Lubricating indirect oil supply mechanism not limited by stroke

The utility model relates to a lubrication indirect oil supply mechanism not limited by stroke, which comprises a moving part and a guide part which are mutually sealed and are in sliding fit, and a closed oil cavity is formed between the moving part and the guide part; an oil injection hole communicated with the oil cavity is formed in the guide part; a horizontal pipe cavity and a plurality of vertical pipe cavities which are perpendicular to and communicated with the horizontal pipe cavity are formed in the moving part, and lubricating oil does not overflow from one end, located on the bearing, of the horizontal pipe cavity; a one-way valve A is arranged at the oil inlet end of the vertical pipe cavity; the distance between every two adjacent vertical pipe cavities is not larger than the size of the oil cavity in the moving direction. A key lubricating part is arranged at one end of the moving part, and the horizontal pipe cavity is used for supplying oil to the key lubricating part. Therefore, the stroke
