Oil pressure balance structure, brake lever, brake caliper, cable-actuated hydraulic conversion pump

An oil pressure balance structure, which is used in conjunction with a pump mechanism, wherein the pump mechanism is provided with at least one oil cylinder chamber, at least one oil reservoir chamber, and an oil pressure balancing component;

• the oil cylinder chamber is formed on the pump body and is communicated to an oil outlet in a radial direction;
• the oil reservoir chamber is formed on the pump body and is communicated to the oil cylinder chamber through a communication hole, and the oil reservoir chamber and the oil cylinder chamber are filled with brake fluid;
• and
• the oil pressure balancing component is arranged inside the oil reservoir chamber to replenish brake fluid to the oil cylinder chamber during braking to balance brake oil pressure;
• the oil pressure balancing component comprises a piston, an oil seal plug, and an oil reservoir chamber cover, wherein the piston is movably arranged inside the oil reservoir chamber, an annular outer wall of the piston is movably sealed with an inner wall of the oil reservoir chamber, and the piston moves toward a direction where the communication hole is located during braking, so as to replenish the brake fluid to the oil cylinder chamber during braking to balance brake oil pressure;
• the oil reservoir chamber cover is fixedly arranged on an open end of the oil reservoir chamber, and the oil reservoir chamber cover is provided with a balance hole communicating to external atmospheric pressure;
• the oil pressure balancing component further comprises a fluid replenishment channel, and a oil seal plug, wherein the fluid replenishment channel is formed and axially penetrates on the piston;
• a middle of the oil seal plug is provided with an external threaded section, and the external threaded section is assembled with an internal threaded surface formed on an inner wall of the fluid replenishment channel to seal the fluid replenishment channel;
• an inner cavity of the fluid replenishment channel is provided with a tapered sealing surface, and a tail of the oil seal plug is formed with a tapered end that cooperates with the tapered sealing surface to seal the fluid replenishment channel.
