Description

Technical Field

[0001] The present invention relates to the technical field of temporary rail fastening, in particular to a fastener and a temporary rail. Background Art

[0002] Temporary track is often used to transport ore during mining operations. For example, during the development phase of small mines, temporary track facilitates the transport of mined ore from underground to surface processing plants or storage areas. Unlike conventional track, temporary track is typically laid without pre-embedded slabs. Instead, sleepers are directly fixed to the ground, and then the rails and sleepers are secured.

[0003] Fasteners, also known as railway track fasteners, are parts used to connect rails and sleepers on the track. They are also called intermediate connecting parts. Their function is to fix the rails to the sleepers, maintain the track gauge and prevent the rails from moving vertically and horizontally relative to the sleepers.

[0004] Fasteners include bolts and pressure plates. The bolts fix the pressure plates to the ground or on the sleepers, and the pressure plates press the rails to fix the rails. One end of the screw in the existing bolts is set underground, and the other end of the screw passes through the pressure plate and is connected to the nut. Due to the mining process, transportation equipment such as mine transport cars will generate frequent and large vibrations when running on temporary tracks. This continuous vibration will cause the nuts to be subjected to alternating stress, causing them to loosen. In order to prevent the nuts from loosening, staff are required to inspect the nuts regularly. However, the lighting conditions underground are poor, and inspection is inconvenient and easy to miss. Even if the inspection is carried out on time, the nuts may still be loose, posing a safety hazard. Summary of the Invention

[0005] In view of the above-mentioned shortcomings, the present invention provides a fastener and a temporary rail, wherein the fastener can effectively prevent the nut from loosening and prolong the maintenance time.

[0006] A first aspect of the present invention protects a fastener comprising a pressure plate, wherein the pressure plate is provided with a stopper, a spring assembly, and a nut assembly;

[0007] The stopper can rotate within the plane where the pressure plate is located. A bonding member is provided on a side of the stopper close to the nut assembly. The bonding member is detachable and the viscosity of the bonding member increases with increasing pressure.

[0008] The elastic force of the spring assembly causes the stopper to abut against the side wall of the nut assembly.

[0009] Furthermore, the nut assembly includes a first nut member and a second nut member having the same structure;

[0010] The stopper is disposed between the first nut member and the second nut member;

[0011] The stop member has a first end and a second end opposite to each other, and also has a first side and a second side opposite to each other. The first side of the first end of the stop member abuts against the side wall of the first nut member; the second side of the second end of the stop member abuts against the side wall of the second nut member.

[0012] Furthermore, the stopper comprises a strip plate, and the strip plate is arranged on the rotating shaft;

[0013] A first rubber block is provided on a first side of the first end of the strip plate, and a second rubber block is provided on a second side of the second end of the strip plate;

[0015] Furthermore, a rectangular through hole is provided in the center of the strip plate;

[0016] The top end of the rotating shaft is a rectangular end, and the rectangular through hole of the strip plate is sleeved on the rectangular end, so that the strip plate can be displaced along the axial direction;

[0017] A rotating shaft spring is provided between the rectangular end and the side wall of the rectangular through hole.

[0018] Furthermore, the first nut member includes a nut body, and a nut gear is sleeved on the outer side of the bottom of the nut body.

[0019] Furthermore, it also includes an upper cover, which is detachably arranged on the top of the pressing plate;

[0020] The pressing plate can also be detachably provided with a reminder component, and the reminder component abuts against the nut component;

[0021] When the nut assembly is loosened, the top end of the reminder assembly can be driven to protrude from the upper surface of the upper cover.

[0022] Furthermore, the reminder assembly includes a first reminder lever and a second reminder lever of the same structure;

[0023] The first reminder rod includes a threaded rod and a top block sleeved on the top of the threaded rod, and the threaded rod rotates to drive the top block to rise or fall;

[0024] The bottom of the threaded rod is sleeved with a screw gear.

[0025] Furthermore, the pressing plate is further provided with a pressing plate reminder block, the pressing plate reminder block comprises a hollow block, and the hollow block can be filled with a luminescent agent;

[0026] When the pressing plate is deformed or broken, the hollow block is broken and the luminescent agent inside flows out.

[0027] Furthermore, the pressing plate is provided with adjacent first shallow grooves and first deep grooves, and adjacent second shallow grooves and second deep grooves.

