Description

Technical Field

[0001] The utility model belongs to the technical field of threaded connector installation and relates to a wire thread sleeve installation tool. Background Art

[0002] Wire thread inserts (also known as threaded steel inserts or thread repair inserts) are widely used in mechanical structures, primarily to repair and strengthen threaded connections, especially in situations where the threads are worn, corroded, or broken. They effectively enhance the strength and service life of threaded connections and are widely used in industries such as automotive, aviation, marine, machinery manufacturing, and electronic equipment. However, the installation of wire thread inserts can be difficult and inefficient, leading to inconsistent installation quality and even wasted thread inserts and labor.

[0003] Currently, commercially available wire thread insert installation tools typically consist of a mounting rod with external threads on one end and a matching tool. While these tools can complete the installation of wire thread inserts, existing wire thread insert installation tools require extensive user manipulation and adjustment during installation. This is particularly true when screwing the wire thread insert into a hole, requiring the operator to perform multiple steps to ensure the correct positioning and insertion of the wire thread insert. This process is cumbersome for inexperienced operators and can easily lead to misalignment, tilting, or misalignment, resulting in unsuccessful installation. Improper operation during installation can damage the wire thread insert or prevent it from being installed correctly. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the above problems and provide a wire thread insert installation tool.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] A wire screw insert installation tool comprises a handle, a mounting portion is provided at one end of the handle, the mounting portion is provided with an external thread matching the wire screw insert, the end of the mounting portion is provided with two spaced-apart shifting posts, the end of the wire screw insert is provided with a shifting hook bent toward the inner side of the wire screw insert, the mounting portion is screwed into the wire screw insert through the external thread, and during the rotation of the mounting portion, one of the shifting posts is abutted against one side of the shifting hook, thereby driving the wire screw insert to rotate along with the mounting portion, thereby realizing the installation of the wire screw insert.

[0007] Furthermore, the pull hook extends radially along the wire screw sleeve, and its length does not exceed the inner diameter of the wire screw sleeve.

[0008] Furthermore, the two shifting pins are distributed at 180 degrees on the end surface of the mounting portion, that is, symmetrically distributed, which can ensure that the maximum stretching amount of the wire thread insert is no more than 0.5 times the pitch.

[0009] Furthermore, the length of the shifting pin is 1.5 to 2.5 times the pitch of the wire thread sleeve.

[0010] Furthermore, the handle is provided with anti-slip grooves.

[0011] Furthermore, the shifting post is cylindrical or prismatic.

[0012] The beneficial effects of the present invention are:

[0013] 1. This utility model uses a lever and hook to drive the wire screw insert. The handle is connected to the wire screw insert via a thread. The helical characteristics of the thread are used to drive the lever in a spiral motion during rotation until the lever and hook abut against each other, achieving unidirectional circumferential drive of the wire screw insert to install it into the threaded hole. The lever and hook cooperate to achieve stable screwing of the wire screw insert. The operator only needs to use the handle to rotate the tool to complete the installation of the wire screw insert, simplifying the operation process and greatly improving installation efficiency.

[0014] 2. This utility model utilizes a two-pole design, effectively reducing the stretching of the wire thread insert caused by the end face of the mounting portion already contacting the hook before the pegs are engaged. The angle between the pegs and the axis is required to be 180°, i.e., symmetrical relative to the axis. This ensures that the maximum stretching does not exceed 0.5 times the thread pitch. A limit is also imposed on the peg length; theoretically, a length no less than the thread pitch will prevent stretching. In practice, considering factors such as the thread cross-section profile, safety margin, and experience, the peg length is designed to be 1.5-2.5 times the thread pitch.

[0015] Other advantages, objectives, and features of the present invention will be described in detail in the following description and, to some extent, will be apparent to those skilled in the art upon examination and study of the following or may be learned from practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
