Onshore breaststroke learning machine

Abstract

The invention discloses an onshore breaststroke learning machine. The onshore breaststroke learning machine comprises an upper limb movement mechanism, a trunk movement mechanism and a lower limb movement mechanism; the upper limb movement mechanism comprises upper limb tracks, arm pull slider assemblies, a motor induction switch and a lower limb stopper induction switch; each arm pull slider assembly slides to the initial position of the arm pull state along the corresponding upper limb track, and the motor induction switch sends out a signal to control the trunk movement mechanism to act; when the arm pull slider assemblies slide to the upper limb withdrawing positions, the lower limb stopper induction switch sends out a signal to control the lower limb movement mechanism to complete one time of leg drive movement; the lower limb movement mechanism comprises lower limb tracks, leg drive slider assemblies, foot hitching plates, connection pieces and lower limb stoppers. The first connection pieces are flexibly connected with the leg drive slider assemblies and the foot hitching plates; the leg drive slider assemblies slide to the lower limb withdrawing positions along the lower limb tracks, the lower limb stoppers receive the signal of the lower limb stopper induction switch, and the sliding is allowed or stopped. By means of the onshore breaststroke learning machine, the standard property of the breaststroke movement gesture and the coordination property of the movement time are ensured.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a land breaststroke learning machine. Background technique [0002] Breaststroke is a learning event for beginner swimmers. When teaching breaststroke manually, due to the standardization of learning movements and the coordination of movement time, it is difficult to fully grasp it in a short period of time. During the learning period, it is especially easy to choke on water, prolonging the learning time of beginners, or causing beginners to fear and give up learning swimming. Time consuming wreck. [0003] In addition to artificial teaching breaststroke, a swimming learning machine in the prior art is a hanging basket equipped with a safety belt connected to a pillar on land. The hanging basket is fixed on the chest of the person, and the person is lifted and suspended in the water, and the hands and feet are simulated in the water. Various swimming moves. The disad...
