Abstract

The utility model discloses a safety helmet with good air permeability. The safety helmet comprises a helmet shell which is hemispherical, wherein a plurality of air permeable holes are formed on the outer side of the helmet shell. The safety helmet is used for solving the problem of poor air permeability of the safety helmet in the prior art; and moreover, the safety helmet provided by the utility model is simple in structure, and is convenient to use.

Description

A kind of safety cap of good permeability

Technical field

The utility model belongs to the articles for labour protection field, relates in particular to a kind of safety cap of good permeability.

Background technology

Safety cap is that anti-object hits and the Head protective devices of head impact when falling, and the impact and the puncture kinetic energy that hit thing are mainly born by the cap shell.Leave certain space between cap shell and the hat lining, available buffer, dispersion instantaneous impact, thereby avoid or alleviate direct injury to head, impact absorption performance, puncture-resistant performance, lateral rigidity, electrical insulating property, anti-flammability are the requirements to the basic fundamental performance of safety cap, the dispersive stress effect: the cap shell is ellipse or hemispherical, smooth surface, when object fell on the cap shell, object can not stop immediately landing; And the power of bearing that the cap shell overwhelms is a little transmitted towards periphery; cushion the Li Keda of minimizing more than 2/3 by hat lining; remaining power passes to people's cranium through the whole area of hat lining; so just impetus has been become focusing surface; thereby avoided impulsive force certain some stress on the cap shell to concentrate; it is stressed to have reduced unit are; when operation personnel head is subject to the impact of falling object; utilize safety helmet shell; hat lining decomposes impulsive force first on the whole area of cranium in moment; then utilize the strain of each position buffer structure of safety cap; the structural deterioration of plastic deformation and permission absorbs most of impulsive force; the impulsive force that is applied at last personnel's head is reduced to below the safety index; thereby play the effect of protection operating personnel's head, the regulation safety cap must can absorb 4900N in the GB.This is because biological test; the limit value of human cervical spine maximum when stressed; surpassing this limit value cervical vertebra will come to harm; the lighter causes paralysis; the severe one threat to life; because safety cap is related to the life safety of workmen in the relatively more dangerous working environment such as construction site; so the quality of safety cap is all higher; and safety cap will carry the larger impulsive force of protection; so the thickness of Generally Recognized as safe cap is all thicker, and sealing is very high, and permeability is poor; the safe wearing cap is pleasant in more refrigerant environment; but safe wearing cap in or the environment that The sun is shining fiercely higher in temperature often can allow the workmen with a face streaming with sweat, even can cause heatstroke; therefore there also have some workmens really can't stand to be scorching; remove the safety cap on the head, although more comfortable like this, but there is potential safety hazard; be necessary to provide a kind of safety cap of good permeability, to solve the existing problem of prior art.

The utility model content

The utility model provides a kind of safety cap of good permeability, and in order to solving the relatively poor problem of safety cap gas permeability in the prior art, and the utility model is simple in structure, and is easy to use.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of safety cap of good permeability, comprise the cap shell, and the cap shell is hemispherical, the arranged outside of cap shell has a plurality of air-vents.

Further, the inboard of described cap shell is provided with hat lining, and the lower end of hat lining is fixed on around the shade.

Further, described hat lining is the high material of gas permeability.

Further, described hat lining is the hollow out material.

Further, the lower end of described cap body is provided with hatband.

Compared with prior art, the safety cap beneficial effect of a kind of good permeability of the present utility model is: the arranged outside of cap shell has a plurality of air-vents, increased the gas permeability of safety cap, in order to solve the relatively poor problem of safety cap gas permeability in the prior art, and the utility model is simple in structure, and is easy to use.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, be described in detail as follows.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is upward view of the present utility model.

Among the figure: 1-cap shell, 2-air-vent, 3-hatband, 4-hat lining.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with the drawings and specific embodiments.

Shown in Fig. 1-3, a kind of safety cap of good permeability comprises cap shell 1, and cap shell 1 is hemispherical, and the arranged outside of cap shell 1 has a plurality of air-vents 2.

The inboard of described cap shell 1 is provided with hat lining 4, and the lower end of hat lining 4 is fixed on around the shade.

Described hat lining 4 is the high material of gas permeability.

Described hat lining 4 is the hollow out material.

The lower end of described cap body 1 is provided with hatband 3.

Adopt above technique effect, the arranged outside of the cap shell 1 of the safety cap of a kind of good permeability of the utility model has a plurality of air-vents 2, increased the gas permeability of safety cap, described hat lining 4 is the high material of gas permeability and for the hollow out material, has also effectively increased the gas permeability with the hat lining 4 that contacts with the personnel head of wearing, and is more comfortable, adopt above technical scheme, in order to solving the relatively poor problem of safety cap gas permeability in the prior art, and the utility model is simple in structure, and is easy to use.

Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment; its concrete steps allow to change; in addition; the lower implementation that has other of the utility model that coexists design; need to prove, the preferred version that above-described embodiment is only realized for the utility model, and non-limiting exhaustive; without departing from the concept of the premise utility, any apparent replacement is all within the utility model protection domain.
