Description

Technical Field

[0001] This utility model relates to the field of nuts, and more particularly to anti-slip nuts. 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. Based on the material, nuts are classified into several categories, such as carbon steel, stainless steel, and non-ferrous metals (e.g., copper).

[0003] In practical applications, even if the nut is tightened, it may gradually loosen or even fall off under the influence of various external factors, leading to connection failure and causing safety hazards or equipment malfunctions. Specifically, mechanical equipment will generate continuous vibration during operation (such as engines, motors, etc.). This repeated and minute displacement may weaken the friction between the threads, causing the nut to slowly loosen. In addition, under alternating loads, such as repeated force, bending, and tension, the connection position will undergo slight deformation, resulting in a decrease in preload.

[0004] Therefore, how to prevent the nut from slipping out, so that it can be stably connected to the connected parts, has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-slip nut that, when the bolt is screwed in, causes the nylon ring to undergo elastic deformation and generate a continuous radial clamping force on the bolt's external thread, significantly increasing the frictional resistance between the threaded pairs, thereby preventing the nut from rotating, loosening, or slipping, and achieving a stable and reliable connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nut body, wherein the nut body is hexagonal prism and has a threaded hole inside, the nut body extends axially up and down, and a nylon ring is located inside the threaded hole, the outer periphery of the nylon ring is fixedly connected to the nut body, the nylon ring is made of polyamide PA6, and the nylon ring has an internal thread.

[0007] The present invention is further provided with anti-slip pads located on each side of the nut body, each anti-slip pad being detachably connected to the upper and lower ends of the nut body, and each anti-slip pad being provided with anti-slip texture.

[0008] The present invention is further configured such that: each of the anti-slip pads is made of rubber and includes an upper connecting plate at the top, a lower connecting plate at the bottom, and a contact plate located between the upper connecting plate and the lower connecting plate, with each anti-slip pattern located on the corresponding contact plate, and the upper connecting plate and the lower connecting plate being detachably connected to the upper and lower ends of the nut body.

[0009] The present invention is further configured such that: a fixing plate is rotatably mounted on each of the upper connecting plates corresponding to the nut body, and the fixing plate is inserted into the upper connecting plate and detachably connected to the nut body.

[0010] The present invention is further configured such that: each of the fixed plates is provided with a first insertion hole, the upper connecting plate is provided with a second insertion hole corresponding to each of the first insertion holes, and the nut body is provided with a screw hole corresponding to each of the second insertion holes.

[0011] The present invention is further configured such that: the nut body is provided with an insertion groove for the upper connecting plate to be inserted, and the nut body is provided with limiting members protruding on both sides of the insertion groove, and the upper connecting plate is provided with limiting grooves corresponding to each limiting member.

[0012] The present invention is further configured such that: the upper connecting plate is provided with a connecting plug protruding downward, the connecting plug is provided with an inwardly recessed mating slot, the nut body is provided with a connecting slot corresponding to the connecting plug and a mating plug corresponding to the mating slot.

[0013] By adopting the above technical solution, since the nylon ring itself has elasticity, the bolt will pass through the nylon ring when it is screwed into the threaded hole. At this time, the elastic deformation ability of the nylon ring itself can be used to generate a radial clamping force on the bolt shank, thereby increasing the friction between the threaded pairs and thus preventing the nut from falling off after assembly. In addition, since PA6 material has good wear resistance, its service life in the threaded hole can be improved. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-6 As shown, this utility model discloses an anti-slip nut, including a nut body 1. The nut body 1 is hexagonal prism with a threaded hole 11 inside. The nut body 1 extends axially up and down and also includes a nylon ring 2 located inside the threaded hole 11. The outer circumference of the nylon ring 2 is fixedly connected to the nut body 1 by welding or other means. The nylon ring 2 is made of polyamide PA6 and has an internal thread (not shown in the figure). Because the nylon ring 2 has its own elasticity, when the bolt is screwed into the threaded hole 11, the bolt will pass through the nylon ring 2. At this time, the elastic deformation ability of the nylon ring 2 can be used to generate a radial clamping force on the shank of the bolt, thereby increasing the friction between the threaded pairs, thus achieving the goal of preventing the nut from falling off after assembly. In addition, since PA6 material has good wear resistance, its service life inside the threaded hole 11 can be improved.

[0019] In addition, it also includes anti-slip pads 3 located on each side of the nut body 1. Each anti-slip pad 3 is detachably connected to the upper and lower ends of the nut body 1 by means of bolts, buckles, etc. Each anti-slip pad 3 is provided with anti-slip textures 331. Since anti-slip pads 3 are installed on each side of the nut body 1 around the perimeter and each anti-slip pad 3 has anti-slip textures 331, the friction between the outer surface of the nut body 1 and the wrench can be increased during the assembly process, thereby reducing the possibility of slippage. In addition, the setting of detachable anti-slip pads 3 can effectively extend the overall service life of the nut and improve the convenience of disassembly and assembly.

