Abstract
A positive electrode feed of a lamp holder of a double bulb miner is directly connected with a main bulb connector base, and the lower part of the connector base is connected with a minor bulb connector base by contacting with a positive electrode elastic contact in an elastic way. A negative electrode feed is connected with a switch spring by case embedded elements; both sides of the switch base are stuck tightly with two sets of spring laminations, and the spring laminations are connected with a negative electrode of the double bulb respectively. The utility model can rotate a rotary switch axis to illuminate a minor bulb when a main bulb is not lighted; when the glass was broken, the main bulb connector base bounces to disengage from the negative electrode and the minor bulb connector base disengage from the positive electrode because of absolution of the pressure; thus, both the main and minor bulbs can cut power ahead.
Description
Affiliated technical field
The utility model belongs to the portable illumination device group in International Classification of Patents, promptly F21L is relevant with two bulb holder of miner's lampe especially.
Background technology
Public mine lamp, the overwhelming majority is the single filament lamp holder.Bulb and lamp surface glass are close to, and when glass was smashed, the bulb pressured state was removed, and circuit contact disconnects in advance, with anti-gas explosion; Power line is drawn directly over lamp holder in addition, can avoid drawing bumping, and this is the advantage of this type of lamp holder.But the single filament lamp holder just can't provide new illumination in mine behind filament blow.In view of the above, also produced two lamp holders, but can not satisfy standard-required, therefore do not apply.
The utility model content
The purpose of this utility model is to provide a kind of two bubble holder of miner's lampe.When the main bulb fracture of wire, can light secondary bulb behind the rotary switch axle and new illumination is provided.When lamp surface glass was smashed, major and minor bulb all can leading circuit-breaker.
It is as follows to disclose new technical scheme:
A kind of two bubble holder of miner's lampe comprises lamp head ring, lamp surface glass, two bubble reflector, lamp head shell, main bulb and secondary bulb at least, it is characterized in that:
The junction block of positive source inlet wire and main bulb links to each other, and junction block is by linking to each other with the junction block of secondary bulb with the Elastic Contact of anodal spring leaf in the bottom again;
The power cathode inlet wire links to each other with the switch spring sheet through the inner inserts of lamp head shell;
The switch shaft of reversing switch passes the lamp head shell reversing switch seat inner with it and fixes, the face of cylinder of said switch base is an electric conductor, last embedding is slightly larger than the insulator of half cycle, and its both sides are close to secondary bulb negative spring sheet and bulb spring respectively, the negative pole Elastic Contact of bulb spring and main bulb.Secondary bulb negative spring sheet and secondary bulb negative pole Elastic Contact.The conducting all the time of switch spring sheet and switch base.
According to the sample of scheme trial-production, through probationary certificate, can the rotary switch axle when main bulb does not work and light secondary bulb.Smash as lamp surface glass, then the main bulb pressurized is removed, and junction block is upspring, and bulb spring and main bulb negative pole are thrown off and leading circuit-breaker.Anodal spring leaf and main bubble junction block break away from simultaneously, also make the anodal leading circuit-breaker of secondary bubble.Said switch shaft is because the effect of big half-turn insulator can be controlled a wherein bubble of two bubbles of disconnection simultaneously or conducting.

The specific embodiment
Two bubble holder of miner's lampe comprise lamp head ring 1, lamp surface glass 2, two bubble reflector 3, lamp head shell 4, main bulb 5 and secondary bulb 7 at least.
The junction block 6 of positive source inlet wire 16 and main bulb 5 links to each other, and junction block 6 is by linking to each other with the junction block 8 of secondary bulb 6 with the Elastic Contact of anodal spring leaf 14 in the bottom again;
Power cathode inlet wire 17 links to each other with switch spring sheet 11 through lamp head shell 4 inner inserts;
The switch shaft 10 of reversing switch passes the lamp head shell 4 reversing switch seats 12 inner with it and fixes, the face of cylinder of said switch base 12 is an electric conductor, last embedding is slightly larger than the insulator of half cycle, its both sides are close to secondary bulb negative spring sheet 13 and bulb spring 9 respectively, the negative pole Elastic Contact of bulb spring 9 and main bulb 5.Secondary bulb negative spring sheet 13 and secondary bubble lamp negative pole Elastic Contact.Negative pole inlet wire 17 usefulness screws 15 are fixedlyed connected with lamp head shell 4 inner inserts.
Said switch spring sheet 11 all the time with switch base 12 conductings.
