Description

Stainless steel invisible connecting piece for section bar connection Technical Field The invention relates to the technical field of connecting pieces, in particular to a stainless steel invisible connecting piece for section bar connection. Background In a plurality of fields such as industrial manufacture, home decoration, building curtain walls and the like, the section bar is taken as a core bearing and frame member, the connection reliability, the assembly efficiency and the appearance neatness directly determine the performance and the quality of the whole product, along with the popularization of a modularized assembly concept and the continuous improvement of the aesthetic property requirements of consumers on the product, the traditional exposed connecting piece (such as corner connector, bolt, rivet and the like) has difficulty in meeting the requirements of high-end application scenes due to the defects of abrupt appearance, easy collide and scratch, difficult cleaning of accumulated ash and the like, and the invisible connecting piece gradually becomes the main flow development direction of the section bar connecting technology; However, the hole site alignment operation is difficult when the existing stainless steel invisible connecting piece is installed, because the connecting piece is in an invisible design, the connecting point is positioned in the section bar during assembly or in a hidden position, an operator cannot intuitively observe the hole site alignment state, and in addition, most connecting pieces are not provided with a guiding and positioning structure and are aligned only by experience or an auxiliary measuring tool, so that the situation that a screw hole is misplaced with a connecting piece installation hole is very easy to occur, the position of the section bar is required to be repeatedly adjusted, a large amount of assembly time is consumed, and the screw thread damage and the section bar deformation are caused due to forced alignment in severe cases, so that the fittings and the section bar are scrapped.
