DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIGS. 1 and 2
1 shows an embodiment in which the present invention according to claim 1 is applied to a structure for screwing and attaching a strainer 1 to a storage recess 12 formed in an attachment portion 11 such as a faucet main body. The strainer 1 has a net portion N for removing unnecessary matter such as dust between a head portion 1a exposed to the outside and a tip portion 1b inserted into the storage recess 12, and has a head portion 1a side and O-rings R, R for ensuring watertightness are mounted on the respective side peripheral surfaces of the distal end portion 1b. A female screw portion 13 is provided in the storage recess 12, and the strainer 1 is provided.
By screwing the male screw part 2 formed in
The strainer 1 is attached.

In the present embodiment, a rib 4 is projected from the head 1a of the strainer 1 and a rod member 6 for rotating operation is inserted into an opening 5 formed in the center of the rib 4. However, it features. At both ends of the rod member 6, ball portions 6 a slightly larger than the hole diameter of the opening 5 are provided for retaining, and the length of the rod member 6 is sufficiently longer than the radius of the strainer 1. As shown in FIG. 1A, the ball portion 6a at one end is brought into contact with the rib 4, and the other end is projected to the side of the strainer 1. In this state, the rod member 6 is moved as shown in FIG. By operating, the strainer 1 can be easily rotated with a small force. Therefore, the attachment / detachment operation of the strainer 1 can be performed without using a tool.

In this embodiment, the rod member 6
May be configured to be detachable from the strainer 1.
This is possible, for example, by forming the ball portion 6a only at one end.

[Second Embodiment] FIGS. 3 and 4 show an embodiment of the present invention according to the second aspect, in which the strainer 1 is inserted into the storage recess 12 of the mounting portion 11. The present invention is applied to the case of attachment. The engagement structure between the strainer 1 and the mounting portion 11 employed in the present embodiment is as follows. A convex portion 7 is provided on the side peripheral surface of the strainer 1 on the side of the head 1a. On the other hand, the attachment portion 11 is formed so as to protrude, and a cutout groove 14 having two right-angled bent portions is formed here. Then, in order to insert the strainer 1 into the storage recess 12 and move the protrusion 7 along the cutout groove 14, the strainer 1 is pushed, turned, and pushed in this order.
Operate. Finally, by fitting the cap 15 into the notch groove 14, the strainer 1 can be attached so as not to easily fall off the attachment portion 11. When removing the strainer 1, the operation may be performed in the reverse order of the above. In any case, it is not necessary to use a tool to perform the attaching and detaching operation of the strainer 1.

The watertightness between the strainer 1 and the storage recess 12 is ensured by an O-ring R. This O-ring R is mounted on the storage recess 12 as shown in FIG. As shown in FIG. 5, it is also possible to mount O-rings R, R on the head 1a side and the tip end 1b side of the strainer 1 with the net portion N interposed therebetween. Further, only one of the O-rings R may be mounted on the strainer 1 side or the storage recess 12 side.

[Third Embodiment] FIG. 6 shows a modification of the second embodiment. In the present embodiment, the notch grooves 14a and 14b are formed in the mounting portion 11 in an axisymmetric manner, and the convex portions 7a and 7a are also provided in the strainer 1 in an axisymmetric manner. And a cap 15 in each of the notches 14a, 14b.
a and 15b are fitted. With such a configuration, since the rotation operation and the push-pull operation of the strainer 1 can be performed on the convex portions 7a, 7a provided axially symmetrically, these operations are easy to perform, and there is obtained an advantage that workability is improved.

[Fourth Embodiment] In the embodiment shown in FIG. 7, the concave-convex relationship of the engagement structure provided between the strainer 1 and the mounting portion 11 is reversed. That is, the groove 8 was formed on the side peripheral surface of the head 1 a of the strainer 1, and the protrusion 16 engaging with the groove 8 was formed in the storage recess 12 of the attachment portion 11. In the present embodiment, in order to facilitate the rotation operation of the strainer 1, a rod-shaped operation assisting portion 9 is provided on the head 1a.

[Fifth Embodiment] The fifth embodiment of FIG. 8 is characterized in that a cylindrical cap C provided with an axially symmetrical handle D and a cutout groove G is attached to the head 1a of the strainer 1. When the strainer 1 is inserted into the storage recess 12, the cylindrical cap C is externally fitted to the attachment portion 11, and the notch groove G is engaged with the projection 17 provided on the outer peripheral surface of the attachment portion 11. , And the strainer 1.
Also in this example, after the strainer 1 is inserted to the depth of the storage recess 12, the notch groove G of the cylindrical cap C is filled with the cap 18 to prevent the strainer 1 from falling off.

[Sixth Embodiment] FIGS. 9 and 10 show a sixth embodiment of the present invention. In the present embodiment, after the engaging recess H is formed in the head 1a of the strainer 1 and the through hole 19 reaching the housing recess 12 is formed in the mounting portion 11, the strainer 1 is inserted into the housing recess 12. A pin-shaped locking member E is inserted into the through hole 19 and the engaging recess H. With the locking member E, the strainer 1 is prevented from coming off and turning around the attachment portion 11. In this example, a configuration is adopted in which the locking member E and the connecting portion J provided on the head 1a of the strainer 1 are connected so as not to be separated by a connecting member F such as a ball chain. When removing the strainer 1 from the mounting portion 11,
The connection member F can be easily pulled out by pulling it.

Incidentally, the embodiment of the present invention is not limited to the above-described embodiment, and does not prevent the present invention from being appropriately changed according to the situation of implementation.

[0018]

According to the present invention, the attachment and detachment of the strainer
It can be performed with little force and without using tools.
Therefore, when installed in a place where the number of times of cleaning of the strainer is high, such as a beauty salon or a barber shop, or a place where a woman frequently performs cleaning work, a great effect is exhibited.
