In this way, the pressing member 200, the rotating operating portion 300, and the locking member 400 are integrated and rotated through the joining of the rotating connection parts installed in the respective members 200, 300, 400; however, the locking member 400 is Install in the axial direction with play. In FIG. 2, the gap S1 between the bottom surface of the concave portion 222 and the lower end surface of the lower extension portion 412 is shown. This gap S1 ensures the clearance; the clearance is adjusted by adjusting the pressing force held by the rotating operation portion 300 The axial distance between the member 200 and the upper wall 106 can be set. Due to this play, the locking member 400 can move in the axial direction "slightly" for the pressing member 200; the locking member 400 can move in the axial direction "slightly" for the upper wall 106 "lower surface 122". The locking member 400 can be moved to a first position where the second engagement portion E2 is engaged with the first engagement portion E1 and a second position where the engagement of the second engagement portion E2 and the aforementioned first engagement portion E1 is released; this position changes, The integral rotation of the pressing member 200, the rotating operation part 300, and the locking member 400 is not impaired. Regardless of the axial position of the locking member 400, the pressing member 200, the rotating operation portion 300, and the locking member 400 rotate integrally.

As mentioned above, the body member 100 is provided with a first joint part E1 "refer to FIG. 5(c)"; and the locking member 400 is provided with a second joint part E2 "refer to FIG. 8(a)". 1 The joint part E1 protrudes from the second joint part E2 side "lower side"; the first joint part E1 and the second joint part E2 can be joined; once the first joint part E1 and the second joint part E2 are joined, the body member 100 , The locking member 400 cannot rotate; the engagement of the first engaging portion E1 and the second engaging portion E2 hinders the rotation of the locking member 400; that is, this engagement hinders the pressing member 200, the rotating operation portion 300, and the locking member 400 By the braking member 500, the second engaging portion E2 has been pressed on the first engaging portion E1; by the braking member 500, the second engaging portion E2 has been engaged with the first engaging portion E1.

Fig. 9 is a perspective view showing the water pipe connector 10 in a fixed state and a released state; Fig. 10 is a side view of the water pipe connector 10 in a fixed state and a released state seen from the side of the faucet; Fig. 11 shows a fixed state and a released state A cross-sectional view of the water pipe connector 10; the fixed state of FIG. 11 is a cross-sectional view along the line AA of FIG. 10, and the released state of FIG. 11 is a cross-sectional view along the line BB of FIG. 10.

As shown in FIG. 9, when moving from the fixed state to the released state, the rotating operating part 300 rotates in the direction R1, which is called the relaxation direction; when changing from the released state to the fixed state, the rotating operating part 300 rotates along the direction R1. Rotation in the direction R2, this direction R2 is called the locking direction.

[Fixed state] In a state where the outlet pipe f3 is inserted into the outlet pipe insertion portion 530, since the outlet pipe f3 is pressed by the pressing member 200, the water pipe connector 10 is fixed to the faucet f1 "refer to FIG. 2". As mentioned above, the axial position of the pressing contact surface M1 of the pressing member 200 changes with the circumferential position of the pressing contact surface M1. Therefore, due to the rotation of the pressing member 200, the distance between the outlet pipe f3 and the pressing contact surface M1 changes. 2 and 3, the outlet pipe f3 extends from the faucet body f2 toward the outlet f6 to the lower side. Therefore, near the receiving opening 108, the outlet pipe f3 is relatively located on the upper side. As the pressing member 200 rotates in the locking direction R2, at the circumferential position on the receiving opening 108 side, the axial position of the pressing contact surface M1 is lowered "refer to FIGS. 9 to 11"; by rotating the pressing member 200, the contact surface M1 is pressed Touch the outlet pipe f3.

