Abstract
A kind of builder's safety cap belongs to building field, is specifically related to the security protection protector that a kind of builder uses; This safety cap comprises cap shell, and cap shell is provided with through hole; Described through hole is divided into epimere (1), middle epimere (2), middle hypomere (3) and hypomere (4); Epimere (1) from top to bottom diameter of section reduces successively, and diameter of section is constant from top to bottom for middle epimere (2), and middle hypomere (3) from top to bottom diameter of section increases successively, and diameter of section is constant from top to bottom for hypomere (4); Epimere (1) bottom is identical with middle epimere (2) top cross-section diameter, and middle epimere (2) bottom is identical with middle hypomere (3) top cross-section diameter, and middle hypomere (3) bottom is identical with hypomere (4) top cross-section diameter; The utility model builder safety cap, on the basis keeping anti-gray function, has good gas permeability, builder is worn more comfortable.
Description
Technical field
A kind of builder's safety cap belongs to building field, is specifically related to the security protection protector that a kind of builder uses.
Background technology
Safety cap is the protective articles preventing alluvium from injuring head.Be made up of cap shell, hat lining, lower cheekstrap and rear hoop.Cap shell is hemispherical, firm, smooth and have certain elasticity, and the impact and the puncture kinetic energy that hit thing bear primarily of cap shell.Leave certain space between cap shell and hat lining, available buffer, dispersion instantaneous impact, thus avoid or alleviate the direct injury to head.
Present stage, safety cap is closed design, and the inside and outside cap shell that cannot pass through being exactly safety cap carries out alternately, and this makes the permeability of safety cap bad.And safe wearing cap mostly be physical labourer, perspire a lot, therefore have impact on the wearing comfort of safety cap.
Utility model content
In order to solve the problem, the utility model devises a kind of builder's safety cap, and this safety cap, on the basis keeping anti-gray function, has good gas permeability, builder worn more comfortable.
The purpose of this utility model is achieved in that
A kind of builder's safety cap, comprises cap shell, cap shell is provided with through hole; Described through hole is divided into epimere, middle epimere, middle hypomere and hypomere; Epimere from top to bottom diameter of section reduces successively, and middle epimere from top to bottom diameter of section is constant, and middle hypomere from top to bottom diameter of section increases successively, and hypomere from top to bottom diameter of section is constant; Identical with middle epimere top cross-section diameter bottom epimere, identical with middle hypomere top cross-section diameter bottom middle epimere, identical with hypomere top cross-section diameter bottom middle hypomere.
Above-mentioned builder's safety cap, described middle epimere is straight tube.
Drier is placed with in the middle of described middle epimere.
Above-mentioned builder's safety cap, described middle epimere is helical form or turnover shape.
Above-mentioned builder's safety cap, described hypomere is placed with foam-rubber cushion or foam.
Described foam-rubber cushion or the lowermost end of foam stretch out along cap shell normal direction from cap shell surface.
Beneficial effect:
The first, owing to being provided with through hole on cap shell, therefore there is good gas permeability;
The second, because through hole is followed successively by thick, thin, thick design from top to bottom, therefore anti-gray function can be kept.
Accompanying drawing explanation
Fig. 1 is the utility model builder helmet structure schematic diagram.
In figure: hypomere, 4 hypomeres in epimere, 3 in 1 epimere, 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is described in further detail.
Specific embodiment one
Builder's safety cap of the present embodiment, structural representation (only draws a through-hole structure and neighborhood part cap shell thereof) as shown in Figure 1.This safety cap comprises cap shell, and cap shell is provided with through hole; Described through hole is divided into epimere 1, middle epimere 2, middle hypomere 3 and hypomere 4; Epimere 1 from top to bottom diameter of section reduces successively, and diameter of section is constant from top to bottom for middle epimere 2, and middle hypomere 3 from top to bottom diameter of section increases successively, and hypomere 4 from top to bottom diameter of section is constant; Identical with middle epimere 2 top cross-section diameter bottom epimere 1, identical with middle hypomere 3 top cross-section diameter bottom middle epimere 2, identical with hypomere 4 top cross-section diameter bottom middle hypomere 3.
Specific embodiment two
Builder's safety cap of the present embodiment, on the basis of specific embodiment one, in limiting further, epimere 2 is straight tube, and is placed with drier in the middle of middle epimere 2.This being designed with is beneficial to absorbing sweat.
Specific embodiment three
Builder's safety cap of the present embodiment, on the basis of specific embodiment one, in limiting further, epimere 2 is helical form.This design can prevent dust from falling into hair at the beginning of through hole, improves the effect of anti-gray further.
Specific embodiment four
Builder's safety cap of the present embodiment, on the basis of specific embodiment one, in limiting further, epimere 2 is helical form or turnover shape.This design can prevent dust from falling into hair at the beginning of through hole, improves the effect of anti-gray further.
Specific embodiment five
Builder's safety cap of the present embodiment, on the basis of above embodiment, limits hypomere 4 further and is placed with foam-rubber cushion.The lowermost end of described foam-rubber cushion stretches out along cap shell normal direction from cap shell surface.This design, can increase the function of absorbing sweat, and the contact area of safety cap and head will be diminished because of adding through hole, simultaneously when facing a danger, and many buffer protections.
Specific embodiment six
Builder's safety cap of the present embodiment, on the basis of above embodiment, limits hypomere 4 further and is placed with foam.The lowermost end of described foam stretches out along cap shell normal direction from cap shell surface.This design, will make the contact area of safety cap and head diminish because of adding through hole, simultaneously when facing a danger, and many buffer protections.
The utility model is not limited to above-mentioned preferred forms; anyone should learn the structure change or method improvement made under enlightenment of the present utility model; every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
