본 고안은 샤프펜슬의 녹크(KNOCK) 장치에 관한 것으로, 특히, 필심튜우브에 녹크를 끼울때 접촉면적을 넓혀 견고하게 끼워져 고무캡을 벗길때 녹크가 불필요하게 빠지는 것을 방지하며, 필관의 굵기에 구애없이 사용할 수 있도록 고안된 것이다.The present invention relates to a KNOCK device of a mechanical pencil, and in particular, to expand the contact area when inserting the knock in the fill tube, it is firmly inserted to prevent the knock from falling out unnecessarily when peeling off the rubber cap, It is designed to be used without regard.

종래의 샤프펜슬에는 필심튜우브 후단에 녹크를 끼우되, 그 전체가 필관내부에 끼워지도록 된 것(대한민국 실용신안 공고번호 제 84-1765호)이 있으나, 필심 튜우브와 녹크의 결합은 녹크내면에 돌출된 다수개의 돌기부분과 접촉된 것이어서 사용빈도가 많아지면서 마모되면 고무캡을 벗길때 불필요하게 빠져나와 사용에 불편이 있었고, 녹크에 형성된 고무캡받침턱 부분이 필관내부에 끼워지는 것이어서 필관은 이에따라 불필요하게 굵어져야만 하는 제작상의 문제점이 있었다.Conventional mechanical pencils have a knock on the rear end of the pen tube, but the whole is inserted inside the tube (Korean Utility Model Publication No. 84-1765), but the combination of the pen tube and the knock is on the inner surface of the knock. It was in contact with a number of protruding protrusions, so when the frequency of use increased, it was inconvenient to use when the rubber cap was removed, and the rubber cap support jaw formed on the knock was inserted in the pen tube. There was a manufacturing problem that had to be unnecessarily thick.

본 고안에서는 이상과 같은 종래 문제점을 해결하기 위하여 필심튜우브에 끼워지는 녹크의 일부인 삽입관체부분에 탄성을 주어 전체면이 접촉 탄압되어 견고하게 끼워지도록 하고, 고무캡받침턱 부분은 필관외부로 노출시켜 필관의 굵기에 구애없이 제작하도록 한 것이다.In the present invention, in order to solve the conventional problems as described above, by giving elasticity to the insertion pipe part which is a part of the knock inserted into the fill core tube, the entire surface is pressed under pressure so that it is firmly fitted, and the rubber cap support jaw is exposed to the outside of the pipe tube. It is to be made regardless of the thickness of the pen.

이를 첨부된 도면에 의하여 그 구성을 상세히 설명하면 다음과 같다.This configuration will be described in detail with reference to the accompanying drawings.

필심튜우부(1)에 고무(2)가 상단에 끼워진 녹크93)를 끼워서 되는 샤프펜슬의 녹크장치에 있어서, 녹크(3)의 하부에 필심튜우브삽입관(4)을 길게 형성하되, 그 외주벽에 길이방향으로 한개 또는 다수의 종절개홈(5)을 형성하여 내경이 신축되도록 하고, 그 내경은 필심튜우브(1) 외경보다 약간 작게 형성하여 착용시 빡빡하게 끼워지도록 하며, 필심튜우브삽입관(4) 상부에는 녹크(3)의 작동거리(X)를 두고 그 위에 고무캡 받침턱(6)을 형성한 구조이다.In the mechanical pencil knocking device in which the knock core 93 having the rubber 2 inserted at the upper end thereof is inserted into the pen core tube 1, the pen core tube inserting tube 4 is formed long in the lower portion of the knock tube 3, One or more longitudinal incisions 5 are formed in the outer circumferential wall so that the inner diameter is stretched, and the inner diameter is slightly smaller than the outer diameter of the pilsim tube 1 so that it fits tightly when worn. The upper portion of the woofer insertion tube 4 has a working distance (X) of the knock (3) is formed on the rubber cap support jaw (6) thereon.

도면중 미설명 부호 7은 고무캡, 8은 필관, 9는 소재핀의 예시이다.In the figure, reference numeral 7 is a rubber cap, 8 is a pipe tube, 9 is an example of a material pin.

본 고안 실시에 있어서 필심튜우브삽입관(4)의 입구(10) 부분은 크고 상단에 안내경사면(11)을 형성하여 필심튜우브(1)를 끼우기 편리하도록 구성한다.In the implementation of the present invention, the inlet portion 10 of the fill tube insertion tube 4 is large and is formed so as to conveniently fit the fill tube (1) by forming a guide inclined surface 11 at the top.

이상과 같은 본 고안 녹크장치는 필심튜우브(1)의 상부 외면전체가 필심튜우브삽입관(4) 내면에 빡빡하게 끼워지면서 종절개홈(5)으로 신축성이 부여된 탄성으로 견고하게 끼워져 있어 종래의 돌기만으로 접촉된 것에 비해 매우 견고하므로 고무캡(7)을 벗길때 불필요하게 녹크(3)가 빠지는 것이 방지되며, 고무캡받침턱(6)은 팔관(8) 상단에서 녹크동작거리(x)를 두고 그 위에 형성한 것이어서 종래의 필관(8)내부의 받침턱이 끼워져 있는 경우와는 달리 제작시 필관(8)의 굵기에 따라 구애가 없으므로 불필요하게 필관(8)이 받침턱(6)이 튀어나온 만큼 굵어지는 문제점도 방지하여 임의로 제작할 수 있는 효과가 있다.The knock device of the present invention as described above is firmly fitted with elasticity given elasticity to the longitudinal cutout groove 5 while the entire upper outer surface of the fill core tube 1 is tightly fitted to the inner surface of the fill tube 2. Compared with the conventional protrusions, it is very firm, so that the knock 3 is prevented from being unnecessarily removed when the rubber cap 7 is removed, and the rubber cap support jaw 6 has the knock operation distance x from the upper end of the arm tube 8 Unlike the case where the basement jaw inside the conventional pipe tube 8 is inserted therein, the pipe tube 8 is unnecessary due to the thickness of the pipe tube 8 at the time of manufacture. It also has the effect of preventing the problem of thickening as it protrudes and can be produced arbitrarily.
