The elastic band has the elasticity function and is used for adjusting the wearing elasticity, and the stay wire penetrates through the inner part of the elastic band; the elastic band and the back weaving band are woven together; the rear woven bag is double-layer woven cloth, the stay wire penetrates through the two side cloth, and the tail end of the stay wire is fixed on the woven cloth; the back support is made of soft materials such as pu-back tpu and the like, and is adhered to the middle of the back woven belt to provide the support comfort level of the hindbrain part of a user; the stay wire is annular, a nylon rope or a steel wire rope, the tail end of the stay wire is fixed in the double-layer woven cloth, the tail end of the left stay wire is fixed at the right end of the rear woven belt, the tail end of the right stay wire is fixed at the left end of the rear woven belt, and the front end of the stay wire is hung on the gears at two sides and surrounds the shafts of the gears; the runner group can contain runner, gear and screw, and the gear is stirred to the runner and is rotated, and the gear cooperates with the tooth's socket on the preceding support, has the locking effect, and the gear just can rotate when only rotating the runner. The rotating wheel and the gear are sleeved on the screw column supported in front and fixed by screws. The front end of the pull wire is hung on the wire hanging buckle of the gear and then wound on the winding post of the gear. The gear rotates to enable the stay wire to be wound or loosened, so that the stay wire is tightened, and then the length of the braided belt is tightened. Therefore, the elastic band provides the initial tightening action, and the rotating wheel drives the stay wire to provide the final tightening and loosening and realize the locking. Except the front support, the other parts are soft and can be folded and stored, so that the volume is reduced.
In one example, the headband apparatus structure may be mainly composed of a front support part, a rear braid (rear connection part), a rear support, left and right pull wires (pull wire part), left and right pulley groups (pulley group part).

The rotating wheel and the gear are sleeved on the screw column supported in front and fixed by screws. The front end of the pull wire is hung on the wire hanging buckle of the gear and then wound on the winding post of the gear. The gear rotates to enable the stay wire to be wound or loosened, so that the stay wire is tightened, and then the length of the braided belt is tightened. Therefore, the elastic band provides the initial tightening action, and the rotating wheel drives the stay wire to provide the final tightening and loosening and realize the locking. Except the front support, the other parts are soft and can be folded and stored, so that the volume is reduced.
It should be understood that the retracting action of the pulling wire can be realized by the pulling wire and the rotating wheel set in the embodiment of the application. If the current size is larger, the stay wire is longer, and the redundant stay wire is tightened through the rotating wheel set. If the current size is small, a portion of the pull cord may be paid out from the double braided strap.
In an embodiment of the present application, there is provided an adjustable headband apparatus capable of ensuring lightness and storage of the headband apparatus while improving adjustability and comfortable wearability by employing elastic members such as an elastic band and a headband apparatus of a rotating wheel group member.
It will be understood that where an element is described in embodiments herein as being "secured to" another element, it can be directly or indirectly secured to the other element; similarly, an element described in an embodiment of the present application as "connected" to another element may be directly connected or indirectly connected.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
