Description

Installation fastening external member and installation fastening assembly

Technical Field

The utility model relates to the technical field of electronic and communication equipment, in particular to a mounting and fastening kit and a mounting and fastening assembly.

Background

The installation scene of the equipment comprises panel type installation and wall installation. For a panel installation scene, many panel materials are not suitable for tapping threads, and the tapping screws are easy to lose efficacy after being disassembled and assembled for many times. The existing panel installation fasteners in the market have requirements on plate thickness, and one fastener cannot adapt to installation scenes of different plate thicknesses. For the wall installation scene, the wall can not be tapped, and an expansion bolt is usually used for firstly embedding the wall and then tightening a nut for fastening, so that the wall installation is different from a panel installation fastener, and the wall installation can not be considered.

The common expansion bolt in the prior art is only suitable for wall installation, and a spanner is required to screw a nut, so that the spanner operation has certain requirements on an operation space. Petal expansion bolts and aircraft expansion bolts are only suitable for panel installation, and bolts with corresponding thickness specifications are required to be selected for panels with each thickness. Chinese patent publication No. CN110005060a discloses a wood-structured steel tenon connecting piece, which is only suitable for connecting two wooden pieces, but cannot be used for panel installation and wall-mounted installation.
