Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of explosion-proof air switch in an embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1 is refer to, Fig. 1 is the structural representation of explosion-proof air switch in an embodiment of the present invention.
The invention provides a kind of explosion-proof air switch, includes air bag 1 and starter 2, also includes explosion-proof
Water ring 3, airway tube 4, metal contact piece switch 5, motor 6, gear-driven assembly 7, lever assembly 8 and reset components 9；Explosion-proof water
Ring 3 is sheathed on the outside of air bag 1, and airway tube 4 connects with air bag 1, and airway tube 4 is connected with metal contact piece switch 5, is led
A diameter of 0.05-0.1mm of tracheae 4, metal contact piece switch 5, which is arranged on motor 6, to be used to start motor 6, and motor 6, which includes, to be turned
Axle, gear-driven assembly 7 includes gear and the rack engaged with gear, gear are arranged in rotating shaft, and lever assembly 8 includes
Lever and the strong point being connected with lever rotation, one end of lever are force side apart from the less one end of the strong point, lever
One end is force side apart from the larger one end of the strong point, and force side offsets with rack, and force side offsets with starter 2, reset portion
Part 9 offsets with force side and is oppositely arranged with rack.
Based on said structure design, the course of work of the invention is：
By the explosion-proof water ring 3 of operating personnel's manual pressure, explosion-proof water ring 3 extrudes air bag 1, air bag 1 after being pressurized
