Description

Technical Field

[0001] This utility model relates to the field of threaded fasteners, specifically to a bolt connection kit for preventing rust and seizure. Background Technology

[0002] Currently, bolts on the market consist of a bolt head and a threaded bolt shank, which are fastened together with a nut. When the bolt shank passes through the nut's through-hole, part of it remains inside the through-hole, while the other part protrudes outside. When the bolt needs to be removed, in humid environments, steel bolts are prone to rusting, causing the bolt to become stuck inside the nut's through-hole, making it impossible for the user to remove the bolt and resulting in inconvenience.

[0003] For all industries, if bolts and nuts are used as fasteners, they become difficult to disassemble when they rust, and removing the bolts is also difficult when repairing facilities after construction. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when bolts and nuts are used as fasteners in various industries, they become rusted and difficult to disassemble, making it difficult to remove the bolts during post-construction maintenance. This invention proposes a bolt connection kit that prevents rust from seizing.

[0005] This utility model is achieved through the following solution: a rust-proof bolt connection kit, which includes a bolt, a nut, a non-metallic rust-proof and anti-loosening washer, and a non-metallic film;

[0006] The non-metallic anti-rust and anti-loosening pad has an adhesive layer on one side and is fixedly connected to one end of a non-metallic film on the other side. The non-metallic film is long and strip-shaped, and has an adhesive backing layer on the back side of the other end. During operation, the non-metallic anti-rust and anti-loosening pad is fitted onto the threaded section of the bolt, the adhesive layer is bonded to the nut of the bolt, the non-metallic film is wrapped around the threaded section of the bolt, the adhesive backing layer is bonded to the threaded section of the bolt, and the nut is installed on the outside of the non-metallic film.

[0007] Furthermore, the non-metallic thin film is parallelogram-shaped.

[0008] Furthermore, multiple guide wires are evenly distributed within the non-metallic film. After the non-metallic film is wound onto the threaded section of the bolt, each guide wire corresponds to a groove on the bolt threaded section.

[0009] Furthermore, the guide wire and non-metallic film are integrated through a pressing process.

[0010] Furthermore, the non-metallic film is a non-metallic flexible film.

[0011] Furthermore, both the non-metallic anti-rust and anti-loosening pads and the non-metallic film are covered with an anti-corrosion layer.

[0012] Furthermore, the non-metallic anti-rust and anti-loosening pads, non-metallic films, and guide wires are all made of PVC or glass fiber.

[0013] Furthermore, the maximum cross-sectional diameter of the guide wire is smaller than the maximum spacing of the grooves on the bolt thread section.

[0014] Beneficial effects: This solution involves placing a non-metallic anti-rust and anti-loosening washer on the threaded section of the bolt, with the adhesive layer bonded to the bolt nut. The connection method is simple and the connection is stable. A non-metallic film is wrapped around the threaded section of the bolt, with the adhesive layer bonded to the threaded section. The connection method is simple and the connection is stable. The nut is installed outside the non-metallic film. In summary, the bolt and nut are not directly connected. Even if rust occurs, the non-metallic anti-rust and anti-loosening washer and the non-metallic film separate the bolt and nut, preventing direct contact and reducing the risk of seizing up. This facilitates bolt disassembly and makes it easier to remove bolts during post-construction maintenance. Using this solution as a connector provides strong fastening performance and good shock absorption, especially effective on machines with high vibration levels. Attached Figure Description
