Description

Movable bumper for semitrailer

Technical Field

The utility model relates to a bumper installation technical field especially relates to a movable bumper for semitrailer.

Background

With the increasing activity of goods trade, the transportation industry is also developed and grown, and the development of bulk goods transportation and container transportation is most prominent, thereby promoting the development of trailer-related industries. Semitrailers have become more and more widely used as a tractor for cargo with high load capacity.

At present, semi-trailers are various in types, operation areas are complex and changeable, and users often encounter the situation that stones exist in a construction site or a certain complex regions encounter insufficient departure angles, so that a vehicle body and the stones or the gradient are rubbed, and a chassis is damaged.

The existing semitrailer rear bumper is generally directly welded with a frame girder, and the position is fixed, so that the departure angle cannot be increased by adjusting the height due to road conditions.

Therefore, there is a need to provide a new movable bumper for a semitrailer to solve the above technical problems.

An object of the utility model is to provide a movable bumper for semitrailer, including fixed bolster, movable support and bumper, the quantity of fixed bolster and movable support is two, and the interval sets up about being, be provided with a plurality of jacks on the fixed bolster, movable support one end through a fixed pin with jack connection, two the movable support other end set firmly in the bumper, it is a plurality of the jack is V-arrangement transmission and distributes.

Preferably, the cross section of the fixed support is a C-shaped bending groove, the two side walls are provided with the insertion holes, and the V-shaped corners are arranged at the corners below the side walls of the fixed support and are distributed along the corners in a launching manner.

Preferably, the V-shaped emission distribution structures are four in the vertical direction and three in the horizontal direction, and share one corner hole.

Preferably, the movable support is a bending plate, and a 45-degree chamfer is arranged at an upper corner contacted with the fixed support.

Preferably, the overall dimension of the movable support is smaller than that of the fixed support, and the movable support is sleeved in the C-shaped cavity of the fixed support and is inserted into the corresponding jack through the fixing pin.

Preferably, the license plate fixing device further comprises a license plate mounting plate, wherein the license plate mounting plate is connected to the inner sides of the two fixed brackets and has a gap with the two movable brackets.

Preferably, the license plate mounting plate has an L-shaped or C-shaped bending groove in cross section, and the bending arm is connected to the bumper.

Compared with the prior art, the utility model provides a movable bumper for semitrailer has following beneficial effect:

firstly, the movable support and the fixed support are connected in a jack and fixed pin mode, the angle and height of the bumper can be adjusted quickly, the structure is simple, the processing is easy, and the adjustment is more convenient;

two, through the setting of fixed bolster jack, can realize rotating or lift two kinds of adjustment modes, can satisfy multiple type semitrailer demand, the universalization degree is high, convenient to use.
