Description

정수라인의 튜브 압입 피팅구조{Tube fitting structure of water purification line}Tube fitting structure of water purification line

본 발명은 정수기나 냉장고와 같은 제품의 정수라인에서 유로를 형성하는 튜브를 기구물에 연결하기 위한 피팅구조에 관한 것으로, 더욱 상세하게는 튜브가 피팅된 상태에서 압입 고정되어 외력이 작용하더라도 회전되지 않고 누수를 방지하도록 한 것이다.The present invention relates to a fitting structure for connecting a tube forming a flow path in a water purification line of a product such as a water purifier or a refrigerator to an appliance, and more particularly, the tube is press-fitted and fixed in a fitted state so that it does not rotate even when an external force is applied. This is to prevent leakage.

일반적으로 정수기나 냉장고와 같은 제품은 물을 정수한 이후에 배출하기 위하여 제품 내부에 정수라인이 형성되는 것으로, 물을 공급하기 위한 워터밸브를 포함하여 다양한 종류의 필터가 장착되어 물이 필터를 경유하면서 정수가 이루어진다.In general, in products such as water purifiers and refrigerators, a water purification line is formed inside the product to discharge water after purification. Purification is done while

이러한 정수라인에는 워터밸브, 필터, 기타 기구물, 뷰브 등을 서로 연결하기 위하여 여러 부분에 피팅구조가 적용되는데, 이러한 피팅구조가 취약할 경우 누수가 발생하는 문제가 있다.In such a water purification line, a fitting structure is applied to various parts to connect a water valve, a filter, other equipment, a bub, etc. to each other, but when the fitting structure is weak, there is a problem that water leakage occurs.

특히, 정수기나 냉장고와 같은 제품에는 매우 많은 부속품이 내장되고 각각의 부속품들은 튜브로 연결되기 때문에 튜브 피팅부위가 매우 여러 부위에 연결될수밖에 없다.In particular, since many accessories are built-in in products such as water purifiers and refrigerators, and each accessory is connected by a tube, the tube fitting part has no choice but to be connected to many parts.

튜브 피팅의 가장 일반적인 구조는 튜브삽입관에 튜브를 끼워 장착한 상태에서 조임을 위한 캡을 가압함으로써 원터치로 피팅이 이루어지는 피팅구조를 채용하고 있는 것으로, 최근에는 제품의 품질향상을 위해서 누수테스트 단계에서 더 높은 기밀성이 요구된다.The most common structure of tube fittings adopts a fitting structure in which one-touch fitting is performed by pressing the cap for tightening while the tube is inserted into the tube insertion tube. Higher confidentiality is required.

그런데 누수테스트 단계에서 기밀성을 확보하였다 하더라도 현장에서 튜브 피팅을 하고 분리 체결하는 과정에서 누수가 발생될 가능성이 매우 높다.However, even if airtightness is secured in the leak test stage, there is a very high possibility that water leakage may occur in the process of fitting and separating the tube in the field.

즉, 현장의 설치 상황에 따라서, 또는 점검을 위하여 튜브를 분리한 후 다시 체결하는 상황에서 체결력이 저하되어 누수가 발생하거나, 또는 튜브 연결된 상태의 기구물을 움직일 때 튜브가 회전하면서 밀폐력이 약화되면서 튜브 연결부위에서 누수가 발생할 수 있다.That is, depending on the installation situation at the site, or when the tube is disconnected and then re-tightened for inspection, leakage occurs due to a decrease in the fastening force, or when the tube is rotated and the sealing force is weakened when moving the equipment in the connected state, the tube Leakage may occur at the connection point.

특히, 위와 같은 문제를 방지하기 위해서는 튜브와 바디를 빡빡하게 끼워서 결합을 해야 하기 때문에 튜브삽입관의 외경과 튜브의 내경을 압입 고정이 이루어질 수 있도록 과도하게 설계가 이루러지고, 이로 인하여 피팅부의 결합이 어려워서 작업성이 저하되는 문제가 있다.In particular, in order to prevent the above problem, since the tube and the body must be tightly coupled to each other, the design is made excessively so that the outer diameter of the tube insertion tube and the inner diameter of the tube can be press-fitted and fixed. This is difficult, and there is a problem in that workability is lowered.

