AI Technical Summary
Technical Problem
Traditional threaded pipe connections are prone to rust, breakage, and explosion, are difficult to seal, and are difficult to control the angle of connection.
Method used
A sealing device including a threaded pipe and an elastic rubber ring is used. A seal is formed in the threaded connector through the squeezing action of the elastic rubber ring, and the angle is adjusted by a rotating tool.
Benefits of technology
It improves the sealing performance, avoids rust and breakage, and facilitates angle adjustment without affecting the sealing effect.

Abstract
The utility model belongs to a sealing device, and particularly relates to a sealing device of a screw thread connecting piece, which comprises a screw thread pipe fitting and an elastic rubber ring, one end of the screw thread pipe fitting is provided with an outer screw thread, the other end of the screw thread pipe fitting is sleeved with the elastic rubber ring, the outer screw thread of the screw thread pipe fitting is connected with an inner screw thread of the screw thread connecting piece, and the elastic rubber ring is sleeved with the outer screw thread. The outer screw threads of the screw thread connecting pieces abut against the outer sides of the elastic rubber rings on the screw thread pipe fittings and are tightened with the inner screw threads of the screw thread connecting pieces, compared with a traditional expansion sealing method, the sealing performance is higher, and meanwhile when a certain azimuth angle needs to be adjusted between the screw thread connecting pieces, the screw thread connecting pieces are convenient to adjust under the action of the elastic rubber rings, and the sealing effect is not affected.
