Description

Cap body buckle adjustment structure

The present invention is a cap buckle adjustment structure which is assembled on the inner edge of the cap and is appropriately adjusted according to the head circumference of different users so that the cap body can be stabilized on the user's head. Background technique

The locomotive is a mobile and convenient vehicle, so the frequency of the Volkswagen locomotive is second only to mass transit. Due to the large number of steam and locomotives, the traffic is more and more complicated, and the distance between the vehicle and the vehicle is easy to be too close, and if the driver is inferior and the attention is not good, it is easy to cause a traffic accident. When riding a locomotive, the locomotive rider is not as hard as the car driver has to resist the impact of the collision. Therefore, in order to protect the riding safety of the locomotive rider, it is necessary to wear a helmet when riding, so as to reduce the traffic accident to the locomotive. The damage caused by the knight. Of course, the helmet is not only used to protect the knight when riding a locomotive, but also to protect the safety of the constructor's head and prevent the constructor from being hit by heavy objects hitting the head during construction.

The helmet needs to be completely covered with the head and tightly worn on the head to achieve perfect protection measures. For this reason, the industry has developed a "safety cap for convenient adjustment of the buckle" as disclosed in Taiwan Patent Notice No. M408961. In the helmet structure of the Taiwan Patent Publication No. M414104 "Hard Cap Construction", the above-mentioned helmets are only fastened to the chin by the adjusting buckle, so that the helmet is not easily separated from the head. However, the head circumference of a general user varies from person to person, and the space size of the well-known hard hat accommodating head is fixed. When the user is not wearing the size, when the user's head circumference is too large, If the user's head circumference is too small, the head and the helmet can not be tightly fitted, so that the helmet can slide or shake relative to the head, left and right, and the best protection effect can not be achieved. Therefore, the known helmet can only make different head circumferences by making helmets of different sizes, which makes the production costly and time consuming. Therefore, it is necessary to develop a cap buckle adjustment structure suitable for different head circumference sizes. Summary of the invention
