Description

Technical Field

[0001] The utility model is an explosion-proof sound and light alarm system for bank security, belonging to the field of sound and light alarm. Background Art

[0002] The sound and light alarm is also called the sound and light alarm. It is set up to meet the special requirements of customers for the alarm volume and installation location. It sends out two kinds of alarm signals, sound and light. It can be used in dangerous places to send warning signals to people through sound and various lights.

[0003] Banks are financial institutions established in accordance with the law to conduct monetary and credit business. They are the product of the commodity-money economy that has developed to a certain stage. Therefore, bank security is of vital importance. Now banks usually have access control systems installed to ensure that non-bank staff can only handle business in the business hall to prevent non-bank staff from entering the bank. However, some special locations in banks now usually only have explosion-proof sound and light alarms installed. If someone sneaks in and the security in the monitoring room does not notice it, data is likely to be lost, resulting in greater losses, which is quite troublesome. Utility Model Content

Among the two groups of sound and light alarms, the right explosion-proof sound and light alarm 2 is delayed by one second, and the left explosion-proof sound and light alarm 1 is delayed by two seconds. The tone of the left explosion-proof sound and light alarm 1 is adjusted lower than that of the right explosion-proof sound and light alarm 2, and the tone of the right explosion-proof sound and light alarm 2 is adjusted lower than that of the alarm bell 5, so that the tone of the alarm bell 5 is the highest. Therefore, when the alarm sounds, the alarm bell 5 sounds first and has the highest tone, and then the others sound in sequence. At this time, the right explosion-proof sound and light alarm 2 and the left explosion-proof sound and light alarm 1 sound from high to low, clearly and powerfully. The three sounds are mixed together, which can play a strong warning role. It is first started by detecting the light curtain 4. When the light source of the photoelectric sensor 41 is blocked by an object, an electrical signal will be sent out. At this time, the left explosion-proof sound and light alarm 1, the right explosion-proof sound and light alarm 2 and the alarm bell 5 will be triggered. The three will sound in turn. The sound is clear and powerful, which can attract people's attention and make a quick response. At the same time, a signal will be sent to the control room , the control room rings the bell to alert the security personnel, so that they can quickly go out. On the other hand, if the control room sees the thief from the monitoring for the first time, it can manually send a signal to the left explosion-proof sound and light alarm 1, the right explosion-proof sound and light alarm 2 and the alarm 5 to warn, and then notify the security or call the police; on the other hand, the sliding adjustment block 61 can be slid inward, which will drive the connecting rod 621 and squeeze the reset spring 63 to move inward. At this time, the limit block 6211 will retract into the housing of the embedded block 62, and then insert it, and then release the sliding adjustment block 61, At this time, the reset spring 63 drives the connecting rod 621 to reset, and the limit block 6211 extends out and inserts into the notch on the outside of the limit groove 32 for limiting, thereby limiting the position of the detection light curtain 4. Conversely, the sliding adjustment block 61 slides inward, which will drive the connecting rod 621 and squeeze the reset spring 63 to move inward. At this time, the limit block 6211 will retract into the shell of the embedded block 62 and then the detection light curtain 4 can be pulled out and removed. It is simple and convenient, and it is easy to disassemble the detection light curtain 4 for cleaning to prevent the detection light curtain 4 from being blocked by dust and the like and affecting its sensitivity.
