Abstract

The present invention relates to a hose connector capable of preventing separation and damages to an interior product by external force of a pressure of a fluid. In the hose connector, a plurality of external bodies are connected by a connection portion. An internal body is coupled to the inside of the external bodies, a fixing ring fixing the hose is inserted into the inside of the internal body, a plurality of coupling holes are radially formed on the outer circumferential surface of the external body, and a fixing ring formed to be corresponding to the outer circumferential surface of the internal body is fixed to the coupling hole. Therefore, if the hose is applied with strong artificial external force, or if the pressure within the hose suddenly increases, the fixing ring is able to strongly fix the hose, a stepped protrusion prevents separation of a front cover, and a holding ring fixed to the coupling hole prevents separation of the internal body such that a service life of the hose connector can be extended. In addition, a structure of the hose connector is simple such that manufacturing and assembly of the hose connector can be facilitated, and production costs can be reduced, thereby providing economic feasibility.

Description

호스 연결구{Hose connector}Hose connector {Hose connector}

본 발명은 각각의 호스를 서로 연결하여 유체를 이송하기 위한 연결구에 관한 것으로, 더욱 상세하게는 외력이나 유체의 압력에 의해 내측의 부품이 이탈하여 파손되는 것을 방지할 수 있는 호스 연결구에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connector for connecting fluids by connecting each hose to each other, and more particularly, to a hose connector capable of preventing internal components from being detached and damaged by external force or fluid pressure.

일반적으로 호스 연결구는 서로 분리된 호스를 일체로 연결하여 유체를 소통시키는 것으로, 그 종류로는 물 또는 기름 같은 액체를 소통시키는 것과, 공기 또는 가스와 같은 기체를 소통시키는 것으로 크게 나뉜다. Generally, a hose connector is a hose which connects separate hoses to each other to communicate fluid. The hose connector is widely divided into a liquid such as water or oil, and a gas such as air or gas.

이 중에 액체에 적용되는 호스 연결구는 대표적으로 정수기, 연수기 및 이온수기 등과 같은 가정용 수처리 장치에 내재된 플라스틱 호스를 연결하는 것, 산업 전반에 사용되는 기계류에 내재된 우레탄 재질의 호스를 연결하는 것으로 나뉜다.Among them, the hose connector to be applied to the liquid is divided into connecting the plastic hose embedded in the domestic water treatment apparatus such as water purifier, water softener and ionizer, and connecting the hose of the urethane material inherent in the machinery used throughout the industry.

도 1에서는 호스가 원터치로 결합되는 호스 연결구가 제안되어 있다.In Fig. 1, a hose connector is proposed in which a hose is connected at one-touch.

상기 원터치 호스 연결구는 호스가 삽입되는 지지구(3)와, 상기 지지구(3)를 삽입하여 고정시키는 본체(4)로 이루어지며, 상기 지지구(3)는 중앙에 위치한 구멍에 호스가 삽입될 경우, 그 호스가 탄력 지지되게 일정 간격으로 구비되는 다수개의 홀딩부(5)와, 그 홀딩부(5)의 선단부에 형성되는 걸림돌기(6)로 이루어진다.The one-touch hose connector comprises a support 3 for inserting a hose therein and a body 4 for fixing the support 3 by inserting the hose 3. The support 3 is provided with a hose A plurality of holding parts 5 provided at predetermined intervals so that the hose is elastically supported and a locking protrusion 6 formed at the tip of the holding part 5.

상기 본체(4)는 지지구(3)가 삽입되도록 내부에 중공이 형성되는 몸통부(7)와, 상기 지지구(3)의 걸림돌기(6)가 걸릴 수 있도록 상기 몸통부(7)의 내주면에 턱을 이루는 걸림부(8)와, 상기 걸림부(8)의 일측에 구비되는 오-링부재(10)로 이루어진다.The main body 4 includes a body 7 having a hollow formed therein for inserting the support 3 and a body 7 for holding the engagement protrusion 6 of the support 3. [ And an o-ring member (10) provided on one side of the engaging portion (8).

상기 호스가 끼워질 때 그 동작은, 먼저 지지구(3)의 구멍에 호스가 삽입되면, 지지구(3)의 홀딩부(5)가 외측으로 벌어진다. 그 후에, 홀딩부(5)의 걸림돌기(6)가 본체(4)의 걸림부(8)에 걸리게 되면서 홀딩부(5)가 호스의 외주면을 잡아 고정시킨다.When the hose is inserted, the operation thereof is such that, when the hose is first inserted into the hole of the support 3, the holding part 5 of the support 3 is opened to the outside. The holding portion 5 of the holding portion 5 is caught by the holding portion 8 of the main body 4 so that the holding portion 5 holds and fixes the outer peripheral surface of the hose.

