[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the high-strength fastener provided by this utility model; Figure 2 for Figure 1 The diagram shows a side sectional view of the nut. Figure 3 for Figure 1 The diagram shows the structural schematic of the hexagonal sleeve from the bottom view. Figure 4 for Figure 1 The diagram shows a side sectional view of the limiting component. A high-strength fastener, such as... Figure 1 As shown, the high-strength fastener of this embodiment includes: a nut 10 and a stud 20. The bottom of the nut 10 is fixedly connected to the top of the stud 20. An adjustment component 30 is provided on the inner side of the nut 10, and a limit component 40 is provided on the outer edge of the stud 20.

[0023] The adjustment assembly 30 includes a rotating rod 31 rotatably disposed inside the nut 10, a hexagonal sleeve 32 sleeved on the outer edge of the rotating rod 31, a hexagonal column 33 fixedly installed inside the hexagonal sleeve 32, a lifting port for the hexagonal column 33 to slide up and down opened at the top of the rotating rod 31, and an elastic element 34 for driving the hexagonal column 33 to descend fixedly installed inside the lifting port.

[0024] By pulling the hexagonal sleeve 32 upward through the pull groove, the inner side of the lifting port of the hexagonal column 33 moves upward, and the elastic element 34 is stretched to deform. When the hexagonal sleeve 32 disengages from the inner side of the notch 36, the tool drives the hexagonal sleeve 32 to rotate. The hexagonal sleeve 32 drives the rotating rod 31 to rotate through the action of the hexagonal column 33 and the connecting block 35. After adjustment, the reaction force of the elastic element 34 drives the hexagonal sleeve 32 to engage with the inner side of the notch 36, thereby limiting the hexagonal sleeve 32 and the rotating rod 31, which can strengthen the fastening effect with the parts and has a simple structure.

[0025] The limiting component 40 includes a threaded rod 41 rotatably disposed inside the stud 20, a threaded ring 42 threadedly connected to the outer edge of the threaded rod 41 and located inside the stud 20, connecting blocks 43 fixedly installed on both the left and right sides of the threaded ring 42, a limiting ring 44 fixedly installed on the surface of the connecting blocks 43 and located on the outer edge of the stud 20, a first limiting member 45 fixedly installed on the top of the limiting ring 44 and located on the outer edge of the stud 20, and connecting grooves for the connecting blocks 43 to move up and down are opened on both the left and right sides of the stud 20.

[0026] The limiting ring 44 is fitted onto the surface of the stud 20, and the threaded ring 42 is attached to the surface of the threaded rod 41. The two connecting blocks 43 are aligned with the adjacent connecting grooves. The rotating rod 31 drives the threaded rod 41 to rotate. Through the threaded connection between the threaded rod 41 and the threaded ring 42, the connecting block 43 and the limiting ring 44 slide upward inside the stud 20, so that the first limiting member 45 at the top of the limiting ring 44 engages with the second limiting member 47 at the bottom of the nut 46, thereby limiting the nut 46, reducing the possibility of loosening of the device, and increasing the overall practicality.

[0027] The outer edge of the nut 10 is inlaid with a reinforcing rib 50, and there are six reinforcing ribs 50. A reinforcing liner 60 is fixedly installed at the bottom of the nut 10. A first connecting hole is opened on the inner side of the reinforcing liner 60 so that the rotating rod 31 can pass through.

[0028] The strength of the fasteners is ensured by the action of the reinforcing rib 50 and the reinforcing liner 60.

[0029] The outer edge of the rotating rod 31 has a groove near the top, and there are six grooves. A connecting block 35 is slidably provided on the inner side of each groove. The surface of the connecting block 35 is fixedly connected to the inner wall of the hexagonal sleeve 32.

[0030] The hexagonal sleeve 32 has pull grooves on both the front and rear sides, and the nut 10 has a notch 36 on the top that matches the hexagonal sleeve 32.

[0031] The threaded ring 42, connecting block 43 and limiting ring 44 are integrated into one piece. The bottom end of the rotating rod 31 passes through the top end of the stud 20 and is rotatably connected to it. The bottom end of the rotating rod 31 is fixedly connected to the top end of the threaded rod 41.

[0032] A nut 46 is fitted on the outer edge of the stud 20 and is threaded to it. A second limiting member 47, which is adapted to the first limiting member 45, is provided at the bottom of the nut 46 and located on the outer edge of the stud 20.

[0033] The working principle of the high-strength fastener provided by this utility model is as follows:

[0034] Step 1: Screw the stud 20 into the object to be fastened by clamping the nut 10. The strength of the fastener is ensured by the reinforcing rib 50 and the reinforcing liner 60. Then, screw the nut 46 into the outside of the stud 20 to lock it in place. Place the limiting ring 44 onto the surface of the stud 20, ensuring the threaded ring 42 fits against the surface of the threaded rod 41, and aligns the two connecting blocks 43 with the adjacent connecting grooves. Pull the hexagonal sleeve 32 upwards by pulling the groove, causing the inner side of the hexagonal stud 33's lifting port to move upwards and stretching the elastic element 34 to deform it. When the hexagonal sleeve 32 disengages from the inner side of the notch 36, rotate the hexagonal sleeve 32 using a tool. The movement is driven by the hexagonal column 33 and the connecting block 35 to rotate the rotating rod 31. The rotating rod 31 drives the threaded rod 41 to rotate. The threaded rod 41, through its threaded connection with the threaded ring 42, drives the connecting block 43 and the limiting ring 44 to slide upward inside the stud 20. This causes the first limiting member 45 at the top of the limiting ring 44 to engage with the second limiting member 47 at the bottom of the nut 46, thereby limiting the nut 46, reducing the possibility of loosening of the device, and increasing the overall practicality. After adjustment, the reaction force of the elastic member 34 drives the hexagonal sleeve 32 to engage inside the notch 36, thereby limiting the hexagonal sleeve 32 and the rotating rod 31.

[0035] Compared with related technologies, the high-strength fastener provided by this utility model has the following beneficial effects:

[0036] By cooperating with each other, the first limiting member 45 at the top of the limiting ring 44 and the second limiting member 47 at the bottom of the nut 46 are engaged together, thereby limiting the nut 46, reducing the possibility of loosening, and increasing the overall practicality. After adjustment, the reaction force of the elastic member 34 drives the hexagonal sleeve 32 to engage inside the notch 36, thereby limiting the hexagonal sleeve 32 and the rotating rod 31, which can strengthen the fastening effect with the parts and has a simple structure.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
