Abstract

The utility model relates to a combined explosion-proof lamp, which is characterized in that the lamp comprises a light source cavity, an electric appliance cavity and a wire connecting cavity independently disposed and connected integrally one by one. The electric appliance cavity comprises a casing I, the light source cavity comprises a casing II, wherein the two casing are connection through thread, a wiring column III is mounted within the casing II, and connection screw bolts are provided on both ends of the wiring column III. The wiring cavity comprises a wire outlet sleeve which is provided with a wiring disk of the telescopic wiring column I. The casing I of the electric appliance cavity is provided with a conductive sheet connected with the wiring column II. The wire outlet sleeve is threadingly connected with the casing I. The wiring column is in contact with the conductive sheet. The utility model ensures sealed isolation between the cavities, effectively lowers the temperature boost of the lamp, and prolong the life of the lamp.

Description

The combined type explosion-proof lamp

Technical field

The utility model relates to a kind of light fixture, relates in particular to a kind of explosion-proof lamp.

Background technology

In the existing explosion-proof industry, the general structure of explosion-proof lamp commonly used is fixed to housing with common lamp socket, is installed in the same housing with light source or ballast.As 201,302,136 1 kinds of explosion-proof lamps of Chinese patent, comprising: cap, housing and cloche; Also comprise: ballast and light source annex; Described ballast and light source annex fixed in position are on the cap inboard.

The explosion-proof lamp of this kind structure, ubiquitous problem has:

1. when the power line of common explosion-proof lamp is installed, need to dismantle many screws that outlet puts, screw drops easily, and process is loaded down with trivial details, and efficient is low.

2. the heat that light source and ballast produce after the light fixture work can be directly passed to lamp socket or power line, causes the light fixture bulk temperature too high, easily lamp socket, power line is burnt out the service life of reducing light fixture.

Summary of the invention

The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of long service life, makes installation and maintenance combined type explosion-proof lamp more easily.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of combined type explosion-proof lamp is characterized in that: have independent respectively be provided with two or two light-source chamber that connect as one, electric apparatus chamber, wire connection cavity again; Described electric apparatus chamber has housing one, and described light-source chamber has housing two, and the two is equipped with binding post three by being threaded in the middle of the housing two, and the two ends of described binding post three have attachment screw; Described wire connection cavity has lead collar, and the patchboard of retractable contact post one is housed in the described lead collar; In the housing one of described electric apparatus chamber the conducting strip that links to each other with binding post two is housed; Described lead collar is threaded with housing one; Described binding post one contacts with conducting strip.

The technical solution of the utility model can also be further perfect:

As preferably, the interior ballast line of the light source in the light-source chamber and electric apparatus chamber is fixed with the attachment screw at described binding post three two ends, and the attachment screw of ballast power line and binding post two lower ends is fixed.

As preferably, there is attachment screw the upper end of described binding post one, and described binding post one is installed in the patchboard by the spring of overcoat, and described patchboard is installed in the lead collar by jump ring.

The utility model explosion-proof lamp divides three cavitys with light-source chamber, electric apparatus chamber, wire connection cavity, and seal isolation, the heat radiation that is about to light fixture is divided into three independent sectors, area of dissipation has increased nearly 2.5 times than ordinary lamp and lantern, the space that has circulation of air between electric apparatus chamber and light-source chamber housing effectively reduces the temperature of electric apparatus chamber, improves the bulk life time of light fixture, expand the range of application of explosion-proof lamp, realized the purpose of energy-conserving and environment-protective; Ballast is used the binding post structure with being connected of power line, guarantees seal isolation between wire connection cavity and the electric apparatus chamber, only needs during terminal block lead collar is screwed out, and draws back jump ring the patchboard taking-up is got final product wiring, makes installation and maintenance more convenient.

Secondly, the utility model explosion-proof lamp is the combined type explosion-proof lamp, can as required lead collar directly be made up separately with light-source chamber and use, and reaches a kind of multiple use of light fixture.

Description of drawings

Accompanying drawing 1 is a kind of structural representation of the present utility model;

Accompanying drawing 2 is that the wire connection cavity of Fig. 1 directly makes up use schematic diagram separately with light-source chamber.

The specific embodiment

Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

Embodiment:

Combined type explosion-proof lamp as shown in Figure 1 has independent respectively be provided with two or the two light-source chamber C that connect as one, electric apparatus chamber B, wire connection cavity A again; Electric apparatus chamber has housing 1, light-source chamber has housing 29, housing 1 and housing 29 are by being threaded, binding post 38 is housed in the middle of the housing 29, binding post 38 has the copper guiding element of attachment screw for two ends, wire connection cavity A has lead collar 1, and the patchboard 2 of retractable contact post 1 is housed in the lead collar, and the conducting strip 4 that links to each other with binding post 25 is housed in the housing 1 of electric apparatus chamber B; Lead collar 1 is threaded with housing 1, guarantees that lead collar 1 and housing 1 screw in when putting in place, and two retractable contact posts 1 fully contact with conducting strip 4 on being contained in housing 6 on the patchboard 2; The light source 10 in the light-source chamber and the line of the ballast 7 in the electric apparatus chamber are fixed with the attachment screw at binding post 38 two ends, the attachment screw of ballast 7 power lines and binding post 25 lower ends is fixed, gluing in the screw thread guaranteed seal isolation between housing 6 and the housing 9 when binding post 38 was screwed into housing 9; There is attachment screw the upper end of binding post one, and binding post 1 is installed in the patchboard 2 by the spring of overcoat, and described patchboard is installed in the lead collar 1 by jump ring 3; Binding post 25 on the housing 1 also has the copper guiding element of screw, lower end fixed-ballast 7 power lines for two ends.

Only need draw back jump ring 3 during terminal block, take out patchboard 2 wiring and get final product, installation and maintenance are more convenient, more reliable.

The utility model explosion-proof lamp is the combined type explosion-proof lamp, can as required lead collar directly be made up separately with light-source chamber and use, and reaches a kind of multiple use of light fixture.
