Preferably, the safety assembly comprises an adjusting ring, threads are etched on the outer surface of the fixed pipe, and the adjusting ring is inserted into the fixed pipe and rotationally engaged with the outer surface of the fixed pipe.

Preferably, the depth of the U-shaped groove is half of the height of the fixed pipe.

Preferably, a cannula is arranged at the joint of the socket joint and the safety component and is inserted into a tube cavity arranged in the socket joint and the safety component.

Preferably, the jacket is made of soft rubber.

Preferably, the inner diameter of the fixing tube is larger than the outer diameter of the cannula, and the inner diameter of the jacket is smaller than the outer diameter of the cannula.

The utility model has the advantages that:

1. the utility model discloses based on the intubate inserts to insurance subassembly and socket joint in, and then presss from both sides the annular surface department of cover application pressure in the intubate in fixed pipe department, avoid the intubate insert to the socket joint in the back, because of the not hard up fixed not jail that leads to of bolt joint, the not good problem of sealed effect that causes then.

2. The utility model discloses an adjusting ring bolt connects in the annular surface department of fixed pipe to when fixing the intraductal cover that presss from both sides carries out annular centre gripping to the intubate, based on the adjusting ring for the rotational position of fixed pipe, come to adjust the clamping dynamics, in order to avoid because of the centre gripping dynamics is not good, the insecure phenomenon of insurance that leads to.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand, the present invention will be further explained below with reference to the following embodiments and the accompanying drawings, but the following embodiments are only the preferred embodiments of the present invention, and not all embodiments are included. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

Example 1

As shown in fig. 1-3, a steel pipe socket joint with good sealing performance comprises a socket joint 1, three ports are arranged at the socket joint 1, the three ports are connected with a safety component 2, and the safety component 2 comprises a connecting pipe 21, a fixed pipe 23 and a jacket 24; a connecting pipe 21 is connected at the port of the socket joint 1, the outer end of the connecting pipe 21 is connected with a fixed pipe 23, three groups of U-shaped grooves are distributed on the side wall of the fixed pipe 23 in an annular manner, and the depth of each U-shaped groove is one half of the height of the fixed pipe 23; the inner wall of the fixing tube 23 is bonded with a jacket 24, the jacket 24 is made of soft rubber, the inner diameter of the fixing tube 23 is larger than the outer diameter of the insertion tube 3, and the inner diameter of the jacket 24 is smaller than the outer diameter of the insertion tube 3.