[0028] Countersunk holes are provided on the bottom surfaces of the first shallow groove and the second shallow groove;

[0029] Through holes are provided on the bottom surfaces of the first deep groove and the second deep groove;

When the temporary track needs to be dismantled, the adhesive can be easily removed, making it convenient to dismantle the nut. By providing a spring assembly, the stopper can press the nut assembly tightly. The pressure exerted by the stopper on the adhesive becomes greater, thereby increasing the viscosity of the adhesive and further preventing the nut assembly from loosening. The present invention can effectively extend the maintenance cycle of the nut assembly, prevent the nut assembly from loosening during the maintenance period as much as possible, and reduce safety hazards.

[0055] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0056] refer to Figures 1 to 10 A first aspect of the present invention protects a fastener, wherein the fastener 1 includes a pressing plate 11 , on which a stopper 14 , a spring assembly 15 and a nut assembly 13 are provided.

[0057] The stopper 14 can rotate within the plane of the pressure plate 11. Depending on the actual situation, the stopper 14 can be configured to rotate only within the plane of the pressure plate 11 and not move, in order to more effectively prevent the nut assembly 13 from loosening. The stopper 14 can also be configured to rotate within the plane of the pressure plate 11 and also move slightly in a specific direction. This configuration is intended to take into account the strong vibration during mining operations, and the small movement of the stopper 14 in the specific direction can act as a buffer.

[0058] An adhesive is provided on one side of the stopper 14 close to the nut assembly 13. The adhesive is detachably bonded, and the viscosity of the adhesive increases with the increase of pressure. Removable bonding means that it can be easily removed by pulling, or it can be easily removed by heating. In short, the adhesive can function normally without human intervention, and can also be easily removed with human intervention. The viscosity of the adhesive increases with the increase of pressure, which means that the viscosity of the adhesive can be increased by applying the pressure that can be provided by common parts such as springs relative to the state without pressure. In other words, the staff can increase the viscosity of the adhesive by manually applying pressure with their own strength. It does not mean that the pressure can be increased indefinitely. The purpose of increasing the pressure is also to expel the air so that the adhesive fits the nut assembly 13 completely.

[0059] The elastic force of the spring assembly 15 causes the stopper 14 to abut against the side wall of the nut assembly 13. The main function of the spring assembly 15 is to press the stopper 14 against the side wall of the nut assembly 13.

[0060] The present invention bonds the stopper 14 and the nut assembly 13 together by providing an adhesive. The adhesive force of the adhesive and the resistance of the stopper 14 can effectively prevent the nut assembly 13 from loosening. The adhesive is a detachable connection. When the temporary track needs to be dismantled, the adhesive can be easily removed, making it convenient to dismantle the nut. By providing a spring assembly 15, the stopper 14 can be pressed against the nut assembly 13. The pressure exerted by the stopper 14 on the adhesive becomes larger, which increases the viscosity of the adhesive relative to the pressure-free state, further preventing the nut assembly 13 from loosening. In addition, mining is subject to more frequent vibrations, which to a certain extent will accelerate the loosening of the adhesive, or even cause it to fall off the stopper 14 and lose its function. The provision of the elastic assembly 15 can continuously provide pressure to prevent the adhesive from loosening or falling off. The present invention can effectively extend the maintenance cycle of the nut assembly 13, prevent the nut assembly 13 from loosening during the maintenance period as much as possible, and reduce safety hazards.

[0061] refer to Figure 3 and Figure 4 In a specific embodiment, the nut assembly 13 includes a first nut member 131 and a second nut member 132 of the same structure. The first nut member 131 and the second nut member 132 are exactly the same in size and structure, and only have different locations. Figure 4 Taking the position in the figure as a reference, the first nut member 131 and the second nut member 132 are respectively arranged above and below in the figure.

[0062] The stopper 14 is disposed between the first nut member 131 and the second nut member 132 .

[0063] The stopper 14 has a first end and a second end opposite to each other, and also has a first side and a second side opposite to each other. The first side of the first end of the stopper 14 abuts against the side wall of the first nut member 131; the second side of the second end of the stopper 14 abuts against the side wall of the second nut member 132. Figure 4 Taking the position in the middle as an example, the upper end of the stopper 14 is the first end, the lower end is the second end, the left side of the stopper 14 is the first side, and the right side is the second side.

