An anti-theft alarm device that can adopt two alarm modes of sound and light

Abstract

The invention discloses an anti-theft alarm device capable of adopting sound and light alarm modes, which comprises a locker, an exhibition stand, a spare power supply box and an audible and light alarm. A background board is installed on the back of the locker, and the background The board is a hollow structure. Three groups of sound and light alarms and camera lenses are installed on the front of the background board, and the camera lens is located below the sound and light alarms. The sound and light alarms are electrically connected to the camera lenses through wires. The second A spare power supply box is installed inside the cavity, and the inner bottom wall of the second cavity is provided with a heat dissipation frame, and the heat dissipation frame is located in front of the spare power supply box, and three sets of exhibition stands and labels are installed on the top surface of the locker board, and the front of the locker is provided with a door. The present invention is equipped with an audible and visual alarm, which can provide fence-type anti-theft protection for exhibits that need to be protected while the device performs an audible and visual alarm to deter thieves, increasing the difficulty of anti-theft of the device, thereby achieving double protection of alarm and anti-theft.

Description

technical field [0001] The invention relates to the technical field of anti-theft equipment, in particular to an anti-theft alarm equipment which can adopt sound and light alarm modes. Background technique [0002] The function of the alarm is not only to send a warning signal to the staff, but also to deter the thief, in the hope that he can stop the theft, so as to protect the goods from being stolen. Therefore, the use of the alarm has a more important role in preventing theft. In addition, with the continuous improvement of the alarm technology, the function of the alarm is no longer limited to the buzzer warning, the sound and light alarm sends out the buzzer warning and the light signal warning, and the two-pronged approach strengthens the warning of the alarm. The role has been strongly welcomed by the market. [0003] The defective that existing anti-theft device exists is: [0004] 1. Patent document CN105469517A discloses a light-emitting component and a light-em...

AI Technical Summary

Problems solved by technology

Alarms with the same output power double the number of loads and double the alarm time", but lack effective anti-theft protection. When the alarm cannot deter thieves after the alarm sends out sound and light alarm information, the anti-theft protection of the device is limited. ;

[0005] 2. Patent document CN110341525A discloses a two-way V2G charging pile anti-theft alarm device, "including an anti-theft alarm device and an alarm system. The anti-theft alarm device includes a V2G charging pile shell and a bottom mounting plate. The top of the bottom mounting plate is provided with a three-sided card slot. The bottom of the V2G charging pile shell is fixedly installed with a card plate, and the side wall of the V2G charging pile shell is fixedly installed with a cover plate. The card plate cooperates with the three-side card slots. The cavity is provided with a long inner slot, the top of the long inner slot is fixedly installed with the upper terminal, the bottom of the long inner slot is fixed with the lower terminal, the bottom of the cylindrical slot is fixed with a spring, and the top of the spring The long board is fixedly installed, and the top of the long board is fixedly installed with a cover tube. The invention can prevent people from stealing the cables and electronic components in the shell of the V2G charging pile, and the cost is low, and no one needs real-time monitoring, so it has a good market prospect ", but after the thief maliciously destroys the normal power supply of the device, the device loses the alarm function and cannot play the corresponding sound and light alarm function;

[0006] 3. Patent document CN104088505A discloses a net-type safety fence with infrared sound and light alarm function, "including the safety fence body; the safety fence body includes a four-way infrared detector, sound and light alarm, sound and light Alarm base, fixed pin, rotating fixed shaft, net hook fixed disc, rotating sleeve, net lower hook fixed disc, fence body base, drag net, drag net hook and drag net lower hook; through a safety fence An infrared transmitter of the body cooperates with an infrared receiver of another safety fence body to realize the infrared arming between the two safety fence bodies. When someone pulls across the two safety fence bodies When the network is connected, the sound and light alarm will send out a sound and light alarm, and the alarm signal will be uploaded to the background host; through the cooperation of the multiple mesh safety fences, the integrated deployment of safety fence pulling nets and infrared shooting in a certain area can be realized ", but it lacks the corresponding reminder function, and it is impossible to effectively distinguish some accidental collisions and accidental collisions from actual theft actions, which may easily cause information misjudgment
