The aperture crossed in the middle of it（4）In compartment（9）On, iron chains（2）One end is hinged on flap（1）Front end, the other end is fixed on bearing
（3）On, flap（1）Rear end be fixed on rear railway carriage or compartment（5）On, rear railway carriage or compartment（5）Lower end is welded and fixed axle（7）, support member（6）It is welded on side
On railway carriage or compartment, fixing axle（7）With support member（6）It is engaged.
The beneficial effects of the utility model are：It is simple and reasonable, it is hinged and is hardly damaged, maintenance cost is low, practical.
Brief description of the drawings
Fig. 1 is schematic diagram when the utility model back door closes；
Fig. 2 is schematic diagram when the utility model back door is opened；
In figure：1- flaps, 2- iron chains, 3- bearings, 4- apertures, railway carriage or compartment after 5-, 6- support members, 7- fixing axles, 8- undercarriages, 9- cars
Railway carriage or compartment.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, when compartment 9 is lifted, flap 1 is lifted together with compartment 9, due to the limitation of iron chains 2, flap 1
Can only be rotated around pin joint aperture 4, rear railway carriage or compartment 5 is raised.Fixing axle 7 coordinates with support 6, to reduce the pulling force that iron chains 2 is subject to,
Prevent iron chains 2 from damaging.
