For example, a safety helmet 100 configured to be worn by a construction worker. Further, the first side 110 of the safety helmet 100 is installed with a snap plug 120 having the first aperture 202. Further, the first aperture 202 is positioned with the screw element 206 having plurality of threads 212. Further, when the screw element 206 is positioned inside the first aperture 202, a crown 104 having the second aperture 224 is configured to engage with the screw element 206.

[0059] At a second operation, the protrusion 214 of the screw element 206 may configured to be engaged with the cam profile 204 to change the position of the face shield 106. In some embodiments, the second portion 210 of the snap plug 120 may be machined with the cam profile 204. Further, the cam profile 204 may be configured to couple with the protrusion 214 of the screw element 206 while the screw element 206 is positioned within the first aperture 202 of the snap plug 120 and the second aperture 224 of the crown 104. Further, the second portion 210 of the screw element 206 may comprise the block element 226. Further, the block element 226 may be configured to engage with the second aperture 224 of the crown 104. For example, the screw element 206 comprises the protrusion 214. Further, the protrusion 214 is configured to be engaged with a cam profile 204 of the snap plug 120 attached with the first side 110 of the safety helmet 100.

[0060] At a third operation, the protrusion 214 may be configured to move from the first position 218 to the second position 220 of the cam profile 204 to change the position of the face shield 106. Further, the first position 300 of the face shield 106 may correspond to the stowed position. Further, the second position 400 of the face shield 106 may correspond to the used position Further, when the face shield 106 moves to the stowed position, the protrusion 214 may get positioned at the first position 218. Further, when the face shield 106 moves to the used position, the protrusion 214 may get positioned at the second position 220. For example, the protrusion 214 is configured to move to the first position 218 and the second position 220. Further, during the rotations of the protrusion 214 from the first position 218 and the second position 220, a face shield 106 installed with the crown 104 moves from a stowed position to a used position. Further, during the rotations of the protrusion 214 from the second position 220 and the first position 300, the face shield 106 moves from the used position to the stowed position.

[0061] The present disclosure provides various embodiments of a safety helmet 100. Embodiments may be configured to attach the face shield 106 with the safety helmet 100 using the snap plug 120. Embodiments may require fewer components in order to reduce overall manufacturing cost. Embodiments may avoid any accidental or undesired rotation or movement of the face shield 106 with respect to the safety helmet 100 using the one or more grooves 222. Embodiments may be configured to enhance the overall efficiency and productivity by providing a smooth transition between the first position 300 and the second position 400 of the face shield 106. Embodiments may facilitate easy attachment and detachment of the face shield 106 from the safety helmet 100. Embodiments may minimize the effort required to adjust and maintain the face shield 106 in the first position 300 and the second position 400.
