[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas cock for performing a flashing operation of a stove burner or the like by pushing and rotating an operation shaft.

[0002]

2. Description of the Related Art In a gas cock which performs a flashing operation of a stove burner or the like, a valve body of an electromagnetic valve is opened via a pilot valve by a pressing operation of an operation shaft as shown in Japanese Utility Model Publication No. 2-27328. Since it is configured to operate, there is a problem that the solenoid valve closes and the ignition operation fails unless the operation shaft is pushed down reliably.

On the other hand, in a gas cock for operating a burner such as a gas stove to blink, a rotating motion is controlled by a rotating operation of an operating shaft only to open an electromagnetic valve as disclosed in Japanese Utility Model Publication No. 60-3418. There is a conversion mechanism that converts the displacement in the direction.However, this conversion mechanism stops the rotation of the operating shaft when the rotation operation is stopped.
Since the pin is disengaged from 15 and the pin rises, the pilot valve cannot slide in the axial direction even if it is rotated again.
It is necessary to return the operation shaft once to perform the ignition operation, and there is a problem that the operation is troublesome.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to reliably push and rotate the operating shaft by rotating the operating shaft and to reliably open and set the electromagnetic safety valve.

According to the present invention, there is provided a closure rotatably housed in a cock body, a valve shaft slidably mounted in a substantially central portion of the closure so as to be slidable in the axial direction, and a lower portion on the same axis as the closure. An electromagnetic safety valve that is mounted and opened by the valve shaft, and is mounted so as to be rotatable and slidable in the axial direction on the same axis as the closing element, and to slide the valve shaft in the axial direction. An operation shaft that slides in the direction, and a joint that is mounted between the operation shaft and the closing member, always rotates integrally therewith, and is restricted in rotation by a stopper formed in the cock body. A through hole into which the lower part of the operating shaft is engaged is formed in the center, and an inclined wall is formed integrally with the through hole, and a projection that is provided in the lower part of the operating shaft and abuts in the radial direction contacts the operating hole. At least the joint stops rotating by the stopper due to rotation operation in one direction Then, the projection comes into contact with the inclined wall to forcibly slide the operating shaft in the axial direction, and the electromagnetic safety valve is opened through the valve shaft.

[0006]

[Operation] By the rotation operation by the ignition operation of the operation shaft, the protrusion of the operation shaft slides on the inclined wall of the joint to forcibly operate the operation shaft in the axial direction, and the pilot valve shaft is operated by the operation shaft. At the same time, the opening is performed by sliding in the direction, and at the same time, the opening is operated by rotating the closing member to supply gas to the burner.