In the rotation of the locking direction R2, the rotating operating part 300 rotates until the pressing contact surface M1 contacts the water outlet pipe f3; further, until the water pipe connector 10 is fixed, the rotating operating part 300 rotates in the locking direction R2. As mentioned above, by the braking member 500, the second engagement portion E2 is always engaged with the first engagement portion E1, and the rotation operation portion 300 can be rotated by operating the rotation operation portion 300 with a force that overcomes the engagement force. Due to the aforementioned play, the locking member 400 can be moved to the position "second position" where the engagement of the second engagement portion E2 and the first engagement portion E1 is released. Due to the increased operating force, the lock is opposed to the braking force of the brake member 500. The holding member 400 is lowered and the rotating operating part rotates. In order not to make the operating force too large, the braking force "Spring constant" of the braking member 500 should be set; in order not to make this operating force too large, the length of the lever portion 304 should be set .

When water is discharged from the faucet f1, the faucet f1 receives a force in the direction of the water due to the water pressure. Due to this force, the pressing force pressing the contact surface M1 increases; this pressing force includes a component in the axial direction, and if the pressing force increases, The second joint part E2 is strongly pressed against the first joint part E1; the counter force of this pressing force contains an upward component in the axial direction, and the locking member 400 is pressed upward by the water pressure, and the first The contact pressure between the joint part E1 and the second joint part E2 increases. As a result, the joint force of the joint parts E1 and E2 increases, and it becomes difficult for the rotation operation part 300 to rotate in the loosening direction R1. The water pipe connector 10 is difficult to fall off due to water pressure; the water pipe connector 10 has excellent water pressure resistance.

Furthermore, the brake member 500 may not be present. When the water pressure is applied, even if the brake member 500 is not present, the contact pressure of the first engagement portion E1 and the second engagement portion E2 increases. Therefore, even without the brake member 500, the water pressure resistance performance can be achieved.

In this embodiment, a braking member 500 is designed. As mentioned above, the locking member 400 has a play in the axial direction. With this play, it is possible to move "down" from the first position where the second joint part E2 is joined to the first joint part E1 to the first joint part E1 and the second joint part E1. The second position where the engagement of the engagement portion E2 is released; thus, against the engagement of the first engagement portion E1 and the second engagement portion E2, the rotary operation portion 300 can be rotated. On the other hand, this backlash can be a cause of relaxation. In particular, when the water pressure is not acting, the contact pressures of the joint parts E1 and E2 become weak, and the rotating operation part 300 is likely to rotate in the relaxation direction R1. Due to the strong locking of the rotating operating part 300, although the contact pressure of the joint parts E1 and E2 is increased, if the posture or position of the water pipe connector 10 is even slightly changed, the positional relationship between the pressing contact surface M1 and the outlet pipe f3 will change. , The aforementioned contact pressure may decrease. Since the brake member 500 brakes the second engagement portion E2 on the first engagement portion E1 side, even in a state where there is no water pressure, the engagement force of the engagement portions E1 and E2 can be maintained, and the occurrence of loosening can be suppressed.

[Release state] In order to release the fixed state, the rotating operation part 300 is rotated in the loosening direction R1. With this rotation, the phase of the pressing member 200 changes. At the circumferential position on the side of the receiving opening 108, the pressing contact surface M1 rises "refer to Figures 9 to 11"; as a result, the pressing contact surface M1 leaves the outlet pipe f3 .

In the fixed state, the pressing contact surface M1 presses the outlet pipe f3, and the joining force of the joining parts E1 and E2 is very high; that is, this joining force is related to the hydrostatic pressure and hydrodynamic pressure. 》It does not matter whether it is present or not, it is very high that the engagement will not be released for unintentionally applied forces or various vibrations. However, especially when the water pressure is not acting, the engagement force can be overcome and the rotating operation part 300 can be rotated in the loosening direction R1. By applying an operating force above a certain level, the braking force of the brake member 500 is overcome, and the engagement of the engaging parts E1 and E2 is released, and the rotating operating part 300 can be rotated in the loosening direction R1. Compared with the state where the water pressure is acting, when the water pressure is not working, the contact pressure of the joint parts E1 and E2 is smaller; compared with the state where the water pressure is working, when the water pressure is not working , Rotating in the loose direction R1 requires less operating force to complete. In a state where water pressure is acting, it is difficult to disengage the engagement portions E1 and E2. Therefore, in a flowing water state where water pressure is acting, it is possible to prevent the disengagement from being disengaged due to an operating error.

