Description

Technical Field

[0001] This utility model relates to the field of semi-threaded screw technology, and in particular to a bundled rod semi-threaded screw with a built-in washer. Background Technology

[0002] Half-thread screws are a special type of screw, commonly used in construction and industrial maintenance. Existing bundled half-thread screws are combined with washers, with the screw and washer being separate. When using them, the washer must be manually threaded through the threads first, which is time-consuming and laborious. Therefore, a bundled half-thread screw with built-in washers is needed.

[0003] Traditional tie rod semi-threaded screws are inefficient in use because they are inconvenient to limit positioning and prevent washer from falling off, thus hindering labor intensity and saving assembly time. Utility Model Content

[0004] The purpose of this invention is to provide a bundle rod semi-threaded screw with a built-in washer to solve the defect of existing bundle rod semi-threaded screws with built-in washer that are inconvenient for limiting position.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bundle rod half-thread screw with built-in washer, including a screw head and a bundle rod body;

[0006] One end of the screw head is fixed to the bundle rod body, and the outer side of one end of the bundle rod body is threaded.

[0007] A limiting structure is fixed on the outer side of the bundle rod body near the screw head. The limiting structure includes an inclined surface, a limiting ring, and a protective coating. The limiting ring is fixed on the outer side of the bundle rod body near the screw head. An inclined surface is provided on the outer side of one end of the limiting ring. A protective coating is provided on the outer side of both the limiting ring and the inclined surface.

[0008] An anti-loosening structure is provided on the outer side of the tie rod body on one side of the limiting structure.

[0009] When using this device, the limiting structure facilitates its anti-dislodgement function, thereby improving the working efficiency of the bundle rod half-thread screw; the anti-loosening structure facilitates its tightening function, thereby improving the applicability of the bundle rod half-thread screw.

[0010] Preferably, the anti-loosening structure includes a washer body, a corrosion-resistant layer, and a wear-resistant layer. The washer body is sleeved on the outside of the bundle rod body. The outer side of the washer body is provided with a corrosion-resistant layer, and the outer side of the corrosion-resistant layer is provided with a wear-resistant layer.

[0011] Preferably, the corrosion-resistant layer is actually an epoxy coating, and the wear-resistant layer is actually a polyurethane coating. The corrosion-resistant layer provides good adhesion and corrosion resistance, while the wear-resistant layer provides additional scratch and corrosion resistance, thereby improving the service life of the washer body.

[0012] Preferably, one side of the wear-resistant layer contacts one end of the screw head, and the other side of the wear-resistant layer contacts one side of the protective coating. Under the action of the washer body, loosening caused by vibration or impact can be effectively reduced, thereby ensuring the tightening force during connection.

[0013] Preferably, the outer diameter of the bundle rod body is 5.12 mm.

[0014] Preferably, the outer diameter of the limiting ring is larger than the bore diameter of the washer body. The limiting ring prevents the washer body from detaching, allowing the customer to directly assemble it into the workpiece without manually assembling the washer body first, thus reducing labor intensity and saving assembly time.

[0015] Preferably, the protective coating is actually a nano-coating. The inclined surface facilitates the automatic washer assembly machine's mounting of the washer body onto the outer side of the bundle rod body. The protective coating significantly improves the wear resistance and corrosion resistance of the retaining ring, thereby extending its service life.

[0016] The advantages of the bundle rod semi-threaded screw with built-in washer provided by this utility model are as follows:

[0017] By setting a limiting structure, the inclined plane facilitates the automatic washer assembly machine to assemble the washer body onto the outside of the bundle rod body. The protective coating significantly improves the wear resistance and corrosion resistance of the limiting ring, thereby extending its service life. The limiting ring prevents the washer body from falling off, allowing customers to directly assemble it into the workpiece without the need for manual assembly of the washer body first and then into the workpiece. This reduces labor intensity and saves assembly time, achieving the device's easy anti-fall-off function and improving the working efficiency of the bundle rod half-thread screw during use.

[0018] By incorporating an anti-loosening structure, the corrosion-resistant layer provides excellent adhesion and corrosion resistance, while the wear-resistant layer offers additional scratch and corrosion protection, thereby extending the service life of the washer body. The washer body also effectively reduces loosening caused by vibration or impact, ensuring a secure connection and facilitating fastening. This enhances the applicability of the semi-threaded bolt during use. Attached Figure Description
