Novel connection device for right-angle turn of thick board

Abstract

The invention relates to the field of packaging, in particular to a novel connection device for the right-angle turn of a thick board. The problem of high difficulty in connection between a connectingdevice and the thick board in the prior art is solved mainly, and the novel connection device comprises a first angle bead connecting piece and a second angle bead connecting piece which are wrappedon the parts, close to each other, of two adjacent thick boards separately; the contact areas or the areas, close to each other, on the first angle bead connecting piece and the second angle bead connecting piece are connected through adhesive or sewing or connecting pieces, and the connection area forms a rotating shaft, so that the two thick boards are rotated along the rotating shaft separately, and the sides, located on the same side as the rotating shaft, of the first angle bead connecting piece and the second angle bead connecting piece are defined as the inner side faces; and connectingplates are connected with the inner side faces of the first angle bead connecting piece and the second angle bead connecting piece through adhesive, and first bent lines are arranged at the positions, located on the rotating shaft, of the connecting plates.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a new splicing device for cardboard turning at right angles. Background technique [0002] Cartons are generally used for product packaging, so that fragile and touchable items can be fixed in the box to prevent product damage and deformation, and can withstand various shocks, vibrations, bumps, and compressions during loading, transportation, and storage. , friction and other external forces, forming a protection for the built-in products, with a certain vibration resistance. [0003] The applicant disclosed a right-angle turning connecting device for thick cardboard on the application date: January 3, 2020, and the patent application number: 202010005097.0. The first snap-in slot and the second snap-in slot are snapped together so that the first corner connector and the second corner connector are connected, and two adjacent thick cardboards are respectively inserted into the first sl...
