Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below Content disclosed by specification understands other advantages and effect of the utility model easily.

It please refers to Fig.1.It should be clear that the structure depicted in this specification institute accompanying drawings, only coordinating disclosed in specification Content, for those skilled in the art understand and read, be not limited to the enforceable qualifications of the utility model, Therefore not having technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing this reality With under novel the effect of can be generated and the purpose that can reach, should all still falling in the revealed technology contents institute of the utility model In the range of capable of covering.Meanwhile it is cited such as "upper", "lower", "left", "right", " centre " and " one " in this specification Term is merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, the change of relativeness Or adjustment, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.

Referring to Fig. 1, a kind of damp proof chalk box structural schematic diagram of the utility model is shown as, as shown in Figure 1, this practicality A kind of novel damp proof chalk box of offer, including：Damp proof chalk box includes：Box body 1, hollowed-out board 2 and short nib screen out component 3；Box Body 1 is a cube hollow structure, and 1 internal structure of box body is penetrating, 1 interior space dimension of box body and standard chalk length and specific The sectional dimension of quantity is adapted, and is suitable for storage chalk and detection box inner powder stroke count amount；2 size of hollowed-out board is opened with 1 top of box body Mouth size is coincide, and is movably installed in the bottom end in box body 1, trepanning is arranged on hollowed-out board 2, pass through suitable for shorter chalk end；It is short Nib screens out component 3 and is located at the lower section of hollowed-out board 2, and is movably connected on the bottom end of box body 1, and the powder of chalk holder is sifted out by hole Nib falls into short nib and screens out the short nib for being suitable for extracting out inadequacy in component 3.

Hollowed-out board 2 includes：Multiple strip holes 21 being arranged in parallel on hollowed-out board 2, strip hole 21 are multiple, are arranged in parallel In on hollowed-out board 2, it is preferred that strip hole 21 can be corner rectangular opening or round rectangle hole, be suitable in chalk it is less, be distributed in anti- When the bottom of damp chalk holder, lift hollowed-out board 2 with finger so that hollowed-out board 2 forms certain slope, and taking out the chalk of bottom makes With.

21 size of strip hole is less than whole standard chalk length, and the pre-set dimension of strip hole 21 is for screening out the short of inadequacy Chalk end retains longer chalk in tray interior, and chalk is placed perpendicular to strip hole 21 so that longer chalk can not pass through Strip hole achievees the effect that leak out short chalk end.

Short nib screens out component 3：Screen out net 31 and cleaning box 32；The mesh size for screening out net 31 is less than whole standard Chalk length；Cleaning box 32, which is set to, screens out 31 lower section of net, screens out net 31 and is set between cleaning box 32 and hollowed-out board, short chalk Head is entered by screening out net 31 in cleaning box 32 after leaking out hollowed-out board 2.

Cleaning box 32 includes：Box body containing component 321 and cleaning box body 322；Box body containing component 321 is fixedly installed in box Body bottom outside after short chalk end is screened out, drops down onto in cleaning box body 322, and cleaning box body 322 is transparent material；Clear up box body 322 upper openings, cleaning 322 activity of box body are inserted in box body containing component 321, and box body containing component 322 clears up box body 322 be a drawer system, extracts out and abandons therein when user has observed that short chalk end is fallen into cleaning box body 322 Short nib is reinserted later in box body containing component 321, and box body containing component 321 is whole penetrating.

Cleaning box 32 is transparent cartridge structure, and cleaning box 32 is processed into using transparent plastic, is fallen convenient for user's observation The number for entering short chalk end therein extracts the chalk end fallen into cleaning box 32 out in time convenient for user.

Number is no less than two alignment connections of box body 1, and the setting drier holding tank 4 in junction, multiple box bodys 1 are in a row It is arranged, space storage drier is arranged for keeping chalk inside damp proof chalk box to dry in junction between box body.

Box body 1 is transparent cartridge, and box cover 5 is hingedly arranged at 1 upper opening of box body, and square case cap is also penetrating knot on box body 1 Structure is suitable for the number of chalk in user's box body viewed from above.
