Description

Circulation transport case with shock attenuation supports Technical Field The utility model relates to the technical field of logistics transportation equipment, in particular to a circulating transportation box with a damping support. Background With the continuous development of the logistics transportation industry, the demand for environment-friendly, efficient and recyclable packaging containers is increasing. EPP (expanded polypropylene) is widely applied to manufacturing of transport cases as a high-performance environment-friendly material due to the characteristics of light weight, excellent pressure resistance, excellent buffering performance and the like. At present, a plurality of circulating transport boxes made of EPP materials exist on the market, and the circulating transport boxes are widely used for the goods turnover transport in the fields of foods, medicines, electronics, automobile parts and the like. The existing circulating transport case still has certain defects in the actual use process, as most transport cases are not provided with special damping support structures, when the transport cases encounter vibration or impact in the transport process, internal articles are easy to displace or even damage, particularly when the transport cases are stacked and placed, an effective buffer connection mechanism is lacked between the upper case body and the lower case body, so that vibration can be directly transmitted into the lower case body, the transport safety is affected, in addition, in order to make up the structural defects, the additional addition of foam pads, air bags and other disposable buffer materials is usually required, the recycling efficiency of the transport cases is reduced, and the packaging cost and the environmental burden are increased. Disclosure of utility model The utility model aims to provide a circulating transport case with a damping support, so as to solve the problems that the conventional circulating transport case provided by the background art lacks an effective damping structure, has obvious vibration conduction during stacking and depends on additional buffering materials. In order to achieve the purpose, the circulating transport case with the shock absorption support comprises a transport case main body, wherein an upper end connecting frame and a lower end supporting frame are respectively arranged at the top and the bottom of the transport case main body, strip-shaped bearing bosses are symmetrically arranged on the long side of the upper end connecting frame, a plurality of modularized shock absorption units are arranged at intervals along the length direction at the top of the strip-shaped bearing bosses, supporting caulking grooves matched with the strip-shaped bearing bosses are symmetrically arranged on the long side of the lower end supporting frame, notches are formed in four corners of the upper end connecting frame and the lower end supporting frame, and connecting pieces are rotatably connected in the notches. Preferably, the inside of the connecting piece is penetrated with a connecting shaft through a through hole, one corresponding end of each group of the connecting shaft is connected through a thread structure, and an elastic supporting ring is sleeved outside the connecting end of the connecting shaft. Preferably, the four corners at the top of the upper end connecting frame are provided with trapezoidal protruding blocks, and the four corners at the bottom of the lower end supporting frame are provided with trapezoidal caulking grooves matched with the trapezoidal protruding block in structure. Preferably, a spiral ring is welded and fixed on the side outer wall of the connecting piece, a positioning bolt is inserted in the spiral ring through a thread structure, and a positioning screw hole matched with the positioning bolt structure is formed in the side inner wall of the notch. Preferably, the upper end connecting frame and the lower end supporting frame are made of an integrated molding with the transport case main body, and the widths of the upper end connecting frame and the lower end supporting frame are larger than the outline of the outer wall of the transport case main body. Preferably, support ribs are arranged on the periphery of the inner wall of the transport case main body, and the support ribs are arranged in a wavy extending mode and adopt an EPP integrated structure. Compared with the prior art, the circulating transport case with the shock absorption support has the beneficial effects that good shock absorption protection is realized, the transport stability and the safety are improved, meanwhile, the dependence on additional buffer materials is reduced, and the recycling efficiency is improved. This circulation transport case with shock attenuation supports combines the spacing design of bar bearing boss and bearing caulking groove through the cooperation structure of upper end connecting frame and lower extre
