【発明の詳細な説明】
本発明は、プラスチックパイプを接続するパツキン２有
するメカニカル型プラスチック製の継手に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanical type plastic joint having a packing 2 for connecting plastic pipes.
従来品に於いては、ステイフナ−が継手本体と別体であ
り、部品件数が多いので施工性が悪く、ステイフナ−の
挿入忘れなどの欠点を有していた。In conventional products, the stiffener is separate from the joint body, and the number of parts is large, resulting in poor workability and drawbacks such as forgetting to insert the stiffener.
本発明は、本体とステイフナ−を一体化する事により、
前記の問題を解消する施工性のすぐれた配管ミスのない
プラスチック類の継手を提供するものである。By integrating the main body and the stiffener, the present invention
The object of the present invention is to provide a plastic joint that solves the above problems and has excellent workability and is free from piping mistakes.
本発明は、前記パイプの内部に挿入されるステイフナ−
’＆本体の内部と一体化して成型された事を特徴とする
。The present invention provides a stiffener inserted into the inside of the pipe.
'& It is characterized by being molded integrally with the inside of the main body.
以下に実施例を示す。Examples are shown below.
第１図は、本体と同じ材料もしくは金属の管状ステイフ

る。Washer 6. It is composed of a retaining ring 7 and a nut 2, and by tightening the nut 2, the retaining ring 7, which has a tapered outer periphery, is tightened and is made of a plastic material that prevents the pipe 4 from being pulled out. This is a mechanical joint, and for construction, simply inserting the pipe into the main joint and tightening the nut 2 is sufficient to reinforce the inserted portion of the pipe 4 and to provide a connection with sufficient resistance to pull out.
第２図は、前記パイプ４の引き抜は阻止力を前記第１図
のものよりさらに増す為に本体内部の管状ステイフナ−
３の外周な波山に成型したものである。FIG. 2 shows that the pipe 4 is pulled out using a tubular stiffener inside the main body in order to increase the stopping force even more than that of FIG. 1.
It is molded into a wave peak around the outer circumference of 3.

り内部流体が通り抜けても、パツキン５によってシール
されている為、漏れは完全に防止される。According to the present invention, when connecting the pipe 4, there is no need to insert a stiffener into the pipe 4 in advance as in the conventional case, and therefore, piping mistakes due to forgetting to insert a stiffener are completely eliminated, and the connection of the pipe 4 is completely eliminated. By tightening the nut 2, the inner surface and the outer surface of the stainer 3 are brought into close contact with each other, thereby preventing leakage of internal fluid. Furthermore, even if the internal fluid passes through the gap, it is sealed by the packing 5, so leakage is completely prevented.
又、第２図に示すステイフナ−３の波山を持つ外面形状
に於いては、配管後の引抜は応力に対し、高い抵抗力が
あり引抜は防止力を得る。In addition, the outer surface shape of the stiffener 3 shown in FIG. 2 having undulating crests has a high resistance against stress when the piping is pulled out after piping, thereby providing a force that prevents pulling out.