In the state where the outlet pipe f3 is inserted, the water pipe connector 10 can hardly rotate with respect to the outlet pipe f3. However, due to the slight gap between the receiving opening 108 and the outlet pipe f3, the water pipe connector 10 can slightly affect the outlet pipe f3. Spin. When the rotating operation part 300 is rotated in the loosening direction R1 from the fixed state, not only the rotating operation part 300 but also the entire water pipe connector 10 can be slightly rotated with respect to the faucet f1. The entire action of the water pipe connector 10 is caused by the slight change in the positional relationship between the outlet pipe f3 and the pressing contact surface M1. The pressing force applied by the pressing contact surface M1 to the outlet pipe f3 can be reduced. To lock the rotating operating part 300, when the rotating operating part 300 is to be rotated in the loosening direction R1, the contact pressure of the engaging parts E1 and E2 can also be reduced. Moreover, even when the rotating operation part 300 is not easy to rotate, if the operation force is repeatedly applied to the rotating operation part 300, the posture or position of the water pipe connector 10 will change, and the positional relationship between the outlet pipe f3 and the pressing contact surface M1 can be changed Slowly; furthermore, each member of the water pipe connector 10 deflection "elastic deformation". Therefore, even if the rotating operation part 300 is strongly locked in the fixed state, it is relatively easy The rotation operation part 300 is rotated in the loosening direction R1.

As mentioned above, the aforementioned clearance in the locking member 400 contributes to the reduction of the operating force required to rotate in the loosening direction R1. However, this clearance may be absent. For example, by joining the first joint The convex part of the part E1 and/or the second joint part E2 is made of a material that is easy to elastically deform, and there is no displacement of the locking member 400, and it can still be rotated in the loose direction R1 that opposes the joint force of the joint parts E1 and E2 . Also, as will be described later, even when the engagement of the engagement parts E1 and E2 is friction engagement, there is no displacement of the lock member 400, and the engagement force of the engagement parts E1 and E2 can still be loosened. Rotate slowly in the direction R1. When there is no such clearance, the brake member 500 may not be required.

Fig. 12(a) is a perspective view of the pressing member 250 viewed from above; Fig. 12(b) is a plan view of the pressing member 250; Fig. 12(c) is a side view of the pressing member 250 Figure 12 (d) is a perspective view of the pressing member 250 seen from below; Figure 12 (e) is a bottom view of the pressing member 250 (bottom view).

The pressing member 250 has a rotation connection part 252 and a side wall part 254. The side wall part 254 is formed around the rotating connection part 250; the side wall part 254 has a circumferential outer surface 258 and a circumferential inner surface 260. The pressing member 250 has a notch portion 262 that is partially missing in the circumferential direction.

The side wall portion 254 has a radial distance changing portion 264 that gradually changes the distance from the rotation axis Z2 of the pressing member 250 with the circumferential position; the radial distance changing portion 264 is formed at the lower part of the side wall portion 254.

The pressing member 250 has a pressing contact surface M2. In this embodiment, the pressing contact surface M2 is the lower end surface 266 of the pressing member 250; the pressing contact surface M2 is the lower end surface 266 of the radial distance changing portion 264. The pressing contact surface M2 extends around the rotation axis Z2; the pressing contact surface M2 has a portion inclined with respect to the rotation axis Z2; and the pressing contact surface M2 has a portion perpendicular to the rotation axis Z2. As shown in FIG. 12(c), the pressing contact surface M2 forms a stepped shape; the pressing contact surface M2 has a portion that moves in the circumferential direction and drives the axis direction to change. The axial position of the pressing contact surface M2 "lower end surface 266" changes slowly or stepwise with its circumferential position; the axial position of the pressing contact surface M2 changes with its phase.

