Improved fastening screw

Abstract

The invention discloses an improved fastening screw which comprises a screw body. A nut is arranged on the top of the screw body, an inner hexagon hole is formed in the center of the upper surface of the nut, a groove is formed in the center of the bottom of the inner hexagon hole, a gasket which is matched with the groove is arranged in the groove, a main channel is arranged in the center of the bottom of the groove, the bottom of the main channel extends into the screw body, external threads are arranged on the side surfaces of the screw body, a plurality of transverse branches are symmetrically arranged on two sides of the main channel, and the ends of the transverse branches penetrate the external threads. The improved fastening screw has the advantages that the improved fastening screw is novel and reasonable in structure, a mode for rotationally nailing the improved fastening screw and then injecting glue is adopted, accordingly, the improved fastening screw is easy and convenient to operate, good in fastening property, long in service life and particularly suitable to be used in industries with requirements on repeatedly assembling components, and loosening conditions can be effectively prevented.

Description

technical field [0001] The present invention relates to a screw, in particular to an improved fastening screw. Background technique [0002] Various fasteners are used in various fields such as machinery, equipment, vehicles, ships, railways, construction, supplies, etc., and screws are the most common fasteners in the process of workpiece connection, especially in the furniture industry. In order to reduce the difficulty of transportation, the way of directly transporting the parts is usually adopted, and then tightening with screws after reaching the purpose. However, after a long time of use, the furniture is prone to loosening, which makes the re-transportation or installation of the furniture quite difficult, and also affects the furniture. Normal use brings great inconvenience to people's lives. In order to solve this problem, the current practice is to apply glue to the threaded part of the screw before screwing in, so that the screw and the component are tightly con...

AI Technical Summary

Problems solved by technology

In order to reduce the difficulty of transportation, the method of direct transportation of parts is usually used, and then fastened with screws after reaching the destination. However, after a long period of use, the furniture is prone to loosening, which makes it difficult to transport or install the furniture again, and also affects the quality of the furniture. Normal use has brought great inconvenience to people's lives

In order to solve this problem, the current method is to apply glue on the threaded part of the screw before nailing, so that the thread is tightly connected with the parts, but because the screw is driven in by rotation, a large part of the glue overflows, and the fastness of the connection not meet the requirements
