To further ensure that the helmet fits various head shapes, a headband is installed inside the helmet. The headband can be adjusted to fit the user's head, but resizing may cause the helmet to be tilted to the front or back, which will affect the protective effect and the comfort when wearing the helmet. Therefore, adjusting the position of the headband is very important. In addition, the comfort when wearing the helmet is also a goal that needs to be improved. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an improved safety helmet structure, which facilitates the adjustment of the headband position and improves the protective effect and comfort when wearing the helmet.

[0004] To achieve the above objectives, the improved structure of this utility model safety helmet adopts the following technical solution:

[0005] An improved helmet structure includes a helmet and a head strap, wherein:

[0006] The safety helmet has an adjustment part on each side inside, and the adjustment part has a through slot hole. The surface of the safety helmet has at least one ventilation part, and the ventilation part has several ventilation holes to allow air to enter and exit the inside and outside of the safety helmet. The ventilation part has a cover that can be used to cover the ventilation holes. By adjusting the cover, the ventilation holes can be temporarily uncovered to increase breathability.

[0009] In the improved helmet structure described above, the visor is secured to the vent, and removing the visor temporarily allows it to leave the vent unobstructed.

[0010] As described above, the improved helmet structure has a number of locking flanges on the inner side of the helmet and a number of locking grooves in the adjustment part. The adjustment part can be combined with the helmet by locking the locking flanges into the locking grooves.

[0011] In the improved helmet structure described above, the locking part and the locking head are in a T-shape. After the locking head and the locking part pass through the slot hole, they rotate so that the locking head can secure the headband to the adjustment part.

[0012] As described above, in the improved helmet structure, the locking head is truncated conical in shape. The locking part is recessed with a groove so that the locking part can be elastically squeezed through the slot hole. Several flanges are protruding on the inner side of the slot hole to help the locking part slide discontinuously along the slot hole, thereby allowing the position of the headband to be adjusted in stages and preventing slippage.

[0013] In the improved helmet structure described above, the locking part is integrally connected to the headband.

[0014] In the improved helmet structure described above, the locking part is separate from the headband.

[0015] The technical solution provided above has the following beneficial effects:

[0016] First, the safety helmet of this utility model is provided with an adjustment part with a through slot hole and a headband with a locking part. Since the locking part can slide along the slot hole, the position of the headband can be adjusted back and forth, so that the user can obtain better protection from the safety helmet.
