Description

Technical Field

[0001] The utility model relates to the technical field of lock bodies, in particular to an electric plug lock with an anti-fraud lock function. Background Art

[0002] With the popularization and rapid development of new retail and intelligent vending, refrigerators and display cabinets are commonly used for displaying, storing and selling goods. Due to the selling attribute, electric plug locks are commonly used as the main anti-theft means for refrigerators and display cabinets. Most of the electric plug locks on the market use magnetic sensitive elements to detect the magnets for positioning on the door body as the "door magnetic" signal to determine whether the cabinet door is properly closed. However, since magnets are readily available in daily life, it is very easy for people with ulterior motives to take advantage of this loophole, making the electric plug lock mistakenly think that the door is closed and perform the locking operation, resulting in the behavior of "fraudulent locking". Content of the Utility Model

[0003] In order to overcome the defects existing in the prior art, the utility model provides an electric plug lock with an anti-fraud lock function to solve the problem that the existing electric plug locks are easily fraudulently locked by people with ulterior motives.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an electric plug lock with an anti-fraud lock function, including a lock body, a lock piece and a controller. The lock body includes a lock tongue, and the lock tongue faces an insertion hole opened on the lock piece.

[0005] The lock piece is further provided with a magnet matrix, and the lock body further includes a detection element. The detection element is electrically connected to the controller. The detection element is used to obtain the magnetic pole attribute and magnetic field strength of the magnet matrix, and the controller is used to determine whether the locking is successful based on the magnetic pole attribute and magnetic field strength.

[0006] Preferably, the lock body is arranged on the cabinet body and the lock piece is arranged on the cabinet door, or the lock body is arranged on the cabinet door and the lock piece is arranged on the cabinet body; when the cabinet door is closed, the lock tongue faces the insertion hole, and the detection element faces the magnet matrix.

[0007] Specifically, the detection element is a Hall element.

[0008] Optionally, the magnet matrix is composed of a plurality of magnets arranged.

[0009] It is worth noting that the lock body further includes a solenoid valve and a transmission link. The solenoid valve is electrically connected to the controller, and the action output end of the solenoid valve is connected to the lock tongue through the transmission link.

[0010] Specifically, it further includes a lock housing, and the lock body is arranged inside the lock housing.

[0011] The beneficial effects of the present utility model are as follows: In the electric plug lock with anti-fraud lock function, different magnetic pole attributes and magnetic field intensities can be set according to needs. The set magnetic pole attributes and magnetic field intensities are pre-recorded in the controller. When the magnetic pole attributes and magnetic field intensities detected by the detection element correspond to the pre-set magnetic pole attributes and magnetic field intensities recorded in the controller, the lock tongue will insert into the insertion hole to achieve locking. Since the magnetic pole attributes and magnetic field intensities are set and can be changed before use, even if a person with ulterior motives uses a magnet to perform a "fraudulent lock" behavior, since the magnetic pole attributes and magnetic field intensities detected by the detection element cannot exactly match the preset values recorded in the controller, the controller will not consider the locking to be successful, thus achieving the purpose of anti-fraud lock.

[0016] The following further describes the specific embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] As Figures 1-3 shown, an electric plug lock with anti-fraud lock function includes a lock body 1, a lock piece 2 and a controller. The lock body 1 includes a lock tongue 11, and the lock tongue 11 faces an insertion hole 21 opened in the lock piece 2;

[0018] The lock piece 2 is further provided with a magnet matrix 22. The lock body 1 further includes a detection element 12. The detection element 12 is electrically connected to the controller. The detection element 12 is used to obtain the magnetic pole attributes and magnetic field intensities of the magnet matrix 22, and the controller is used to determine whether the locking is successful based on the magnetic pole attributes and magnetic field intensities.

[0019] In the electric plug lock with anti-fraud lock function, different magnetic pole properties and magnetic field intensities can be set as needed, and the set magnetic pole properties and magnetic field intensities are pre-recorded in the controller. When the magnetic pole properties and magnetic field intensities detected by the detection element 12 correspond to the preset magnetic pole properties and magnetic field intensities recorded in the controller, the lock tongue 11 will insert into the insertion hole 21 to achieve locking. Since the magnetic pole properties and magnetic field intensities are set before use and can be changed, even if a person with ulterior motives uses a magnet to perform a "lock fraud" behavior, since the magnetic pole properties and magnetic field intensities detected by the detection element 12 cannot exactly match the preset values recorded in the controller, the controller will not consider the lock closing successful, thus achieving the purpose of anti-fraud lock.

[0020] It should be noted that the lock body 1 is arranged on the cabinet body 4 and the lock piece 2 is arranged on the cabinet door 5, or the lock body 1 is arranged on the cabinet door 5 and the lock piece 2 is arranged on the cabinet body 4; when the cabinet door 5 is closed, the lock tongue 11 faces the insertion hole 21, and the detection element 12 faces the magnet matrix 22. When the cabinet door 5 rotates relative to the cabinet body 4, it can drive the lock piece 2 or the lock body 1 to move. When the cabinet door 5 is closed, since the detection element 12 faces the magnet matrix 22, the magnetic pole properties and magnetic field intensities of the magnet matrix 22 can be detected.

[0021] Preferably, the detection element 12 is a Hall element.

[0022] Specifically, the magnet matrix 22 is composed of multiple magnets arranged. The multiple magnets are arranged to form an array-structured magnet matrix 22. By setting different numbers of magnets, the magnetic field intensity of the magnet matrix 22 can be changed, and by setting the surface of the magnet facing the detection element 12, the setting of the magnetic pole properties can be achieved.

[0023] Optionally, the lock body 1 further includes a solenoid valve 13 and a transmission link 14. The solenoid valve 13 is electrically connected to the controller, and the action output end of the solenoid valve 13 is connected to the lock tongue 11 through the transmission link 14. When the magnetic pole properties and magnetic field intensities detected by the detection element 12 correspond to the preset magnetic pole properties and magnetic field intensities recorded in the controller, the controller sends an electrical signal to drive the action output end of the solenoid valve 13 to act. The action output end of the solenoid valve 13 drives the transmission link 14 to act, and the transmission link 14 drives the lock tongue 11 to act and insert into the insertion hole 21.

[0024] It should be noted that a lock shell 3 is further included, and the lock body 1 is arranged inside the lock shell 3. The lock shell 3 is used to protect the lock body 1 and has the function of dust and water protection.

[0025] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
