特許第3549180号により提案されている。 In addition, as a hose joint for a vehicle air conditioner, a socket fitting formed by stepping a small-diameter cylindrical connecting wall with an inward flange at the tip is fitted onto the cylindrical part of the joint body, A gasket is interposed between two bent bead parts with an inward flange formed on the cylindrical part, and a gasket is sandwiched between the bead part located inside the socket fitting and the tip of the hose. After applying a mold release agent such as oil, silicone liquid, or grease to the inner surface of the connecting wall, a movable thermosetting annular resin layer such as neoprene or epoxy resin is applied. US Pat. No. 3,549,180 proposes a socket fitting that is caulked to the hose so that it is brought into pressure contact with the end surface of the hose by the fluid pressure leaking from between the socket and the hose.

けが不安定になり、高圧流体が洩れ易くなる。(Problems to be Solved by the Invention) By the way, in the former conventional fitting, the collar 2a of the socket fitting 2 is directly sandwiched between the two bead portions 1a and 1b of the fitting body 1, so
When the hose 3 is inserted between the joint body 1 and the socket fitting 2, the front end of the hose 3 hits the inner bead portion 1b, creating a gap above the bead portion 1b.
When the socket fitting 2 is caulked, the hose 3 escapes to the gap side, resulting in insufficient caulking.
Furthermore, the presence of voids causes the rubber hose to soften due to the influence of high-temperature fluid during use, making caulking unstable and making it easy for high-pressure fluid to leak.
そして、継手本体１とソケツト金具２は同じ材
料で硬度差がなく、ビード部１ａ，１ｂとこれに

を期待することができない。 The joint body 1 and the socket fitting 2 are made of the same material and have no difference in hardness, and there is no compressive deformation between the bead parts 1a, 1b and the collar 2a held between them. Almost no sealing effect can be expected.

ト高になつてしまう。 On the other hand, in the latter case, a gap is not created between the end of the hose and the inside of the socket fitting, and there is no risk of the hose escaping into the gap when the socket fitting is caulked. In addition to the gasket interposed between the two bead parts on the joint body, an annular resin layer made of thermosetting resin is required. Apply oil to those surfaces in advance to prevent them from adhering to the inner surface.
It is necessary to apply a mold release agent such as silicone, and after the resin layer is formed, it takes a certain amount of time for this to harden, which not only makes the construction complicated.
Assembly to the joint body is difficult and time consuming, resulting in high costs.
そこで、この考案はソケツト金具のかしめ加工
や高温高圧の流体の影響を受けてもホースが動く
ことなく、簡単な構成で結合状態が安定し、かつ
ソケツト金具結合部のシール効果が充分に得られ
るホース継手を提供するものである。 Therefore, this idea has a simple structure that does not cause the hose to move even when the socket fitting is caulked or is affected by high temperature and high pressure fluids, and the connection state is stable, and a sufficient sealing effect can be obtained at the socket fitting connection part. The present invention provides a hose joint.

で安価に生産できるなどの利点を有する。(Effects of the invention) As described above, in this invention, the hose is inserted between the fitting body made of pipe material and the socket fitting, and the hose is caulked together with the socket fitting against the fitting body. On the inside of the brim, there is an annular rib of a required width made of a material softer than the fitting body and the socket fitting, the outer diameter of which approximately matches the inner diameter of the socket fitting, and the inner circumference of which has an inner diameter approximately matching the outer diameter of the fitting body. A spacer ring is provided with an annular recess whose diameter and width approximately match the outer diameter and width of the bead portion located inside the socket fitting, and the annular rib is connected to the two-striped bead of the joint body 11 together with the collar of the socket fitting. At the same time, since the outer periphery of the bead part in the socket fitting is covered with the periphery of the spacer ring, the annular rib of the spacer ring provided in the socket fitting is compressed between the two bead parts. The airtightness of the joint between the socket fitting and the socket fitting can be maintained reliably through deformation alone, improving the packing effect, and since there is no gap between the socket fitting and the hose end unlike in the conventional case, the socket fitting can be easily sealed. The hose can be firmly caulked to the fitting body without movement during caulking, and the hose will not soften and flow even when exposed to high temperature fluid during use, maintaining a stable caulking condition. The internal fluid will not leak even after long-term use. Moreover,
As a sealing material for the socket fitting joint, no extra members other than the spacer ring are required, and the present invention has the advantage that it is not only simple in construction, but also easy to assemble to the joint body and can be manufactured at low cost.
