Description
Technical field
The utility model relates to a kind of explosion-proof button.
Background technology
At present, in inflammable and explosive industrial production environment, conventionally all require to use explosion-proof button, but existing explosion-proof button, adopt dynamic and static contact to coordinate triggering, there is the defects such as contact is unstable, reaction is slow, useful life is short, existing explosion-proof button of while, its internal structure is comparatively complicated, and explosion-proof performance is poor.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of simple in structure, explosion-proof performance better and trigger the explosion-proof button that reaction is faster, use safety and reliability.
For achieving the above object, the utility model provides a kind of explosion-proof button, comprise explosion-resistant enclosure, described explosion-resistant enclosure is provided with containing cavity, in described containing cavity, be equiped with sensitive switch, with for pressing the trigger equipment of microswitch push-button, described trigger equipment comprises flame proof push rod, push rod and spring, described flame proof push rod is arranged in explosion-resistant enclosure, the upper end of flame proof push rod passes outside explosion-resistant enclosure, the lower end of flame proof push rod is positioned at the containing cavity of explosion-resistant enclosure, described pressure mounting of the spring is between flame proof push rod lower end and push rod upper end, the lower surface of described push rod and microswitch push-button butt, described explosion-resistant enclosure is also symmetrically arranged with two grooves in containing cavity Wai both sides, in two described grooves, correspondence is equiped with two connection bolts respectively, each connection bolt is all connected with one end of a conducting strip, the other end of described conducting strip penetrates in containing cavity and is electrically connected to sensitive switch.
The utility model can further be set to also be provided with and water sealing on described explosion-resistant enclosure, and described in water sealing and containing cavity between by sealing gasket, isolate.Adopt said structure, setting is watered sealing and can be convenient to the parts such as described sensitive switch and be encased in containing cavity, after the parts such as sensitive switch pack into, people are watering sealing and carry out encapsulation and fix described, thereby guarantee the reliable assembling of the parts such as sensitive switch, separately described watering between sealing and containing cavity, isolating seal pad is set, can effectively avoids people to water sealing and water sealing during encapsulation and penetrate in containing cavity described.
The utility model can further be set to be also embedded with one on each groove can, by the coated sheath in the inner of connection bolt, offer a jack penetrating for wire on described sheath.
The utility model can further be set to offer the cavity inserting for described push rod upper end on the lower surface of described flame proof push rod, and described spring is installed in described cavity, the two ends of spring respectively with bottom surface and the push rod butt of described cavity.
The beneficial effects of the utility model are: adopt said structure, because the utility model employing sensitive switch carrys out trigger button, therefore compared to existing technology, it triggers, and reaction is faster, use whole service life more reliable and button is also extended.During concrete use, people press flame proof push rod, and drive push rod flexible by spring, and then realization is to the pressing of microswitch push-button, and overall structure is simple, easy to operate.In addition, on each groove, one of setting-in can effectively avoid connection bolt long-term outside exposed the coated sheath in the inner of connection bolt, eliminates safe hidden trouble; Described spring is arranged to the cavity of flame proof push rod, can makes the interlock between flame proof push rod and push rod more reliable and stable.In sum, the utility model provides a kind of simple in structure, explosion-proof performance better and trigger the explosion-proof button that reaction is faster, use safety and reliability.
The inwall that the utility model also can further be set to described explosion-resistant enclosure containing cavity is provided with projection, and on the outer circumference surface of described flame proof push rod, corresponding being provided with can form with described projection the shoulder rank of spacing butt.Adopt said structure, by described projection, coordinate with flame proof push rod Shang Jian rank, can effectively prevent that flame proof push rod from skidding off disengaging explosion-resistant enclosure.
The utility model also can further be set to coaxially be bolted with an adjustment screw on the upper surface of described flame proof push rod.Adopt said structure, the length that people can extend flame proof push rod by rotation adjustment screw, makes people press flame proof push rod convenient, and effectively improves the feel of people while pressing flame proof push rod.
