Abstract
The utility model relates to an anti-leaking oil type needle bar guide sleeve, which relates to a needle bar guide sleeve. The utility model mainly solves the technical problem that the exiting needle bar guide sleeve is easy to leak oil, etc. The utility model has a technical scheme that the utility model comprises a guide sleeve body of a needle bar and a needle bar installing hole which is arranged in the guide sleeve body of a needle bar, wherein the internal wall of the needle bar installing hole is provided with circular oil scraping grooves, the internal parts of which are provided with an oil return hole which passes through the guide sleeve body of a needle bar, the lower end of which is provided with an oil return groove and the internal part of the oil return groove is provided with the oil return hole which is communicated with the needle bar installing hole. The internal part of the wall of the guide sleeve body of a needle bar can be also provided with a ventilating hole which is communicated with the oil return hole, and the upper end of the ventilating hole is communicated with the external end of the needle bar installing hole. Or the external end of the oil return hole on the external wall of the guide sleeve body of a needle bar and the external end of the oil inlet hole are connected with an oil return pipeline. The internal part of the needle bar installing hole of the guide sleeve body of a needle bar can be provided with one to six circular oil scraping grooves. Through the arranged oil scraping grooves, the oil return hole, and the oil return groove, the utility model can efficiently prevent an oil leaking phenomenon when the needle bar and the needle bar guide sleeve are matched for moving.
