The specific embodiment
In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
See also Fig. 2 to Fig. 4, freight container of the present utility model comprises casing 1 and end door 2.
Can be provided with an interior side wall outer panel 11, an interior doorframe 12, at least one charging manhole (not shown) and at least one negative pressure interface (not shown) on the described casing 1.Described interior side wall outer panel 11 vertically is arranged on the inboard of described casing 1.Described interior doorframe 12 is arranged on the inboard of described casing 1, and when being provided with described interior side wall outer panel 11, one side of interior doorframe 12 can be connected to described interior side wall outer panel 11 towards a side of casing 1 inside.Described charging manhole can be arranged on the top of described casing 1, so that from the charging manhole material of packing into.Described negative pressure interface is used for the air pressure balance inside and outside the guard box when unloading.
Described end door 2 closes the end of described casing 1, and described end door 2 is layer door structure, comprises an inner door 22 that is positioned at outer field two gangway doors 21 and is positioned at internal layer, can also comprise hinge 23, connection structure 24 and sealing joint strip 25.
See also Fig. 2 and Fig. 4, described two gangway doors 21 are external side end and casing 1 structure that the middle part splits that is hinged, and the middle part of two gangway doors 21 can be split to the outside of casing 1.
See also Fig. 3 and Fig. 4, described inner door 22 is the whole single door structure that can open outside case that a side and described casing 1 are hinged, described interior side wall outer panel 11 should be arranged on the inboard position near described inner door 22 1 sides of casing 1, thereby so that a side of described inner door 22 can be hinged on the described interior vertical door pillar 11.The place of the end position when the interior doorframe 12 of described casing 1 inboard should be arranged on and can limit described inner door 22 and close in the case.Can offer at least one on the described inner door 22 can be for the discharging opening 221 of bulk goods discharging, and described discharging opening 221 can be arranged on the described inner door 21 more on the lower side the position of end to make things convenient for discharging.
Described hinge 23 is arranged on position that described inner door 22 and described casing 1 be hinged (when being provided with described interior vertical door pillar 11, this hinge 23 is arranged on described inner 22 position that is hinged with described interior vertical door pillar 11), described hinge 23 can be common simple chain structure (this situation does not have diagram), also can be the dual hinge structure that comprises two hinges 231/232 and two flaps 233/234 as shown in Figure 4.When described hinge 23 was dual hinge structure, one of them hinge 231 was connected between two flaps, and another hinge 232 is hinged one of them flap 233 with described casing 1, and another flap 234 is connected to a side of described inner door 22.This kind dual hinge structure can effectively increase the open angle of described inner door 22 outside case.
