Abstract
The utility model relates to a kind of light comfort type safety cap, comprises cap shell, two film layers, protective lining and hat lining, and described protective lining is between two film layers, and the fabric fibre that protective lining was soaked by STF is made.The utility model is light, soft, warmth retention property is good, there is the wearing comfort identical with common fabric cap, but when it can be instantaneous hardening when running into high-altitude hard object and clashing into, utilize the shear thickening liquid in protective lining absorb and dissipate foreign impacts energy, protection head is not injured by a crashing object; After external injury disappears, recover light soft condition again, the defencive function taken into account comfortableness and meet when clashing at once.
Description
Technical field
The utility model relates to safety cap technical field, relates to a kind of light comfortable, safety cap that security is good particularly.
Background technology
In industries such as rescue and relief work, building work, colliery, metallurgy.Safety cap is the visual plant of protection construction operation person head safety.Conventional safety cap, primarily of cap shell and banded hat lining composition, leaves certain space between cap shell and hat lining, or arranges some elastic devices.When operation person head is subject to the impact of falling object; safety helmet shell, hat lining is utilized first impulsive force to be decomposed on the whole area of cranium in moment; then utilize the elastic deformation of safety cap each position buffer structure, most of impulsive force absorbs by the structural deterioration of plastic deformation and permission; make the impulsive force being finally applied to person head reduce the scope that can bear, thus play the effect of the head of protection operating personnel.The cap shell material of visual security cap is resisted performance to safety cap entirety and is played an important role, and therefore cap shell is hard shell, how to be made up of metal and rigid plastics.But this causes existing safety cap heavier, simultaneously because cap body is hard and non-deformable, the non-constant of wearing comfort, to such an extent as to during real work, many operating personnels are unwilling to wear always, in operation process of being everlasting, safety cap are removed.
Summary of the invention
In order to existing safety cap is heavy, wear uncomfortable problem, the utility model provides a kind of light comfort type safety cap.
The utility model is achieved through the following technical solutions.
A kind of light comfort type safety cap, it is characterized in that: comprise cap shell, two film layers, protective lining and hat lining, described protective lining is between two film layers, and the fabric fibre that protective lining was soaked by STF is made.
Described STF is by nanometer grade silica (nano-SiO
2) etc. molecule be mixed in the stable suspersion liquid that certain base fluid (as mineral oil, ethylene glycol, polyethylene glycol etc.) formed.STF is can the Newtonian fluid of proper flow under normal conditions, and when being subject to slightly shearing, (Millisecond) there will be shear thinning phenomenon, apparent viscosity step-down, mobility grow; When being subject to high-speed impact, apparent viscosity can instantaneously exponentially increase, and becomes hard solid, and storage modulus and Loss modulus increase rapidly, show huge absorption and energy dissipation capacity, and when clash into stop or disappearing after again fast (Millisecond) revert to can the Newtonian fluid of proper flow.
Described two film layers is made up of the elastomeric material that water resistance is good, prevents the STF flooded in protective lining from oozing out.
Described cap shell and hat lining are made up of light, soft elastic fabric.
The beneficial effects of the utility model and advantage are.
1, the low viscosity of normal condition down cut thickening liquid ensures that it can not increase the overall compliance of protection liner and safety cap, and lightweight, wearer feels comfortable and light.
2, based on the characteristic of the STF variable viscosity flooded in protective lining; make safety cap energy when running into falling object from high altitude instantaneous hardening; storage modulus and Loss modulus increase rapidly; show huge absorption and energy dissipation capacity; timely prevention falling object from high altitude; absorb and dissipate impact energy, the head of protection wearer is not injured by a crashing object.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of safety cap described in the utility model.
Fig. 2 is the partial enlarged drawing of A-A sectional view of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with drawings and the specific embodiments; these specific embodiments only unrestricted scope of the present utility model for illustration of the utility model should be understood; after having read the utility model; those skilled in the art is to the amendment of the various equivalent form of value of the present utility model or equivalent replacement; and do not depart from aim of the present utility model and scope, all should be encompassed in the middle of protection domain of the present utility model.
As shown in Figure 2, the utility model comprises cap shell 1, two film layers 2a-b, protective lining 3 and hat lining 4, and described protective lining 3 is between two film layers 2a-b, and the fabric fibre that protective lining 3 was soaked by STF is made.
Wearer is in operation process, when cap shell 1 runs into falling object from high altitude, protective lining 3 is subject to the effect of impulsive force, STF wherein can be instantaneous hardening, storage modulus and Loss modulus increase rapidly, show huge absorption and energy dissipation capacity, stop falling object from high altitude in time, absorb and dissipate impact energy, preventing from injuring head by a crashing object; When danger is eliminated, the STF instantaneous recovery normality again in protective lining 3, safety cap recovers common soft condition again.
Claims (3)
1. a light comfort type safety cap, comprises cap shell, two film layers, protective lining and hat lining, and described protective lining is between two film layers.
2. the light comfort type safety cap of one according to claim 1, is characterized in that: described protective lining is made up of the fabric fibre soaking at STF.
