Adjustable bicycle work stand

Abstract

An adjustable bicycle support frame is provided for supporting a bicycle for repair or maintenance. The adjustable bicycle support frame includes a footrest, a top post, and a guide rod. The guide rod is mounted on the top post and has a first end and a second end. A support seat is provided at the first end of the guide rod to support the bottom bracket of the bicycle. A slide seat is slidably mounted at the second end of the guide rod. A support seat is pivotally mounted on the slide seat to support the bicycle's front fork, and the support seat is pivotally connected to the slide seat via a pivot assembly, allowing the support seat to pivot relative to the slide seat between a folded position and a supported position. This allows the support state to be adjusted according to actual usage needs, improving the flexibility and practicality of bicycle support.

Claims

1. An adjustable bicycle frame, comprising: Tripod; A vertical pole is attached to the scaffold. A guide rod, mounted on the upright, having a first end and a second end; a support, disposed at the first end of the guide rod, for supporting the bicycle bottom bracket; a slide, slidably disposed at the second end of the guide rod, having a first pivot portion; a support, pivotally disposed on the slide, having a support rod for supporting the bicycle front fork and a second pivot portion pivotally connected to the first pivot portion; and a pivot assembly, passing through the first pivot portion and the second pivot portion, allowing the support to pivot relative to the slide between a folded position and a supported position via the pivot assembly.

2. The adjustable bicycle work frame as claimed in claim 1, wherein a guide groove extending from the first end to the second end is provided on both sides of the guide rod, the slide seat has a sliding groove that slides on the guide rod, and a guide portion that is slidably engaged with the guide groove is provided on the two opposite inner wall surfaces of the sliding groove.

3. The adjustable bicycle frame as claimed in claim 1, wherein the pivot assembly includes a fastener, a first cam member, a second cam member, and an elastic member, the fastener being disposed through the first pivot portion, the second pivot portion, the second cam member, and the elastic member, and the fastener being detachably connected to the first cam member, the first cam member and the second cam member each having a cam surface that contacts each other, and the elastic member being biased between the first cam member and the second cam member, so that the support base can be positioned relative to the slide at multiple angular positions.

4. The adjustable bicycle frame as claimed in claim 3, wherein the first pivot portion includes a first lug, a second lug, and a third lug, and the second pivot portion includes a pair of fourth lugs, with the second lug located between the pair of fourth lugs.

5. The adjustable bicycle frame as claimed in claim 4, wherein the first pivot has a first polygonal hole, the second pivot has a second polygonal hole, the third pivot has a first through hole, the pair of fourth pivots each have a second through hole, the first cam member and the second cam member each have a polygonal cross-sectional shape, the first cam member is disposed in the first polygonal hole, the second cam member is disposed in the second polygonal hole, and the fastener passes through the first through hole, the second through holes, the second cam member and the elastic member, and is detachably connected to the first cam member.

6. The adjustable bicycle frame as claimed in claim 5, wherein the second pivot portion is provided with a limiting portion on the outer peripheral surface of each of the pair of fourth pivot ears, and the limiting portions are configured to abut against the slide when the support seat pivots relative to the slide seat to a maximum angular position.

7. The adjustable bicycle frame as claimed in claim 3, wherein the fastener has an external thread, the first cam has a screw hole, and the external thread is screwed into the screw hole, so as to adjust the bias force of the elastic member by changing the relative position of the fastener with respect to the first cam.

8. The adjustable bicycle frame as claimed in claim 3, wherein the elastic element is a compression spring.
