Plastic package for electric energy meter box

Abstract

The invention relates to a plastic seal cover member of an electric energy meter box. The cover member is characterized by comprising a plastic seal body and an unseal member. The plastic seal body comprises a plastic seal sealing body and a plastic seal head part which are integrally formed. The external surface of the plastic seal head part is provided with an annular boss. The center lines of the annular boss and the plastic seal sealing body are matched together; the inner diameter of the annular boss is equal to the inner diameter of the plastic seal sealing body. The unseal member comprises a supporting body and a cutter which is arranged at front of the supporting body. The cutter is cylindrical and the external diameter of the cutter is equal to the inner diameter of the annular boss. The front end of the cutter is provided with an indented blade. The external diameter of the supporting body is larger than the inner diameter of the annular boss. The tail end of the supporting body is provided with an inner aperture which matches a cross screwdriver head of a screwdriver. The top surface of the cutter inner chamber is provided with a needle-like part which is parallel with the center line of the top surface of the cutter inner chamber, or is provided with a sucker. The plastic seal cover member has a reasonably designed structure and is convenient and reliable to use. By use of the plastic seal cover member, the working efficiency of workers in electric power departments is significantly increased, and the inspection and maintenance work are orderly carried out.

Description

technical field [0001] The invention relates to an anti-cheating and anti-destruction device for an electric energy meter box, in particular to a plastic sealing kit for an electric energy meter box. Background technique [0002] Electric energy metering is an important work in electric energy management. Its fairness, justice, accuracy and reliability are directly related to the interests of both power suppliers and consumers. In order to ensure the accuracy and safety of the electric energy meter during operation without human interference, at present, the practice of the electric power department is to install a plastic seal on the electric energy meter box to replace the traditional old lead seal. The plastic seal is made of engineering plastics. , which is mainly composed of a plastic sealing body inserted into the electric energy meter box casing, and a plastic sealing head exposed to the outside of the electric energy meter casing. The inside of the bolt caps of the ...
