Description
Technical field
The present invention relates to teaching aid technical field, and in particular to a kind of teaching chalk sleeve.
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 teaching chalk sleeve simple in structure, practical convenient.
In order to achieve the above object, the technical solution adopted by the present invention is：Teaching chalk sleeve, including cylinder, it is described
Cylinder is hollow structure, a partition plate is equipped with the cylinder, cylinder is divided into upper Storage and lower clamp area by the partition plate, described
The upper Storage opening of cylinder is equipped with end cap, and the end cap is flexibly connected with cylinder, and the lower clamp area of the cylinder, which is equipped with, to be used
In the fixing bolt of fixed chalk, the cylinder is equipped with the threaded hole being adapted with fixing bolt, and the fixing bolt passes through
Threaded hole pushes against the chalk being located under cylinder in clamp area.
Teaching chalk sleeve as described above, further illustrates to be that the end cap is connected with cylinder screw.
Teaching chalk sleeve as described above, further illustrates to be that the end cap is clamped with cylinder, is set on the end cap
There is lug, the cylinder is equipped with the groove being adapted with lug.
Teaching chalk sleeve as described above, further illustrates to be to be arranged with protective case outside the cylinder.
Teaching chalk sleeve as described above, further illustrates to be that the protective case material is rubber.
Teaching chalk sleeve as described above, further illustrates to be that the protective case is equipped with antiskid groove.
Teaching chalk sleeve 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.Avoid finger when in use to contact with the direct of chalk, cleaning and health when keeping using, and avoid powder
The problem of pen is easily pulled apart when in use, is also easily carried when outgoing, is not easy to make surrounding articles dirty.By setting partition plate, not
Fixing bolt, can be placed in the upper Storage of cylinder by the used time, avoid dropping for fixing bolt, while be beneficial to the present apparatus
Storage.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1st, cylinder；2nd, partition plate；3rd, end cap；4th, fixing bolt；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, teaching chalk sleeve provided by the invention, including cylinder 1, the cylinder 1 is hollow structure, institute
State and a partition plate 2 is equipped with cylinder 1, the partition plate 2 divides cylinder 1 for upper Storage and lower clamp area, the upper storage of the cylinder 1
Area's opening is equipped with end cap 3, and the end cap 3 is flexibly connected with cylinder 1, so as to so that end cap 3 is split with cylinder 1.Institute
State between end cap 3 and cylinder 1 to use and be threadedly coupled, can also use and be clamped between the end cap 3 and cylinder 1, by
Lug is set on the end cap 3, the groove being adapted with lug is set on the cylinder 1, so that lug is connected to groove
In.By setting partition plate 2 to set up upper Storage, fixing bolt 4 is stored to wherein, is avoided easy to the device when not used
Dropping for fixing bolt 4, will hereafter be specifically described fixing bolt 4.
The lower clamp area of the cylinder 1 is equipped with the fixing bolt 4 for being used for fixing chalk 6, and the cylinder 1 is equipped with and fixation
The threaded hole that bolt 4 is adapted, the fixing bolt 4 push against the chalk 6 in 1 time clamp area of cylinder through threaded hole.From
And ensure that chalk 6 is stable and firm when being write, it ensure that the fluency of writing.Avoid finger when in use and powder at the same time
Pen 6 directly contacts, cleaning and health when keeping using, and avoids the problem of chalk 6 is easily pulled apart when in use, outside
Also it is easily carried when going out, is not easy to make surrounding articles dirty.
Protective case 5 can be arranged outside cylinder 1.The material of the protective case 5 can use rubber, when using rubber,
Antiskid groove can also be equipped with protective case 5.The protective case 5 can also select sponge.Certainly others can also be used
Material, is not illustrated one by one here.The present apparatus is simple in structure, reduces use cost, easy to spread, has practical well
Property.
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.
