Tail lamp folding bracket of dump truck

Abstract

The invention belongs to the field of automobile accessories, and relates to a tail lamp folding bracket of a dump truck, which is characterized in that cylindrical rotating shafts are longitudinally installed on the two sides of the lower portion of the tail of a rectangular container through D-shaped supports respectively, concave supports are installed in the middles of the rotating shafts, and rectangular tail lamp supports are installed below the concave supports; a spiral return spring is installed in the center of the rotating shaft, an L-shaped baffle is installed on the right side of the concave support, two disc-shaped riding wheels are transversely installed below the container on the left side of the rotating shaft through a rectangular support, and the lower portion of the taillight support penetrates through the two riding wheels through a round steel wire rope to be connected with an extension spring in the middle of the right side of the girder. When the dump truck dumps silt, the oil cylinder slowly lifts the cargo tank, the distance between the cargo tank and the girder is slowly increased, the riding wheel pulls the steel wire rope upwards, and the steel wire rope synchronously and slowly flattens the taillight support forwards to be hidden below the tail of the lifted cargo tank so as to prevent the taillight support from being collided and stained by the silt.

Description

technical field [0001] The invention relates to a rear tail light folding bracket of a dump truck, which belongs to the field of auto parts, and in particular relates to a foldable and hidden rear tail light of a dump truck when dumping goods. Background technique [0002] A dump truck is a truck in which the cargo box is lifted and tilted by an oil cylinder and the cargo is unloaded by itself. Most dump trucks are used to carry sand and gravel. When unloading sand and gravel, the oil cylinder under the truck frame needs to lift the sub-beam and the cargo box backwards and tilt > 45°, and the sand and gravel slide from the rear of the cargo box by its own weight. to the ground. The rear taillights of existing dump trucks are all installed under the tail of the cargo box, and there is still a hard link between the taillight bracket and the beam. It often adheres to the inner wall of the container and is difficult to fall off by itself. To save trouble, some drivers will ...

AI Technical Summary

Problems solved by technology

The rear taillights of existing dump trucks are all installed under the tail of the cargo box, and there is still a hard link between the taillight bracket and the beam. It often adheres to the inner wall of the container and is difficult to fall off by itself. To save trouble, some drivers will hold the container high to move the dump truck back and forth quickly in place, and rely on the reaction force to shake off the sand and mud on the inner wall of the container. However, when the dump truck is moving back and forth, the tail of the container and the rear of the beam often continuously collide with the sand and soil dumped on the ground. Because most of the tail lights of the dump truck are connected to the tail of the beam, and the tail lights are all Made of plastic, it is easy to be damaged or seriously defaced by sand and mud, and the driver continues to drive on the road without the driver's knowledge. send
