Multifunctional seal with lining device

Abstract

The invention relates to a multifunctional seal with a lining device, which comprises a base, an upper cover outer ring fixed on the base and a top cover. The top cover covers the upper end portion of the upper cover outer ring. A base lining and an upper cover lining are arranged on the upper cover outer ring. The base lining is a column body with a counter bore in the middle. The upper cover lining is a column-shaped sleeve, the bottom of the upper cover lining is fastened at the top end of the base lining, and the top portion of the upper cover lining abuts against the top cover. By means of support of the base lining, the upper cover lining can provide strong support capability. By means of the structure, when the top cover meets external violence impact, the top cover is not easy to break due to strong inner support. In actual use, a screw to be sealed penetrates through the counter bore of the base lining to be screwed on an electric meter casing to be sealed to fix the integral structure on the electric meter casing to be sealed. The multifunctional seal is firm in fixation and convenient to install.

Description

technical field [0001] The invention relates to a seal, in particular to a multifunctional seal with a lining device, which is suitable for single-phase electric energy meters, three-phase electric energy meters, and power terminal equipment requiring sealing. 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 stuff the two ends into a sealing structure, and use pressure or rotation to fix the sealing line, without damaging the sealing structure and The sealing line can be pulled out under the premise of breaking the sealing line, so that the sealing screw cannot be rotated. Unauthorized persons cannot unscrew the sealing screw an...

AI Technical Summary

Problems solved by technology

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 stuff the two ends into a sealing structure, and fix the sealing line by pressing or turning, without damaging the sealing structure and The sealing line can be pulled out under the premise of breaking the sealing line, so that the sealing screw cannot be rotated

Make it impossible for unauthorized persons to unscrew the sealing screw and open the sealed structure

This structure mainly has the following four deficiencies: First, the traditional seal needs to wear the seal line, press the seal or transfer the seal, and also need to align the holes when screwing.

Although this improved technology can replace the traditional seal, its protective structure is not strong enough, and it is easy to be damaged when resisting external violent impact. Its anti-theft performance is poor, especially easy to imitate, which is not conducive to digital management, and its anti-theft performance is poor.
