The invention relates to a fast-installation expansion screw. The fast-installation expansion screw comprises an expansion body similar to a rugby body, a thread line, a nail head sleeve barrel and a small hole; the expansion body similar to the rugby body and thread line are connected and combined on the nail head sleeve barrel, and the other end of the thread line passes through a small hole in the side of the lower edge of a nail head cap of the nail head sleeve barrel. The thread line is used for connecting and tightening the sleeve port of the nail head sleeve barrel provided with a plurality of nick grooves with the expansion body similar to the rugby body, when knocking on the nail head cap of the nail head sleeve barrel in the construction, the expansion body similar to the rugby body is convenient to be embedded, meshed and fastened in the nick groove port of the nail head sleeve barrel provided with a plurality of nick grooves; the thread line passes through the small hole in the side of the lower edge of the nail head cap of the nail head sleeve barrel to facilitate connecting, winding, binding, hoisting and tightening an external object to be connected. The fast-installation expansion screw has advantages of simple manufacturing technique, material saving, fast and convenient mounting, high working efficiency and the like.
Description
technical field [0001] The invention relates to an expansion screw, in particular to an expansion screw for quick installation, which has the functions of pulling, hanging, supporting and connecting external objects, and is suitable for use in concrete, stone, brick, hard wood, clinker brick, hard synthetic Materials and metals and other close-structured wall, floor, column, ground and other installations are applied. Background technique [0002] At present, all expansion screws on the market are locked and fixed by threaded core rod and nut. This structure has the disadvantages of large amount of material, time-consuming operation, labor-intensive, low work efficiency, and the middle screw and its locked nut. The deficiencies such as complicated process and high cost. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a quick-install expansion screw. Using an expansion body similar to a footb...
