ことが免れなかつた。 The socket and plug are coupled and separated by engaging and releasing a lock ball provided on the socket side so as to move in a centripetal direction and a groove formed in the circumferential direction on the outer peripheral surface of the plug. Types of so-called quick fittings are known. However, in conventional pipe joints of this type, the number of parts that make up the socket is relatively large, seal rings are fitted at various locations to prevent fluid leakage, and the lock balls are attached to the socket body. Since the inner surface of the sleeve that surrounds the lock ball from the outer circumferential side restrains and releases the lock ball, the sleeve has a complicated cross-sectional shape, which increases the number of machining steps and increases costs. could not be avoided.

This is no different from the conventional one in that it has a fluid passage 12 that passes through the shaft center in the axial direction. Reference numeral 14 denotes the main part of the plug which is the connecting part with the socket 20, and the outer circumferential surface of this part has no steps as shown in FIG.
As is well known, an outer circumferential groove 16 that engages and disengages from the outer circumferential groove 16 is formed in the circumferential direction. Reference numeral 18 denotes a male screw provided at the terminal portion of the plug 10.

素材のニツプル３８を一連一体に有している。 A socket 20 that can be connected to and separated from the above plug 10
consists of a socket body 26 and a sleeve 36,
The axial center of the socket main body 26 has a fluid passage 24 that passes through it in the axial direction, and the end of the main body has a series of integral nipples 38 made of the same material.

向けて設ける。 A through hole 2 for supporting a lock ball 30 that engages and disengages from the outer circumferential groove 16 of the plug 10 is provided near the open end of the fluid passage 24 of the socket body 26.
8, as shown in FIG. 3, both open ends 32 and 34 have the smallest diameter, and the main parts are provided with the same diameter and oriented in the centrifugal direction.
ロツクボール３０の直径はソケツト本体２６の
肉厚より厚く、しかも、上記貫通孔２８の主要部

いる。 The diameter of the lock ball 30 is thicker than the wall thickness of the socket body 26, and is also the same diameter as the diameter of the main portion of the through hole 28. Therefore, as shown in FIG. It moves in a state of frictional contact with the circumferential wall of the portion, and when pressed most centripetally, a portion thereof protrudes into the fluid passage 24 of the socket body 26. Further, when the lock ball 30 is pressed in the most centrifugal direction, the ball moves while making frictional contact with the peripheral wall of the main part of the through hole 28, and a part of the ball comes to protrude to the outer peripheral surface of the socket body 26. There is.

するパツキングである。 The reason why both open ends 32 and 34 of the through hole 28 are made smaller than the diameter of the main part is to prevent the lock ball 30 from protruding unnecessarily. Therefore, the diameter can be easily reduced, and the other opening end can be easily reduced in diameter by, for example, drawing or caulking after drilling, and this diameter reduction process creates a stopper edge of the ball at both opening ends. form. 22 is plug 1
This is a packing that seals fluid when the socket 20 and the socket 20 are connected.

能に嵌合する。 The outer peripheral surface of the socket body 26 is connected to the through hole 28.
As mentioned above, the main part is formed on a flat surface with the same diameter, except for the stepped part at the end on the side where the sleeve is formed. They fit together so that they can slide in the direction.

るのを制止されるようになつている。 As is clear from FIG. 2, the sleeve 34 in FIG. when it stands out,
If this sleeve 36 is moved from the position shown in FIG. 1 to the position shown in FIG.
The lock ball 30 in the state shown in FIGS. 1 and 2 moves while receiving the frictional resistance of the through hole 28 of the socket body 26, and the portion facing the fluid passage 24 protrudes in the centrifugal direction. Unless a pressing force is applied from the centripetal direction, protrusion to the outer circumferential surface is prevented.
次に上記実施例に作用について説明する。 Next, the operation of the above embodiment will be explained.

い。 As shown in FIG.
When the lock ball 30 is moved to the 8 side, the lock ball 30 becomes able to move in the centrifugal direction within the through hole 28. However, in this case, the lock ball 30 does not move at all within the through hole 28, and a portion thereof remains protruding into the fluid passage 24 of the socket body 26. Therefore, the sleeve sleeve 36 is attached to the socket body 26.
However, if the hose is connected to the nipple 38 of the socket 20, the sleeve 36 will not fall off.

完了する。 Next, insert the plug 1 into the fluid passage 24 of the socket 20.
When the connecting portion 14 of No. 0 is inserted, the lock ball 30 is pressed in the centrifugal direction by the outer periphery of the tip end of the plug 10, and a portion of the lock ball 30 projects onto the outer periphery of the socket body 26. Next, as shown in FIG. 2, when the sleeve 36 is returned to the center of the socket body 26, the sleeve 36 presses the lock ball 30 in the centrifugal direction, so that the ball is pressed against the peripheral wall of the through hole 28 by a strong frictional force. Maintain a state of restrained movement. At this point, the connection between the socket 20 and the plug 10 is completed.

供給できる点で実用性は極めて大である。 Although the embodiments have been described above, the present invention provides a fluid passage that passes through the socket body in the axial direction at the axial center of the socket body whose outer circumferential surface of the main part is formed without any step. 1. Near the opening end, there is a groove formed in the circumferential direction on the outer circumferential surface of the plug and a through hole for supporting the lock ball that is engaged and removed. Both opening ends have the smallest diameter, and other main parts are generally the same. Provided in the diameter in a centrifugal direction, and
A lock ball having the same diameter as the main part of the hole is placed in the through hole, and when the ball is pressed the most in the centripetal direction, it moves in the centrifugal direction in a state of frictional contact so that a part of the ball protrudes with respect to the fluid passage. In addition, a sleeve that presses the lock ball toward the centripetal direction of the socket body is fitted to the main part of the outer peripheral surface of the socket body so as to be slidable in the axial direction. According to the socket, there is no need to provide a compression spring to press the sleeve as in the past, or to form a pressing part and a releasing part for the lock ball on the inner peripheral surface of the sleeve, and the overall structure is extremely simple. It becomes easier,
The number of parts is small and no machining is required, resulting in an inexpensive socket. Furthermore, since the socket of the present invention is extremely easy to connect and disconnect from a plug, as with the conventional socket, it is extremely practical in that it can be supplied at low cost.
