Description
Technical field
The present invention relates to teaching aid technical field, and in particular to a kind of teaching chalk hand guard glove.
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 hand guard glove simple in structure, easy to use.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of teaching chalk hand guard glove, including set
Cylinder, the sleeve are hollow structure, and one end of the sleeve is equipped with the clamping device for being used for clamping chalk, and the sleeve is externally provided with
Protective case, the protective case is interior to be equipped with heating unit, and the heating unit includes heating wire, switch and the power supply of series connection.
A kind of teaching chalk hand guard glove as described above, further illustrates to be that the clamping device includes multiple elasticity
Intermediate plate, the elastic clip are circumferentially uniformly distributed along sleeve.
A kind of teaching chalk hand guard glove as described above, further illustrates to be that the quantity of the elastic clip is 4.
A kind of teaching chalk hand guard glove as described above, further illustrates to be that the elastic clip is elastoplastic.
A kind of teaching chalk hand guard glove as described above, further illustrates to be that the protective case is externally provided with antiskid groove.
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.Operation is very easy at the same time, improves the work efficiency attended class.Avoid finger when in use and the direct of chalk connects
Touch, cleaning and health when keeping using, and avoid the problem of chalk is easily pulled apart when in use, also easily taken when outgoing
Band, is not easy to make surrounding articles dirty.By setting heating unit to be heated when temperature is relatively low to the sleeve of the device,
So as to be not easy to freeze hand, make the letter written with chalk that writing comes out more beautiful, greatly improve user experience.

Fig. 2 is schematic diagram of heating device.
In figure：1st, sleeve；2nd, clamping device；3rd, protective case；4th, heating wire；5th, switch；6th, power supply；7th, chalk.
Embodiment
Embodiment of the present invention is further elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of teaching chalk hand guard glove provided by the invention, including sleeve 1, the sleeve 1 are hollow
Structure, the aperture of sleeve 1 are adapted with chalk 7.One end of the sleeve 1 is equipped with the clamping device 2 for being used for clamping chalk 7, i.e.,
Chalk 7 is clamped by clamping device 2, thus by sleeve 1 drive chalk 7 write, avoid when in use finger with
Chalk directly contacts, cleaning and health when keeping using, and avoids the problem of chalk is easily pulled apart when in use, outside
Also it is easily carried when going out, is not easy to make surrounding articles dirty.
The clamping device 2, which can use, includes multiple elastic clips, and the elastic clip uniformly divides along sleeve 1 is circumferential
Cloth.The quantity of the elastic clip is preferably 4.The material of the elastic clip can use elastoplastic.
The sleeve 1 is externally provided with protective case 3, and heating unit is equipped with the protective case 3, and the heating unit includes series connection
Heating wire 4, switch 5 and power supply 6, concrete structure is as shown in Figure 2.When needing to be heated, by lower switch 5, this
When heating wire 4 generate heat, so as to be heated to protective case 3.Certainly other heating equipments can also be selected.By setting heating dress
Put and the sleeve of the device can be heated when temperature is relatively low, so as to be not easy to freeze hand, make the letter written with chalk that writing comes out more
Beauty, greatly improves user experience.
Antiskid groove can also be set outside protective case 3.The present apparatus is simple in structure, reduces use cost, easy to spread,
With 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.