또한, 이렇게 강제 끼움으로 조립되는 경우에는 유지보수를 위하여 피팅 연결부를 해체하기가 거의 불가능하고, 해체하였다 하더라도 그 과정에서 튜브삽입관 또는 바디가 손상되는 문제가 있으며, 손상된 상태로 다시 재조립이 이루어질 경우 튜브연결부위가 헐거워져 누수가 발생하게 되는 문제가 있다.In addition, when assembled by force fitting in this way, it is almost impossible to dismantle the fitting connection for maintenance, and even if it is disassembled, there is a problem that the tube insertion tube or the body is damaged in the process, and reassembly can be performed in a damaged state. In this case, there is a problem that the tube connection part becomes loose and leaks occur.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 튜브 피팅부위에서 튜브삽입관과 튜브의 끼움 조립이 용이하게 이루어지면서도 이음연결시키는 결합부위에의 튜브 회전을 방지하도록 하여 튜브 피팅부위에 움직임이 발생하더라도 튜브가 유동되지 않고 체결상태를 안정적으로 유지하여 누수가 방지되도록 한 것이다The present invention is to solve the above problems, and while fitting and assembling the tube insertion tube and the tube in the tube fitting portion is made easy, the rotation of the tube in the coupling portion for joint connection is prevented, so that the movement of the tube fitting portion is reduced. Even if it occurs, the tube does not flow and the fastening state is maintained stably to prevent leakage.

상기 목적을 달성하기 위한 기술적 사상으로서의 본 발명은, 정수라인 상에 구비되는 바디와, 상기 바디에 끼워져 정수라인을 구성하는 튜브와, 튜브가 바디에 결합된 상태에서 분리되지 않게 바디에 체결 고정되는 체결캡을 포함하고, 상기 바디에는 튜브삽입부와 캡체결부가 형성되어 튜브삽입부에 튜브가 끼워진 상태에서 체결캡이 조립되며, 상기 체결캡의 내경에는 가압경사면이 형성되어 가압경사면이 튜브 외경을 가압하면서 체결캡의 락킹부가 캡체결부에 걸려 조립이 이루어지는 정수라인의 튜브 압입 피팅구조에 있어서, 상기 튜브삽입부는 튜브삽입관과, 튜브삽입관보다 더 큰 외경을 갖도록 되어 튜브의 내경에 압입되도록 튜브접속부를 형성하고, 튜브삽입관에는 튜브가 끼워진 상태에서 체결캡의 가압경사면에 의하여 튜브가 가압되면서 튜브 회전을 방지하기 위하여 튜브 선단부가 압착되게 돌출 형성되는 튜브압착부를 형성함으로써 튜브가 체결된 상태에서 회전을 방지하고, 조립된 상태를 안정적으로 유지하도록 한 것이다.The present invention as a technical idea for achieving the above object is a body provided on a water purification line, a tube inserted into the body to constitute a water purification line, and the tube is fastened and fixed to the body so as not to be separated in a state in which the tube is coupled to the body. A fastening cap is included, wherein a tube insertion part and a cap fastening part are formed in the body, and the fastening cap is assembled in a state where the tube is inserted into the tube insertion part, and a pressure inclined surface is formed in the inner diameter of the fastening cap, so that the pressure inclined surface is the outer diameter of the tube In the tube press-fitting structure of a water purification line in which the locking part of the fastening cap is caught by the cap fastening part while being pressed and assembled, the tube inserting part has a larger outer diameter than the tube inserting tube and the tube inserting tube so that it is press-fitted into the inner diameter of the tube. The tube is fastened by forming a tube connection part, and forming a tube compression part in which the tube tip protrudes to be compressed to prevent rotation of the tube while the tube is pressed by the pressure inclined surface of the fastening cap in a state where the tube is inserted into the tube insertion tube. It is designed to prevent rotation and maintain the assembled state stably.

본 발명의 정수라인의 튜브 압입 피팅구조에 의하면, 튜브 피팅구조에서 조립 구성품의 추가가 없이 기존의 금형구조를 크게 변경시키지 않고 제작함에도 튜브를 일정깊이로 삽입한 상태에서 튜브가 튜브압착부에 의하여 회전이 방지되면서 바디와 튜브의 결합이 더욱 긴밀히 이루어져 튜브에 외력이 가해지더라도 접속부위의 기밀성을 유지하고 피팅부위에서의 누수를 방지할 수 있다.According to the tube press-fitting structure of the water purification line of the present invention, the tube is inserted into the tube to a certain depth even though the existing mold structure is not significantly changed without the addition of assembly components in the tube fitting structure. As rotation is prevented, the coupling between the body and the tube is made closer, so that even if an external force is applied to the tube, it is possible to maintain the airtightness of the connection part and prevent water leakage from the fitting part.

