Abstract

The invention relates to a reinforced proof box, which comprises a box body and a door matched with the box body. The box body comprises a casing and an internal bladder. Between the outer surfaces of the bladder and the inner surfaces of the casing, a filling space for the box body is provided. The proof box is characterized in that, in the filling space, some layered filler formed by lapping plank layers and steel-sheet layers alternatively is filled. As the sandwich layer is an alternative structure of plank, steel sheet and door plate, as their materials are different, the difficulty will increase when a lawbreaker drills the box body with a gun drill to break the box body, this can effectively prevent the breakage of the box by a gun drill; when a lawbreaker breaks the box body by a flame cutter, as the plank is easy to burn, the flame from the head of a cutter will make the plank burn in the filler, this will speed up the heating of the head of the cutter, so the strength of the cutting head will reduce, and the subsequent cutting becomes difficult, this can effectively prevent any lawbreaker to cut break the box body.

Description

A kind of enforced safe

Technical field

The present invention relates to a kind of strongbox, relate in particular to the better enforced safe of a kind of intensity.

Background technology

For making strongbox have superpower intensity, strengthening the antitheft and excellent fireproof performance of strongbox, the casing of traditional strongbox and door-plate generally by steel plate by being welded, or two-layer slightly between the steel sheet cement injection or other material form.

As a patent No. is that the Chinese utility model patent " strongbox " of ZL95208144.X (notification number is CN2224900Y) has disclosed the structure so a kind of, it is by shell, internal box and be located at concrete between shell, the internal box etc. and form, can effectively prevent the impact of drill gun and crow bar, advantage such as security performance is good.

Be that the Chinese utility model patent " strongbox " of ZL200420028238.7 (notification number is CN2668790Y) has disclosed the structure so a kind of also as a patent No., it includes outer container and interior case, interior outer container all is watertight casing, and can load heat-barrier materials such as sandy soil or cement in the space between the interior outer case, thereby have waterproof, flameproof effect.

Though cement injection or other heat-barrier material between interior case and outer container, can strengthen the intensity of strongbox to a certain extent, but the packed layer structure of cement can not the fine lawless person of stopping be used the destruction of drill gun or flame cutting, so the safety of this strongbox also can be done further raising.

Summary of the invention

Technical problem to be solved by this invention is the enforced safe that a kind of anti-drilling, anti-cutting performance is provided at above-mentioned prior art present situation, further strengthens the theftproof performance of this strongbox.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of enforced safe, the door body that includes casing and match with casing, described casing is made up of shell and inner bag, have the casing packing space between each inner surface of each external surface of inner bag and shell, it is characterized in that being filled with in the described casing packing space and be stacked alternately the stratiform casing filler that forms by plank layer, steel plate layer.

Be further to strengthen anti-drilling, the anti-cutting function of casing, in the above-mentioned stratiform casing filler with shell and the contacted plank layer that is of inner bag.After destroying shell, flame cutting machine just directly destroys the plank layer, the rifle head of cutting machine can make the plank grate firing burn when flame cuts, the rapid rubescent heating of cutting machine gun head, reduce the cutting intensity of cutting machine gun head, after cutting machine gun head enters into the steel plate layer, its destructive power reduces, if also be the plank layer at last, then further reduce the intensity of cutting machine gun head, rifle head intensity in destructive process weakens gradually, make it can not destroy bladder layer in the casing, effectively hinder the lawless person with the destructive process that uses flame cutting machine to casing.Because inner bag and shell are steel plate material, so the interlayer outermost layer is the conversion variation increase that the plank layer can make plank and steel plate layer replace, therefore in the process of using drill gun to destroy, because material is different, and change many relatively, the drilling difficulty increases, and the steel sheet of internal layer is if anti-drilling steel plate, and effect will be better.

Above-mentioned stratiform casing filler can have three layers, is followed successively by plank layer, steel plate layer and plank layer.Above-mentioned stratiform casing filler also can have nine layers, is followed successively by plank layer, steel plate layer, plank layer, steel plate layer, plank layer, steel plate layer, plank layer, steel plate layer and plank layer.The number of plies of stratiform casing filler designs as required, and the many more safeties of the number of plies are good more certainly, but relative cost is also high.

For making a body also have good anti-drilling, anti-cutting function, above-mentioned door body inside has a body packing space, is filled with by plank layer, steel plate layer in the described door body packing space and is stacked alternately the stratiform door body filler that forms.

For further strengthening anti-drilling, the anti-cutting function of door body, outermost layer is the plank layer in the above-mentioned stratiform door body filler.

Above-mentioned stratiform door body filler can have three layers, is followed successively by plank layer, steel plate layer and plank layer.Above-mentioned stratiform door body filler also can have nine layers, is followed successively by plank layer, steel plate layer, plank layer, steel plate layer, plank layer, steel plate layer, plank layer, steel plate layer and plank layer.The number of plies of stratiform door body filler designs as required, and the many more safeties of the number of plies are good more certainly, but relative cost is also high.

An above-mentioned door body comprises: the door-plate of cavity is made and had to a steel plate, and one makes liner plate by steel plate, and this liner plate covers cavity so that form packing space between door-plate and the liner plate.

For preventing when welding inner bag and shell, because temperature raises, plank grate firing in the packed layer is burnt, the above-mentioned inner bag outside is weldingly fixed between the outside of shell, is provided with the isolation layer that intercepts shell and stratiform casing filler in the close casing packing space of weld of inner bag and shell.

Compared with prior art, the invention has the advantages that: because interlayer is plank, steel plate, door-plate alternating structure, because material is different, hard when soft when being material, in the process of using drill gun that casing is destroyed, can make the lawless person use drill gun drilling casing difficulty to increase, effectively stop the lawless person to destroy with the drilling of drill gun to casing; When with flame cutting machine when safe body is destroyed, because the incendive characteristic of plank layer, the flame that the rifle head of cutting machine is emerged can make the plank grate firing in the packed layer burn up, quicken the burning heat of cutting machine gun head, the intensity of rifle head reduces, cause continuing the cutting difficulty, effectively stop the cutting damage of lawless person casing.
