But the leaving of the keyhole still has certain hidden trouble.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that an electronic lock with a keyhole in the prior art has risks, and provides an anti-theft lock structure.

In order to realize above-mentioned purpose, design an anti-theft lock structure, including the lock core, the inside and outside both ends of lock core all be equipped with the key hole, its characterized in that: the anti-theft structure is arranged on the outer sides of the key holes at the inner end and the outer end of the lock cylinder, the anti-theft structure comprises an unlocking knob and a shifting piece, a channel is formed in the unlocking knob, a spring is arranged in the channel of the unlocking knob, one end of the shifting piece abuts against the spring, the other end of the shifting piece is inserted into the key hole, and the unlocking knob and the shifting piece can rotate along with the lock cylinder.

Preferably, the passageway in the unlocking knob is blind.

Preferably, the lock further comprises a coded lock disc, and the coded lock disc controls the lock cylinder to rotate through a wireless control device.

Compared with the prior art, the utility model has the advantages that:

1. the internal and external anti-theft structures can completely shield the key hole on the lock cylinder, so that the anti-theft risk brought by the key hole is avoided;

2. whether the lock cylinder idles or not can be controlled through a coded lock disc, mobile phone remote control, fingerprint card swiping and the like, so that unlocking and locking are realized;

3. when not unblanking, the knob of unblanking is in idle running state, can prevent effectively that violently from rotating the knob of unblanking destructively and unblank.

Detailed Description

The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 3 and 4, the utility model provides an anti-theft lock structure, which comprises a lock core, wherein both the inner end and the outer end of the lock core are provided with key holes, and the anti-theft lock structure is characterized in that: the anti-theft structure is arranged on the outer sides of the key holes at the inner end and the outer end of the lock cylinder, the anti-theft structure comprises an unlocking knob and a shifting piece, a channel is formed in the unlocking knob, a spring is arranged in the channel of the unlocking knob, one end of the shifting piece abuts against the spring, the other end of the shifting piece is inserted into the key hole, and the unlocking knob and the shifting piece can rotate along with the lock cylinder.

Referring to fig. 5 and 6, in a preferred embodiment, a combination lock disk is further included, which controls the rotation of the lock cylinder via a wireless control device.

The anti-theft lock structure is suitable for an electronic lock core structure with a key hole, as shown in figures 1 and 2, the lock core comprises a first rotor, a first linkage rotor, a second linkage rotor, a motor and a sliding block, one end of the first linkage rotor is provided with the key hole, the other end of the first linkage rotor is connected with the first rotor, one end of the second linkage rotor is provided with the key hole, the other end of the second linkage rotor is connected with the second rotor, and the first rotor and the second rotor are connected in a matched mode. The motor controls the sliding block to drive the first rotor to move, so that the first rotor and the second rotor are disconnected. When the first rotor is connected with the second rotor, the second linkage rotor can be rotated by a key to realize unlocking. When the first rotor is disconnected with the second rotor, the second linkage rotor can only idle and cannot be unlocked through a key.

The anti-theft structure is arranged outside the first linkage rotor and the second linkage rotor of the lock cylinder structure, a non-through channel is arranged inside the anti-theft structure shell, a spring is arranged in the channel, one end of a shifting piece is inserted into the key hole, and the other end of the shifting piece is abutted against the spring. The anti-theft structure completely shields the keyhole, so that the risk of theft is reduced. When the first rotor is connected with the second rotor, whether the lock cylinder idles or not can be controlled through a coded lock disc, mobile phone remote control, fingerprint card swiping and the like, so that unlocking and locking are realized.

Referring to fig. 5 and 6, the working principle of the utility model for adapting the electronic lock cylinder structure is as follows:

1. the unlocking principle is as follows: the lock is opened and closed by pressing a remote controller outside a door, or a mobile phone or an outdoor wireless transmission control box transmits a wireless unlocking signal, the indoor wireless receiving control box receives the signal, outputs unlocking voltage, and energizes a lock cylinder motor, so that the lock cylinder part outside the door does not idle, a lock knob is manually unscrewed to rotate, a shifting piece is driven to rotate, and the shifting piece drives the lock cylinder outside the door to rotate, thereby realizing unlocking.

2. And (3) locking principle: after the indoor wireless receiving control box outputs the unlocking voltage, the time is delayed for a moment, and then the locking voltage is output, so that the part outside the lock cylinder door is in idle rotation, and the lock cylinder cannot be driven to unlock due to the rotation of the poking piece because the part outside the lock cylinder is in idle rotation.
