2. Description of the Related Art Conventionally, actuating tools for drain cocks include
As disclosed in Japanese Patent Publication No. 2147, etc., a support shaft having a drain port plug lid fixed thereto is provided in a guide cylinder in which an upper opening of a bottomed cylindrical body vertically suspended from the drain port is covered with a lid. A thrust lock mechanism is inserted into the guide cylinder so as to be vertically movable and alternately locks and unlocks the support shaft by vertically moving the support shaft, and the thrust lock mechanism is attached to the support shaft. A fixed ring, a rotating ring that is rotatably fitted between a guide portion formed in the guide cylinder, and a protrusion formed on a support shaft portion above the fixed ring. It has been known. Such a prior art thrust lock mechanism locks the rotating ring, which is pushed up by the fixing ring when the operating lever is pressed down for the first time, into the guide portion and opens it, and guides the guide ring with the fixing ring when the operating lever is pushed down for the second time. The rotating ring (saw tooth of the rotating ring), which is released from being locked to the part, slightly engages and rotates the guide part (the saw tooth of the guide part) and drops. The stopper is closed by releasing the engagement with the guide part. . At that time, the sliding wire (plunger) in the release that pushes up the rotating ring will always return to the original position by the resilience of the return spring built in the operating part when the pressing force of the operating lever is released. Has become.

[0003]

By the way, such a drain cock operating tool leaks water into the inside of the guide cylinder by long-term use to generate water deposits and the like, which may cause the sliding resistance of the support shaft. The water residue adheres to the rotating ring and the guide portion, and hinders the rotating and falling of the rotating ring. In this case, even if the fixing ring is pushed up by the second operation, the support shaft stops at the pushed up position and does not drop,
The cap may be left open without being plugged, or it may drop halfway and leak completely.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to surely support the support shaft without being affected by the sliding resistance of the water residue generated inside the guide cylinder. It is an object of the present invention to provide a drain cock actuating tool which is pushed down to close in a watertight manner.

Next, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show a first embodiment of the drainage plug actuating device of the present invention, and FIG. 3 shows a second embodiment thereof. Reference symbol A is a drainage plug operating tool.

First, a first embodiment will be described. The drainage plug operating tool A has an upper end of the support shaft 1 attached to the lower surface of a plug lid 101 covering the drainage port 100, and this support shaft 1 is
0, and is vertically movably inserted into a guide tube 2 fixed therein, and the support shaft 1 is returned to the operation unit 3 by a return spring (not shown).
The plunger is moved up and down by a lifting operation of a release (specifically, a plunger 33a at the tip of a sliding wire 33 in the release 23) which resists the resilience of the guide tube 2 through the thrust lock mechanism 4 by the up and down movement. And a basic structure for alternately locking and unlocking the support shaft 1 at the time of opening. As is well known, a return spring (not shown) of the drainage plug operating tool A has a function of returning the plunger 33a to its original position when the pushing operation is released.

The guide cylinder 2 includes a bottomed cylindrical body 12 and its cylindrical body.
And a lid portion 22 for covering the upper opening of the cylindrical body 12, both of which are formed of a desired synthetic resin material (for example, polyacetal resin or the like), and a mounting flange 32 provided around the upper end of the cylindrical body 12.
Is fixed to a mounting piece 100 ′ protruding inward from the inner peripheral surface of the drain port 100 in a cross shape or the like in plan view with a screw 102 and fixed to the central portion of the drain port 100.

The lid portion 22 has a shaft insertion hole 22a through which the support shaft 1 is inserted at the center thereof, and an O-ring and a V-packing which abut on the edge of the shaft insertion hole 22a with a desired seal resistance. , A U-packing or other annular sealing material 22b.

