본 고안은 샤아프펜슬의 절손심제거구에 관한 것이다. 종래에는 제3도에서 보는 바와 같이 노크캡(cap) 내단에 핀(p)을 설치하되, 상기 핀(p)의 중앙부에 굴곡부를 형성시켜 심파이프(a)의 내벽에 접촉되게 함으로써 노크캡을 심파이프(a) 내부에 끼웠을 때의 헐거울을 방지하게하도록 하였다.The present invention relates to a sharpness removal port of the mechanical pencil. Conventionally, as shown in FIG. 3, a pin p is installed at an inner end of a knock cap, and a bent portion is formed at the center of the pin p to contact the inner wall of the seam pipe a. It was to prevent the loose when inserted into the inside of the seam pipe (a).
그러나 이와 같은 구성에 의하면 단순히 굴곡부의 일부가 약한 탄성으로 내벽에 접촉되는 것이 고작이므로 노크캡을 심파이프(a) 내부에 끼웠을시의 록(lock) 상태를 유지하기 위해 따로 밴드부(b)를 필요로 하였기 때문에 충분히 헐거움을 방지할 수 없는 결점이 있었다.However, according to such a configuration, since only a part of the bent portion is in contact with the inner wall with weak elasticity, the band portion b is separately set to maintain the lock state when the knock cap is inserted into the inside of the seam pipe (a). There was a defect that it could not be prevented sufficiently loose because it was necessary.
본 고안은 이와 같은 결점을 제거하기 뒤하여 정부의 심파이프내에 소경부와 대경부로 이루어진 노크캡을 삽입 설치하고 상기 소경 부에는 장방형의 수평홈이 형성되도록 하여 상기 수됨홈에 정형의 굴곡부와 U자형의 절곡부를 형성시킨 절손심제거핀을 끼우되 상기 절손심의 제거핀 한쪽은 수평홈에서 돌출되도록하고 U자형의 절곡부는 소경부와 연장되게 형성된 내경부의 장공에 끼워져서 고정되게 하여 상기 컵형의 굴곡부 심파이프 내경에 접촉하게 하므로써 노크캡의 끼움을 확실히 할수 있는 샤아프 펜슬의 절손심제거구를 제공함에 있다.The present invention, after removing the defects such as inserting the knock cap consisting of a small diameter portion and a large diameter portion in the seam pipe of the government and to form a rectangular horizontal groove in the small diameter portion is formed in the bent groove and the U-shaped Insert the bent core removing pin forming the bent portion of the bent core so that one side of the pin is removed from the horizontal groove and the U-shaped bent portion is inserted into the long hole of the inner diameter formed to extend with the small diameter portion to be fixed to the cup-shaped bent portion In order to ensure the knock cap fits by contacting the inner diameter of the seam pipe, it is provided with a sharpness removing port of the sharp pencil.
본고안은 캡부(1)의 심파이프(2) 내에 소경부(3)와 대평분(4)로 이루어진 노크캡(5)을 삽입설치하고,The present insert inserts and installs the knock cap (5) consisting of a small diameter portion (3) and a large flat portion (4) in the seam pipe (2) of the cap portion (1),
삳기 소경부(3)에는 장방형의 수평홈(6)이 소경부(3) 단부와 연장되는 대경부(4) 중간부 까지는 장공(6a)을 각각 형성시키며, 컵형의 굴곡부(7)와 U자형의 절곡부(8)를 갖춘 절손심제거핀(9)을 상기 수평홈(6)과 장공(6a)으로 끼우되 굴곡부(7)는 심파이프(2) 내경에 접촉되도록 하고 절곡부(8)는 장공(6a)에 압입고정 되도록 한구조로 되어 있다.In the small-diameter portion 3, a rectangular horizontal groove 6 forms a long hole 6a up to the middle portion of the large-diameter portion 4 extending from the end portion of the small-diameter portion 3, respectively, and the cup-shaped bend portion 7 and the U-shape are formed. Insert the bent core removal pin (9) having the bent portion (8) of the horizontal groove (6) and the long hole (6a), but the bent portion (7) is in contact with the inner diameter of the seam pipe (2) and the bent portion (8) Has a structure to be press-fitted into the long hole 6a.
미설명부호 10은 호울더, 11은 선단캡, 12는 선단파이프, 13은 심이다. 이하 본 고안의 구성 및 작용효과를 첨부된 도면과 함께 상세히 설명하면 다음과 같다.Reference numeral 10 is a holder, 11 is a tip cap, 12 is a tip pipe, and 13 is a shim. Hereinafter, the configuration and operation effects of the present invention will be described in detail with the accompanying drawings.
