Description
Technical field
The present invention relates to teaching aid technical field, and in particular to a kind of teaching multi-function chalk casing.
Background technology
Chalk is the regular supplies that school teacher writes on blackboard, and now, the chalk that the country uses mainly has common chalk
With two kinds of dust-free chalk, its main component is calcium carbonate and calcium sulfate, or containing a small amount of calcium oxide.Teacher often need to be on blackboard
Writing, draw and explained.In writing, finger is directly contacted with chalk, often expires the powder that hand is white after class for one, right
Hand pollutes, to the healthy unfavorable of people.
And teacher when giving lessons, it is necessary to through common chalk-writing blackboard, flipbook or carry out other operations, when with
After the completion of chalk-writing, substantial amounts of dust will be stained with by the hand of chalk, and is capable of the environment of cleaning in time on classroom,
So carry out will being stained with when other operations again and cause inconvenience on other articles such as book, teaching aid or clothes.
The content of the invention
It is an object of the invention to provide a kind of simple in structure, the teaching multi-function chalk casing with multiple functions.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of teaching multi-function chalk casing, including set
Cylinder, the sleeve is hollow structure, is equipped with a partition plate in the sleeve, sleeve is divided into upper Storage and lower clamping by the partition plate
Area, the opening of the upper Storage are equipped with end cap, and the opening of the lower clamp area is equipped with the clamping dress for being used to clamp chalk
Put.
One kind teaching multi-function chalk casing as described above, further illustrates to be that the clamping device includes multiple bullets
Property intermediate plate, the elastic clip are circumferentially uniformly distributed along the lower clamp area opening of sleeve.
One kind teaching multi-function chalk casing as described above, further illustrates to be that the elastic clip is elastoplastic.
One kind teaching multi-function chalk casing as described above, further illustrates to be that the sleeve material is transparent plastic.
One kind teaching multi-function chalk casing as described above, further illustrates to be that the bush outer sleeve is equipped with protective case.
One kind teaching multi-function chalk casing as described above, further illustrates to be that the protective case is sponge.
The beneficial effects of the invention are as follows：The present apparatus is simple in structure, reduces use cost, easy to spread, has good
Practicality.Have the function of to store chalk at the same time and clamp chalk, avoid finger when in use and contacted with the direct of chalk, protected
Cleaning and health when holding use, and the problem of chalk is easily pulled apart when in use is avoided, also it is easily carried when outgoing, no
Easily make surrounding articles dirty.It can be easy to use with storing chalks, improve writing efficiency at the same time.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1st, sleeve；2nd, partition plate；3rd, end cap；4th, clamping device；5th, protective case；6th, chalk.
Embodiment
The specific embodiment of the invention is further elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1, one kind teaching multi-function chalk casing provided by the invention, including sleeve 1, during the sleeve 1 is
Hollow structure, is equipped with a partition plate 2 in the sleeve 1, and sleeve is divided into upper Storage and lower clamp area by the partition plate 2, i.e., upper storage
Area is used to store for future use chalk 6, and unnecessary chalk is placed on the inside, and convenient to take at any time, lower clamp area is used to clamp chalk
6。
The opening of the upper Storage is equipped with end cap 3, is closed upper Storage by end cap 3, so as to avoid
Spare chalk 6 in Storage drops.The opening of the lower clamp area is equipped with the clamping device 4 for being used for clamping chalk 6.
The clamping device 4 includes multiple elastic clips, and the elastic clip is circumferential along the lower clamp area opening of sleeve 1
It is uniformly distributed, so as to clamp chalk 6 by the cooperation between elastic clip, ensures the fluency of writing.The elastic clip
Elastoplastic can be used.
For the ease of observing the service condition of 1 inside chalk of sleeve, 1 material of sleeve can select transparent plastic.
Protective case 5 is arranged with outside the sleeve 1, protective case 5 can also play anti-skidding effect, preferably, the protection
Set 5 is sponge.By the present apparatus, finger is avoided when in use and is contacted with the direct of chalk, cleaning during use is kept and defends
It is raw, and the problem of chalk is easily pulled apart when in use is avoided, also it is easily carried when outgoing, is not easy to make surrounding articles dirty.This
Apparatus structure is simple, reduces use cost, easy to spread, has good practicality.
The present invention is not limited to examples detailed above, in claims of the present invention limited range, art technology
The various deformations or amendments that personnel can make without creative work are protected by this patent.
