Definitions
- the present invention relates to a pipe joint, and more particularly to a female joint of a pipe joint suitable for handling a high-pressure fluid.
- a pipe joint is configured such that both joints are connected and fixed in a state where the male joint is inserted into the female joint.
- a ball that is displaceable in the radial direction is provided in the male joint receiving portion, and the ball is displaced radially inward with the male joint inserted into the male joint receiving portion. It is designed to engage with a ball receiving recess provided on the outer peripheral surface (see Japanese Patent Application 2003-133618).
- a so-called collet chuck type fixing means may be used. That is, the fixing means is provided at a certain interval around the male joint receiving portion of the female joint, and each of the fixing means extends in the male joint receiving direction of the male joint receiving portion. Has a locking claw, supports the locking claw so that it can swing like a lever, and engages a locking part provided at the tip of the locking claw with a locking recess provided in the outer peripheral surface of the male joint.
- the locking portion of the locking claw is less prone to indentation than the above-described ball.
- the locking claw is provided at the distal end portion of the male joint receiving portion of the female joint, and the male joint is received in the locking claw with the locking portion extended outward in the radial direction. Since the locking part is displaced inward in the radial direction with respect to the mold joint, the male joint and the female joint are not necessarily accurately centered in the state where the locking is performed. The result is that the male and female joints are not properly connected. There is a risk of losing things.
