Anode 17, switch cathode 18, the positive sleeve 19 of switch, button spring 20 is closed to form.
As shown in Figure 1-3,1 jointing one end of antenna is circular shaft, there is fluting on circular shaft, it can be by antenna reset spring 6
It is connected on fluting；Antenna resets pedestal 2 and is bolted on aircaft configuration, and one end is provided with and the matched circle of circular shaft
Hole, the other end are the axially extending cornual plate along circular hole；Antenna reset spring 6 is fixed on antenna and resets on pedestal 2.Antenna 1 connects
The connector other end is square hole, and connecting pin 4 is inserted into square hole, and connecting pin 4 has compared with ferromagnetism, section be it is rectangular, can limit
Antenna 1 processed rotates, and 4 other end of connecting pin is connected with connecting pin reset spring 7, the other end and electromagnetism of connecting pin reset spring 7
Coil 5 is connected, and electromagnetic coil 5 is fixed in the U-shaped blind hole of electromagnetic coil pedestal 3, and the U-shaped blind hole of electromagnetic coil pedestal 3 is side
Hole, opposite with the square hole of jointing and on same axis, electromagnetic coil pedestal 3 is connected by bolt with aircaft configuration.
As Figure 7-9, control button 10 is mounted in cockpit, and actuator bracket 12 passes through screw thread and 11 phase of press button box lid
Even, press button box lid 11 is connected by button spring 20 with button box body 13；Indicator light 14 is fixed on 12 bracket of actuator bracket,
Two line traps pass through the through-hole on actuator bracket and are inserted into lamp anode sleeve, 15, lamp cathode sleeve 16, and switch anode 17 is fixed
On actuator bracket 12, line trap passes through the through-hole insertion on actuator bracket and switchs positive sleeve 19；Lamp anode sleeve 15,
Lamp cathode sleeve 16, switch cathode 18, the positive sleeve 19 of switch are fixed on button box body 13.Lamp anode sleeve 15, lamp cathode
The positive sleeve 19 of sleeve 16, switch is cylinder-like structure, and line trap can slide in sleeve, and remain contact.
As shown in figs. 10-11, electromagnetic coil 5 and antenna control switch 8 are connected in series on aircraft power supply, control button 10
It is in parallel with antenna control switch 8.Aircraft electricity is connected in series to after instruction signal controlled switch 9 is in parallel with indicator light 14 with protective resistance
On source.
8 positive and negative electrode of antenna control switch is located at antenna and resets the overhanging cornual plate end of pedestal 2, the opposite day in cornual plate end
Line position, upper and lower surfaces are equipped with sheet metal, and when 8 positive and negative electrode of antenna control switch is contacted with sheet metal, switch is opened,
He disconnects situation switch.
Indicate that 9 positive and negative electrode of signal controlled switch is located at antenna and resets the overhanging cornual plate end of pedestal 2, cornual plate end is opposite
Antenna position, centre are equipped with sheet metal, and when indicating that 9 positive and negative electrode of signal controlled switch and sheet metal contact, switch is opened, other
Situation switch disconnects.
When antenna is normally opened, the positive and negative anodes of instruction signal controlled switch 9 are all contacted with the sheet metal on antenna, indicator light
Control switch 9 is opened, and by 14 short circuit of indicator light, indicator light does not work.At this point, connecting pin 4, which is connected pin reset spring 7, is pressed in antenna
It in the square hole of 1 jointing, is limited by connecting pin 4, antenna 1 is not able to rotate.
As Figure 4-Figure 6, when the effect loaded of antenna 1 deformation to a certain extent when, the positive and negative anodes of antenna control switch 8 with
Sheet metal Contact antenna control switch 8 on antenna is opened, and electromagnetic coil 5 is powered, because connecting pin 4 has magnetism, by electromagnetism
The magneticaction that coil 5 generates, connecting pin 4 can be extracted out of 1 jointing of antenna square hole, the effect meeting loaded of antenna 1
It is folded, the positive and negative anodes of antenna control switch 8 and the sheet metal on antenna separate at this time, and antenna control switch 8 disconnects, electromagnetic wire
Circle 5 power-off, connecting pin 4 be connected pin reset spring 7 be pressed into 1 jointing of antenna square hole in because connecting pin 4 be it is rectangular,
It can be just pressed into the square hole of 1 jointing of antenna after 90 degree of rotation, stablize antenna 1 in folded state.Antenna 1 folds
When, the circular shaft of 1 connector of antenna drives antenna reset spring 6 to rotate by fluting, and the deformation of antenna reset spring 6 is made to generate elastic force.
After antenna 1 folds, positive and negative anodes and the sheet metal on antenna 1 of instruction signal controlled switch 9 are separated, and indicator light control is opened
It closes 9 to disconnect, the energization of indicator light 14 lights prompt pilot's antenna 1 and is in folded state.When needing using antenna, pilot is pressed
Lower control button 10, press button box lid 1, actuator bracket 12 downwards, drive switch anode 17 to contact with switch cathode 18 downwards, control
Switch 10 is opened.Since line trap all uses sleeve connection, remain that contact is conductive in motion process.
Control switch 10 is opened, and electromagnetic coil 5 is powered, because connecting pin 4 has compared with ferromagnetism, is generated by electromagnetic coil 5
Magneticaction, connecting pin 4 can be extracted out of 1 connector of antenna square hole.
As Figure 7-9, antenna 1 is acted on the reset that can be opened by 6 elastic force of antenna reset spring.Pilot unclamps control and presses
Button 10, press button box lid 11, actuator bracket 12 by button spring 20 act on upwards, drive switch anode 17 upwards with switch cathode 18
It separates, control switch 10 disconnects.Electromagnetic coil 5 powers off, and connecting pin 4 is connected pin reset spring 7 and is pressed into 1 jointing of antenna
In square hole because connecting pin 4 be it is rectangular, rotation 90 degree after can just be pressed into the square hole of 1 jointing of antenna, make antenna
1 stablizes in opening state.At this point, the positive and negative anodes of instruction signal controlled switch 9 are contacted with the sheet metal on antenna 1, indicator light control
Switch 10 is opened, and the power-off of indicator light 14 extinguishes prompt pilot's antenna 1 and has already turned on reset.
Above-described embodiment is only the preferred embodiment of the present invention, is not construed as limiting the invention.Antenna connects
Head matches with connecting pin, electromagnetic coil pedestal, is not limited to square hole, rectangular, can also be other shapes, as long as connecting pin
Relative displacement does not occur with jointing.Those of ordinary skill in the art are done on the basis of not departing from the principle of the invention
Any amplification, deformation be within the scope of the invention.
