Description

Technical Field

[0001] This utility model relates to the field of nut technology, and more specifically, to a novel fastening nut. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It is an essential component in all manufacturing machinery. Depending on the material, nuts are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals.

[0003] Currently, fastening nuts are generally hexagonal prisms, and can only be removed using a corresponding hex wrench. The removal method is relatively simple and inconvenient. In addition, after installation, one side of the fastening nut will be in close contact with the surface of the fastener, which can easily cause corrosion over a long period of time, further increasing the difficulty of removal. Therefore, it is necessary to propose a new type of fastening nut to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of fastening nut, which aims to improve the problem that fastening nuts are generally hexagonal prisms, and can only be disassembled with a corresponding hexagonal wrench. The disassembly method is relatively simple and not convenient. In addition, after installation, one side of the fastening nut will be in close contact with the surface of the fastener, which is prone to corrosion over a long period of time, which also increases the difficulty of disassembly.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a novel fastening nut, including a prism and a protective end cap.

[0007] The prism has a circular hole inside, and the inner surface of the circular hole has an internal thread. A pad is fixed to one end of the prism, and a protrusion is fixed to the surface of the pad. A strip groove and an insertion hole are formed on the surface of the prism, and the insertion hole communicates with the strip groove. The protective end cap is snapped onto the other side of the prism, and a filler is fixed to the surface of the protective end cap. The filler is snapped into the inside of the strip groove and the insertion hole.

[0008] In one embodiment of this utility model, the pad has a through hole that matches the circular hole, and an annular groove is formed inside the pad, with a washer fixed inside the annular groove.

[0009] In one embodiment of this utility model, the other end of the prism is provided with an annular groove that matches the protective end cap, and the protective end cap is snapped into the inside of the annular groove.

[0010] In one embodiment of this utility model, a plurality of protrusions are provided, and the plurality of protrusions are circumferentially distributed on the pad.

[0011] In one embodiment of this utility model, the strip groove and the insertion hole are circumferentially distributed on the prism, and the filler is provided correspondingly to the strip groove and the insertion hole.

[0012] In one embodiment of this utility model, the filler includes a filler strip, one end of which is fixed with a filler post, and the other end of which is fixed with a connecting strip. The connecting strip is fixed to the protective end cap. The filler strip is snapped into the inside of the strip groove, and the filler post is snapped into the inside of the insertion hole. The cross-section of the insertion hole is a regular hexagon.

[0013] The beneficial effects of this utility model are as follows: The novel fastening nut obtained through the above design allows for easy use. When the fastening nut is threaded onto the threaded post, the presence of several protrusions reduces the contact area with the fastener. The protective end cap is then inserted into the annular groove at one end of the prism, while the filler strip and filler post are secured in their corresponding slots and holes. This further protects the ends of the nut and threaded post. Disassembly is possible by directly using a hex wrench. The filler strip and filler post can also be removed, and a flathead screwdriver can be inserted into the slot or a hex wrench into the hole to rotate the fastening nut. This increases the versatility of disassembly and assembly, making it more flexible. The reduced contact area with the fastener and protection of the nut's end also reduce corrosion during prolonged use, making disassembly easier and more convenient. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0021] Please see Figures 1-4 This utility model provides a technical solution: a novel fastening nut, comprising a prism 100 and a protective end cap 200.

[0022] Please see Figures 1-4 The prism 100 has a circular hole 110 inside, and the inner surface of the circular hole 110 has an internal thread 111. A pad 120 is fixed to one end of the prism 100, and a protrusion 130 is fixed to the surface of the pad 120. A strip groove 150 and an insertion hole 151 are formed on the surface of the prism 100, and the insertion hole 151 is connected to the strip groove 150.

[0023] The pad 120 has a through hole that matches the circular hole 110. An annular groove 121 is formed inside the pad 120, and a washer 122 is fixed inside the annular groove 121. The washer 122 ensures tight contact with the contacted part. The other end of the prism 100 has an annular groove 160 that matches the protective end cap 200. The protective end cap 200 is snapped into the annular groove 160, allowing for easy installation and removal of the protective end cap 200.

[0024] Several protrusions 130 are provided, circumferentially distributed on the pad 120. The protrusions 130 reduce the contact area with the contacted parts, thereby reducing the possibility of corrosion and facilitating disassembly and assembly after long-term use. The strip grooves 150 and the insertion holes 151 are circumferentially distributed on the prism 100, and the filler 210 is provided correspondingly to the strip grooves 150 and the insertion holes 151.

[0025] Please see Figures 1-4 The protective end cap 200 is snapped onto the other side of the prism 100. A filler 210 is fixed on the surface of the protective end cap 200. The filler 210 is snapped into the inside of the strip groove 150 and the socket 151.

[0026] The filler 210 includes a filler strip 211, with a filler post 212 fixed to one end and a connecting strip 213 fixed to the other end. The connecting strip 213 is fixed to the protective end cap 200. The filler strip 211 is snapped into the inside of the strip groove 150, and the filler post 212 is snapped into the inside of the insertion hole 151. The cross-section of the insertion hole 151 is a regular hexagon. Here, the strip groove 150 allows for easy insertion of a flathead screwdriver, thus allowing the nut to be turned using a flathead screwdriver. At the same time, the cross-section of the insertion hole 151 is a regular hexagon, which allows for easy insertion of a hex wrench, thus allowing the nut to be turned using a hex wrench. This multiple method of rotating and disassembling the nut improves the flexibility of disassembly and makes it more convenient to use.

[0027] Specifically, the working principle of this new type of fastening nut is as follows: During use, the fastening nut is screwed onto the threaded post. The presence of several protrusions 130 reduces the contact area with the fastener. Then, the protective end cap 200 is engaged with the annular groove 160 at one end of the prism 100. Simultaneously, the filler strip 211 and filler post 212 are engaged in the corresponding slots 150 and insertion holes 151. This further protects the ends of the nut and threaded post. During disassembly, the fastening nut can be directly disassembled using a hex wrench. The filler strip 211 and filler post 212 can also be removed. A flathead screwdriver can be inserted into the slot 150, or a hex wrench can be inserted into the insertion hole 151 to rotate the fastening nut. This increases the versatility of disassembly and assembly, making it more flexible. It also reduces the contact area with the fastener and protects the ends of the fastening nut, thus reducing corrosion and simplifying disassembly during long-term use.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
