Is prevented from sliding out of the fitting body 10. The spring washer 23 is fixedly provided in the joint body 10, and a convex base 231 is provided on the spring washer 23. A convex portion 202 is provided on the front end surface of the sliding seat 20. One end of the return spring 22 is convex The other end is inserted on the raised portion 202, and the return spring 22 can be returned to the original position after the sliding seat 20 slides, that is, through the elastic force. The engagement end face 203 on the sliding seat 20 is brought into contact with the locking ring 24. A plurality of through portions 201 penetrating through the inner and outer end surfaces are uniformly disposed on the slide seat 20, have steps in the through portions 201, and have steps similarly on the locking teeth 21, and between the steps The outer surfaces of the locking teeth 21 have an inclined structure and are engaged in the through portion 201, and the teeth 211 on the locking teeth 21 enter the inner wall of the slide seat 20 and the outer peripheral surface of the pipe The structure in which such a tooth portion 211 is engaged with the outer peripheral surface of the pipe is more stable and has a longer life as compared with the conventional structure. The floating part 12 for moving the locking tooth 21 is opened on the inner wall of the joint body 10, and the floating part 12 is a downward slope, and when the sliding seat 20 is pushed inward, the penetrating part 201 is Since the locking tooth 21 is pressed to rotate downward and rotated into the slope, and thus the tooth portion 211 and the outer peripheral surface of the conduit can be separated, the pipe can be removed easily; Similarly, when the sliding seat 20 is pushed inward to rotate the locking tooth 21 into the floating part 12 at this time, the tooth part 211 is inserted into the penetrating part 201 and the pipe is inserted, and then sliding is performed. The seat 20 is loosened, and under the action of the return spring 22, the slide seat 20 moves outward, and at the same time, the penetrating portion 201 causes the locking tooth 21 to return to its original position and the tooth portion 211 to the outer circumferential surface of the pipe. After the sliding seat 20 has moved a fixed distance, The ability engaging end surface 203 is wearing engagement with the locking ring 24 on the serve fixed.

継手本体１０内に支持座金３０、第１シールリング３１及び第２シールリング３２を有し、支持座金３０は継手本体１０内に固設され、第１シールリング３１の一端が支持座金３０上に当接され、他端がばね座金２３の端面と当接し；第２シールリング３２の一端は、支持座金３０の端面に当接され、他端が継手本体１０の内底面と当接し、第１シールリング３１及び第２シールリング３２が使用時継手のシール性を増強できる。   The joint body 10 has a support washer 30, a first seal ring 31 and a second seal ring 32. The support washer 30 is fixed in the joint body 10, and one end of the first seal ring 31 is on the support washer 30. The other end abuts against the end face of the spring washer 23; one end of the second seal ring 32 abuts against the end face of the support washer 30, the other end abuts against the inner bottom surface of the joint body 10; The seal ring 31 and the second seal ring 32 can enhance the sealability of the joint in use.

本発明によると、パイプの係着が安定し、またパイプの着脱が容易であるので、産業上有用である。   The present invention is industrially useful because the attachment of the pipe is stable and the pipe can be easily attached and detached.
