Technical Field

[0001] The utility model relates to a remote magnetically controlled switch and belongs to the field of remote control. Background Art

[0002] The remote magnetic control switch of the aircraft refueling truck is a switch device used for remote control of the refueling truck. It uses magnetic control technology to achieve remote control of the start and stop of refueling, as well as unmanned flow cut-off protection, and other equipment configurations to ensure that the pressure at the end of the hose at the aircraft tank port does not exceed the standard, providing a more convenient and safe refueling operation. The bottom of the remote magnetic control switch of the aircraft refueling truck is fixedly connected to a spiral wire.

The reed assembly 6 has a switch function, but uses a magnetic steel sheet 51 made of magnetic material as a mechanism to trigger the switch. The reed assembly 6 is usually composed of two metal reeds, one of which is fixed in an insulating sleeve of magnetic material, called a reed, and the other is a magnetic material, called a trigger magnet or a magnetic nail. When the trigger magnetic steel sheet 51 approaches the reed inside the reed assembly 6, the reed will bend due to the action of the magnetic force, turning on the switch. When the trigger magnet leaves the reed, the reed rebounds and turns off the switch.

[0036] When in use, the socket 82 is prefabricated and installed on the refueling vehicle, and the plug 81 and the socket 82 are plugged and connected. The operator holds the handle body 1. When the switch needs to be controlled, the pressure plate 2 is manually pressed to tilt one end. Under the action of force, the pressure plate 2 is turned downward with the rotating shaft as the rotation center. While turning, the pressure rod 4 is pressed, and the spring 3 is squeezed and contracted. The magnetic steel combination 5 on the pressure plate 2 is close to the reed combination 6, and the reed combination 6 is triggered. The triggered switch signal is transmitted to the magnetic control refueling program controller of the refueling vehicle through the spiral wire combination 7 and the aviation plug combination 8, so as to realize the remote control of refueling and unmanned flow interruption protection, and other equipment configurations are used to ensure that the pressure at the end of the hose at the aircraft fuel tank port does not exceed the standard. When the hand is released, the spring 3 resets and rebounds, driving the pressure plate 2 to turn upward with the rotating shaft as the rotation center. While turning, the magnetic steel combination 5 on the pressure plate 2 is in line with the reed combination 6, and the reed combination 6 is closed.