The rotating connection portion 252 has a connection hole 270, a concave portion 272 and a convex portion 274. The connecting hole 270 is a connecting hole with a non-circular cross-section; the cross-sectional shape of the concave portion 272 is a non-circular shape. In the concave portion 272, the outer surface of the hole forming wall portion 276 in which the connecting hole 270 is formed is used as the first side surface, and the inner circumferential surface 260 is used as the second side surface; The shape of the surface. The convex part 274 is installed in two locations in the circumferential direction; the convex part 274 extends between the hole forming wall part 276 and the circumferential inner surface 260.

The difference between this pressing member 250 "Figure 12 (a) ~ (e)" and the aforementioned pressing member 200 "Figure 6 (a) ~ (e)" is the shape of the pressing contact surface. In the pressing contact surface M1 of the first embodiment and the pressing contact surface M2 of the second embodiment, the axial position changes with the circumferential position; in the pressing contact surface M1 and the pressing contact surface M2, by The rotation of the pressing member centered on the rotation axis Z2 changes the distance from the outlet pipe f3 "curved portion f5".

As shown in FIG. 6(d), the pressing contact surface M1 has a first end t1 and a second end t2. Among the first end t1 to the second end t2, the axial position of the second end t2 is lower than the axial position of the first end t1; the axial position of the pressing contact surface M1, as it approaches the second end t2 It gradually decreases; in all circumferential positions, the pressing contact surface M1 is inclined with respect to the axial direction. As shown in FIG. 12(d), the pressing contact surface M2 has a first end t1 and a second end t2. From the first end t1 to the second end t2, the axial position of the pressing contact surface M2 gradually decreases as it approaches the second end t2; the portion of the pressing contact surface M2 perpendicular to the axial direction and inclined with respect to the axial direction part. On the pressing contact surface M1, as the circumferential position approaches the second end t2, the axial position decreases; on the pressing contact surface M2, as the circumferential position approaches the second end t2, there is a portion where the axial position decreases and the axial direction Constantly located part. In the pressing contact surface M1 and the pressing contact surface M2, as the position in the circumferential direction approaches the second end t2, there is no part where the position in the axial direction rises.

The pressing contact surface M1 and the pressing contact surface M2 are inclined and/or stepped surfaces formed along the spiral. The so-called inclined plane is a surface inclined with respect to the axis of rotation Z2; the angle of the axis of rotation Z2 with respect to the inclined plane can be constant or variable; the inclined plane can be flat or curved. The so-called stepped surface is a surface in which a surface perpendicular to the axis of rotation Z2 and a surface that is not perpendicular to the axis of rotation Z2 are alternately arranged; the surface that is not perpendicular to the axis of rotation Z2 includes a plane that contains the axis of rotation Z2 and is parallel. A plane on the rotation axis Z2 and a surface inclined with respect to the rotation axis Z2. In this way, the pressing contact surface M1 and the pressing contact surface M2 can press the outlet pipe f3 in the fixed state, and in the released state, it does not prevent the outlet pipe f3 from being inserted into the water pipe connector 10.

Since the first joint part E1 and the second joint part E2 are joined, the relative movement between the first joint part E1 and the second joint part E2 is hindered. As a result, the locking member 400 is blocked with respect to the main body member 100. It cannot be rotated, that is, relative to the body member 100, the pressing member 200 cannot be rotated. The fixed state is maintained by the joining of the joining parts E1 and E2.

In the foregoing embodiment, the engagement of the first engagement portion E1 and the second engagement portion E2 is a shape engagement by shape engagement; the term "shape engagement" is as defined in this application . Typical examples of the shape joint are the joint between the convex parts and the joint between the convex part and the concave part. This shape engagement includes an engagement engagement in which one or more protrusions as the first engagement portion E1 and a plurality of protrusions as the second engagement portion E2 engage.

The joining of the first joining part E1 and the second joining part E2 is not limited to the aforementioned shape joining. For example, the joining of the first joining part E1 and the second joining part E2 may be friction joining by friction; In this case, the first joining portion E1 and the second joining portion E2 may be flat surfaces, for example. Since the pressing force of the second joint part E2 on the first joint part E1 by the water pressure is increased, the normal force of the contact surface of the joint parts E1 and E2 increases, and the friction force "static friction force" friction force) "Increase. Even if the first joining part E1 and the second joining part E2 are joined by the friction force "static friction force", the same effect as the aforementioned embodiment can be achieved.