The operation unit 3 is provided at the lower end of a support cylinder 13 which is mounted in a penetrating manner on the upper edge surface of the bathtub or on a counter surface adjacent to the bathtub.
23, and a plunger guide 23a at the other end of the release 23 is screwed into the lower end of the guide cylinder 2,
One end of a sliding wire 33 that slides in the release 23 is connected to the lower end of an operating lever 43 that is loosely fitted in the support cylinder 13 so as to be able to move up and down in the vertical direction. The jar 33a is configured to be able to protrude and retract into the guide cylinder 2 from the plunger guide 23a, and the support shaft 1 is pushed up by pushing down the operation lever 43.

The stopper lid 101 has a disk shape having an area slightly larger than the rim area of the drain port 100, and is formed of a synthetic resin material (for example, a polyacetal resin) in this embodiment. A packing material 100 "is fixed to the back surface by a desired means such as adhesion, and is attached to the upper end of the support shaft 1 which is lifted by the operation of pressing down the operation lever 43.

The thrust lock mechanism 4 has a conventionally well-known structure, and includes a fixing ring 14, a guide portion 24, and a rotating ring 34. The fixing ring 14 is fixed to the support shaft 1, and has a saw-tooth shape on the upper part. Tooth 14a and several projections 14 on its side
b, the rotary ring 34 is rotatably loosely fitted on the fixed ring 14 between the projection 11 protruding from the support shaft 1 and is engaged with the serrated teeth 14a of the fixed ring 14 at the lower portion. Having the serrated teeth 34a to be stopped and several protrusions 34b on its side, the guide portion 24 is formed on the inner peripheral surface of the guide cylinder 2,
Since the fixing ring 14, the guide grooves 24b for guiding the protrusions 14b and 34b of the rotating ring 34, and the saw-tooth teeth 24a are alternately the same as in the conventional case, the operation shown in FIGS. Except for the vertical front view, it is not shown and will not be described again.

When the operation lever 43 is depressed from the water stop state shown in FIG.
The sliding wire 33 in 23 slides and pushes up the support shaft 1 with the plunger 33a. At this time, when the rotating ring 34 is pushed up onto the guide portion 24, its serrated teeth 34 a contact the serrated teeth 14 a of the fixed ring 14 and slightly rotate.
When the operating lever 43 is released, the protrusion 34b of the rotating ring 34 is released.
Engages with the saw-toothed teeth 24a of the guide portion 24 and is locked at the upper position shown in FIG. 2, and the protrusion 11 of the support shaft 1 comes into contact with the upper surface of the rotating ring 34, as shown in FIG. To lid 101
Is opened at a position away from the drain port 100. Next, when the operating lever 43 is pushed down again, the plunger 33a pushes up the support shaft 1. At this time, the rotating ring 34
When the operating lever 43 is released, the fixed ring 14 is lowered by the protrusion 14b entering the guide groove 24b of the guide portion 24. On the other hand, the rotating ring 34 slightly rotates after the serrated teeth 34a contact the serrated teeth 24a of the guide portion 24, and then the protrusions 34b enter the guide grooves 24b and descend. As a result, the stopper lid 101 closes the drain port 100, and the stopper is brought into the closed state shown in FIG.

Incidentally, the sliding resistance of the support shaft 1 is increased by water scabs and the like entering the guide cylinder 2, and even if the support shaft 1 is pushed up by the sliding wire of the release 23, it stops at the pushed up position and is operated for the second time. Even when the part 3 is pushed down, the open state may be maintained and the stopper may not be closed. The rotating ring 34 is formed of a polyacetal resin or the like which is a synthetic resin material, and is relatively light. Therefore, slight rotation of the saw-tooth-shaped teeth 34a at the saw-tooth-shaped teeth 24a of the guide portion 24 may be hindered by adhesion of water deposits and internal freezing (in the guide cylinder) due to long-term use. In order to prevent this, the support shaft return spring member 5 for urging the support shaft 1 to the predetermined position and the rotation of the rotary ring 34 in the closing direction to surely rotate the rotary ring 34 is interposed . Around the above support
