Embodiment 1

[0032] Example 1, such as figure 1 , 2As shown in , 4 and 5, an anti-fouling locking seal includes a seal body 2 and a sealing line 3, the seal body 2 is provided with an RFID or two-dimensional code electronic label 8, the seal body 2 and the electronic label 8 The outside is wrapped with a layer of heat insulation layer 9 again. Heat insulating layer 9 can be selected high-density polyethylene for use, and thickness is not more than 0.5mm. The sealing wire 3 is composed of multiple strands of stainless steel wire, which has the characteristics of strong tensile strength, high flexibility, wear and bending resistance, high temperature resistance, and non-skid. Wrap the plastic layer outside the insulation layer. The plastic layer 1 can adopt PC polycarbonate or ABS resin. The plastic layer 1 is provided with an inlet 11 for passing through the sealing wire 3, and one end of the sealing wire 3 is fixed to the sealing body 2, and after being plastic-sealed by the plastic la...

Abstract

Provided is a tamper-resistant automatic warning device, comprising a seal body and a seal wire. The periphery of the seal body is wrapped with a transparent plastic layer. The plastic layer is provided with an inlet used for the seal wire to pass through. One end of the seal wire is fixed with the seal body, and through plastic sealing by the plastic layer, the seal wire goes through the plastic layer, and then comes back to enter the seal body through the inlet. The seal body comprises a housing. The housing is internally provided with a storage cavity. The storage cavity is internally provided with a rotation device which rotates freely, and a driving rod used to drive the rotation device to rotate and make the rotation device and the housing fixedly lock. The housing is internally provided with a warning device. The device can effectively deter occurrence of user electricity stealing, and can perform real-time monitoring, sealing-off changing and other operations on a sealed meter, so as to realize digitized and intelligent management.

Description

technical field [0001] The invention relates to a sealing device of metering equipment, especially the sealing of electric meter cabinets or water meters. Background technique [0002] Many places where existing seals are installed are exposed to the wind and rain. After using it for a period of time, it often happens that the seal is filled with mud. In recent years, various domestic scientific research institutes and production enterprises have developed various new types of seals to replace the traditional lead seals widely used in various sealing devices. With the gradual maturity of radio frequency identification (RFID) and two-dimensional barcode technology and its rapid promotion and application, the digital metering seal based on RFID and two-dimensional barcode technology has become a representative of new seals, and has been rapidly applied in industries such as electric power and water affairs. Combined with PDA and wireless communication technology, operations ...
