A kind of side opening door freight container
Technical field
The utility model relates to freight container, in particular, relates to a kind of hermetically-sealed construction of side opening door freight container.
Background technology
As shown in Figure 1, freight container normally side open the door 4 around outer rim fixed gate sealing band 41, door weather strip 41 is resisted against respectively on the underframe 1, top beam of laterally 3, corner post (not marking among the figure) of freight container, realizes the purpose of freight container water-stop.For side opening door freight container, side opening door freight container is behind lade, underframe 1 can produce down owing to the action of gravity of goods and be bent downwardly distortion, make side open the door and 4 produce relative displacement with underframe 1, cause side open the door door weather strip 41 on 4 cooperate with underframe 1 not tight, side open the door 4 and underframe 1 between sealing property descend.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art, and a kind of side opening door freight container is provided.
For achieving the above object, a kind of side opening door freight container, comprise casing, and the side on the casing side, offered open the door, described casing comprises underframe, be located at four jiaos of places of underframe corner posts, connect the top beam of laterally of two corner posts of underframe one side, described side is opened the door between described underframe, top beam of laterally, it is characterized in that the curb girder of described underframe is provided with sealing band, described sealing band is resisted against and forms the bottom sealing surface on the medial surface that described side opens the door.
In the utility model, described sealing band is resisted against on the medial surface of the door crossbeam that described side opens the door and forms the bottom sealing surface.
In the utility model, described sealing band is solid squares vertical bar or square hollow vertical bar or circular vertical bar.
In the utility model, the curb girder equal in length of described sealing band length and described underframe.
In the utility model, described side is opened the door and is provided with gasket, and described gasket forms hermetically-sealed construction with described top beam of laterally, corner post respectively.
The utility model compared with prior art, its beneficial effect is: one, side opening door freight container can not reduce the freight container water sealing property because of underframe flexural deformation behind lade; Its two, simple in structure.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by the specific embodiment of the present utility model is described in detail.
In the accompanying drawing,
Fig. 1 is the side opening door freight container of prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A-A view of Fig. 2;
The specific embodiment
For further setting forth technological means and the beneficial effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
As shown in Figure 2, side opening door freight container, comprise casing, and the side on the casing side, offered open the door 4, casing comprises underframe 1, be located at four jiaos of places of underframe corner posts 2, connect the top beam of laterally 3 of two corner posts 2 of underframe 1 one sides, side opens the door 4 between described underframe 4, top beam of laterally 3, and it is connected by hinge 5 with corner post 2.
As shown in Figure 3, side is opened the door and 4 is provided with gasket 41, and gasket 41 forms the hermetically-sealed construction of top and both sides respectively with top beam of laterally 3, corner post (not marking among the figure).And side open the door 4 with the sealing of underframe 1, be that the curb girder 11 by underframe 1 is provided with sealing band 10, sealing band 10 is resisted against the open the door medial surface B of 4 door crossbeam 40 of side and goes up and form the bottom hermetically-sealed construction, and the open the door medial surface B of 4 door crossbeam 40 of side is a sealing surface.Sealing band 10 cross sections on the underframe 1 are the solid squares vertical bar, also can be square hollow vertical bar and circular vertical bar uniform cross section structure, and its length equates substantially with curb girder 11 length of underframe 1.
In case side opening door freight container is behind lade, the curb girder 11 on the underframe 1 produces and is bent downwardly distortion, and the door crossbeam 40 of the curb girder 11 relative chamber doors 4 on the underframe 1 produces displacement, and the sealing band 10 phase opposite house crossbeams 40 that are installed on the curb girder 11 produce slippage.After the slippage, sealing band 10 still fits tightly the formation sealing surface with the medial surface B of door crossbeam 40.So, can not produce and be bent downwardly distortion, and destroy the sealing property of chamber door 4 and underframe 1 because of the curb girder on the underframe 1 11.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model accompanying Claim.