[0020] Each of the anti-slip pads 3 is made of rubber and includes an upper connecting plate 31 at the top, a lower connecting plate 32 at the bottom, and a contact plate 33 located between the upper connecting plate 31 and the lower connecting plate 32. Each anti-slip pattern 331 is located on the corresponding contact plate 33. The upper connecting plate 31 and the lower connecting plate 32 are detachably connected to the upper and lower ends of the nut body 1. Since the upper connecting plate 31 and the lower connecting plate 32 of each anti-slip pad 3 are located on the upper and lower sides of the nut body 1 respectively, the contact area between each anti-slip pad 3 and the nut body 1 can be effectively increased, thereby facilitating the fixing between the two. After the upper connecting plate 31 and the lower connecting plate 32 are fixed to the nut body 1, each anti-slip pad 3 can be stably located on the side of the nut body 1, thereby stably increasing the circumferential friction of the nut body 1.

[0021] In this embodiment, each upper connecting plate 31 of the nut body 1 is rotatably mounted with a fixing plate 12. The fixing plate 12 is inserted into the upper connecting plate 31 and is detachably connected to the nut body 1. Due to the presence of each fixing plate 12 on the nut body 1, before each anti-slip pad 3 is installed on each side of the nut body 1, each fixing plate 12 needs to be rotated to move away from the position where the corresponding anti-slip pad 3 needs to be installed. After the positions of the upper connecting plate 31 and the lower connecting plate 32 are determined, each fixing plate 12 is rotated to move closer to the anti-slip pad 3 and press on the anti-slip pad 3. After the fixing of each fixing plate 12 and the nut body 1 is completed, the fixed connection between the upper connecting plate 31 and the nut body 1 is realized.

[0022] Preferably, each of the fixing plates 12 is provided with a first insertion hole 121, and each of the upper connecting plates 31 is provided with a second insertion hole 313 corresponding to each of the first insertion holes 121. The nut body 1 is provided with a screw hole 16 corresponding to each of the second insertion holes 313. By sequentially inserting bolts / screws (not shown in the figure) that are compatible with the screw hole 16 into the first insertion hole 121 and the second insertion hole 313, the screw hole 16 is threadedly engaged, thereby completing the fixing of each fixing plate 12 and the nut body 1. After each fixing plate 12 and the nut body 1 are connected, each of the upper connecting plates 31 is located between the fixing plate 12 and the nut body 1 and will not separate from the nut body 1, thus being stably connected to it.

[0023] Alternatively, a fixing plate 12 can be installed below the nut body 1, and a lower connecting plate 32 can be inserted to connect with the nut body 1, so that the upper and lower sides (i.e., the upper connecting plate 31 and the lower connecting plate 32) of each anti-slip pad 3 can be connected with the nut body 1, thereby enabling each anti-slip pad 3 to be stably located on each side of the nut body 1.

[0024] The nut body 1 is provided with an insertion groove 13 for the upper connecting plate 31 to be inserted. Limiting members 131 protrude from both sides of the nut body 1 in the insertion groove 13. The upper connecting plate 31 is provided with a limiting groove 311 corresponding to each limiting member 131. When the fixing plate 12 is rotated away from the upper connecting plate 31, the upper connecting plate 31 of the anti-slip pad 3 is inserted into the corresponding insertion groove 13. At this time, the upper connecting plate 31 needs to be bent upward so that the limiting groove 311 is above the corresponding limiting member 131, so that it moves downward. The limiting member 131 enters the limiting groove 311, so that the relative position of the upper limiting plate and the nut body 1 can be determined before the bolt / screw is installed, thus facilitating the installation of the bolt / screw.

[0025] Preferably, the upper connecting plate 31 has a downwardly protruding connecting block 312, and the connecting block 312 has an inwardly recessed mating slot 3121. The nut body 1 has a connecting slot 14 corresponding to the connecting block 312 and a mating block 15 corresponding to the mating slot 3121. During the process of the upper connecting plate 31 moving downward while the limiting groove 311 aligns with the corresponding limiting member 131, the connecting block 312 will enter the corresponding connecting slot 14. Because the connecting block 312 has an inwardly recessed... The mating slot 3121 is recessed, so the part of the connecting plug 312 located below the mating slot 3121 will first enter the connecting slot 14 and need to pass over the mating plug 15 to achieve the mating slot 3121 and the mating plug 15. Then, while the limiting groove 311 completes the engagement with the limiting member 131, the connecting plug 312 is stably located in the corresponding connecting slot 14, so that the connecting plug 312 completes the engagement with the connecting slot 14 without the action of external force, thus facilitating the insertion of bolts / screws.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
