に施したねじと、プラスチツク管の内面にねじ切りした
ねじ部とを嵌合することから、継手およびプラスチツク
管内面のねじ山が合わず嵌合し難いという問題がある。When joining a conventional plastic pipe with a joint, the threads on the joint and the threaded portion on the inner surface of the plastic pipe are fitted, so the threads of the joint and the inner surface of the plastic pipe do not match and it is difficult to fit. There is a problem.
また、接合が悪いと、プラスチツク管は相互に長さ方向
に対して斜めに嵌合する場合があり、確実な嵌合ができ
ないという問題がある。Further, if the joint is poor, the plastic tubes may be fitted to each other obliquely with respect to the lengthwise direction, and there is a problem that reliable fitting cannot be performed.

説明する。Since the plastic pipe joint of the present invention has a small-diameter guide portion at the tip of the threaded portion, insertion and fitting into the plastic pipe is easy and reliable, and a part of the outer circumference of the guide portion is screwed. By providing a convex section with the same screw as the section, if a concave section that fits the convex section provided on the joint is provided on the inner surface of the plastic pipe joint, the fitting will be easier and more secure. Therefore, the plastic tubes can be linearly and stably joined. Embodiments will be described below with reference to the drawings.

ら、とくにねじ切りは施してない。FIG. 1 shows the construction of an embodiment of a plastic pipe joint according to the present invention. 1 and 2 are plastic tubes that join each other,
Reference numeral 10 denotes a joint fitted to the plastic tube 1, and has a structure including a threaded portion 5 and a guide portion 7 that is not threaded at the tip portion, that is, has a smaller diameter than the outer diameter of the threaded portion. In this embodiment, the convex portion 3 having the same thread as the screw portion 5 is provided on a part of the outer circumference. On the inner surface of the other plastic pipe 2, which is joined to the plastic pipe 1, to which the joint 10 is fitted, the threaded portion 6 fitted to the threaded portion 5 of the joint 10 and the convex portion provided on the guide portion 7 are fitted. The concave portion 4 is provided, and since the concave portion 4 facilitates the insertion of the guide portion 7, it is not particularly threaded.

る。According to this embodiment, the fitting 10 is initially a plastic tube 1
The guide portion 7 having a smaller diameter than the inner diameters of 2 and 2 can be easily inserted into the plastic pipes 1 and 2 by fitting the convex portion 3 and the concave portion 4, and thereafter, the threaded portion 5 of the joint 10 and the plastic pipe 1 are joined. By engaging with the screw part 6 of 2 and 2,
The joint 10 can be fitted easily and surely without being fitted obliquely to the length direction of the plastic tubes 1 and 2.
なお継手全体のねじ山、ねじの長さは適宜でよく、凸状

ラスチツク管１および２相互が直線的に接合できる長さ
であればよく、継手全体のねじ長さの1/3程度でよい。The thread of the entire joint and the length of the screw may be appropriate, and the length of the convex portion 3 and the concave portion 4 on the inner surface of the plastic pipe may be any length as long as the plastic pipes 1 and 2 can be linearly joined to each other. Good, about 1/3 of the screw length of the entire joint is enough.
