The above-mentioned first outside left and right sides of inner casing is provided with threaded flame-proof type face, and threaded flame-proof type face outside is provided with O RunddichtringO, and shift knob is tightly connected by described threaded flame-proof type face and described O RunddichtringO and described explosion-proof tank shell wall.
As preferably, push button function and change over switch function action module are same module, only need to change an operating head and can realize button or change over switch function.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model is realized the universal design of switch and the button of explosion-proof switch press-button product, and switch and push-button design are integrated, and it is more convenient to operate, and has reduced production cost, has improved production efficiency;
(2) the utility model adopts threaded flame-proof type mode to coordinate with explosion-proof tank shell wall, and whole device can be used as a parts batch production debugging, can be applicable to the following environment of gas IIC level and dust atmosphere in the situation that cost does not increase, and degree of protection reaches IP68;
(3) the utility model increases after power assistant spring, can overcome the frictional resistance between own wt and push rod and the bush hole of push rod, flexibly reliable to guarantee operation;
(4) the utility model push button function and change over switch function action module are a kind of module, only need to change operating head and can realize button or change over switch function.
