Abstract
The utility model relates to a lamp cap for miner's lamps, which is composed of a lamp cap casing, a lamp cap cover, lamp surface glass, lamp holders, a bulb, etc., wherein, the two lamp holders are arranged on a spring piece, one end of which is fixed on the lamp cap casing in the lamp cap casing, and two spring seat pieces corresponding to the lamp holders are arranged on the inner bottom surface of the lamp cap casing. A transfer switch is also arranged on the lamp cap casing. A positive pole of a power supply can be converted between the two spring seat pieces respectively, and thus, the lamp cap for miner's lamps is characterized in simple and compact structure, convenient operation, double-lamp cap insurance, benefit for safety production for under mine miners, etc.
Description
The utility model relates to a kind of lighting, especially a kind of at the illuminating mine lamp light fixture of mine current downflow.
Miners are at well operations, often need mine lamp hung over to make mine lighting usefulness on the safety cap, so that miner's safety work.The primary structure of this mine lamp is formed and is comprised lamp head shell, Cap casing, lamp surface glass and lamp socket of bulb etc. is housed, hatpin is housed on the lamp head shell is used to be suspended on safety cap, general this mine lamp for the sake of security, after preventing the lamp surface glass fragmentation, because of the work of still switching in the lamp head shell a kind of safe breaker device that easily caused fire damp blast specialized designs, this safe breaker device is by the lamp socket that bulb is housed be upturned (utilizing spring leaf), normal position it and power supply base are thrown off, in case utilize Cap casing fastening lamp surface glass to make it to compress bulb during assembling and make lamp socket contact with power supply base that lamp surface glass is broken to be opened, lamp socket will pop up immediately and return to the normal position and separate with power supply base, thus outage.But what the holder of miner's lampe of said structure generally adopted is single lamp illumination, be that a bulb only is housed in the lamp head shell, when the miner uses mine lamp in underground work, in case lamp is spoilt, just can't normally use, seriously can have influence on the safety in production of down-hole, the trouble incident that this has become that down-hole miner uses that mine lamp often runs into.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of two bulb safety miner's lamp lamp holders of changeable use are provided, and is convenient to down-hole miner and uses safely in operation process.
The purpose of this utility model is finished by following technical solution, it mainly comprises lamp head shell, Cap casing, lamp surface glass, lamp socket and bulb etc., having two lamp sockets to be loaded on an end in lamp head shell is fixed on the spring leaf of lamp head shell, the lamp head shell inner bottom surface is provided with two each spring seat slices corresponding to lamp socket, device has change-over switch on lamp head shell, the adjacent switch contact that is communicated in power supply that is connected with of change-over switch, this switch contact are between two spring seat slices and can distinguish contact spring seat sheet.
The utility model is that two lamp sockets are contained on the same spring leaf, and is with being provided with relief spring at the bottom and the lamp head shell of this spring leaf.
The utility model also on the back side behind the described lamp head shell device hatpin and charging switchgear are arranged, in addition on the sidewall of lamp head shell, offer entrance hole, device has the inlet wire clamp device on the hole.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a lamp head shell internal structure schematic diagram of the present utility model.
Fig. 3 is a change-over switch arrangement schematic diagram of the present utility model.
Below will the utility model is further introduced by accompanying drawing: the back back side of lamp head shell 1 be an inclined plane shape, upward be fixed with hatpin 3 with screw 2, on this oblique back, also offer a charging jack 4, interior device has the charging switchgear 6 of band charging contact 5, charging contact 5 is connected in the connecting bolt 7 of charging jack 4 bottoms, this connecting bolt 7 is connecting on the end limit of a copper triangular plate 8 on one side, and another side is then connecting the input electric wire of battery.The other end limit of described copper triangular plate 8 is fixed in the lamp head shell 1 by screw 9, and the 3rd end limit of triangular plate 8 is connected on the switch spring sheet 10 that is installed on the lamp head shell 1.At one end be fixed on the lamp socket spring leaf 11 of lamp head shell 1 one sides two lamp sockets 12 are housed simultaneously, on two lamp sockets bulb 13 is housed respectively, be fixed with spring seat slice 14 on lamp head shell 1 inner bottom surface below corresponding to these two lamp sockets 12, and these two spring seat slices 14 respectively are connected with spring leaf 15, between two spring leafs 15, then be mounted with above-mentioned switch spring sheet 10, on the switch of the adjacent change-over switch 16 of ining succession of the switch spring sheet cover 17, switch cover 17 is overhanging outside lamp head shell 1 and connect turn-knob 19 by switch shaft 18.Rotate turn-knob 19 and make switch shaft 18 drive the switch cover 17 that its end is connected, and contact respectively with two adjacent spring leafs 15, thereby can contact the power supply of one of two bulbs arbitrarily and make it to switch on shinny by switch cover 17 drive switch spring sheets 10.Lamp socket spring leaf 11 is connected in the negative pole of battery input electric wire, for increasing the return elasticity of lamp socket spring leaf 11, at lamp head shell 1 bottom device one turriform relief spring 20 is arranged, the upper surface of this spring 20 is tight against at lamp socket spring leaf 11, when the normal position, lamp socket spring leaf 11 upwarps, and the lamp socket 12 on the lamp socket spring leaf 11 is separated with spring leaf 14.And when being tightened with Cap casing 21 fastening lamp surface glass 22 and with screw thread in lamp head shell 1 front, lamp surface glass 22 will be pressed in bulb, thereby make lamp socket move down the spring seat slice of contact lamp socket below, connect battery this moment, at this moment will light one of them bulb.When in use, this lamp is spoilt suddenly, at this moment, as long as rotate change-over switch, switch spring sheet 16 is contacted with another spring leaf 15, another bulb and battery is connected, thereby lighted this bulb.The utility model in addition offers entrance hole 23 on a sidewall of lamp head shell 1, device has line clamping device 24 on the hole, the input line of battery is inserted from the hole and fixes with line clamping device 24, will import electric wire then and be connected in each interior tie point of lamp head shell and get final product.
Tube face described in the utility model also can be sub-packed on separately the spring leaf.
The utility model compared with prior art has simple in structurely, easy to use, and two-burner lamp is protected The danger is conducive to the characteristics such as down-hole miner safety in production.
