CN204409716U - A kind of safety cap that workman can be reminded correctly to wear - Google Patents

Abstract

The utility model aims at the phenomenon that many construction site workers directly wear the safety helmet on the head without buckling the buckle belt for comfort or convenience when working, and discloses a safety helmet that can remind the workers to wear it correctly. Effectively remind workers to wear the helmet correctly and buckle the buckle of the helmet. It includes an infrared remote control, a pressure sensitive sensor, a battery, a microprocessor, a buzzer, and an infrared receiving device. When the infrared remote control sends a signal to the infrared receiving device, the infrared receiving device transmits the signal to the microprocessor after receiving the signal. signal, the microprocessor will control the buzzer to work, when the pressure-sensitive sensor is under pressure, it will send a signal to the microprocessor, and the microprocessor will stop the buzzer after receiving the signal from the pressure-sensitive sensor Work, when the pressure sensitive sensor is no longer under pressure, the microprocessor will control the buzzer to buzz again.

Description

A hard hat that reminds workers to wear it correctly

technical field

The utility model relates to a safety helmet, more specifically, relates to a safety helmet which can remind workers to wear it correctly.

Background technique

Workers often need to wear safety helmets when working on the construction site or performing high-altitude operations, but many workers directly wear the safety helmets on their heads without buckling the buckle belt for comfort or convenience. In this way, the safety helmets are easy to fall off during work. , not only fails to protect the workers, but also may cause the safety helmet to fall and hit people or objects, causing huge injuries. Therefore, there is a need in the market for a safety helmet that can remind workers to wear it correctly.

Contents of the invention

The purpose of this utility model is to provide a safety helmet, which can effectively remind workers to wear the safety helmet correctly and buckle the buckle of the safety helmet.

A safety helmet capable of reminding workers to wear it correctly according to the utility model includes a safety helmet, a reminder circuit, and an infrared remote controller. Composed of a female head, the reminder circuit includes a pressure-sensitive sensor, a battery, a microprocessor, a buzzer, and an infrared receiving device. The pressure-sensitive sensor is placed on the inner wall of the female head, and the battery is a lithium battery. The above-mentioned battery, microprocessor and buzzer are placed inside the helmet, and the infrared receiving device is installed on the shell of the helmet. When the infrared remote controller sends a signal to the infrared receiving device, the infrared receiving device receives the signal. After the signal, the signal is transmitted to the microprocessor. After the microprocessor receives the signal from the infrared receiving device, it will control the buzzer to work, and the buzzer will buzz immediately. When the pressure sensitive sensor After being under pressure, it will send a signal to the microprocessor, and after the microprocessor receives the signal from the pressure-sensitive sensor, it will stop the buzzer from working, and the buzzer will not buzz immediately. After the sensitive sensor is no longer under pressure, the microprocessor will re-control the buzzer to buzz, and the safety helmet is made of hard plastic.

In this way, when the workers enter the construction site, the supervisors on the construction site will control the buzzer in the safety helmet worn by the workers to make a buzzing sound through the infrared remote control. belt, the pressure-sensitive sensor in the female head will be stressed, and the microprocessor will control the buzzer so that it does not work. Since the buzzer is installed in the helmet, when the buzzer is working, it will make a buzzing sound, and the workers wearing the helmet will feel very uncomfortable. Only when the buckle is fastened correctly, the buzzer will not work , so that the workers are forced to fasten the buckle when wearing the helmet, thus effectively protecting the safety of the workers. The utility model has the advantages of simple structure, convenient use, low cost and convenient mass production.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

A helmet of the utility model that can remind workers to wear it correctly includes a helmet 1, a reminder circuit 2, an infrared remote controller 3, and a buckle 5 is installed on the shell of the helmet 1, and the buckle 5 is provided by a public The head 6 and the female head 7 are composed, and the reminder circuit 2 includes a pressure-sensitive sensor 8, a battery 9, a microprocessor 10, a buzzer 11, an infrared receiving device 12, and the pressure-sensitive sensor 8 is placed on the female head 7 On the inner wall, the battery 9 is a lithium battery, the battery 9, the microprocessor 10 and the buzzer 11 are placed inside the helmet 1, and the infrared receiving device 12 is installed on the shell of the helmet 1, when Described infrared remote controller 3 sends signal to infrared receiving device 12, and after infrared receiving device 12 receives this signal, just passes to microprocessor 10, after microprocessor 10 receives the signal that sends from infrared receiving device 12, The buzzer 11 will be controlled to work, and the buzzer 11 will buzz immediately. When the pressure-sensitive sensor 8 is pressed, it will send a signal to the microprocessor 10, and the microprocessor 10 will receive the signal. After the signal from the pressure-sensitive sensor 8, the buzzer 11 will stop working, and the buzzer 11 will not buzz immediately. After the pressure-sensitive sensor 8 is no longer under pressure, the microprocessor 10 will re-control. The buzzer 11 buzzes.
