In order to solve the problems, the technical scheme adopted by the invention is as follows:
the utility model provides a freight train is with multi-functional step footboard, includes the main tributary dagger, the welding has the horizontal connecting rod in the middle of the main tributary dagger, the welding has first footboard main tributary dagger top, the welding has the second footboard main tributary dagger below, second footboard lower surface is connected with the third footboard, third footboard upper surface both ends all are hinged and are connected with swing joint board one, second footboard lower surface both ends position all is hinged and is connected with swing joint board two, through the mode interconnect of hinged joint between swing joint board one and the swing joint board two, and the junction is equipped with the convolution spring, swing joint board one and swing joint board two are folding under the effect of convolution spring, upwards draw the third footboard.
Furthermore, one side that third footboard and main tributary dagger are adjacent is equipped with the extension board, be fixed with telescopic machanism on the main tributary dagger, telescopic machanism flexible end is down and the top is on the extension board.
Further, the telescopic mechanism is an electric cylinder which is vertically installed.
Further, the telescopic mechanism is fixed in the main support column.
Further, the first movable connecting plate and the second movable connecting plate are folded towards the middle position of the second pedal under the action of the convolution spring.
Further, first footboard and second footboard structure are unanimous, all include pedal part and coupling part, pedal part is the rectangle structure, the coupling part is isosceles trapezoid structure, isosceles trapezoid structure base aligns and interconnect with the long limit of rectangle structure.
Further, the third pedal comprises a pedal part and a connecting part, wherein the pedal part and the connecting part are both of rectangular structures and have the same length, and the long sides of the pedal part and the connecting part are aligned and connected with each other.
Compared with the prior art, the invention has the following beneficial effects:
the invention relates to a multifunctional step pedal for a truck, which adopts a three-layer step pedal, wherein a first pedal and a second pedal adopt a fixed structure, a third pedal is fixed through a first movable connecting plate and a second movable connecting plate, the third pedal retracts below the second pedal under the action of a convolution spring under the condition that the third pedal is not subjected to external force, and the third pedal extends downwards under the action of the external force when in use, so that the third pedal only needs to be positioned above a tire in a retracting state, extends when in use, retracts when in use, not only the up and down of personnel are improved, but also the safety risk is reduced.
