Abstract

The invention discloses an olive-shaped back floater; a lightweight material which can float on water surface is made into a float block, the float block is cuspidal in both ends, and is olive-shaped in the middle part, two belt through holes are arranged at the middle part of the float block, and the belt through holes are long-strip-shaped, are arranged in parallel and run through the float block; a fabric is used as a tying belt, the tying belt is band-shaped, two ends of the tying belt respectively pass through the two belt through holes and are pulled tightly. The olive-shaped back floater has small resistance in water and small impact on user swimming speed, is particularly suitable for using as a protective article by a swimmer in the wild swimming, is simple in structure and is easy to produce.

Description

technical field [0001] The invention relates to a swimming tool, in particular to an olive-shaped back float. 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 user's swimming speed, the present invention provides an olive-shaped back float. The olive-shaped back float has low resistance in water, so it has little influence on the user's swimming speed It is especially suitable for swimmers to use as protective equipment when swimming in the wild. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a floating block is set with a light material capable of floating on the water surface, the floating block is olive-shaped with sharp ends and a thic...
