Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and in particular relates to a high-strength nut. Background Art

[0002] A nut is a mechanical part, also known as a nut. It is a part that can be fastened together with a bolt or screw through the inner thread, so that nuts and bolts of the same specification can be connected together. It is a component that must be used in all manufacturing machinery. According to the different materials, it can be divided into several types, such as carbon steel, stainless steel, and non-ferrous metals.

[0003] The nuts currently on the market have the following problems when used:

[0004] 1. In the actual use of traditional nuts, since the nuts are connected to the bolts by threaded connection inside, the two are mainly kept in contact by friction. The machine will inevitably vibrate when it is running. If it is in a vibrating environment for a long time, the nuts may shake or even fall off, and the connection strength is low.

[0005] 2. When most nuts are used, a wrench is usually used to clamp the outside of the nut during installation and disassembly, and then it is twisted after being clamped. After repeated use, the edges and corners of the nut may be worn and become rounded, making it difficult to clamp and twist it when used again. The edges and corners of most nuts are often not replaceable. Once they are worn, they can only be discarded, which easily causes waste of materials. Summary of the invention

[0028] In order to better understand the purpose, structure and function of the utility model, the high-strength nut of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, a high-strength nut of the utility model comprises a nut body 1, a screw hole 2 is provided on the surface of the nut body 1, a snap ring 3 is provided on the top of the screw hole 2, the bottom of the snap ring 3 is fixedly connected to the first slider 4, a first slide groove 7 is provided on the top of the nut body 1, and the first slider 4 is slidably connected to the inside of the first slide groove 7, so that the snap ring 3 can be connected to the nut body 1, so that it is not easy to fall off, the inside of the first slide groove 7 is fixedly connected to the fixing plate 6, and the surface of the fixing plate 6 is fixedly connected to the spring 5, and the other end of the spring 5 is embedded and connected to the inside of the first slider 4, so that before the nut is connected to the fastener, the snap ring 3 is pulled open first, and the snap ring 3 is loosened after the connection is completed, and the snap ring 3 will be clamped in the threaded ring of the fastener, so that the fastener can be clamped, making it difficult for the nut to separate from the fastener, thereby enhancing its connection strength.

[0030] A groove 15 is provided on the surface of the nut body 1, and the interior of the groove 15 is connected to the slide bar 14 by a sliding connection. The surface of the slide bar 14 is fixedly connected to the edge block 10, and the end of the groove 15 is fixedly connected to the bottom plate 11. The bottom of the edge block 10 is close to the bottom plate 11. In this way, when a corner is damaged, the edge block 10 at that location can be disassembled and replaced separately, avoiding the need to replace the entire nut, thereby reducing material consumption.

[0031] The surface of the edge block 10 is inlaid with a metal sheet 13, and the surface of the bottom plate 11 is embedded with a magnet block 12. The metal sheet 13 is adsorbed and connected to the surface of the magnet block 12, so that the edge block 10 can be connected to the nut body 1 more tightly and is easy to disassemble.

[0033] The bottom of the retaining ring 3 is fixedly connected to the second slider 8, and the top of the nut body 1 is provided with a second slide groove 9. The second slider 8 is slidably connected inside the second slide groove 9, so that the movement of the retaining ring 3 on the top of the nut body 1 is smoother and it will not be easily displaced.

[0034] There are six edge blocks 10 distributed in a ring shape, so that all the edges and corners of the nut body 1 can be included, and the edge block 10 can be replaced at will if any edge or corner is worn.

[0035] The working principle of the high-strength nut is as follows: when in use, a screw hole 2 is provided on the surface of the nut body 1, a snap ring 3 is provided on the top of the screw hole 2, the bottom of the snap ring 3 is fixedly connected to the first slider 4, a first slide groove 7 is provided on the top of the nut body 1, and the first slider 4 is slidably connected to the inside of the first slide groove 7, so that the snap ring 3 can be connected to the nut body 1, so that it is not easy to fall off, the inside of the slide groove is fixedly connected to the fixing plate 6, and the surface of the fixing plate 6 is fixedly connected to the spring 5, and the other end of the spring 5 is embedded in the inside of the first slider 4. Before the nut is connected to the fastener, the pinch is first pushed outward to pull the snap ring 3 apart. At this time, the spring 5 is compressed and contracted. After the connection is completed, the pinch is released, and the spring 5 returns to its original state, that is, it rebounds in the direction of the screw hole 2, pushing the snap ring 3 to move inward until the snap ring 3 is clamped in the thread gap of the fastener, so that the fastener can be clamped, so that the nut cannot It is easy to detach from the fastener, which enhances its connection strength. A groove 15 is provided on the surface of the nut body 1. The inside of the groove 15 is connected to the slide bar 14 by a sliding connection. The surface of the slide bar 14 is fixedly connected to the edge block 10. The end of the groove 15 is fixedly connected to the bottom plate 11. The bottom of the edge block 10 is close to the bottom plate 11. In this way, when a corner is damaged, the edge block 10 is pushed upward to make the metal sheet 13 separate from the adsorption of the magnet block 12. Then the edge block 10 at this location can be disassembled and replaced separately, avoiding replacement of the entire nut and reducing material consumption. The bottom of the retaining ring 3 is fixedly connected to the second slider 8, and the top of the nut body 1 is provided with a second slide groove 9. The second slider 8 is slidably connected to the inside of the second slide groove 9, so that the movement of the retaining ring 3 on the top of the nut body 1 can be smoother. At the same time, the shape of the slider is "L" shaped, so that the retaining ring 3 will not be easily displaced.