[0064] by Figure 4 For example, the stopper 14 is arranged obliquely between the first nut member 131 and the second nut member 132. The upper spring assembly 15 pushes the upper left side of the stopper 14 against the first nut member 131 while the lower right side of the stopper 14 automatically presses against the second nut member 132. Similarly, the lower spring assembly 15 pushes the lower right side of the stopper 14 against the second nut member 132 while the upper left side of the stopper 14 automatically presses against the first nut member 131. This arrangement of the stopper 14 more firmly presses the first and second nut members 131, 132, preventing them from loosening.

[0065] When the stopper 14 can move slightly in the axial direction, the tilting setting of the stopper 14 has another function. Figure 4 For example, the first nut member 131 and the second nut member 132 can be tightened by rotating clockwise and can be removed by rotating counterclockwise. The first nut member 131 and the second nut member 132 are also loosened in a counterclockwise direction in their natural state. Loosening of the first nut member 131 will apply a first loosening force to the upper right of the stopper 14, while loosening of the second nut member 132 will apply a second loosening force to the lower left of the stopper 14. The first loosening force and the second loosening force are in opposite directions, which can effectively prevent the first nut member 131 and the second nut member 132 from loosening.

[0066] It should be noted that in actual operation, the first nut member 131 and the second nut member 132 need to be tightened first, and then the stop member 14 is pressed against the first nut member 131 and the second nut member 132. In this embodiment, by providing the stop member 14, first, the first nut member 131 and the second nut member 132 can be prevented from loosening by means of compression and adhesion; second, the first loosening force and the second loosening force, which are in completely opposite directions, can offset each other to prevent the first nut member 131 and the second nut member 132 from loosening. The provision of the stop member 14 can effectively delay or prevent the first nut member 131 and the second nut member 132 from loosening, thereby increasing the safety of the temporary track.

[0067] refer to Figure 6 The stopper 14 includes a strip plate 141, and the strip plate 141 is arranged on a rotating shaft 142. The rotating shaft 142 can be inserted into the pressing plate 11, and the rotating shaft 142 rotates to drive the strip plate 141 to rotate.

[0068] A first rubber block 145 is provided on a first side of a first end of the strip plate 141 , and a second rubber block 143 is provided on a second side of a second end of the strip plate 141 .

[0069] The first adhesive block 145 and the second adhesive block 143 are both pressure-sensitive adhesives or hot melt adhesives. The application of pressure can make the pressure-sensitive adhesive contact the surface of the adherend more closely, fill the microscopic concave-convex structure, increase the actual contact area, and promote the close interaction between the adhesive layer molecules and the adherend molecules (such as van der Waals force), which is manifested as increased viscosity. Of course, the pressure cannot exceed the deformation tolerance limit of the adhesive layer. Similarly, the hot melt adhesive is fluid in the molten state. The application of pressure can make the glue spread more evenly on the surface of the substrate, fill the microscopic pores, increase the actual contact area, and accelerate molecular diffusion, such as the chemical bonding or van der Waals force between the glue and the substrate surface, which is also manifested as increased viscosity. The pressure should not cause excessive extrusion of the hot melt adhesive in the molten state.

[0070] Specifically, the pressure-sensitive adhesive can be a commercially available pressure-sensitive adhesive. Taking into account the different environments in different wells, different pressure-sensitive adhesives can be selected. For example, 3M 5915VHB pressure-sensitive adhesive can be selected. The short-term temperature resistance of this pressure-sensitive adhesive can reach 149°C and the long-term temperature resistance is 121°C. You can also choose Germany's Henkel's TECHNOMELT PS 3987, which can meet multiple requirements such as cold resistance, moisture resistance, high peelability, high shear resistance, high viscosity, clean removal and processing performance. You can also choose 3M 467MP, which can maintain viscosity in a humid environment. Of course, there are some other brands and models of pressure-sensitive adhesives on the market, such as Henkel, Siwu and BASF, which can be selected according to the specific usage scenarios. I will not go into details here.

[0071] Examples of hot melt adhesives include Bostik Themelt 861A, 3M 3789, and Conor King 1107-7. Some commercially available hot melt adhesives are both waterproof and moisture-proof, as well as heat- and low-temperature resistant. Some hot melt pressure-sensitive adhesives are also used in actual products and can also be used as adhesives.

[0072] In this embodiment, the pressure-sensitive adhesive is provided, which can exert greater viscosity under the action of pressure and can be easily removed when necessary, making it suitable for use in temporary rails. The hot melt adhesive is provided, which has better viscosity and stability. When removal is required, the hot melt adhesive can be removed by heating.

