Description

Technical Field

[0001] The utility model relates to the technical field of thread fastening kits, in particular to an anti-loosening thread fastening kit. Background Art

[0002] Bolt assembly is a mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] Bolts can be seen everywhere in daily life. Existing bolts perform well in bolt connection. However, when bolts are connected to some active machinery, long-term use can easily cause the nuts to loosen. Loose nuts will generate vibrations due to long-term activity of mechanical equipment, which can easily drive the nuts to rotate. Over time, the bolts will loosen, requiring regular inspections, wasting a lot of manpower and material resources. Utility Model Content

[0025] The following further details the present utility model in combination with the full text:

[0026] Combined with the attached Figures 1 to 4 , a loosening-proof threaded fastening kit includes a mounting plate 1 and a rod body 2. The rod body 2 is provided with threads 3. The top of the rod body 2 is fixedly connected with a head 4. A groove 5 is provided below the head 4. A limiting groove 6 is provided on one side of the rod body 2. A gasket 7 is sleeved on the rod body 2. The gasket 7 is provided with a convex block 8. The convex block 8 slides in the limiting groove 6. The mounting plate 1 is provided with a mounting hole 9. The rod body 2 passes through the mounting hole 9. A nut 10 is threadedly connected to the rod body 2 through the threads 3. First, insert the gasket 7 into the groove 5, and insert the rod body 2 through the mounting hole 9 on the mounting plate 1, and then rotate and screw on the nut 10, so that the mounting plate 1 can be clamped and fixed. At this time, the limiting groove 6 limits the convex block 8, and the groove 5 limits the gasket 7, so that the gasket 7 will not deflect when the nut 10 is rotated, thereby enabling the gasket 7 to play a good role, improving the fastening effect, making the fixation more firm, and reducing the possibility of loosening.

[0027] Among them, an internal groove 11 is provided below the rod body 2, a retaining ring 12 is provided at the bottom of the internal groove 11, a fixing plate 15 slides in the internal groove 11, a limiting block 16 is fixedly connected to the fixing plate 15, a fixing rod 14 is fixedly connected below the fixing plate 15, a striking plate 13 is fixedly connected below the fixing rod 14, a top ring 17 is fixedly connected to the striking plate 13. The shape of the groove 5 is the same as that of the gasket 7 and the convex block 8. The thickness of the gasket 7 is greater than the depth of the groove 5. The gasket 7 and the convex block 8 are located in the groove 5. The head 4 is located above the mounting plate 1. The gasket 7 fits against the top of the mounting plate 1. The top of the nut 10 fits against the bottom of the mounting plate 1. Four groups of limiting blocks 16 are provided and are evenly distributed on the fixing plate 15. The inner diameter of the retaining ring 12 is smaller than the inner diameter of the internal groove 11. The fixing plate 15 and the limiting block 16 are located in the internal groove 11. The bottom of the limiting block 16 fits against the top of the retaining ring 12. The top of the top ring 17 fits against the bottom of the nut 10. The diameter of the striking plate 13 is greater than the diameter of the rod body 2. After the nut 10 is rotated, by using a tool to strike the striking plate 13, the fixing plate 15 and the limiting block 16 are driven into the internal groove 11, and the limiting block 16 is fixed by the retaining ring 12. At this time, the top ring 17 fits against the bottom of the nut 10. Further, due to the vibration generated by the operation of the device, the nut 10 falls off, improving the stability of the device during use, and the operation is simple and convenient, improving the practicability of the device.

[0028] Working principle of the utility model: When in use, first slide the gasket 7 sleeved on the rod body 2, and make the convex block 8 slide upward in the limiting groove 6 until the gasket 7 slides into the groove 5. Then insert the rod body 2 through the mounting hole 9 on the mounting plate 1, so that the bottom of the gasket 7 fits against the top of the mounting plate 1. Then tighten the nut 10 through the thread 3 on the rod body 2 until the top of the nut 10 fits against the bottom of the mounting plate 1. Finally, insert the fixing plate 15 and the limiting block 16 into the internal groove 11. When the limiting block 16 fits below the retaining ring 12, it is necessary to use a tool to strike the striking plate 13 until the fixing plate 15 and the limiting block 16 completely enter the internal groove 11. At this time, the bottom of the limiting block 16 tightly fits against the top of the retaining ring 12 and will not slip out, and the top of the top ring 17 tightly fits against the top of the nut 10, which can effectively prevent loosening during use and improve the stability.

[0029] The above describes the utility model and its implementation manners. This description is not restrictive. What is shown throughout the text is only one of the implementation manners of the utility model. The actual structure is not limited to this. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the utility model.
