Conventionally, in order to supply hot water to a fully automatic washing machine or the like, a faucet equipped with an automatic stopper mechanism that automatically stops water when the hose joint is removed may be used. For example, as shown in FIG. 4, such a water faucet is provided with a stopper 18 having a valve body portion 24 on the back end side and a contacted portion 22 on the tip end side. The stopper 18 is provided so as to be able to advance and retreat in the water discharge pipe tip 12 forming the water discharge flow path 14, and is added to the valve body 24 in a state where the water discharge pipe 11 is not inserted and connected to the hose joint 40. The valve body 24 is seated on the valve seat 16 provided in the water discharge flow path 14 by the water pressure and the urging force of the coil spring 3. When the water discharge pipe tip 12 is inserted and connected to the hose joint 40, the contacted portion 22 of the stopper 18 is brought into contact with the contact portion 72 in the opening 44 of the hose joint 40, and the entire stopper 18 is The valve body part 24 is separated from the valve seat 16 by being pushed into the back side of the water discharge pipe 11 (right direction in the figure). By holding the stopper 18 in this state, the water discharge channel 14 is maintained in an open state, and water flow from the faucet 10 side to the hose joint 40 side is ensured. On the other hand, when the hose joint 40 is removed from the water discharge pipe 11, the contact between the contact portion 72 at the back end of the opening 44 of the hose joint 40 and the contacted portion 22 of the stopper 18 is released, and the valve body The stopper 18 moves in the direction toward the distal end side of the water discharge pipe 11 (left direction in the figure) due to the water pressure applied to the portion 24 and the urging force of the spring 3, and the valve body portion 24 quickly sits on the valve seat 16 and stops water. Here, when the lock ball 46 disposed on the inner peripheral surface of the opening portion 44 of the hose joint 40 is fitted into the circumferential groove 34 formed on the outer peripheral surface of the water discharge tube tip portion 12, the water discharge tube tip portion 12 is connected to the hose joint 40. The insertion position of the water discharge pipe tip 12 with respect to the hose joint 40 is determined.

The contacted portions 22 are respectively provided on both sides of the shaft portion 20 in the radial direction and are formed in a substantially T shape in side view with the shaft portion 20 so that the spacer 70 can be contacted. Even when it comes into contact with the contact part 22, hot water is provided from the side of the contacted part 22. Further, the abutted portion 22 is formed shorter than the inner diameter of the water discharge tube tip portion 12 and is provided so as to be able to enter and exit the water discharge tube tip portion 12.
[0013]
The valve body portion 24 is provided with a flange portion 26 having a diameter larger than that of the valve seat 16 and a circumferential groove 30 in which a ring-shaped packing 28 is mounted closer to the tip of the stopper 18 than the flange portion 26. . The packing 28 is pressed against the valve seat 16 to close the water discharge passage 14. The coil spring 3 is attached to the valve body portion 24 (not shown) so as to bias the stopper 18 from the primary side to the secondary side. When the water discharge pipe 11 is not inserted and connected to the hose joint 40, the stopper 18 is urged toward the distal end of the water discharge pipe 11 by the primary water pressure and the urging force of the coil spring 3 to the valve seat 16. While the water discharge from the water discharge pipe 11 is stopped by pressure bonding, when the water discharge pipe 11 is inserted and connected to the hose joint 40, the valve seat 16 is opened by pushing the contacted portion 22, Water is discharged from the water discharge pipe 11. Thus, the auto stopper mechanism 31 is configured.
[0014]
Further, on the outer peripheral surface of the water discharge pipe distal end portion 12, a collar portion 32 around which a claw 66 of a safety lever 60 described later is locked is provided. Further, the water discharge tube distal end portion 12 distal end side than the flange portion 32 is provided. Further, a circumferential groove 34 into which a lock ball 46 described later can be fitted is formed.
