Abstract

A double-ring electronic anti-theft lock includes: an iron chain having a first state and a second state; a slider lock rod set on the iron chain; a locking assembly set at one end of the iron chain; an iron ring set at the end of the iron chain away from the locking assembly. When the iron chain is in the first state, the locking assembly does not contact the slider lock rod, and the iron ring is not fitted on the iron chain. When the iron chain is in the second state, the locking assembly contacts the slider lock rod, and the iron ring is fitted on the iron chain. By passing the iron ring through the locking assembly and the slider lock rod and fitting it on the iron chain, the locking assembly is locked with the slider lock rod, thus forming the iron chain into a figure-8 shape.

Claims (31)

1 . A double-ring electronic anti-theft lock, comprising:

an iron chain, wherein the iron chain has a first state and a second state;

a slider lock rod, wherein the slider lock rod is set on the iron chain;

a locking assembly, wherein the locking assembly is set at a first end of the iron chain; and

an iron ring, wherein the iron ring is set at a second end of the iron chain, and the second end of the iron chain is away from the locking assembly;

wherein when the iron chain is in the first state, the locking assembly does not contact the slider lock rod, and the iron ring is not fitted on the iron chain; and

when the iron chain is in the second state, the locking assembly contacts the slider lock rod, and the iron ring is fitted on the iron chain,

wherein the locking assembly comprises:

a lock body, wherein the lock body is connected to the iron chain, and an electronic component is set on the lock body; when the iron chain is in the second state, the lock body locks with the slider lock rod, and the electronic component matches with the slider lock rod;

a rivet, wherein the rivet is set on the lock body, and the first end of the iron chain is connected to the lock body through the rivet; and

a rubber sleeve for the lock body, wherein the rubber sleeve is fitted on the lock body, wherein the rubber sleeve comprises:

an upper rubber sleeve, wherein the upper rubber sleeve is fitted on the lock body;

a lower rubber sleeve, wherein the lower rubber sleeve is fitted on the lock body, the lower rubber sleeve is located below the upper rubber sleeve, and the lower rubber sleeve has a through hole matching with the slider lock rod; and

a marking cover plate, wherein the marking cover plate is set between the upper rubber sleeve and the lower rubber sleeve, to fix the upper rubber sleeve relative to the lower rubber sleeve.

2 . The double-ring electronic anti-theft lock according to claim 1 , further comprising:

a fabric sleeve for the iron chain, wherein the fabric sleeve is set on the iron chain, and the slider lock rod is fitted on the fabric sleeve;

a fastening joint for the fabric sleeve, wherein the fastening joint is set on an end of the fabric sleeve near the locking assembly, and the iron chain passes through the fastening joint and is connected with the locking assembly; and

an additional joint, wherein the additional joint is set on an end of the fabric sleeve near the iron ring.

3 . The double-ring electronic anti-theft lock according to claim 1 , wherein

the lock body comprises:

a casing, wherein the casing has a recess matching with the electronic component;

a lock cylinder, wherein the lock cylinder is set on the casing, and the lock cylinder has a keyhole on top; and

a lock core, wherein the lock core is set inside the casing, the lock core is connected to the lock cylinder, the lock core moves with the lock cylinder, and the slider lock rod locks with the lock core.

4 . The double-ring electronic anti-theft lock according to claim 3 , wherein

the lock core has a semicircular groove of the lock core, and the slider lock rod has a semicircular groove of the lock rod matching with the semicircular groove of the lock core, wherein a key is inserted into the keyhole, and the lock core is turned clockwise by ninety degrees with the key to disengage the slider lock rod from between the semicircular groove of the lock core and the casing.

5 . The double-ring electronic anti-theft lock according to claim 3 , wherein

the slider lock rod is provided with a magnetic signal transmitting end, and the electronic component is provided with a magnetic signal receiving end; and when the slider lock rod is locked with the lock core, the magnetic signal transmitting end corresponds to the magnetic signal receiving end.

6 . The double-ring electronic anti-theft lock according to claim 3 , wherein

the casing has a recess for placing the electronic component, and the electronic component is fixed in the recess by screws; and when the lock core is locked with the slider lock rod, the screws face towards the slider lock rod.

7 . The double-ring electronic anti-theft lock according to claim 3 , wherein

the iron chain also has a third state; and when the iron chain is in the third state, the lock core is locked with the slider lock rod, and the iron ring is not fitted on the iron chain.