[0073] refer to Figure 4 and Figure 6 In a specific embodiment, a rectangular through hole is provided in the center of the strip plate 141. Specifically, a rectangular through hole is provided on the narrow side of the strip plate 141.

[0074] The top end of the rotating shaft 142 is a rectangular end, and the rectangular through hole of the strip plate 141 is sleeved on the rectangular end, so that the strip plate 141 can be displaced along the axial direction.

[0075] The rotating shaft 142 is composed of a disc, a cylinder and a cuboid connected in sequence from bottom to top. The cuboid is a rectangular end and can be inserted into a rectangular through hole. The thickness of the cuboid is the same as the width of the rectangular through hole, and the width of the cuboid is smaller than the length of the rectangular through hole. After the rectangular through hole is installed on the rectangular end, the strip plate 141 can move slightly along its own axial direction.

[0076] A rotation axis spring 144 is provided between the rectangular end and the side wall of the rectangular through hole. Specifically, a rotation axis spring 144 is provided between the two sides of the rectangular end and the side wall arranged in the axial direction of the strip plate 141.

[0077] This embodiment has two functions by setting the shaft spring 144. The first function is to reduce vibration. When mining, large vibrations will be generated. The vibration of the nut assembly 13 can be consumed by the spring assembly 15. The vibration of the shaft 142 can be directly transmitted to the adhesive, making it easy to fall off. Setting the shaft spring 144 can better reduce vibration and maintain the viscosity of the adhesive. The second function is to increase resistance. Figure 4 Taking the first nut 131 as an example, if the first nut 131 is loose, it is also necessary to overcome the elastic force of the shaft spring 144, which can further prevent the first nut 131 from loosening.

[0078] refer to Figure 7 In one embodiment, the first nut member 131 includes a nut body 1311. The nut body 1311 is a conventional commercially available nut capable of being threadedly connected to a screw. The nut shown in the figure is a hexagonal nut. A nut gear 1312 is sleeved on the bottom outer side of the nut body 1311. Nut gear 1312 is formed by machining the center hole of an existing conventional gear into a hexagonal hole, which is then sleeved on the outer side of the nut body 1311 and secured by welding.

[0079] The provision of nut gear 1312 in this embodiment serves two purposes. The first is to add a fixed structure. For example, by meshing nut gear 1312 with other fixed structures, it prevents the first nut member 131 from rotating, preventing loosening and reducing safety hazards. The second is to provide linkage with other structures. For example, it can be linked with reminder assembly 12. If the first nut member 131 becomes loose, it can activate reminder assembly 12 to alert personnel.

[0080] refer to Figure 1 and Figure 2 In one embodiment, the fastener 1 further includes an upper cover 17, which is removably mounted on top of the pressure plate 11. When connected to the pressure plate 11, the upper cover 17 forms a housing space containing the reminder assembly 12, the nut assembly 13, the stopper 14, the spring assembly 15, and the pressure plate reminder block 16. The top surface of the upper cover 17 is provided with a polygonal through-hole 171, which is an octagonal through-hole in the figure.

[0081] The pressing plate 11 is further provided with a detachable reminder component 12 , which abuts against the nut component 13 .

[0082] When the nut assembly 13 is loosened, the top end of the reminder assembly 12 can be driven to protrude from the upper surface of the upper cover 17 through the polygonal through hole 171 .

[0083] One of the functions of the upper cover 17 in this embodiment is to prevent dust. Mining will produce a lot of dust, and the upper cover 17 can effectively prevent dust. The upper cover 17 is detachable and easy to inspect and maintain. The polygonal through hole 171 can limit the protruding direction of the reminder component 12. By providing the reminder component 12, the reminder component 12 can protrude from the upper cover 17 when the nut component 13 is loose. The advantage of this is that there is no need to manually use tools to check by twisting the nut component 13. A simple observation from the appearance can tell whether the nut component 13 is loose. In actual applications, for a nut component 13 that is suddenly loose, the staff can see it in time and tighten the relevant nut component 13 to reduce safety hazards. Another function of the upper cover 17 is to prevent the aging of internal adhesives and other components and extend the service life of the adhesives.

[0084] refer to Figure 4 and Figure 8 In a specific embodiment, the reminder component 12 includes a first reminder rod 121 and a second reminder rod 122 with the same structure. Figure 8 The first reminder lever 121 is shown. The second reminder lever 122 is the same as the first reminder lever 121 and is not shown again.

