Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the schematic appearance after the utility model is installed.
Accompanying drawing 3 is the structural representations on the utility model door limit.
Accompanying drawing 4 is left views of accompanying drawing 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Carriage back door plate of the present utility model 1 left and right sides and connecting lever 2 connect as one, connecting lever 2 is hinged with the supporting base 4 that both sides, compartment rear column 3 is fixed, the hinged place of connecting lever 2 and supporting base 4 is the draw-in groove under shed, and supporting base 4 is to be stuck in to constitute connecting lever 2 and supporting base 4 pivotally attached structures in the draw-in groove.
The both sides of described rear column 3 are fixed with fixture block 7, and the corresponding position, both sides of described Rear Door 1 is fixed with block 8, and described block 8 is in the upper end of fixture block 7 when Rear Door 1 is closed.
In the present embodiment, its bottom land of the draw-in groove on the described connecting lever is the draw-in groove of circular arc; The opening of the draw-in groove on the described connecting lever is tubaeform.
Concrete manufacturing process is:
Carriage of dump truck Rear Door 1 left and right sides is welded into one with connecting lever 2, and the upper end of connecting lever is drilled with a garden shaped pin hole, and mills out a up-small and down-big exit skirt along garden shaped pin hole downward direction; Be welded with supporting base 4 on both sides, the compartment rear column 3, supporting base is installed with bearing pin 5, and bearing pin is terminal with spring cotter 6 lockings.Monoblock carriage back door plate is the exit skirt from the connecting lever 2 just, is directly hung on the bearing pin 5 of supporting base, so Rear Door can rotate around bearing pin, thereby realizes the opening and closing action at back door.
In addition, fixture block 7 is welded on the compartment rear column, and block 8 is welded on the Rear Door, leaves 1 ~ 2 millimeter gap between fixture block 7 and the block 8.Because fixture block 7 and baffle plate jam about in the of 8, so, when automotive operation, can prevent Rear Door play up and down.
