Description

Technical Field

[0001] This utility model relates to the technical field of helmet wearing detection equipment, and in particular to a helmet wearing detection alarm mechanism. Background Technology

[0002] A safety helmet is a protective garment specifically designed to protect the head from specific injuries such as falling objects, collisions, and electric shocks. Through mechanisms such as cushioning and shock absorption and dispersing impact force, it minimizes the damage to the head caused by external forces.

[0003] Existing safety helmets generally only provide basic protection and cannot detect whether they are worn correctly. Workers may wear them incorrectly due to negligence or habit, causing the safety helmets to fail to function effectively in an accident. In addition, manual inspection by safety officers is required, which can lead to problems such as missed inspections and untimely inspections.

[0004] To address the problem that existing safety helmets cannot detect whether they are worn correctly, and that workers may wear them incorrectly due to negligence or habit, rendering the helmets ineffective in the event of an accident, this new safety helmet incorporates a wearing detection mechanism. This mechanism can detect whether the user is wearing the helmet correctly. When the helmet is not worn or is worn incorrectly, the helmet will issue an alarm to remind the user that the helmet is not being worn properly. Utility Model Content

[0005] To overcome the limitations of existing safety helmets, which generally only provide basic protection and cannot detect whether they are worn correctly, workers may wear them incorrectly due to negligence or habit, rendering the helmets ineffective in the event of an accident. In addition, manual inspection by safety officers is required, which can lead to problems such as missed inspections and untimely inspections.

An obstruction detector is installed via a mounting block to detect whether the helmet body is worn on the wearer's head. The helmet body is fixed on the wearer's head via a chin strap. Identification is performed via a contact switch. When the contact switch is open, the relay built into the contact switch changes from normally open to normally closed, triggering a voice alarm. If the contact switch is closed, the relay changes from normally closed to normally open, stopping the voice alarm.

[0008] As a preferred option, a protective brim is provided on one side of the main body of the safety helmet, a mounting platform is provided on the top surface of the protective brim, and a monitoring probe is provided on one side of the mounting platform.
