Description
Technical field
The utility model relates to a kind of container technology field, relates in particular to a kind of freight container hinge, also relates to the bi-directional foldable freight container based on this hinge.
Background technology
Foldable container is the platform based container that a kind of headwall can fold.It is made up of a platform-type underframe and the headwall that is positioned at these underframe two ends, and the bottom of headwall is connected with platform-type underframe by two hinges.Folding carton can be folded in headwall on the platform when return transport or storage, and the folding back of a plurality of folding cartons pile has advantages such as the storage area of saving and efficient transportation together.
Existing Foldable container mainly is that the headwall unidirectional-folding is that headwall is merely able to freight container folding in case, the folding effect of the headwall of Foldable container depends primarily on the hinge that connects headwall and underframe, Fig. 1 shows a kind of freight container hinge of prior art, and it mainly comprises inner hinge 1, outer hinge 2, pivot 3 and lock shaft 4.When being applied to Foldable container, captive joint with headwall in the top of inner hinge 1, and outer hinge 2 is captiveed joint with the underframe end by base angle part 6, and is articulated by pivot 3.The top of outer hinge 2 is fixed with a L type counterflange spare 5, and as shown in Figure 2, this L type counterflange spare 5 is made of a roof 51, an end wall 52, and roof 51 constitutes an integral body with 52 vertical linking to each other of end wall, and is L-shaped.Roof 51 is provided with the notch 53 that can pass through for inner hinge 1, and the width of notch can hold to receive and be used for handling, bonded assembly ISO twist lock, and end wall 52 is provided with stomidium 54.This hinge is by being located at the fixing inner hinge 1 of lock shaft 4 between inner hinge 1 and the outer hinge 2, thus the headwall of locking folding carton.For some specialities of transportation, during such as products such as power actuated vehicles, people often wish directly product to be reached on the freight container by ramp, perhaps directly open from the Foldable container two ends, and without lifting appliance.Because the outer face of the L type corner fittings of hinge shown in Figure 1 is an osed top and non-dismountable, inner hinge 1 and headwall can not fold outward, therefore headwall must be dismantled, cargo handing is perhaps carried out by the assistance with hill road as ramp in the end that headwall is placed on the folding carton underframe then.This method needs handling appliance or other accessory equipment that headwall is hung chassis of container, and inconvenience when operating in the open air is dangerous, inefficiency.
The patent No. be GB2295381 patent disclosure a kind of folding carton of bi-directional foldable, by means of a kind of freight container hinge of bi-directional foldable, headwall can be folding to the casing outer end, forms the slope of lade.As shown in Figure 3, notch 23 places of inner hinge 1 between two brace panels 22, notch 23 is through, inner hinge 1 can rotate with pivot 3 and lock shaft 4 respectively, thereby headwall can be folded in case and outside the case, when folded-out, form the ramp of lade.When headwall was inwardly folding, as shown in Figure 4, the notch 23 between two brace panels 22 becomes to hold received twist lock and as the hole of handling, and at this moment inner hinge 1 can play position-limiting action to twist lock between notch 23.But the defective that the bi-directional foldable freight container exists in being somebody's turn to do is in the process of handling, and suspender can often clash into inner hinge 1, makes its damage; Because two brace panels 22 are parts independently, only are connected with the sidewall 21 of outer hinge respectively, become isolated cantilever structure, can deform when sidewall is subjected to impacting, and influence the work of twist lock, deform easily in the handling process, safety misadventure occurs; In addition because two brace panels form is the groove structure, it is spacing to be not easy to that suspender is carried out front and back, can not realize quick operation.
In sum, there is defective in two kinds of freight containers of prior art with hinge, are further improved.
Summary of the invention
