Abstract
The utility model discloses an explosion-proof illumination lamp. A fluorescent lamp tube is installed in an organic glass outer cover through a non-metal left support and a non-metal right support, press blocks on two sides are pressed on a fluorescent lamp base through tightening screws, a non-metal ejection column is installed on the outer side of the right support, and jackscrews are installed between the supports and the ejection column and the organic glass outer cover. The explosion-proof illumination lamp is good in sealing performance, high in strength and convenient to maintain.
Description
Technical field
The utility model relates to a kind of lighting apparatus, especially relates to a kind of explosion-proof lighting lamp.
Background technology
Have at some the industrial and mining enterprises that explosion-proof, moistureproof and anti-flying dust willow catkins flying in the air winged insect requires, the use of explosion-proof lighting lamp is very extensive.Existing explosion-proof lamp exists poorly sealed mostly, clean inconvenience, and mechanical strength is not high, inconvenient maintenance, the power lug problems such as leak outside.Poorly sealed, easily cause flying dust willow catkins flying in the air winged insect to enter explosion-proof lamp inside, cause light fixture intolerably dirty, illuminating effect declines, and is not easy to clean cleaning.The place of particularly gathering at some flammable explosive gas, flammable explosive gas enters after lamp interior, once meet the naked lights such as electric spark, is easy to blast, abnormally dangerous.
Summary of the invention
The purpose of this utility model is: a kind of good seal, intensity explosion-proof lighting lamp high, easy to maintenance are provided.
The technical solution of the utility model is: a kind of explosion-proof lighting lamp, comprise fluorescent tube and lucite outer cover, fluorescent tube is arranged in lucite outer cover by nonmetal left supporting and right supporting, fluorescent lamp pipeline is connected with external power source by aviation plug, briquetting is equipped with in the inner side of left supporting and right supporting, holding screw is pressed on the briquetting of both sides on daylight lamp holder, nonmetal fore-set is equipped with in the outside of right supporting, between supporting and fore-set and lucite outer cover, pack jackscrew into, support is bolted on left supporting and fore-set.
Further, in left supporting, housing screw is housed, housing screw is along the axial installation of fluorescent lamp.
Further, lucite outer cover is cylindrical.
Further, aviation plug is arranged in the hole of fore-set end.
The beneficial effects of the utility model are: owing to having adopted said structure form, illuminating lamp is worked under a complete airtight environment, between supporting, fore-set and lucite outer cover, adopt very little matched in clearance, so just avoided flammable explosive gas, humid air and dust willow catkins flying in the air and winged insect to enter illuminating lamp working space.Because outer cover adopts heavy wall lucite tube, very convenient when clean, while having dirt, directly wipe with rag, cylindrical thick-walled structure has improved the mechanical strength of shell of anti-explosion lamp greatly simultaneously.Owing on the hole on fore-set, aviation plug being installed; so aviation plug is outwarded winding and is got final product the connection of disconnecting circuit in the time of maintenance; avoid the trouble that frequently connects, tears electric wire open, simultaneously due to the protection of aviation plug, avoided charged wiring to produce the danger of electric spark.The utility model has solved the poorly sealed problem of explosion-proof lamp, improves its mechanical strength simultaneously, and makes it easy to clean, and is convenient to maintenance.The utility model is applied to flammable explosive gas to be assembled, and under high humidity environment and under the serious industrial and mining area environment of flying dust, to guarantee to use safety, and is convenient to cleaning.

Detailed description of the invention
Can find out from structural representation of the present utility model shown in Fig. 1, comprise T5 fluorescent tube 4 and lucite outer cover 5, lucite outer cover 5 is cylindrical, adopts heavy wall lucite tube.Fluorescent tube 4 is arranged in lucite outer cover 5 by nonmetal left supporting 3 and right supporting 7, briquetting 6 is equipped with in the inner side of left supporting 3 and right supporting 7, the briquetting of both sides 6 is pressed on daylight lamp holder with holding screw, thereby two supports and fluorescent tube relative position are fixed, then two supportings are inserted in to the inside of lucite outer cover 5 together with fluorescent tube 4.Nonmetal fore-set 8 is equipped with in the outside of right supporting 7, between supporting and fore-set 8 and lucite outer cover 5, packs jackscrew 9 into, reinstalls fore-set 8 after connecting the power lug of fluorescent tube.Adjust after the relative position of fluorescent tube 4 and lucite outer cover 5, between left supporting 3, right supporting 7 and fore-set 8 and lucite outer cover 5, pack jackscrew 9 into, to fix compartment at the relative position axially and circumferentially.In left supporting 3, housing screw 2 is housed, housing screw 2 is along the axial installation of fluorescent tube, and fluorescent tube utilizes housing screw 2 to adjust in axial microgap.Fluorescent lamp pipeline is connected with external power source by aviation plug, and aviation plug is arranged in the hole of fore-set 8 ends, and reserved certain space holds electric wire longer between aviation plug and fluorescent lamp.The other end of the electric wire that connects fluorescent tube is welded on flange form two core aviation plugs, is installed on the end face of fore-set 8.After adjusting the direction of illumination of fluorescent lamp, support 1 use bolt 10 is fixed on left supporting 3 and fore-set 8.Fixing for the ease of installing, on supporting and fore-set, reserve seam, fixed support is stuck on seam so that install more firm.
