Description
The present invention relates to a kind of family life articles for use, light industrial products, relate to a kind of device of using coal gas safely, can be used for the switch of the same type on household gas main switch and other pipelines, under the switch closing state, pin, concerning town gas, pin where necessary, any unlatching be can prevent, waste or security incident caused.To naughty child or muddled old man's family is arranged, necessary.In public kitchen, can avoid neighbours in dispute and the misunderstanding used on the coal gas, the whole family leaves home the date when longer, also can pin coal gas, guarantees safety.At community water supply, on the sand filter water equipment and the public coal gas in the hospital of public place, also available device pins main switch, accomplishes timing open, regularly close, so this device, have been widely used.
Use this device, not needing or not original switch or pipeline are carried out any repacking or processing through installing, and allows the part in addition and the fit on of original switch that certain error is arranged, and does not influence effective use of this device, therefore can be used as commodity selling.
For easily manufactured, reduce cost, this device is designed to single part in addition, and the part each several part is as follows in addition: shown in figure one (a), (2) slit.Shown in figure one (b), (1) opening slot, (3) lockhole is the through hole by two layers of wall, (4) switch knob imaginary positions line.
Using method and pinning principle: switch cuts out, make switch knob vertical with pipe centerline.Put device, the top edge of switch knob is contacted with the upper wall of device inner chamber, the padlock lock ring is penetrated lockhole pin.Pitch on switch fixed block pipeline because of opening slot (1), device can not rotate.Switch knob is enclosed within the slit (2), can not rotate, and switch just can not be opened.If take off device, because of the oblique below of lockhole (3) in switch knob (4) one sides, the lower limb of switch knob will block lock ring, and lock ring has penetrated in the lockhole of device.Therefore must open padlock, take out lock ring, could on switch, take off by handle assembly, could open switch then.Design of device is used in shape, and careful consideration has been passed through in aspects such as rigidity and processing.
The material of this device can be used metal skin such as low-carbon (LC) sheetmetal or plastics etc.Adopt different moulds according to different materials, machinery and processing method, but equipment is all very simple, is suitable for the plant produced of various scales.
This device has the design of figure one, figure two, the third-class various ways of figure, and similar, principle is identical, can select for use wherein a kind of according to different materials and processing method.
