Description

[Detailed description of the invention] This invention relates to a wall-embedded gas tank.

The conventional gas kottokku opens and closes the closure by rotating the operating knob.
Another problem was that the mechanism for removing the plug fitted into the connecting pipe portion of the Kotsuk body became very complicated.

The purpose of this invention was to solve the above-mentioned problems.The closure was opened and closed by moving the operating stick horizontally, and the plug could be removed by pushing the operating stick. , with the aim of simplifying its structure.

In order to satisfy the above object, this invention is constructed as follows.

That is, this idea is based on the closure 2 attached to the Kotuku body 1.
A pin 4 is erected on the operating member 3, and a sliding slot 7 through which the operating rod 6 of the operating member 3 passes is horizontally opened in the cover plate 5' provided on the case 5 housing the Kotoku main body 1. On the surface of the cover plate 5', a guide groove forming piece 8 of the operating rod 6 that matches the sliding groove 7 and an expanding groove forming piece 10 into which the bulging knob 9 integrated with the operating rod 6 is fitted are continuous. A groove 12 for guiding the engaging member 11 to the pin 4 inserted into the operating rod 6 is formed on the back surface of the cover plate 5', and the bulging knob 9 fits into the expansion groove forming piece 10. To remove the plug P fitted into the connecting pipe portion 15 of the plug protruding from the hole 14 provided in the cover plate 5' below the guide groove forming piece 8 by winding the spring 13 acting in the direction around the operating rod 6. pressing arm 16
This is a wall-embedded gas kettle characterized by having a passive arm 18 which is pivotally attached to the left and right sides of the kettle main body 1 by pins 17, and which is integrally connected to the pressing arm 16 and comes into contact with the tip of the operating rod 6. In the figure, 19 is a receiving piece for the spring 13, and 20 is a forming piece for the groove 12. The groove 12 is formed by a recess 21 provided on the back surface of the cover plate 5' and two upper and lower forming pieces 20. 22 is a fixing screw of the forming piece 20, 23 is a spring acting on the closure 2, 24 is a holding ring for the operating member 3, and 25 is a mounting base.

Since this device has the configuration described above, when the plug P is inserted into the connecting pipe portion 15, the pressing arm 16 is pushed, and the passive arm 18, which is integrated with the pressing arm 16, falls forward using the pin 17 as a fulcrum, and springs. Push out the operation stick 6 against the force 13. Therefore, since the bulging knob 9 protrudes from the groove forming pieces 8 and 10, if the bulging knob 9 is pinched and the operating rod 6 is moved horizontally along the sliding groove 7, the engaging member 11 and the pin 4. The closure 2 is rotated and opened via the operating member 3. Then, when the bulge knob 9 is pushed in in the "closed" position, the bulge knob 9 enters the space surrounded by the expansion groove forming piece 10, so the passive arm 18 is pushed and the pressing arm 16 moves using the pin 17 as a fulcrum. , the plug P can be removed from the connecting pipe portion 15 by pushing the tip of the plug P. Unless the plug P is inserted into the connecting pipe portion 15, the bulging knob 9 cannot be operated because it is retracted into the expansion groove forming piece 10 by the action of the spring 13. Further, at locations other than the "closed" position, the bulging knob 9 collides with the guide groove forming piece 8 and cannot be pushed in, so the plug P cannot be removed. Therefore, it is safe because there is no risk that the plug will come off accidentally.

In particular, in this device, the closure is opened and closed by horizontally moving the knob, and the plug is removed by pushing the knob, making operation easy and reliable.
This has the effect of simplifying the structure.
