Electromagnetic protector with double-protection function

Abstract

The invention provides an electromagnetic protector with a double-protection function. The electromagnetic protector comprises a lock body and an external lock remover, wherein the lock body is arranged in a protected box body, and an electromagnetic coil and an electromagnet thimble are arranged in the protected box body; the lock body comprises at least two metal jacks; the lock remover comprises two layers of insulating strips, metal contact pins, springs, a power supply lead and a power supply connector; and an external power supply is a 24-36V alternating current power supply. The electromagnetic protector with the double-protection function has the advantages and positive effects that not less than three metal contact pins and metal plugholes as well as the electromagnetic coil and the electromagnet thimble are additionally arranged on the protector to ensure that the protected box body can be opened only under the action of both electromagnetic power and electric power, and the special selection of the 24-36V alternating current power supply ensures that the difficulty for opening the protected box body is greatly increased, so that the electromagnetic protector is safe, reliable, convenient and practical, and a stealer holding a conventional magnetic lock remover can do nothing but nail biting.

Description

technical field [0001] The invention relates to a lockset, in particular to an electromagnetic protection device with double protection functions. Background technique [0002] In traditional commodity sales, commodities with high value and which cannot be directly bound with hard plastic anti-theft buckles are placed in a solid non-metallic box, which is equipped with a magnetic anti-theft device with a locking function. The device relies on an external magnetic unlocker to suck the buckle open so that the box body can be opened and the items in the box can be taken out. [0003] This lock buckle comprises shell, lock core, and spring and thimble are housed in the lock core. Under normal conditions, the spring pushes the end of the thimble out of the lock cylinder into the lock hole of the box body to lock the box body where the product is placed. When opening the box body, use the external magnetic unlocker to suck all the thimbles into the lock cylinder. In addition, t...
