Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 2 to 4, in a first embodiment of the present invention, there is provided a knock-proof lock, including a lock body and a lock beam 10 locked with the lock body, further including:

the tail end of the rotor 20 is rotatably arranged on the driving mechanism, a bayonet 11 matched with the rotor 20 is concavely arranged on the lock beam 10, and the front end of the rotor 20 is inserted into the bayonet 11 during locking;

and the driving mechanism is arranged on the lock body, is in linkage connection with the rotor 20 and drives the rotor 20 to rotate.

The single-bolt lock in the prior art can be knocked open because the single-bolt is knocked on the back of the single bolt of the lock, so that the single bolt generates linear inertia force and moves towards the back, and the lock is illegally unlocked. Therefore, in this embodiment, the rotor 20 is inserted into or removed from the bayonet 11 of the lock beam 10 by rotation, and the rotor 20 is disposed on the driving mechanism, since the driving mechanism and the rotor 20 are difficult to move or rotate by the force applied to the electronic lock by the external knocking, the purpose of preventing illegal unlocking by the knocking can be achieved. Specifically, the tail end of the rotor 20 is rotatably arranged on a driving mechanism, a bayonet 11 matched with the rotor 20 is concavely arranged on the lock beam 10, and when the lock is locked, the driving mechanism controls the front end of the rotor 20 to be rotatably inserted into the bayonet 11; when the lock is unlocked, the driving mechanism controls the front end of the rotating piece 20 to rotate to be separated from the bayonet 11. The rotor 20 may be in the form of a block, but may be in the form of a cylinder.

Referring to fig. 2 to 4, in a second embodiment of the present invention, the driving mechanism is a motor 30, a transmission shaft 31 is disposed on the motor 30, and the rotor 20 is disposed on the transmission shaft 31 and rotates around the transmission shaft 31.

In this embodiment, the transmission shaft 31 is transmitted to the rotor plate 20 to rotate the rotor plate 20 by a predetermined angle. When the lock is unlocked, the rotating piece 20 is driven to rotate by a preset angle to be separated from the bayonet 11. When locking, the rotor 20 is driven to rotate a predetermined angle until the rotor 20 is inserted into the bayonet 11.

Referring to fig. 2 to 4, in a third embodiment of the present invention, a limit cam 40 is further disposed on the transmission shaft 31, and the limit cam 40 is disposed at the bottom of the rotor 20.

In this embodiment, the limit cam 40 is used to limit the position of the rotor 20, and can reduce the degree of wear of the rotor 20 when rotating on the motor 30.

Referring to fig. 2 to 4, in a fourth embodiment of the present invention, a torsion spring 50 is further disposed on the transmission shaft 31, a spiral section 51 at the middle of the torsion spring 50 is sleeved on the outer side of the transmission shaft 31, and a straight section 52 at the end of the torsion spring 50 is fixed to the rotor 20.

In this embodiment, the torsion spring 50 can further prevent the rotor plate 20 from rotating when being knocked, so as to achieve the safety purpose of preventing knocking-off.

In the fifth embodiment of the present invention, the present invention further comprises a control mechanism, and the control mechanism is in communication connection with the motor 30;

the control mechanism sends an unlocking instruction to the motor 30, the motor 30 rotates forwards to drive the rotary piece 20 to rotate to be separated from the bayonet 11;

the control mechanism sends a locking command to the motor 30, the motor 30 rotates reversely, and the rotor plate 20 is driven to rotate to be inserted into the bayonet 11.

In a fourth embodiment of the present invention, the lock further comprises a password input mechanism, which is disposed on the outer surface of the lock body, is in communication connection with the control mechanism, and sends a password command to the control mechanism;

the control mechanism receives the password command and compares the password command with a prestored comparison command, and if the password command is consistent with the prestored comparison command, an unlocking command is sent to the motor 30.

In this embodiment, the password input mechanism may be a number key or a fingerprint recognizer.

To sum up, the electronic lock for preventing knocking open of the utility model comprises a lock beam, a lock body, a rotor and a driving mechanism, wherein the rotor is rotatably arranged on the driving mechanism, and the front end of the rotor is inserted into the bayonet during locking; when the lock is unlocked, the driving mechanism drives the rotating piece to rotate to be separated from the bayonet. Because the driving mechanism and the rotor plate are difficult to move or rotate by the acting force applied to the electronic lock by knocking from the outside, the aim of preventing illegal unlocking by knocking is fulfilled. Therefore, the utility model discloses a prevent electronic lock that knocks open avoids the tool to lock to be illegally knocked open, improves the security of tool to lock, protection property safety.
