Pedal linkage and exercise machine

Abstract

The utility model discloses a footboard linkage mechanism and body builder, and relates to the field of body building equipment. Its technical scheme includes: stress structure, and this structure contains the first rotary joint part of rotatable connection with external support structure, and its both sides are equipped with first force connecting part and first linkage connecting part respectively; footboard unit, including footboard; guide unit, and footboard linkage; first linkage structure, between stress structure and footboard, when the stress structure rotates with the first rotary joint part as the axle, first linkage structure drives footboard to move in the range of guide unit limit. Advantageous effects are: realize the linkage of crouching action and footboard, make shank and foot at the ankle joint place always be in the close vertical range during training, reduce the ankle joint injury probability, and can complete the maximum degree crouching simultaneously, distribute the training resistance as much as possible to the target hip muscle group, improve training efficiency greatly.
