Abstract
The utility model relates to an explosion-proof power distribution box and solves the problems of low protective grade and inconvenience in application of a conventional electric box. The explosion-proof power distribution box comprises a plurality of junction boxes and a plurality of explosion-proof boxes, wherein each explosion-proof box comprises an upper cover and a lower cover; the lower cover is inserted into a cavity of the upper cover; the outer wall of the lower cover is in fit with the inner wall of the upper cover; and all box bodies are connected with one another through junction plates. The explosion-proof power distribution box has the beneficial effect that not only is a plane adopted by the upper cover and the lower cover sealed, but also a circumferential surface of the lower cover inserted into the upper cover is sealed, i.e. the protective grade of the conventional explosion-proof power distribution box achieves IP(International Protection)66 in a manner of seam allowance explosion isolation; the explosion-proof boxes and the junction boxes can be combined into different structures, so that the power distribution box is wider in use scope and can be applied to different occasions; and moreover, the explosion-proof power distribution box has the advantages of simple structure and convenience in installation.
Description
Technical field
The utility model relates to a kind of distribution box, is specifically related to a kind of explosion-proof electrical distribution box.
Background technology
Along with the develop rapidly of industries such as oil, chemical industry, mining industry, explosion-proof electrical distribution box produce, use in the storage, rescue more and more widely, kind is more and more.The generation that in the damp hazardous area, how to prevent the blast of explosion-proof electrical distribution box accident property has become crucial problem.Because explosion-proof electrical distribution box the time produces electric spark inevitably in work, they will cause the generation of explosion accident in case meet with the explosive gas mixture of production or rescue site, directly jeopardize national wealth and citizen's life security.Therefore, as most popular lighting, its explosion-proof technology problem already has caused people's common concern and great attention.
Existing explosion-proof electrical distribution box comprises Flameproof box, in the case switchgear, measuring instrument, protective circuit etc. can be set; Constitute low-voltage distribution equipment, Flameproof box comprises loam cake and lower cover, and its sealing is to adopt plane and the contacted flat seal in plane; Degree of protection can reach IP65, and (IP is international Protection, and 6 represent dirt close, prevents the foreign object intrusion fully; And prevent the dust intrusion fully, 5 representatives prevent that the water that sprays from immersing).But at the distribution box that is installed on ground such as deck, it is still not enough that degree of protection reaches IP65, and immersion is to the infringement of electric equipment in the time of can not effectively preventing billow.And existing explosion-proof electrical distribution box, all need a specific specification in specified occasion, to use, it is in use extremely passive to make, does not have selectivity, inconvenience.
Summary of the invention
Not high enough for having the electronic box degree of protection now in the solution background technology, and use inconvenient problem, the utility model provides a kind of explosion-proof electrical distribution box.
The technical scheme of the utility model is: a kind of explosion-proof electrical distribution box; Comprise junction box and Flameproof box; Described Flameproof box comprises loam cake and lower cover, and described lower cover is inserted in the cavity of loam cake, fits between the outer wall of described lower cover and the inwall of described loam cake; Described junction box and Flameproof box are a plurality of, and said each casing links to each other through joint cover.
As a kind of improvement of the utility model, the bottom half of described junction box and Flameproof box all outwards protrudes, and described protrusion position links to each other with screw through joint cover.
Another kind as the utility model improves, and said junction box has 6, is the T font and arranges, and described Flameproof box is 6, is distributed in the both sides of T font.
The beneficial effect of the utility model is, loam cake seals with the plane that lower cover not only adopts mutually, and lower cover is inserted into the also sealing mutually of periphery in the loam cake, promptly adopts the mode of seam flame proof, makes the degree of protection of existing distribution box reach the IP66 level.Flameproof box and junction box can be combined into different structure, make the scope of application of distribution box wider, can be applied to different occasions.And the utility model is simple in structure, and is easy for installation.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Accompanying drawing 2 is the rearview of the utility model.
The cutaway view of the single Flameproof box 2 in accompanying drawing 3 the utility model.
Among the figure, the junction box 1, Flameproof box 2, loam cake 21, lower cover 22, joint cover 3, explosion suppresion surface 4.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 combine Fig. 2, shown in 3, a kind of explosion-proof electrical distribution box comprises junction box 1 and Flameproof box 2; Described Flameproof box 2 comprises loam cake 21 and lower cover 22; Described lower cover 22 is inserted in the cavity of loam cake 21, fits between the inwall of the outer wall of described lower cover 22 and described loam cake 21, forms explosion suppresion surface 4; Described junction box 1 and Flameproof box 2 are a plurality of, and said each casing links to each other through joint cover 3.Concrete mode is that the bottom half of described junction box 1 and Flameproof box 2 all outwards protrudes, and described protrusion position links to each other with screw through joint cover 3.And said junction box 1 has 6, is the T font and arranges, and described Flameproof box 2 is 6, is distributed in the both sides of T font, makes distribution box rectangularity on the whole.The beneficial effect of the utility model is, loam cake seals with the plane that lower cover not only adopts mutually, and lower cover is inserted into the also sealing mutually of periphery in the loam cake, promptly adopts the mode of seam flame proof, makes the degree of protection of existing distribution box reach the IP66 level.Flameproof box and junction box can be combined into different structure, make the scope of application of distribution box wider, can be applied to different occasions.And the utility model is simple in structure, and is easy for installation.
Certainly in the utility model, junction box 1 can also be combined into other structures with Flameproof box 2 in the distribution box, as comprises 6 junction boxes, and 4 Flameproof boxes divide 3 row to be provided with, in the middle of classify 4 junction boxes as, all the other are symmetrically distributed in both sides.
Every technical staff's notice: though the utility model is described according to above-mentioned embodiment; But the invention thought of the utility model is not limited in this utility model; The repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
