Abstract

The invention relates to a hemispherical end cylindrical back float, which is provided with a floating block made of a light material able to float on a water surface. The floating block is cylindrical, and two ends of the floating block are hemispherical. The middle part of the floating block is provided with two strip lace holes, which are arranged in parallel and run through the floating block. Fabric is employed to make a banded ligament, two ends of which pass through the lace holes respectively and are then strained. The hemispherical end cylindrical back float not only has small resistance in water and small impact on the swimming speed of a user, and is also especially suitable for swimmers to use as a protective article during swimming in the wild. The hemispherical end cylindrical back float has a simple structure and is easy to produce.

Description

technical field [0001] The invention relates to a swimming tool, in particular to a cylindrical back float with a hemispherical end. Background technique [0002] At present, the known back floats are block-shaped, and block-shaped back floats have high resistance in water, thus affecting the swimming speed of the user. Contents of the invention [0003] In order to overcome the disadvantages of existing back floats that have high resistance in water and affect the swimming speed of users, the present invention provides a cylindrical back float with a hemispherical end. The impact of swimming speed is small, and it is especially suitable for swimmers to use as protective equipment when swimming in the wild. [0004] The technical solution adopted by the present invention to solve its technical problem is: adopt the lightweight material that can float on the water surface to set a floating block, the floating block is cylindrical, and the two ends of the floating block are...
