Description

One-touch coupler for nylon pipes {An one touch coupler for nylon pipe}

본 발명은 각종 산업기계 또는 가전제품에서 공기나 액체를 이동시키기 위해 구성되는 나일론 관체를 연결하는 원터치 연결구에 관한 것이다.The present invention relates to a one-touch connector for connecting a nylon tube configured to move air or liquid in various industrial machines or home appliances.

종래의 나일론 관체용 연결구는 도 6에서 도시한 것과 같이 본체(50)의 일측에는 홈(51)을 형성하고 닛블(52)에는 돌환부(53)를 형성해 억지끼움하였고 또 본체(50)의 타측에는 받침링(54)과 컬러(55)와 슬리브(56)를 결합해 구성되어 있다.Conventional nylon tubular connector has a groove 51 on one side of the main body 50 and a projection 53 on the nib 52 to be tightly pressed as shown in FIG. On the side, the support ring 54, the collar 55, and the sleeve 56 are combined and comprised.

상기의 구성에서 본체(50)는 합성수지이고 닛블(52)과 받침링(54), 컬러(55)가 황동으로 되어 있는데, 이와 같은 경우에 닛블(52)과 컬러(55)를 본체(50)와 결합할때 억지끼움을 해야하기 때문에 조립상 어려움이 있고 뿐만 아니라 억지끼움시 상대적으로 약한 재질의 본체(50)가 쉽게 파손될수 있고 조립시 본체의 홈과 닛블의 돌환부가 정확하게 끼워지지 않은 것을 사용할 경우에는 조립부분에서 내용물이 새거나 본체의 내경에 나사홈을 만들면서 풀어지는 사례가 있고, 또 닛블(52)과 받침링(54), 컬러(55) 등 부품이 황동이기 때문에 절삭가공으로만 생산이 가능하고 또한 외부로 노출되는 닛불이나 컬러는 공기와 접촉해 산화되는 것을 방지하기 위해 도금이나 코팅처리를 필수적으로 해야만 하였다.In the above configuration, the main body 50 is made of synthetic resin, and the nibble 52, the support ring 54, and the color 55 are made of brass. In this case, the nibble 52 and the color 55 are made of the main body 50. It is difficult to assemble because it must be fitted when combined with the main body. In addition, the body 50 of relatively weak material can be easily damaged during assembly, and the groove of the body and the protrusion of the nibble are not fitted correctly. In some cases, the contents are leaked from the assembly or loosened while making a screw groove in the inner diameter of the main body.The parts such as the nibble 52, the support ring 54 and the color 55 are made of brass, so they are produced only by cutting. This possible and externally exposed nitbull or color had to be plated or coated to prevent oxidation in contact with air.

따라서 조립과 절삭가공 등에 따른 생산과정이 비능률적이고 조립 및 사용시 본체의 파손률이 높고, 생산설비와 공간확보에 의한 시설비용이 많이 소요되는 등 문제점으로 인하여 품질은 낮고 생산원가는 높은 원터치 연결구가 제공될 수밖에 없었다.As a result, the production process due to assembly and cutting process is inefficient, the breakage rate of the main body is high when assembling and using, and the facility cost is high due to the production equipment and space. There was no choice but to be.

이와 같은 문제점을 해결하기 위해 각 부품을 사출물로 바꾸면서 초음파 용접을 한 원터치 연결구가 있으나 부분적으로 움직일 수 없기 때문에 사용상 연결구를 정렬하기에 불가능한 등의 문제점이 있었다.In order to solve this problem, there is a one-touch connector made by ultrasonic welding while replacing each part with an injection molding, but there is a problem such that it is impossible to align the connector in use because it cannot be partially moved.

본 발명은 상기한 제반 문제점을 해결하기 위해 본체와 닛블, 슬리브와 컬러 및 컬러받침링구를 합성수지로 형성하면서 본체에 결합되는 닛블과 컬러에 요입부를 형성하고 여기에 황동으로 된 고정링구를 끼운 다음 본체에 결합하며. 또한 컬러에 컬러받침링구를 끼움한 것으로서 생산 및 조립이 용이하고 저렴한 원가로 품질이 우수한 제품을 대량으로 생산할 수 있도록 하는데 소기의 목적하는 바가 있다.The present invention forms a concave portion in the nibble and color coupled to the body while forming the body and the nibble, sleeve and color and the color support ring to the body to solve the above problems, and then put a fixing ring made of brass thereon To combine. In addition, as the color support ring is inserted into the color, it is easy to produce and assemble, and it is intended to enable the production of high quality products in large quantities at low cost.

본 발명의 나일론 관체용 원터치 연결구에 관한 바람직한 구성을 이하 부수되는 도면과 관련하여 상세히 설명하면 다음과 같다.The preferred configuration of the one-touch connector for nylon tube of the present invention will be described below in detail with reference to the accompanying drawings.

원터치 연결구는 I형, Y형, L형 등 여러 형상으로 구성될 수 있으며, 일측에는 닛블이 타측에는 나일론 관체가 결합된다.One-touch connector can be configured in various shapes, such as I-type, Y-type, L-type, the nibble on one side and the nylon tube is coupled to the other side.

상기와 같은 여러 형상의 원터치 연결구를 형성함에 있어서, 합성수지로 본체(1)과 니시블(2), 슬리브(3)와 컬러(4) 그리고 컬러받침링구(5)를 합성수지로 형성되고 관체 협지링(6)은 스텐레스, 고정링구(7)는 황동으로 형성되어 있다.In forming the one-touch connector of various shapes as described above, the body 1 and the nibble (2), the sleeve (3) and the color (4) and the color support ring (5) is formed of synthetic resin and the tube clamping ring (6) is stainless, and the fixing ring (7) is made of brass.

