Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gas tank used by being attached to a gas pipe.

[Prior art and its problems] In the conventional gas kettle, when the handle is assembled into the kettle body, there is no effective method for confirming whether or not it has been reliably assembled. For this reason, if the handle is installed in an incomplete state, the parts may become loose, making it impossible to rotate smoothly, the sealing performance of the closure may deteriorate, or in extreme cases, the handle may come off and the parts may become loose. I was also worried about it flying out.

As a means to solve such problems, Jikoko 58
-As with the gas kettle described in Publication No. 24059, the engaging screws were installed radially on the handle side, the fixing screw was inserted vertically into the center of this engaging screw, and this vertical engaging screw was inserted to the specified position. There is a known configuration in which when the engagement screw is correctly inserted to a predetermined position, and when it cannot be inserted, it is determined that the engagement screw is not inserted correctly and reassembly is performed.

However, in the case of this known example, the structure is such that the engaging screws are screwed in one by one, and this screwing work is troublesome, and the hole for rotating the engaging screws is exposed on the outside of the Kotuku body, resulting in a poor appearance. Another drawback is that water and dust can enter the interior through this hole. Therefore, as a gas tank without the fixing screw or the three exposed holes in the above-mentioned known example,
-24060 Publication is known, but in this known example, the positional relationship of the guide pins is not known, the position is shifted, and the handle cannot be rotated smoothly, and the guide pin is not guided by a spring. Because the pin is pushed out, there is concern that the spring may corrode and become useless.

[Purpose of the present invention] The purpose of the present invention is to provide a guide mechanism that rotatably engages between the main body and the handle, which allows the guide members attached to three locations to be attached and detached with a single touch, without damaging the appearance. We also propose a gas tank that is difficult for water and dust to enter.

[Structure of the present invention and its operation] The configuration of the present invention is as follows.

A gas passage is formed inside, an upper opening for incorporating the closure is provided in the gas passage, and a circumferential groove having a V-shaped cross section is formed on the inner wall surface of the upper opening, and a groove is formed between the circumferential groove and the outer wall surface of the upper opening. The main body of the gas kettle has a horizontal stopper screw hole, the closure for opening and closing the gas passage inside the main body, the coil spring inserted between this closure and the handle, and the circumference inside the upper opening of the main body. A body having a guide groove is inserted therein, and a vertical hole is provided in the center with female threads cut in two places, upper and lower, and a vertical hole is provided in the center, and a vertical hole is provided in the center, and a predetermined hole is provided in the body part opposite to the screw hole of the Kotuku body. a handle comprising horizontal holes each having a large diameter portion and a small diameter portion at three locations reaching the vertical hole at intervals; a guide member formed with a V-shaped slide tip that engages with the circumferential groove; and a male thread formed on a part of the outer periphery that can be screwed into the lower female thread in the vertical hole of the handle. ,
a control member having a tapered escape groove formed below the male screw and an engaging portion at its upper end that engages with a rotary tool; and a closing screw screwed into the upper female screw of the vertical hole of the handle. and a stopper which is screwed into the stopper screw hole of the main body and whose tip engages with a circumferential guide groove on the handle side.

In the gas kottoku mentioned above, the closure is built into the kettle body, the guide member and control shaft are installed in the handle side in advance, a spring is inserted between the closure and the handle, and the body part of the handle is inserted into the upper mouth of the kottoku body. The control shaft is inserted, and then the control shaft is screwed in so that the guide member projects radially through the taper of the control shaft, and this projecting part is engaged with the circumferential groove on the side of the Kotuku body to assemble the handle. Finally, install the closure screw. Further, the rotation angle of the handle is determined by screwing the stopper into the stopper screw hole.

The gas kettle assembled as described above is normally opened and closed at a rotation angle of 90 degrees, and when the handle is removed for repair or other reasons, remove the blocking screw and stopper, and use a tool to turn the control shaft and pull it up. The inner end of the guide member comes to the relief groove. As a result, an upward force is applied to the handle by the spring, and since the tip of the guide member and the circumferential groove engage with the V-shaped inclined surface, the guide member Due to the action of the letter-shaped slope, it moves backwards, that is, it slides by itself toward the center of the handle (inside the relief groove). As a result, the handle comes off from the Kotuku body.