제1도에 있어서(10)은 호울더이고 이 호울더(10)내에는 세경(細徑)의 심파이프(2)가 축 방향으로 슬라이드 자재로 수납되도록하며 또 호울더(10)의 선단으로는 선단캡(11)을 나사 맞춤으로 한다. 그리고 도시는생략하나 선단캡(11) 내에는 심파이프(2)의 선단에 연결된 리이드척기구가 설치되도록하고 상기 리이드척가구는 심파이프(2)의 이동에 의해 구동되도록 하며 선단 파이프(13)에서는 심(3)이 나오도록 되어있다.한편 노크캡(5)은 상기 심파이프(2) 내에 삽입되는 소경부(3)와 이 소경부(3)에 연속하는 대경부(4)로구성되도록 하였다.In FIG. 1, 10 is a holder, and inside the holder 10, the narrow pipe 2 is accommodated as a slide material in the axial direction, and the tip of the holder 10 is The end cap 11 is screwed. Although not shown in the drawing, the lead chuck mechanism connected to the tip of the seam pipe 2 is installed in the tip cap 11, and the lead chuck furniture is driven by the movement of the seam pipe 2 and the tip pipe 13 is provided. The knock cap (5) is composed of a small diameter portion (3) inserted into the shim pipe (2) and a large diameter portion (4) continuous to the small diameter portion (3). It was.
그리고 소경부(3)에는 수평홈(6)이 형성되도록하고 수평홈(6)과 연장되는 대경부(4) 중단부 까지는 장공(6a)이 형성되도록 하였고, 상기 소경부(3)의 수평홈(6)은 한쪽편이 개방되게하며, 대경부(4)의 장공(6a)으로는 절곡부(8)가 삽입되어 고정되도록 하였다.In addition, the small diameter portion 3 is formed such that the horizontal groove 6 is formed, and the long groove 6a is formed up to the horizontal groove 6 and the large diameter portion 4 which is extended, and the horizontal groove of the small diameter portion 3 is formed. 6, one side was opened, and the bent portion 8 was inserted and fixed into the long hole 6a of the large diameter portion 4.
또한 절손심제거핀(9) 한쪽 단부의 절곡부(8)를 장공(6a)에서 고정되게하고 절손심의 제거핀(9) 중앙부에 형성시킨 글곡부(7)를 심파이프(2) 저경에 접촉하게 하므로써 노크캡(5)이 캡부(1)에서 쉽기 빠지지않게 된다.In addition, the bent portion (8) at one end of the wick removal pin (9) is fixed in the long hole (6a), and the writing portion (7) formed in the center of the removal pin (9) of the wick core contact the seam pipe (2) bottom diameter By doing so, the knock cap 5 does not easily fall out of the cap 1.
그리고 굴곡부(7)는 소경부(3)의 수평홈(7) 위쪽으르 약간 돌출된 상태로 심파이프(2) 내경과 접촉되게하고 절손심제거핀(5) 한쪽 단부는 스증탁(3)의 수평홈(6)에서 호울더(10)쪽으로 돌출되도록 한다.따라서, 지금 상기의 상태에서와 같이 노크캡(5)을 심파이프(2)에 끼우면 제거핀(9)의 굴곡부(7)가 심파이프(2)의 내벽면에대하여 상당한 압압탄성으로 압접하게 되어 소경부(3)의 외주면자체도 심파이프(2)의 내면에 확실히 압접되고 또한 노크캡(5)을 캡부(1)에 피우고 떼는 동작을 부드럽게할 수 있다.이상의 설명에서와 같이 본 고안은 고경부(3)와 대경부(4)로 이루여진 노크캡(5)을 캡확(1)의 심파이프(2) 내에 설치하고 상기 소경부(3)로는 수평홈(6)을 형성하며 상기 수평홈(6)과 연장되는 대경부(4) 중간부위로는 장공(66a)을 형성시켜 상기 수평홈(6)과 장공(6a)에 굴곡부(7)와 절곡부(8)를 갖춘 절손심제거핀(9)이 결합되게 하였으므로 특별한 걸림수단이 필요없이 헐거움이 없는 안정된 결합상태를 유지할 수있다.The bent portion 7 is brought into contact with the inner diameter of the seam pipe 2 in a state of slightly protruding upward from the horizontal groove 7 of the small diameter portion 3, and one end of the defibrillation pin 5 is disposed of the suspension 3. From the horizontal groove 6 to protrude toward the holder 10. Therefore, when the knock cap 5 is inserted into the seam pipe 2 as in the above state, the bent portion 7 of the removal pin 9 is seam. The inner wall surface of the pipe 2 is pressed against the inner wall surface with considerable pressure elasticity, so that the outer circumferential surface itself of the small diameter portion 3 is also reliably pressed against the inner surface of the seam pipe 2, and the knock cap 5 is smoked and removed from the cap portion 1. As described above, the present invention provides a knock cap (5) consisting of a high diameter portion (3) and a large diameter portion (4) in the seam pipe (2) of the cap opening (1). The neck portion 3 forms a horizontal groove 6 and the middle portion of the large diameter portion 4 extending with the horizontal groove 6 forms a long hole 66a in the horizontal groove 6 and the long hole 6a.Since the bent core removal pin (9) having the bent portion (7) and the bent portion (8) is coupled, it is possible to maintain a stable coupling state without looseness without the need for a special locking means.
