The pressing durability of the button combination security digits padlock is determined by the matching relationship between the interface material and the mechanical transmission. The button module of the device usually adopts a composite structure of an elastomer and a rigid substrate, and the contact surface is surface-modified to improve the anti-fatigue properties. The coordinated design of the stress relaxation coefficient of the elastic material and the trigger stroke allows the microscopic deformation generated by a single press to be fully released within the elastic recovery range.
The material of the button combination security digits padlock is brass. The contact switch of this material forms an anti-oxidation layer through a selective passivation process to inhibit the ablation effect of arc discharge on the contact surface. The guide angle optimization of the push rod mechanism reduces the lateral friction component and effectively transmits the force along the axial direction. The radial compression of the sealing ring is controlled within a reasonable range, which not only ensures the dust and water resistance of the button combination security digits padlock, but also avoids excessive extrusion to accelerate elastic failure.
The spring element in the button combination security digits padlock uses a two-phase heat treatment process to achieve a balance between hardness and toughness to prevent crack propagation caused by repeated bending. The gap compensation design between the button base and the housing allows for dimensional fluctuations caused by temperature changes and avoids mechanical jamming. The damping characteristics of the tactile feedback mechanism are optimized through dynamic simulation to ensure consistent operating feel while reducing impact loads.
