For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the few air compressor of a kind of oiling number of times, comprises housing, connecting rod, oil absorbent material ring, bent axle and sealing plug; Described bent axle includes a bent axle body and is connected the eccentric coupling shaft connecting in bent axle body two ends, described connecting rod, bent axle body and coupling shaft are arranged in housing, wherein the sidewall of coupling shaft and housing is rotatably supported in the sidewall of housing, and connecting rod and bent axle body are hinged; Described bent axle body and coupling shaft are provided with a circular groove, and from shaft axis separately to the through hole that is provided with annular spread circumferential surface, described circular groove is communicated with through hole, described oil absorbent material ring set is connected on circular groove, described bent axle body is also provided with the oil inlet hole of a connecting through hole, and described sealing plug and oil inlet hole are tightly connected.
The through hole of described bent axle body and coupling shaft respectively has four.
The outer side surface of described oil absorbent material ring is the arc surface of indent.
Between described coupling shaft and sidewall and between connecting rod and bent axle body, be provided with a bearing, described bearing is fixedly mounted on respectively on sidewall and connecting rod, and forms revolute pair with coupling shaft and bent axle body respectively.
The material of described sealing plug is rubber.
(3) beneficial effect
The few air compressor of oiling number of times of the present utility model.By being provided with a circular groove at bent axle body and coupling shaft, and at circular groove socket oil absorbent material ring, thereby can will be injected in circular groove from through hole, and absorb oil absorbent material ring, thereby further increase the holding space of oil storage, the oil filling amount of per injection is increased, relatively reduced the number of times of oiling, make oiling more convenient to operate.
Accompanying drawing explanation
