Hydraulic brake with travel adjustment mechanism

A hydraulic brake with travel adjustment mechanism, comprising:

• a brake body in which a pressure cylinder is arranged;
• a piston rod movably inserted into the pressure cylinder;
• a lever rotatably connected to one end of the brake body and forming a driving connection with the piston rod while being subjected to an external force;
• a spring that exerts force on the piston rod to maintain the piston rod in an initial position relative to the pressure cylinder when the lever is not subjected to an external force;
• a brake hose connected to the other end of the brake body and communicated with the pressure cylinder;
• and
• a connecting rod, one end of which is connected with the lever, and the other end of which is arranged in the pressure cylinder to form a driving connection with the piston rod;
• wherein, the pressure cylinder is internally provided with a limiting component, which interacts with the connecting rod to limit the connecting rod detachment from the pressure cylinder when the lever is not subjected to an external force;
• characterized in that:
• an adjustable chamber is arranged in the connecting rod, and an adjustment element passes through the adjustable chamber;
• wherein, one end of the connecting rod adjustment element extends into the adjustable chamber and forms a driving connection with the piston rod;
• when in use, the adjustment element can move relative to the adjustable chamber under an external force, thereby driving the piston rod to move forwards or backwards relative to the pressure cylinder, so as to adjust the initial position of the piston rod relative to the pressure cylinder;
• and after the adjustment is completed, the adjustment element can maintain the initial position after the movement;
• the limiting component comprises a snap spring fixedly connected to an inner wall of the pressure cylinder, and one end of the connecting rod is convexly provided with a ball joint, and the ball joint is positioned within the pressure cylinder and forms a limiting connection with the snap spring.
