Breast stroke posture training machine employing connecting rod in orbit constraint

Abstract

The invention relates to a breast stroke posture training machine employing a connecting rod in orbit constraint, belonging to the field of sport equipment; a four-connecting rod mechanism is employed to constrain the hand and foot orbits of breast stroke, and no motor is used so as to reduce the injury possibility of the practicers during the training process; supporting rods are used for supporting the wrists and ankles, so that the structure is simple and compact and that the orbit is accurate and normative; besides, the training machine can be used for guaranteeing the hands to approach the orbits on a spherical surface to be more anastomotic with the standard breast stroke action than a planar orbit; the training machine can be used by practicers with different heights and arm lengths, and the training machine has the advantages of easy control and operation, low cost and convenience for assembly and maintenance, so that the training machine is very suitable for the breast stroke beginners to train the swimming postures.