또한, 피팅구조에서의 기밀성을 향상시킴에도 불구하고 체결공정에서 튜브 결합이 용이하도록 하여 작업시간 단축으로 작업성을 크게 향상시킬 수 있으며, 유지보수를 위하여 캡을 분리할 경우에도 튜브삽입관 또는 튜브가 손상되는 것을 방지하고 부품을 교체할 필요없기 때문에 반복 사용이 가능하고 원가비용을 절감할 수 있는 효과가 있다.In addition, in spite of improving the airtightness in the fitting structure, it is possible to greatly improve the workability by reducing the working time by making it easy to combine the tubes in the fastening process. It prevents damage to the product and eliminates the need to replace parts, so it can be used repeatedly and has the effect of reducing cost.

이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도 1 내지 도 6에 도시된 바와 같이 정수라인 상에 구비되는 바디(100)와, 상기 바디에 끼워져 정수라인을 구성하는 튜브(200)와, 튜브가 바디에 결합된 상태에서 분리되지 않게 바디에 체결 고정되는 체결캡(300)을 포함하여 구성되는 것으로, 상기 바디(100)에는 튜브를 끼워 고정하기 위한 튜브삽입부(120)와, 튜브삽입부(120)의 후단에 형성되어 체결캡(300)이 조립되어지는 캡체결부(140)가 형성되어 튜브삽입부(120)에 튜브(200)를 끼운 상태에서 체결캡(300)을 강제로 가압하여 끼워 체결캡(200)이 조립되는 것이고, 체결캡(300)의 내경에는 가압경사면(320)이 형성되어 가압경사면(320)이 튜브 외경을 가압함과 동시에 체결캡(300)의 락킹부(340)가 캡체결부(140)에 걸려 조립이 이루어진다.1 to 6, the present invention includes a body 100 provided on a water purification line, a tube 200 inserted into the body to constitute a water purification line, and the tube is not separated in a state in which it is coupled to the body. It is configured to include a fastening cap 300 that is fastened and fixed to the body, and the body 100 is formed at the rear end of the tube inserting part 120 for inserting and fixing the tube, and the tube inserting part 120, and is fastened. The cap fastening part 140 to which the cap 300 is assembled is formed, and the fastening cap 200 is assembled by forcibly pressing the fastening cap 300 in a state where the tube 200 is inserted into the tube inserting part 120 . A pressing inclined surface 320 is formed on the inner diameter of the fastening cap 300 so that the pressing inclined surface 320 presses the outer diameter of the tube and at the same time the locking part 340 of the fastening cap 300 is the cap fastening part 140 assembly is carried out on

이때, 상기 튜브삽입부(120)는 튜브삽입관(122)과, 튜브삽입관(122)보다 더 큰 외경을 갖도록 되어 튜브의 내경에 압입되도록 튜브접속부(124)가 형성되며, 상기 튜브삽입관(122)에는 튜브(200)가 조립된 상태에서 튜브(200)의 회전을 방지하기 위한 튜브압착부(130)가 형성된다.At this time, the tube insertion portion 120 has a tube insertion tube 122 and a tube connection portion 124 so as to have a larger outer diameter than the tube insertion tube 122 to be press-fitted into the inner diameter of the tube, the tube insertion tube At 122, a tube compression unit 130 for preventing rotation of the tube 200 in an assembled state of the tube 200 is formed.

튜브압착부(130)는 튜브(200)가 튜브삽입관(122)에 삽입되고 체결캡(300)에 의하여 조립된 상태에서 외력이 작용하는 경우에도 튜브(200)의 회전을 방지하도록 하기 위한 것으로써 튜브(200)가 튜브삽입부(120)에 끼워 조립된 상태에서 회전방향에 대한 저항력을 증가시켜서 튜브(200)의 회전을 방지하게 된다.The tube compression unit 130 is to prevent the tube 200 from rotating even when an external force is applied in a state in which the tube 200 is inserted into the tube insertion tube 122 and assembled by the fastening cap 300 . In a state in which the tube 200 is inserted into the tube insertion part 120 and assembled, the resistance to the rotation direction is increased to prevent rotation of the tube 200 .

