As the pipe joint, for example, Patent Document 1 proposes a pipe joint having a jaw-shaped ring that engages a claw portion to an outer peripheral surface of the pipe to hold the pipe, and is adhered to the outer peripheral surface of the pipe to prevent it, and The cap of the joint body is covered, and the sleeve is expanded or contracted in the radial direction by opening and closing of a plurality of slits provided in the jacket to correspond to a plurality of tubes of a plurality of sizes. However, in the case of piping for supplying water or supplying hot water for a house, etc., if the wrong pipe is installed and the pipe is connected, the pipe must be taken out. However, in the case of the above-mentioned conventional pipe joint, in order to take out the pipe, it is necessary to disassemble the pipe joint from which the cap is removed and the jacket is taken out. As a result, when the installation of the pipe at the construction site is wrong, it takes time to disassemble and assemble the pipe joint, and the work efficiency is lowered. Also, in the case of prioritizing work efficiency, it is also possible to discard the incorrectly installed pipe and pipe joint. Thus, a conventional technique, such as Patent Document 2, which can take out a tube without disassembling the pipe joint, proposes a pipe joint having a joint body, a 0-ring, a jacket, and a branch ring, which is taken from the joint body. 3 201040428 When the time comes out, push the ^ into the direction of the pipe insertion, so that the taper part of the taper part is set with respect to the taper of the branch ring = straight == the gripper claw part is from the outer peripheral surface of the pipe ^ Patent .

The jacket 40 is cylindrically arranged to be closer to the insertion opening side than the second flange of the support ring 5〇, and its axial direction and the joint are selected. One end of the jacket 4 in the axial direction, 4〇El, is inserted closer to the support ring 5 than the first flange portion 52 of the second phase. The second flange portion 52 and the second portion have a plurality of slits 44 extending in a predetermined interval in the circumferential direction. The axial side of the body 10 of the body 40 is swam, and the opening and closing of the slot 44 allows the example of the figure to be collapsed or contracted. In addition, the form of the slit is not limited, and the number or shape thereof may be appropriately selected, and is not limited to the means for the slit holder 4 to expand or contract, or by synthesis Elastic 7 or the like, such as rubber (elastomer), forms a jacket 40. The jacket 40 has a plurality of claw portions 42 projecting inward in the radial direction of the jacket 40 at the inner surface of the portion between the slits 44. The claw portion 42 is engaged with the outer peripheral surface of the inserted tube to hold the tube. The claw portion 42 is oriented toward a structure in which the inner diameter of the jacket 40 is contracted in the Y direction and obliquely and is covered with a resin at the leaf spring (example shown in the drawing), and may be a resin only without using a leaf spring. Composition. The μ η jacket 40 has a first tapered portion 46 之外 at the outer surface near the one end 40E of the jacket 40 and the claw portion 42. The i-th tapered 46T direction is such that the outer diameter of the jacket 40 is expanded in the γ direction, and is slidable with respect to the tapered portion 22 provided in the cap 20 to be described later. The sleeve 40 is on the side of the 〇-shaped ring 30. The mountain has a second tapered cap. The inner surface of W〇E2 has #4〇〇P and the tapered portion 48 is oriented such that the inner diameter of 忐= is expanded in the Y direction = the tapered portion 56T provided by the support ring 50 is performed. (4) The cap 20 is cylindrical, and is used as a plug-in for inserting the tube, and is oriented toward the opening on the side of the opening of the end view 1 and is thinner from the axial direction. 