The invention discloses a capacity increasing type trolley frame and a trolley, and belongs to the technical field of trolleys. The device mainly comprises four sets of vertical rods, and long-strip-shaped holes are vertically formed in the vertical rods. The inner rod is inserted into the vertical rod in a sliding mode, an insertion hole is formed in the bottom of the inner rod, and a pin shaft is arranged in the insertion hole; the middle sleeve is arranged on the outer ring of the vertical rod in a sleeving manner and is mounted with the pin shaft; the top sleeve is arranged on the outer ring of the inner rod in a sliding and sleeving manner; the lower cross rod is hinged to the middle sleeve; the upper cross rod is hinged to the top sleeve; the middle cross rod is mounted at the tail ends of the upper cross rod and the lower cross rod; the lower fork rod is hinged to the middle sleeve; and the upper fork rod is hinged on the top sleeve. According to the increased capacity increasing type trolley frame and the trolley, by arranging the frame mechanism, when the trolley is stored, the space of the trolley in the length direction and the width direction can be relieved through capacity increasing in the height direction, and the purpose of increasing the cargo carrying capacity of the trolley is achieved.
