Description

Technical Field

[0001] This utility model relates to the field of bicycle front fork technology, and in particular to a quick-release bicycle front fork locking mechanism. Background Technology

[0002] Quick-release bicycle forks are of great significance in bicycle design and use. For situations where the fork needs to be frequently disassembled, such as during travel, athlete training, or bicycle maintenance, this design can save a lot of time and effort. Compared with traditional fork shanks, they are simpler and more aesthetically pleasing, enhancing the overall look of the bicycle. This is an important consideration for cycling enthusiasts who pursue fashion and individuality.

[0003] Existing bicycle fork adjustments require adjusting bolts or using a pressure pump to adjust the stiffness. The stiffness adjustment depends on adjusting the pre-compression of a single spring, resulting in a large range of spring pre-compression displacement and increasing the overall length of the shock absorber. When adjusting the overall height of the fork, some adjustments are made using an external stem, resulting in scattered adjustment measures. When adjusting simultaneously, the process may be cumbersome and require many tools.

[0004] Existing patent (publication number: CN218806336U) discloses a bicycle front fork adjustment mechanism. This utility model utilizes the coordinated use of an adjustment unit, adjustment component, handwheel, and piston plate two. By fixing the threaded sleeve and turning the threaded rod, the connecting plate moves, adjusting the position between piston plate one and piston plate two, adjusting the pre-compression of the shock absorber spring, and adjusting the air pressure between piston plate one and piston plate two. The stiffness is adjusted by dual adjustment of air pressure and spring pre-compression, reducing the displacement range required for adjusting the stiffness. This utility model also utilizes the coordinated use of an adjustment unit, fork shoulder, and guide rod. By fixing the threaded rod and turning the threaded sleeve, the threaded sleeve moves along the threaded rod and the reinforcing plate, causing the fork shoulder to move up and down, adjusting the relative position of the fork shoulder and the support sleeve, and changing the overall height of the front fork. The adjustment is relatively convenient and does not require tools.

[0005] Existing patents offer solutions to the above problems, but most existing bicycle forks are integrated designs, which take up a lot of space during installation and use and are inconvenient to disassemble.

[0006] To address this, a quick-release bicycle front fork locking mechanism is proposed. Utility Model Content
