Description

Flame proof long-life lighting

Technical field

The utility model relates to a kind of industrial lighting device, and especially a kind of colliery, chemical plant etc. of being applicable to have flame proof long-life lighting explosive, the inflammable articles place.

Background technology

At present, colliery, chemical plant etc. have the flame proof illuminating lamp of the place use of explosive to have straight tube fluorescent lamp and incandescent lamp two big classes.Be prone to faults such as fluorescent tube, starter damage and lamp base poor contact of contacts in the use of flame proof straight tube fluorescent lamp.If starter damages, can continue after the replacing to use, but if fluorescent tube damages, must readjust two distances between the lamp base after changing new fluorescent tube each time, it is longer that the required time of fluorescent tube is changed at the scene, and light fixture often can't normally use the flame proof straight tube fluorescent lamp because of the lamp base reed follows the string after using a period of time.The flame proof incandescent lamp mainly is made up of bulb and lamp socket, and the fault that is prone in the use is mainly bulb and damages and lamp socket inner conductive bar and reed loose contact.Although the flame proof incandescent lamp is easy to maintenance, the average life of bulb was less than 1000 hours, so maintenance load is equally very big.By " safety regulations in coal mine ", the flame proof lighting must overhaul under off-position, and common a plurality of flame proof lightings are controlled by same switch, and flame proof lighting range switch has tens meters even hundreds of rice.After a certain light fixture damages, need turn off other light fixture on this circuit to its maintenance, thereby the ordinary production at scene is caused bigger influence.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of flame proof long-life lighting that can realize the separate unit outage is provided.

The technical solution adopted in the utility model is: a kind of flame proof long-life lighting, include body, lamp socket, bulb and lampshade, and described body is the housing of two sides opening, has at least one aperture on the housing of this body; Described lamp socket and lampshade are fixedly connected on the one side of described body openings, and the face that described lamp socket contacts with described body is explosion-proof, and described bulb is installed on this lamp socket, and described lamp socket is provided with a switch; Be fixedly connected with a lid on the face of described another opening of body, the face that this lid contacts with described body is explosion-proof, be installed with an electrical equipment on the inwall of this lid, be installed with a binding post on the inwall of described body, described electrical equipment links to each other with this binding post with described lamp socket with lead respectively.

Further, described body and lampshade achieve a fixed connection with tie-plate, and this tie-plate is set on the described lamp socket, have a groove on the internal diameter of described tie-plate, and the position of this groove is corresponding with the position of described switch; Described tie-plate one end is fixedlyed connected with described lampshade, the other end is provided with the trisection male half coupling, the one side of described body openings is provided with the trisection inner stopper, described tie-plate is connected with described body with described trisection male half coupling, trisection inner stopper and a location screw, and the face that described tie-plate contacts with body is explosion-proof.

Further, an end outer wall of described body is provided with suspension ring.

Further, the outer wall of described body is provided with two G holes.

The technical scheme that adopts the utility model to provide, power line inserts binding post by described aperture, links to each other with lamp socket through electrical equipment then, realizes illumination; If bulb damages, under the constantly electric situation of the total circuit of illumination, be rotated counterclockwise 60 ° of tie-plates, the switch that drives simultaneously on the lamp socket rotates counterclockwise 60 °, make tie-plate and lampshade and body break away from, cut off the internal electric source of lamp socket simultaneously, outwards extract tie-plate and lampshade, lay down the bulb of damage, change new bulb, again by the opposite order tie-plate that closes, flame proof long-life lighting operate as normal realizes the outage of separate unit light fixture, does not influence the function of other lighting device operate as normal on the circuit.The utility model both can utilize suspension ring to hang installation, also can utilize the installation that fixes of two G holes.

Description of drawings

Accompanying drawing is the structural representation of the utility model flame proof long-life lighting.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

As shown in drawings, a kind of flame proof long-life lighting, include lampshade 1, body 2, tie-plate 3, lamp socket 4 and bulb 5, body 2 is the housing of two sides opening, have at least one aperture 21 on the housing of body 2, the one side of body 2 openings is provided with trisection inner stopper 22, tie-plate 3 one ends are provided with trisection male half coupling 31, tie-plate 3 is connected with body 2 with trisection male half coupling 31, trisection inner stopper 22 and a location screw 6, the face that tie-plate 3 contacts with body 2 is explosion-proof 7, and tie-plate 3 other ends are fixedlyed connected with lampshade 1.Lamp socket 4 is fixedly connected on the body 2, and the face that lamp socket 4 contacts with body 2 is explosion-proof 8, and bulb 5 is installed on the lamp socket 4, and lamp socket 4 is provided with a switch 41.Tie-plate 3 is set on the lamp socket 4, has a groove 32 on the internal diameter of tie-plate 3, and switch 41 is connected in the groove 32.Be fixedly connected with a lid 10 on the face of body 2 another openings, lid 10 faces that contact with body 2 are explosion-proof 9, be installed with an electrical equipment 11 on the inwall of lid 10, be installed with a binding post 12 on the inwall of body 2, electrical equipment 11 links to each other with binding post 12 with lamp socket 4 with lead respectively.One end outer wall of body 2 is provided with suspension ring 13, and the outer wall of body 2 is provided with two G holes 14.
