Description of the Related Art When connecting a rubber hose or a synthetic resin hose to various devices, a connecting fitting having a threaded portion is fixed to one end of the hose, and the threaded portion of the connecting fitting is screwed to a mating member such as a manifold on the equipment side. The method of screwing to the part is common. However, in this method, when the connection fitting is rotated to screw the connection fitting fixed to one end of the hose into the mating member, the hose fixed to the connection fitting is necessarily rotated. Therefore, in this method, if one end of the hose whose other end is already fixed by joining is to be connected to the mating member,
There was a big drawback that the hose rotated when the fitting was screwed and the hose was twisted while being piped.

As described in JP-20290A, JP 61-166291A, etc., an annular convex portion is provided on the outer periphery of one end of the joint body, and the outer periphery of one end of the joint body is engaged with the convex portion. Some have a cap nut attached. But,
In this type of hose joint, a seal member such as an O-ring is arranged on the side surface of the convex portion on the side of the mating member, and the mating member screwed into the cap nut sandwiches and presses the seal member between the convex portion, It is designed to ensure sealing performance. Therefore, when the cap nut is screwed into the mating member, the joint body easily rotates together, and further, after the connection, the joint body and the hose fixed thereto cannot rotate with respect to the mating member. As described above, the conventional hose joint of this type is not a swivel joint, and is easily connected while the hose is twisted, and when the joint body has a curved portion, it is difficult to connect the direction as instructed.

It is fitted in the formed annular groove so as to be rotatable in the circumferential direction, and the other end of this joint body 3 is
After being inserted into the end, the outer periphery of the hose 1 and the joint body 3 is tightened and fixed by the socket 4. The adapter 5 is provided with male threads at both ends, and the male thread of one taper thread is screwed into the female thread (not shown) of the taper thread of the device side connection port, which is the mating member, so that the mating member can be sealed. Keep it fixed. The hose 1 is connected by rotating and screwing the sleeve nut 2 into the other male screw of the adapter 5 fixed to this mating member.

している。Since this conventional hose joint requires a dedicated adapter 5 in addition to the union nut or the sleeve nut 2, the number of parts is large, and the female screw of the union nut or the sleeve nut 2 and a screw for the female screw of the union nut or the sleeve nut 2 are required. Since the male screw of the adapter 5 to be fitted is not a taper screw which is usually used when a sealing property is required, but a special screw is used, the cost becomes very high. Further, since the sealability between the union nut or the sleeve nut 2 and the adapter 5 is not good, one end of the joint body 3 and the other end of the adapter 5 are tapered to be in pressure contact with each other to ensure the sealability.

ることが困難であった。However, this hose joint is not a so-called swivel joint, since the joint body 3 is pressed against the adapter 5 and the sleeve nut 2 to make it impossible to rotate after connecting to the mating member. Therefore, when the union nut or the sleeve nut 2 is screwed at the time of connecting the hose, the joint body 3 comes into contact with the adapter 5. Therefore, at the final point of screwing, the joint body 3 rotates together with the sleeve nut 2. As a result, the hose 1 is twisted. Therefore, the hose may be damaged if it is used as it is. Further, when the joint body has a curved portion, it is difficult to establish the directionality and connect the joint.

めて困難であった。On the other hand, the swivel joint is known as a rotatable joint, and is, for example, Japanese Utility Model Publication 61-1478.
Japanese Patent No. 6 discloses a swivel hose joint that allows the joint body to be rotatably connected to a mating member. In this swivel hose joint, the joint body should be equipped with a hose at one end and a socket with a threaded portion on the opposite side, and multiple balls should be arranged in the groove provided on the outer periphery of the joint body and the inner periphery of the socket. Thus, the joint body is rotatable with respect to the socket. Further, even if the socket is screwed to the mating member, the joint body does not come into contact with the mating member, so that the joint body can be rotatably connected to the mating member. However, since the conventional swivel hose joint is provided with a group of balls as described above, the structure is extremely complicated, and the structure becomes large in the axial direction and the radial direction. Moreover, it is not easy to assemble the joint, and the disassembly of the joint is not easy. It has been extremely difficult to replace a seal member such as an O-ring that has been damaged due to long-term use.

The joint body inserted into the through-hole of the threaded member is rotatable with respect to the threaded member, and the threaded member is provided movably in the axial direction at one end of the threaded body. The annular projection provided at one end abuts on the step between the large diameter portion of the screwing member and the through center hole, so that the screwing member cannot be detached to the outside of the one end side of the joint body. in addition,
Since the annular seal member mounted between the screwing member and the joint body is arranged in the circumferential groove provided in the annular convex portion of the joint body, it does not hinder the rotation of the screwing member.

きる。As a result, even when the mating member is screwed onto the mating member, the joint body is separated from the mating member and is rotatably held with respect to the mating member. Therefore, when the threaded member is screwed into the mating member to be connected, the hose fixed to the joint body is not twisted, and the joint body is rotatable with respect to the threaded member even after the connection. In addition, the annular seal member arranged on the annular convex portion can ensure sufficient sealing performance, and the annular convex portion also serves as the sealing portion, so that the length of the swivel hose joint can be reduced accordingly.

の移動を阻止することができる。By attaching the locking member to the outer periphery of one end of the joint body in contact with or close to the other end of the threaded member, the threaded member is directed toward the other end along the axis of the joint body. It is possible to keep the annular convex portion of the joint main body completely accommodated in the large diameter portion of the screwing member by restricting the movement of the joint main body. Therefore,
By attaching the locking member to the joint body, the movement of the screwing member is prevented so that the annular seal member in the circumferential groove on the outer periphery of the annular convex portion is not exposed not only when connected to the mating member but also during transportation. be able to.

トであることが必要である。Further, since the locking member can be removed from the outer peripheral portion of the joint body, if the annular seal member deteriorates due to long-term use, after removing the locking member, the screwing member is rotated to remove it from the mating member. The annular seal member is exposed by detaching it and moving it toward the hose side, so that the annular seal member can be easily replaced. The joint body may be straight tubular or may have a curved portion in the middle, but the threaded member engaged with the outer periphery of one end of the joint body is the other end (hose side).
At least one end of the fitting body must be substantially straight so that the annular seal member can be moved toward and exposed.

る。The large diameter portion 10a of the screwing member 9 is directed to one end side, and the straight portion 7 of the joint body 6 is inserted in the through center hole 10 thereof.
Is inserted so as to be rotatable in the circumferential direction and movable in the axial direction. The step between the small diameter portion 10b and the large diameter portion 10a of the through center hole 10 of the threaded member 9 abuts the annular convex portion 7a, and this step cannot move to the one end side of the joint body 6 beyond the annular convex portion 7a. The screwing member 9 cannot be removed from the one end side of the joint body 6. At the position where the screwing member 9 can no longer move to the one end side, the annular convex portion 7a of the joint body 6 is completely accommodated in the large diameter portion 10a of the screwing member 9.
