Abstract
The invention discloses a kind of anti-skidding chalk sleeve of double end, including main body, penholder and Anti-slip cover, main body includes rotation cylinder and the pen cap, penholder two ends are respectively symmetrically and are provided with rotation cylinder and the pen cap, Anti-slip cover is set on penholder and Anti-slip cover outer surface is also evenly arranged with anti-skid bulge, and pen cap inside bottom is also coaxially arranged with clamp structure.The anti-skidding chalk sleeve of double end disclosed by the invention, simple structure, it is easy to use, chalk is grasped in use firm, avoid the directly contact of chalk and hand during writing on the blackboard, the hand guard glove of the flexible structure by setting, is avoided that long-term assurance rigid and damages hand, so as to avoid the corrosion and injury of chalk and chalk sleeve to hand simultaneously.
Description
Technical field
The present invention relates to a kind of realia, particularly a kind of anti-skidding chalk sleeve of double end.
Background technology
Chalk is an indispensable teaching aid in learning activities in schools, and it is generally tempered and moulded to dry and obtained by gypsum, appropriate binding agent and pigment etc..Clear for the convenience write and writing on the blackboard stroke, the content of the binding agent in usual chalk can be controlled in relatively low level.And gypsum is the material that powder-type has absorbent function simultaneously, have the shortcomings that matter is crisp during use and dust etc., if the long-term directly hand of user is held simultaneously, human body can be caused aging the skin human body of the corresponding contact portion of finger, and promote the generation of corrosion damage.It is thus the hand of protection user, the appearance of the anti-skidding chalk sleeve of double end just seems just right.General chalk sleeve is all using the structure of shaft-like pushing out type container.Simultaneously pass through daily life experience it is recognised that long-time grasp chalk when, hand is easily numb, and easily slides and broke chalk, not only can manufacturing environment rubbish can also cause resource property waste, particularly summer perspire it is more when it is particularly true.Generally need to use the chalk of multiple color in education activities, if only single chalk sleeve, it is necessary to do not stop to change, or directly hand is taken, and using inconvenience, influences efficiency of teaching.
The content of the invention
To solve the above problems, the anti-skidding chalk sleeve of double end disclosed by the invention, simple structure is easy to use, low processing cost, the Anti-slip cover of grasping of the chalk simultaneously by setting can be securely grasped in use, so as to reduce corrosion and landing of the chalk to hand in long-term use, it is ensured that hand health and grasping are firm, two chalks can simultaneously be loaded, avoid ceaselessly replacing chalk in teaching, be education activities provides convenient, improve writing on the blackboard efficiency.
The anti-skidding chalk sleeve of double end disclosed by the invention, including main body, penholder and Anti-slip cover, the main body includes rotation cylinder and the pen cap, the penholder two ends are respectively symmetrically and are provided with rotation cylinder and the pen cap, the Anti-slip cover is set on penholder and Anti-slip cover outer surface is also evenly arranged with anti-skid bulge, and the pen cap inside bottom is also coaxially arranged with clamp structure.The anti-skidding chalk sleeve of double end disclosed by the invention, simple structure is firm, it is easy to use, low processing cost, by the Anti-slip cover being arranged on outside rotation cylinder, chalk can not only be securely grasped in use, slid so as to be effectively prevented from chalk and hand Long Term Contact fatigue, while corrosion of the chalk in reducing long-term use to hand ensures hand health, assurance ability of the hand to chalk sleeve can also be improved, avoid dropping and polluting environment and waste of resource, long service life, application cost is low, can once fill two chalks simultaneously, reduce the frequency that chalk is changed during writing on the blackboard, so as to improve the efficiency of traditional instruction, for education activities be normally carried out bring conveniently.
A kind of improvement of the anti-skidding chalk sleeve of double end disclosed by the invention, the clamp structure is fixed on pen cap bottom for lower end, and upper end is the drum structure of the barrier of activity claw type.This improvement is the clamp structure of active type by the upper end for setting, simple structure, the handling difficulty of chalk is not only reduced in use, simplify the structure of the anti-skidding chalk sleeve of double end with going back some simultaneously, grasping ability of the anti-skidding chalk sleeve of double end to chalk is also effectively enhanced, convenience and service efficiency that the anti-skidding chalk sleeve of double end is used is improve.
The anti-skidding chalk sleeve of double end disclosed by the invention, simple structure is firm, it is easy to use, without frequently changing chalk in education activities, low processing cost, can securely grasp chalk in use, reduce because long-time assurance chalk produces fatigue to slide, avoid wasting the appearance of the situations such as chalk, pollution environment, influence environment, while also improving the efficiency of teaching.
