Abstract
The utility model discloses a junction box for an electric energy meter, and the junction box is convenient for transport and installation and is reasonable in layout design. The junction box comprises an upper cover and a pedestal. The pedestal is provided with a connecting part. The front and lower side surfaces of the upper cover cooperate with the connecting part of the pedestal. The front side surface of the upper cover is provided with a fixture block which is bulged outwards. The connecting part is correspondingly provided with a clamping groove which is matched with the fixture block. The fixture block is clamped in the clamping tool. The pedestal is also provided with a strip-shaped flange. The bottom of the upper cover is provided with a groove which is matched with the strip-shaped flange.
Description
Technical field
The utility model relates to a kind of connection box of electric energy meter box.
Background technology
Connection box of electric energy meter box of the prior art comprises base and is arranged on the upper cover on base, base is provided with and is fixedly connected with lid, base and upper cover are the parts that independently separate, base and the upper cover of some connection box of electric energy meter box do not link together, using base and upper cover as for example brace of other accessories of integral installation with when sampling copper-manganese sheet, or be combined into one when overall with electric energy meter measure portion, mounting process is inconvenience extremely, reduced production efficiency, and upper cover easily comes off from base in transportation; The middle part that is fixedly connected with lid of some connection box of electric energy meter box is provided with the connecting portion that connects upper cover, but the design of the location layout of connecting portion is unreasonable.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of transport, the easy for installation and rational connection box of electric energy meter box of topological design.
In order to address the above problem, the utility model is by the following technical solutions: connection box of electric energy meter box, comprise upper cover and base, described base is provided with connecting portion, match with the connecting portion of base in the leading flank of described upper cover and lower surface, on the leading flank of described upper cover, be provided with outwardly fixture block, in described connecting portion correspondence, have the draw-in groove matching with fixture block, fixture block is connected in draw-in groove, on described base, be also provided with strip flange, described upper cover bottom is provided with groove, and described groove matches with rectangle flange.
The beneficial effects of the utility model are: on the leading flank due to upper cover, be provided with outwardly fixture block, the draw-in groove having on corresponding with connecting portion matches, fixture block is in draw-in groove, when upper cover is connected with base, can be first by the groove that covers be socketed on flange, upper cover is rotated to certain angle, allow fixture block move in draw-in groove, until fixture block is connected in draw-in groove.While separating upper cover and base, fixture block is connected in draw-in groove upper cover is outwards rotated to certain angle towards the opening part of draw-in groove, fixture block can be shifted out to draw-in groove, then groove is taken out from flange.Adopt the connection box of electric energy meter box of said structure, base and upper cover are done as a whole, for example brace of other accessories and sampling copper-manganese sheet are installed again, or be combined into one when overall with electric energy meter measure portion, easy for installation, improved production efficiency, and upper cover is not easy to come off from base in transportation; The position of fixture block and the design of the location layout of draw-in groove are also quite reasonable.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment
As shown in Fig. 1,2,3,4,5, connection box of electric energy meter box, comprise upper cover 1 and base 2, described base 2 is provided with connecting portion 3, match with the connecting portion 3 of base 2 in the leading flank 1.1 of described upper cover 1 and lower surface 1.2, on the leading flank of described upper cover 1, be provided with outwardly fixture block 5, in described connecting portion 3 correspondences, have the draw-in groove 6 matching with fixture block 5, fixture block 5 is connected in draw-in groove 6, on described base, 2 are also provided with strip flange 8, described upper cover 1 bottom is provided with groove 10, and described groove 10 matches with rectangle flange 8.
The convenient installation of connection box of electric energy meter box of said structure, production efficiency improves, and in transportation, upper cover 1 is not easy to come off from base 2.
As shown in Fig. 1,2,3,4,5, in order to make the measurement function of electric energy meter not be subject to the interference of dust and fog, between groove 10 and flange 8, be provided with dust washer 11, simultaneously in order to make antidusting and the anti-fog better effects if of dust washer 11, dust washer 11 adopts resilient elastomeric material.
As shown in Fig. 1,2,3,4,5, in order to facilitate fixture block 5 and draw-in groove 6 snapping in and taking out, be the inclined-plane downward-sloping with the mating surface direction of base 2 towards upper cover 1 in fixture block 5 upper surfaces, the position that draw-in groove 6 matches with fixture block 5 upper surfaces is similarly downward-sloping inclined-plane, just can cannot not make fixture block 5 snap in draw-in groove 6 by rotary upper cover because of the cooperation of flange 8 and groove 10 like this in the time snapping in and take out.
