Anti-theft lock

Abstract

The invention discloses an anti-theft lock. The anti-theft lock comprises a locking plate, a lock frame, a lock plunger, an upper locking clamp, a lower locking clamp, an upper reset spring, a lower reset spring, a lock sleeve and a lock rod magnetic valve device, wherein the lock rod magnetic valve device is controlled by an indoor electric control device or an outdoor fingerprint identifier or an outdoor scrambler to work, the lock rod magnetic valve device is provided with a lock rod, the lock sleeve is arranged on the lock frame, the lock plate is matched in the lock sleeve in a sliding mode, and a return spring is arranged between the lock plate and the lock sleeve. The lock plate is provided with a top rod matched with the lock plunger, the lock plate is further provided with a catch matched with the lock rod, the upper locking clamp and the lower locking clamp are both hinged to the lock frame, and a lock plunger groove matched with the lock plunger is formed between the upper locking clamp and the lower locking clamp. One end of the upper locking clamp is connected with one end of the upper reset spring, the other end of the upper reset spring is connected to the lock frame, the lower locking clamped is connected with one end of the lower reset spring, and the other end of the lower reset spring is connected to the lock frame. The anti-theft lock is simple in structure, can be used for opening and closing a door without a key, and is good in anti-theft effect.

Description

Technical field [0001] The invention relates to an anti-theft lock, belonging to the technical field of locks. Background technique [0002] At present, locks are the basic equipment for people to protect property safety. Take the locks installed on residential gates as an example. The types of locks can be divided into manual and induction types. The so-called manual type is the rotation of the lock core on the key to open the door. Retract the latch to enter the room. In order to improve its anti-theft function, the structure of this kind of manual lock is becoming more and more complicated. There are two-stage or even three-stage. However, as long as there is a key hole for the key to be inserted, a skilled thief can insert a foreign object to open it. The anti-theft effect is not good. In the so-called induction type, an induction host is set on the door and opened with an induction card. The matching type of the induction host and the induction card is roughly divided into...

In order to improve its anti-theft function, the structure of this kind of manual lock is becoming more and more complicated. There are two-stage or even three-stage types. Anti-theft effect is not good

The so-called inductive type is to install an inductive host on the door, and then use an inductive card to open it. The cooperation between the inductive host and the inductive card can be roughly divided into two types: contact type and non-contact type. No matter what kind of inductive host, because They all use the chip to read the value of the proximity card to open the door. However, skilled thieves have a way to crack the value of the proximity card to open the door, and the anti-theft effect is not good.
