接続構造に係るものである。[Means for Solving the Problems] The present invention provides a method for attaching a bag from the resin pipe side to a threaded portion provided on the outer peripheral surface of the joint body while the end of the resin pipe is fitted into the end of the joint body. The present invention relates to a connection structure for connecting and fixing the resin pipe and the joint body by screwing together a nut.

When the cap nut is screwed onto the joint main body, the ring-shaped seal member receives pressing forces in opposite directions from the inner wall surface of the cap nut and the end surface of the joint main body. Due to the pressure, the interval between the recesses is narrowed and the inner circumferential surface thereof is bent to bulge inward, and the inner circumferential surface of the resin pipe is formed on the outer circumferential surface of the fitting member due to the deflection of the sealing member. Their shapes and mutual positional relationships are selected so that they fit into the grooves.

Then, a cap nut is screwed into the threaded portion provided on the outer peripheral surface of the joint body from the resin pipe side. Then, the ring-shaped seal member receives strong pressing forces in opposite directions from the inner wall surface of the cap nut and the end surface of the joint body. Due to this pressing force, the intervals between the recesses provided on the outer peripheral surface of the ring-shaped seal member are narrowed, and the inner peripheral surface of the ring-shaped seal member bulges inward. Due to this swelling of the inner circumferential surface, the ring-shaped seal member strongly presses the outer circumferential surface of the resin pipe. As a result, the joint body and the resin pipe are connected in a strongly sealed state, and the liquid in the conduit of the resin pipe will not leak to the outside.

This prevents the resin pipe from slipping and prevents it from coming off the joint body.

し固定するための接続構造を提供するものである。In this invention, with the end of the resin pipe 5 fitted into the end of the joint body 1, the cap nut 2 is screwed into the threaded portion 1a provided on the outer peripheral surface of the joint body 1 from the resin pipe 5 side. By matching them together, a connection structure for connecting and fixing the resin pipe 5 and the joint body 1 is provided.

第１図を参照して、樹脂管５の端部が継手本体１の端部
に嵌め入れられている。樹脂管５の端部には、該樹脂管
５に嵌まり込み該樹脂管５の内周面に接触する嵌込み部
材４が嵌め込まれている。Referring to FIG. 1, the end of the resin pipe 5 is fitted into the end of the joint body 1. A fitting member 4 that fits into the resin tube 5 and comes into contact with the inner circumferential surface of the resin tube 5 is fitted into the end of the resin tube 5 .
嵌込み部材４はたとえば硬質金属で形成される。The fitting member 4 is made of, for example, hard metal.

ていても相当の効果を実現し得る。Furthermore, a cut groove 4a is formed in a portion of the outer circumferential surface of the fitting member 4 that contacts the inner circumferential surface of the resin tube 5. In a preferred embodiment, one surface of the cut groove 4a is cut vertically, and the other surface is cut into an inclined surface. By selecting a cut groove having such a shape, it is possible to efficiently prevent the resin pipe 5 from coming off as described later. However, the present invention is not limited to this shape, and considerable effects can be achieved even if both sides are cut into slopes.

にしても相当の効果が得られる。A ring-shaped sealing member 3 is disposed on the outer peripheral surface of the resin pipe 5 and between the end surface 1b of the joint body 1 and the inner wall surface 2a of the cap nut 2. A recess 3a extending in the circumferential direction is formed on the outer peripheral surface of the ring-shaped seal member 3. Furthermore, the ring-shaped seal member 3 is provided with an inclined surface that matches the shape of the inner wall surface 2a of the cap nut 2 and the end surface 1b of the joint body 1. Strong contact between the end surface 1b of the joint body 1 and the inclined surface 3b of the sealing member 3 prevents the liquid in the pipe from leaking to the outside. Further, the reason why the ring-shaped seal member 3 is provided with such an inclined surface is that when the ring-shaped seal member 3 receives opposing pressing forces from the inner wall surface 2a of the cap nut 2 and the end surface 1b of the joint body 1,
This is to make the ring-shaped seal member 3 more flexible. Note that although both sides are sloped, a considerable effect can be obtained even if only one side is sloped.
また、リング状シール部材３の外周面に円周方向に沿っ
て延びる凹部３ａを設けたのも同じ理由による。Further, the reason why the recess 3a extending in the circumferential direction is provided on the outer peripheral surface of the ring-shaped seal member 3 is also based on the same reason.
次に、第１図および第２図を参照して、樹脂管５と継手
本体１の接続の動作について説明する。Next, the operation of connecting the resin pipe 5 and the joint body 1 will be described with reference to FIGS. 1 and 2.

体１と樹脂管５とは強くシールされた状態で接続され、
樹脂管５の管路内の液体は外部に漏れなくなる。Then, a ring-shaped sealing member 3 is disposed on the outer circumferential surface of the end portion of the resin pipe 5, in which a recess 3a extending in the circumferential direction is formed on the outer circumferential surface. With the resin pipe 5 in this state, its end is fitted into the end of the joint body 1. Then, a threaded portion 1 provided on the outer peripheral surface of the joint body 1
Screw the cap nut 2 onto the resin tube 5 side from the resin pipe 5 side. Then, the ring-shaped seal member 3 receives pressing forces from the inner wall surface 2a of the cap nut 2 and the end surface 1b of the joint body 1 in opposite directions. Due to this pressing force, the ring-shaped seal member 3
The interval between the recesses 3a is sandwiched, and the ring-shaped seal member 3
is bent so that its inner peripheral surface bulges inward, and strongly presses the outer peripheral surface of the resin tube 5 (FIG. 2). As a result, the joint body 1 and the resin pipe 5 are connected in a strongly sealed state,
The liquid within the conduit of the resin pipe 5 will no longer leak to the outside.
また、上記リング状シール部材３の撓みによって、上記

ジ４ｂ側の面を斜面にし、他方の面を垂直に切り込んだ
ような形状に選ぶことにより、樹脂管５の抜けが強力に
止められる。Further, due to the bending of the ring-shaped seal member 3, the inner circumferential surface of the resin tube 5 bites into the cut groove 4a formed on the outer circumferential surface of the fitting member 4. This prevents the resin pipe 5 from slipping, and prevents the resin pipe 5 from coming off from the joint body 1. In this case, by selecting the shape of the groove 4a such that the surface on the flange 4b side is sloped and the other surface is cut vertically as shown in the figure, the resin pipe 5 can be strongly prevented from coming off.

For example, as shown in FIG. 3, the present invention can be applied to the case where resin pipes 5 are connected to each other by the joint body 1.
