- the tube 1 is held by the tube attachment/detachment member 100.
- the tube 1 and the body 2 are connected by the tube attachment/detachment member 100.
- FIG. 2 is an enlarged detailed view of part A shown in FIG. 1.
- the horizontal part 2B of the body 2 has an inner cylindrical part 2D and an outer cylindrical part 2E arranged to surround the inner cylindrical part 2D.
- the inner cylindrical part 2D extends from the outer cylindrical part 2E.
- the inner cylindrical part 2D and the outer cylindrical part 2E form the open end of the horizontal part 2B.
- the inner cylindrical part 2D is inserted into the tube 1.
- the tube attachment/detachment member 100 comprises a lock ring 10 that holds the tube 1, a release ring 20 that is arranged next to the lock ring 10, and a cap 30 that houses the lock ring 10 and the release ring 20.
- the lock ring 10 is made of, for example, metal.
- the release ring 20 and the cap 30 are made of, for example, resin.
- Figure 3 is a plan view of the lock ring 10. As shown in Figure 3, the lock ring 10 has a plurality of claws 11 arranged in an annular shape and a connecting portion 12 that connects adjacent claws 11 in the circumferential direction.
- circumferential direction refers to the direction around the central axis of the lock ring 10.
- radial direction refers to the direction emanating from the central axis of the lock ring 10.
- the connecting portion 12 is positioned radially outward from the claws 11.
- the lock ring 10 is a zigzag-shaped annular member in which the claws 11 are positioned relatively radially inward and the connecting portion 12 is positioned radially outward.
- the tube 1 is inserted into the lock ring 10.
- the insertion direction of the tube 1 is from right to left on the page in FIG. 2.
- the insertion direction of the tube 1 will also be simply referred to as the "insertion direction.”
- the claws 11 of the lock ring 10 are inclined with respect to the insertion direction so that they are inwardly directed radially toward the insertion direction.
- Figure 4 is an enlarged detailed view showing the state before the tube 1 is inserted into the lock ring 10, and corresponds to Figure 2.
- Figure 4 when the tube 1 is not inserted into the lock ring 10, the distance between the claws 11 facing each other in the radial direction is smaller than the outer diameter of the tube 1.
- the claws 11 of the lock ring 10 are pushed in the insertion direction by the tube 1, and are deformed so that the distance between the claws 11 facing each other in the radial direction increases (see Figure 2).
- FIG. 5 is an enlarged detailed view showing the state in which the hold of the tube 1 by the lock ring 10 has been released, and corresponds to Figure 2.
- the release ring 20 is aligned with the lock ring 10 in the insertion direction.
- the central axis of the release ring 20 and the central axis of the lock ring 10 are approximately aligned, and the tube 1 is inserted into the release ring 20.
- the release ring 20 extends from the cap 30 in the opposite direction to the insertion direction, allowing the user to operate the release ring 20.
- the release ring 20 moves in the insertion direction.
- movement in the insertion direction is also referred to as "forward”
- movement in the opposite direction to the insertion direction is also referred to as “reverse.”
- the release ring 20 is housed in the cap 30 so that it can move forward and backward relative to the lock ring 10.
- the release ring 20 When the release ring 20 is moved forward by the user's operation, the release ring 20 pushes the claws 11 of the lock ring 10 in the insertion direction as shown in FIG. 5. This causes the gap between the radially opposing claws 11 to widen, and the claws 11 move away from the tube 1. In this state, even if the tube 1 is pulled in the opposite direction to the insertion direction, the claws 11 of the lock ring 10 do not bite into the tube 1. Therefore, it becomes possible to remove the tube 1 from the lock ring 10.
- the release ring 20 releases the lock ring 10 from its hold on the tube 1 by deforming the lock ring 10 and separating it from the tube 1.
- the cap 30 has a reverse movement limiting portion 31 that limits the reverse movement of the release ring 20.
- the reverse movement limiting portion 31 is a step that protrudes radially inward.
- the release ring 20 has a step 21 that protrudes radially outward, and the reverse movement limiting portion 31 faces the step 21 in the insertion direction.
- the reverse movement limiting portion 31 and the step 21 are in contact with each other, the release ring 20 does not move backward. Therefore, it is possible to prevent the release ring 20 from falling out of the cap 30 in the direction opposite to the insertion direction.
- Figure 6 is a half-cut longitudinal section of the tube attachment/detachment member 100 before it is attached to the body 2.
- the tube attachment/detachment member 100 is equipped with a buckling ring 40 that limits the movement of the lock ring 10 and the release ring 20 in the insertion direction.
- the buckling ring 40 is made of, for example, resin.
- the lock ring 10 is attached inside the buckling ring 40.
- the buckling ring 40 is formed with a step that comes into contact with the connecting portion 12 of the lock ring 10, and the step limits the displacement of the connecting portion 12 of the lock ring 10 in the insertion direction.
- the buckling ring 40 has an inclined surface 41 that is inclined with respect to the insertion direction.
- the inclined surface 41 is inclined toward the insertion direction as it moves radially inward, similar to the claws 11 of the locking ring 10.
- the inclined surface 41 comes into contact with the claws 11 of the locking ring 10, limiting the deformation of the locking ring 10 by the release ring 20. This makes it possible to prevent excessive deformation of the locking ring 10. This makes it possible to prevent the locking ring 10 from being damaged and being unable to hold the tube 1.
- the buckling ring 40 is also sized to function as a backup ring for the sealing member 50, and has a stepped shape that fixes the sealing member 50.