본체(1)의 내주연 양측에 요홈(8)(9)을 환설하고 닛블(2)에 요입부(10)를 형성해 개구부(11)와 돌환부(12)가 형성된 고정링구(7)를 끼우고 다시 본체(1)의 일측에 결합하되 돌환부(12)가 요홈(8)에 끼움되게 하였고, 본체(1)의 나일론 관체 삽입구 쪽에 결합되는 컬러(4)는 외주연을 경사지게 하고 또 요입부(13)를 형성해 개구부(11)와 돌환부(12)가 형성된 고정링구(7)를 끼우고 내주연에는 요홈(14)을 형성해 돌환부(15)가 형성된 컬러받침링구(5)를 결합하고 슬리브(3)와 함께 본체(1)에 결합하여 구성된 것이다.The grooves 8 and 9 are rounded on both sides of the inner circumference of the main body 1, and the recesses 10 are formed in the nibble 2 to sandwich the fixing ring 7 having the opening 11 and the projection 12. And then coupled to one side of the main body (1), but the projection 12 is fitted into the groove (8), the color (4) coupled to the nylon tube insert side of the main body 1 inclined the outer periphery and indentation (13) to form a fixing ring (7) having an opening (11) and the projection 12 is formed, the inner periphery formed grooves (14) to combine the color bearing ring (5) formed with the projection (15) It is configured to be coupled to the body 1 together with the sleeve (3).

상기의 고정링구(7)를 구성하는 돌환부(12)는 두줄로 할 수 있고 또 개구부(11) 없이 여러개의 절개홈(16)을 형성할 수도 있다.The projections 12 constituting the fixing ring 7 may be formed in two lines, and may form a plurality of cutout grooves 16 without the opening 11.

도면의 미설명 부호 20은 오링, 21은 나일론 관체를 표시한 것이다.In the drawings, reference numeral 20 denotes an O-ring and 21 denotes a nylon tube.

이와 같이 구성된 본 발명의 나일론 관체용 원터치 연결구에 관한 작용을 상세히 설명하면 다음과 같다.Referring to the action related to the one-touch connector for nylon tube of the present invention configured as described above in detail as follows.

본체(1)에 닛블(2)을 결합할 시에 요입부(10)에 끼움된 고정링구(7)가 개구부(11)의 작용에 의해 순간적으로 오무러지면서 원활하게 결합되는 동시에 요홈(8)에 돌환부(12)가 끼움되고 또 본체(1)의 나일론 관체 삽입구 쪽에 결합되는 컬러(4) 역시 요입부(13)에 끼움된 고정링구(7)가 개구부(11)의 작용에 의해 순간적으로 오무러지면서 원활하게 결합되는 동시에 요홈(9)에 돌환부(12)가 끼움되어 조립되는 것으로서, 각종 산업기계 또는 가전제품에서 공기나 액체를 이동시키기 위해 구성되는 나일론 관체(21)를 연결하는 곳에 주로 사용된다.When coupling the nibble 2 to the main body 1, the retaining ring 7 fitted to the inlet 10 is instantaneously crushed and smoothly engaged by the action of the opening 11 and at the same time the groove 8 The collar 4, which is fitted with the projection 12 and is coupled to the nylon tube insertion hole side of the main body 1, also has a fixing ring 7 fitted to the concave inlet 13 by the action of the opening 11. At the same time, the protrusions 12 are fitted into the grooves 9 and assembled together, and the nylon pipes 21 are formed to move air or liquid in various industrial machines or home appliances. Mainly used.

상기의 사용과정에서 닛블(2)을 각종 산업기계나 가전제품에 고정설치하고 나일론 관체(21)와 연결된 본체(1)를 움직이게 되면 닛블(2)과 고정링구(7)와 본체(1) 사이에 슬립현상이 생겨 움직임이 원활하고 닛블(2)과 본체(1)가 쉽게 빠지지 않게 되는 것이며, 본체(1)의 타측에 결합된 나일론 관체(21)를 빼내고자 할때는 슬리브(3)를 밀어주면 슬리브(3)가 내측으로 들어가면서 관체 협지링(6)을 벌려주고 나일론 관체(21)를 당겨서 빼낼 수 있는 것이다.In the above use process, when the nibble 2 is fixedly installed on various industrial machines or home appliances and the main body 1 connected to the nylon tube 21 is moved, between the nibble 2 and the fixing ring 7 and the main body 1 When the slip phenomenon occurs, the movement is smooth and the nibble 2 and the main body 1 do not fall out easily. When the nylon tube 21 coupled to the other side of the main body 1 is pulled out, the sleeve 3 is pushed. As the sleeve 3 enters the inner side, the tube clamping ring 6 may be opened and the nylon tube 21 may be pulled out.

이상과 같은 본 발명은 본체와 닛블, 컬러와 컬러받침링구가 합성수지로 사출되었고 고정링구가 탄성을 가지고 있기 때문에 각 부품 생산 및 조립이 용이함은 물론, 닛블과 본체가 움직이도록 되어 있어 닛블 조립 및 정렬시 편리함을 더할수 있을뿐만 아니라 최소한의 생산설비와 설치공간으로 품질이 우수한 제품을 대량생산 하면서 생산원가를 절감할 수 있는 효과가 있다.In the present invention as described above, since the main body and the nibble, the color and the color support ring are injected into the synthetic resin, and the fixing ring has elasticity, each part is easy to produce and assemble, as well as the nibble and the main body to move and assemble and align the nibble. In addition to the convenience of time, it is possible to reduce production costs while mass-producing high quality products with minimal production equipment and installation space.
