Abstract
The utility model relates to a marine explosion -proof limit switch. Including the built -in switch box that has switch element, the outer with lid of switch element is connected with the switch box, the upper end of switch box is equipped with a pivot and is connected with switch element, the lower extreme of switch box is equipped with the wiring end, the front end of pivot is equipped with the supporting seat, the front end of supporting seat is equipped with the pendulum rod, the upper end of pendulum rod is equipped with the gyro wheel. The utility model discloses simple structure, convenient operation when the gyro wheel is touched to external force, rotates through pendulum rod and supporting seat drive pivot to realize the conversion between the interior switch element contact of switch box, can satisfy different occasions and use.
Description
Technical field
This utility model relates to marine explosion-proof limit switch.
Background technology
Limit switch, it is also called travel switch, may be mounted on the object of geo-stationary or on the object of motion, when animal is close to still life, the connecting rod of switch drives the contact of switch to cause the contact disjunction of Guan Bi or the junction closure of disconnection, the change of make and break contact opening and closing state go control circuit.
Always well known, when ship rides the sea, owing to maritime environment is relatively more severe, wetness is relatively larger, and salt air corrosion ability is strong, therefore, requires higher to the limit switch used on ship.
Utility model content
For drawbacks described above, the purpose of this utility model is in that to provide simple in construction, easy to use, uses scope wide, and corrosion resistance is strong, the marine explosion-proof limit switch that explosion-proof effect is good.
Be the technical scheme is that by this this utility model
Including the switch enclosure being built-in with switch element, described switch element is externally provided with lid and is connected with switch enclosure, the upper end of described switch enclosure is provided with a rotating shaft and is connected with switch element, the lower end of described switch enclosure is provided with terminals, the front end of described rotating shaft is provided with supporting seat, the front end of described supporting seat is provided with fork, and the upper end of described fork is provided with roller.
Further, described switch enclosure and lid all have brass casting to form.
Further, described supporting seat is socketed in the front end of rotating shaft, and the side of described supporting seat is provided with lock-screw.
Further, the front end of described supporting seat is provided with slide bar, and described fork is provided with chute along its length, and described chute is enclosed within slide bar, and the front end of described slide bar is provided with locking nut.
Further, the terminals of described switch enclosure lower end are provided with display lamp.
The utility model has the advantages that:
This utility model simple in construction, easy to operate, when external force touches roller, axis of rotation is driven by fork and supporting seat, thus the conversion realized in switch enclosure between switch element contact, it is possible to meet different occasions and use, swing upper-lower position by adjusting, realize the position of roller phase countershaft, thus realizing stroke adjustment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Figure 1 is switch enclosure, 2 is lid, 3 is rotating shaft, 4 is terminals, 5 is supporting seat, 6 is fork, 7 is roller, 8 is lock-screw, 9 is chute, 10 is locking nut, 11 is display lamp.