2 %% is screwed to form: the internal thread 26 is formed. The external thread 16 at one end 1 〇 & side outer surface 8 201040428 of the inner body 10 is such that the cap 2 is mounted to the outer surface of the joint body 1 and its axial direction is formed with the joint body 1 Consistent. Here, the manner in which the second flange portion 52 of the support ring 50 is gripped by the cap 20 and one end 10 of the joint body 10, thereby fixing the support ring 5 is important. Further, the cap 20 is provided with a tapered portion 22T at the inner surface between the insertion opening and the internal thread 26. The tapered portion 22T is inclined in a direction in which the inner diameter of the cap 20 is expanded in the γ direction, and is slidable relative to the tapered portion 46T provided in the jacket 40. The function of the pipe joint of the present invention when the pipe is inserted will be described with reference to Figs. 3 to 5 . Figure 3 shows a section of the pipe joint of the present invention after the tube is unloaded. In the case of no load, there is no flow of water in the pipe p, that is, the pipe p and the pipe joint 1 are not subjected to water pressure. (4) 'The official? When inserted in the gamma direction, the claw portion 42 of the jacket 4G, such as the P' sleeve 40, moves in the γ direction in the same direction as the tube p. The second tapered portion 48T of the ring 50 ^ 40 sets will be opposite to the support: so that the jacket: d:: moves, and by the width expansion of the slot 44, the z is reduced, and the sleeve 40 is held by the tube The power of p makes it possible to reduce the eve and the tube p can be easily inserted. The fixed structure is subject to the jacket 40 by the joint body 10 and the cap 20: when the P# is inserted, the support ring 50 is not! b Pushing & is necessary to move above, so that the gap between the teether and the step portion 12 can be ensured by the gap between the pockets 30 and the step 10 2010. The I! I, that is, if the support ring 50 is not fixed, the tube p is When the π-type two-milk moves in the Y direction, the ring 5 is also moved in the direction of the support ring 5, so that the ring 5 is supported and deformed. The surviving surname, ^30 The inner limb edge makes the ◦-shaped ring 3G face the radial direction. The reed II therefore has the problem of making it difficult to insert the tube P. In the present invention, the gauntlet P. , ^ ^ is not deformed by pushing and squeezing, so that the problem of the Cypriot can be prevented. =4系_The pipe joint of the present invention is inserted into the pipe of the present invention, and water or air flows through the ρ π Μ heart mandrel, that is, s ΐ: the master 1 is subjected to water pressure or air pressure. Out; 2: When the joint 1 is subjected to water pressure, the pipe ρ will move toward the pull-out (4). In the first stage, tf ρ is oriented toward Υ, and when the direction is called the test movement, the taper of the support ring 50 in the spring 4 滑动 slides relative to the narrow and #^, by the width of the slot 44, the force is increased; 〇The other ^Twisted contraction' so the jacket 40 holds the ρ 5 ' of the tube ρ.

When it is removed, as shown by the arrow in Fig. 5(a), the special straightening or screw driver for moving the sleeve 4G is inserted from the gap between the cap box 20 and the other end of the box. When pressed in the direction and the γ direction, the jacket 4G moves toward the 丫 direction, and the other end 2 of the 4 4Q abuts to the fulcrum ring %. For more details, set it in the clamp, 4. The other end-to-end implant 2 (four) 2 miscellaneous portion 48 is abutted to the tapered portion 56 of the second flange portion 54 of the support 50. Then, as shown in Fig. 5(b), when the jacket 4 is further pushed in the γ direction, the second tapered portion 48 is slid in the γ direction with respect to the tapered portion 56. At this time, the width of the slit 44 of the jacket 40 is widened to expand the diameter of the jacket 40 to release the engagement between the claw portion 42 and the outer peripheral surface of the tube ρ. That is, when the jacket 4 is forcibly moved in the γ direction, the diameter of the jacket 40 is expanded enough to release the clamping action of the claws 42 on the tube ρ. As a result, the tube can be pulled out. Further, it is presumed that the use of a one-word driver or the like to push the jacket 40 in the γ direction is preferable because one end of the jacket 40 is formed in a vertical plane with respect to the Υ direction. Moreover, when the entire circumference of one end of the jacket 40 is 40 Ε!, that is, when one end 々 OEi of the jacket 40 is not 11 201040428 δ is further provided with a slot 44, and is only disposed at the other end 4 〇 In the case of e2, the position where the word driver is inserted is not limited, so it is preferable. Further, in the case where one end 々OEi of the jacket 40 is located at the outer side of the insertion opening, the above-described removal operation of the tube p can be easily performed. = 疋, in consideration of the case where the pipe P is pulled out by mistake, as shown in the example, it is preferable that one end 40& of the ferrule 40 is located closer to the insertion side than the one end of the cap 2 〇 】 ε.