[0085] The first reminder rod 121 includes a threaded rod 1212 and a top block 1211 mounted on the top of the threaded rod 1212. The rotation of the threaded rod 1212 can drive the top block 1211 to rise or fall. Specifically, when the threaded rod 1212 is stationary, the top block 1211 is rotated, and the top block 1211 can spirally rise or spirally descend along the threaded rod 1212. Similarly, when the threaded rod 1212 is rotated, the top block 1211 is limited to not rotating, and the top block 1211 can rise or fall. The top block 1211 is polygonal and can be inserted into the polygonal through hole 171. Preferably, the top block 1211 is an octagonal prism. The octagonal prism can be inserted into the octagonal through hole, and the two fit together so that the octagonal prism can extend vertically from the octagonal through hole.

[0086] A screw gear 1213 is sleeved around the bottom of the threaded rod 1212. The bottom end of the threaded rod 1212 passes through the screw gear 1213 and is rotationally connected to the pressure plate 11. The screw gear 1213 meshes with the nut gear 1312. When the nut body 1311 is loosened, the screw gear 1213 drives the threaded rod 1212 to rotate, which in turn drives the top block 1211 to rise within the polygonal through-hole 171 and protrude from the top surface of the upper cover 17.

[0087] Preferably, the top of the top block 1211 is cone-shaped, and the surface of the top block 1211 is a reflective surface, which can be achieved by painting with reflective paint or sticking reflective stickers.

[0088] In this embodiment, by providing a reflective top block 1211, the nut assembly 13 is more visible when there is a light source underground, and the staff can easily find it and tighten the nut assembly 13 in time. The top block 1211 has a conical top, and the staff can judge the looseness of the nut assembly 13 based on the protruding area of the top block 1211, and further judge the urgency of the tightening and maintenance work.

[0089] refer to Figure 3 In one specific embodiment, the pressure plate 11 is further provided with a pressure plate reminder block 16. The pressure plate reminder block 16 comprises a hollow block that can be filled with a luminescent agent. When the pressure plate 11 deforms or breaks, the hollow block shatters, allowing the luminescent agent inside to flow out. The hollow block can be made of ordinary glass or plastic, and can break when the pressure plate 11 deforms or breaks significantly. The luminescent agent can be a commercially available conventional luminescent material, such as rare earth-activated aluminate luminescent powder, zinc sulfide luminescent powder, or luminescent plastic masterbatch. When the luminescent agent is a luminescent material, it is important to ensure that the entire or partial surface of the top surface of the upper cover 17 is transparent so that underground lights can illuminate the luminescent material and ensure that it absorbs light. Alternatively, some water can be added to the hollow block. When the hollow block breaks, the luminescent material inside will spill onto the ground, covering a large area and making it easily visible to passersby. The luminescent agent can also be a conventional fluorescent material available on the market, for example, it can be the material inside the fluorescent sticks used in concerts. It should be noted that when using fluorescent materials, the interior of the hollow block needs to be divided into multiple independent spaces, and the multiple independent spaces can be divided into multiple groups. Taking two groups as an example below, some conventional raw materials are used to produce fluorescence, and fluorescence can also be produced by any conventional method. One group of spaces can include hydrogen peroxide solution, water and phosphoric acid, and the other group of spaces can include dimethyl phthalate and phenyl oxalate. Of course, necessary solvents such as xylene are also included. I will not go into details here. When the hollow block is broken, the raw materials in the multiple groups of spaces are mixed and emit fluorescence, which serves as a reminder. In actual applications, both luminous materials and fluorescent materials can be added to the hollow block.

[0090] refer to Figure 5 In a specific embodiment, the pressing plate 11 is provided with adjacent first shallow grooves 111 and first deep grooves 112, and the adjacent first shallow grooves 111 and first deep grooves 112 are connected at the side. Adjacent second shallow grooves 114 and second deep grooves 115 are also connected at the side.

[0091] The bottom surfaces of the first shallow groove 111 and the second shallow groove 114 are provided with countersunk holes, the bottom end of the first reminder rod 121 is inserted into the countersunk holes of the first shallow groove 111, and the screw gear 1213 of the first reminder rod 121 is placed in the first shallow groove 111. Similarly, the bottom end of the second reminder rod 122 is inserted into the countersunk hole of the second shallow groove 114.

