Description

Technical Field

[0001] The utility model relates to the technical fields related to display cabinets, exhibition halls and exhibition decorations, and in particular to an electronic lock for a display cabinet. Background Art

[0002] In exhibition halls, showcases are usually used to display exhibits. Existing showcases are usually made of glass. The glass cabinet doors are opened and closed by mechanical locks, so that it is convenient for staff to replace exhibits. However, mechanical locks are not only unsightly, but also do not have a good anti-theft function. For example, in the patent number "CN206174670U" and the patent name "Electronic lock and showcase", when the operator turns off the switch, the solenoid valve is powered off, and the telescopic rod moves away from the valve seat of the solenoid valve through the through hole, that is, the telescopic rod moves upward, and the telescopic rod drives the lock tongue to move upward and enter the keyhole, so that the electronic lock is in a closed state. At this time, the connecting rod is driven by the telescopic rod. The left end of the rod moves upward, so that the right end of the connecting rod moves downward, and the right end of the connecting rod moves downward, which drives the pull rod to move downward; when the operator turns on the switch, the solenoid valve is energized, the telescopic rod moves downward, and the telescopic rod drives the lock tongue to move downward and disengage from the keyhole, so that the electronic lock is in an open state. At this time, the left end of the connecting rod moves downward under the drive of the telescopic rod, so that the right end of the connecting rod moves upward, and the upward movement of the pull rod stretches the elastic element. When the solenoid valve is automatically powered off, the elastic element returns to its position, which will give the lock tongue an upward force, causing the lock tongue to move upward. However, the above electronic lock still has the following problems in actual use:

[0003] When valuable exhibits are placed in the display cabinet, when a thief pries the electronic lock, the electronic lock cannot promptly remind the security personnel, so that it cannot well protect the valuable exhibits, thereby causing certain losses to people's property safety.

[0004] Therefore, we proposed that electronic locks for display cabinets can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide an electronic lock for a display cabinet, so as to solve the problem in the current market proposed by the above background technology that when valuable exhibits are placed in the display cabinet, when a thief pries the electronic lock, the electronic lock cannot promptly remind the security personnel, so that it cannot play a good role in protecting the valuable exhibits, thereby causing certain losses to people's property safety.

[0011] The above structural arrangement enables the first sprocket to drive the second sprocket to rotate via the chain.

[0012] Preferably, a threaded rod is fixedly connected to the middle of the second sprocket, and the upper and lower ends of the threaded rod are connected to the electronic lock body bearing.

[0013] Through the above structural arrangement, the second sprocket can drive the right threaded rod to rotate together.

[0014] Preferably, the outer side surface of the threaded rod is threadedly connected to a connecting slider, and the connecting slider is in an "L" shape, and a protective plate is fixedly connected to the front side of the connecting slider, and a sliding connection structure is formed between the connecting slider and the electronic lock body.

[0015] Through the above-mentioned structural arrangement, the connecting slider can drive the protective plate to move up and down together.

[0016] Preferably, an infrared transmitter is disposed inside the electronic lock body, and the infrared transmitter is connected to the button and the fingerprint recognition element through a receiving line.

[0017] Through the above structural setting, when the password is entered incorrectly or the fingerprint does not match, the signal can be transmitted to the infrared transmitter.

[0018] Preferably, a buzzer alarm is fixedly mounted on the right side of the electronic lock body, and the left side of the buzzer alarm is connected to an infrared signal receiver.

[0019] The above-mentioned structural arrangement enables the buzzer alarm to receive the signal of the infrared transmitter through the infrared signal receiver.
