Technical Field

[0001] This utility model relates to the field of reinforcing bolts for heavy machinery, specifically a reinforcing bolt for heavy machinery. Background Technology

[0002] The technical background of reinforcing bolts for heavy machinery is mainly reflected in three aspects: the application of high-strength materials, precision machining technology, and special structural design. In terms of materials, Q235 carbon steel can significantly improve its density and strength through hot forging / cold forging and heat treatment processes, while surface treatments such as hot-dip galvanizing can enhance its corrosion resistance.

[0003] However, it still has some drawbacks. For example, the current reinforcing bolts used for heavy machinery have a relatively simple structure. In strong earthquake environments and with severe vibrations from heavy machinery, the bolts are prone to loosening, which reduces their practicality.

[0004] To address the aforementioned problems, this application proposes a reinforcing bolt for heavy machinery. Utility Model Content

[0009] Preferably, the connecting nut is threaded to the outer wall of the threaded rod via a connecting threaded hole.

[0010] Preferably, the first sealing ring and the second sealing ring are tightly fitted to one side of the connecting threaded hole via threaded rods.

[0011] Preferably, the movable block is located inside the cavity of the fixed block.

[0012] Preferably, the clamping block is arc-shaped, and there are two sets of clamping blocks. The clamping blocks are located on the outer wall of the threaded rod through connecting threaded holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

These two sealing rings are respectively tightly fitted to one side of the threaded hole via a threaded rod, effectively preventing liquid or gas leakage at the bolt connection and improving overall sealing performance. It is particularly suitable for heavy machinery applications requiring high pressure or high sealing. The designed knob, slidably connected to the movable block via a bidirectional screw, allows users to easily adjust the distance between the two sets of clamping blocks by rotating the knob. This design not only simplifies installation and disassembly but also allows the bolt to adapt to fasteners of different sizes, improving versatility and practicality. Furthermore, the anti-slip pads on the inner side of the clamping blocks further enhance... The design enhances clamping stability, preventing loosening due to vibration or external forces.
