Abstract

This utility model provides a variable diameter bucket body pin, relating to the field of bucket body pin technology. It includes a variable diameter seat, which is radially inserted into the main pin seat. The variable diameter unit can change the effective outer diameter under the control of the adjustment unit, thus adapting to bucket body connections for different working conditions and equipment models, and accommodating various hole diameter requirements. Simultaneously, the adjustment unit has a self-locking structure, preventing accidental changes in the effective outer diameter during use. This solves the problem of existing bucket body pins with fixed diameters, where the bucket body connection hole sizes differ for different working conditions and equipment models, and the connection hole diameter increases due to wear after long-term use. Traditional fixed-diameter bucket body pins cannot adapt to various hole diameter requirements, necessitating the stocking of multiple specifications of pins, increasing equipment maintenance costs and spare parts management difficulty.
