Description

휴대용 공기 펌프장치Portable air pump unit

제1도 및 제2도는 본 고안 공기펌프의 단면도로서 각 도면은 피스턴의 왕복 작동으로 공기를 펌핑하는 상태는 도시한 것이다.1 and 2 are cross-sectional views of the air pump of the present invention, each of which shows the state of pumping air in the reciprocating operation of the piston.

본 고안은 파이프로 형성한 피스턴 로드를 한손으로 잡고, 다른 한손으로는 실린더를 잡은 다음, 실린더를 왕복 작동시키면 피스턴을 사이에 둔 양 압축실에서 진입된 외기가 번갈아 가면서 압축되어 종래의 1행정으로 펌핑하는 휴대용 펌프에 대하여 같은 힘으로 2배의 공기를 공급하는 휴대용 펌프를 제공코저 하는 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention grabs the piston rod formed of pipe with one hand, the cylinder is held with the other hand, and when the cylinder is reciprocated, the outside air entered from both compression chambers between the pistons is compressed alternately to the conventional one stroke. Providing a portable pump for supplying twice the air with the same force for the pump pumping portable pump to be described in detail by the accompanying drawings as follows.

본 고안은 실린더(1)내에 로드(8)로 왕복 작동시키는 피스턴(13)을 수용하고 그 실린더(1)의 후면과 전면에는 통기공(2)(2')을 뚫을 캡체(3)(3')를 나착하여 각 캡체(3)(3')의 내면에 변판(6)(6')을 장착한 것에 있어서, 피스턴(13)의 주면에 고무링(14)보다 폭이 넓은 링홈(15)을 요설함과 아울러, 그 링홈(15)과 연통되는 관통공(16)을 맞뚫어서 관체로 된 공기공급관(8)과 연통되게 하고, 그 공기공급관 (8)의 선단에는 공기배출공(17')을 뚫은 통상의 아답터(17)을 나착함과 아울러 손잡이(18)을 착설한 것이다.The present invention accommodates a piston (13) for reciprocating with a rod (8) in the cylinder (1) and a cap body (3) (3) for drilling holes (2) (2 ') in the rear and front of the cylinder (1). ') Attached to the inner surface of each cap body (3) (3') and the side plate (6) (6 '), the ring groove (15) wider than the rubber ring (14) on the main surface of the piston (13) ) And the through hole 16 communicating with the ring groove 15 to communicate with the tubular air supply pipe (8), and the air discharge hole (17) at the tip of the air supply pipe (8) In addition to attaching a conventional adapter (17) punched through '), the handle 18 is installed.

미설명부호(4)는 돌축이고, (5)는 통공이며, (7)은 활핀, (9)(10)은 통공, (11)은 홈, (12)는 링판, (A)(B)는 피스턴(13)을 사이에 둔 압축실이다.Unexplained symbol (4) is a stone shaft, (5) is a through hole, (7) is a bow pin, (9) (10) is a through hole, (11) is a groove, (12) is a ring plate, (A) (B) Is a compression chamber with the piston 13 interposed therebetween.

상기와 같이 구성된 본 고안 펌프장치는 이것을 사용할 때 한손으로 손잡이 (18)를 잡고, 다른 한손으로는 실린더(1)의 후축을 잡은 다음, 제1도와 같이 실린더 (1)를 전진 작동시키면 압축실(A)내에 있는 공기가 압축되었는데 따라 고무링(14)이 실린더(1)의 내벽의 마찰에 의하여 도면상에서 링홈(15)의 좌측으로 몰리게 되므로 압축실(A)측의 피스턴 주면에 간격이 생기게 되는 한편, 후축캡(3)의 변판(6)이 내부 압력에 의하여 통기공(2)을 막게 되므로 압축실(A)내에 있는 공기가 상기한 피스턴의 주면 간격과 관통공(16)을 통하여 공기공급관(8)을 따라 배출공(17')으로 방출되는 동시에 타측 압축실(B)의 용적이 늘어나게 되므로 그 압축실(B)내에는 진공력이 조성되어 실린더(1)의 선단부측 캡케(3')의 통기공(2')을 막고 있던 변판(6')이 그 통기공(2')을 열어주므로 압축실(B)내에는 외기가 진입하게 된다.The pump device of the present invention configured as described above uses the handle 18 with one hand, the rear shaft of the cylinder 1 with the other hand, and then moves the cylinder 1 forward as shown in FIG. As the air in A) is compressed, the rubber ring 14 is driven to the left side of the ring groove 15 in the drawing due to the friction of the inner wall of the cylinder 1, so that a gap occurs in the main surface of the piston on the compression chamber A side. On the other hand, since the side plate 6 of the rear axle cap 3 blocks the vent hole 2 by the internal pressure, the air in the compression chamber A is supplied to the air supply pipe through the main surface of the piston and the through hole 16. Since the volume of the other compression chamber B increases while being discharged to the discharge hole 17 'along (8), a vacuum force is generated in the compression chamber B, and the cape 3' at the tip end of the cylinder 1 is formed. ), And the stool (6 ') blocking the vent hole (2') of the opening opens the vent hole (2 ') Chuksil in (B) is the outside air from entering.

다음에 제2도와 같이 실린더(1)를 후측으로 잡아당기면 압축실(B)에 진입되었던 공기가 압축되는 동시에 고무링(14)이 먼저와는 반대로 내벽의 마찰에 의하여 도면상에서 우측으로 이동하여 링홈(15)의 우측벽으로 몰리게 되므로 압축실(B)측 피스턴 주면에 간격이 형성되는 한편, 선단부측 변판(6')이 내부압력에 의하여 통기공(2')을 폐쇄하는 특히 압축실(B)내에 있는 공기가 압축되므로 그 공기가 상기한 피스턴(13)의 주면 간격과 관통공(16)을 통하여 공기공급관(8)을 따라 배출공(17')으로 방출되는 동시에 압축실(A)의 용적이 늘게되어 그 압축실(A)에도 진공력이 조성되므로 통기공(2)을 막고 있었던 변판(6)이 열리게 되는 동시에 그 통기공(2)로부터 외기가 도입된다.Next, as shown in FIG. 2, when the cylinder 1 is pulled to the rear side, the air that has entered the compression chamber B is compressed, and the rubber ring 14 moves to the right side in the drawing by friction of the inner wall as opposed to the first, so that the ring groove Since it is driven to the right side wall of 15, a gap is formed in the main surface of the piston in the compression chamber B side, while the compression chamber B in which the tip side side plate 6 'closes the vent hole 2' by internal pressure. Air is compressed into the discharge hole 17 'along the air supply pipe 8 through the main surface spacing of the piston 13 and the through hole 16. Since the volume increases and a vacuum force is also created in the compression chamber A, the side plate 6 which was blocking the ventilation hole 2 is opened, and the outside air is introduced from the ventilation hole 2.

상기와 같은 작동에 의하여 피스턴(13)을 사이에 둔 압축실(A)(B)에 진입된 외기를 번갈아 가면서 피스턴(13)으로 압축함에 의하여 공기를 계속적으로 공급하는 본 고안 펌프장치는 종래의 1행정만으로 펌핑하는 펌프에 비하여 공기의 공급량을 2배로 증가시키는 효과가 있는 외에 소형으로 견고하고 중량이 가벼운 실용적 펌프를 제공할 수 있다.The pump device of the present invention continuously supplies air by compressing the outside air entered into the compression chamber (A) (B) interposed between the piston (13) by the operation as described above to the piston (13) is conventional In addition to the effect of doubling the amount of air supply compared to the pump pumping only one stroke, it is possible to provide a compact, robust and light practical pump.
