Abstract
A novel connecting rod pin is a part of an oilfield pumping unit, overcoming defects of the prior art. A first groove, a third groove are arranged at the two ends of the connecting rod pin, a second groove is arranged in the middle of the connecting rod pin, and a first side hole, a second side hole and a third side hole are respectively arranged below the first groove, the second groove and the third groove. A first grease nipple and a second grease nipple are respectively arranged on the two sides of the connecting rod pin, a first oil charging hole is communicated with the first grease nipple, and two ends of the first oil charging hole are respectively communicated with the first side hole and the second side hole. A second oil charging hole is communicated with the second grease nipple, and the second oil charging hole is communicated with the third side hole. Since the grooves and the side holes are additionally arranged at the two ends of the connecting rod pin, grease enters the side holes into the grooves through the grease nipples and the oil charging holes so as to lubricate and protect the two ends of the connecting rod pin.
Description
Technical field
The utility model relates to a kind of parts on the oil-field oil pumper, especially novel link pin.
Background technique
Because pumping unit all is to work in the open air, rainwater is easy to corrode link pin, and the time has been grown two and will get rusty; Because link pin is stressed big, will send the sound of creak creak, wearing and tearing will come off after the corrosion; Will influence intensity, even fracture influences the pumping unit quality.Old-fashioned connecting rod two does not have groove, and butter is lubricated and protects in the middle of just cannot getting into link pin and crossbeam strengthening sleeve.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure; Easy to operate novel link pin; It has overcome the shortcoming that original technology exists; The purpose of the utility model is achieved in that it is to be formed by connecting first groove, second groove, the 3rd groove, first grease nipple, second grease nipple, first oil hole, second oil hole, first side opening, second side opening, the 3rd side opening, link pin, is provided with first groove, the 3rd groove at link pin two; First groove is arranged wherein, be provided with first side opening, second side opening and the 3rd side opening respectively in the bottom of first groove, second groove and the 3rd groove; Be provided with first grease nipple and second grease nipple respectively in the both sides of link pin, on first grease nipple, be communicated with first oil hole, the first oil hole two ends are being communicated with first side opening, second side opening respectively; On second grease nipple, be communicated with second oil hole, second oil hole is communicated with the 3rd side opening.
Working principle: because link pin two has increased groove and side opening, butter gets into side opening to groove through grease nipple and oil hole, and connecting rod two is lubricated and protects.
The practicability of novel link pin: the improved connecting rod of process is owing to can lubricate and protection connecting rod two; Just be not afraid of the erosion of wind and rain; Can not get rusty, just can not send the sound of creak creak, link pin and strengthening sleeve just can not wear and tear; Improve the quality of pumping unit, increased the working life of pumping unit.
