Description
Technical field
The present invention relates to technical field of safety protection, buffer to when hitting by deviation with fine more particularly, to one kind
The shock resistance safety cap of protective action.
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 shell
Fragmentation or by the shock resistance safety cap high with fine buffer function, security performance when being biased to percussion.
The present invention is for achieving the above object the technical scheme adopted is that a kind of shock resistance safety cap, including shell
Body, the outer housing is interior to be equipped with liner, and the liner includes the lateral surface outer liner fixed with outer housing and is arranged in outer lining
The inner liner of inside is padded, the outer liner is the high density foaming structure of integration, and the inner liner is the low of integration
Density foaming structure, the setting fastening band of safety cap are arranged in inner liner, be equipped between outer liner and inner liner safety cap by
It is biased to the soft rubber cushion for sliding outer liner relative to inner liner when impact, the lateral surface of the soft rubber cushion and the medial surface of outer liner
Bonding, the medial surface of soft rubber cushion and the lateral surface of inner liner are Nian Jie.Safety cap of the invention is equipped with high density in outer housing and sends out
The outer liner of bubble structure is avoided using the harder characteristic of the high density of outer liner, quality when outer housing is when by hitting damaged
Safety cap is directed through, and weight is avoided directly to impact user head.And the inside inner liner of outer liner using low-density,
The relatively soft material of structure for absorbing impact energy and dispersion shock loading, while meeting wanting for user's comfortable wearing
It asks.High resiliency soft rubber cushion between outer liner and inner liner can not only play the buffer function that safety cap vertically impacts, but also can be with
When safety cap is kept outer liner sliding relative to inner liner together with outer housing by when being biased to impact using the function that it is easily deformed
Dynamic, under the tangential flexible deformation effect of soft rubber cushion, outer liner can rotate certain angle relative to inner liner together with outer housing
Degree, to play the role of greatly reducing the unexpected rotation on user head when being biased to impact to damping of shocks is biased to, avoiding making
Its head is shaken or contusion.Here vertical impact refers to the impact of the radial direction (normal direction) of spherical shell shape safety cap,
It is biased to impact and refers to the impact deviateed vertically with component in spherical shell shape safety cap tangential direction.In this way, the present invention solves mesh
There are lose protective action when shell fragmentation completely, be easy to drive user's head when by percussion is biased to for preceding safety cap
Portion rotates suddenly and shakes its head or the problem of contusion, and the present invention is in external shell of safety helmet fragmentation or by being biased to rush
Have fine buffer function, security performance high when hitting effect, substantially increases protective effect of the safety cap to user.
