Technical Field
[0001] The invention relates to the technical field of shoe buckles, in particular to a shoe buckle with a rebound function. Background Art
[0002] The buckle used to tighten the shoelaces on sports shoes is usually called a quick lacing system or a knob-type shoelace buckle. This design is a major innovation in modern sports shoe technology, aiming to provide users with a more convenient and efficient shoelace adjustment experience. The internal knob is the core component of the system, usually made of metal or high-strength plastic, with excellent durability and feel. Users control the tightness of the shoelaces by turning the knob, which is connected to a complex mechanism that usually includes high-strength materials such as steel wire or nylon wire. When the knob is turned, these materials will tighten or loosen accordingly, thereby changing the tightness of the shoelaces. Unlike traditional shoelaces, the quick lacing system usually uses specially designed shoelaces that are thinner, lighter, and can work better with the internal mechanism.
[0003] However, most of the knobs inside the shoe buckle can only be tightened in one direction but cannot rebound, resulting in the shoe laces having to be loosened and pulled out manually when the shoe laces need to be loosened, which is troublesome and time-consuming. Therefore, we propose a shoe buckle with a rebound function to solve the above problems. Summary of the invention
[0004] The purpose of the present invention is to provide a shoe buckle with a rebound function to solve the problem in the above-mentioned background technology that most of the knobs inside the shoe buckles can only be tightened in one direction but cannot rebound automatically, resulting in the shoelaces having to be loosened and pulled out manually when the shoelaces need to be loosened, which is troublesome and easy to waste time.

When the base is engaged with the ratchet gear, the surface cover drives the wire wheel to rotate in one direction and the elastic spring contracts. When the surface cover drives the ratchet gear to move upward via the connecting rod, the base is disengaged from the ratchet gear and the elastic spring drives the wire wheel to rebound in the opposite direction.
[0006] Preferably, a first plug interface is provided at the bottom of the wire wheel, and the other end of the elastic spring is engaged with the first plug interface, and a second plug interface is provided on one side of the inner part of the base, and one end of the elastic spring is engaged with the second plug interface.
