Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a helmet with plug-in lenses. Background Art

[0002] A helmet is a piece of equipment that protects the head, usually consisting of a hard outer shell and an inner lining. Its main function is to protect the head from impact or scratches during sports, work or other activities. The design and use of helmets can be traced back to ancient times, but modern helmets have developed into many different types and uses. In sports, helmets are widely used to prevent athletes from getting injured. For example, cyclists, skateboarders, skiers, ice hockey players, etc. all wear helmets.

[0003] Currently, the existing helmet lenses rotate with the two end points as the center, which is very safe and stable during use. The lenses will be firmly fixed on the helmet and will not fall off easily due to impact. However, this design also has certain defects. When the helmet lenses are damaged or cracked, it will affect the rider's vision, and it is difficult to disassemble. The helmet lenses cannot be replaced in time when needed. In view of this, we provide a helmet with plug-in lenses. Utility Model Content

When installing the windproof lens 2, it is only necessary to slightly bend the windproof lens 2 outwards, and align the circular hole opened in the center of the mounting buckle 3 with the circular hole opened on one side of the outer wall of the resistance block 505. Sliding inclined surface 506, when the mounting buckle 3 is pressed toward the side of the resistance block 505, the resistance block 505 compresses the resistance spring 502 as the mounting buckle 3 is pressed. When the mounting buckle 3 is completely sleeved on the outer wall of the limiting buckle 401, since the limiting buckle 401 is elliptical as a whole, it effectively limits the rotation of the mounting buckle 3 on the outer wall of the limiting buckle 401. The resistance spring 502 has its own elasticity and pushes the driving slider 504 and the resistance block 505 to slide away from the resistance spring 502, and installs the mounting buckle 3 and the windproof lens 2 on one side of the outer wall of the helmet body 1, so that the lens can be quickly installed by installing the mounting buckle 3 on both sides of the windproof lens 2.
