Connecting screw

Abstract

The invention discloses a connecting screw, and belongs to the field of cargo packing. The connecting screw comprises a nut, a hexagonal screw, a toothed meson, a clamp spring meson and a pit meson, wherein the nut and the hexagonal screw are matched together; the toothed meson is assembled with the lower end of the nut together; the clamp spring meson is clamped on the nut; the pit meson is matched with the hexagonal screw together; the toothed meson is provided with 2 to 6 teeth and 2 to 6 mounting holes; the inner wall of the central hole of the toothed meson is provided with 2 to 6 lugs; and the clamp spring meson is provided with a plurality of trapezoidal clamping teeth. The connecting screw is used for sewing a paperboard packing box, has firm connection and high sewing speed, and is convenient to assemble and disassemble; the sewn product is attractive and high in quality; the connecting screw can relieve the labor intensity of workers, improve the work efficiency, reduce the labor amount, reduce the production cost of enterprises and improve the economic benefit, and is favorable for environmental protection; and the sewing process for the paperboard packing box produces epoch-making revolutionary change, and brings new vigor and vitality to the packing industry.

Description

technical field [0001] The invention relates to the field of cargo packaging, in particular to a connecting screw. Background technique [0002] In the field of cargo packaging, the packaging boxes used for packaging goods are made of cardboard. Packaging boxes made of cardboard are stitched with adhesive or copper nails during the manufacturing process. The cardboard packaging box is sewn by applying adhesive or copper nails, the labor intensity of the workers is high, and the work efficiency is low; the quality of the stitched cardboard packaging box is not high, and the appearance is not beautiful; the production cost of the enterprise is high. With the advancement of science and technology and the continuous development of society, the way of sewing cardboard boxes needs to be updated. Therefore, people are eager to reduce the labor intensity of workers, improve the work efficiency and the quality of the cardboard packaging box stitched, reduce the production cost of t...
