Description

Technical Field

[0001] The utility model relates to the field of cycling helmets, in particular to a cycling helmet which is easy to adjust. Background Art

[0002] Cycling is a healthy and environmentally friendly way to travel. It allows you to exercise, enjoy the scenery, and make friends. It can also improve memory. Cycling improves memory for both strong and weak memory holders, alleviates Parkinson's disease, and improves activity in brain regions associated with movement. Cycling can also help prevent cancer. Daily lack of exercise is one of the unhealthy behaviors that can easily lead to cancer. Long-term cycling can enhance cardiovascular function, especially aerobic exercise, improve metabolism and immunity, and play a role in fitness and cancer prevention. Consequently, more and more people enjoy cycling outdoors in their free time.

[0003] During cycling, due to the high speeds involved, a head collision is very likely to occur in the event of an accident. The head is one of the most vulnerable parts of the human body, and serious damage can have devastating consequences. Therefore, wearing a helmet is an essential safety measure for cyclists, effectively protecting the head from accidental injuries. The materials, structure, and design of cycling helmets have been carefully considered and tested to withstand high-speed collisions and impact forces. Cycling helmets are generally made of lightweight materials, such as EPS (polystyrene) foam, which offers excellent impact resistance and shock absorption. The brim of the helmet provides protection from sunlight and dust, while also providing some cushioning in the event of a collision.

[0004] Existing cycling helmets are usually provided with nylon straps inside to fix the helmet to the rider's head through the nylon straps. The inner wall of the cycling helmet is provided with a headband, which is usually made of webbing or plastic. The size of the headband is fixed. Riders choose a specific helmet according to the size of their own heads. When the size is not suitable, the headband can only be replaced, which is not convenient to use. Utility Model Content
