[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A high-strength impact-resistant bolt comprises a first connecting plate 1, a hexagonal hole 6 is provided on the upper surface of the first connecting plate 1, a nut 2 is clamped inside the hexagonal hole 6, a circular opening 10 is provided on the upper surface of the nut 2, two limit plates 3 are fixedly connected to the inner wall of the nut 2, two limit blocks 9 are fixedly connected to the inner wall of the nut 2, a circular column 7 is fixedly connected to the bottom surface of the nut 2, three groups of long strips 12 are fixedly connected to the outer surface of the circular column 7, a stud 4 is threadedly connected to the inner wall of the first connecting plate 1, a second connecting plate 5 is threadedly connected to the outer surface of the stud 4, the upper surface of the second connecting plate 5 is in contact with the bottom surface of the first connecting plate 1, and by providing the second connecting plate 5, the first connecting plate 1 and the second connecting plate 5 can be connected through the stud 4, thereby achieving a better connection effect.

[0024] The inner wall of the stud 4 is fixedly connected with three groups of annular blocks 11, and the outer surface of the stud 4 is threadedly connected with a threaded cap 8, and the upper surface of the threaded cap 8 is in contact with the bottom surface of the second connecting plate 5. By providing the threaded cap 8, the device can be installed from the bottom through the threaded cap 8, thereby making the connection between the first connecting plate 1 and the second connecting plate 5 more stable.

[0025] The number of annular blocks 11 and the number of long strip blocks 12 in each group are both two. The top of each annular block 11, the top of the long strip block 12 and the top of the stud 4 are all in contact with the bottom surface of the nut 2. The stud 4 includes a first impact-resistant layer 14. The outer surface of the first impact-resistant layer 14 is fixedly connected to the second impact-resistant layer 15. By providing the first impact-resistant layer 14 and the second impact-resistant layer 15, the impact resistance of the device can be increased by the first impact-resistant layer 14 and the second impact-resistant layer 15, thereby reducing the problem of breakage.

[0026] The outer surface of the circular column 7 is fixedly connected to the annular plate 13, the outer surface of the second impact-resistant layer 15 is fixedly connected to the third impact-resistant layer 16, and the outer surface of the third impact-resistant layer 16 is fixedly connected to the fourth impact-resistant layer 17. By providing the third impact-resistant layer 16 and the fourth impact-resistant layer 17, the third impact-resistant layer 16 and the fourth impact-resistant layer 17 can enhance the toughness of the bolt during operation, thereby avoiding the breakage of the bolt due to shaking.

[0027] The outer surface of the annular plate 13 contacts the inner wall of the stud 4, the outer surface of the fourth impact-resistant layer 17 is fixedly connected with the first anti-rust layer 18, the outer surface of the first anti-rust layer 18 is fixedly connected with the second anti-rust layer 19, and the outer surface of the second anti-rust layer 19 is fixedly connected with the third anti-rust layer 20. By providing the first anti-rust layer 18, the second anti-rust layer 19 and the third anti-rust layer 20, the rust resistance of the bolt can be increased by the first anti-rust layer 18, the second anti-rust layer 19 and the third anti-rust layer 20, thereby increasing the service life.

[0028] The working principle of the utility model is as follows: when using the device, the tool for rotating the nut 2 can be inserted into the interior of the nut 2 through the gap between the two limit plates 3, and the limit block 9 can be used to keep the tool under the limit plate 3, and then the tool is rotated to drive the circular column 7 to rotate, and the clamping relationship between the long strip block 12 fixed on the outer surface of the circular column 7 and the annular block 11 can be used to drive the stud 4 to rotate, thereby the stud 4 can be threadedly connected to the interior of the first connecting plate 1 and the second connecting plate 5. To ensure that the nut 2 does not enter the interior of the hexagonal hole 6, the circular column 7 fixed on the bottom surface of the nut 2 is used to transmit the rotating power to the stud 4. When the annular plate 13 fixed on the outer surface of the circular column 7 reaches the bottom of the annular block 11, the angle is adjusted to press the nut 2 into the hexagonal hole 6, thereby completing the limitation of the nut 2, thereby achieving the purpose of the automatic locking function. When the device needs to be disassembled, the tool is inserted under the limit plate 3 and then pulled upward. The nut 2 can drive the circular column 7 and the long strip 12 fixed on the outer surface of the circular column 7 to move upward, thereby driving the annular plate 13 to move upward as well, and the annular plate 13 can limit the circular column 7 to prevent the circular column 7 from leaving the range of the stud 4, thereby ensuring that the nut 2 can move straight upward, so that the nut 2 can leave the clamping range of the hexagonal hole 6, so that the tool can be used to apply rotational and upward power to the nut 2 at the same time, thereby completing the disassembly of the device, and the first impact-resistant layer 14, the second impact-resistant layer 15, the third impact-resistant layer 16 and the fourth impact-resistant layer 17 are respectively made of copper, nickel, silver and yttrium as raw materials, thereby increasing the overall impact resistance of the bolt, and the first anti-rust layer 18, the second anti-rust layer 19 and the third anti-rust layer 20 are respectively made of iron red, aluminum powder and graphite anti-rust paint as raw materials to provide the device with good anti-rust ability, thereby effectively avoiding the problem that the device cannot be automatically positioned during use, causing the bolt to easily fall off.
