Abstract
The present invention relates to marine explosion-proof limit switch.Switch enclosure including being built-in with switch element, the switch element is externally provided with lid and is connected with switch enclosure, the upper end of the switch enclosure is connected provided with a rotating shaft with switch element, the lower end of the switch enclosure is provided with terminals, the front end of the rotating shaft is provided with support base, the front end of the support base is provided with swing rod, and the upper end of the swing rod is provided with roller.The present invention is simple in construction, easy to operate, when external force touches roller, drives axis of rotation by swing rod and support base, so as to realize the conversion in switch enclosure between switch element contact, disclosure satisfy that different occasions are used.
Description
Technical field
The present invention relates to marine explosion-proof limit switch.
Background technology
Limit switch, also known as travel switch, it may be mounted on the object of geo-stationary or on the object of motion, when animal is close to still life, the contact of the connecting rod driving switch of switch causes the junction closure of the contact disjunction or disconnection of closure, is gone to control circuit by the change of make and break contact opening and closing state.
Total well known, when ship rides the sea, because maritime environment is more severe, wetness is than larger, and salt air corrosion ability is strong, therefore, higher to the limit switch requirement that is used on ship.
The content of the invention
Easy to use it is an object of the invention to provide simple in construction for drawbacks described above, wide using scope, corrosion resistance is strong, the good marine explosion-proof limit switch of explosion-proof effect.
It is for this technical solution adopted in the present invention：
Switch enclosure including being built-in with switch element, the switch element is externally provided with lid and is connected with switch enclosure, the upper end of the switch enclosure is connected provided with a rotating shaft with switch element, the lower end of the switch enclosure is provided with terminals, the front end of the rotating shaft is provided with support base, the front end of the support base is provided with swing rod, and the upper end of the swing rod is provided with roller.
Further, the switch enclosure and lid have brass casting to form.
Further, the support base is socketed in the front end of rotating shaft, and the side of the support base is provided with lock-screw.
Further, the front end of the support base is provided with slide bar, and the swing rod is provided with chute along its length, and the chute is enclosed on slide bar, and the front end of the slide bar is provided with locking nut.
Further, the terminals of the switch enclosure lower end are provided with indicator lamp.
It is an advantage of the invention that：
The present invention is simple in construction, it is easy to operate, when external force touches roller, axis of rotation is driven by swing rod and support base, it so as to realize the conversion in switch enclosure between switch element contact, disclosure satisfy that different occasions are used, upper-lower position swung by adjusting, position of the roller with respect to rotating shaft is realized, so as to realize stroke adjustment.
