Connecting element for plate connection

Abstract

A connecting element for plate connection comprises a sleeve tube (100) with a T head and a sleeve rod (200) with a T head. The sleeve rod (200) is inserted in the sleeve tube (100) and is engaged with the sleeve tube (100) so that the connecting element forms an I shape. A front end of the sleeve rod (200) is provided with an engagement portion (220). An engagement matching portion (120) matched with the engagement portion (220) of the sleeve rod (200) is arranged on a tube wall of the sleeve tube (100). The sleeve rod (200) is provided with a center hole (230) penetrating along an axis line. In addition, a plurality of axial grooves (240) capable of radially deforming the front end of the sleeve rod (200) is arranged on the sleeve rod (200). The connecting element further comprises an inserting rod (300). The inserting rod (300) is axially assembled in the center hole (230) of the sleeve rod (200). The inserting rod (300) is assembled in the center hole (230) of the sleeve rod (200), which can prevent radial deformation of the front end of the sleeve rod (200). The engagement structure between the sleeve rod (200) and the sleeve tube (100) is tightly locked, which can prevent loosening of the engagement structure between the sleeve rod (200) and the sleeve tube (100). The connecting element is simple in structure, fast in assembly, and firm in joint.

Description

technical field [0001] The invention relates to a connecting piece for connecting plates. Background technique [0002] The boards used for cargo packaging need to be stitched and fixed by connectors. The traditional connection methods include nailing, gluing and buckling. With the deepening of the concept of energy saving and environmental protection, more and more cardboard boxes are used in the field of goods packaging. In the traditional manufacturing process of cardboard boxes, the cardboards are stitched and fixed by adhesives or copper-plated iron nails. Using these traditional stitching methods, the labor intensity of the workers is relatively high, and the efficiency is not high, and the appearance of the packaging box made is low, and it is easy to break and crack. Especially in the manufacture of packaging boxes for large or super-large equipment, due to the large volume of the box, this kind of box sewn by adhesive or copper-plated iron nails cannot meet the req...

Problems solved by technology

Using these traditional sewing and fixing methods, the labor intensity of the workers is high and the efficiency is not high, and the appearance of the packaging boxes made is low, easy to break and crack

Especially in the manufacture of packaging boxes for large or super-large equipment, due to the large volume of the box, this kind of box sewn by adhesive or copper-plated iron nails cannot meet the requirements of use due to the weak connection, which has become a constraint for large packaging boxes. development bottleneck
