Description

Anti-collision package body for torsion bar transportation Technical Field The utility model belongs to the technical field of transportation packaging, and particularly relates to an anti-collision packaging body for torsion bar transportation. Background The torsion bar is used as a key component of a mechanical transmission system, and the surface spline structure and the middle shaft part of the torsion bar are easy to deform or wear due to collision and vibration in the transportation process. The traditional torsion bar transportation package adopts a simple protection mode that a corrugated box is filled with foam blocks, and has the defects that the fixity of a spline part and a foam contact surface is poor, local stress concentration is easy to cause by axial displacement, the integral buffer structure is single, the multidirectional impact force cannot be dispersed, and the like. Disclosure of utility model The utility model aims to provide an anti-collision package body for torsion bar transportation, which aims to solve the problems of poor fixing effect, insufficient protection effect, single buffer structure and the like of common torsion bar transportation packages. The corrugated paper packaging box comprises a corrugated paper packaging box, wherein a foam box is arranged in the corrugated paper packaging box, the foam box comprises a pair of assembled box bodies, a central shaft groove and spline grooves at two ends of the central shaft groove are formed in the inner sides of the assembled box bodies, the diameter of each spline groove is not smaller than that of the central shaft groove, a sponge sleeve is arranged in each spline groove, the outer diameter of each sponge sleeve is identical to that of each spline groove, rubber plates are inserted into the inner sides of the two ends of the assembled box bodies, the assembled box bodies are fastened through binding belts, and wavy buffer paper cushion layers are filled between the inner walls of the corrugated paper packaging box and the foam box. Further, the inner side of the center shaft groove is fixedly provided with a plurality of axially arranged convex strips, the convex strips are uniformly distributed along the circumferential direction by 10 strips, the section is semicircular, and the height of the convex strips is 2-3mm. Further, the sponge sleeve is formed by sticking a cylindrical sponge and a circular plate-shaped sponge, and the length of the sponge sleeve is the same as that of the spline groove. Further, two sections of hollowed-out parts with larger sizes are arranged at the bottom of the assembled box body, the contact surface between the bottom of the assembled box body and the corrugated paper packing box is divided into three parts, the hollowed-out parts are not arranged right below the spline grooves, the length of each hollowed-out part is 1/2 of the total length of the assembled box body, and the height of each hollowed-out part is 1/3 of the height of the assembled box body. Further, the strapping tape ties up the fretwork position. Further, the rubber plate is located between the outer wall of one end of the assembled box body and the spline groove. The utility model has the beneficial effects that the design is reasonable, and the utility model has the following beneficial effects: 1. According to the scheme, 10 semicircular raised strips circumferentially and uniformly distributed in the center shaft groove limit the axial sliding of the torsion bar by increasing the friction coefficient and matching the lengths of the center shaft groove and the spline groove, and the sponge sleeve flexibly wraps the spline part to form a composite protection system of rigid limit and elastic buffer, so that fretting wear caused by transportation vibration is reduced; 2. In the scheme of the utility model, the two-section foam box reduces the material consumption through the hollow structure with the length of 1/2 of the bottom, reduces the contact area between the foam box and the packaging box, reduces vibration conduction, and avoids the breakage risk of the foam box caused by stress concentration; 3. According to the scheme, the rubber plates are embedded into the inner sides of the two ends of the assembly box body, so that the second protection is provided when the foam box is subjected to a large amount of impact to cause edge breakage, and micro damage caused by direct impact of the spline on the packing box and collision of external objects is avoided.