In this embodiment, the first joining portion E1 is installed on the main body member 100; the first joining portion E1 may also be provided on a member different from the main body member 100. The first joining portion E1 is fixed to the main body member 100 or joined to the main body member 100. In the foregoing embodiment, the first joining portion E1 is installed on the body member 100 itself. The member having the first joining portion E1 is a different member from the main body member 100, and the different member may also be fixed to the main body member 100. The member having the first joining portion E1 is a different member from the body member 100, and this different member can also be joined to the body member 100. In this case, the joining may be a form joint or a friction joint; for example, , This different member can be a rubber member with no unevenness on the upper surface and lower surface, and is configured in an independently rotatable state. The upper surface "flat surface" of this rubber member can also be frictionally engaged with the body member 100; Furthermore, the lower surface "flat surface" of this rubber member, as the first joining portion E1, may be frictionally joined to the flat second joining portion E2.

In the foregoing embodiment, the rotating operation portion 300 has a lever portion 304; the lever portion 304 may not be provided. For example, the rotating operation part 300 may also be a dial. With the lever portion 304, the distance from the rotation axis Z3 increases, and the moment of the operating force becomes larger; and the lever portion 304 protruding outward in the radial direction becomes easy to apply force to the rotating operating portion 300, which As a result, the operating force can be reduced. As mentioned above, when rotating the rotary operating part 300 from the fixed state to the loosening direction R1, a relatively large operating force is required. The lever portion 304 can suppress the operating force when the fixed state is released.

In FIG. 7(e), the two arrows indicate the distance from the rotation axis Z3 to the front end of the lever portion 304 as indicated by D3, and this distance is measured along the direction perpendicular to the rotation axis Z3. From the viewpoint of suppressing the operating force and improving operability, the distance D3 is preferably 18 millimeters (mm) or more, more preferably 19 millimeters or more, and even more preferably 20 millimeters or more. From the viewpoint of miniaturization of the water pipe connector 10, the distance D3 is preferably 23 mm or less, more preferably 22 mm or less, and more preferably 21 mm or less.

In the aforementioned new patent application publication No. 49-7477, the water pipe joint is installed on the faucet by tightening the screw "bolt", if the lead angle of the fixing screw is large. , It is easy to loosen due to water pressure or vibration when pulling the water pipe. Therefore, in the New Patent Application Publication No. Sho 49-7477, the lead angle of the fixing screw is small. If the lead angle is small, the number of screw rotations required to lock the fixing screw will increase, resulting in poor operability. . In this embodiment, the rotation stop caused by the joining parts E1 and E2 is difficult to loosen. Therefore, the lead angle of the pressing contact surface can be increased.

From the viewpoint of fixing with a small rotation angle and improving operability, the lead angle θ of the pressing contact surface "refer to Figure 6(c)", 10° or more is ideal, and 11° or more is more ideal. 12° or more is more ideal; 45° or less is ideal, 40° or less is more ideal, and 35° or less is more ideal. In the pressing contact surface M1 of the first embodiment, the lead angle θ is 13.5°. The lead angle θ is the angle formed by the plane perpendicular to the rotation axis Z2 and the pressing contact surface, and the lead angle θ may be constant or variable.

Furthermore, the lead angle θ in the present application can also be an average lead angle. With the concept of an average lead angle, for example, even the pressing contact surface M2 shown in FIG. 12(a)~(e) , It is also possible to determine the lead angle θ. The length of the longitudinal direction of the pressing contact surface is taken as L1, and the axial distance between the first end t1 and the second end t2 is taken as D1. When referring to Figure 6(c), the average lead angle is used Solve the following formula, you can calculate it. tanθa = D1/L1 Furthermore, the length L1 is the length "distance length" when the center line formed by the set of the center points in the width direction of the pressing contact surface is seen in a plane line of sight. The so-called plane line of sight means the bottom view of FIG. 6(e) ( bottom view).

