front fork

Abstract

A fork includes a riser unit and a fork leg unit. The riser unit includes a riser, a connector, two reinforcing blocks, and a first solder. The riser has a bottom end. The reinforcing blocks are disposed on the connector and located on the front and rear sides of the bottom end. The first solder is welded between the connector and the bottom end, and between the periphery of each reinforcing block and the bottom end. The fork leg unit includes two forks and a second solder. Each fork leg has a connecting shoulder with a top edge, a bottom edge, and two mating edges. The connecting shoulders of the fork legs are disposed on the connector. Two front and rear opposing gaps are formed between the mating edges of the connecting shoulders of the fork legs. The second solder is welded along the gaps between the connecting shoulders of the fork legs and the connector, between the connecting shoulders of the fork legs and the reinforcing blocks, and between the connecting shoulders of the fork legs and the bottom end.

Claims

1. A fork, comprising: a riser unit including a riser, a connector disposed on the riser, two reinforcing blocks, and a first solder, the riser having a bottom end extending downward through the connector, the reinforcing blocks being disposed frontally and rearwardly opposite to each other on the connector and located on the front and rear sides of the bottom end, the first solder being soldered between the connector and the bottom end, and between the periphery of each reinforcing block and the bottom end; and a fork leg unit including two forks disposed on the riser unit, and a second solder, each fork leg having a connecting shoulder forming a engagement recess, the connecting shoulder having a top contact located at the top of the engagement recess. The connector comprises a bottom flange located at the bottom end of the joint recess, and two butt flanges connected between the two ends of the top flange and the two ends of the bottom flange and facing each other front and back. The connecting shoulders of the forks are disposed on the connector on the left and right opposite sides. The connector and the bottom end of the tube are embedded in the joint recess of the connecting shoulders of the forks. Two front and back opposite gaps are formed between the butt flanges of the connecting shoulders of the forks. The second solder is welded along the gaps between the connecting shoulders of the forks and the connector, between the connecting shoulders of the forks and the reinforcing blocks, and between the connecting shoulders of the forks and the bottom end of the tube.

2. The fork as described in claim 1, wherein, The connector has a large diameter section and a small diameter section extending downward from the large diameter section. The large diameter section has a bottom shoulder surface surrounding the small diameter section, and the small diameter section has a bottom ring surface surrounding the bottom end of the pipe. The reinforcing blocks are connected to the bottom ring surface. The first solder is welded between the bottom ring surface of the small diameter section and the bottom end of the pipe. The top edge of the connecting shoulder of the fork abuts against the bottom shoulder surface of the large diameter section.

3. The fork as described in claim 2, wherein, The fork unit also includes a third solder and a fourth solder. The third solder is welded along the top edge of the connecting shoulder of the fork to the connecting shoulder between the connecting shoulder of the fork and the connector. The fourth solder is welded along the bottom edge of the connecting shoulder of the fork to the connecting shoulder between the connecting shoulder of the fork and the bottom end of the tube.

4. The fork as described in claim 1, wherein, Each reinforcing block extends integrally downward from the connector.
