Bicycle front fork vibration-proof structure

A bicycle front fork vibration-proof structure comprising a front fork tube and a vibration-proof device;

• the front fork tube being formed by a biforked tube and a front-fork stand tube;
• one end of the biforked tube being assembled with a front wheel of a bicycle;
• the front-fork stand tube being assembled to a connecting tube of a bicycle handle;
• wherein
• the biforked tube and the front-fork stand tube are separated from one another;
• the vibration-proof device is installed between the biforked tube and the front-fork stand tube;
• the vibration-proof device is formed by a pivotal linkage unit, and an axial vibration absorption unit;
• one end of the pivotal linkage unit is pivotally installed to a first pivotal portion at an outer edge of the connecting tube and another end thereof is pivotally connected to the axial vibration absorption unit;
• the axial vibration absorption unit is firmly secured to an inner edge of the front-fork stand tube by a C ring;
• the axial vibration absorption unit is formed by an axial connector, at least one vibration absorption body, and a concave washer;
• one end of the axial connector is protruded with a second pivotal portion for pivotally connecting the pivotal linkage unit;
• and an inner edge of the axial connector being installed with the vibration absorption body;
• and
• the concave washer is installed on the vibration absorption body for resisting and positioning a connecting tube of a handle of a tube which has been engaged to the front-fork stand tube;
• thereby, the vibration-proof effect of a bicycle is improved and the brake suspending frame can be installed easily.
