Abstract
The utility model relates to a take-up device for a strength training instrument, and the take-up device comprises two winding bodies which are provided with winding grooves, and the two winding bodies are symmetrically arranged; the driven wheels are in one-to-one correspondence with the winding bodies and are used for being connected with a resistance source and transmitting resistance; the coil springs are arranged in the winding bodies, when the winding bodies rotate in the wire outlet state, the coil springs are wound, and when the pull wires on the winding bodies are released, the coil springs drive the winding bodies to rotate reversely so as to achieve wire winding; the two ends of the main shaft penetrate through the two winding bodies respectively, the main shaft is connected with the driven wheel through a one-way bearing, and the main shaft is coaxially and rotationally connected with the winding bodies and the coil spring. An additional motor does not need to be adopted as a take-up power source, the structure is simple, the driven wheel can be connected with various resistance sources, and the equipment cost can be remarkably reduced.
