The invention discloses a sewing-
machine self-lubricating oil-storage connecting rod mechanism. The sewing-
machine self-lubricating oil-storage connecting rod mechanism comprises a large connecting-rod eccentric wheel. The surface of an outer ring of the large connecting-rod eccentric wheel is matched with a large connecting rod, one side of the large connecting-rod eccentric wheel is matched with a large-connecting-rod-eccentric-wheel fixing frame, the other side of the large connecting-rod eccentric wheel is matched with a cloth feeding
cam pressing piece, a set of felt
cushion blocks are arranged in the large-connecting-rod-eccentric-wheel fixing frame, a large-connecting-rod-eccentric-wheel shaft hole is formed in the large connecting-rod eccentric wheel, and an upper shaft is arranged in the large-connecting-rod-eccentric-wheel shaft hole, and sequentially penetrates through the large-connecting-rod-eccentric-wheel fixing frame, the large-connecting-rod-eccentric-wheel shaft hole and the cloth feeding
cam pressing piece. The sewing-
machine self-lubricating oil-storage connecting rod mechanism has the advantages that when the large connecting-rod eccentric wheel moves, lubricating oil of the felt
cushion blocks is automatically oozed out to lubricate the large connecting-rod eccentric wheel, the self-lubricating effect is achieved, it is avoided that abrasion of the large connecting-rod eccentric wheel appears to cause damage, the service life of a
sewing machine is prolonged, the felt
cushion blocks only need to be filled with lubricating oil during maintaining, the felt cushion blocks can be reused, the using effect is good, and popularization is facilitated.
