Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and more specifically relates to an anti-cracking nut. Background Art

[0002] Because copper nuts have the advantages of being not easy to rust, anti-corrosion, easy to conduct heat and strong electrical conductivity, they are generally used in rust-proof, high-temperature, conductive and thermally conductive environments, such as faucets, valves, electrical switches, etc.

[0003] However, when the copper nut is locally overheated, the overheated part will increase its brittleness, causing cracks inside. If it is subjected to excessive pressure, it is very easy to cause the copper nut to crack, thereby affecting the connection effect of the copper nut. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-cracking nut, which is sleeved with a reinforcement ring and can prevent the nut from cracking.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-cracking nut, comprising a hexagonal main body and a reinforcement ring, wherein the reinforcement ring is sleeved on the outside of the main body.

[0006] Furthermore, the main body includes a hexagonal section and a cylindrical section, the diameter of the cylindrical section is smaller than the diameter of the circumscribed circle of the hexagonal section, a step surface is formed between the cylindrical section and the hexagonal section, the reinforcement ring is sleeved on the outer surface of the cylindrical section and abuts against the step surface, and the outer diameter of the reinforcement ring is smaller than the diameter of the inscribed circle of the hexagonal section.

[0007] Furthermore, a limiting ring cover is provided on the cylindrical segment, and the outer side surface of the limiting ring cover is a hexagonal surface matching the hexagonal segment.

[0008] Furthermore, the limiting ring cover is provided with a connecting hole corresponding to the cylindrical section and a ring hole corresponding to the reinforcing ring, and the connecting hole is threadedly connected to the cylindrical section.

[0009] Furthermore, both ends of the main body are provided with cylindrical sections, and the cylindrical sections are provided with reinforcing rings and limiting ring covers.

[0010] Furthermore, at least one reinforcement ring is provided on the cylindrical segment, and the thickness of the cylindrical segment is smaller than that of the hexagonal segment.

[0011] Compared with the prior art, the beneficial effect of the utility model is: firstly a reinforcement ring is sleeved on the cylindrical section of the main body, and then the limiting ring cover is connected to form a complete nut. When the nut is used, the strong tensile strength of the reinforcement ring is used to improve the fracture resistance of the nut itself, thereby avoiding the nut from breaking during connection. Even if cracks are generated inside the nut due to local overheating, the reinforcement ring can ensure that the nut does not crack for a certain period of time and maintain its connection effect.

[0021] Embodiment 1

[0022] An anti-cracking nut comprises a hexagonal main body and a reinforcement ring 1, wherein the reinforcement ring 1 is sleeved on the outer side of the main body.

[0026] like Figures 2 to 4 As shown, in this embodiment, preferably, a limiting ring cover 5 is provided on the cylindrical segment 3 , and the outer side surface of the limiting ring cover 5 is a hexagonal surface that matches the hexagonal segment 2 .

[0027] In this embodiment, preferably, the inner diameter of the reinforcement ring 1 is slightly smaller than the outer diameter of the cylindrical section 3. When the reinforcement ring 1 is sleeved, the reinforcement ring 1 can be tightly sleeved on the cylindrical section 3 through interference fit, thereby improving the anti-cracking effect of the nut.

[0028] like Figure 1 As shown, in this embodiment, preferably, the limiting ring cover 5 is provided with a connecting hole 6 corresponding to the cylindrical segment 3 and a ring hole 7 corresponding to the reinforcement ring 1, and the ring hole 7 is used to wrap the reinforcement ring 1 to reduce the influence of the external environment on the reinforcement ring 1. Of course, only the connecting hole 6 can be provided and the reinforcement ring 1 can be exposed. The connecting hole 6 is threadedly connected to the cylindrical segment 3, and the connection of the limiting ring cover 5 is used to prevent the reinforcement ring 1 from slipping out of the cylindrical segment 3.

[0029] Preferably, in this embodiment, when the limiting ring cover 5 is connected to the cylindrical section 3, the hexagonal side surface on the limiting ring cover 5 corresponds one-to-one with the hexagonal side surface on the hexagonal section 2, making it convenient to use a tool such as a wrench to rotate the nut through the outer side surface of the hexagon.