In this embodiment, because the lead angle θ can be made larger, the rotation angle of the rotating operation part 300 can be made smaller. In addition, since the rotation angle of the rotary operation part 300 is made less than 360°, the situation that the rotary operation part 300 "lever part 304" hits the faucet f1 "handle f4" can prevent the operation from obstructing the operation "refer to Figure 1. ". In addition, since the rotation angle of the rotating operation part 300 is made less than 360°, a notch part 212 can be provided in the pressing member 200 "refer to FIGS. 6(a)~(e)", so that the outlet pipe f3 can be inserted into the water pipe connector 10 easily. From these points of view, the rotatable angle of the rotating operation part 300 is ideal for 300° or less, 280° or less is more ideal, and 260° or less is more ideal; to avoid excessive lead angle θ From a point of view, the rotatable angle of the rotating operation part 300 is ideally 180° or more, 200° or more is more ideal, and 220° or more is more ideal. At the water pipe connector 10, the rotatable angle of the rotating operation part 300 is made 240°.

The two arrows θ1 in FIG. 6(e) indicate the circumferential angle of the pressing contact surface, and this angle θ1 is the circumferential angle from the first end t1 to the second end t2. Considering the function of pressing the contact surface, it is not necessary to make this angle θ1 larger than the rotatable angle of the rotating operation part 300; this angle θ1 is smaller than the rotatable angle of the rotating operation part 300, which is more ideal. The rotatable angle and lead angle θ of the rotating operating part 300 fit within the ideal range, from the viewpoint of versatility for different faucets and the installation of the opening part "notch part 212" in the pressing member 200 to facilitate the insertion of the outlet pipe f3 It can be seen that the angle θ1, 255° or less is ideal, 235° or less is more ideal, and 215° or less is more ideal. From the viewpoint of avoiding an excessively large lead angle θ, the angle θ1, 135° or more is ideal, 155° or more is more ideal, and 175° or more is more ideal. In the water pipe connector 10, the angle θ1 is set to 195°.

The aforementioned Japanese Patent Laid-Open No. 2017-219194 discloses an embodiment with an adjustment part and a backrotation preventing member. In this embodiment, although it is difficult to prevent the adjustment part from rotating backward and loosening, To release the fixation, the upper member must be removed from the lower member. In this case, the main body must be divided into an upper member and a lower member; compared with the case of an integrated system, on the body where the upper member and the lower member are joined, the source Since this engagement, movement between the components occurs. Due to the movement between the components, the contact portion of the contact faucet may move away from the faucet, and this movement reduces the fixity of the water pipe connector.

In the foregoing embodiment, the rotating operation part 300 can be rotated from the fixed state to the loose direction R1. Therefore, the entire body member can be integrally formed. As a result, in the fixed state, the pressing contact surface M1 is not easy to move, and it is not easy to move. Produce slack.

In the aforementioned Japanese Patent Laid-Open No. 2017-219194, in order to combine plural components for use, especially at the time of initial use, the usage method is intuitively difficult to understand; also, due to the division into plural components, there may be missing components. Risk; In addition, when using other components such as ring joints, there is a risk of damage due to stepping on the dropped parts. In the foregoing embodiment, since there are no separate components during use, such problems will not occur.

The number of convex portions 140 constituting the first joining portion E1 is not limited; the number of convex portions 140 may be one or plural. From the viewpoint of preventing the rotation of the pressing member 200 from stopping, and further, from the viewpoint of preparation when a part of the convex portion 140 is damaged or worn, the number of the convex portions 140 is preferably 2 or more, and more preferably 3 or more. By suppressing the number of convex portions 140, the minimum force required for operation becomes smaller, and the operability is improved. In addition, by suppressing the number of convex portions 140, mold forming becomes easy. From these viewpoints, the number of convex portions 140 is preferably 10 or less, more preferably 8 or less, and more preferably 6 or less.

The water pipe connector 10 corresponds to the wall-mounted faucet, the wall-mounted faucet "flexible type" and the wall-mounted faucet "spout rotation type". As mentioned above, these three types of faucets are specified in the Japanese Industrial Standards (JIS; Japanese Industrial Standards) B 2061. In addition, other faucets "laboratory faucet, etc." with similar outlet pipe f3 and curved part f5 of these faucets can also be used; and, by adjusting the size, it can also correspond to standing faucet, etc. .

