Description
Technical field
The utility model relates to a kind of chalk holder that can save chalk, belongs to realia technical field of structures.
Background technology
Chalk is requisite educational aid in daily teaching, mostly teacher is to be directly positioned in chalk holder or in blackboard slot or on platform table after being finished chalk, when using next time, may not can use the chalk that previously oneself used, but directly to an optional new chalk in chalk holder, use, so if things go on like this, can cause part chalk to concentrate in blackboard slot, part chalk is different in size being staggered in chalk holder, calculating like this gets off can waste a lot of chalks, increased instruction cost, waste resource.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, easy to use, can effectively save chalk, improves the chalk holder that can save chalk of chalk utilization rate.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of chalk holder that can save chalk, comprise chalk holder box body 1, top port one side shaft of chalk box body 1 is connected to lid 2, its special character is that the bottom of box body 1 is provided with drawer type chalk end accumulator tank 9, the place, sidewall top position of box body 1 is provided with axle 3, one end of axle 3 is provided with the sleeve pipe 4 that can rotate around axle 3, the internal diameter of sleeve pipe 4 and the butt diameter of chalk match, the outer wall of sleeve pipe 4 is provided with scale, one end opening of chalk sleeve 4, near being arranged with on the outer wall of this port, can rotate along sleeve pipe 4, for propping up the blend stop 6 of lid 2, the one side that blend stop 6 contacts with lid 2 has been provided with the foam-rubber cushion 7 that reduces rubbing action, the other end of sleeve pipe 4 is provided with boosting bar 5, boosting bar 5 is T-shaped and partly stretches into sleeve pipe 4 inside,
Further:
One end of described blend stop 6 is provided with for the fixing card pipe 8 of lettering pen, and card pipe 8 is for hollow structure and made by silica gel material.
Beneficial effect: compared with prior art, the utility model reasonable in design, teacher takes out chalk bonnet upper box cover first in box body, by blend stop, lid is further fixed, prevent from when teacher from using next time directly in box body, taking new chalk, teacher uses after chalk, chalk is placed in sleeve pipe, next time is when used, by boosting bar, chalk is released, by scale set on sleeve pipe, can know the length of chalk, if chalk is used by too short can not continuation, rotating casing, make the boost tube of sleeve pipe be positioned at top, the mouth of pipe is aimed at accumulator tank, now press down boosting bar, chalk end in sleeve pipe is pushed in accumulator tank, then rotate blend stop, open the lid, taking out new chalk continues to use, the utility model reasonable in design, arriving finally of a chalk can being used always changed again again, accumulator tank can collect chalk end, for subsequent recovery utilization, effectively improve resource utilization.
Accompanying drawing explanation
Fig. 1: a kind of structural representation that can save the chalk holder of chalk of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment
A kind of chalk holder that can save chalk of the present embodiment, comprise chalk holder box body 1, top port one side shaft of chalk box body 1 is connected to lid 2, the bottom of box body 1 is provided with drawer type chalk end accumulator tank 9, the place, sidewall top position of box body 1 is provided with axle 3, one end of axle 3 is provided with the sleeve pipe 4 that can rotate around axle 3, the internal diameter of sleeve pipe 4 and the butt diameter of chalk match, the outer wall of sleeve pipe 4 is provided with scale, one end opening of chalk sleeve 4, near being arranged with on the outer wall of this port, can rotate along sleeve pipe 4, for propping up the blend stop 6 of lid 2, the one side that blend stop 6 contacts with lid 2 has been provided with the foam-rubber cushion 7 that reduces rubbing action, the other end of sleeve pipe 4 is provided with boosting bar 5, boosting bar 5 is T-shaped and partly stretches into sleeve pipe 4 inside, one end of blend stop 6 is provided with for the fixing card pipe 8 of lettering pen, and card pipe 8 is for hollow structure and made by silica gel material.
Using method: teacher is first from the interior taking-up chalk of box body 1 bonnet upper box cover 2, by blend stop 6, lid 1 is further fixed, prevent from when teacher from using next time directly in box body 1, taking new chalk, teacher uses after chalk, chalk is placed in sleeve pipe 4, next time is when used, by boosting bar 5, chalk is released, by 4 set scales on sleeve pipe, can know the length of chalk, if chalk is used by too short can not continuation, rotating casing 4, make the boosting bar 5 of sleeve pipe 4 be positioned at top, the mouth of pipe is aimed at accumulator tank 9, now press down boosting bar 5, chalk end in sleeve pipe 4 is pushed in accumulator tank 9, then rotate blend stop 6, open the lid 2, taking out new chalk continues to use, the utility model reasonable in design, arriving finally of a chalk can being used always changed again again.
The utility model reasonable in design, easy to use, can effectively save chalk, improve chalk utilization rate.
