Description
Technical field
The invention belongs to public safety defense equipment technical fields, and in particular to a kind of inside and outside support bullet for flexible explosion-proof
Property composite construction.
Background technique
Due to explosive terror attack in some countries, the world commonplace and in rising trend, explosive terror attack situation
It is very severe, it takes precautions against extremely difficult.Explosion terrorist activity has extremely strong concealment, rapidity, randomness, and explosive launches place
And environment ambiguity, the mobile triggering of explosive is random, is difficult to judge its detonation mode.These features promote explosion-proof anti-terrorism portion, various countries
Door requires site disposal suspected explosive to be not directly contacted with explosive as far as possible, and needs quick the cover, avoids instantaneously explosion pair
Personnel and the injury of public property bring and damage.Traditional Explosion-Proof Tank (ball, tank, fence) due to quality weight, be not suitable for individual soldier or
Double movable disposal, and its own is also easy to produce secondary fragment after big TNT equivalent explosive charge.
Summary of the invention
In view of this, the present invention provides a kind of inside and outside support elastic composite structures for flexible explosion-proof, small with wall thickness,
Small in size, light in weight, convenient for the feature of artificial light movement, be easy to rapid the cover explosive or suspected explosive.
The present invention is achieved through the following technical solutions:
Kind is used for the inside and outside support elastic composite structures of flexible explosion-proof, comprising: inner support and outer support；
The inner support and outer support are the cylinder of both ends open, and the bottom end of inner support is equipped with the horizontal folding edge of outward bending, outside
The top of support is equipped with the horizontal folding edge to bend inwards；
The outer support coaxial package is in the outside of inner support, and the horizontal folding edge of inner support is connect with the bottom end of outer support, outer support
Level folding edge is connect with the top of inner support；Thus the excircle of inner support, the excircle of outer support, the horizontal folding edge of inner support end and outer
The horizontal folding edge of support end surrounds closed toroidal cavity；
The inner support and outer support are all made of polyurethane material and are made；
The inner support and the inside and outside periphery of outer support spray the coating of resilient material.
Further, the inner support and outer support are the identical round table-like shell of cone angle.
Further, the inner support and outer support are cylindrical shell.
Further, the elastic material of the coating is polyureas.
Further, the inner support is Nian Jie using glue with the junction of outer support.
It is made, has the characteristics that light-weight the utility model has the advantages that (1) inner support of the invention is all made of polyurethane material with outer support；
And it is coated with polyureas in the inner and outer surfaces of inner support and outer support, so that inner support and outer support form ultra-strong elasticity complex, have super
The characteristics of elasticity, softness, energy load；Therefore, the present invention had not only been structure-bearing body but also had been the light flexible body of flexible explosion-proof, and just
In movement, can be realized flexible explosion-proof, solve the great public safety accident that in emergency circumstances explosive explosion causes, avoid to
The property and the person of the people causes huge damage, and avoids metal rigidity Explosion-Proof Tank (tank, fence) in conventional explosion-proof equipment,
Under big TNT equivalent explosive, the drawbacks of secondary steel drum explosion is crushed (object) fragmentation is generated.
(2) inner support of the invention and outer support can split and cooperate mutually, form a kind of fast group of Quick Release made of nonmetallic
Super-elasticity complex structure body is filled, convenient for assembling and movement.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Embodiment 1:
A kind of inside and outside support elastic composite structures for flexible explosion-proof are present embodiments provided, referring to attached drawing 1-3, comprising:
Inner support 1 and outer support 2；
The inner support 1 and outer support 2 are round table-like shell, and inner support 1 is identical with the cone angle of outer support 2；The big end of inner support 1 is equipped with
The horizontal folding edge of outward bending, the small end of outer support 2 are equipped with the horizontal folding edge to bend inwards；
2 coaxial packages of the outer support are in the outside of inner support 1, and the horizontal folding of inner support 1 passes through glue along the big end with outer support 2
Bonding, the horizontal folding of outer support 2 is along Nian Jie by glue with the small end of inner support 1；Thus the excircle of inner support 1, it is outer support 2 outer circle
Week, the level folding edge of 1 end of inner support and the outer horizontal folding edge for supportting 2 ends surround closed toroidal cavity 3；
The polyurethane material that the inner support 1 and outer support 2 are all made of lightweight is made；
The inner support 1 and the inside and outside periphery of outer support 2 are coated with the coating of one layer of elastic material, the elastic material
For polyureas；Inner support 1 and outer support 2 after spraying form ultra-strong elasticity complex；
When needing to carry out technological processing for explosion protection feature, inside and outside support elastic composite structures are covered in the outside of explosive, explosive explosion
Afterwards, inside and outside support elastic composite structures can resist the fragment that the impact that explosion generates involves generation.
Embodiment 2:
Another inside and outside support elastic composite structures for being used for flexible explosion-proof are present embodiments provided, referring to attached drawing 4-6, in addition to
Inner support 1 and outer support 2 are other than cylindrical shell, and inner support 1 and the outer structure for supportting 2, material and connection are same as Example 1.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