[0015]
Next, the hose joint 40 will be described. As described above, the hose joint 40 is attached to the tip of the water supply hose 2, and is connected to the water discharge pipe 11 to distribute hot water to the water supply hose 2 side. The hose joint 40 is formed in a substantially cylindrical shape as a whole, and includes a fitting portion 41 to be fitted and connected to the water supply hose 2 side, and a main body 42 to which the water discharge pipe end portion 12 is fitted and connected. In addition, a plurality of mortar-shaped accommodation holes 45 having a diameter reduced toward the inside of the opening 44 are provided on the inner peripheral surface of the tip opening 44 of the main body 420, and lock balls are respectively provided in these accommodation holes 45. 46 is arranged. In addition, a circumferential groove 49 with a packing 48 interposed is provided on the inner side of the opening 44 on the inner side of the lock ball 46, and the outer surface of the water discharge pipe tip 12 inserted into the opening 44. As a result, the water tightness between the outer peripheral surface of the water discharge pipe distal end portion 12 and the inner peripheral surface of the opening 44 of the hose joint 40 is achieved.
[0016]
A slide ring 50 for pressing the lock ball 46 from the outside is attached to the outer peripheral surface of the main body 42. The slide ring 50 is biased toward the distal end side of the main body 42 by a coil spring 52 attached to the inside thereof. Further, a convex portion 54 is provided around the inner peripheral surface of the slide ring 50 on the front end side, and the convex portion 54 is positioned outside the lock ball 46 in a state where the slide ring 50 is biased toward the front end side of the main body 42. The lock ball 46 is protruded into the opening 44. On the other hand, a concave portion 56 is provided around the inner peripheral surface of the slide ring 50 closer to the tip than the convex portion 54.
[0017]
When the slide ring 50 is slid to the inner end side of the main body 42 against the urging force of the coil spring 52, when the slide ring 50 is located on the distal end side of the main body 42, the convex portion 54 inwardly opens the opening 44. The lock ball 46 pushed in is accommodated in the recess 56 described above. In this way, when inserting the water discharge tube tip 12 into the opening 44, the slide ring 50 is slid to the back end side of the main body 42 so that the lock ball 46 is accommodated in the recess 56 and the water discharge tube tip 12. The slide ring 50 is opened after the water discharge tube tip 12 is completely inserted, so that the slide ring 50 is returned to the tip of the main body 42 by the coil spring 52 and the convex portion 54 is locked. The ball 46 is re-projected into the opening 44, and the lock ball 46 is fitted into the circumferential groove 34 of the water discharge pipe distal end 12 to complete the insertion connection and positioning of the water discharge pipe 11 to the hose joint 40. It is provided as follows.
[0018]
Further, a step portion is formed between the inner end surface of the insertion portion 41 having a smaller diameter than the opening portion 44 at the back end of the opening portion 44, and this step portion originally contacts the contacted portion 22 of the stopper 18. Thus, a contact portion 72 that sufficiently opens the valve seat 16 is formed.
[0019]
Here, the stopper 18 is provided with a length that sufficiently opens the valve seat 16 if the distance from the lock ball 46 to the contact portion 72 is 24 mm. Up to 72 is provided at 25 mm. Therefore, in this connection structure 1, a synthetic resin spacer 70 is attached to the back end of the opening 44, that is, in front of the contact portion 72. As shown in FIG. 2, the spacer 70 is formed in a disk shape having an outer diameter that is substantially the same as the inner peripheral surface of the opening 44, and hot water can be passed through the circular hole. When the thickness is about 1 mm and it is attached to the inner end of the opening 44, the distance from the lock ball 46 to the spacer 70 is 24 mm. By mounting such a spacer 70, the valve seat 16 can be sufficiently opened even in the case of the hose joint 40 where the distance from the lock ball 46 to the contact portion 72 is not a predetermined length. The thickness of the spacer 70 only needs to be formed so that at least the stopper 18 is pushed in and the valve seat 16 is sufficiently opened. Therefore, as long as the connection with the hose joint 40 is not hindered. The thickness may be somewhat increased. On the other hand, if the necessary thickness is insufficient, a sufficient water discharge amount cannot be obtained. Further, if the spacer 70 having an appropriate thickness is appropriately changed and used in accordance with the length from the lock ball 46 to the contact portion 72, it is possible to deal with various sizes of hose joints.