As shown in FIG. 11, the outlet pipe insertion portion 530 "inner surface" has an upper side forming portion 532 adjacent to the upper side of the gasket 510, and when the gasket 510 is deformed by the outlet pipe f3, a space for accommodating the deformed portion is formed The space forming portion 534, the lower side forming portion 536 adjacent to the lower side of the space forming portion 534, and the inner concave portion 538 adjacent to the lower side of the lower side forming portion 536. The lower side forming portion 536 is a protrusion; since the space forming portion 534 and the inner concave portion 538 have formed a recessed portion, the lower side forming portion 536 between them has a protrusion structure. A downward surface 540 is formed at the boundary between the lower side forming portion 536 and the inner concave portion 538, and the downward surface 540 is the lower surface of the lower side forming portion 536. At the lower side of the inner concave portion 538, a rib 542 protruding toward the inner side of the outlet pipe insertion portion 530 is formed, and the rib 542 extends in the axial direction.

As shown in Figures 2 and 3, in the case of the wall-mounted faucet, in the fixed state, the front end of the outlet pipe f3 contacts the lower side forming part 536; and, with the posture of the water pipe connector 10, the outlet pipe f3 of the wall-mounted faucet The upper side forming part 532 may also be contacted. In the case of the wall-mounted faucet "flexible", in the fixed state, the front end of the outlet pipe f3 is arranged at the inner concave part 538; at the front end of the outlet pipe f3 of the wall-mounted faucet "flexible", along the outlet The edge of the nozzle f6 is made into a ring-shaped protruding edge portion "flange portion", and this ring-shaped protruding edge portion is joined to the inner concave portion 538 "downward surface 540". In the case of the wall-mounted faucet "Water Outlet Rotary Type", in the fixed state, the front end portion of the outlet pipe f3 contacts the rib 542 on the lower side of the inner concave portion 538.

From the viewpoint of increasing the versatility for faucets of different shapes, the aforementioned axial distance D1 "Figure 6(c)" is preferably 5 mm or more, more preferably 6 mm or more, and more preferably 7 mm or more. Considering the lead angle θ and the ideal range of the rotatable angle, the axial distance D1 is preferably less than 10 mm, more preferably less than 9 mm, and more preferably less than 8 mm.

When the water pipe connector 10 is about to fall off from the faucet f1 due to water pressure, the water pipe connector 10 will rotate along the bend of the bent portion f5. The reaction force of the contact force of the lower contact portion 132 is at the water pipe connector 10, A torque in the opposite direction is given to the rotation (rotational moment); the lower contact portion 132 suppresses the rotation of the water pipe connector 10 that occurs when the water pipe connector 10 is about to fall off the faucet f1; the lower contact portion 132 can The water pipe connector 10 is effectively prevented from falling off due to water pressure. The lower contact part 132, in the fixed state that has been installed on the wall-mounted faucet, it is ideal to contact the faucet f1 "faucet body f2" from the lower side; the lower contact part 132 is installed on the wall-mounted faucet "water outlet" In the fixed state of the "rotating type", it is ideal to touch the faucet f1 and the faucet body f2 from the bottom.

As described above, in the water pipe connector 10, since the body member 100 which is entirely integrally formed covers the outlet pipe f3 "curved portion f5" of the faucet f1, the rigidity of the body member 100 is high, and the joint parts E1 and E2 are joined together. It is easy to maintain, and therefore, the slack from the fixed state is not easy to occur. Since the first joint part E1 and the joined second joint part E2 are installed between the first joint part E1 and the pressing member 200, the pressing member 200 transmits the reaction force of the pressing force applied on the outlet pipe f3 to the first joint Between the part E1 and the second joint part E2, the contact pressure of the first joint part E1 and the second joint part E2 is increased; that is, the pressing member 200 transmits the reaction force of the pressing force applied on the outlet pipe f3 to the second 2 Joint part E2, presses the second joint part E2 to the first joint part E1. The transmission from the pressing member 200 to the second joining portion E2 may be direct transmission or indirect transmission by other members. As the body member 100 moves in the water outlet direction Dx due to water pressure, the joining force between the joining parts E1 and E2 increases, and therefore, the water pressure resistance of the related connection faucet f1 is improved.

