Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in attached

drawings

1 and 2, a front fork structure of a frame comprises a front fork vertical tube 1, a front fork shoulder 2, a left support beam 3 and a right support beam 4, wherein the left support beam 3 and the right support beam 4 are symmetrically arranged on two sides of the front fork shoulder 2, the front fork is characterized in that a threading hole is formed in the front fork shoulder 2 in a penetrating mode, one end of the front fork vertical tube 1 is arranged on the front fork shoulder 2, and a threading channel corresponding to the threading hole is formed in the front fork vertical tube 1. Front fork standpipe 1 is both ends open-ended hollow tube body structure, and the top of front fork standpipe 1 stretches into to the inner chamber of handlebar in, and the control pencil on the handlebar passes through the inside of handlebar, then stretches into to the inner chamber of front fork standpipe from the top opening of front fork standpipe 1 again, through wires hole and the threading passageway that sets up in the front fork, can hide the pencil, promotes the holistic outside aesthetic property of frame, protects the pencil simultaneously.

Front fork shoulder 2 includes from bottom opening and communicates in the fork shoulder cavity 5 of through wires hole, and front fork shoulder 2 is the casting formula structure, reserves the line hole that supplies the braking brake line to pass through simultaneously, the bottom of front fork standpipe 1 is worn to establish and is stretched into to fork shoulder cavity 5 through the through wires hole in, just one of front fork standpipe 1 is located fork shoulder cavity 5 and serves and be provided with fender ring 6, and the front fork standpipe passes front fork shoulder, increases area of contact between the two, increases stability, front fork standpipe 1 and the equal welded connection in two hole edges of through wires hole increase welding area, promote the fastness.

The side wall of the front fork shoulder 2 is provided with at least one wire passing hole 7 corresponding to the fork shoulder cavity 5, the wire passing hole is at least used for passing a brake wire, the left support beam 3 or the right support beam 4 is provided with a brake support 8, and a wall body close to the brake support 8 is provided with a brake wire through hole 9; the brake wire stretches into the inner side of the left support beam 3 or the right support beam 4 with the brake wire through hole 7, so that the brake wire harness is hidden and is led out from the brake wire through hole close to the brake bracket 8 to the outside, the brake wire can be partially hidden, and the attractiveness is improved.

The left supporting beam 3 is the same as the right supporting beam 4 in structure and is a metal stamping part of a half shell-shaped structure, the top ends of the left supporting beam 3 and the right supporting beam 4 are spliced with the front fork piece 2, the splicing part is connected through welding, and polishing is carried out after the welding.
