[0036] During the process of fire fighting operations, lighting is usually required to provide illumination in smoky and dark places. In addition, the shock absorption and buffering protection functions of the helmets worn by firefighters are relatively single, unable to be applied to the heads of firefighters, affecting the wearing comfort, stability, and safety, and further affecting the protection effect during fire fighting operations. In this application, the head circumference fastening band 13 can be disassembled and adjusted according to the head circumference size of the wearer; the main function of the top head cover 2 is to fit on the top of the wearer's head, producing a buffering effect and increasing safety; the top head fastening band 3 is detachably connected to the top head cover 2, and the wearing depth can be adjusted according to the head size of the wearer, improving the wearing comfort and stability. Overall, this application can effectively improve the wearing comfort, stability, and safety by flexibly adjusting the wearing size of the helmet, and increase the protection effect during fire fighting operations.

[0037] A further optimized solution also includes:

[0038] A clamping block 14, the clamping block 14 is fixedly connected to the top head cover 2, and the first end of the head circumference fastening band 13 passes through the clamping block 14 and is clamped therein.

[0039] A number of second limiting holes are provided on the first end of the head circumference fastening band 13. When the first end of the head circumference fastening band 13 passes through the clamping block 14, the clip on the clamping block 14 is clamped in one of the second limiting holes according to its own elasticity, thereby realizing the installation of the head circumference fastening band 13 and the top head cover 2; when it is necessary to adjust the penetration length of the head circumference fastening band 13, directly press the clip located in the second limiting hole to make the clip disengage from the head circumference fastening band 13. At this time, move the head circumference fastening band 13. After releasing the clip, it will automatically rebound to the designated second limiting hole, and then the adjustment of the head wearing size is completed.
