[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0021] Example: A type of threaded steel connector conversion fastener, such asFigure 1 、 Figure 2 and Figure 3 As shown in the drawings, the device comprises a fastener body 1, an arc-shaped fastener 2, a bolt 3, a gasket 4, a sliding rod 5, an arc-shaped plate 6 and an elastic member 7. The fastener body 1 is usually made of high-strength steel or alloy material to ensure the strength and durability of the fastener body 1. The arc-shaped fastener 2 is rotatably connected to one side of the fastener body 1 and is usually made of high-strength steel or alloy material to ensure the strength and durability of the arc-shaped fastener. The other side of the fastener body 1 is provided with the bolt 3. The arc-shaped fastener 2 is provided with a U-shaped opening at the end away from the fastener body 1 for the bolt 3 to pass through. The arc-shaped fastener 2 and the fastener body 1 form a closed circular space for wrapping around the threaded steel joint. The bolt 3 passes through the opening of the arc-shaped fastener 2 and is threadedly connected with a fastening nut. The bolt 3 and the fastening nut are usually made of high-strength steel to ensure the strength and corrosion resistance of the bolt 3 and the fastening nut. The arc-shaped fastener 2 is symmetrically provided with an arc-shaped slot on both sides of the opening as the center. The arc-shaped plate 6 is arranged in the arc-shaped slot. The sliding rod 5 is slidably connected to the arc-shaped plate 6. The arc-shaped plate 6 and the sliding rod 5 are usually made of high-strength steel to ensure the strength and durability of the sliding rod 5 and the arc-shaped plate 6. The end of the sliding rod 5 passing through the arc-shaped plate 6 is connected with the gasket 4. The gasket 4 is arranged in a structure of two metal sheets clamping a rubber member, which makes the gasket 4 have good elasticity and wear resistance. The gasket 4 deforms under stress and can reset when the extrusion force disappears, thereby ensuring the close fit of the fastening nut and the arc-shaped fastener 2 and the stability and reliability of the connection between the arc-shaped fastener 2 and the fastener body 1. The elastic member 7 is arranged between the gasket 4 and the arc-shaped plate 6 and is arranged around the sliding rod 5. The elastic member 7 is a rubber member or a spring with elastic properties and is used to provide elastic support for the gasket 4, ensuring that the gasket 4 can tightly adhere to the arc-shaped fastener 2 during tightening, thereby improving the stability and reliability of the connection between the arc-shaped fastener 2 and the fastener body 1. At the same time, the spring member 7 can absorb the impact force received by the bolt and the gasket, thereby avoiding the impact force impacting the fastening nut and causing the fastening nut to loosen from the bolt 3, thereby ensuring the reliability and stability of the connection between the fastening nut and the bolt 3. The depth of the arc-shaped slot arranged on the arc-shaped fastener 2 is greater than the sum of the thicknesses of the gasket 4 and the arc-shaped plate 6, which can avoid abnormal deformation of the elastic member 7.
[0022] Figure 1 and Figure 4As shown, the back of the arc-shaped buckle 2 is provided with an arc-shaped strip 8 in parallel, and a sliding block 9 is slidingly connected to the arc-shaped strip 8. A damper is arranged at the sliding connection between the sliding block 9 and the arc-shaped strip 8. The damper can prevent the sliding block 9 from sliding along the arc-shaped strip 8 autonomously. The sliding block 9 is connected to a chain hook 10 through a chain. The chain hook 10 is detachably connected to a hook ring 11 arranged on both sides of the arc-shaped part of the buckle body 1. The arc-shaped strip 8, the sliding block 9, the chain hook 10, and the hook ring 11 are usually made of high-strength steel to ensure the strength and durability of each component. Through the cooperation of the chain hook 10 and the hook ring 11, it is ensured that the arc-shaped buckle 2 can remain stable during the fastening process and prevent loosening.
[0023] Figure 2 As shown, the arc-shaped buckle 2 is provided with a non-slip pad 21 on the side facing the buckle body 1. The non-slip pad 21 is usually made of rubber or plastic material and has good non-slip performance. The side of the non-slip pad 21 away from the arc-shaped opening is sawtooth-shaped. This structure is beneficial to increase the friction coefficient between the non-slip pad 21 and the surface of the threaded steel joint, so that the non-slip pad 21 tightly adheres to the surface of the threaded steel joint, preventing the threaded steel joint from sliding during the fastening process and improving the stability and safety of the connection.
[0024] Figure 2 As shown, the arc-shaped part of the buckle body 1 is movably connected to an arc-shaped washer 12. The arc-shaped washer 12 is usually made of rubber or plastic material and has good elasticity and wear resistance. The arrangement of the arc-shaped washer 12 provides additional support and sealing effect, ensuring the stability and sealing performance of the connection part. The side of the arc-shaped washer 12 facing the buckle body 1 is uniformly provided with protrusions. The protrusions are movably clamped into the connecting grooves arranged on the buckle body 1. This arrangement facilitates the replacement of the arc-shaped washer 12 with faults.
[0025] In use, according to the specification of the threaded steel bars to be connected, select the threaded steel joint conversion fastener of corresponding specification, then install the fastener body 1 on one side of the threaded steel bar, ensure that the fastener body 1 is well fitted with the surface of the threaded steel bar; then, wrap the arc-shaped buckle 2 around the other side of the threaded steel bar, and fit it with the fastener body 1 to form a closed circular space, so as to wrap the threaded steel bar; the bolt 3 passes through the opening of the arc-shaped buckle 2, and the fastening nut is rotated to move the fastening nut towards the fastener body 1, the fastening nut gradually approaches the gasket 4 and abuts with the gasket 4, so as to extrude the gasket 4, the gasket 4 drives the sliding rod 5 to move and compresses the elastic member 7, until the fastening nut abuts with the arc-shaped buckle 2; when the threaded steel is subjected to vibration impact, the vibration force is transmitted to the fastener body 1 and the arc-shaped buckle 2 and released through the components connected with the fastener body 1 and the arc-shaped buckle 2, since the elastic member 7 is arranged between the gasket 4 and the arc-shaped plate 6, the vibration force from the arc-shaped buckle 2 can be resisted by the elastic member 7, thereby reducing the influence of the vibration force on the fastening nut, so as to ensure the stability and reliability of the connection between the fastening nut and the bolt 3, and avoid the fastening nut from loosening from the bolt 3, so as to ensure the stability of the arc-shaped buckle 2 and the fastener body 1.
