Helmet bringing convenience to handstand rotation for street dancer

Abstract

The invention belongs to the field of sports equipment, and relates to a helmet bringing convenience to handstand rotation for a street dancer. The helmet is characterized in that a lower circular plate and an upper circular plate of a grounding face are hinged to each other in a clearance fit mode through a shaft, an elastic cushion is arranged on the upper circular plate, a hook-shaped adhesion piece is arranged on the inner side of the outer end of a forehead fastening belt in a sewn mode, an annular adhesion piece is arranged on the outer side of the inner end of the forehead fastening belt in a sewn mode, ten cloth sleeves are arranged outside the forehead fastening belt in a sewn mode, and the left end of a rope penetrates through ten annular holes and ten cloth sleeve holes formed in the upper circular plate in an alternating mode so that the upper circular plate can be connected with the forehead fastening belt to form the overall structure of the helmet. The depth of the helmet can be adjusted after the left end or right end of the rope stretches or contracts and is tied. The adhesion pieces can be connected by tensioning the outer end of the forehead fastening belt, and then different forms of heads of users can be fastened. On the basis that the roughness and friction coefficients of the upper surface of the lower circular plate and the roughness and friction coefficients of the lower surface of the upper circular plate are small, the upper circular plate and the lower circular plate can rotate freely relative to each other.

Description

technical field [0001] The invention belongs to the field of sports equipment, and relates to a helmet that is convenient for hip-hop heads to rotate upside down. Background technique [0002] Human head inversion rotation is one of the action contents of practicing hip-hop. The current use of similar basin-shaped helmets to perform human head inversion rotation has the following problems: a. When the outer top of the helmet is in contact with the rough ground, the outer surface of the helmet is in contact. The relative rotation of the top and the ground will be reduced, and the accompanying will cause the relative rotation of the hair scalp and the inner top surface of the helmet, and the friction, heat generation and grinding will easily damage the hair and scalp; b. The function of adjusting the size and depth is not universal. SUMMARY OF THE INVENTION [0003] In order to better solve the problems existing in the above-mentioned background technology, the purpose of t...

[0002] The headstand rotation of the human head is one of the action content of hip-hop practice. The existing problems of using the approximate basin-shaped helmet to carry out the headstand rotation are: a. When the outer top of the helmet contacts the rougher ground, the outer surface of the helmet The relative rotation between t
