Description
Technical field
The utility model relates to a kind of power supply box of carriage air conditioner inverter, particularly relates to a kind of door-plate anti-drop device of carriage air conditioner inverter power supply case.
Background technology
If railroad coach supply unit is in operation, electrochemical capacitor is blasted, to produce powerful impulsive force, under car, hang casing door-plate and can fly out because powerful impulsive force comes off, thereby the safe operation of railroad coach and driver and conductor's personal safety is constituted a serious threat.
Existing air-conditioning inverter power supply box comprises casing and is arranged on the door-plate on casing, door-plate anti-drop device comprises hanging and hook, described hanging is weldingly fixed on casing, described welding hook is fixed on door-plate, described hanging is inverted U, the groove that is provided with perforation at the top of hanging, described hook is tabular and is provided with the through hole running through, and the plate body on the through hole top of hook is inlaid in the groove of hanging.The door-plate anti-drop device of this structure, when the electric device of box house is blasted the powerful impulsive force of generation, due to door-plate can be up after stressed play, make the hook on door-plate depart from the hanging on casing, cause door-plate to come off, so the anticreep poor-performing of this anti-drop device, serious threat traffic safety.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can effectively prevents that casing door-plate from coming off when being subject to powerful impulsive force, guarantees the carriage air conditioner inverter power supply box door plate anti-drop device of traffic safety.
For solving the problems of the technologies described above, the utility model adopts a kind of like this carriage air conditioner inverter power supply box door plate anti-drop device, described air-conditioning inverter power supply box comprises casing and is arranged on the door-plate on casing, described door-plate anti-drop device comprises hanging and hook, described hanging is fixedly mounted on casing, described hook is fixedly mounted on door-plate, described hanging is inverted U, at the top of hanging, be provided with the groove of perforation, described hook is tabular and is provided with the through hole running through, the plate body on the through hole top of hook is inlaid in the groove of hanging, plate on the through hole top of described hook is in the flap that is also provided with an outside bending.
In the utility model, the flap along continuous straight runs that described hook through hole upper board is in stretches out.
Adopt after said structure, the utlity model has following beneficial effect:
The utility model is in after the flap that an outside bending is set at the plate on the through hole top of hook, when the electric device of box house is blasted the powerful impulsive force of generation, door-plate is stressed being extremely restricted vertically upward, make that door-plate is stressed cannot depart from the hanging on casing up time, thereby effectively prevented that door-plate from coming off when being subject to powerful impulsive force, guaranteed traffic safety.

Embodiment
Referring to a kind of carriage air conditioner inverter power supply box door plate anti-drop device shown in Fig. 1 to Fig. 6, described air-conditioning inverter power supply box comprises casing 1 and is arranged on the door-plate 2 on casing 1, described door-plate anti-drop device comprises hanging 3 and hook 4, described hanging 3 is arranged on casing 1 by being welded and fixed, described hook 4 is arranged on door-plate 2 by being welded and fixed, described hanging 3 is inverted U, at the top of hanging 3, be provided with the groove 3-1 of perforation, described hook 4 is tabular and is provided with the through hole 4-1 running through, when mounted, the plate body 4-2 on the through hole 4-1 top of hook 4 is inlaid in the groove 3-1 of hanging 3, at the plate body 4-2 place on the through hole 4-1 top of described hook 4, be also provided with the flap 4-2-1 of an outside bending.
In the utility model, as shown in Figure 2,3, the flap 4-2-1 along continuous straight runs at described hook through hole 4-1 upper board body 4-2 place stretches out.
In the utility model, the single piece that described flap 4-2-1 is preferably made into integration with plate body 4-2, certainly, described flap 4-2-1 also can be arranged on plate body 4-2 by welding or other fixed form.
As shown in Figure 1, when casing 1 internal electrical device may be blasted, the door-plate 2 being arranged on casing 1 will be severely affected power, but because door-plate 2 has been subject to very big restriction at vertically upward stressed, door-plate 2 cannot depart from the hanging 3 on casing 1, thereby effectively prevented that door-plate 2 from coming off when being subject to powerful impulsive force, reached the effect that prevents that door-plate from coming off, guaranteed traffic safety.
