Abstract

The utility model relates to a teaching aid, in particular to a moisture resistant chalk box. The utility model mainly solves the problem of the prior chalk box that the chalk storage is inclined to be affected with damp. The moisture resistant chalk box comprises a rectangular outer casing and a box cover, a metal gauze is vertically connected on a trapezoidal base seat, moisture resistant desiccating agent is installed at the interlayer between the metal gauze and the outer casing, a chalk storage space is formed between an inner wall and the metal gauze, and a blocking plate is connected at the front end of the trapezoidal base seat to block the rolled out chalk. When being used, the chalk box cover needs not to be opened, a dry chalk can be directly withdrawn form a groove of the blocking plate, when not being used, the chalk is only required to be placed into the chalk storage space from an upper opening once, the box cover is closed, and the utility model can effectively perform the moisture resistant function.

Description

The damp proof chalk box

Technical field

The utility model relates to a kind of teaching aid, specifically a kind of damp proof chalk box.

Background technology

At present, existing chalk holder all is the box made from paper, and does not have lid, and chalk is variable damp in overcast and rainy malaria environment like this, thereby can't use, and causes a large amount of waves.

Summary of the invention

The purpose of this utility model: be at the defective of existing chalk holder, a kind of convenience, practical damp proof chalk box are provided.

The utility model is achieved in that the damp proof chalk box, comprise rectangle shell and lid, the pencil box material all adopts the plastics manufacturing, wire netting is vertically connected on the trapezoidal base, between wire netting and shell interlayer, the moisture protected dry drying prescription is housed, constitute the chalk parking space between the inwall wire netting, baffle plate be connected trapezoidal base before bring in and be used to block the chalk that rolls out.

The beneficial effects of the utility model are: chalk is covered lid by in the disposable closed box of packing into, can effectively play moisture-proof role, need not open the chalk lid during use, directly can get dry chalk from blind recess, when not using, chalk has the moisture protected dry drying prescription moisture absorption all around in box, the drying that can keep chalk for a long time, because trapezoidal base is an inclined-plane, in the gravity effect, chalk can glide by automatic rolling, after chalk skids off plastic casing, blocked by baffle plate.When teacher took out one, second can then skid off.The utlity model has simple in structurely, easily row does not take up space, moistureproof advantage.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure 1, base, 2, baffle plate, 3, chalk, 4, the moisture protected dry drying prescription, 5, wire netting, 6, the chalk parking space, 7, lid, 8, shell.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment: damp proof chalk box, comprise rectangle shell 8 and lid 7, the pencil box material all adopts the plastics manufacturing, wire netting 5 is vertically connected on the trapezoidal base 1, between wire netting 5 and shell 8 interlayers, moisture protected dry drying prescription 4 is housed, constitute chalk parking space 6 between the inwall wire netting 5, baffle plate 2 be connected on trapezoidal base 1 before bring in and be used to block the chalk that rolls out.

During use, need not open the chalk lid, directly can get dry chalk 3, when not using, only need the chalk chalk parking space 6 of packing into be covered lid 7, can effectively play moisture-proof role from upper inlet is disposable from blind recess.
