Description

Leak-proof sealing sleeve for oil pipe joint Technical Field The utility model belongs to the field of oil pipe sealing sleeves, and particularly relates to an oil pipe joint leakage-proof sealing sleeve. Background The leak-proof sealing sleeve of the oil pipe joint is generally used for sealing the joint of the oil pipe and preventing oil from leaking, and can be used in industries such as petroleum, natural gas, chemical industry and the like, especially when working in a high-pressure or high-temperature environment. The existing oil pipe sealing sleeve is mainly used for filling and sealing gaps between an oil pipe joint and an oil pipe through various sealing gaskets, but the effect of the single sealing mode is often reduced due to ageing of the sealing gaskets in the actual use process, and the single sealing structure is difficult to meet the requirement that the oil pipe cannot fall off in the use process, so that the firmness and the tightness of the oil pipe in installation and use are affected. Therefore, aiming at the problems that the sealing performance of the existing oil pipe joint sealing sleeve is poor and the oil pipe is easy to fall off during use, the sealing performance of the oil pipe joint sealing sleeve during use can be greatly improved by additionally arranging the inner and outer double-layer sealing structure, the arc-shaped limiting structure and the barb limiting structure on the oil pipe sealing sleeve, and the possibility that the oil pipe falls off from the joint accidentally is reduced. Disclosure of utility model In order to solve the problems that the sealing sleeve of the existing oil pipe joint has poor tightness and the oil pipe is easy to fall off when in use. The technical scheme includes that the anti-leakage sealing sleeve for the oil pipe joint comprises an oil pipe main body, a sealing sleeve main body, a threaded cap, a rubber sleeve and a metal limiting ring, wherein a thickening layer and a plurality of groups of rubber ring sheets distributed at equal intervals are sequentially arranged on the outer wall of the rubber sleeve from front to back, a plurality of groups of metal barbs distributed at equal intervals around the inner wall of the metal limiting ring and symmetrical front to back are fixedly connected to the edge of the inner wall of the metal limiting ring, a first groove body is formed in the edge of the front end of the sealing sleeve main body, a first rubber ring is arranged in the first groove body, a second rubber ring is arranged on the edge of the rear end of the sealing sleeve main body, and a third rubber ring is arranged on the inner wall of the front end of the threaded cap. Preferably, the front end of the sealing sleeve main body is fixedly connected with a first thread cylinder, the rear end of the sealing sleeve main body is fixedly connected with a second thread cylinder, and the metal limiting ring is arranged on the outer wall of the thickening layer.
