The specific embodiment

As shown in Figure 1, a kind of freight container 10 of the present utility model comprises: a underframe 11; Be fixed on two side plates 12 on the underframe 11; Be fixed on door end 13 and front wall 14 on the underframe 11, utilize two side plates of column 16 and this 12 fixing simultaneously, wherein door end 13 is provided with a chamber door 17 and a latching device 20.

Specifically, latching device 20 at first comprises a connecting rod mechanism 21 that is arranged on the side plate 12.As shown in Figure 2, connecting rod mechanism 21 is for preferably being parallel linkage, and wherein relative first parallel bar 214 and second parallel bar 215 are arranged vertically, and utilize the 3rd relative parallel bar 211 and the 4th parallel bar 213 to be fixed to this side plate 12.Preferably, the utility model also is provided with the 5th an auxiliary parallel bar 212 especially, between this third and fourth

parallel bar

211 and 213 to strengthen intensity.Can utilize the connecting

element

2111,2121 and 2131 that is arranged on general headquarters that connecting rod mechanism 21 is fixed respectively.Simultaneously, also be fixed with on the side plate and the 3rd, the 4th and the 5th parallel bar 211,212 and 213 cooresponding guide grooves 251,252 and 253, and guide groove can be respectively fixed to column 16.233 the end of cranking arm on described the 4th parallel bar 213 connects one handle 22, like this have need in, operating personal just can carry out M/C easily on ground.

231,232 and 233 the end of cranking arm can utilize

hinge

2112,2122 and 2132 to be rotatably connected on the 3rd to the 5th parallel bar 211,212 and 213 of this connecting rod mechanism, and the other end is defined along this guide groove 251,252 and 253 and slides.More particularly, this end that is limited in the guide groove that this is cranked arm also is rotationally connected with hook 241,242 and 243 respectively by

hinge

2311,2321 and 2331.At last, this hook 241,242 and 243 cooperates with the rod member 18 that stretches out from chamber door respectively.

In conjunction with Fig. 1 and Fig. 2, freight container 10 of the present utility model also comprises a pushing mechanism 30, has first power rail 31, aims at this first parallel bar 214 and second power rail 32, aims at this second parallel bar 215 and is provided with.Certainly, pushing mechanism 30 of the present utility model can also alignment handle 22 be provided with, as shown in Figure 4.Power rail is hydraulic stem or atmospheric pressure pole or electric rod.
