In mining and large-scale earthworks, excavator Bucket teeth are the core components that directly bear high-frequency impacts and lateral shear forces. The stability of their connection directly affects the operational efficiency and safety of the entire machine. For a long time, traditional bucket teeth have been prone to loosening or even falling off of positioning bolts due to vibration after long-term high-intensity operation, which not only increases the cost of equipment shutdown and maintenance, but also brings significant safety hazards that cannot be ignored.

In response to the pain points in this industry, the domestic construction machinery parts field has achieved significant technological breakthroughs. The latest developed safety and stability bolt bucket teeth, through innovative structural design, introduce an expansion locking mechanism of sleeve and threaded rod between the bucket tooth head and the bucket tooth seat. This design utilizes the precise fit between the conical expansion block and the inner cavity of the bucket tooth seat to transform the traditional single bolt force into multi-point expansion clamping, fundamentally solving the problem of bolt loosening in vibration environments. At the same time, the new connection structure increases the effective contact area between the bucket teeth and the bucket, greatly improving the impact resistance and connection stability. Industry experts point out that the popularization of this technology not only effectively extends the service life of bucket teeth and tooth seats, reduces comprehensive maintenance costs, but also marks a solid step for China's excavator core wear-resistant components in terms of "high stability and high safety".