[0020]
Further, as shown in FIG. 2, a plurality of protrusions 74 protrude from the outer peripheral surface of the spacer 70. As described above, the outer diameter of the spacer 70 is substantially the same as the inner diameter of the inner end of the opening 44, but the outer diameter including this protrusion is slightly larger than the inner diameter of the inner end of the opening 44. ing. When the spacer 70 is pushed into the opening 44, the spacer 70 is press-fitted into the opening 44 while the projection 74 is crushed, and the spacer 70 is fitted to the inner end of the opening 44. Therefore, for example, when the hose joint 40 is removed from the water discharge pipe 11 to temporarily move the fully automatic washing machine or the like or to clean the hose joint 40, the spacer 70 is displaced from the rear end of the opening 44. There is no risk of falling out of the opening 44. As a means for locking the spacer 70 at the back end of the opening 44 as described above, the outer diameter of the entire spacer 70 is slightly larger than the back end of the opening 44 in addition to the protrusion 74 as described above. Then, it may be locked by an interference fit, or may be a split ring spacer in which the outer diameter of the entire spacer 70 is slightly larger than the inner end of the opening 44 as shown in FIG. Further, a plurality of locking claws may be provided on the outer peripheral surface of the metal spacer so as to be locked and fixed to the inner wall surface of the opening 44. The spacer 70 may be formed of other materials such as synthetic resin, metal or other rubber as described above.
[0021]
In addition, a safety lever 60 is provided on the outer peripheral surface of the slide ring 50 so as to be engaged with the flange 32 of the water discharge tube tip 12 when the water discharge tube tip 12 is inserted into the opening 44. The safety lever 60 includes a support portion 62 erected from the main body of the slide ring 50, and a latch that is connected obliquely inward from the tip end of the support portion 62 to the tip end side of the shaft center of the slide ring 50. A piece 64 and a claw 66 projecting in a hook shape at the tip of the locking piece 64 in the direction opposite to the tip of the locking piece 64 are provided. The support portion 62 is formed in an arc shape with the tip end direction of the slide ring 50 as the inside, and is provided so as to be slightly elastically deformable along the axial direction of the slide ring 50. Further, a regulating piece 68 protrudes from the rear side of the support portion 62 along the support portion 64 from the rear side of the locking piece 64 toward the outer peripheral surface of the slide ring 50 main body. In the case where it is desired to elastically deform more than necessary in the direction of the back end of 50, the locking piece 64 comes into contact with the support portion 62 so that the locking piece 64 does not displace outside more than necessary. It is configured not to be easily removed.
[0022]
The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, in the above embodiment, the distance from the lock ball 46 to the contact portion 72 in the connection structure in which the water discharge pipe 11 and the hose joint 40 are positioned by fitting the lock ball 46 into the circumferential groove 34. However, the present invention is not limited to this. For example, the end of the opening 44 is brought into contact with the flange 32 of the water discharge pipe 11 to position the water discharge pipe 11 and the hose joint 40. In this case, the spacer 70 may be mounted on the basis of the distance from the end of the opening 44 to the contact portion 72, and in addition, contact from various parts that are to be positioned. The necessity of mounting the spacer 70 can be determined based on the distance to the portion 72. Moreover, in this Embodiment, although the faucet 10 connected to a fully automatic washing machine etc. was demonstrated, if it is accompanied by attachment or detachment of the hose coupling 40, the use of this faucet will not be ask | required in particular, For example, The present invention can also be applied to various faucets for garden and car wash.
[0023]
