Description
Technical field
The present invention relates to technical field of safety protection, are rushed more particularly, to one kind in external shell of safety helmet fragmentation, vertically
Hit and be biased to the multiple protective safety cap that fine buffer function is all had when impact.
Background technique
Safety cap is the essential safety protective tools of the construction enterprises such as building safety in production.The safety cap of the prior art
The liner belt of a shell and setting inside the shell is generally included, is wherein cavity between liner belt and shell, does not protect
Layer.Although this safety cap can play certain protective action, when the shock by sharp object, shell is easy breakage,
Safety cap just loses protective action completely at this time.On the other hand, the safety cap of the prior art be mainly used for reduce safety cap by
Injury to top falling objects to user head, but actually when a fault occurs, the possibility on the falling objects just hit crown
Less, i.e., a possibility that safety cap bears simple vertical impact force is little, and bigger may be safety cap by falling objects
It is biased to hit, under the action of being biased to hit, the rotation of certain angle occurs in safety cap moment, and the rotation of this moment can band
The unexpected rotation on dynamic user head, so that its head be made to be shaken or contusion.Recently in the research table in brain trauma field
Bright, the shearing force that similar rotary impact generates brain is more much bigger than vertically impacting to the damage of brain cell.Publication date is
On April 30th, 2019, the Chinese patent literature of Publication No. CN109691716A disclose a kind of safety with elastic buffer
Cap, including cap body, cap body include shell and inner casing, are equipped with elastomeric spring between shell inner casing, inner casing upper surface is set
There is supporting layer one, shell lower surface is equipped with supporting layer two.This safety cap with elastic buffer, when weight is fallen in cap body
When, buffering is played the role of by the buffering of elastomeric spring, ensure that safety of the safety cap to human body.But this safety cap
It is cavity between outer housing and liner layer, is not provided with protective layer, when the shock by sharp object, shell is easy breakage, this
When safety cap just lose protective action completely.On the other hand, it when this safety cap is hit by the deviation of falling objects, is being biased to
Under the action of shock, safety cap moment will appear the rotation of certain angle, and the rotation of this moment can drive user head
Unexpected rotation, so that its head be made to be shaken or contusion.Therefore, it is necessary to design a kind of to outside deviation impact force tool
There is the safety cap of more preferable buffer function, to improve the security performance to safety cap.
Summary of the invention
The purpose of the invention is to overcome current safety cap there are lost completely when shell fragmentation protective action, by
To the problem of driving user head to rotate suddenly and make its head injuries is easy when being biased to percussion, one kind is provided in safety
The fragmentation of cap shell is vertically impacted and is biased to all have the multiple protective safety cap of fine buffer function when impact.
The present invention is including outer for achieving the above object the technical scheme adopted is that a kind of multiple protective safety cap
Shell, the outer housing is interior to be equipped with liner, and the liner includes outer liner, interface and inner liner, the outside of outer liner
Face is fixed with outer housing, and interface is located at the inside of outer liner, and inner liner is located at the inside of interface, the outer liner
For the high density foaming structure of integration, interface is the middle density foaming structure of integration, and inner liner is the low of integration
The setting fastening band of density foaming structure, safety cap is arranged in inner liner, is distributed between interface and inner liner and outer liner
Have safety cap by be biased to impact when slide outer housing relative to inner liner multiple soft rubber cushions, the two sides of soft rubber cushion with
Adjacent liner bonding.Safety cap of the invention is equipped with the outer liner of high density foaming structure in outer housing, when outer housing exists
When by hitting damaged, avoiding safety cap from being directed through using the harder characteristic of the high density of outer liner, quality, avoiding weight
Directly impact user head.And the material that the inner liner contacted with user head is relatively soft using low-density, structure, it uses
In absorption impact energy and dispersion shock loading, while meeting the requirement of user's comfortable wearing.In addition, outer liner and inner liner
Between be additionally provided with interface, the density of interface is between outer liner and inner liner, between inner liner and outer liner
Buffer function.Soft rubber cushion is equipped between interface and inner liner and outer liner, this elastomeric soft rubber cushion can both rise
The buffer function vertically impacted to safety cap, and can be when safety cap is by the function of being biased to be easily deformed when impact using it
Slide outer liner relative to interface together with outer housing, interface is then slided relative to inner liner, soft inside and outside two layers
Under the flexible deformation effect of rubber mat, outer liner can rotate certain angle relative to inner liner together with outer housing, to play
Effect to damping of shocks is biased to greatly reduces the unexpected rotation on user head when being biased to impact, avoid making its head by
Concussion or contusion.Here vertical impact refers to the impact of the radial direction (normal direction) of spherical shell shape safety cap, and being biased to impact is
Refer to the impact deviateed vertically with component in spherical shell shape safety cap tangential direction.In this way, the present invention solves current safety cap
There are lose protective action when shell fragmentation completely, be easy that user head is driven to rotate suddenly when by percussion is biased to
And shake its head or the problem of contusion, the present invention in external shell of safety helmet fragmentation, vertically impacted and be biased to punching
Fine buffer function is all had when hitting, and is a kind of safety cap with multiple protection functions.
Preferably, the lateral surface of inner liner and the medial surface of outer liner are spherical structure, interface is hemispherical Shell
The gap of hemispherical shell, the soft rubber cushion are equipped between shape structure, inner liner and interface, interface and outer liner
