Abstract

The invention discloses a semitrailer external crossing door structure, which comprises a vehicle door and a vehicle bottom assembly, wherein the vehicle bottom assembly consists of a side beam, a side supporter and a bottom plate, the vehicle door is hinged with the side beam through a hinging element, and the inner side surface of the vehicle door is overlapped with the outer end surface of the side beam when the vehicle door is closed. In the semitrailer external crossing door structure, the inner side surface of the vehicle door is overlapped with the outer end surface of the side beam when the vehicle door is closed, the vehicle door spans over the side beam through the hinging element, the actual carriage width is the vehicle bottom width, the carriage volume is effectively increased on the premise of the same vehicle bottom width, and the cargo carrying capacity of a semitrailer can be increased.

Description

Superimposed trailer is striden door outward

Technical field

The invention belongs to the superimposed trailer field, relate in particular to a kind of superimposed trailer and stride door outward.

Background technology

Width at the bottom of the superimposed trailer car is generally fixed, and during closing of the door, the door outside face overlaps with the car bottom side; The width in compartment is the width that the width at the bottom of the car deducts the both sides car door; The shortcoming of this structure design is that carriage box volume capacity is little, has reduced the cargo capacity of superimposed trailer.

Summary of the invention

The purpose of this invention is to provide the big superimposed trailer of a kind of carriage box volume capacity and stride door outward.

For achieving the above object, the technical scheme that the present invention adopts is:

Superimposed trailer is striden door outward, comprise car door and the car formed by side bar, temple and base plate at the bottom of assembly, car door and side bar are hinged through articulation piece, door inner overlaps with the side bar outer face during closing of the door.

Said articulation piece comprises fixed end and movable end, and fixed end is connected through axle with movable end; Said fixed end end is connected with side bar, and movable end is inboard to be connected with the door outside face.

Said base plate is the bamboo offset plate.

Among the present invention, door inner overlaps with the side bar outer face during closing of the door, and car door is passed through articulation piece on side bar, and actual box width is car bottom width degree, same car bottom width degree, and actv. increases carriage box volume capacity, can increase the cargo capacity of superimposed trailer.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is an articulation piece structural representation among the present invention.

The specific embodiment

Like Fig. 1, shown in Figure 2, superimposed trailer is striden door outward, comprise car door 1 and the car formed by side bar 4, temple 3 and base plate 2 at the bottom of assembly, car door 1 is hinged through articulation piece 5 with side bar 4, car door 1 medial surface overlapped with side bar 4 outer faces when car door 1 was closed.Said articulation piece 5 comprises fixed end 51 and movable end 53, and fixed end 51 is connected through axle 52 with movable end 53; 4 welding of the end of said fixed end 51 and side bar, the inboard of movable end 53 and the welding of door outside face, base plate adopts the bamboo offset plate, can reduce weight at the bottom of the car, raising superimposed trailer cargo capacity.

Claims

1. superimposed trailer is striden door outward, comprise car door and the car formed by side bar, temple and base plate at the bottom of assembly, it is characterized in that car door and side bar are hinged through articulation piece, door inner overlaps with the side bar outer face during closing of the door.

2. superimposed trailer as claimed in claim 1 is striden door outward, it is characterized in that, said articulation piece comprises fixed end and movable end, and fixed end is connected through axle with movable end; Said fixed end end is connected with side bar, and movable end is inboard to be connected with the door outside face.

3. according to claim 1 or claim 2 superimposed trailer is striden door outward, it is characterized in that said base plate is the bamboo offset plate.
