Description

Tailless thread sleeve convenient to install

Technical Field

The utility model relates to the technical field of hardware fasteners, in particular to a tailless threaded sleeve convenient to install.

Background

It is known that the threaded sleeve is also called a steel wire threaded sleeve, is an internal threaded fastener convenient to install, is suitable for threaded connection, is screwed into and fastened in a threaded hole of one of the connected pieces to form a standard internal thread, is a spring-shaped internal and external threaded concentric body of a tailless threaded sleeve which is formed by precisely processing a cold-rolled diamond stainless steel wire with high strength, high precision and smooth surface, and is mainly used for reinforcing and protecting the internal thread of a low-strength material. The principle is that elastic connection is formed between the screw and the internal thread of the matrix, thereby eliminating the manufacturing error of the thread and improving the connection strength.

The threaded sleeve is embedded into threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic and plastic, can form high-precision internal threads meeting international standards, has the functions of high connection strength, shock resistance, impact resistance and wear resistance, can disperse stress to protect threads of a matrix, greatly prolongs the service life of the matrix, and is widely applied to electronic applications. For example: the Chinese patent No. 202122157546.6 discloses a steel wire thread sleeve with a guiding function, but the installation efficiency of the thread sleeve is low, the fracture of the installation handle of the thread sleeve cannot be controlled well, the installation handle is difficult to break or is excessively easy to break, when the handle is removed, the tail end of the thread sleeve is easy to protrude, burrs are formed, the subsequent screw thread screwing in is affected, the product quality is seriously affected, the installation handle is remained in the installation hole after being removed, the installation handle is difficult to clean, the retention in the installation hole is easy to cause, and the quality of the whole product is seriously affected. Meanwhile, the production efficiency is seriously affected when the traditional thread bush is installed and removed, the installation speed is low, the thread bush is installed in a hole, and when a user needs to detach, the thread bush can not be detached almost due to the fact that the stress point is arranged in the thread bush, so that the maintenance and the replacement of the thread bush are inconvenient for the user; meanwhile, the existing thread bush is large in gap after being installed, the existing thread bush is easy to loosen and fall off after vibrating for a long time, and the installed bolt can fall off when severe. The above drawbacks are therefore evident, and we propose a tailless thread bush which is easy to install for solving the above problems.
