Disclosed is an oscillating type buffering device for a car pressing mechanism of a car dumper comprises a stop lever (1), a counterweight (2), and a buffer (3). The buffer (3) comprises an oscillating rod (5), a spring I (6), a spring II (7), an upper baffle (8), a middle baffle (9), and a lower baffle (10). The oscillating rod (5) comprises a head portion (11) and a rod portion (12). The rod portion is fixedly connected to the lower baffle after penetrating through the middle baffle. The spring I is arranged between the upper baffle and the middle baffle, and the spring II is arranged between the middle baffle and the lower baffle. The middle baffle is hingedly connected to a lower portion of the stop lever by means of a hinging point II (14), and the head portion is hingedly connected to the counterweight by means of a hinging point III (15). According to the device, based on the principle that rotatable rod parts under tension and compression only are hingedly connected at two ends, the problem of bending damage to a loop bar due to transverse force is solved by the rotation of the rod parts, and meanwhile the problems of buffering and compression are solved by the oscillating rod and the rotatable hollow middle baffle; the device has the advantages that the structure is compact and reliable, and the stress is simple and reasonable.