In the foregoing embodiment, the locking member 400 having the second engagement portion E2 is a different member from the pressing member 200, but they can also be made into an integrated member; in other words, the pressing member 200 may also have the second engagement portion E2 . The pressing member 200, the rotating operation part 300, and the locking member 400 rotate integrally, and they may also be made as an integral member.

The pressing contact surfaces M1, M2 are made to change the distance from the outlet pipe f3 as the pressing member rotates; the pressing contact surfaces M1, M2 are designed around the rotation axis Z2 of the pressing member; for example, the pressing contact surface M1 and M2 may have portions that are inclined to the rotation axis Z2; in addition, even if the pressing contact surface does not have a portion that is inclined to the rotation axis Z2, for example, because the pressing contact surface is made into a stepped shape, the rotation of the pressing member can be The distance between the pressing contact surface and the water outlet pipe f3 is changed. Depending on the change of this distance, it is possible to lock the water pipe connector 10 of the water outlet pipe f3 and to receive the water outlet pipe f3.

If the axial position of the pressing member is measured at a position in the circumferential direction, the axial position of the pressing contact surface changes with the rotation of the pressing member, for example, at the circumferential center position CP of the receiving opening 108. Figure 5 (b) and (d) ", the axial position of the pressing contact surface has changed. From the viewpoint of improving the versatility of faucets with different shapes, the range of change in the axial position of the pressing contact surface at the center position CP in the circumferential direction is preferably 5 mm or more, more preferably 6 mm or more, and 7 mm The above is more ideal. Considering the lead angle θ and the ideal range of the rotatable angle, the range of change in the axial position of the pressing contact surface in the circumferential center position CP is preferably 10 mm or less, more preferably 9 mm or less, and 8 mm or less It's more ideal. In the aforementioned pressing contact surface M1 and the pressing contact surface M2, the magnitude of this change is slightly equal to the aforementioned axial distance D1.

As shown in FIG. 9, the rotation control part 142 is fixed to the body member 100, and the rotation control part 142 becomes a part of the body member 100 and is formed integrally. The rotation control part 142 controls the lever part 304 to rotate to the faucet f1 side, and prevents the lever part 304 from hitting the faucet f1 "rotating handle f4". The first part 144 prevents the rotating operating part 300 from over-rotating and the fixed state is released; the second part 146 orients the notch part 212 of the pressing member 200 toward the receiving opening 108 side to enable the receiving of the water outlet pipe f3.

The locking member 400 having the second engagement portion E2 has a structure capable of moving at the first position where the second engagement portion E2 and the aforementioned first engagement portion E1 are engaged, and the second position where the engagement is released, thereby preventing The operating force of the rotation operation against the engagement of the engagement portions E1 and E2 becomes excessive. By braking the second engaging portion E2 of the braking member 500 at the aforementioned first position, the engagement of the engaging portions E1 and E2 is maintained, and it is not easy to loosen even when there is no water pressure. Since the locking member 400 and the pressing member 200 are made of different members, for the pressing member 200, the locking member 400 can be made into a movable structure. If the lead angle of the pressing contact surface is 10° or more or more, the locking operation becomes easy; in addition, even if the lead angle is large, the rotation stop motion of the joint parts E1 and E2 is not easy to loosen. With a large lead angle, even if the rotatable angle of the rotating operating part 300 is below 300°, it can correspond to multiple faucets. Also, because the rotating angle of the rotating operating part 300 is below 300°, the lever part 304 hits The circumstance of the rotating handle f4 of the faucet f1 can be avoided. The rotatable range of the rotating operation part 300 is limited so that the circumferential position of the lever part 304 does not reach the aforementioned circumferential center position CP "refer to FIGS. 5(b) and (d)".
