Abstract
The utility model relates to an explosion-proof lamp which comprises a lamp body, an illuminating part, a lamp panel and a lamp shade, wherein, the lamp body and the lamp panel are detachably connected, an on-off mechanical interlocking mechanism is installed in the explosion-proof lamp and comprises a control switch connected with a power supply in series and an interlocking mechanism, the interlocking mechanism is arranged above the lamp panel, and the control switch forms the opening or closing interlocking matching via the axial movement of the interlocking mechanism and the lamp panel. The on-off mechanical interlocking mechanism is installed in the explosion-proof lamp, if the hot line operation condition occurs, when an operator screws the lamp panel downwards, the interlocking mechanism immediately acts to ensure the control switch to be switched off; because the control switch is connected with the power supply in series, the whole explosion-proof lamp can be ensured to be powered off so ensure safety; when the operator screws the lamp panel upwards, the interlocking mechanism immediately acts again to ensure the control switch to be switched on, the whole explosion-proof lamp is powered on again. Thus, the utility model has the advantages that the safety factor is higher, the structure of the on-off mechanical interlocking mechanism is simple, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of explosion-proof lamp.
Background technology
Existing explosion-proof lamp is made up of parts such as lamp body, illuminating part, lamp panel, lampshades, and lamp body and lamp panel flexibly connect.Explosion-proof lamp is in "on" position in normal operation always, runs into situation about more changing the bulb, and just can open lamp panel under the situation about must formerly cut off the power supply, forbid hot line job, but, there is potential safety hazard because maloperation takes place easily for experienced shortage of operating personnel or negligence.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, provides a kind of safety coefficient higher explosion-proof lamp.
For achieving the above object, the utility model adopts a kind of explosion-proof lamp, comprise lamp body, illuminating part, lamp panel, lampshade, lamp body and lamp panel are for removably connecting, be equiped with the power on/off mechanical interlock mechanism in the explosion-proof lamp, the power on/off mechanical interlock mechanism comprises gauge tap, the link gear with power supply polyphone, and link gear is arranged on the lamp panel top, and gauge tap moves axially by link gear and lamp panel that formation is opened or closure is linked.
Link gear of the present utility model has multiple structure, be linked as long as can realize that gauge tap constitutes to be communicated with or to open by moving axially of link gear and lamp panel: 1, link gear is made up of counter-force spring, spring pressuring plate, switch head part, the upper surface close neighbour of switch head part lower surface and lamp panel, the switch head part can move vertically, the second place that it has the primary importance of the eletric button of pushing gauge tap and discharges the eletric button of gauge tap, counter-force spring and spring pressuring plate relative set; 2, link gear is the bar thick stick, and the bar thick stick is horizontally disposed with, and the centre has a pin joint, the upper surface close neighbour of bar thick stick one end and lamp panel, and the other end is pushed or is discharged with the eletric button formation of gauge tap and cooperates, and this pin joint is provided with torsion spring.
The utility model is installed the power on/off mechanical interlock mechanism in explosion-proof lamp, as the hot line job situation takes place, when operating personnel's backspin lamp panel, link gear moves at once, gauge tap is disconnected, because gauge tap is contacted with power supply, can make whole explosion-proof lamp outage, guarantee safety; When operating personnel were revolved on again with lamp panel, link gear moved once more, makes the gauge tap closure, and whole explosion-proof lamp is switched on again, so the utility model safety coefficient is higher, and the power on/off mechanical interlock mechanism is simple in structure, and is easy to operate.

Fig. 2 is the E portion enlarged drawing of Fig. 2.
Fig. 3 is the utility model example structure exploded view.
Fig. 4 is the D portion enlarged drawing of Fig. 2.
The specific embodiment
As Fig. 1,2, shown in 3, the utility model embodiment provides a kind of explosion-proof lamp, comprise lamp body 1, absorbing heat disk 2, illuminating part, lamp panel 3, lampshade, power on/off mechanical interlock mechanism 4, lamp body 1 and lamp panel 3 are for being threaded, absorbing heat disk 2 is arranged in the lamp body 1, the inner chamber of lamp body 1 and lamp panel 3 connections is separated into, following two chambers, whole power on/off mechanical interlock mechanism 4 is installed in upper surface one side of absorbing heat disk 2, power on/off mechanical interlock mechanism 4 comprises the microswitch 5 with the power supply polyphone, link gear 6, link gear 6 is by counter-force spring 61, spring pressuring plate 62, switch head part 63 is formed, switch head part 63 is " 7 " type, the upper surface close neighbour of its lower surface and lamp panel 3, eletric button 51 close neighbours of switch head part 63 upper surfaces, one side and microswitch 5, counter-force spring 61 is pressed on the upper surface of switch head part 63, spring pressuring plate 62 is located at the upper end of counter-force spring 61, switch head part 63 can move vertically, the second place that it has the primary importance of the eletric button 51 of pushing microswitch 5 and discharges the eletric button 51 of microswitch 5.
The microswitch 5 of the foregoing description constitutes to be communicated with or to open by moving axially of switch head part 63 and lamp panel 3 and is linked, it is best embodiment, also can adopt other structures, such as link gear is the bar thick stick, the bar thick stick is horizontally disposed with, and the centre has a pin joint, the upper surface close neighbour of bar thick stick one end and lamp panel, the other end is pushed or is discharged with the eletric button formation of gauge tap and cooperates, and this pin joint is provided with torsion spring.
The foregoing description makes and utilizes the mounting bracket of the interior existing absorbing heat disk 2 of explosion-proof lamp as power on/off mechanical interlock mechanism 4, also can be designed for the mounting bracket that power on/off mechanical interlock mechanism 4 is installed separately in addition.
The utility model is installed power on/off mechanical interlock mechanism 4 in explosion-proof lamp, as the hot line job situation takes place, when operating personnel's backspin lamp panel 3, link gear 6 moves at once, gauge tap is disconnected, because gauge tap is contacted with power supply, can make whole explosion-proof lamp outage, guarantee safety; When operating personnel were revolved on again with lamp panel 3, link gear 6 moved once more, makes the gauge tap closure, and whole explosion-proof lamp is switched on again, so the utility model safety coefficient is higher, and power on/off mechanical interlock mechanism 4 is simple in structure, and is easy to operate.
