Description
Technical field
The present invention relates to a kind of rigid foldable container that is used to transport goods, be specifically related to a kind of folding carton.
Background technology
Container has just developed into a kind of international means of transport of multimodal transport in the sixties in 20th century as the instrument of shipping.
As shown in Figure 1, very ripe already folding carton 1 generally comprises underframe 10, the end carriage body 11 that is fixedly connected on underframe 10 both ends that is used to place the carrying goods, the hinge 13 that is arranged on end carriage body 11 both sides and the headwall 12 that is connected with hinge 13 and is arranged on a locking device 14 on two lateral surfaces of underframe 10 both sides on the current techniques.
In the folding carton technology, hinge is one of its core technology.Figure 2 shows that current folding carton hinge 13 commonly used, axle 134 and head that this hinge comprises inner hinge 131, outer hinge 132, be used to connect inside and outside hinge are conical taper pin 133, when taper pin 133 passes after correspondence is opened in taper hole on the inside and outside hinge, inside and outside hinge is fixed together, behind the taper hole inside and outside taper pin withdraws from the hinge, inner hinge 131 can rotate around axle 134.
As shown in Figure 3, the underframe 10 of folding carton 1 shown in Figure 1 comprises in the bottom side beams 101 of its both sides and laterally is connected some cross members 102 between two bottom side beams 101; As shown in Figure 4, bottom side beams 101 is by upper flange 1011, lower wing plate 1012 and be erected in straight web 1013 between the lower wing plate and be welded to each other and form.Shown in Fig. 5,6, headwall 12 comprises corner post 121 in its both sides, at the drift angle spare 122 of its two top corner parts, laterally be connected between the top of corner post 121 and top end transverse member 123 and bottom end rail 124 between the bottom and the end wall panel 125 that is arranged in the framework that is constituted by corner post 121, top end transverse member 123 and bottom end rail 124; Fixedlying connected with inner hinge 131 in the bottom of corner post 121, fixedlys connected with base angle part 15 in the bottom of outer hinge 132, fixedlys connected with end carriage body 11 in its side; Thus, by the rotation of inner hinge, headwall 12 can erect and be vertically to underframe 10, also can folded flat be taped against on the underframe 10; The top of outer hinge 132 offers opening 1321, is used to hold receive inner hinge 131 when headwall is erect, and after headwall 12 folds on the underframe, can place twist lock according to the ISO standard in the open top 1321, realizes that the connection between the folding carton of folding pile is hung.Join between folding carton when hanging, the bottom outlet of the base angle part of upper strata folding carton is corresponding with the open top 1321 on the corresponding outer hinge of lower floor's folding carton, then with twist lock according to the ISO standard both lockings is hung to realize connection; At this, shown in Fig. 7,8, because the width M of the bottom outlet 151 of base angle part 15 is limited between the 63mm-65mm by iso standard, so the width of outer hinge open top 1321 (Fig. 6 shows) correspondingly is also within this scope, thus, the width of inner hinge generally is restricted to and is no more than 63mm.
Shown in Fig. 9,10, general folding carton is when assembling, spacing between opening 1321 (as shown in Figure 6) center at outer hinge 132 tops of the same side headwall and the spacing between inner hinge 131 neutral surfaces are L, and L satisfies the requirement of iso standard, generally are about 2260mm.Transport in the process in the loading of folding carton, owing to reason such as jolting, its headwall can be subjected to horizontal push-pull effort.Headwall for as shown in Figure 9 structural integrity, the corner post 121 of headwall 12 is welded to connect with top end transverse member 123 and bottom end rail 124, form the rigidity angle, when drift angle spare 122 bears cross force F, unpper and lower beams 123 and 124, end wall panel 125 with and rigidity angle stragging that forms with corner post 121 and the effect of having born power F, the distortion of drift angle spare 122 mainly is subjected to the stiffness effect of headwall 12 itself, and therefore, inner hinge 131 can satisfy the requirement of rigidity.Under some shipping requires, folding carton need be packed into above the goods of its casing length, at this moment the headwall of folding carton is imperfect structure, as shown in figure 10, also stressed F does the time spent on drift angle spare 122, the structure that inner hinge 131 and corner post 121 and drift angle spare 122 are formed is similar to cantilever beam, the moment of flexure maximum that inner hinge 131 is subjected to, its stress is also maximum, the deformation displacement at drift angle spare 122 places is directly proportional with the distortion angle of inner hinge 131 simultaneously, so inner hinge 131 very little distortion will cause the very big displacement in drift angle spare place.When the inner hinge width is restricted under the wide situation of 63mm by the width of opening 1321 (as shown in Figure 6), the lateral stiffness of inner hinge 131 and intensity are difficult to meet the demands in the ordinary course of things.How to solve the lateral stiffness of the inner hinge under the imperfect condition of headwall structure and strength problem and be the difficult point in such folding carton design.
As shown in figure 11, when headwall 12 vertically the time, from the top of drift angle spare 122 on earth between the bottom surface of corner fittings 15 distance H be the external height of folding carton, and be the internal height of folding carton to the distance h the last plane of underframe 10 from the top of drift angle spare 122.General folding carton is the needs that satisfy international combined transport, when headwall is vertical, all according to the ISO standard the requirements of the external dimensions such as length of casing outside, so, for the certain folding carton of external dimensions, its internal height is often determining the size of folding carton cargo space; And this internal height is by the decision of the thickness of underframe, and the thin more internal height of underframe is big more, and loading is many more, and the strength and stiffness of underframe are also just low more simultaneously; Hereat, reducing underframe thickness with when increasing cargo space, intensity how to strengthen the underframe of reduced thickness is the emphasis that the research staff considers always.
