Description
제1도는 본 고안의 일부를 절개한 분해 사시도.1 is an exploded perspective view of a portion of the present invention cut.
제2도는 본 고안의 조립 종단면도.2 is an assembly longitudinal cross-sectional view of the present invention.
본 고안은 펌프동체의 실린더부의 내주면에 요입부를 형성하여 이에 별도의 실린더관을 수납사용토록 한 수동식 펌프에 관한 것이다.The present invention relates to a manual pump to form a recess in the inner circumferential surface of the cylinder portion of the pump body to accommodate the use of a separate cylinder tube.
종래에는 펌프동체를 주물성형한 후에 실린더부의 내주면을 선반에 의해 정밀하게 가공사용 하였기 때문에 선반작업에 따른 정밀가공의 번거로움과 수분의 개재에 따른 철의 산화작용으로 인해 매우 비위생적인 문제점을 내포하고 있었으며 선반 작업에 의한 정밀가공을 하였다하나 그 가공면이 고루지 못하여 이에 접동되는 펌프피스톤의 패킹이 쉬이 마모되어 그 밀폐도가 저하되므로 펌프피스톤의 흡상력이 약화되어 수동식 펌프로서의 제구실을 상실하게 되는 폐단이 있었다.In the past, since the inner peripheral surface of the cylinder part was precisely processed by lathe after casting the pump body, it has a very unsanitary problem due to the cumbersome work of lathe work and the oxidation of iron due to the presence of moisture. Although the precision processing by lathe work was performed, the processing surface was not uniform and the packing of the sliding piston was easily worn and the sealing degree was lowered. Therefore, the suction force of the pump piston was weakened and the control room as a manual pump was lost. There was a dissolution.
본 고안은 이와 같은 종래의 폐단을 해소하기 위해 펌프동체의 실린더부에 별도의 이물질로 성형된 실린더관을 수납사용케 한 것으로 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.The present invention is to accommodate the use of a cylinder tube formed of a separate foreign material in the cylinder portion of the pump body to solve such a conventional closed end described in detail according to the accompanying drawings as follows.
흡상관(1)을 후렌치(2)(2′)로서 펌프동체(3)에 연결하여 손잡이(4)의 작동에 따라 펌프피스폰(5)을 상하로 동작케 한 통상의 수동식 펌프에 있어서, 펌프동체(3)의 실린더부(3′)의 내주면에 단턱(6′),(6〃)이 형성된 요입부(6)를 형성하여 이에 걸림턱(7′)이 형성된 별도의 실린더관(7)을 수납사용케 하여서 됨을 특징으로 한 것으로 도면중 미설명부호 8은 패킹이다.In a conventional manual pump in which the suction pipe (1) is connected to the pump body (3) as a wrench (2) (2 '), and the pump piston (5) is operated up and down according to the operation of the handle (4). In addition, a separate cylinder tube having a recessed jaw (7 ') is formed on the inner circumferential surface of the cylinder (3') of the pump body (3) by forming stepped portions (6 '), (6'). 7) is characterized in that the storage and use, and reference numeral 8 in the drawing is a packing.
본 고안을 실시함에 있어 펌프동체(3)의 요입부(6)와 별도의 실린더관(7)은 각기 1공정에 의한 주물로서 사출 성형하되 실린더관(7)의 재질은 활면성(滑面性)이 양호한 것으로 한다.In carrying out the present invention, the indentation part 6 of the pump body 3 and the cylinder tube 7 separate from each other are injection molded as a casting by one step, but the material of the cylinder tube 7 is smooth. ) Is good.
이와 같이 된 본 고안은 별도의 실린더관(7)을 펌프동체(3)의 요입부(6)에 수납사용케 된 것으로 실린더관(7)의 걸림턱(7′)이 요입부(6)의 단턱(6″)에 괘지되게 내삽하면 실린더관(7)의 상면은 자동적으로 단턱(6′)에 괘지되므로 이에 패킹(8)이 개재된 흡상관(1)의 후렌치(2)를 대접 체결하면 실린더관(7)은 펌프 동체(3)의 요입부(6)에 긴밀하게 밀착되어 견고하게 수납된다. 그리고 후렌치(2)(2′)의 체결보울트를 해체하면 간편용이하게 실린더관(7)만을 교체 사용할 수가 있다.According to the present invention, a separate cylinder tube 7 is housed in the recess 6 of the pump body 3 so that the locking jaw 7 'of the cylinder tube 7 is formed in the recess 6 of the pump body 3. When interpolated to the step 6 ″, the upper surface of the cylinder tube 7 is automatically hanged on the step 6 ', so that the flange 2 of the suction tube 1 with the packing 8 interposed therebetween is treated. The lower surface cylinder tube 7 is in close contact with the recess 6 of the pump body 3 and is stored firmly. When the fastening bolts of the trenches 2 and 2 'are dismantled, only the cylinder tube 7 can be replaced and used easily.
따라서 본 고안은 펌프동체의 실린더관만을 간편 용이하게 교체사용할 수가 있으므로 종래 재래식 펌프의 난문제를 완전히 배제할 수 있고 펌프의 사용수명을 장기화할 수 있는 잇점이 있다.Therefore, the present invention can simply and easily replace only the cylinder tube of the pump body can completely eliminate the problem of the conventional conventional pump and has the advantage of prolonging the service life of the pump.
