[0002] A flip-back structure helmet is a helmet with a special design, which features a helmet body that can flip backwards to provide a wider field of view when needed, or provide greater protection when not needed. This type of helmet is often used in military, security, racing and other occasions that require flexible vision and protection.

[0003] In the existing technology, firstly, some devices cannot provide additional protection for the neck in the event of an accident, increasing the risk of neck injury, and cannot adjust the protection range of the helmet according to different usage environments or personal preferences, which reduces the applicability of the helmet. The helmet can only provide basic head protection and lacks versatility. Secondly, some devices cannot adjust the tightness of the rear roll-over protection frame, which may cause the rear roll-over protection frame to be too loose or too tight, affecting the wearing comfort and safety. It is impossible to fine-tune according to the wearer's head size, reducing the fit and protective effect of the helmet. Finally, some devices may require more time and effort to adjust the helmet, which is not simple and quick enough. The size adjustment of the helmet may not be precise enough, affecting the wearing comfort and safety. The stability of the helmet after adjustment may be affected, requiring more frequent inspection and maintenance. Utility Model Content

When it is necessary to further adjust the size of the helmet, the rotating tube 12 drives the tightening block 14 and the deep groove hole 22 in the rotating groove 17 to lock step by step, and the tightening spring 15 provides adjustment force to make the movable rod 13 move laterally on the matching block 16, thereby adjusting the locking degree of the telescopic frame 9 in the slot 6.

[0035] The operator puts the helmet on his head and adjusts the position of the facial protection mirror 21 to ensure a clear field of vision. By rotating the adjustment mechanism and the auxiliary adjustment mechanism, the operator adjusts the rotation and locking degree of the rear-flip protective frame 5 in the helmet to ensure that the helmet fits comfortably on the head.
