본 고안은 농업용기계 및 각종 중장비에 마련된 윤활부 즉, 베어링부 등에 그리이스를 주유하는 그리이스건(Greace Gun)에 관한 것으로 본인의 선출원 고안인 실용신안등록출원 제 88-719 호 및 제 89-10772 호를 개량한 것에 관한 것이다.The present invention relates to a grease gun for lubricating grease, that is, a bearing part, provided in agricultural machinery and various heavy equipments. It is about improving.

선출원 고안인 제 88-719 호는 본체전반의 압축레베에 의해 펌핑되는 펌핑부, 본체에 그리이스 충전팩을 넣을 수 있는 요흠, 본체 후방에 스프링에 의해 압축되는 밀판과 패킹을 형성하여 그리이스 충전팩 내의 그리이스를 펌핑부로 흡출시키도록 한 구성이고, 이에 개량된 선출원 고안 제 89-10772 호는 극히 짧은 관체형으로하여 내경에 나사부를 갖도록 한 본체, 본체 전방에 작동레버에 의해 작동되는 공지의 펌핑부, 봉체의 지지대에 손잡이를 형성한 연결관부, 그리이스를 충전하고 컵형패킹으로 마감한 그리이스 충전팩을 연결관부에 결합하고, 연결관부는 본체에 나사조립하여서 구성된 것으로, 전자의 경우, 하나의 그리이스 충전팩을 완전히 사용한후 재차 교환 사용할 수 있는 잇점은 있으나 그에 따라 구조가 복잡하고 기존의 그리이스펌프에 혼용하여 사용하기가 곤란하였으며 본체 후방에 형성된 스프링의 탄성이 오랜사용으로 인해 약해지게 되어 작동이 원활치 못한 문제점이 발생할뿐 아니라, 손잡이 봉이 후방에 위치되어져 작동되므로 누유의 위험이 발생할수 있는 문제가 있다.No. 88-719, which is a prior application, forms a pumping part pumped by a compression lever of the main body, a recess into which a grease filling pack can be placed, and a compact plate and packing compressed by a spring at the rear of the main body to form grease in the grease filling pack. Designed to be sucked out by the pumping part, the improved prior application No. 89-10772 is a very short tubular body with a screw in the inner diameter, the pumping part, a known pump operated by the operation lever in front of the body, The grease filling pack, which fills the handle with the handle on the support base, is filled with grease and the cup-type packing is finished.The grease filling pack is coupled to the connector and the connector is screw-assembled to the main body. There is an advantage that can be exchanged again but accordingly the structure is complicated and the And was difficult to use the spring elasticity is formed on the main body rear is weakened due to long use, as well as result in failure wonhwalchi the operating problems, the handle bar is so operated been located at the rear, there is a problem that can occur is a risk of oil leakage.

또한 후자의 경우는 그리이스 충전팩과 기존의 그리이스 통을 혼용하여 사용할수 있는 잇점과 전고안에 비해 부품수가 적게드는 등의 잇점은 있으나 이 역시 그 구조가 복잡하여 그리이스 충전팩만을 사용키 위한 구조로는 부적합할뿐 아니라 피스톤이 실린더내에서 그리이스를 흡입 또는 배출 시키는 펌핑작동 스트로크가 크기 때문에 펌핑 작용 및 흡입, 압출 상태가 원활치 못하여 그리이스 주입시간이 다소 지연되는 등의 문제가 있었던 것이다.In the latter case, there are advantages such as the use of a grease charge pack and a conventional grease container, and the number of parts is smaller than the previous draft. However, this structure is also complicated and it is not suitable as a structure for using only a grease charge pack. In addition, since the pumping stroke of the piston sucks or discharges the grease in the cylinder is large, the pumping action, suction, and the extrusion state is not smooth, so that the grease injection time is somewhat delayed.

따라서, 본 고안은 상기한 선 고안에서의 문제점을 감안 하여 그리이스 충전팩에 전용토록 한 것으로 하나의 그리이스 충전팩을 별도의 중간연결 매개체 없이 직접본체에 연결하여 쉽게 교체 사용토록 한 것이며 피스톤의 작동범위가 크지않아도 효과적인 펌핑작동으로 흡입, 압출 작용이 원활하도록 구조를 개설한 것인바, 이와같은 본 고안의 구성 및 작용효과를 첨부도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention is dedicated to the grease charging pack in consideration of the problems in the above-described design, it is easy to replace and use one grease charging pack directly to the main body without a separate intermediate connection medium and the operating range of the piston is not large Even if it is an effective pumping operation to open the structure so that the suction, extrusion action smoothly, the configuration and effect of the present invention described in detail based on the accompanying drawings as follows.

본체(1)의 수직형 실린더(2)에 피스톤(3)을 내장하고 본체 상단의 링크(4)와 연결한 작동레버(5)에 피스톤(3)을 연결하여 작동레버(5)의 승강작동에 의해 피스톤(3)이 펌핑작동을 하게하며 본체후단에 그리이스 충전팩(6)을 결합한 것에 있어서, 본체(1)상단후면에 T형 빔형상의 지지대(7)를 본체와 일체로 형성하여 그리이스충전팩(6)의 안정된 지지력을 갖게 하고 펌핑작업시 후단손잡이(8)를 이용하여 취급이 간편하도록 하며, 본체(1)의 실린더(2)하단에 흡입구(9)와 압출구(10)를 수평상으로 일치되게 설치하여 각각의 내측에 보울밸브(11) (12)를 설치하고 흡입구(9)에는 체결관(13)을 설치하여 그리이스충전팩을 직접 연결접속할수 있게 한 것이다.Lifting operation of the actuating lever 5 by connecting the piston 3 to the actuating lever 5 in which the piston 3 is built into the vertical cylinder 2 of the main body 1 and connected to the link 4 at the upper end of the main body 1. The piston (3) to the pumping operation by coupling the grease filling pack (6) to the rear end of the main body, the T-beam-shaped support (7) formed on the upper and rear surfaces of the main body (1) integrally with the main body and grease filling pack (6) to have a stable supporting force and to facilitate the handling by using the rear end handle (8) during the pumping operation, the inlet (9) and the extrusion port (10) horizontally in the lower part of the cylinder (2) of the main body (1) By installing in accordance with the installation of the bowl valve (11) (12) in each of the inlet and the inlet (9) by installing a fastening pipe 13 is to enable the connection of the grease charge pack directly connected.

