Description

Technical Field

[0001] The present invention belongs to the field of anti-theft for computer big data devices with an alarm function, and specifically relates to an anti-theft cabinet for computer big data devices with an alarm function. Background Art

[0002] Big data, or massive data, refers to data volumes so large that they cannot be captured, managed, processed, and organized into information that helps enterprises make more proactive business decisions within a reasonable time through mainstream software tools. Since big data is crucial for enterprises, big data devices have become the targets of theft for many people.

[0003] The current big data anti-theft cabinets have the following disadvantages:

[0004] 1. Thieves have many unlocking tools, and ordinary door locks are easily opened by thieves. For some door locks with face recognition functions, thieves can also crack them through pictures or videos.

[0005] 2. When big data devices are stolen, the anti-theft cabinet cannot alarm in time, making it difficult for staff to discover in the first place and track the big data devices. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, to solve the problem that thieves have many unlocking tools and ordinary door locks are easily opened by thieves, and for some intelligent door locks, such as those with face recognition functions, thieves can also crack them through pictures or videos, and when big data devices are stolen, the anti-theft cabinet cannot alarm in time, making it difficult for staff to discover in the first place and track the big data devices.

[0051] The specific working process is as follows:

[0052] The big data device is fixed on the fixing device 20. Through the pulling force of the tension spring 2006, one end of the pressing plate 2001 can be tilted downward, so as to press down on the big data device to fix it. By inputting the correct password through the control panel 1002, the electric telescopic rod 1011 can be started. The electric telescopic rod 1011 drives the first rack 1010 to move. The movement of the first rack 1010 drives the first gear 1008 to rotate. The rotation of the first gear 1008 drives the second connecting rod 1009 to swing. The swing of the second connecting rod 1009 drives the door panel 1001 to swing, so that the door panel 1001 is opened. Since one end of the first connecting rod 1007 is fixedly connected with the fourth connecting rod 1013, the fourth connecting rod 1013 will swing along with the first connecting rod 1007. The swing of the fourth connecting rod 1013 will drive the fixed platform to swing. The swing of the fixed platform can drive the panoramic camera 1003 to swing, so that the panoramic camera 1003 protrudes from the cabinet body 1004, so as to obtain a larger field of view. Then, the person opening the cabinet is photographed and identified 360 degrees, and the person opening the cabinet is required to make corresponding actions according to the facial movements prompted by the voice. If the identification fails, the panoramic camera 1003 will send a signal to the control panel 1002, and the control panel 1002 will call the speaker 1006 to give an alarm. If the person opening the cabinet does not cooperate with the identification and takes the big data device, when the big data storage device is taken away, the convex block at the end of the pressing plate 2001 away from the big data device will contact the limit switch 2002, so as to trigger the limit switch 2002. The limit switch 2002 sends a signal to the control panel 1002, and the control panel 1002 starts the speaker 1006 to give an alarm. By starting the drive motor 3012, the rotation of the drive motor 3012 can drive one of the third gears 3002 to rotate. The rotation of the third gear 3002 can drive the fourth synchronous pulley 3009 to rotate. The rotation of the fourth synchronous pulley 3009 can drive the third synchronous pulley 3007 to rotate. The rotation of the third synchronous pulley 3007 can drive the fourth gear 3005 to rotate through the second synchronous belt 3010. The rotation of the fourth gear 3005 can drive the fifth gear 3006 to rotate in the reverse direction. The reverse rotation of the fifth gear 3006 can drive the second synchronous pulley 3004 to rotate in the reverse direction. The reverse rotation of the second synchronous pulley 3004 can drive the first synchronous pulley 3003 to rotate in the reverse direction through the first synchronous belt 3008, so that the first synchronous pulley 3003 drives the other third gear 3002 to rotate in the reverse direction, so that the third gears 3002 on both sides of the third layer plate 3001 can rotate actively, making the power more balanced. Since the third gear 3002 meshes with the second rack 3013, and the second rack 3013 is fixedly connected with the cabinet body 1004, the third gear 3002 can linearly move on the second rack 3013, so that the third gear 3002 moves the layer plate 3001 linearly, so as to adjust the height between the layer plates 3001.
