Description

Vertical fixed easy dismantling night navigation lamp

The utility model discloses a kind of vertical fixing night flight light fixture easy to assemble, be suitable for airport navigation at night illumination usefulness especially, belong to a kind of lighting device.

The night flight light units on airport is to guarantee that air arm night, rainy weather flight are fought, the critical facility of training, and the quality of light directly has influence on the safety of troop operation, training.The vertical fixedly night flight light fixture of military aircraft field installing at present, great majority 1 year are only with time of 1～2 month.Because light fixture is not easy to assemble, also be in the original place in operational phase not always, suffer wind, Exposure to Sunlight throughout the year, drench with rain and the destruction of humans and animals, that damages during not carrying out night-flying training is more serious.In order to guarantee that light fixture normally uses, need to send the special messenger to make an inspection tour maintenance, but because of various forms of destructions and maintenance, full air arm uses the airport, annual with a toll of millions of units.

Main purpose of the present utility model provides a kind of protection against the tide, sealing, easy-to-dismount vertical fixedly night flight light fixture, and secondary objective provides a kind of moisture resistance, water-fast easy to assemble vertical fixedly night flight light fixture.

Technical solution of the present utility model is, it is by constituting with the lamp holder 15 of easy extension bar 13 with case lid 11 that this easy extension bar joins.Its special character is, the bottom of described easy extension bar 13 is designed to like mushroom-shaped, and its outside is and its clamp nut that closely contacts 14.The container 8 that entrance hole is left in upper opening, bottom has been set up at the middle part of described case lid 11, in this container, is provided with socket 2 and plug 5.Socket 2 is fixed on the diapire of container 8, and plug 5 is fixed on the mushroom the base of a fruit of easy extension bar 13, and the container 8 opening end walls outsides and clamp nut 14 are for being threaded.

The conductive pole of the socket 2 in the technical program in the container 8 is positioned at the cavity of porcelain pedestal, is provided with between the two wiring nuts of two conductive pole lower ends on the pedestal of porcelain dividing plate 7, two conductive poles upper end and establishes isolation channel 9.Two conductive pole parts of plug 5 are positioned at the cavity of porcelain pedestal, are provided with between its two wiring nut and establish the porcelain dividing plate 10 that the isolation channel 9 with socket 2 matches between porcelain dividing plate 6, the two conductive pole exposed parts.Two conductive pole creep age distances of socket 2 are not less than 32mm, and the creep age distance of conductive pole and base bottom wall is not less than 12mm, and the creep age distance of 5 liang of conductive poles of plug is not less than 29mm, and the creep age distance of conductive pole and pedestal upper wall is not less than 12mm.

Because easy extension bar of the present utility model lower end is designed to mushroom-shaped, container has been set up at case lid 11 middle parts, establish socket, plug in the container, establish the porcelain dividing plate in socket, the plug, increased the creep age distance between the conductive pole, make it compared with prior art, have protection against the tide, moisture resistance, water-fast, sealing, easy-to-dismount characteristics.

Accompanying drawing and drawing explanation.

Fig. 1-structural representation of the present utility model.

Wherein: 1-nut, 2-socket, 3, the 4-conductive pole, 5-plug, 6,7,10-porcelain dividing plate, 8-container, 9-isolation channel, 11-case lid, 12-rubber cushion, the easy extension bar of 13-, 14-clamp nut, 15-lamp holder.

Provide embodiment below in conjunction with accompanying drawing, be used for further specifying the utility model.As shown in the figure, the upper end of lamp holder 15 and easy extension bar 13 is for being threaded, and the bottom of this easy extension bar is established circular cavity like mushroom-shaped in the mushroom base of a fruit, and the outside of easy extension bar is and its clamp nut that closely contacts 14.Container 8 its perisporiums at case lid 11 middle parts downwards, extend upward certain distance, extend upward on the outer wall partly and establish external screw thread, establish wiring hole at the end of container 8, the section of porcelain socket 2 bottoms is the E font of mouth down, isolates the wiring nut of two conductive poles fully with porcelain dividing plate 7, establishes the hole at its end, be fixed on screw on the diapire of container 8, the middle part is the circular hole of isolating mutually, is conductive pole in the hole, establishes isolation channel 9 on the porcelain pedestal of two conductive poles upper end.The creep age distance of two conductive poles is 32mm, and the creep age distance of conductive pole and base bottom wall is 12mm.Be porcelain dividing plate 6 between the wiring nut of 5 liang of conductive poles of plug, the stage casing of conductive pole is positioned at the pedestal cavity, isolate with porcelain dividing plate 10 between the exposed end of conductive pole, this dividing plate just with socket 2 on isolation channel identical.The creep age distance of two conductive poles 4 is 29mm, and the creep age distance of conductive pole and pedestal upper wall is 12mm, and plug 5 upper walls are established the hole, links to each other with the base of a fruit of easy extension bar with screw.Conductive pole 3, conductive pole 4 are that diameter is the hollow cylinder of 5mm, and have the slit of 0.2mm on the conductive pole 4, so that conductive pole 4 can be inserted in the conductive pole 3, and fully contact.The wiring nut of conductive pole is done chromium plating and is handled, to prevent its oxidation.Wiring nut and feed cable on the socket 2 join, and the wiring nut of plug 5 and two leads of lamp holder 15 join.When light fixture is installed, earlier rubber cushion 12 is enclosed within the base of a fruit of easy extension bar 13 mushroom ends, then the plug on the lamp holder 15 5 is inserted in the socket 2, at this moment rubber cushion 12 is just in the upper surface of container 8 perisporiums and easily between the extension bar mushroom lower surface, clockwise rotate clamp nut, make on its perisporium that is screwed into container 8 openends, make lamp holder 15 and case lid 11 firm being connected as a single entity, at this moment lamp just can normally use.When need unload lamp holder, then rotate counterclockwise clamp nut, make clamp nut break away from the perisporium of container, last hand lamp head 15 makes plug 5 disengaging sockets 2, after whole light fixture shifts out from container 8, standby protective cover is screwed on the perisporium of container 8 and gets final product.Owing to adopted porcelain attaching plug, socket, isolate fully by the porcelain pedestal between the conductive pole, increased between the conductive pole, the creep age distance between conductive pole and the porcelain susceptor edges, make its insulation, humidity resistance that large increase arranged.After this socket is soaked in water and is pulled out, 500 volts of test voltages, flicker free punch-through in 5 minutes, 100 watts of indirect currents of on-load are 230 volts in water, 1 hour flicker free punch-through.If increase creep age distance again, then electrical insulation capability also can improve.
