Description

Technical Field

[0001] The utility model relates to the technical field of wire thread inserts, in particular to a wire thread insert that is easy to install. Background Art

[0002] Wire thread inserts are a new type of internal thread fastener suitable for threaded connections. They are screwed into and tightened in the threaded hole of one of the connected parts to form a standard internal thread, into which the bolt (or screw) is then screwed. They are also called threaded wire inserts. They are a spring-shaped concentric body of internal and external threads made of high-strength, high-precision, smooth-surfaced cold-rolled diamond-shaped stainless steel wire, and are mainly used to enhance and protect internal threads made of low-strength materials. The principle is to form an elastic connection between the screw and the internal thread of the base, eliminate thread manufacturing errors, and improve connection strength. After installation, the existing wire thread inserts need to use an external force to cut off the installation handle from one end of the guide, which is more troublesome to install. At the same time, when the installation handle is cut off, it is easy to cause the wire thread insert to loosen, affecting subsequent use.

[0003] For example, an anti-falling wire screw insert with publication number CN220600204U relates to the technical field of wire screw inserts, including a wire screw body, the wire screw body is in the shape of a spirally wound stacked column, the outer sides of the wire screw body are movably connected with an anti-falling structure, the top end of the anti-falling structure is fixedly connected with a connector, and one end of the connector is movably connected with a mounting handle. The utility model squeezes the protrusion through the elasticity of the elastic pad, so that the protrusion fits into the threaded hole in the connector, and the anti-slip strip increases the friction with the threaded hole, preventing the wire screw body from loosening and falling off, thereby improving the connection strength between the connectors. After the wire screw insert is screwed into the threaded hole of one of the connectors, the mounting handle is rotated outward so that the mounting handle is separated from the interior of the connector, making it convenient to install and remove the mounting handle, avoiding external force cutting off the mounting handle and causing the wire screw insert to loosen, and can be recycled.

[0004] In actual application, the above technical solution is to disassemble the installation handle by twisting it off. However, the twisting off process may cause the wire screw sleeve to slide, affecting its installation accuracy. In addition, the twisting off method is not convenient for the installation of the wire screw sleeve.

[0005] Therefore, it is necessary to invent a wire screw sleeve that is easy to install to solve the above problems. Utility Model Content
