Abstract
The utility model proposes a kind of heat radiation helmet, comprise shell, inner casing, nut, bolt, through hole, groove; It is characterized in that: described groove is arranged on described case surface, described through hole is arranged on described inner housing surface, and described shell adopts bolts and nuts to be connected with the top of described inner casing; When described through hole aligns with described groove described through hole breathe freely, described through hole and described groove unjustified time described through hole airtight.Compared with prior art, the beneficial effects of the utility model are: when described through hole aligns with described groove, described through hole is breathed freely, and plays thermolysis, can prevent silt from falling into the helmet when not lining up, convenient and practical.
Description
Technical field
The utility model relates to a kind of helmet, particularly a kind of heat radiation helmet.
Background technology
Workpeople's safe wearing cap work on construction site, conventional safety cap radiating effect is poor, affects workman and normally works.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of heat radiation helmet.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat radiation helmet, comprises shell, inner casing, nut, bolt, through hole, groove; It is characterized in that: described groove is arranged on described case surface, described through hole is arranged on described inner housing surface, and described shell adopts bolts and nuts to be connected with the top of described inner casing.
Preferably, when described through hole aligns with described groove described through hole breathe freely, described through hole and described groove unjustified time described through hole airtight.
Compared with prior art, the beneficial effects of the utility model are: when described through hole aligns with described groove, described through hole is breathed freely, and plays thermolysis, can prevent silt from falling into the helmet when not lining up, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment through hole and groove aligned condition schematic diagram.
Fig. 2 is the utility model embodiment through hole and the unjustified view of groove.
In figure 1, shell 2, inner casing 3, nut 4, bolt 5, through hole 6, groove.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described further:
Embodiment
As shown in Figure 1, 2, a kind of heat radiation helmet, comprises shell 1, inner casing 2, nut 3, bolt 4, through hole 5, groove 6; It is characterized in that: described groove 6 is arranged on described shell 1 surface, described through hole 5 is arranged on described inner casing 2 surface, and described shell 1 adopts bolt 4 to be connected with nut 3 with the top of described inner casing 2.
When being alignd with described groove 6 by described through hole 5, described through hole is breathed freely, and now by described bolt 4 and described nut 3 rotational lock, plays thermolysis when wearing; Described bolt 4 is rotated loosening with described nut 3, described shell 1 is relatively rotated with described inner casing 2, make the part described shell 1 not being arranged groove 6 cover described through hole 5, then by described bolt 4 and described nut 3 rotational lock, described through hole 5 no longer dispel the heat.
In radiation processes, if there is silt to drop, also can rotate loosening with described nut 3 by just described bolt 4, described shell 1 is relatively rotated with described inner casing 2, the part described shell 1 not being arranged groove 6 is made to cover described through hole 5, again by described bolt 4 and described nut 3 rotational lock, described through hole 5 is plugged, and prevents silt from falling into the helmet.
Above, be only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