- the buckling ring 40 is provided inside the cap 30.
- the central axis of the buckling ring 40 and the central axis of the locking ring 10 are approximately aligned, and when the tube 1 is inserted into the locking ring 10 (see FIG. 2), the tube 1 is inserted into the buckling ring 40.
- the buckling ring 40 is fitted into the cap 30.
- a protrusion 42 that protrudes radially outward is formed on the outer periphery of the buckling ring 40, and a first recessed portion 32 in which the protrusion 42 can be positioned is formed on the inner periphery of the cap 30.
- the protrusion 42 and the first recessed portion 32 are formed, for example, in an annular shape along the circumferential direction.
- the fitting of the buckling ring 40 into the cap 30 is not limited to the form of the protrusion 42 and the first recessed portion 32.
- a recessed portion may be formed on the outer periphery of the buckling ring 40
- a protrusion may be formed on the inner periphery of the cap 30, and the protrusion may be disposed in the recessed portion to hold the buckling ring 40 in the cap 30.
- a male thread may be formed on the outer periphery of the buckling ring 40, and a female thread may be formed on the inner periphery of the cap 30, and the buckling ring 40 may be held in the cap 30 by screwing the male thread and the female thread.
- the outer shape of the buckling ring 40 may be made larger than the inner shape of the cap 30, and the buckling ring 40 may be held in the cap 30 by pushing the cap 30 apart as the buckling ring 40 is inserted into the cap 30.
- the buckling ring 40 may also be made of metal, the protrusion 42 may be formed into an edge shape, and pressed into the cap 30 in which the first recessed portion 32 is not formed.
- a second recessed portion 33 separate from the first recessed portion 32 is formed on the inner circumference of the cap 30.
- the second recessed portion 33 is located on the insertion direction side of the buckling ring 40 (the left side of the paper in FIG. 6).
- the outer tubular portion 2E of the body 2 is inserted into the cap 30.
- the protrusion 2F formed on the outer periphery of the outer tubular portion 2E is positioned in the second recessed portion 33 of the cap 30, and the cap 30 is held in the body 2.
- the cap 30 is formed so that the outer periphery of the body 2 can be fitted into it.
- the fitting of the body 2 into the cap 30 is not limited to the form of the protrusion 2F and the second recess 33.
- a protrusion may be formed on the inner circumference of the cap 30 and a recess may be formed on the outer circumference of the body 2, and the protrusion may be disposed in the recess to hold the cap 30 to the body 2.
- a female thread may be formed on the inner circumference of the cap 30 and a male thread may be formed on the outer circumference of the body 2, and the cap 30 may be held to the body 2 by screwing the female thread into the male thread.
- the inner shape of the cap 30 may be made smaller than the outer shape of the body 2 when the body 2 is not inserted into the cap 30, and the cap 30 may be held to the body 2 by being pushed open by the body 2 as the body 2 is inserted into the cap 30.
- the buckling ring 40 provided in the cap 30 limits the movement of the lock ring 10 and release ring 20 housed in the cap 30, and the cap 30 is formed so that the outer periphery of the body 2 can be fitted into it.
- the same members can be used for the tube attachment/detachment member 100 as long as the corresponding tube outer diameter dimensions are the same for the body. Therefore, the tube attachment/detachment member 100 can be assembled and stored, and then assembled in a separate process according to the shape of the body 2 to complete the pipe fitting 1000. Furthermore, the assembly of the tube attachment/detachment member 100 can easily be automated by machine.
- a seal member 50 is provided between the outer periphery of the tube 1 and the inner periphery of the outer tubular portion 2E of the body 2.
- the seal member 50 is made of an elastic material such as rubber. The seal member 50 contacts the outer periphery of the tube 1 and the inner periphery of the outer tubular portion 2E of the body 2 to seal the gap between the tube 1 and the body 2 and ensure airtightness. This makes it possible to prevent fluid from leaking between the tube 1 and the body 2.
- the seal member 50 is housed in a step formed in the outer cylindrical portion 2E of the body 2.
- the buckling 40 is adjacent to the outer cylindrical portion 2E in the insertion direction, and prevents the seal member 50 from slipping out of the outer cylindrical portion 2E.
- the release ring 20 is attached to the cap 30 in the direction opposite to the insertion direction.
- the lock ring 10 is attached to the buckling ring 40.
- the buckling ring 40 is then press-fitted into the cap 30.
- the protrusion 42 of the buckling ring 40 is positioned in the first recess 32 of the cap 30, the buckling ring 40 is held in the cap 30, and assembly of the tube attachment/detachment member 100 is completed.
- the reverse movement limiting portion 31 of the cap 30 prevents the lock ring 10 and release ring 20 from falling out in the direction opposite to the insertion direction, and the buckling ring 40 prevents the lock ring 10 and release ring 20 from falling out in the insertion direction.
- the tube 1 is inserted into the tube attachment/detachment member 100 as shown in FIG. 2.
- the tube 1 is held by the lock ring 10.
- the release ring 20 may be pushed in the insertion direction to widen the gap between the claws 11 of the lock ring 10.
- the body 2 has an inner cylindrical portion 2D, but it does not have to have an inner cylindrical portion 2D.
- the buckling ring 40 limits the movement of the lock ring 10 and the release ring 20, and also limits the deformation of the lock ring 10 caused by the release ring 20.
- the buckling ring 40 may only limit the movement of the lock ring 10 and the release ring 20. In this case, it is preferable to provide a member separate from the buckling ring 40 that limits the deformation of the lock ring 10 caused by the release ring 20.
