[0008] As preferred, the headlock hanging piece is inserted into the hanging piece pre-embedded part through the hook foot plug buckle structure and is fixed. The headlock hanging piece is connected and fixed through the plug-in structure, and the hook foot plug buckle structure at both ends of the headlock hanging piece is inserted into the slot structure of the hanging piece pre-embedded part and is fixed, then the wing is installed on the sliding groove of the headlock hanging piece, the headlock assembly is connected and assembled with the wing, and finally the fabric belt can be assembled.

[0009] As preferred, a plurality of fabric belt grooves are formed on the headlock hanging piece, and inclined grooves which are communicated with the fabric belt grooves are formed on the main body of the headlock hanging piece. When the fabric belt is assembled, the inclined grooves on both sides of the headlock hanging piece can be directly sleeved into the fabric belt grooves, so that the assembly is convenient and fast, and the fabric belt is not worried about falling off, and the fabric belt does not need to be threaded through each component.

[0010] As preferred, the wing is connected with the headlock hanging piece through the sliding groove structure. The wing and the headlock assembly in the utility model are the conventional structure of the safety helmet at present, the connection and cooperation of the wing and the headlock hanging piece are also the conventional connection structure, and the wing is connected and fixed through the sliding groove structure.

[0011] Therefore, the hidden headlock fixing structure has the following advantages: the product structure is optimized, the headlock structure can be quickly and stably fixed on the helmet under the limitation of special helmet shape or mold, the application range is wide, higher use demand of users can be met, user experience is optimized, and installation is convenient and fast.
