Radiating.
Shell lower end is arranged on by vent, it is to avoid reduce the structural strength that cover top portion protects position, is ensureing peace
The radiating effect of safety helmet is improved while full cap security performance, the advantage of safety and good heat dissipation effect is had concurrently.
It is of the present utility model to be further arranged to：The safety helmet also include installing rack, on the installing rack one
To fixture block, the outer shell outer wall is provided with and is distributed in a pair of draw-in grooves that the vent both sides are embedded in for the fixture block, the wind
Fan and the power supply are fixedly connected with the installing rack.
It is fixed on installing rack by adopting above-mentioned technical proposal, battery and fan, when fan need not be used, will be pacified
The fixture block shelved is extracted in the draw-in groove from shell, mitigates the weight of safety helmet.When needing to use fan heat radiation, will
In the embedded draw-in groove of fixture block on installing rack so that fan is located at vent.
It is of the present utility model to be further arranged to：The vent is located at the cap shell rear.
The rear of cap shell is located at by adopting above-mentioned technical proposal, vent, workman is when safety helmet is worn from vent
The steam of discharge will not meet other people of left and right.
It is of the present utility model to be further arranged to：The inner shell lower end is provided with the circle inner edge for extending inwardly, the inner edge
Inner ring forms groove after being folded upward at the inner shell inwall, and absorbing sweat sponge is embedded with the groove.
By adopting above-mentioned technical proposal, when perspiration is bonded with inner shell, perspiration is under gravity along inner shell
Wall is slid on the absorbing sweat sponge to groove, is temporarily stored in absorbing sweat sponge, avoid dropping onto when people bows people on the face or eye
In eyeball.
It is of the present utility model to be further arranged to：The cap shell also includes being distributed in the cap shell both sides and dissipates positioned at described
Multiple elastic block rubbers in hot cavity, the elastic block rubber two ends are respectively fixedly connected with the outer casing inner wall and described interior
Shell outer wall.
By adopting above-mentioned technical proposal, when shell is collided by alluvium, there is elastic deformation, bullet after stressed skin
Property block rubber for shell provide support and cushioning effect.
It is of the present utility model to be further arranged to：The elastic block rubber is bonded in the outer casing inner wall and institute by glue
State inner shell outer wall.
It is connected firmly by adopting above-mentioned technical proposal, elastic block rubber.
It is of the present utility model to be further arranged to：The inner shell lower end is welded on the outer casing inner wall.
By adopting above-mentioned technical proposal, it is connected firmly between inner shell and shell.
In sum, this utility model has the advantages that：Using formation radiating cavity between shell and inner shell, then
The cavity that radiates is evacuated by fan so that air-flow is formed in safety helmet, amount of heat is taken away；Secondly, shell is subject to
Temperature is raised after irradiation, radiating cavity is provided with cap shell, it is to avoid shell is transferred heat on inner shell by conduction of heat, is radiated
The conduction of the heat that cavity also can completely cut off on shell；Again, air-flow also can be taken away on outer casing inner wall when by radiating cavity
Heat, lowers the temperature to shell, it is to avoid skin temperature is too high, has reached safety, the effect of perfect heat-dissipating.
