handle of standby blank.

5, according to the described expandable blank of claim 1, it is characterized in that: the lower edge of standby blank is done in the arc-shaped, places in the glidepath of circular arc.
