It is formed with two symmetrical inclined plates 213 of two sides, the width of upper side plate 211 is less than the width of lower side plate 212.Upper side plate 211 pastes
Conjunction is fixed on cardboard layer 1, and the lower fitting of side plate 212 is fixed on lower cardboard layer 3, is set between adjacent two upper side plates 211
It is equipped with gap, together, the power that a certain hollow paper tube 21 is subject to is dispersed to other for lower 212 end abutment of side plate of adjacent two
Hollow paper tube 21, reduce the pressure that single hollow paper tube 21 is subject to, enhance the structural strength of core layer 2.Inclined plate 213 is under
Angle between side plate 212 is 45 °, both can guarantee that inclined plate 213 had enough support strengths, the hollow paper tube 21 of adjacent two is not
It can mutually limit, it is convenient that cardboard is folded.Interior stiffening plate 200 is folded into square, two skies at break in the present embodiment
The inclined plate 213 of insides cylinder 21, which can push against, to fit together, and without being squeezed and deformed, reduces the structure damage at fold point position
It is bad, keep the structural strength of interior stiffening plate 200 higher.
The inside of hollow paper tube 21 is additionally provided with strengthening core 4, and to promote the structural strength of hollow paper tube 21, strengthening core 4 is adopted
With cardboard identical with hollow 21 material of paper tube, upper and lower ends are connected to respectively to be against on side plate 211 and lower side plate 212.Add
Strong core 4 uses a V-board, and V-board is opening up, and lower end tip is connected to the intermediate position of lower side plate 212, on two sides
End is against the both ends of side plate 211, and the position with 213 angle of inclined plate will be divided into three triangles in hollow paper tube 21.Corrugation
For cardboard when being pressurized, two sides of V-board are blocked by inclined plate 213 will not be mobile to two sides, can be supported on lower side plate 212 with it is upper
Between side plate 211, enhance the support strength of corrugated board.
In order to increase the anti-tear ability of corrugated board, anti-tear layer is additionally provided between core layer 2 and lower cardboard layer 3
5, since the lower side plate 212 mutually abutted forms complete one layer, by the setting of anti-tear layer 5 in lower side plate 212 and lower cardboard layer 3
Between, anti-tear layer 5 is the nylon grid being woven by warp and weft, is connected to lower side plate 212 and lower cardboard by viscose glue
On layer 3, the length direction of the warp and weft of anti-tear layer 5 and lower side plate 212 is in 45 ° of angles, makes corrugated board in transverse direction
It is more difficult to be torn with the containing on longitudinal direction all by the warp and weft of anti-tear layer.
The utility model corrugated case is in production, before interior stiffening plate 200 is installed with external reinforcing plate for car 300 and cabinet 100,
Glue-line first is smeared on incline 102 or interior stiffening plate 200 and external reinforcing plate for car 300, by interior stiffening plate 200 and external reinforcing plate for car 300
It is pasted on cabinet 100, nail case is then carried out by fixing piece 400 again and is fixed, interior stiffening plate 200 and external reinforcing plate for car 300 are made
It installs stronger.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
