The utility model is by the following technical solutions:
A kind of buckle-type solar junction box, comprise: box body, plug, interior pawl, back cover, positioning seat and lid, described positioning seat comprises setscrew nut, outer lug boss and inner convex platform, outer lug boss is arranged on the outside of box body, inner convex platform is arranged on the inside of box body, the screw thread that back cover is provided with by its inside is connected with the described setscrew nut that described positioning seat is provided with, described interior pawl comprises a cylinder-shaped body, the front end beginning one claw type end of described cylinder-shaped body, described claw type end comprises some intervals and is fixedly installed fixed claw, described fixed claw comprises a fixed part and a limiting section, described fixed part is fixed on described cylinder-shaped body, described box body is provided with some decks, and described lid is provided with some fasteners, described deck comprises two the first decks and the second deck, the two ends of described second deck are connected to the two ends of two described first decks, described second deck is provided with a projection, described fastener is provided with a cavity, described projection can be snapped in described cavity inside.
Described box body is provided with draw-in groove, and described draw-in groove inside is provided with a rubber ring, and described lid is provided with an edge and can snaps onto described draw-in groove inside and abut against with described rubber ring.
To be described fixed part be bent to form to the axis direction of described cylinder-shaped body described limiting section.
A cavity is formed between adjacent two interior pawls.
The side of adjacent two described interior pawls is parallel.
The utility model has the advantages that: the utility model in use, fastener can be snapped onto deck inside now projection snap onto cavity inside, not only can tight seal clamping but also can take off easily, when conveniently reusing, simultaneously owing to there is rubber ring, can, better by lid and box body sealing, prevent the assorted bits of dust or gas from entering into inside.
Accompanying drawing explanation
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail, wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of box body in Fig. 1.
Fig. 3 is the structural representation of the interior pawl in the utility model.
Fig. 4 is the cross-sectional view of Fig. 1.
Embodiment
Embodiment of the present utility model is set forth further below in conjunction with accompanying drawing:
As Fig. 1, 2, 3 and Fig. 4 described in, a kind of buckle-type solar junction box, comprise: box body 1, plug 2, interior pawl 3, back cover 4, positioning seat 5 and lid 6, described positioning seat comprises setscrew nut 53, outer lug boss 52 and inner convex platform 51, outer lug boss is arranged on the outside of box body, inner convex platform is arranged on the inside of box body, the screw thread that back cover is provided with by its inside is connected with the described setscrew nut that described positioning seat is provided with, described interior pawl comprises a cylinder-shaped body 32, the front end beginning one claw type end of described cylinder-shaped body, described claw type end comprises some intervals and is fixedly installed fixed claw, described fixed claw comprises fixed part 33 and a limiting section 35, described fixed part is fixed on described cylinder-shaped body.
Described box body is provided with some decks 9, and described lid is provided with some fasteners 8, described deck comprises two first decks 91 and the second decks 92, the two ends of described second deck are connected to the two ends of two described first decks, described second deck is provided with a projection 93, described fastener comprises a fastener main body 81, and described fastener main body is provided with a cavity 82, and described projection can be snapped in described cavity inside.Described box body is provided with draw-in groove, and described draw-in groove inside is provided with a rubber ring 7, and described lid is provided with an edge and can snaps onto described draw-in groove inside and abut against with described rubber ring.
