Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a kick lever and a push-pull rod in a drain plug.

[0002]

2. Description of the Related Art Conventionally, a pop-up type drain plug 5 attached to the bottom portion 2 of a washbasin 1 of this type is attached to an attachment hole 3 formed in the bottom portion 2 as shown in FIG. A valve seat 7 is formed on an upper portion of the stopper body 6 formed in the above, and a valve body 8 is vertically movably fitted into the stopper body 6. The valve body 8 is composed of a valve head 9 at the upper end that allows the valve seat 7 to be opened and closed, and a stem 10 extending downward from the valve head 9, and the plug body 6 includes a seal member 11 and a mounting nut. It is mounted in the mounting hole 3 via 12, and a horizontal T-shaped actuating lever pipe 13 is connected to the lower portion of the stopper body 6, and the lower end of the stem 10 of the valve body 8 is attached to the actuating lever pipe 13. It is seen inside.

A kick lever 15 is inserted into the horizontal pipe 14 of the actuating lever pipe 13, and its inner end portion is inserted and connected to a connecting hole penetrating the lower end portion of the stem 10 of the valve body 8,
The kick lever 15 has a spherical fulcrum formed at the center of the kick lever 15 slidably supported by a support member 16 attached to the end of the horizontal pipe 14, and the other end thereof is extended laterally. At the same end, an adjusting tube 17 having a tubular shape that rises at a right angle upward and having height adjusting holes 18 penetrating at a predetermined interval is attached to the kick lever 15 so that the position can be adjusted in the left-right direction. There is.

Also, a pin hole 21 is formed at a predetermined position of the washbasin 1, that is, in a state of being opposed to the adjustment pipe 17 via a guide member 19 at a predetermined interval so as to be aligned with the adjustment hole 18 of the adjustment pipe 17. The pull rod 20 is inserted and hung, and the push / pull rod 20 is inserted into the adjusting pipe 17, and the pin hole 21 and the adjusting hole 1 are inserted.
The vertical positional relationship with the push rod 2 is
The height of 0 was adjusted, the push-pull rod 20 and the kick lever 15 were connected, and the valve body 8 was opened and closed by operating the push-pull rod 20.

[0005]

However, in the conventional connection between the kick lever 15 and the push-pull rod 20 of the drain plug 5, the relatively long adjusting pipe 17 is provided with the adjusting holes 18 at predetermined intervals, and Since the push-pull rod 20 is similarly configured to have the pin hole 21 formed therethrough, there is a problem that the member is uneconomical and requires a large number of processing steps, resulting in a high cost. Since the push-pull rod 20 is adjusted up and down by replacing the holes 18 and 21, there is a problem that fine adjustment cannot be performed, and up and down adjustment is performed by replacing the pin 22 in a narrow space below the washbasin 1. Therefore, there is a problem that the adjustment workability is poor.

The present invention has been made to solve the above-mentioned problems of the prior art. The kick in the drain plug allows the push-pull rod to be adjusted up and down steplessly and facilitates the adjustment work. An object is to provide a connecting structure of a lever and a push-pull rod.

[0007]

In order to solve the above technical problems, the first gist of the present invention is to open and close the valve body of the drain plug at the bottom of the basin on the push-pull rod hanging from the upper side of the basin. A connecting structure for connecting a kick lever to be operated, wherein an upper plate and a lower plate each having a through hole through which the push-pull rod is inserted are bent and formed in a substantially V shape, and a free end of the lower plate is formed. The kick lever is connected to the push-pull rod by using a connecting fitting having a fitting curved portion which is fitted to the kick lever on the side.

The second gist is that an extension piece extending from the fitting curved portion to the upper plate side is formed, and a hook hole capable of being hooked on the push-pull rod is formed in the extension piece. It is to connect the kick lever to the push-pull rod using the connecting metal fittings.

The third gist is a connecting structure for connecting a push-pull rod hanging from the upper side of the washbasin to a kick lever for opening and closing the valve body of the drain plug at the bottom of the washbasin.
An upper plate and a lower plate each having a through hole through which the push-pull rod is inserted are bent and formed in a substantially V shape, and a connection that connects the free end side of the lower plate and the free end side of the upper plate. Connecting the push-pull rod and the connecting metal fitting with the push-pull rod being inserted into each through hole of the upper plate and the lower plate using a connecting metal fitting formed in a substantially triangular shape having a piece. The kick lever is clamped in a gap formed between the pieces, and the kick lever is connected to the push-pull rod.

[0010]

In the first aspect of the present invention, the upper plate and the lower plate are bent in a dogleg shape and are formed on the upper plate and the lower plate, respectively, using the connecting fittings having the fitting curved portions. The push / pull rod can be inserted into the through hole, and the kick lever can be fitted to the fitting curved part to firmly connect the kick lever to the push / pull rod via the connecting metal fittings. The metal fitting can be formed, and the vertical movement of the push-pull rod can be easily performed steplessly via the connecting metal fitting.

Further, according to the second aspect, since the extending piece extending from the curved portion is formed with a hook hole which can be hooked on the push rod, the hook hole is hooked on the push rod to form a connecting fitting. The kick lever can be more firmly connected to the push-pull rod via the.

In the third aspect, the connecting metal fitting is formed in a substantially triangular shape at a low cost, and the push-pull rod is inserted into the through holes formed in the upper and lower plates of the connecting metal fitting. Then, since a gap is formed between the connecting piece of the connecting fitting and the push-pull rod, the kick lever is inserted into this gap,
The kick lever can be connected to the push / pull rod by sandwiching the kick lever between the connecting piece and the push / pull rod, and the vertical adjustment of the push / pull rod can be easily performed steplessly.