[0092] Through holes are formed on the bottom surfaces of the first deep groove 112 and the second deep groove 115. The through hole of the first deep groove 112 is used to pass the first screw 21, and the first deep groove 112 is used to accommodate the first nut 131. Similarly, the through hole of the second deep groove 115 is used to pass the second screw 22, and the second deep groove 115 is used to accommodate the second nut 132.

[0093] The pressing plate 11 is further provided with a first protrusion 113 and a second protrusion 116 .

[0094] The spring assembly 15 includes a first spring 151 and a second spring 152 of identical structure. The number of each of the first spring 151 and the second spring 152 can be one or more. One end of the first spring 151 is fixed to the first protrusion 113, and the other end of the first spring 151 is fixed to the second side of the first end of the strip plate 141. One end of the second spring 152 is fixed to the second protrusion 116, and the other end of the second spring 152 is fixed to the first side of the second end of the strip plate 141.

[0095] refer to Figure 9 and Figure 10 A second aspect of the present invention provides a temporary rail track comprising a prefabricated ground member 2, on which a rail 3 is mounted. The prefabricated ground member 2 and the rail 3 are secured together by the aforementioned fastener 1. During the temporary rail track installation, a first screw 21 and a second screw 22 are prefabricated on the bottom surface 23 where the track is to be laid, facilitating the installation of sleepers or fasteners 1. In practice, sleepers are installed on the ground 23 first, followed by the fasteners 1, though this is not shown in the figures. However, the fasteners 1 can also be installed on the sleepers to perform their corresponding functions, which will not be discussed further here. Figure 10 What is disclosed is that the rail 3 is directly reinforced on the ground 23 by the fastener 1, and the fastener 1 can play the function of preventing loosening and reminding.

[0096] refer to Figures 1 to 10 , a working process of the present invention is as follows:

[0097] First, place the rail 3 on the ground 23, then place the pressure plate 11 on the first screw 21 and the second screw 22. The pressure plate 11 is pre-installed with a stopper 14, a spring assembly 15, and a pressure plate reminder block 16. The first screw 21 enters the first deep groove 112 from the bottom, while the second screw 22 enters the second deep groove 115 from the bottom.

[0098] Next, manually press the strip plate 141 to compress the first spring 151 and the second spring 152 at both ends of the strip plate 141. Fasten the first nut 131 to the first screw 21, and the second nut 132 to the second screw 22. Then, loosen the strip plate 141 and press it again, so that the first side of the first end of the strip plate 141 is in close contact with the first nut 131, and the second side of the second end is in close contact with the second nut 132.

[0099] Again, insert the first reminder rod 121 into the first shallow groove 111, and note that the screw gear 1213 is engaged with the nut gear 1312. Similarly, insert the second reminder rod 122 into the second shallow groove 114.

[0100] Finally, install the upper cover 17, aligning the polygonal through-hole 171 with the top ends of the first and second reminder rods 121, 122, and pressing down to connect the upper cover 17 to the pressure plate 11. This connection is a conventional detachable connection and will not be described in detail here. At this point, the top ends of the first and second reminder rods 121, 122 are both within the polygonal through-hole 171 and do not protrude from the upper surface of the upper cover 17.

[0101] The fastener 1 provided by the present invention has the following advantages:

[0102] First, the nut assembly 13 is fixed by detachable bonding to prevent the nut assembly 13 from loosening. Alternatively, the first nut member 131 and the second nut member 132 may be bonded to both sides of the stopper 14 so that the stopper 14 can simultaneously prevent the first nut member 131 and the second nut member 132 from loosening.

[0103] Second, by arranging the reminder assembly 12, when the nut assembly 13 is loose, it can protrude from the upper surface of the loam cake 17, and the staff is convenient to find. In addition, by arranging the reflective surface, the top of the reminder assembly 12 is more obvious, and it is easy to just find at a longer distance.

[0104] Third, by providing the pressing plate reminder block 16 , it can serve as a reminder when the pressing plate 11 is deformed or broken.

[0105] The fastener 1 of the present invention prevents the nut assembly 13 from loosening. When the nut assembly 13 becomes loose, it drives the tip of the reminder assembly 12 to protrude beyond the upper cover 17, providing a warning. Furthermore, if the pressure plate 11 deforms or breaks, the pressure plate reminder block 16 shatters, causing the luminous agent to illuminate and alert personnel, effectively reducing safety hazards.

[0106] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
