In use there are some inconvenient occasions in blackboard at present.For example in use write area can seem and uses not, but is limited to explanations, the purpose of giving lessons can not wipe the existing related content on the blackboard again, causes inconvenience, the impact explanation effect of giving lessons.
Summary of the invention
For the problems referred to above, the utility model provides a kind of blackboard of variable write area, and the usable floor area that it can increase blackboard has improved the efficient of the explanation of giving lessons.
Its technical scheme is such: it comprises the blackboard main body, it is characterized in that: the described blackboard main body back side is equipped with the portable plate that can move horizontally.
It is further characterized in that: the upper and lower end section at the described blackboard main body back side is provided with respectively the draw-in groove that along continuous straight runs extends; The upper and lower end section in described portable plate front is provided with respectively the card article that along continuous straight runs extends; Described card article is flush-mounted in the described draw-in groove.
It further is characterised in that: the upper and lower end section at the described blackboard main body back side is symmetrically arranged with respectively outer blend stop and the inner sealer that along continuous straight runs extends, and the spacing convave trough between described outer blend stop and the inner sealer consists of described draw-in groove; Described portable plate has two, and the card article of described two portable plates embeds two clamp bar slots at the described blackboard main body back side from the left and right direction of blackboard main body respectively; Described two portable plate areas equate; Described blackboard also comprises blank, green plate.
After adopting design of the present utility model, by each is pulled out since the left and right sides with left and right portable plate, can obviously increase blackboard about write the zone, thereby avoid on the blackboard main body inconvenience of writing between busy.Be particularly conducive to and write full content on the blackboard main body, but in the situation that these contents can not be wiped again, increase the usable floor area that write area can increase the use blackboard but pull out left and right portable plate, improve the effect of the explanation of giving lessons.
Description of drawings
Fig. 1 is the major part schematic diagram in blackboard of the present utility model front.
Fig. 2 is portable plate schematic diagram of the present utility model.
Fig. 3 is the major part schematic diagram at the blackboard of the present utility model back side.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Such as Fig. 1, Fig. 2, shown in Figure 3, the blackboard that the utility model is selected is blank, comprise blank main body 1, left side portable plate 4, right side portable plate 5, blank main body 1 back side upper, the bottom is symmetrically arranged with respectively the outer blend stop 8 that along continuous straight runs extends, 11 and inner sealer 9,10, spacing convave trough between spacing convave trough between outer blend stop 8 and the inner sealer 9 and outer blend stop 11 and the inner sealer 10 consists of respectively draw-in groove 12,13, left side portable plate 4, the front of right side portable plate 5 upper, the bottom is provided with respectively portable plate upper end, the card article left side card article 2 that along continuous straight runs extends, right side portable plate upper end card article 3 and portable plate lower end, left side card article 6, portable plate lower end, right side card article 7, left side portable plate 4, the upper end card article 2 of right side portable plate 5,3 and lower end card article 6,7 respectively from the left side of blank main body 1, right embeds two clamp bar slots 12 at described blank main body 1 back side, in 13.
After adopting design of the present utility model, writing in the enough situations in zone above the blank main body 1 at ordinary times can be hidden in left side portable plate 4 and right side portable plate 5 back side of blank main body 1.If the zone of writing above the blank main body 1 needs to increase in the situation of extra write area not, can hold left side portable plate 4 so that card article 2 is along the outer blend stop 8 at the blank main body back side and the draw-in groove 12 of inner sealer 9 formation on the portable plate of left side, portable plate lower end, left side card article 6 is pulled out to the left along the inner sealer 10 at the blank main body back side and the draw-in groove 13 of outer blend stop 11 formation.When not needing to increase extra write area, can hold left side portable plate 4 so that the draw-in groove 12 that left side portable plate upper end card article 2 forms along outer blend stop 8 and the inner sealer 9 at the blank main body back side, the draw-in groove 13 that portable plate lower end, left side card article 6 forms along inner sealer 10 and the outer blend stop 11 at the blank main body back side pushes the back side of blank main body 1 to the right.Use right side portable plate 5 to operate equally.The portable plate lower end is provided with the design on lower edge can place writing pen, can be used for accepting chalk dust when selecting the blackboard material to be green plate, has avoided the direct pollution to office space.
