Abstract
The utility model discloses a chalk box. The chalk box comprises a box body opened at the upper end, wherein a top cover is arranged at the top of the box body; a supporting plate is glidingly mounted in the box body; a lifting lever is rotationally mounted on a left side plate and a right side plate of the box body below the supporting plate and adopts a shaft lever with an elliptic cross section; the right end of the lifting lever extends out of the box body, and a torsion handle is mounted at the right end of the lifting lever; the outer wall of lifting lever is contacted with the lower end surface of the supporting plate; a partition board is arranged on the inner walls of a front side plate and a rear side plate of the box body above the supporting plate and divides the box body into a left cavity body and a right cavity body; and suction cups are mounted in the corners of the outer wall of the left side plate of the box body and the lower end surface of a bottom plate respectively. The chalk box is novel in structural design, the lifting lever mounted in the box body and the supporting plate are matched, so that chalks in the chalk box can be taken out conveniently and rapidly, and the chalks in different colors can be placed in the left cavity body and the right cavity body of the box body; and besides, the suction cups are mounted on the box body, so that the chalk box can be conveniently fixed in the required position, the box body further can be utilized repeatedly, and accordingly, a large number of costs are saved.
Description
technical field:
The utility model relates to the chalk packing box, relates in particular to a kind of chalk holder.
background technology:
Chalk is the instrument widely used in daily life, is generally used for book and writes on the blackboard.The chalk in ancient times is made with natural chalk usually, but multiplex other material replaces now.The composition of chalk is a kind of white depositions of calcium sulfate, is not easy to be decomposed, and particle is larger than dust.Now, the chalk of domestic use mainly contains two kinds of common chalk and dust-free chalks, and its main component is calcium carbonate (lime stone) and calcium sulfate (gypsum), or containing a small amount of calcium oxide.
In classroom, teachers often are placed on the box of the papery that chalk is housed on dais, because the chalk holder of papery easily damages, cause chalk to become scattered about on lectern or, on floor, cause the classroom environment pollution.Certainly the chalk of the placement of chalk holder is not easy to take out, and uses inconvenience; Chalk holder adopts papery mostly, is disposable, has also caused the waste of resource.
the utility model content:
In order to make up the prior art problem, the purpose of this utility model is to provide a kind of chalk holder, reasonable in design, and easy to use, health, stable, and environmental protection, can be used repeatedly for a long time.
The technical solution of the utility model is as follows:
Chalk holder, comprise the box body that upper end is uncovered, the box body top is provided with top cover, it is characterized in that: in described box body, be slidably fitted with supporting plate, be rotatablely equipped with lifting arm on the box portion left right plate of supporting plate below, it is oval-shaped axostylus axostyle that lifting arm adopts cross section, the lifting arm right-hand member stretches out box body and the torsion handle is installed, the outer wall of lifting arm contacts with the supporting plate lower surface, before and after the box body of described supporting plate top, the side plate inwall is provided with dividing plate, dividing plate is divided into left cavity by box body, right cavity, described box portion left side plate outer wall and each turning, base plate lower surface are separately installed with sucker.
Described chalk holder is characterized in that: described box body adopts metal machine-shaping or plastics extrusion moulding to form.
Described chalk holder is characterized in that: described sucker adopts plastics extrusion moulding or magnetic material to make.
The utility model has the advantages that:
The utility model structural design novelty, by being arranged on being used in conjunction with of lifting arm in box body and supporting plate, make the chalk in box to take out easily and fast, box body left and right cavity can be placed the chalk of different colours, on this outter box, sucker is installed, can conveniently be fixed on the position needed, box body can also repeatedly utilize, and saves a large amount of costs.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to Fig. 1:
Chalk holder, comprise the uncovered box body in upper end 1, box body 1 top is provided with top cover 2, be slidably fitted with supporting plate 3 in box body 1, be rotatablely equipped with lifting arm 4 on the box portion left right plate of supporting plate 3 belows, it is oval-shaped axostylus axostyle that lifting arm 4 adopts cross section, lifting arm 4 right-hand members stretch out box body and are equipped with and reverse handle 5, the outer wall of lifting arm 3 contacts with supporting plate 2 lower surfaces, improve the height of chalk by reversing handle 5, allow the chalk upper end exceed the box body opening end, the convenient taking-up, before and after the box body of supporting plate 2 tops, the side plate inwall is provided with dividing plate 6, dividing plate 6 is divided into left cavity 7 by box body, right cavity 8, left cavity 7, right cavity 8 can be placed respectively pastel and white chalk, practical, box body 1 left plate outer wall and each turning, base plate lower surface are separately installed with sucker 9.
Sucker 9 adopts plastics extrusion moulding or magnetic material to make, and what plastics were made can directly be adsorbed on the blackboard wall or on the table top of lectern; What magnetic material was made can adsorb mutually with magnetic metal, the convenient placement.
