Detailed Description

The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of facilitating understanding and understanding of the technical solutions of the present invention. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present embodiment provides a multifunctional safety helmet, as shown in fig. 1, comprising a cap body 100, a vent 110 disposed at a front end of the cap body 100, and a functional component disposed at the vent 110 of the cap body 100, wherein the functional component may be a fan or an illumination lamp 200. When the functional element is a fan, the fan blows air towards the interior of the safety helmet, and air flow can enter the interior of the safety helmet through the vent holes 110, so that the head of a person is cooled, the possibility of heatstroke in high-temperature operation is reduced, and the amount of downward flow of sweat is reduced. When the function member is the illumination lamp 200, the illumination lamp 200 is disposed to face the housing to illuminate the front area of the person for the work.

The functional element is detachably fixed to the cap body 100 by a fixing structure of the cap body 100. This allows different functional elements to be mounted on the cap 100, for example the cap 100 can be switched between the light 200 and the fan.

The power supply of the functional element can be integrated on the functional element and can also be arranged on the safety helmet. For example, the lighting lamp 200 includes a housing, a battery, a lamp head and a transparent glass are disposed in the housing, the battery supplies power to the lamp head, light is emitted from the transparent glass after the lamp head emits light, a switch is disposed on the housing to control the lamp head to be turned on and off, and the lighting lamp 200 is detachably connected with the cap body 100 through the housing. For another example, the battery is disposed on the brim of the cap body 100, and the positive and negative electrodes are electrically connected to the sidewall accommodating the functional element through the lead wires, so that the positive and negative electrodes of the functional element are correspondingly connected to the positive and negative electrodes on the cap body 100, and the battery on the brim can supply power to the functional element.

The fixing structure may be a thread structure, that is, an internal thread is provided on the cap body 100, and an external thread is provided on the functional member to form a thread detachable fit. Referring to fig. 2-4, the fixing structure of this embodiment includes a fixing portion 120 located at the periphery of the vent 110, the fixing portion 120 protrudes forward, the fixing portion 120 is ring-shaped, two side walls of the fixing portion 120 have a fastening hole 121, the cap body 100 swings to connect with a buckle 130, the functional component is provided with a slot 210, the buckle 130 can pass through the fastening hole 121 and be embedded into the slot 210, and an elastic component for driving the buckle 130 to be embedded into the slot 210 is disposed between the buckle 130 and the cap body 100. The buckle 130 includes a first swing arm 131 and a second swing arm 132, the first swing arm 131 and the second swing arm 132 are disposed corresponding to the two buckle holes 121, and both the first swing arm 131 and the second swing arm 132 are swingably connected to the cap body 100. For example, two mounting posts 140 are provided on the cap body 100, the first swing arm 131 and the second swing arm 132 swing around the mounting posts 140, respectively, and the elastic member provided between the first swing arm 131 and the mounting posts 140 is a torsion spring.
