본 발명은 합성수지로 만들어지는 관 연결부재에 관한 것이다.The present invention relates to a pipe connecting member made of synthetic resin.

종래 합성수지를 재료로 하여 만든 관 연결부재는 널리 알려져 있는데 이러한 관 연결부재는 제조가 용이하고 무게가 가벼우며 또 내약품성이 있는 등의 장점이 있는 반면에 강도면에 약해 조여지는 부분에 이완이 생겨 유체가 새는 등의 난점이 있었다. 때문에 합성수지부재에 금속재의 보강부재를 집어넣은 것이 고려되고 있지만 이경우에는 금속부분이 노출되므로 부식, 녹등의 문제가 있게 된다. 따라서 본 발명의 목적은 제조가 용이하여 경량이고 또 내약품성등이 있는 합성수지 재질인 것을 특징으로 하면서 강도가 크고 변형되지 않으며 조입부분에 있어서도 이완이 생기지 않고 또한 유체이 누수염려가 없는 합성수지재질의 관 연결부재를 제공함과 동시에 이러한 관 연결부재를 용이하게 제조하는 방법을 제공하는 것이다.Conventionally, pipe connecting members made of synthetic resins are widely known. Such pipe connecting members are easy to manufacture, light in weight, and have chemical resistance, but have weakness in strength and loosening in tightened parts. There were difficulties such as leaking fluid. Therefore, it is considered that the reinforcing member of the metal material is put into the synthetic resin member, but in this case, since the metal part is exposed, there is a problem such as corrosion and rust. Therefore, the object of the present invention is characterized by a synthetic resin material that is easy to manufacture, lightweight and has chemical resistance, and has a high strength, does not deform, and does not cause loosening in the inserting part and does not cause leakage of fluid, and the connection of the synthetic resin material To provide a member and at the same time to provide a method for easily manufacturing such a pipe connecting member.

이를 위해 본 발명의 관 연결부재는 합성수지재질로 된 내부 원통체의 외측에 강도가 높은 재료로 구성되는 보강부재를 장착하며, 그리고 그 바깥쪽에 합성수지 성형으로 이루어지는 본체부를 내부 원통체와 일체로 형성해 전술한 내부 원통체와 본체부로 보강부재가 노출되지 않도록 피복하고 있다.To this end, the pipe connecting member of the present invention is equipped with a reinforcing member made of a material of high strength on the outer side of the inner cylindrical body made of a synthetic resin material, and formed on the outer side of the body portion made of synthetic resin molding integrally with the inner cylindrical body and described above. The inner cylindrical body and the main body portion are coated so that the reinforcing member is not exposed.

그리고 전술한 보강부재는 금속재질 또는 경도가 높은 합성수지재질 또는 경도가 높은 세라믹재질의 것이다. 전술한 관 연결부재의 제조방법은, 원통형상의 내부 원통체를 합성수지로 만들고 전술한 내부 원통체의 외측에 강도가 높은 재료로 구성되는 보강부재를 결합시키고 전술한 보강부재가 결합된 내부 원통체를 금형내에 세트시켜 합성수지의 사출성형으로 내부 원통체와 일체적으로 결합된 본체부를 만들어 이루어지는 것이다.The above reinforcing member is made of metal or high hardness synthetic resin or high hardness ceramic. The above-described method of manufacturing a pipe connecting member is made of a cylindrical inner cylindrical body made of synthetic resin, and combines a reinforcing member made of a material of high strength on the outer side of the inner cylindrical body and combines the inner cylindrical body with the aforementioned reinforcing member. It is made in the mold to make the body part integrally combined with the inner cylindrical body by injection molding of synthetic resin.

전술한 구성으로 이루어진 관 연결부재는 전 노출부분 및 구성부재의 대부분이 합성수지재질이므로 내약품성이 있고 경량이며 또한 강도가 높은 보강부재가 내장되어 있으므로 변형의 우려가 없으며 강도가 높다. 그리고 전술한 합성수지 성형으로써 제조하면 제조공정이 간단해 용이하게 제조할 수 있다.The pipe connection member having the above-described configuration is chemically resistant, lightweight, and has a high strength reinforcing member because most of the exposed parts and components are made of synthetic resin, so there is no fear of deformation and high strength. And if it is manufactured by the above-mentioned synthetic resin molding, the manufacturing process is simple and can be easily produced.

