The utility model aims to overcome the defects of the prior art, and provides the steel pipe connector which has the advantages of good anti-leakage effect, simplicity and rapidness in installation, time and labor saving, low requirements on the installation technology, low cost, high pressure bearing, convenience in maintenance and long service life, and can be realized without other tools.

The aim of the utility model is achieved by the following technical measures: the utility model provides a steel pipe connector, includes the connector, and the upper end of connector has the link, and the inside of link has annular toper draw-in groove, and connector threaded connection has the knot cap, is equipped with toper rubber ring and metal gasket in proper order between connector and the knot cap, and toper rubber ring setting is in toper draw-in groove, and toper rubber ring cooperatees with the toper draw-in groove.

As a further improvement of the above technical scheme:

the conical rubber ring is annular conical, and the diameter of the upper end of the conical clamping groove is larger than that of the lower end.

The bottom of the conical clamping groove is a horizontal plane.

The periphery of the connecting end is provided with external threads, and the connector is in threaded connection with the buckling cap through the external threads.

The inner periphery of the conical rubber ring is round.

The metal gasket is arranged above the conical rubber ring.

The outer diameter of the metal gasket is equal to the outer diameter of the connecting end.

The buckling cap is arranged above the metal gasket.

The inside of the button cap is provided with internal threads.

The center of the upper part of the buckling cap is provided with a circular through hole.

Due to the adoption of the technical scheme, compared with the prior art, the utility model has the advantages that: when the steel pipe anti-leakage device is used, the steel pipe is directly inserted into the steel pipe connector, at the moment, the end part of the steel pipe sequentially penetrates through the metal gasket and the conical rubber ring in the steel pipe connector, and the conical rubber ring is pressed by pressure to achieve the purposes of fixing the steel pipe and preventing leakage, so that the anti-leakage effect is good; the installation is simple and quick, time and labor are saved, the requirement on the installation technology is low, the installation can be realized without other tools, the cost is low, the bearing pressure is high, and the service life is long; in addition, when maintenance is needed, the button cap is unscrewed, and the maintenance is simple and convenient.

The utility model is further described below with reference to the drawings and the detailed description.
