Anti-theft installation box for electric energy meter

Abstract

The invention relates to the technical field of electric energy meter mounting boxes and particularly relates to an electric energy meter anti-theft installation box. The installation box comprises a box body, wherein a threading opening is formed in a bottom plate of the box body, a wire protection pipe is arranged on the outer side of a bottom opening of the threading opening and fixed to the bottom face of the box body, a winding and unwinding groove is formed in the inner wall of the wire protection pipe, and an installation groove is formed in the surface of the winding and unwinding groove; a spring is arranged on a surface of the installation groove and arranged on the outer side of a limiting column in a sleeving mode, the limiting column is inserted into a through hole, the through hole is formed in the surface of the mounting groove, and the spring and the limiting column are both fixed to the surface of the clamping plate. The electric energy meter anti-theft installation box is advantaged in that the wire protection pipe is additionally arranged on the outer side of the wire penetrating opening, the push plate inserted into the surface of the wire protection pipe pushes the clamping plate to clamp the cable, and therefore when the cable is pulled out of the cable by mistake, the connecting position of the cable and the electric energy meter is not prone to loosening and falling, an elastic traction assembly is additionally arranged between the clamping plate and the winding and unwinding groove, and after the sleeve is detached, the clamping plate is pulled by the elastic traction piece and stored in the storage groove.

Description

technical field [0001] The invention relates to the technical field of an electric energy meter installation box, in particular to an anti-theft installation box for an electric energy meter. Background technique [0002] The electric energy meter is a tool for measuring the amount of electricity used by electrical appliances. Now we have used electric energy meters in large quantities in our lives, but some electric energy meters have this defect in their own structure, and it is very easy to pull wires privately without anyone monitoring them. Stealing electricity is easy to cause safety accidents, and the internal parts of some electric energy meters are more precise and easy to be stolen; for this reason, when installing electric energy meters, electric energy meters need to be installed in anti-theft installation boxes. [0003] In the prior art, the bottom plate of the anti-theft installation box of the electric energy meter is provided with a threading hole for the ca...

[0002] The electric energy meter is a tool for measuring the amount of electricity used by electrical appliances. Now we have used electric energy meters in large quantities in our lives, but some electric energy meters have this defect in their own structure, and it is very easy to pull wires privately without anyone monitoring them. The use of stolen electricity is prone to safety accidents, and the internal parts of some electric energy meters are more precise and easy to be stolen; for this reason, when installing the electric energy meter, the electric energy meter needs to be installed in the anti-theft installation box

[0003] In the prior art, the bottom plate of the anti-theft installation box of the electric energy meter is provided with a threading hole for the cable to pass through and be connected to the electric energy meter. However, when the cable is pulled from the bottom, the connection between the cable and the electric energy meter is likely to be loose; and the anti-theft A large amount of dust is easy to enter the threading opening of the installation box; for this reason, the present invention proposes an anti-theft installation box for electric energy meters to solve the above problems