도면중 미설명 부호 14는 컵형 패킹이다.In the figure, reference numeral 14 denotes a cup-shaped packing.

이와같이 구성한 본 고안은 본체(1)의 후방에 마련된 체결관(13)의 암나사부에 그리이스 충전팩(6)의 전면체결부를 결합한 상태에서 제 2b 도에서와 같이 작동레버(5)를 상측으로 들어올리면 그리이스 충전팩(6)내의 그리이스가 실린더(2)내부의 진공흡입력에 의하여 실린더(2)내부로 흡입되며 이때는 흡입구 쪽의 보울밸브(11)는 열리는 반면에 압출구쪽의 보울밸브(12)는 막히게 되어 그리이스(7)가 실린더(2)내로 흡입된다.The present invention constituted as described above raises the operating lever 5 upward as shown in FIG. 2B in a state in which the front fastening portion of the grease filling pack 6 is coupled to the female screw portion of the fastening tube 13 provided at the rear of the main body 1. The grease in the grease filling pack (6) is sucked into the cylinder (2) by the vacuum suction input inside the cylinder (2). At this time, the bowl valve (11) of the inlet port is opened while the bowl valve (12) of the extrusion port is blocked. The grease 7 is sucked into the cylinder 2.

이상태에서 제 2a 도에서와 같이 작동레버(2)를 하방으로 눌러주면 실린더(2)내의 피스톤(3)이 하강되면서 압축력을 가하기 때문에 흡입구 쪽의 보울밸브(11)는 닫히고 압출구쪽의 보울밸브(12)는 열리면서 그리이스가 압출공급되는 것이다.In this state, when the operating lever 2 is pushed downward as shown in FIG. 2a, the piston 3 in the cylinder 2 is lowered to apply a compressive force. Therefore, the bowl valve 11 on the inlet side is closed and the bowl valve on the extrusion port side ( 12) is opened and grease is extruded.

이와같은 펌핑작동이 반복됨에 의해서 그리이스는 연속적으로 압축되어 각종 중장비등의 윤활부에 주입하도록 한 것이다.By repeating such a pumping operation, the grease is continuously compressed and injected into the lubrication part of various heavy equipment.

또한 작동레버(5)의 펌핑작동에 의해 실린더(2)내에는 진공 흡인력이 발생하여 그리이스 충전팩(6)내의 그리이스가 상기 실린더(2)내부로 흡입됨과 동시에, 컵형패킹(14)은 흡입력에 의해 전방으로 전진되어 그리이스를 전방으로 완전히 밀어낼수가 있는 것이다.In addition, a vacuum suction force is generated in the cylinder 2 by the pumping operation of the operating lever 5, and the grease in the grease filling pack 6 is sucked into the cylinder 2, and the cup-type packing 14 is sucked by the suction force. Advance forward and push the grease completely forward.

이와같이된 본 고안은 펌핑부를 일체로 형성한 본체(1)의 실린더(2)하단과 일직선상에 흡입구(9)와 압출구(10)를 형성하되 각각에 보울밸브(11) (12)를 설치하므로서 그리이스의 흡입과 압출작용을 작동레버(5) 및 피스톤(3)의 짧은 스트로크 즉, 좁은 범위의 작동으로도 쉽게 주입할 수 있는 것이며, 체결관(13)에 충전팩(6)을 직접 착탈시킬수 있게 하므로서 충전팩(6)을 완전사용후 그 즉시 손쉽게 교환하여 사용할 수 있게 한 것이며 지지대(7)를 본체(1)와 일체로 형성하므로서 유동없는 지지력과 견실한 지탱력에 의해 펌핑 작업에 힘이들지 않는 효과가 있으며, 구조가 간단하고 부품수가 작게들어 원가절감등의 효과를 기할수 있는 등의 잇점이 있는 유용한 고안인 것이다.In this way, the present invention forms a suction port 9 and an extrusion port 10 in a line with the lower end of the cylinder 2 of the main body 1 in which the pumping part is integrally formed. Therefore, the suction and extrusion action of the grease can be easily injected even with a short stroke of the operating lever 5 and the piston 3, that is, a narrow range of operation, and the filling pack 6 can be directly detached from the fastening pipe 13. This makes it possible to easily replace the filling pack (6) immediately after full use and to form the support (7) integrally with the main body (1), so that the pumping work is difficult due to the support without a flow and a strong support force. It is a useful design that has the advantage of not having an effect, such as the structure is simple and the number of parts is small, which can reduce the cost.

또한 본 고안은 수동레버에 의한 수동펌핑 방식이지만 이에 한정하는 것이 아니고 전동 및 에어펌프 방식에도 적용설치할 수 있는 것이며 효과는 동일한 것이다.In addition, the present invention is a manual pumping method by a manual lever, but is not limited thereto, and can be applied to an electric and air pumping method, and the effect is the same.
