TECHNICAL FIELD

[0001] The utility model relates to body -building equipment technical field especially, a kind of hanger for weight block pin shaft of body -building equipment. BACKGROUND

[0002] The main role of the hanger for weight block pin shaft of body -building equipment is to fix and adjust the weight block, so as to help the exerciser adjust the training intensity and realize personalized exercise plan. The main role of the pin shaft is to connect and fix the weight block, to ensure its stability and safety on the body -building equipment. The pin shaft for weight block cooperates with other components, firmly connects the weighter and the machine equipment, so that the body -building equipment can bear the increase of weight and the operation of the machine equipment. In the body -building equipment, the specific application of the weight block pin shaft is very extensive. For example, on the equipment such as chest push, shoulder push and leg flexion, the weight block pin shaft is used to connect and fix the weight block of different weights to meet the needs of different exercisers. By simply inserting and pulling out the pin shaft, the exerciser can easily adjust the difficulty of training to realize targeted exercise on different muscle groups.
