Abstract

The utility model relates to a meter case of a three-phase electric energy meter, which comprises a cover body, a bottom case matched with the cover body, and a tail cover connected with the cover body and the bottom case, wherein the tail end of the cover body is provided with a blocking hook; and a blocking piece is arranged on the bottom case at the position corresponding to the blocking hook; The cover body and the bottom case of the meter case of the three-phase electric energy meter are connected with each other by the blocking hook and the blocking piece; when being needed to be separated from each other, the cover body and the bottom case only need to have relative motion, so that the safety performance of the meter case is improved, the service life of the meter case is prolonged, and the meter case is more convenient to use due to the design; furthermore, the available space in the meter case can be enlarged, and the internal design of the meter case is optimized.

Description

A kind of three-phase electric energy meter watchcase

Technical field

The utility model relates to a kind of three-phase electric energy meter watchcase.

Background technology

Layout in the existing drain pan concave shaped space is reasonable inadequately; In order to settle ammeter core, control main board and power panel, cause the ammeter shell volume excessive, because mainboard and power panel are fixed; The turnover lead is arranged on the end side surface of base on the base, brings certain influence for the safety of products performance.

In the cooperation of lid and drain pan, existing design is to adopt from the top down to open or close, and such design meeting seriously should serviceable life, and security performance also can have a greatly reduced quality, and often causes the fastening place to be ruptured because of some factor and makes product rejection.

The utility model content

The technical matters that the utility model will solve provides a kind of safety, high life and three-phase electric energy meter watchcase attractive in appearance.

The content of the utility model be it comprise lid, with drain pan and the tail-hood that is connected with lid and drain pan that lid cooperates, said lid end is provided with grab, is provided with fastener with the corresponding position of grab on the said drain pan.

The beneficial effect of the utility model is; The lid of the utility model connects together with fastener through grab with drain pan, when needs separate, both is done relative motion get final product; Such design has increased the security performance and the serviceable life of the utility model; Use convenient, but and strengthened the inner usage space of the utility model, optimized indoor design.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is the structural representation of the grab of the utility model.

In the drawings, 1 lid, 2 drain pans, 3 tail-hoods, 4 grabs, 5 fasteners.

Embodiment