만일, 호스가 파손되거나 노후하여 교체해야 할 경우, 이 호스를 분리시키기 위해서, 본체(4)의 일측에 노출된 지지구(3)의 끝단을 본체(4) 측으로 누르게 되면, 지지구(3)에서 홀딩부(5)의 걸림돌기(6)가 본체(4)의 걸림부(8)로부터 이격되고, 이 상태에서 호스를 일측으로 잡아당기면 호스가 분리된다.If the end of the support 3 exposed to one side of the main body 4 is pressed toward the main body 4 in order to separate the hose from the support 3 when the hose is damaged or old, The hooking protrusion 6 of the holding part 5 is separated from the latching part 8 of the main body 4. In this state, when the hose is pulled to one side, the hose is separated.

그러나 상술한 종래의 호스 연결구는 호스가 지지구(3)에 고정된 상태에서 인위적인 힘에 의해 호스가 억지로 끌어당겨 지거나, 호스 내의 압력이 고압으로 유지될 경우, 호스가 지지구(3)로부터 미끄러지면서 쉽게 이탈되거나, 또는 본체(4)에서 지지구(3) 및 걸림부(8)가 분리되는 문제점이 있었다.However, the above-described conventional hose connector can not prevent the hose from sliding from the support 3 when the hose is forcibly pulled by an artificial force while the hose is fixed to the support 3 or when the pressure in the hose is maintained at a high pressure. Or the support 3 and the fastening portion 8 are detached from the main body 4.

이에 따라 최근에는 결합부위에 별도의 락킹클립을 결합하여 결합력을 보강하고 있으나, 추가부품으로 인한 원가상승 및 작업시간의 증가로 인해 경제적이지 않은 문제점이 있었다.In recent years, a separate locking clip has been attached to the coupling portion to reinforce the coupling force. However, there has been a problem in that it is not economical due to cost increase due to additional parts and increase in working time.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 외측몸체와 내측몸체의 결합구조를 개선하여 수명을 연장한 호스 연결구를 제공하는 데 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a hose connector that improves the coupling structure between the outer body and the inner body to prolong the service life.

또한, 본 발명의 다른 목적은 단순한 구조의 결합에 의해 제조 및 조립이 용이하고 제품의 단가를 절감할 수 있는 호스 연결구를 제공하는 데 있다.Another object of the present invention is to provide a hose connector which is easy to manufacture and assemble by a simple structure and can reduce the cost of a product.

본 발명에 의한 호스 연결구는 복수의 외측몸체가 연결부에 의해 연결된 호스 연결구에 있어서, 상기 외측몸체의 내측에는 내측몸체가 결합되고, 상기 내측몸체의 내측에는 호스를 고정하는 고정링이 삽입되되, 상기 외측몸체의 외주면에는 복수의 결합홀이 방사상으로 형성되고, 상기 결합홀에는 내측몸체의 외주면에 대응하게 형성된 고정고리가 고정되는 것을 특징으로 한다.The hose connector according to the present invention is characterized in that the hose connector has a plurality of outer bodies connected to each other by a connecting portion, wherein an inner body is coupled to the inner side of the outer body and a retaining ring for inserting the hose is inserted into the inner side of the inner body, A plurality of coupling holes are radially formed on an outer circumferential surface of the outer body, and a fixing ring formed corresponding to an outer circumferential surface of the inner body is fixed to the coupling hole.

본 발명에 따른 호스 연결구에 의하면, 인위적인 힘에 의해 호스에 외측으로 강한 외력이 작용하거나, 호스 내의 압력이 갑자기 증가하더라도 고정링이 호스를 견고히 고정하고, 단턱은 전면커버의 이탈을 방지되며, 결합홀에 고정된 걸림고리는 내측몸체의 이탈을 방지하게 됨으로써 호스 연결구의 수명을 연장할 수 있다.According to the hose connector of the present invention, the hose can be firmly fixed by the fixing ring even when a strong external force acts on the hose due to an artificial force or suddenly increases the pressure in the hose, The retaining ring fixed to the hole prevents the detachment of the inner body, so that the life of the hose connector can be prolonged.

또한, 단순한 구성의 결합구조에 의해 제조 및 조립이 더욱 용이하고, 제품의 단가를 절감할 수 있어 더욱 경제적인 효과가 있다.Further, the manufacturing structure and the assembly can be made easier by the simple structure of the coupling structure, and the cost of the product can be reduced, which is more economical.
