본 고안은 분해조립식으로되는 흑판지우개에 관한 것으로 솜의 착탈이 용이하여 소재하기 좋고 실용적인 것이다.The present invention relates to a black cardboard eraser that is disassembled and assembled, so that the cotton can be easily attached and detached and the material is good and practical.

종래의 흑판지우개는 솜이 갈아넣을수가 없기 때문에 흡진상태가 누진되면 흑판지우개 전체를 새것으로 교환해야하는 비경제적인 불편이 있었다.In the conventional blackboard eraser, cotton can not be replaced, so when the exhausted state is exhausted, there is an uneconomic inconvenience of replacing the entire blackboard eraser with a new one.

본 고안은 위와같은 종래의 결점을 시정하기 위하여 각 부분별로 교환이 가능케 조립식으로 구성한 것인데, 이를 보다 상세히 설명하면 다음과 같다.The present invention is configured to be replaced by each part in order to correct the above conventional drawbacks, which will be described in more detail as follows.

직4각형으로된 기판(1)의 중앙부에 통공부(나)를 형성하여 개폐식 가림판(1')을 달고 저부로 용출되게 솜주머니(2)를 형성하여 기판의 통공부(나)를 통해 솜주머니(2)속에 솜(가)을 충진시키고 기판(1) 저부로 직4각형의 솜주머니가 삽입되는 통공부(3')가 형성되며, 일측으로 삽입홈(4)이 형성된 하판(3)을 밀착시키고, 기판(1) 상면으로는 삽입홈(4)과 일치되는 곳에 삽입부(5')가 형성되고, 저면 3주면에 삽입홈(6)이 형성된 상판(5)을 횡합하여 삽입홈(6)내에 기판(1)의 3주면에 삽입되게하고, 상판(5) 외면에 손잡이(8) 고정판(7)의 양측결합홈(7')이 횡삽되게한 구조이다.A through hole (b) is formed at the center of the rectangular quadrangular substrate (1) to attach an open-close shielding plate (1 '), and a cotton bag (2) is formed to elute to the bottom, through the through hole (b) of the substrate. Filling cotton (2) in the cotton bag (2) is formed in the through hole (3 ') is inserted into the bottom of the substrate (1) rectangular cotton bag, the lower plate formed with an insertion groove (4) on one side (3) ) And an inserting portion 5 'is formed on the upper surface of the substrate 1 to coincide with the inserting groove 4, and the top plate 5 having the inserting groove 6 formed on the bottom 3 main surfaces is transversely inserted. The grooves 6 are inserted into the three main surfaces of the substrate 1, and both coupling grooves 7 'of the handle 8 fixing plate 7 are horizontally inserted into the outer surface of the upper plate 5.

이와같이된 본 고안은 손잡이(8) 고정판(7)은 양측결합홈(7')으로 인해 상판(5)에서 분리결합되고, 상판(5)은 기판(1)과 하판(3)의 3주면을 감싸 결합하게 되며, 하판(3)의 일측삽입홈(4)에 상판(5)의 삽입부(5')가 결합되므로 차례로 결합하면 흑판이되고, 역순으로 분해하면 기판(1)이 노출되기 때문에 기판(1) 가운데에 형성된 통공부(나)의 가림판(1')을 열고 내부의 솜(가)을 인출하여 분리한다음 그속에 새솜을 투입하고 다시 결합하여 새것처럼 사용할수 있는 장점이 있고, 각부분이(상판, 하판, 기판, 손잡이)하나하나 분해 결합되기 때문에 만들기 쉽고 사용하기 좋으며, 부분적인 교환이 가능하며 실용적인 이점을 얻을수 있는 것이다.The present invention as described above, the handle (8) fixed plate (7) is separated from the upper plate (5) by the two side coupling groove (7 '), the upper plate (5) is the three main surfaces of the substrate (1) and the lower plate (3) Since the inserting portion 5 'of the upper plate 5 is coupled to the one side insertion groove 4 of the lower plate 3, it is combined with the black plate, and the substrate 1 is exposed when disassembled in the reverse order. Open the screening plate (1 ') of the through hole (b) formed in the center of the substrate (1) and draw out and separate the cotton inside (a) has the advantage that can be used as a new by putting the cotton wool in it again and combine again , Each part (top plate, bottom plate, board, handle) is disassembled and combined one by one, making it easy to use, easy to use, partial exchange is possible, and practical advantages can be obtained.

Claims

As shown in the drawing, a through hole (b) is formed in the center of the rectangular quadrangular substrate (1), and a cotton bag (2 ') is formed by attaching an open-close shielding plate (1') and eluting to the bottom. Filling the cotton (ga) in the cotton bag (2) through the study (b), a through hole (3 ') that is formed into a rectangular cotton bag to the bottom of the substrate (1) is formed, the insertion groove ( 4) is formed in close contact with the lower plate 3, the upper surface of the substrate 1 is formed with an insertion portion 5 'is formed in the same position as the insertion groove (4) and the upper groove (3) 5) transversely inserted so that the insertion groove 6 is inserted into the three main surfaces of the substrate 1, and both side coupling grooves 7 'of the handle 8 fixing plate 7 are transversely inserted into the outer surface of the upper plate 5. Prefabricated blackboard eraser.
