Buckle type seal of electric energy meter

Abstract

The invention belongs to the technical field of seals, and in particular relates to a buckle type seal of an electric energy meter. The seal comprises a bolt and a seal cover, wherein the head of the bolt is placed in the seal cover; a bolt groove is arranged on the peripheral surface of a bolt head; an elastic prominence is arranged along the circumferential direction of the inner wall of the seal cover; the upper end part of the elastic prominence is inclined inwards the seal cover and leans against inside the bolt groove arranged at the bolt head, namely sealing is finished. According to the buckle type seal of the electric energy meter, a sealing twine does not need, alignment match to each seal hole is unnecessary and the requirement of the automatic sealing of a production line is completely met; and meanwhile, the buckle type seal of the electric energy meter is long in service life, convenient to mount and firm to fix; on the precondition of not damaging the seal of the electric energy meter, stealing electricity to the electric energy meter cannot be performed, so the buckle type seal of the electric energy meter has the advantages of anti-theft property, anti-falsification property and electricity stealing prevention property.

Description

technical field [0001] The invention belongs to the technical field of seals, in particular to a buckle-type seal for an electric energy meter. Background technique [0002] The energy meter seal is a device to prevent unauthorized people from opening the energy meter, which can prevent unauthorized people from changing the structure or setting of the energy meter to steal electricity. At present, in the power industry, the traditional sealing structure is to use the sealing line to pass through the plastic shell, seal the screw, and then insert the two ends into a sealing structure, and fix the sealing line by pressing or rotating, without damaging the sealing structure and Under the premise of breaking the sealing line, the sealing line cannot be pulled out, so that the sealing screw cannot be rotated, so that unauthorized people cannot unscrew the sealing screw, open the sealed structure, and play the role of sealing, anti-damage and anti-electricity theft. This structur...

AI Technical Summary

Problems solved by technology

This structure mainly has the following four deficiencies: first, the traditional seal needs to wear the seal line, the installation steps are cumbersome, and the sealing efficiency is low; second, the anti-theft performance of the traditional seal structure is poor; third, the lead used in the traditional seal, Serious environmental pollution, and long-term exposure to lead by installation staff, can easily cause poisoning; Fourth, traditional seals are not conducive to digital management and the need for efficient and automatic sealing

[0003] Although the existing technology has made many improvements to the seal structure, some of which do not need to wear the seal line, the installation steps have been simplified, but because the structure is still relatively complicated, and the correction between the seal hole and other parts is required, the installation operation It is cumbersome and cannot be automatically sealed; some improvements in the structure of the seal can temporarily prevent theft, but due to structural defects, the seal is relatively easy to age. After a period of time, the seal will reduce or lose the anti-theft performance. Frequent replacement is required, which increases management costs and is not conducive to implementation
