Description

Antiexplosive working lamp

Technical field

The utility model relates to a kind of headlamp, in particular to a kind of Antiexplosive working lamp.

Background technique

Antiexplosive working lamp is that one kind applies to special dimension, such as the headlamp of petroleum, chemical industry, coal mine special operation condition.It can Emergency lighting evacuation with high safety when in inflammable and explosive hazardous area and environment as trail guide and power failure.

Traditional Antiexplosive working lamp is mainly by lampshade, the cavity connecting with lampshade, set on the intracorporal illuminator of chamber, luminous member The top cover of device and closed cavity forms, and offers on top cover and enters the intracorporal conduit of chamber for conducting wire.

Such portable lamp is in special operation condition, by external environment and itself it is powerful influence, inside cavity dissipate It is hot poor.Higher temperature is gathered in cavity for a long time, it is impaired to will lead to light emitting component, so that influencing it uses the longevity Life.

Field technical staff is in order to remove the intracorporal temperature of chamber, it will usually heat dissipation be arranged on the outer wall of cavity Convex ribs, however its heat dissipation effect is not obvious.

Summary of the invention

In view of the deficienciess of the prior art, the utility model provides a kind of rapid heat dissipation, prolongs the service life, structure letter Single Antiexplosive working lamp.

To achieve the above object, the utility model provides following technical solution: a kind of Antiexplosive working lamp includes lamp Cover, the cavity being connect with lampshade, the illuminator that can be electrically connected with external power supply in cavity and the control of driving illuminator illumination Product, it is characterised in that: be equipped with several extension items extended towards lampshade at one end that the cavity is connected with lampshade, respectively prolong Stretching item and extending between item has heat dissipation gap, has the heat-dissipating space being correspondingly arranged with heat dissipation gap, the lamp on lampshade Cover includes lamp shade body and the cyclic skeleton around the setting of lamp shade body outer, by several between cyclic skeleton and lamp shade body Radiating connection plate connection, space of the heat-dissipating space between each radiating connection plate, the heat-dissipating space and heat dissipation gap pair The one end answered is upper end, and the other end is lower end, the upper end conducting corresponding with heat dissipation gap, lower end and turned on outside, and upper end is under Close to the side of cyclic skeleton and turned on outside between end.

By adopting the above technical scheme, since illuminator is at lampshade, illuminator generate thermal energy by cavity bottom Portion (one end that cavity is connect with lampshade) is spread towards top, is extended between item and extension item by being arranged in the bottom of cavity Heat dissipation gap, make illuminator generate a part of heat radiated, only fraction of heat enters transit chamber in cavity Body itself implementation removes, to improve radiating efficiency, the heat dissipation time is shortened, when promoting the lighting working light sustainable and long Between use, extend the service life of control piece.The setting of heat-dissipating space and the heat-dissipating space and heat dissipation gap on lampshade It is correspondingly arranged, forms longer heat dissipation channel, further improve radiating efficiency, shorten the heat dissipation time.And on lampshade Heat dissipation channel three directions all with turned on outside, circulation is good, for accelerate radiating rate provide guarantee.

The utility model is further arranged to: cavity is connected between item by reinforcing towards the bottom end face of lampshade and each extend Muscle connection is connect, the outer surface for extending item is equipped with heat dissipation convex ribs.

By adopting the above technical scheme, the setting of strengthened connection bar can prevent from extending item deformation and bending, and reinforce connection The bottom of cavity is isolated into several regions by the setting of muscle, so that reducing heat enters the intracorporal speed of chamber, uses up heat Amount is removed in heat dissipation gap location.The setting for extending the outer surface heat dissipation convex ribs of item can make in a part of heat extended at item It can be shed by extending an ontology.

The utility model is further set to: the junction of cavity and lampshade is equipped with installation protrusion, opens in installation protrusion Equipped with spliced eye, the edge for installing protrusion is evenly equipped with several connection lugs fixed for screw, and the lampshade is convex towards the installation The one end risen is equipped with to be extended and the guide-localization column that is adapted to spliced eye towards cavity, and the joining place of guide-localization column and lampshade is set The mounting base for having and connecting lug adaptation.

By adopting the above technical scheme, on lampshade on the one hand the setting of guide-localization column can promote to implement between lampshade and cavity Connection, on the other hand can be used as heat-conducting piece, at the heat transfer to lampshade on cavity, reduce and reduce the heat in cavity. Connection lug and with the setting dismounting of the mounting base that connect lug adaptation and easy to process, reduce lampshade and cavity junction Volume keeps its cooperation more stable and compact.

The utility model is further set to: several positioning protrusion is evenly equipped on the outer peripheral surface of guide-localization column, this is fixed The outer wall of position protrusion and the inner wall of spliced eye contradict.

By adopting the above technical scheme, setting makes between guide-localization column and spliced eye using multipoint positioning in this way, when installation Angle be not in deviation, assemble it is more convenient.

The utility model is further described with reference to the accompanying drawing.
