A variety of structures have been developed as pipe fittings for connecting flexible pipes for transferring fluids, but the common structure is that pipe fittings are arranged at equal intervals within the fitting body. The pipe enters the fitting body while pushing apart each locking claw of a locking body having a plurality of locking claws, for example, four locking claws, and the tip of each locking claw, which is a locking end, is pulled out of the pipe by a screw or other means. This device prevents the tube from being pulled out by tightening it so that it sinks into the wall, or by using elastic force or the like to automatically sink the tip of each lock claw into the outside wall of the tube. This is done by using artificial means or by using the elastic force of each locking claw itself to separate the tip of each locking claw from the outer wall surface of the tube. therefore,
In this type of pipe joint, the handling operation is complicated if special equipment is used to manually prevent and release the pipe from being pulled out, and the elastic force of the lock claw itself is In the case of the ones used, the marks where the tips of the locking claws have dug into the outer wall surface of the pipe over time form grooves, and these grooves engage the locking claws, making it difficult for them to spring back. The drawback was that it was difficult to pull out the tube. Considering the ease of handling, it is desirable to use the elastic force of the lock claw itself to prevent the tube from being pulled out and release it. It is necessary for the material to have both rigidity and elasticity, and meeting this condition is extremely difficult because it means satisfying contradictory properties in the same member. In order to solve this problem, the inventor of the present invention moved away from simultaneously requiring the above-mentioned conflicting properties in the lock pawl itself, and instead supported the rigid lock pawl with an elastic sleeve made of rubber, etc. A pipe joint equipped with a release ring was proposed (Japanese Patent Application Laid-Open No. 54-2652).
(Refer to No. 1), and as a further improvement to this, the elastic sleeve deflects in the axial direction of the joint body when inserting the pipe, and this deflection is released toward the inner wall surface of the joint body so that it does not hinder the smooth insertion of the pipe. To solve this problem, a pipe joint has been proposed in which a relief portion is provided at least on the end edge of the elastic sleeve where the lock claw contacts (Utility Model Application No. 55-7450). However,
As mentioned above, the lock pawls of the locking body in conventional pipe joints are generally provided in four pieces at equal intervals of 90 degrees in the circumferential direction, so the spacing between each lock pawl is wide. If the tube deforms into a square shape, it will easily come off from the joint body, and the pressing force applied to each lock pawl during front attachment and detachment will not necessarily be uniform, so each lock pawl will not deform uniformly. This has the disadvantage that the operation of attaching and detaching the tube may not be carried out smoothly.

The object of the present invention is to provide a locking body for a pipe joint that eliminates this drawback, and the feature is that the locking body is an annular flat plate body with a number of radial notches formed at least from its inner diameter edge. The locking end is formed by the inner diameter edge in which the plurality of radial notches are formed.

Reference numeral 13 denotes a locking body, which is made by punching out a flat plate-shaped elastic body such as a cylindrical plate into an annular shape, and has a large number of radial holes from each of the inner and outer edges. Cuts 14,15 are formed alternately. Each notch 15 is wider than each notch 14, in other words, the force between the notches at the inner diameter edge is greater than the notch interval at the outer diameter edge, and each of the notches 14 is formed. The inner diameter edge constitutes a locking end. Further, the locking body 13 is loosely fitted into the annular groove 8 at its outer diameter edge, and its inner diameter edge portion is loosely fitted into the annular groove 8.
It is in contact with the end of the relief groove 11 side. Note that the locking body 13
Since its elasticity is supplemented by the elastic sleeve 10, its material is not necessarily limited to an elastic body.

Reference numeral 16 designates a nearly cylindrical release ring, and its enlarged diameter step 17 abuts against the regulating step 7 of the support 5, while its flange 18 abuts the tube insertion end of the support 5. It is fitted and supported by the support body 5 so that its movement range in the axial direction is restricted. The outer peripheral surface of the release ring 16 is tapered so that the diameter decreases from the diameter-enlarging step 17 toward the tip, and at the tip, the inner diameter edge of the locking body 13 is directed toward the elastic sleeve 10. It's pushing. As a result, the locking body 13, which is originally flat, is deformed into a conical shape, and its inner diameter end is positioned so as to slightly protrude inward from the outer wall surface of the tube 9 into which it is inserted.

In the above configuration, when the tube 9 is inserted into the joint body 1 from the direction of the release ring 18, the tube 9 pushes the inner diameter edge of the locking body 13 against the elasticity of the elastic sleeve 10 that comes into contact with it. The tube 9 is deformed so as to move away from the outer wall surface, and is inserted to a predetermined position where the tip of the tube 9 comes into contact with the third step 4. At this time, the elastic sleeve 10 is pressed against the joint body 1 by the pressing force □ caused by the deformation of the locking body 13 due to the insertion of the pipe 9.
Deflection in the axial direction occurs, but the raku relief groove 11.12
Since the deflection is absorbed by the tube 9, the tube 9 is smoothly inserted to the predetermined position. When the tube 9 is inserted to a predetermined position, the inner diameter edge of the locking body 13 comes into elastic contact with the outer wall surface of the tube 9 by the elastic sleeve body 10 α, and when the tube 9 is pulled out, the elastic As the elastic sleeve 10 slightly bends in the direction in which the tube 9 is pulled out due to the friction generated between the body sleeve 10 and the outer wall surface of the tube 9, the inner diameter end edge of the locking body 13, which is the locking end, moves into the tube 9. Embedded in the outer wall surface of pipe 9
is held around almost its entire circumference to reliably prevent its movement.

If you want to remove the tube 9 from the joint body 1, insert the release ring 16' into the joint body 1' as shown below the straight line in FIG. Just move. Then, the tip of the release ring 16' pushes the inner edge of the locking body 13'' open toward the inner wall surface of the joint body 1' while resisting the elasticity of the elastic sleeve 10', and the outer edge of the pipe 9' is pushed open. Since the locking end embedded in the wall surface is separated from the tube 9'', the withdrawal prevention state is released and the tube 9' can be withdrawn very easily.

Thus, according to the present invention, the following effects can be achieved. First, since the inner diameter edge, which is the locking end, is divided into many parts by radial notches, the pressing force applied when attaching and detaching the tube is uniform, and its deformation is also uniform, so the operation of attaching and detaching the tube is extremely easy. It can be done smoothly and easily. Second, since the many portions of the inner diameter end edge that serve as the locking end are located in an annular shape and are embedded into the outer wall surface of the tube, they are held securely when the tube is inserted, and are prevented from deforming the tube. There will be no situation where you will be left out. Thirdly, since the IL body is flat, it is extremely easy to automate the process of forming the incisions, and mass production is possible. Fourthly, the locking body is flat and deformed into a conical shape by the release ring after being incorporated into the joint body, which is difficult to do when a conical body is assembled into the joint body. Automation is now possible, making installation work extremely efficient.
