Description

A connecting piece for the side wall of a large box and a box with the connecting piece

technical field

The utility model relates to a large-scale box body structure for loading goods, in particular to a connector for the side wall of a large-scale box body and a box body with the connector.

Background technique

Large boxes are widely used in the storage and transportation of goods, such as container boxes, van semi-trailer compartments, van compartments, etc. The side wall structure of large boxes needs to meet the strength requirements for storing and transporting goods, so higher requirements are put forward for the side wall structure.

For example, the side wall of a traditional van-type semi-trailer body is composed of a skeleton structure plus an inner and outer skin (steel plate or aluminum plate) to form a side plate, and the side plates are riveted to form the side wall. Large, heavy weight, difficult to maintain, and the width of the box is limited, so the side wall of this skeleton structure has gradually faded out of the market. At present, the side wall of the van-type semi-trailer mainly adopts side panels without a skeleton structure, such as composite panels composed of metal surface panels and multi-layer plywood, wood panels, plastic panels or other wood-based panels. The surface metal plate of the composite board is bonded to the core board by an adhesive. Because the inner and outer surfaces of this composite board are relatively smooth, the car body is more beautiful.

As shown in Figure 1, the length of a general van-type semi-trailer body is about 16m, which requires 13 composite panels 10 with a width of about 1m to be vertically spliced together to form a side wall, as shown in Figure 2, adjacent composite panels 10 are connected by the inner connector 11, the outer connector 12 and the rivet 13, so that the connected side wall meets the strength and rigidity requirements of the van semi-trailer body. The side wall structure of the existing van-type semi-trailer requires 12 pairs of inner and outer connectors. The length of each pair of inner and outer connectors is about 2.6m, and the total length of the required inner and outer connectors is about 31m. The material consumption of the connecting parts is relatively high. In addition, as shown in FIG. 2 , since the inner and outer connectors are vertically connected to the composite panel, the inner connector 11 and the outer connector 12 are overlapped on the composite panel 10, so that the inner connector 11 protrudes from the surface of the composite panel 10, When the cargo is loaded and unloaded, it is easy to scratch or get stuck with the inner connector 11 , causing damage to the cargo and the inner connector 11 .

In order to solve the above-mentioned defects that the material consumption of the connecting parts is large and the inner connecting parts are easy to scratch the goods, the composite board is divided into upper and lower parts, and the upper and lower parts of the composite board are connected by a horizontal connecting part parallel to the length direction of the car body. The side wall connection structure, but the side wall connection structure has the following defects: when the water on the outside of the car body penetrates between the inner and outer connectors along the side wall, it is easy to seep into the inside of the car body, causing the goods in the car body to be damaged by moisture.
