Description

[Detailed description of the invention] This invention relates to a closing operation mechanism for a gas kock.

BACKGROUND ART Recently, with improvements in building materials and advances in construction technology, the floor and wall thicknesses of buildings have become extremely thin. Therefore, there is a demand for lower height gas containers that are embedded in the floor or wall.However, conventional gas containers of this type are as described in Publications No. 52-21623 and No. 18594 of 1983. The disadvantage is that the structure is complicated because an intermediate member or control ring is interposed between the closure built into the kotta body and the operating knob to lock the closure in the closing position and restrict rotation. Also, the height of the entire pot increases, making it impossible to meet the above requirements.

This idea eliminates the conventional intermediate member, restriction ring, etc., directly engages the operating knob and the closure, and creates a locking structure by locking when closing the closure and restricting the rotation of the closure outside the operating knob. The purpose of the present invention is to provide a gas tank that meets the above-mentioned demands by simplifying the system and reducing the overall height of the tank.

In order to satisfy the above objectives, this invention was constructed as follows.

That is, this invention loosely inserts the non-circular slot of the operating knob into the non-circular shaft of the closure built into the Kotoku body so that it can slide up and down, and also compresses a coil spring between the closure and the operating knob. An annular frame plate loosely fitted around the outer periphery of the knob is fixed to the upper side of the Kotoku body, and its lower surface supports the annular flange protruding from the lower end of the outer periphery of the operating knob. A gas bottle closure comprising a locking protrusion that fits into a notch provided in the annular frame plate at the closing position of the closure, and a stopper protrusion protruding from the outer periphery to stop the closure at the opening position. It is an operating mechanism.

Since this device has the configuration described above, when the bottle is closed, the locking protrusion provided on the operating knob fits into the notch of the annular frame plate, so there is no risk that the operating knob may accidentally rotate and open the bottle. Not at all. When opening the bottle, push down the operating knob against the coil spring, and the locking protrusion of the operating knob will come out of the notch in the annular frame plate.
The bottle can be opened by rotating the operating knob, and the stopper protrusion provided on the operating knob comes into contact with the bottle body when the closure is in the opening position, making it stable. When the operating knob is turned to close the cap, the operating knob is pushed up by the coil spring at the closing position of the closure, and the locking protrusion fits into the notch of the annular frame plate and is locked.

In particular, in this invention, the operating knob and the closure are directly engaged, and the locking at the time of closing and the rotation restriction of the closure are performed outside the operating knob, so the closure structure can be extremely simplified. The overall height can be reduced.

Next, in the drawings for explaining an embodiment of this invention, 1 is a lock body, 2 is a closure rotatably housed in the lock body 1, and a non-circular slot 5 of an operating knob 4 is attached to its non-circular shaft 3. is loosely inserted so that it can freely slide up and down, and a coil spring 6 is compressed between the closure 2 and the operation knob 4. 7 is an annular frame plate that is loosely fitted around the outer periphery of the operating knob 4, and is fixed to the upper side of the Kotoku main body 1 with screws 8;
An annular flange 9 protruding from the lower end of the outer periphery of the operating knob 4 is supported on its lower surface. Locking protrusions 10, 10' are symmetrically protruded from the upper surface of the annular flange 9, and notches 11, 11' into which the locking protrusions 10, 10' fit into the closing position of the closure 2 are formed in the annular frame plate. It is provided in 7.
Further, a stopper protrusion 12 is provided on the circumferential side of the annular flange 9 to abut against the main body 1 at the opening position of the closure 2 when the operating knob 4 is rotated, thereby limiting the rotation angle. 13 is a gas pipe port, 14 is a hose connection port, 1
5 is a gas passage, and 16 is an operating lever connected to the operating knob 4, which operates a known plug removal mechanism when the operating knob 4 is slightly rotated in the opposite direction from the plug-closing position. In the illustrated embodiment, the notches 11, 11' of the annular frame plate 7 are formed to be slightly longer than the width of the locking protrusions 10, 10' so that the operating knob 4 can be rotated slightly in the opposite direction from the closing position. It is set as.
