Description

Technical Field

[0001] This utility model relates to an auxiliary wheel frame locking and adjustment structure, specifically to an auxiliary wheel frame locking and adjustment structure with a more robust structure. Background Technology

[0002] Note that two-wheeled vehicles rely on balance, but people with poor balance or who are still training often use training wheels on the rear wheels. This ensures that there are at least three points of contact with the ground when balance is lost, thus preventing tipping over. We have been dedicated to the manufacture and design of training wheel frames, and have previously created the “Training Wheel Assembly Frame Structure” in Taiwan Patent No. M459158. However, existing training wheels still have the following drawbacks: when these lightweight training wheels are driven at high speeds, such as when installed on electric vehicles, the existing training wheels cannot withstand the force and bend, thus losing their function. Therefore, a more robust training wheel frame is needed.

[0003] Therefore, the inventor of this utility model, in view of this, conceived the idea of ​​creation, and designed it based on many years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, this utility model was finally launched. Utility Model Content
