Abstract
The utility model discloses a chalk box with chalk convenient to take out and belongs to an education supply. The chalk box can effectively solve the problem that the chalk cannot be conveniently taken out when a teacher gives a lesson. The structure of the chalk box comprises an n-shaped board frame, wherein a three-edge-shaped support pillar is arranged at a middle position of an upper flat board in the n-shaped board frame in a fixedly and downward mode, a cavity shaped like a reversed triangle is formed on each of the two sides of the three-edge-shaped support pillar, and a chalk outlet is arranged between each of the two ends of the bottom face of the three-edge-shaped support pillar and each of the two vertical boards of the n-shaped board frame. The bottom face of the three-edge-shaped support pillar is fixed on a base through a support board. Two ends of the base are respectively upward provided with a block board in reversed three edge shape through a rotating shaft. Besides, a holding board is arranged on each rotating shaft in an outward mode. A spring is arranged between the inner side of each block board in reversed three edge shape and the base. The chalk box with the chalk convenient to take out has the advantages of being easy to operate, convenient to use and applicable to places such as a school and a training institution.
Description
Technical field
The utility model relates to a kind of realia, especially a kind of chalk holder of the chalk of being convenient to take.
Background technology
In the daily life, in school, main realia in chalk and blackboard or some schools.And in teacher's teaching process, often need to use white chalk and pastel, be convenient to mark emphasis.And generally, white chalk and pastel all are in disorder being placed in the chalk holder, and be very inconvenient when teacher takes, and affected the efficient of giving lessons.
The utility model content
Technical assignment of the present utility model is the chalk holder that a kind of chalk of being convenient to take is provided for above-mentioned deficiency of the prior art, and this chalk holder can effectively solve the problem of the chalk inconvenience of taking when teacher gives lessons.
The technical scheme that its technical problem that solves the utility model adopts is: this kind be convenient to take chalk holder of chalk, it is characterized in that, its structure comprises a N-shaped grillage, the upper flat plate centre position is fixed with a prismatic pillar downwards in the described N-shaped grillage, so that prismatic pillar both sides respectively form the cavity of an inverted-triangular, leave respectively chalk outlet between two risers of described two ends, prismatic pillar bottom surface and N-shaped grillage; Described prismatic pillar underrun support plate is fixed on the base, and described base two ends upwards are provided with the type of falling a triangular baffle plate by rotating shaft respectively, also outwards is provided with respectively a supporting plate in the described rotating shaft; Also be respectively equipped with spring between the described baffle plate of falling prismatic inboard and the base.
The utlity model has following outstanding beneficial effect:
1, because the interior upper flat plate centre position of described N-shaped grillage is fixed with a prismatic pillar downwards, so that prismatic pillar both sides respectively form the cavity of an inverted-triangular, leave respectively chalk outlet between two risers of described two ends, prismatic pillar bottom surface and N-shaped grillage, so it can store chalk in the inverted triangle cavity, can under Action of Gravity Field, skid off at the chalk outlet place simultaneously.
2, because described prismatic pillar underrun support plate is fixed on the base, described base two ends upwards are provided with the type of falling a triangular baffle plate by rotating shaft respectively, also outwards are provided with respectively a supporting plate in the described rotating shaft; Also be respectively equipped with spring between the described baffle plate of falling prismatic inboard and the base, so it can be by upwards breaking supporting plate off with the fingers and thumb, chalk can skid off and drop on the supporting plate, is convenient to teacher and takes, and spring can reset baffle plate simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of facing of the present utility model.
Description of reference numerals: 1n template frame, 2 prismatic pillars, 3 first baffle plates of falling the prismatic, 4 first supporting plates, 5 first rotating shafts, 6 first springs, 7 bases, 8 support plates, 9 second springs, 10 second rotating shafts, 11 second supporting plates, 12 second baffle plates of falling the prismatic, 13 chalks.
The specific embodiment
As shown in Figure 1, this kind be convenient to take chalk holder of chalk, its structure comprises a N-shaped grillage 1, described N-shaped grillage 1 interior upper flat plate centre position is fixed with a prismatic pillar 2 downwards, so that prismatic pillar 2 both sides respectively form the cavity of an inverted-triangular, leave respectively chalk outlet between two risers of described prismatic pillar two ends, 2 bottom surface and N-shaped grillage 1; Described prismatic pillar 2 underrun support plates 8 are fixed on the base 7, described base 7 two ends upwards are provided with the first type of falling triangular baffle plate 3 and the second type of falling triangular baffle plate 12 by the first rotating shaft 5 and the second rotating shaft 10 respectively, also outwards are provided with respectively the first supporting plate 4 and the second supporting plate 11 in described the first rotating shaft 5 and the second rotating shaft 10; Also be respectively equipped with the first spring 6 and the second spring 9 between described the first baffle plate of falling the prismatic 3 and the second baffle plate of falling the prismatic 12 inboards and the base 7.
During use, the chalk outlet of the first baffle plate of falling the prismatic 3 and the second baffle plate of falling the prismatic 12 tops both can skid off chalk 13, also after chalk 13 is finished, put into mouth as chalk, whole box body can be inverted when putting chalk 13, in two cavitys, place respectively white chalk and pastel.When getting chalk, upwards lift respectively the first supporting plate 4 and the second supporting plate 11, then the first type of falling triangular baffle plate 3 and the second type of falling triangular baffle plate 12 inwardly rotate, chalk 13 can skid off under Action of Gravity Field, the first type of falling triangular baffle plate 3 and the second type of falling triangular baffle plate 12 reset under the first spring 6 and 9 effects of the second spring after taking out, and be very easy to use.