즉, 튜브압착부(130)는 튜브삽입관(122)의 외측 표면에 형성되며, 튜브(200)가 체결캡(300)에 의하여 압입 고정될 때 튜브삽입관(122)에 돌출 형성된 튜브압착부(130)와 체결캡(300)의 가압경사면(320)의 사이에 튜브(200)의 내,외면이 서로 맞물리게 지지되면서 튜브(200)가 더욱 긴밀히 결합될 수 있게 된다.That is, the tube compression unit 130 is formed on the outer surface of the tube insertion tube 122 , and when the tube 200 is press-fitted and fixed by the fastening cap 300 , the tube compression unit formed to protrude from the tube insertion tube 122 . As the inner and outer surfaces of the tube 200 are interlocked and supported between 130 and the pressure inclined surface 320 of the fastening cap 300, the tube 200 can be more closely coupled.

이때, 상기 튜브삽입관(122)은 튜브의 삽입 방향을 따라서 튜브삽입관(122)의 외경에 기울기를 갖는 배출유도면(123)이 형성될 수 있으며, 이 배출유도면(123)에 의하여 튜브(200)를 삽입할 때 튜브삽입관(122)과 튜브(200) 내경의 이격공간에 잔류하고 있는 공기가 배출되면서 튜브(200)와 튜브삽입관(122) 또는 튜브(200)와 튜브압착부(130)가 공기층에 의하여 체결불량이 발생하는 것을 방지할 수 있다.At this time, the tube insertion tube 122 may have a discharge guide surface 123 having an inclination to the outer diameter of the tube insertion tube 122 along the insertion direction of the tube, and the discharge guide surface 123 causes the tube When the 200 is inserted, the air remaining in the space between the tube insertion tube 122 and the tube 200 inner diameter is discharged while the tube 200 and the tube insertion tube 122 or the tube 200 and the tube compression unit are inserted. (130) It is possible to prevent the occurrence of a defective fastening due to the air layer.

즉, 튜브(200)를 튜브삽입부(120)에 끼울 경우에 튜브(200)의 선단은 튜브삽입관(122)과 캡체결부(140)의 경계에 형성되는 선단벽체(142)에 밀착될 때 까지 끼워진 상태에서 체결캡(300)을 이용하여 조립이 이루어지는데, 이때 체결캡(300)이 튜브(200)를 선단벽체(142)측으로 밀면서 조립이 이루어지게 되므로 튜브(200) 내측의 잔류공기가 쉽게 빠져나가지 못하는 문제가 있고, 튜브 내측에 잔류공기가 많을 경우에는 체결캡(300)의 내주연에 형성된 가압경사면(320)이 튜브(200)의 외경에 제대로 밀착되지 못하면서 튜브의 삽입, 인출방향에 대한 체결력은 확보되지만 튜브(200)의 길이방향 축을 기준으로 회전력에 대한 지지가 이루어지지 못하게 되므로 튜브(200)가 헛돌게 될 수 있는데, 상기와 같이 배출유도면(123)에 의하여 도 7에 도시된 바와 같이 공기배출을 유도함으로써 튜브내 잔류공기를 최소화하여 튜브가 튜브삽입부(120)의 표면에 밀착 단면적을 증가시켜 튜브(200)가 헛돌게 되는 것을 방지할 수 있다.That is, when the tube 200 is inserted into the tube insertion part 120, the tip of the tube 200 is in close contact with the tip wall 142 formed at the boundary between the tube insertion tube 122 and the cap fastening part 140. Assembly is made using the fastening cap 300 in a state of being fitted until There is a problem that the tube cannot easily escape, and when there is a lot of residual air inside the tube, the pressure inclined surface 320 formed on the inner periphery of the fastening cap 300 does not properly adhere to the outer diameter of the tube 200, and the insertion and withdrawal of the tube Although the fastening force for the direction is secured, the support for the rotational force is not made based on the longitudinal axis of the tube 200, so the tube 200 may be idle. As shown in, by inducing air discharge, residual air in the tube is minimized, thereby increasing the cross-sectional area of the tube in close contact with the surface of the tube insertion part 120, thereby preventing the tube 200 from spinning in vain.
