Description
Technical field
The utility model coalmine illumination field, relates to a kind of adjustable focal length Explosion-proof miner's lamp.
Background technology
Mine lamp is exactly the eyes of ore deposit underground labour, the illumination range of mine lamp and irradiation distance very large to the performance impact of mine lamp, the explosion-proof performance of mine lamp is also evaluate the major criterion of mine lamp quality, at present, common mine lamp mainly carrys out optically focused by the reflective adjustment of reflection shield, though there is reflection shield, but there is no focal length adjustment device, do not accomplish that the distance-light of mine lamp regulates.Also the mine lamp of some adjustable focal lengths is had to be focused by lever ring or biconvex lens, the effect that these regulative modes regulate is all bad, can not get the illumination range that workman wants, this just keeps away unavoidable being with when some operation and serves trouble, so this can not make full use of electric energy and luminous energy, form unnecessary waste, likely can there is burning mixture in mine, these burning mixtures enter outer cover and very easily set off an explosion.
Utility model content
For the problems referred to above, the utility model provides a kind of adjustable focal length Explosion-proof miner's lamp, comprise bulb, reflection shield and outer cover, described outer cover inside is provided with floating lever, driving gear, gear bar, described bulb is fixed on described floating lever, described gear bar is arranged on described floating lever side, described gear bar engages with described driving gear, also comprise drive link, described driving gear is connected with described drive link one end, the described drive link other end links outer cover outside by described outer cover, outside adjustment drive link adjustable lamp light focal length.
The quantity of described gear bar is two, lays respectively at floating lever both sides.Also comprise driven gear, another of described driven gear and described tooth bar engages, and can ensure the steadily trickle movement of floating lever like this.
Also comprise explosion-proof fixed plug, described explosion-proof fixed plug is arranged on described outer cover, and explosion-proof fixed plug blocks fuel gas and enters in outer cover.
Described outer cover outside also comprises vernier knob, and described drive link links with described vernier knob through explosion-proof fixed plug.
Also comprise turning cylinder, described turning cylinder is connected with described outer cover, and rotating shaft can rotate adjustment in order to adapt to the requirement of different employee to lamp holder different angles.
Compared with prior art, the beneficial effects of the utility model are: the distance-light of mine lamp is adjustable, this avoid the light out-focus band when some operation and serve trouble, electric energy and luminous energy can be made full use of, avoid unnecessary waste, likely can be pure at burning mixture in mine, these burning mixtures do not enter outer cover, avoid the generation of explosive incident.

Fig. 2 is side view of the present utility model;
In figure: 1, driven gear, 2, floating lever, 3, turning cylinder, 4, outer cover, 5, bulb, 6, driving gear, 7, gear bar, 9, reflection shield, 10, vernier knob, 11, wiring hole, 12, explosion-proof fixed plug, 13, drive link.
Detailed description of the invention
Below the utility model is described further:
Composition graphs 1, Fig. 2, a kind of adjustable focal length Explosion-proof miner's lamp, comprise bulb 5, reflection shield 9 and outer cover 4, it is inner that electric wire is connected to outer cover 4 by the wiring hole 11 be arranged on outer cover 4, bulb 5 is in outer cover 4, to be fixed on floating lever 2, floating lever 2 is through reflection shield 9 centre bore, floating lever 2 both sides are provided with gear bar 7, gear bar 7 and driving gear 6, driven gear 1 closely engages, driving gear 6 is connected with power transmission shaft 13, explosion-proof fixed plug is arranged on outer cover, power transmission shaft 13 is connected with the outer vernier knob 10 of outer cover 4 through explosion-proof fixed plug, outer cover outer setting has turning cylinder 3, can adjust by rotary motion axle 3, in order to adapt to the requirement of different employee to lamp holder different angles.
Regulate vernier knob 10, drive power transmission shaft 13 to rotate, power transmission shaft 13 drives driving gear 6 to rotate, and gear bar rotates with driving wheel and moves, thus changes focal length, realizes distance-light conversion.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