The main body part 3 which consists of these is formed integrally with the internal cylindrical body 1, and is covered so that the reinforcement member 2 may not be exposed by the internal cylindrical body 1 and the main body part 3 mentioned above. The inner cylindrical body 1 described above is made by injection molding or cutting, for example, using a synthetic resin such as polyamide, polyacetal, PBT, polyethylene, or fluororesin as a material. The reinforcing member 2 may be made of metal or high strength synthetic resin material or high strength ceramic material. In the case of using a synthetic resin material, it is necessary to use a synthetic resin material having a high strength even though the chemical resistance is weak, for example, different from the material of the inner cylindrical body 1 or the main body part 3. The reinforcing member 2 is circular in cross section and is fitted to the outside of the inner cylindrical body 1, but as shown in the figure, the reinforcing member 2 can be carried out by using one round cylindrical shape, and also by using a plurality of narrow shapes. It may be.

다음에 전술한 구조로 된 관 연결부재의 제조방법을 설명한다.Next, a manufacturing method of the pipe connecting member having the above-described structure will be described.

우선 제3도에서와 같은 내부 원통체(1)를 원통형상으로 해서 합성수지로 만들며 전술한 내부 원통체(1)의 바깥쪽에 강도가 높은 재료로 이루어진 제2도와 같은 보강부재(2)를 결합시켜 제4도와 같이 내무 원통체(1)와 보강부재(2)를 조합한 것을 만든다. 이와 같이 해서, 보강부재(2)가 결합된 내부 원통체(1)를 금형내에 세트시켜 합성수지의 사출성형으로 제1도와 같은 내부 원통체(1)와 일체적으로 결합된 본체부(3)를 만든다. 본체부(3)의 재료는 내부 원통체(1)와 동일한 합성수지 재료 또는 내부 원통체(1)의 재료와 친화성이 높은 합성수지 장치료를 사용해 본체부(3)를 성형할 때 내부원통체(1)와 본체부(3)의 접합북 융착상태를 얻도록, 즉, 내부 원통체(1)의 본체부(3)가 일체적으로 형성되도록 한다.First, the inner cylindrical body 1 as shown in FIG. 3 is made into a cylindrical shape and made of synthetic resin, and the reinforcing member 2 as shown in FIG. 2 made of a material of high strength is joined to the outer side of the inner cylindrical body 1 described above. As shown in Fig. 4, the inner cylindrical body 1 and the reinforcing member 2 are combined. In this way, the inner cylindrical body 1 to which the reinforcing member 2 is coupled is set in the mold, and the main body part 3 integrally coupled with the inner cylindrical body 1 as shown in FIG. 1 by injection molding of synthetic resin is provided. Make. The material of the main body 3 may be formed of an internal cylindrical body when the main body 3 is formed by using the same synthetic resin material as the inner cylindrical body 1 or a synthetic resin material having high affinity with the material of the inner cylindrical body 1. In order to obtain a bonded book fusion state between 1) and the main body 3, that is, the main body 3 of the inner cylindrical body 1 is integrally formed.

그리고 제5도에 나타낸 실시예는 내부 원통체(1)의 한쪽 단부에 함몰부(4)를 만들어 이 함몰부(4)에 본체부(3)의 합성수지재료가 파고들어 내부 원통체(1)와 본체부(3)의 결합이 보다 강력해지도록 한 것이다. 본 발명은 전술과 같은 구성을 가지므로 이러한 관 연결부재는 합성수지의 경량성, 내약품성, 제조용이성등의 특장점을 가지며 보강부재(2)에 의해 큰 강도를 유지할 수 있어 외부로부터의 죄임등의 힘이 가해지는 경우에도 변형이 없고, 또한 부식이나 녹이 날 우려가 없으며, 관의 접속부로부터 유체가 누설되어 흐를 우려도 없고, 또한 합성수지 성형으로 제조할 수 있으므로 제조를 용이하고 염가로 할 수 있다.In the embodiment shown in FIG. 5, a recess 4 is formed at one end of the inner cylindrical body 1 so that the synthetic resin material of the main body 3 penetrates into the recess 4 so that the inner cylindrical body 1 is closed. The main body portion 3 and the combination is to be stronger. Since the present invention has the configuration as described above, such a pipe connecting member has features such as light weight, chemical resistance, and ease of manufacture of synthetic resin, and can maintain a large strength by the reinforcing member (2), such as force from the outside Even if this is applied, there is no deformation, there is no fear of corrosion or rust, there is no fear of fluid leakage from the connection part of the pipe, and since it can be produced by synthetic resin molding, the production can be made easily and inexpensively.
